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

At an informal meeting on September 2-3 among 46 nations in Geneva, Environment ministers and senior officials examined how to raise a promised $100 billion a year for the Green Climate Fund  from 2020. Revenues from carbon markets, higher plane fares or taxes on shipping – could be managed by the Fund.  Mexico’s Foreign Minister Patricia Espinosa said a Green Fund would only be agreed as part of a broad package in Cancún, including ways to share clean-energy technologies or protect carbon-absorbing forests. She said all elements of the package had to be agreed, or none. US climate envoy Todd Stern told a news conference that the meeting had been “pretty constructive”. Mexico will host an annual UN climate meeting in Cancún from 29 November to 10 December. A Green Fund is meant to help poor nations shift from fossil fuels and cope with projected floods, droughts, mudslides and rising seas caused by climate change. It will include funds for technology cooperation between developed nations and emerging economies. The EHA has been approached by South Africa and a West Africa Hydrogen Network to look for potential hydrogen cooperation.
