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

An innovative off-grid housing development in Chiang Mai, solar powered hydrogen storage multi-house complex. Thailand-based development company CNX Construction built the world’s first 24-hour, The houses are powered entirely by a solar-hydrogen system — a world’s first for energy storage of its size. The solar-powered hydrogen storage system provides 24-hour, year-round access to clean energy, even during periods of bad weather. The company has not released cost figures for the project, but said, “We have calculated a return on our investment (ROI) based on 5 to 6 Thai Baht/kilowatt hour. The time for a ROI will be around 15 years as of today.”
“Due to its widening acceptance, the cost of similar systems will drop within the next 3 to 5 years and will generate a much faster ROI,” the release added.
