Abstract:
In order to meet ambitious growth targets in the medium term, Vietnam must continue exploiting traditional energy sources. In the longer term, Vietnam has to develop a strategy and roadmap for the development of new energy sources. In these new energy sources, wind energy has emerged as a viable option. Given the geographic conditions of a locality with a long coastline and high winds that are fairly distributed all year, many wind-power plants are being built in Vietnam. One of the most important pieces of equipment in a wind-power plant is the wind turbine. The wind turbine suppliers’ selection is a complex and multicriteria decision-making (MCDM) process that can reduce the costs of procuring equipment and aid in receiving products on time. Many studies have applied the MCDM model to various fields of science and engineering. One of the fields that the MCDM approaches have been applied to is the supplier selection problem. Supplier selection is an important issue of the MCDM model. Especially in a renewable energy project, decision-makers have to evaluate both natural and society factors. Although some researchers have reviewed the applications of the MCDM model in wind turbine supplier selection, limited work has focused on this problem in a fuzzy environment. Therefore, in this work, the authors propose a fuzzy MCDM model for the wind turbine supplier selection process under fuzzy environment conditions. In the first step, all factors for wind turbine supplier selection are identified by supply chain operations reference (SCOR) metrics and the results from a review of the literature. A fuzzy analytic network process (FANP) model is applied for determining the weight of all the criteria in the second stage, and the technique for order preference by similarity to an ideal solution (TOPSIS) model is used to rank all the potential suppliers in the final stage. As a result, Decision-Making Unit 010 (DMU010) becomes an optimal option for the wind turbine supplier selection processes. The contribution of this research is to develop new hybrid fuzzy MCDM approaches for wind turbine supplier selections. Furthermore, this work presents useful guidelines for wind turbines as well as provides a guideline for supplier selection in other industries.

Abstract:
Supplier evaluation and selection is becoming more and more important for companies in today’s logistics and supply chain management. Decision making in supplier selection domain, as an essential component of supply chain management, is a complex process due to the fact that a wide range of diverse criteria, stakeholders and possible solutions are embedded into this process. This paper focuses on the application of some single and hybrid multi criteria decision making approaches for the selection of suppliers of transportation and logistics equipment. The analytic hierarchy process (AHP), stepwise weight assessment ratio analysis (SWARA) and technique for the order preference by similarity to ideal solution (TOPSIS) have been implemented in the "Lagerton" company in Serbia for evaluation and selection of the supplier in the case of procurement of THK Linear motion guide components. The best ranked supplier has been suggested to the company and the sensitivity analysis of ranking orders according to the criteria weights variations has been done.

Abstract:
Over the last decade, several non-Saccharomyces species have been used as an alternative yeast for producing wines with sensorial properties that are distinctive in comparison to those produced using only Saccharomyces cerevisiae as the classical inoculum. Among the non-Saccharomyces wine yeasts, Metschnikowia is one of the most investigated genera due to its widespread occurrence and its impact in winemaking, and it has been found in grapevine phyllospheres, fruit flies, grapes, and wine fermentations as being part of the resident microbiota of wineries and wine-making equipment. The versatility that allows some Metschnikowia species to be used for winemaking relies on an ability to grow in combination with other yeast species, such as S. cerevisiae, during the first stages of wine fermentation, thereby modulating the synthesis of secondary metabolites during fermentation in order to improve the sensory profile of the wine. Metschnikowia exerts a moderate fermentation power, some interesting enzymatic activities involving aromatic and color precursors, and potential antimicrobial activity against spoilage yeasts and fungi, resulting in this yeast being considered an interesting tool for use in the improvement of wine quality. The abovementioned properties have mostly been determined from studies on Metschnikowia pulcherrima wine strains. However, M. fructicola and M. viticola have also recently been studied for winemaking purposes.

