Tóm tắt

Low-carbon hydrogen is anticipated to be a key element of economy-wide decarbonization pathways. Here we employ a multisector energy system model of the contiguous United States to study competition among low-carbon hydrogen production options and the interplay between the electricity and hydrogen sectors in a net-zero energy system. When hydrogen storage is available without constraints and electrolyzers are grid-connected, they account for most hydrogen production, while providing demand-side flexibility to the electricity system. This decreases battery storage deployment to achieve similar shares of variable renewable energy (VRE) in the power system. When electrolyzers are not grid-connected but rely on islanded VRE power to produce "green" H
