Technical, financial and operational feasibility of injecting hydrogen gas, generated from electrolysis fed from excess renewables, into the UK gas networks.

ITM Power were lead company for this project which investigated the technical, financial and operational feasibility of injecting hydrogen gas, generated from electrolysis fed from excess renewables, into the UK gas networks.

The project included preliminary logistical research, system research, and creation of a generation model with the simulation of hydrogen production at a single wind farm.

The project looked at providing a mean to exploit periods in the electricity generation cycle during which there is excessive supply on the UK power network which cannot currently be used effectively.

In the case of renewable energy, periods of low demand but high wind speeds result in large payments (under curtailment schemes) being made to wind farm operators. As part of the project, research examined the feasibility of installing strategically located electrolysers to absorb this spare capacity by generating a substantial volume of hydrogen