Abstract:
Viticulture and winemaking are traditional and highly profitable industries in the agricultural sector of Ukraine. The wine industry in Ukraine has considerable potential, but through the rapid changes in both the economic and political situation in the country over the past five years, the dynamics of wine production and sales has deteriorated significantly, although the problems of the wine industry have been studied by many domestic scientists, the issue of tracking the situation remains relevant in the industry, identifying new trends in the development of the industry and obstacles to this development. The purpose of the article is to analyze the current state and dynamics of the development of the wine industry in Ukraine, to identify industry problems and ways to solve them. The dynamics and structure of wine production in Ukraine for the period 2013-2018 are analyzed. It is shown that after a sharp deterioration of the situation in the industry in 2014, wine production in the industry gradually began to grow, but in 2017 there was again a decrease in production volumes. The main players in the markets of sparkling and still wines are identified and changes in the distribution of market shares between producers of still wines for the period 2014-2017 are analyzed. Discovered external and internal factors hindering the development of the industry at the present stage. Thus, high excise taxes amid a decrease in the purchasing power of target markets lead to a decrease in demand for wine products in the domestic market. This does not apply only to table wines, the excise tax on which is not increased. At the same time, competition from foreign wine producers is intensifying. An analysis of the dynamics of exports and imports of wine products showed that although Ukrainian wine producers are gradually increasing their exports and expanding the geography of export supplies, wine imports still significantly exceed exports. The positive changes in the industry include the expansion of areas under vineyards by some manufacturers.Thus, the wine-making industry of Ukraine is gradually recovering after the collapse in 2014, but there are a number of problems that impede the dynamic development of the industry. The solution of these problems requires government support, in particular, the establishment of a zero excise tax rate for sparkling, dry and other types of wine, production technology that does not involve the use of ethyl alcohol, and support for winemakers in promoting domestic wines abroad, which will facilitate the development of new markets.

Abstract. Introduction. Theoretical and practical approaches to marketing research of consumers in the field of wine tourism are considered. Reasonable decision-making is needed for the effective development of the Black Sea Wine Roads project. For this purpose, marketing research was conducted using qualitative and quantitative marketing research (survey, structured interview, content analysis of the text). Purpose. The purpose of the research is to substantiate management decisions for the development of wine tourism in the Black Sea region based on marketing research. Results. A structured interview was conducted with the participants of the ODESSA VINE WEEK event (May 19, 2021), who are stakeholders - the State Agency for Tourism Development of Ukraine, heads of travel agencies, owners and marketers of wineries, etc. The result of the interview was a �portrait of a wine tourist�. A survey of owners of 16 wineries from different regions of Ukraine concluded that the main motives for wine tourists to visit them are the opportunity to try unique local or original wines, high quality wine and use of modern equipment, specially created museums, cultural centers with excursions and wonderful landscapes and picturesque vineyards around. The results of a survey of consumers of wine tourism services are presented. Four main segments among wine tourism connoisseurs have been identified. The first segment is advanced wine connoisseurs, who are mostly united in wine clubs. They have experience in tasting both domestic and foreign wines. They have experience of tasting at wineries. The second segment is Ukrainian tourists who are interested in everything new. They have experience in travel, especially domestic tourism. The third segment � people whose professional activity and purpose of a trip to wineries are directly related to winemaking and tourism. The fourth segment is foreign tourists. Conclusions. The research showed that among modern tourists, the share of those who are looking for an opportunity to add more celebration and pleasure to their holiday in terms of culture and discover new gastronomic feelings combined with fine wines is growing. It is recommended to use the results of the study to form a marketing strategy for the development of the project of wine roads of the Black Sea coast of Ukraine.

Abstract:
A classical approach to monitoring the fer-mentation of grape must based on the use of the areometric method is considered. Based on the processing of the data of measuring the refractive index and density of grape must, as well as data on the physicochemical composi-tion of grape must during fermentation, meth-odological approaches have been developed to create methods for monitoring the composi-tion of the fermenting must using refractomet-ric and refractodensimetric methods of analy-sis. The results of the work can become the basis for the development of a non-destructive express method for determining the volume fraction of ethyl alcohol and the mass concentration of sugars in fermenting must based on the standard equipment of the laboratory of wine-making enterprises, and for the improvement of technical specifications for the manufacture of a portable device for determining the concentration of alcohol and sugar content, based on the simultaneous measuring the refractive index and density of liquid media.

