The total water use of hydrogen “is not the big deal,” said Jack Brouwer, an engineering professor at University of California-Irvine. “The water challenge is that where we have good primary energy from wind and solar, we do not have good water (supply) necessarily.”... Companies and governments in arid places like California will eventually need to invest more in power lines or water pipelines to connect sunny areas to water resources for green hydrogen production, said UC-Irvine’s Brouwer, who is also part of the ARCHES leadership team.  “We run a wire from the good solar to where the water is,” he said. Read More
