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

On June 28th, 2016 a EU Parliament Breakfast Debate at the European Parliament hosted by the German MEP Jo Leinen and organized by Hydrogen Europe featured Siemens view on  “Power2Hydrogen – The Missing Link of the Energy Transition”. Siemens illustrated their project of energy storage through hydrogen that is taking place in Mainz (Germany). Hosted by the Energiepark Mainz, this project is testing a PEM electrolyser system with 1,2 Mw capability and with an energy storage capacity up to 6 Mw. Dr. Katharina Beumelburg from Siemens Hydrogen Solutions underlined that electricity market needs to be reformed taking into account energy storage for a reliable RES deployment.

Thyssenkrupp, the steel producer company, referred to its is work on carbon storage and use with the aim to reduce their carbon footprint. The aim of Thyssenkrupp is mixing stored carbon with hydrogen produced from electrolyses for producing synthetic methane.