Abstract:
Based on documents from the archives of the French Foreign Ministry and the Russian State Archive of Modern History, the article analyzes Soviet-Algerian relations through the prism of the rivalry between Moscow and Paris in the period from Algeria's independence in 1962 to the nationalization in 1971 by the Algerian leadership of oil transportation facilities and 51% of the shares of French oil companies operating in the Arab state. In the first years after the signing of the Evian Agreements of 1962, loans provided by the USSR, supplies of Soviet equipment, the start of a program to train national personnel, as well as assistance from other socialist countries helped Algeria to stabilize the socio-economic situation in the country. Up until 1968, Moscow's actions in Algeria did not affect strategically important areas for France. However, the aggravation of French-Algerian relations due to Paris' non-compliance with the Algerian wine purchase agreement and, more importantly, the Algerian leadership's desire for independence from France in the oil sector and, at the same time, the beginning of supplies of Algerian wine to the USSR in 1968 and Moscow's assistance in the exploration and exploitation of oil fields in Algeria led to the beginning of the Soviet-French rivalry for the Algerian market. As a result, France and other Western countries were able to impose serious competition on the USSR, significantly reducing Moscow's capabilities in the Algerian direction. The USSR promoted Algeria's independence from France in the oil sector, but failed to make Algeria part of the socialist bloc. The main beneficiary of the Soviet-French rivalry was Algeria itself, which received significant support from the USSR in creating modern industry, agriculture and in the field of training qualified personnel, while retaining ample opportunities to enter Western markets.

Abstract:
Grapes, the quintessential quality factor in winemaking, are found in certain areas of the globe where viticulture thrives. The quality of wine products is directly influenced by the quality of the grapes, their process technology, the care and the quality of the premises and equipment used, as well as the conditions for the storage and use of the wines. In most red wine-making processes, it is preferred that the maceration process is accompanied by the fermentation process, as increase in the alcohol content favours the intensification of the extraction process. For this reason, both processes are combined in a single technological operation known as maceration-fermentation. The largest amount of polyphenolic compounds of wine, anthocyanins and tannins comes from the solid parts of the grapes - the skins and seeds, and these have a decisive influence on the phenolic character of wines. Maceration is a fractional extraction which leads to the dissolution of the useful components of the grapes, which give the flavour, colour and taste typical of red wine. The aim of this research was to analyse the effect of different techniques of maceration fermentation on the phenolic composition of red wines obtained from Merlot, Pinot noir and Cabernet Sauvignon grape varieties in Copou-Iasi vineyard compared to red wines obtained from the same varieties in Murfaltar vineyard, located in the northeast and south of Romania, respectively. Wines obtained by maceration-fermentation in rotating tanks have higher values of the Folin-Ciocâlteu index (wines obtained from Pinot noir) in contrast to those obtained by the classical maceration-fermentation technique (wines obtained from Merlot and Cabernet Sauvignon).

Abstract:
This research analyzes the exports of wine companies in the Valle de Guadalupe region in the State of Baja California, Mexico. The objective is to determine the factors that induce strategic decision making to achieve a high-performance level of productive capacity. The hypothesis suggests that production, technological innovation, and competitiveness are the factors that favor the exports of these wine companies. For the statistical analysis, Partial Least Squares structural equation modeling (PLS-SEM) is used, including the evaluation of the out-of-sample predictive power by means of PLS predict. The methodology used includes a qualitative analysis of the current situation on the subject and a quantitative study of data obtained by applying a 41-item instrument to ninety-two companies. The main findings show that the variable that presents a higher degree of association is competitiveness and the variable that presents a lower degree is production. Another finding is that there is a need to strengthen collaborative projects with a Cluster Approach, in which the collaboration network between these companies, government agencies, wine associations and educational institutions must be actively involved. The main strategies proposed are three: the first in relation to competitiveness is to improve operational planning to increase productivity. The second is to achieve a more competitive price by purchasing supplies collaboratively between companies; the existing common bond and business cooperation will allow exports to increase. The third is to manage a greater participation of the government, in terms of financing and support, investment in highway infrastructure, reduction of taxes on this item and the sustainable administration of the State's water resources.

