The project will use solid waste byproducts — such as petroleum coke combined with biomass — to produce hydrogen. : Battery-electric and hydrogen-powered truck maker Nikola Corp. said Wednesday it plans to invest $50 million in cash and stock in a hydrogen energy project in the Midwest. The project involves a gasification plant in West Terre Haute, Ind., acquired in 2016 by Wabash Valley Resources, which intends to convert it into a hydrogen production plant and carbon capture project. In exchange for its investment, Nikola will take a 20 percent equity interest.
