The Energy Storage Credit adds a new provision to the energy investment tax credit for energy storage, including hydrogen storage, available through 2025 before a transition to the Clean Energy Investment Credit.
[pdf] Chemical storage could offer high storage performance due to the high storage densities. For example, supercritical hydrogen at 30 °C and 500 bar only has a density of 15.0 mol/L while has a hydrogen density of 49.5 mol H2/L methanol and saturated at 30 °C and 7 bar has a density of 42.1 mol H2/L dimethyl ether. Researchers at EPFL and Kyoto University have created a stable hydrogen-rich liquid formed by mixing two simple chemicals. This breakthrough could make hydrogen storage easier, safer, and more efficient at room temperature.
[pdf] It also quantitatively assesses the market potential of solid-state hydrogen storage across four major application scenarios: on-board hydrogen storage, hydrogen refueling stations, backup power supplies, and power grid peak shaving.