ENGLISH ABSTRACT: In the highly competitive international wine markets, effective procurement of raw material could prove the difference between success or failure for a wine company. Therefore the researcher embarked on this study to create a model that will assist procurement decision makers in the South African wine industry in the strategic procurement of raw material. In order to create a model for procurement of raw material in the South African wine industry, qualitative research was conducted that included a study of literature, available material, views from experts as well as a content analysis from sample interviews. Procurement officials need to ensure that marketing forecasts are aligned with contracted procurement volumes. Cost, quality and availability should be tightly managed to minimise losses due to unallocated inventory or lack of raw material with sufficient quality or quantity to serve a marketing need. Suppliers should be prioritised in terms of strategic importance and procurement decision-makers should be crystal clear on which strategy to pursue with each quality segment and supplier in order to obtain the right quantity at the desired quantity and most economical price. Procurement decision makers need to evaluate the procurement and market environment for opportunities and threats that might impact on their ability to procure raw material from their supply base, and put measures in place to take control of possible effects of those uncertainties. This includes differentiating between grape procurement and wine procurement to leverage the advantages from both. Procurement officials must establish an action plan to limit the risk of cost, availability and quality by engaging and investing in trusting, loyal relationships with proficient suppliers with capacity. The procurement function should operate in a professional manner, building a track record of pro-active procurement and focus on loyal supplier relationships.
AFRIKAANSE OPSOMMING: In die hoogs kompeterende internasionale wynmarkte kan effektiewe aankope van rou-materiaal die verskil beteken tussen sukses of mislukking vir 'n wynmaatskappy. Daarom het die navorser begin met hierdie studie om 'n model te skep wat besluitnemers van aankope kan bystaan met die strategiese aankoop van roumateriaal in die Suid-Afrikaanse wynbedryf. Om 'n model te skep vir die aankoop van roumateriaal in die Suid-Afrikaanse wynbedryf is kwalitatiewe navorsing gedoen, wat 'n literatuurstudie insluit, sowel as 'n studie van beskikbare materiaal, sienings van kenners en 'n inhoudsanalise van steekproefonderhoude. Aankoopsbeamptes moet verseker dat bemarkingsvooruitskattings en gekontrakteerde aankoopvolumes ooreenstem. Koste, kwaliteit en beskikbaarheid moet streng bestuur word om verliese te beperk wat kan ontstaan deur ongeallokeerde voorraad of 'n tekort aan roumateriaal met genoegsame kwaliteit of hoeveelheid om 'n bemarkingsbehoefte te bevredig. Verskaffers moet prioritiseer word in terme van strategiese belangrikheid en aankoop-besluitnemers moet kristalhelder dink oor watter strategie om te volg met elke kwaliteitssegment en verskaffer, sodat die regte hoeveelheid en volume teen die mees ekonomiese prys aangekoop word. Aankoopbesluitnemers moet die aankoop- en markomgewing evalueer vir geleenthede en bedreigings wat 'n invloed kan hê op hul vermoë om roumateriaal van hul verskaffingskorps aan te koop, en moet maatreëls in plek stel om beheer te neem oor die moontlike effek van daardie onsekerhede. Maatreëls sluit in die differensiasie tussen druifaankope en wynaankope om die voordele van elk maksimaal te benut. Aankoopsbeamptes moet 'n aksieplan vestig om die risiko van koste, beskikbaarheid en kwaliteit te beperk deur in verbintenisse te belê met lojale vertrouensverhoudings met vaardige verkaffers met kapasiteit. Die aankoopsfunksie moet op 'n professionele manier optree, om 'n beeld van pro-aktiewe aankope te bou en 'n fokus op lojale verskafferverhoudings te vestig.

