'H2@Scale' - An Emerging Cross-Sector Opportunity in the USA

The 'H2@Scale' concept, led by the U.S. Department of Energy (DOE) and the U.S. National Laboratory system, lays a framework for the potential wide-scale production and utilization of hydrogen to address key issues such as enabling grid resiliency, energy security, and cross-sectoral emissions reductions. The premise of the H2@Scale concept is that, in an electricity grid with increasing penetrations of inflexible generation, such as renewables, water splitting technologies can be used to generate hydrogen as an energy carrier when power generation exceeds load, rather than curtail those resources. That hydrogen can then be distributed and used as a feedstock or fuel in industrial and transportation sectors. This integrates these sectors more closely with the electricity grid, and reduces reliance on fossil fuels in end use applications across multiple market sectors.
