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

An interconnected offshore grid of North Sea wind farms with an output of 68,400 megawatts could serve up to 70 million households by 2030. Constructing such a grid, as outlined in a new commissioned by Greenpeace, would cost around €15-20 billion. “Building a North Sea grid is not just a pipe dream; it’s common sense both environmentally and financially. Greenpeace calls on the Commission to deliver a strong EU Action Plan for offshore wind and to push for a coordinated approach to make this scenario a reality,” said Greenpeace campaigner Frauke Thies in a statement. The Commission is due to present an action plan on offshore wind this autumn, as part of a wider EU Strategic Energy Review. The plan will include recommendations on how to coordinate member states’ efforts to realise such large-scale offshore wind projects, according to Commission official Hans van Steen, head of unit for renewables regulatory policy in DG TREN.
