AbstractThe development of a hydrogen infrastructure has been identified as a key barrier to implementing hydrogen as for a future transportation fuel. Several recent studies of hydrogen infrastructure have assessed near-term and long-term alternatives for hydrogen supply [1-2]. In this paper, we discuss how advances in material science related to hydrogen storage could change how a future hydrogen infrastructure is designed. Using a simplified engineering/economic model for hydrogen infrastructure design and cost, we explore some potential impacts of advances in storage materials, in terms of system design, cost, energy use, and greenhouse gas emissions. We find that the characteristics of hydrogen storage play a major role in the design, cost, energy use, and CO2 emissions of hydrogen supply infrastructure.

Load Leveling

As a method for simultaneously increasing efficiency of energy use and stability of energy supply in commercial buildings, we have proposed Totalized Hydrogen Energy Utilization System (THEUS) that uses hydrogen as a high potential for energy carrier. The hydrogen storage method used by this system adopts metal hydride that excels in volumetric storage density. In this paper, as the model case for electric power load leveling operation, the optimum design and optimum operation method for multiple metal hydride tanks are described with a mathematical model which can simulate operation of the metal hydride tank and experimental equipment. As a result, the combination of tank specifications and operating conditions that produce the effective simultaneous utilization of 1) hydrogen, 2) metal hydride and 3) heat are identified. Furthermore, an operating method to make the most of the metal hydride tank flexibility with respect to tank selection is determined.

Recent Advances

An overview of recent advances in hydrogen storage is presented in this review. The main focus is on metal hydrides, liquid-phase hydrogen storage material, alkaline earth metal NC/polymer composites and lithium borohydride ammoniate. Boron-nitrogen-based liquid-phase hydrogen storage material is a liquid under ambient conditions, air- and moisture-stable, recyclable and releases H2controllably and cleanly. It is not a solid material. It is easy storage and transport. The development of a liquid-phase hydrogen storage material has the potential to take advantage of the existing liquid-based distribution infrastructure. An air-stable composite material that consists of metallic Mg nanocrystals (NCs) in a gas-barrier polymer matrix that enables both the storage of a high density of hydrogen and rapid kinetics (loading in <30 min at 200°C). Moreover, nanostructuring of Mg provides rapid storage kinetics without using expensive heavy-metal catalysts. The Co-catalyzed lithium borohydride ammoniate, Li(NH3)4/3BH4 releases 17.8 wt% of hydrogen in the temperature range of 135 to 250 °C in a closed vessel. This is the maximum amount of dehydrogenation in all reports. These will reduce economy cost of the global transition from fossil fuels to hydrogen energy.

Processing Techniques

Abstract For annealing, brazing or sintering, furnace atmospheres help ensure that metals thermal processors obtain the results they need. Hydrogen-containing atmospheres are used to protect surfaces from oxidation, and to ensure satisfactory thermal processing results. Hydrogen-containing atmospheres make thermal processing more forgiving because the hydrogen improves heat conduction and actively cleans heated surfaces – reducing oxides and destroying surface impurities. For powder based fabrication such as P/M, MIM or binder-jet metal AM, the use of a hydrogen-containing thermal processing atmosphere ensures the highest possible density of the sintered parts without necessitating the use of post-processing techniques. Users of pure hydrogen or hydrogen-containing gas blend atmospheres often struggle with hydrogen supply options. Hydrogen storage may create compliance problems due to its flammability and high energy content. Hydrogen generation enables hydrogen use without hydrogen storage issues. Deployment of hydrogen generation can ease the addition of thermal processing atmospheres to new and existing processing facilities.

The Impact

Nowadays energy storage seems to be a vital point in any new energy paradigm. It has become an important and strategic issue, to ensure the energetic sufficiency of humanity. Indeed, hydrogen storage in solids has been proved and revealed as clean and efficient energy storage. Moreover, it can be thought as a seriously considered solution to enable renewable energy to be a part of our quotidian life. To achieve storing hydrogen in solid form, the present study aimed to concepts and simulates a solid-state hydrogen storage reactor (tank). An investigation of the parameters influencing the hydrogen storage performance is carried out. Meanwhile, to understand the physical phenomenon taking place during the storage of hydrogen, a 2D numerical modelling for a metal hydrides-based in hydrogen reactor is presented. A strong coupling between energy balance, kinetic law, as well as a mass momentum balance at sorbent bed temperature under a non-uniform pressure was resolved based on finite element method. The temporal evolutions of pressure, the raising temperature in the bed during the hydriding process as well as the impact of the hydrogen supply pressure within the tank are analysed and validated by comparison with the experimental work in literature, a good agreement is obtained. From an industrial point of view, this study can be used to design and manufacture an optimal solid-state hydrogen storage reactor.

Conventional fuels such as oil, natural gas, and coal have historically provided reasonable financial returns on investment as well as energy returned on energy invested (EROEI), despite the fact that continuous financial and energy inputs are required to use these fuels. Besides EROEI, the energy intensity ratio (EIR) is another measure for energy use and economics. The EIR is the ratio of energy bought per dollar to the energy it takes to make a dollar in the economy. In this case we are considering the cost of petroleum per barrel, and therefore we are discussing EIRp or EIR of oil based upon price. The EIRp is related to historical economical data and conclusions will be drawn about the value of EIRp as an economic indicator. Then, EIRp will be used as a tool to demonstrate the value of shifting energy resources from petroleum to alternatives, specifically for transportation and petrochemicals. The considerations for modern economic conditions as they compare to historical economic conditions will be explained, and the viability of policy and alternative technological transportation scenarios will be described in terms of EIRp and its relationship to vehicle miles travelled.

Magnitude Scaling

A parametric estimation algorithm is described for system design criteria selection in Ground Source Heat Pump (GSHP) Heating, Ventilation and Air Conditioning (HVAC) applications requiring dissipation of annual cycle excess thermal energy to the air, i.e., a hybrid mode. The model applies a combination of order-of-magnitude scaling (OMS) and classical non-dimensional flow and heat transfer methods. The objective is to develop a simplified parametric range display for selection of design values. Application requirements and constraints map into the solution space for specific design value selections. The annual thermal budget cycle is configured to time-phase the earth-stored excess energy from the cooling season for dissipation in the heating season using water to ambient forced-air (fan-coil) cooling. Estimators for an application are developed for the quantity, spacing and depth of well bores and the loop flow rate range based on Reynolds number and Nusselt number correlations for water and earth thermal properties. A case study application in two parts is described. The GSHP system uses a common working fluid (water) in a closed loop serving all 70 zones to furnish heating, cooling, domestic water heating, and exterior walkway deicing for an 80,000 sq. ft. area, 54 apartment, senior, center in Dallas Texas, USA. In 1999, the initial Phase I facility of 55,000 sq. ft. area was occupied using the full capacity flow system design without the dissipation coolers. In 2004 the coolers were included with the expansion to full occupancy. Design parameter values, operating experience, energy use, and the rationale for the demonstrated compatibility of the single solution for essentially two applications are described.
