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

Toyota will launch the Mirai hydrogen fuel cell car in September, although numbers will be strictly limited. Around 100 will come to Europe a year for the first two years, with the UK taking 20-30. Pricing is likely to be £45,000 to £50,000. Partners will be carefully selected – most will be in and around London – with a view to having users who can play a vital role as a catalyst for change, said Matt Harrison, Toyota GB president and managing director.

 The Mirai, which made its European debut at the Geneva motor show in March, has a fuelling time of less than three minutes and a 300-mile range; the issue is a lack of a refuelling infrastructure. The UK will have around 15 hydrogen refuelling stations by the end of 2016 as part of an £11 million investment jointly funded by the Government and industry, rising to 65-70 by 2020. At present there are just three sites offering public access.
