Paul Barrett and the price of a bubble
He helped finance a hydrogen invention, then crossed the table to build the company. At Hysata, Paul Barrett is betting that a small change inside an electrolysis cell can alter the arithmetic of heavy industry.
Alex Grant
Alex Grant is the co-founder and CEO of Magrathea, an Oakland-based startup building a new electrolytic process to make magnesium metal from seawater and brine with near-zero carbon emissions. A chemical engineer who previously founded lithium-extraction company Lilac Solutions and modeled battery supply chains at Minviro, Grant started Magrathea in 2022 to reshore US magnesium production. What began as a climate play turned into a national-security one: after Russia's invasion of Ukraine tightened global magnesium supply, Magrathea won a Defense Production Act partnership with the US Department of Defense. He was a Forbes 30 Under 30 honoree in Energy in 2021.
