6 FAQs about [Ten times hydrogen energy storage]

Can a large-capacity hydrogen storage system meet the demand for energy storage?

For instance, if the portion of electricity with rapid fluctuations and the user’s peak load are relatively small, a larger-capacity CB could serve as the base load for energy storage, while a smaller-capacity hydrogen storage system could meet the demand for rapid-response energy storage.

What is China's 'hydrogen into ten thousand homes' project?

This project, part of China’s “Hydrogen Into Ten Thousand Homes” initiative, serves as a demonstration of large-scale hydrogen energy storage and its integration into existing systems. This initiative aligns with broader policy goals of reducing carbon emissions and increasing renewable energy utilization.

What is hydrogen energy storage?

Hydrogen energy storage utilizes electrolytic cells and fuel cells for the conversion between electricity and hydrogen energy. For hydrogen production, the proton exchange membrane electrolysis cell (PEMEC) is renowned for its high electrolysis efficiency (58 %–70 % ) and economic advantages .

How to calculate RTE and exergy efficiency of hydrogen energy storage system?

The round-trip energy efficiency (RTE) and exergy efficiency of the hydrogen energy storage system are defined as follows: (21) χ h = η ex,h = W f + W e,H2 W e + W c,H2 where We,H2 is the power generated by the H2 expander of the SOFC subsystem, kW; Wc,H2 is the power input of the H2 compressor of the PEMEC subsystem, kW.

Can energy storage combine CB and hydrogen?

This study proposes an integrated energy storage system combining CB with hydrogen energy storage. During the energy storage process, CB acts as the base load to absorb large-scale surplus electricity, while PEMEC serves as the regulating load, flexibly absorbing fluctuating power.

Why is hydrogen storage so expensive?

This is attributed to a higher pressure ratio during the discharge phase and a higher operating temperature range for the turbines. Additionally, the cost of heat exchangers of hydrogen storage in the coupled system has risen, as additional heat exchangers are required for thermal exchange between hydrogen and molten salt.
