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

London Metropolitan Police will have the world’s largest fleet of hydrogen fuel cell electric police vehicles as the first fleet of 11 Toyota Mirai police cars has been delivered on March 16, 2018 The Mirai fuel cell cars have been co-funded by the European Union’s joint programme with FCHJU (Fuel Cells and Hydrogen 2 Joint Undertaking) and will be used across the city. According to Toyota, the Mirai police cars will cost around half the price a conventional diesel squad car to run, and can theoretically cover more than 300 miles on a single tank.
Met Commander Neil Jerome said that the Toyota Mirai’s  “Are our first entirely zero emission response vehicles and this is an exciting development for us. The Met is committed, alongside the Mayor, to making the service as environmentally friendly as possible and a big part of that work is ensuring our fleet is green. Since late 2015 we have been actively looking at ways to hybridise and electrify our fleet as well as exploring other new technologies such as hydrogen.”