Abstract:
Natural corks have long been used as wine closures. However, they are associated with causing multiple adverse effects to the wine they are attempting to preserve. Alternative closures such as synthetic corks and screw caps were developed in order to reduce and/or eliminate these problems. However, the major cause of concern regarding these closures is of consumers' acceptance. The effect of how three types of closures (Natural Cork, Synthetic Cork and Screw Cap) affected wine consumers' perceptions of the quality of wine was examined in this study. This project was divided into two experiments. The first experiment determined if frequent wine consumers could detect sensorial differences between the three closure types. The second experiment ascertained if and how regular wine consumers' perceptions were altered based on the type of closure with which the wine samples were bottled. It was determined that the wine consumers could not significantly detect a difference between any of the three closure type samples based only on sensory stimuli. The results from the second experiment found for the Chardonnay samples, the knowledge that the wine samples came from a natural cork or a synthetic cork did not significantly affect the liking, quality or purchase intent scores. However, when the panelists knew that the sample was bottled with a screw cap, they thought it was of lower quality, were less willing to buy a wine like the sample and they lowered the price they were willing to pay. For the Merlot samples, knowledge that the sample came from a natural cork caused the wine consumers to significantly increase both their opinions of the quality of the wine and the amount they were willing to pay for the wine. When they knew that the sample was bottled with a screw cap, they reduced the price they would pay for the wine.

Abstract:
Recycling, which includes composting, is the current rage. Almost every community in North America has established some kind of recycling program in the past few years. This chapter focuses on the science and technologies that are involved in recycling programs and explores what is needed to make these programs successful. This section describes the part of recycling that is associated with blue-box or streetside programs. It includes paper, cardboard, metal, aluminum, and plastics; composting is described in the next section. A successful waste recycling program relies on more than a systematic application of equipment and other resources. It also depends very significantly on attitude. It is vital that everyone participate. To achieve a meaningful level of participation, some degree of legislative guidance may be necessary. In fact, studies have shown that mandatory recycling programs are much more effective than those run on a voluntary basis (Platt et al., 1991). Legislation or bylaws can also be used to • stipulate that soft-drink, beer, wine, and other bottles be Reused • require the use of recycled material in manufacturing new products • avoid excessive packaging • reduce tipping fees for recyclable or compostable materials brought to designated drop-off sites • set higher tipping fees for waste from which recyclables have not been removed • ban the landfilling of certain substances, such as yard wastes Public education is an indispensable part of an integrated waste management system. First, the public must be informed of the details that involve them: what days pickups are made, how to obtain recycle containers, what materials can be recycled, how they are to be sorted, and so on. This information can be disseminated by flyers, newsletters, ads in the local paper, features on local television channels, and telephone hot lines. Second, an ethic of conservation should be instilled so that people will want to participate in three Rs programs. Methods of achieving this objective include videos and slide shows at schools, posters, buttons, and awards to businesses and groups that make outstanding contributions to recycling.

Abstract:
A single, integrated database to store inputs from multiple, and multidisciplinary wayside systems is a pre-requisite for cross-correlation of data, and the development of intelligent algorithms to determine alarm levels and automate decision making. Australian rail operators run on three track gauges, operate a mix of American, European and uniquely Australian rolling stock, and lack a unified set of interchange standards, making the development of operational and condition monitoring rules a complex task. Over the years, Wayside Equipment vendors have adopted different database architectures and data structures for their proprietary systems. Recognizing the need for an industry-wide standard, Pacific National and Track Owners in Australia have initiated a project to develop the architecture for an integrated, open database to capture and store data feeds from multiple wayside systems, from different suppliers. This paper describes the objectives, constraints, challenges and projected benefits of the project for the track owner and the rail operator, and the planned implementation of an integrated condition monitoring database in the Australian rail environment.

Abstract:
In a steam power plant, steam from the steam turbine is condensed in a water cooled or air cooled condenser that operates under vacuum. The condensing capacity of the condenser is impaired by the presence of air. Air leaks into the condenser from flanged connections, turbine seals, valves and other equipment connected to the condenser. The air tends to collect in the condenser and impact its condensing capability. This trapped air has to be continuously evacuated to preserve the condensing capacity of the condenser. The air can be evacuated from the condenser using the steam jet air ejector system or the vacuum pump system. The vacuum pump is driven by an electrical motor. The steam jet air ejector is driven by motive steam. In certain low suction pressure applications, a hybrid system consisting of a steam jet air ejector and vacuum pump or a three stage ejector system is used for evacuating the air from the condenser. The evacuation packages perform two distinct services namely hogging and holding. During startup, or hogging operation, the evacuation system removes air from the steam space of the condenser and steam turbine. The pressure in the steam space is reduced from atmospheric pressure to typically 10.0” HgA or a pressure specified by the steam turbine supplier in about 30 minutes. During normal or “holding operation” with the steam turbine in service, the evacuation system removes a specified amount of air from the condenser. The suitability of vacuum pump or steam jet air ejector systems for a given application depends on the availability of motive steam during startup, the costs associated with the usage of steam or electricity and the preferences of the end user. Each system has its advantages and disadvantages. In each case, there are numerous design details that must be addressed to ensure that the selected system meets the evacuation needs for the condenser. This paper examines the various configurations of evacuation systems and discusses their suitability for the wide ranging operating scenarios in the condenser. A broad background on the design and operation of the evacuation system is included to assist the end user in making the proper selection of the evacuation system.

