100% renewable targets will require power storage to manage flows on the net
Electrolysers utilise these intermittent power flows to produce H2 gas from water
H2 gas can be stored in large quantities underground and transported via existing gas pipelines
H2 vehicles recharge faster and are more durable than battery powered transport
Growing H2 demand in industrial processes will reduce costs and increase supply

Twelve European leading organizations have announced the launch of the HyUnder project, co-financed by the Fuel Cell and Hydrogen Joint Undertaking.

A kick-off meeting was held in Brussels on June 20th to launch the project HyUnder: “Assessment of the potential for large scale storage of renewable electricity through underground hydrogen storage in different regions of Europe”

HyUnder will provide the first complete assessment of the potentials for large scale storage of fluctuating renewable electricity in underground salt caverns for hydrogen, with specific focus on using synergies with its application as transport fuel and other markets.

The project will run for a period of two years and will develop 6 case studies across Europe and an EU Implementation Plan on large scale underground hydrogen storage, with particular focus on salt caverns.
