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

The European Technology and Innovation Platform Smart Networks for Energy Transition (ETIP SNET),  has published a Roadmap 2017-26 on a system view of the whole energy transition, addressing a scope larger than electricity grids: it encompasses interactions with the gas and heat networks and focuses on the integration of all flexibility solutions into the power system, including energy storage technologies.

The full implementation of all R&I activities is estimated at 2.5 billion euros needed to finance innovation over the next decade both for transmission and distribution systems, and to be co-financed in clusters and functional objectives. The clusters give an indication of the prioritized topics: modernisation of the network; integration of smart customers and buildings; security and system stability; power system flexibility from generation, storage, demand and network; integration of decentralized resources of these kinds; economic efficiency and digitalization of the power system; network operations; and planning and asset management. The EHA is member of the Governing board of the ETIP SNET.