Abstract:
Increased research into the chemistry, physics and material science of hydrogen cycling compounds has led to the rapid growth of solid-phase hydrogen-storage options. The operating conditions of these new options span a wide range: system temperature can be as low as 70K or over 600K, system pressure varies from less than 100kPa to 35MPa, and heat loads can be moderate or can be measured in megawatts. While the intense focus placed on storage materials has been appropriate, there is also a need for research in engineering, specifically in containment, heat transfer, and controls. The DOE’s recently proposed engineering center of expertise underscores the growing understanding that engineering research will play a role in the success of advanced hydrogen storage systems. Engineering a hydrogen system will minimally require containment of the storage media and control of the hydrogenation and dehydrogenation processes, but an elegant system design will compensate for the storage media’s weaker aspects and capitalize on its strengths. To achieve such a complete solution, the storage tank must be designed to work with the media, the vehicle packaging, the power-plant, and the power-plant’s control system. In some cases there are synergies available that increase the efficiency of both subsystems simultaneously. In addition, system designers will need to make the hard choices needed to convert a technically feasible concept into a commercially successful product. Materials cost, assembly cost, and end of life costs will all shape the final design of a viable hydrogen storage system. Once again there is a critical role for engineering research, in this case into lower cost and higher performance engineering materials. Each form of hydrogen storage has its own, unique, challenges and opportunities for the system designer. These differing requirements stem directly from the properties of the storage media. Aside from physical containment of compressed or liquefied hydrogen, most storage media can be assigned to one of four major categories, chemical storage, metal hydrides, complex hydrides, or physisorption. Specific needs of each technology are discussed below. Physisorption systems currently operate at 77K with very fast kinetics and good gravimetric capacity; and as such, special engineering challenges center on controlling heat transfer. Excellent MLVSI is available, its cost is high and it is not readily applied to complex shape in a mass manufacture setting. Additionally, while the heat of adsorption on most physisorbents is a relatively modest 6–10kJ/mol H2, this heat must be moved up a 200K gradient. Physisorpion systems are also challenged on density. Consequently, methods for reducing the cost of producing and assembling compact, high-quality insulation, tank design to minimize heat transfer while maintaining manufacturability, improved methods of heat transfer to and from the storage media, and controls to optimize filling are areas of profitable research. It may be noted that the first two areas would also contribute to improvement of liquid hydrogen tanks. Metal hydrides are currently nearest application in the form of high pressure metal hydride tanks because of their reduced volume relative to compressed gas tanks of the same capacity and pressure. These systems typically use simple pressure controls, and have enthalpies of roughly 20kJ/mol H2 and plateau pressures of at most a few MPa. During filling, temperatures must be high enough to ensure fast kinetics, but kept low enough that the thermodynamically set plateau pressure is well below the filling pressure. To accomplish this balance the heat transfer system must handle on the order of 300kW during the 5 minute fill of a 10kg tank. These systems are also challenged on mass and the cost of the media. High value areas for research include: heat transfer inside a 35MPa rated pressure vessel, light and strong tank construction materials with reduced cost, and metals or other materials that do not embrittle in the presence of high pressure hydrogen when operated below ∼400K. The latter two topics would also have a beneficial impact on compressed gas hydrogen storage systems, the current “system to beat”. Complex hydrides frequently have high hydrogen capacity but also an enthalpy of adsorption >30kJ/mol H2, a hydrogen release temperature >370K, and in many cases multiple steps of adsorption/desorption with slow kinetics in at least one of the steps. Most complex hydrides are thermal insulators in the hydrided form. From an engineering perspective, improved methods and designs for cost effective heat transfer to the storage media in a 5 to 10MPa vessel is of significant interest, as are materials that resist embrittlement at pressures below 10MPa and temperatures below 500K. Chemical hydrides produce heat when releasing hydrogen; in some systems this can be managed with air