Achieving gigawatt-scale green hydrogen production and seasonal storage at industrial locations across the U.S

Abstract: Tightly coupling Gigawatt-scale wind- and solar-sourced H2 with industry depends on the ability to store and deliver otherwise-curtailed H2 during times of shortages. Thousands of tonnes of H2 will require storage in regions where subsurface storage is scarce, which may only be possible using liquid organic H2 carriers. Herein, we evaluate the scale and operation of aboveground systems storing and delivering otherwise-curtailed H2 using TOL/MCH at 50,052 locations in the United States suitable for Gigawatt-scale wind- and solar-powered electrolyzer systems. Modeling results suggest that the levelized cost of storage is highly spatially heterogeneous, with minor impact on the cost of H2 in the Midwest, and potentially significant impact in areas with emerging H2 economies such as Central California and the Southeast. While TOL/MCH may be the cheapest aboveground bulk storage solution evaluated, upfront capital costs, modest energy efficiency, reliance on critical materials, and greenhouse gas emissions from heating remain concerns.
