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

From October 2018 onwards Energy Stock and Gasunie New Energy started commissioning the electrolyser in project HyStock, cofinanced by the EU CEF program through the TSO2020 project. The electrolyser has an electrical capacity of 1 MW and has the purpose to convert green electricity into hydrogen. On the short term Energy Stock foresees to offer conversion capacity to support the development of hydrogen mobility. At this stage the hydrogen is stored above ground in tube trailers. The 1 MW electrolyser is a stepping stone so that in the long term, with the scale up of electrolysis, the industrial sector can be supplied and caverns can be prepared to facility large scale hydrogen storage and offer balancing services. HyStock is a first pilot towards the development of a wider hydrogen infrastructure.