cooling of the reactor, but in other systems that may not be possible. In general, chemical hydrides must be removed from the vehicle and regenerated off-board. They are challenged on durability and recycling energy. Engineering research of interest in these systems centers around maintaining the spent fuel in a state suitable for rapid removal while minimizing system mass, and on developing highly efficient recycling plant designs that make the most of heat from exothermic steps. While the designs of each category of storage tank will differ with the material properties, two common engineering research thrusts stand out, heat transfer and structural materials. In addition, control strategies are important to all advanced storage systems, though they will vary significantly from system to system. Chemical systems need controls primarily to match hydrogen supply to power-plant demand, including shut down. High pressure metal hydride systems will need control during filling to maintain an appropriately low plateau pressure. Complex hydrides will need control for optimal filling and release of hydrogen from materials with multi-step reactions. Even the relatively simple compressed-gas tanks require control strategies during refill. Heat transfer systems will modulate performance and directly impact cost. While issues such as thermal conductivity may not be as great as anticipated, the heat transfer system still impacts gravimetric efficiency, volumetric efficiency and cost. These are three key factors to commercial viability, so any research that improves performance or reduces cost is important. Recent work in the DOE FreedomCAR program indicates that some 14% of the system mass may be attributed to heat transfer in complex hydride systems. If this system is made to withstand 100 bar at 450K the material cost will be a meaningful portion of the total tank cost. Improvements to the basic shell and tube structures that can reduce the total mass of heat transfer equipment while maintaining good global and local temperature control are needed. Reducing the mass and cost of the materials of construction would also benefit all systems. Much has been made of the need to reduce the cost of carbon fiber in compressed tanks and new processes are being investigated. Further progress is likely to benefit any composite tank, not just compressed gas tanks. In a like fashion, all tanks have metal parts. Today those parts are made from expensive alloys, such as A286. If other structural materials could be proven suitable for tank construction there would be a direct cost benefit to all tank systems. Finally there is a need to match the system to the storage material and the power-plant. Recent work has shown there are strong effects of material properties on system performance, not only because of the material, but also because the material properties drive the tank design to be more or less efficient. Filling of a hydride tank provides an excellent example. A five minute or less fill time is desirable. Hydrogen will be supplied as a gas, perhaps at a fixed pressure and temperature. The kinetics of the hydride will dictate how fast hydrogen can be absorbed, and the thermodynamics will determine if hydrogen can be absorbed at all; both properties are temperature dependent. The temperature will depend on how fast heat is generated by absorption and how fast heat can be added or removed by the system. If the design system and material properties are not both well suited to this filling scenario the actual amount of hydrogen stored could be significantly less than the capacity of the system. Controls may play an important role as well, by altering the coolant temperature and flow, and the gas temperature and pressure, a better fill is likely. Similar strategies have already been demonstrated for compressed gas systems. Matching system capabilities to power-plant needs is also important. Supplying the demanded fuel in transients and start up are obvious requirements that both the tank system and material must be design to meet. But there are opportunities too. If the power-plant heat can be used to release hydrogen, then the efficiency of vehicle increases greatly. This efficiency comes not only from preventing hydrogen losses from supplying heat to the media, but also from the power-plant cooling that occurs. To reap this benefit, it will be important to have elegant control strategies that avoid unwanted feedback between the power-plant and the fuel system. Hydrogen fueled vehicles are making tremendous strides, as can be seen by the number and increasing market readiness of vehicles in technology validation programs. Research that improves the effectiveness and reduces the costs of heat transfer systems, tank construction materials, and control systems will play a key role in preparing advanced hydrogen storage systems to be a part of this transportation revolution.
