ITM Power has provided an update on the ‘groundbreaking’ Thüga Power-to-Gas energy storage project in Germany, following its first full year of successful operation.

Thüga reported that the system has been declared ‘technically able to participate in the secondary power market’.

This means, ITM Power explains, that the electrolyser is technically capable of offering grid balancing services – which increases the economic viability of the technology.

The system has now undergone and passed its first annual re-assessment by TUEV Hessen. The electrolyser system has met every aspect of its specification including efficiency, remote control functionality and response time. The data for the plant has been shared with the partners under the project partnering agreement.

The 300kW plant is the first and only rapid response PEM electrolyser plant to be injecting hydrogen into the German gas network; first injection was on 26th November 2013.

Dr. Graham Cooley, CEO of ITM Power commented, “ITM Power is delighted to have supplied the first and only rapid response PEM electrolyser plant to be injecting hydrogen into the German gas network. The first anniversary of injection demonstrates that there is a working solution to the problem of storing and managing renewable energy.”

Lighthouse project

In addition to technical success, the plant has also served as a lighthouse project attracting more than 300 visitors from multiple sectors around the world, as well as significant public domain interest.

Crucially, it has enabled both ITM Power and the members of the Thüga Group to demonstrate the principle of PEM Power-to-Gas in action.

Phil Doran, Managing Director of ITM Power GMBH, added, “The project continues to prove the technical capability of ITM Power’s P2G product and the value of our cooperation with Germany’s leading association of civil utilities, the Thüga Group. Our continued involvement with the project has yielded substantial benefits to us all.”
