www.erreduegas.it

Excess renewable energy produced by sources with a

high variation output (e.g. wind turbines) is used for

hydrogen generation through water electrolysis.

H2+CO2 (e.g. from biogas) are turned into methane which is

injected into the gas grid as “synthetic natural gas”(SNG).

Hydrogen for Energy Storage– P2G

There is a new way to store energy within grids with a

great percentage of renewable energy:

it’s called “power to gas”

This gas can be stored and distributed through the existing

infrastructure.

The mutual convertibility of electricity and gas enebles a

smoothing of the electrical supply.
