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

European Parliament on Janaury 17, 2018 approved the recast-ed Directive on the promotion of the use of energy from renewable sources COM/2016/0767 by rapporteur José Blanco López.

For the first time even green hydrogen can be credited fully to the quota for the use of renewable fuels: hydrogen is mentioned in Article 19 regarding extensions of a guarantee of origin, which will now concern also renewable gas, including hydrogen, in the calculation of the share of energy from renewable sources in Article 7. However H2 is not double counted in GHG reduction quota as are second generation biofuels to facilitate market uptake. For hydrogen these quota should be around 2,5 or 3 to force market entry.

The Directive, among others, sets binding targets for the share of renewable energy sources in the final energy consumption of each Member State. MEPs voted for an 35% improvement in energy efficiency, a minimum 35% share of energy from renewable sources in total consumption of energy, and a 12% share of energy from renewable sources in transport, by 2030.

Results of the final vote have been +492, -88, 0 107 MEPs.

Additionally, Governance of the Energy Union file COM(2016)0759 has also been approved.  The bill includes a “carbon budget” for a first time. The final goal is to achieve zero net carbon emissions by 2050.
