Making the Case for Hydrogen in a Zero-Carbon Economy

MIT Energy Initiative8 minEnglish

Why watch it?

An eight-minute audio article from the MIT Energy Initiative summarises a study by MITEI researchers Emre Gençer and Drake D Hernandez on California's power system. According to the description, the study finds that electricity generated from hydrogen can be a cost-competitive alternative to fossil-fuelled peaker plants and lithium-ion battery arrays for backing up solar and wind. A compact entry point on long-duration storage. The result is specific to California, and its assumptions and figures have not been independently checked.

This introduction is based on the video’s YouTube description and catalogue details.

What you will learn

The viewer can compare the cost competitiveness of hydrogen-to-power with peaker plants and lithium-ion batteries as backup for renewables.

IPEC Expert Opinion

Doğukan Ünal · Chemist, hydrogen technology expert ·

According to the description, the MITEI study finds hydrogen-to-power cost-competitive with peaker plants and lithium-ion batteries in the California system. The round-trip efficiency of a chain of electrolyser, storage and turbine or fuel cell is typically 30–40%; hydrogen therefore cannot compete with batteries for daily balancing; its chance lies in long-duration, infrequent needs. The finding is specific to one region and its cost assumptions.
