Smart Energy Hydrogen Storage

Is hydrogen storage a viable alternative to grid management and balancing?

Researchers have been working on innovative technologies and storage alternatives for grid management and balancing, and there is a growing interest hydrogen storage. Because hydrogen can be stored, it presents a feasible option to balance grid fluctuations expected from renewable energy sources such as wind or solar.

Can hydrogen be stored?

Because hydrogen can be stored, it presents a feasible option to balance grid fluctuations expected from renewable energy sources such as wind or solar. Thanks to reversible fuel cell technology, water can be split through electrolysis to produce hydrogen, as well as convert hydrogen back to electricity.

Why is hydrogen storage important?

Promising solutions, such as hydrogen storage, can counteract the intermittency of solar and wind energy and optimize the use of stored energy when the wind doesn’t blow and the sun doesn’t shine. Certification and testing play a pivotal role to ensure hydrogen storage is carried out safely.

How does a hydrogen storage system work?

The system will use battery storage to optimise operations (Renews, 2021). In another example, the Delta Green project in France produces and stores green hydrogen during periods of high renewable energy production, and then converts the hydrogen back into electricity during peak-load hours (Construction21 France, 2018).

Should hydrogen energy storage & P2P be viewed as competitors?

Hydrogen energy storage and P2P routes are under R&D to increase efficiency and lower costs in the coming years. Hydrogen storage and batteries should not be viewed as competitors for providing flexibility to the power system; instead, they complement each other in important ways.

What is a green hydrogen demonstration project?

It is the first comprehensive green hydrogen demonstration project on an island in China. The project promotes the clean energy consumption and power flow optimisation of power grids on the island and achieves 100% consumption of clean energy and zero-carbon energy supply throughout the process.
