Expert Views on the Role of Energy Storage for the German Energiewende Final report Alexander von Humboldt Foundation German Chancellor Fellowship "Energy Storage Technology and Large-scale Integration of Renewable Energy" Eric Borden 1 Abstract: As the German "Energiewende," or energy transformation, propels renewables in the power sector to increasing penetration rates, research over . The energy required to liquefy hydrogen for storage in an ideal Linde thermodynamic cycle has been calculated to be 11.88 MJ/H 2-kg (Leung et al., 2004), about 64% higher than the energy required for high-pressure hydrogen gas compression. Different business models and applications favour different technologies. In sum, integrating energy storage technologies into our electric grid infrastructure promises a fundamental reconfiguration of how our nation produces and uses electricity with the hope of a more reliable, resilient, and cost-effective grid. It is noted that increasing the hydrogen storage pressure increases the volumetric storage density (H2-kg/m3), but the overall energy 2 ENERGY STORAGE TODAY In 2017, the United States generated 4 billion megawatt-hours (MWh) of electricity,5 but only had 431 MWh of electricity storage available.6 Pumped-storage hydropower (PSH) is by far the most popular form of energy storage in the United States, where it accounts for 95 percent of utility-scale energy storage. 2.
