“We must investigate this for every single pipe we put hydrogen into,” said Jack Brouwer, director of the advanced power and energy program at the University of California, Irvine, “but it’s a phenomenon we can manage because it’s slow.” Problem pipes and compressors could be replaced over the course of years, he said. Or pipes could be protected with coatings applied from the inside by robotic devices called pigs that are currently used for pipeline inspection and maintenance. “Just put some spray-painting equipment on that same device, and there you go, right down the whole pipeline,” he said.
