Hydrogen Production Technologies
Biological organisms can produce hydrogen directly from sunlight and water. In addition, semiconductor-based systems similar to photovoltaics (PV) can be used for hydrogen production. Hydrogen can also be produced indirectly via thermal processing of biomass or fossil fuels. Global environmental concerns are leading to the development of advanced processes to integrate sequestration with known reforming, gasification, and partial oxidation technologies for carbonaceous fuels. These production technologies have the potential to produce essentially unlimited quantities of hydrogen in a sustainable manner.

Hydrogen Storage Technologies
Storage of hydrogen is an important area for cooperative research and development, particularly when considering transportation as a major user and taking the need for efficient energy storage for intermittent renewable power systems into account. Although compressed gas and liquid hydrogen storage systems have been used in vehicle demonstrations worldwide, issues of safety, capacity, and energy consumption have resulted in a broadening of the storage possibilities to include metal hydrides and carbon nano-structures. Stationary storage systems that are highly efficient and that have quick response times will be important for incorporating large amounts of intermittent PV and wind into the grid as base-load power.

Hydrogen Utilization Technologies
Achieving the vast potential benefits of a hydrogen system requires careful integration of production, storage and end-use components with minimized cost and maximized efficiency, and a strong understanding of environmental impacts and opportunities. System models combined with detailed life cycle assessments provide the platform for standardized comparisons of energy systems for specific applications. Individual component models form the framework by which these system designs can be formulated and evaluated.
