Tulum Energy rediscovered a forgotten hydrogen tech and used it to raise $27M
It was a mistake that was ahead of its time. Between 2002 and 2005, engineers with the Techint Group were trying to dial in a new electric arc furnace for a steelmaker when they noticed something odd. The carbon electrodes, rather than breaking down, were growing larger. The team had inadvertently created what’s known as a pyrolysis reaction, which is basically burning something in the absence of oxygen. In this case, the furnace was splitting methane into pure hydrogen and pure carbon. The te
