Nebraska Public Power District, Nebraska’s largest electric utility, plans to replace an existing coal-fired boiler at its Sheldon Station plant in Hallam, Neb., with one that uses clean-burning hydrogen fuel. The hydrogen will be produced by Monolith Materials as a co-product from its production of carbon black, which uses natural gas as a feedstock.
During its production of carbon black, Monolith Materials produces hydrogen as a byproduct. When burned, the hydrogen fuel produces no greenhouse gas emissions. Through this agreement, NPPD is expected to reduce CO2 emissions at Sheldon Station by 1.1 million tons per year. The Sheldon Station boiler using hydrogen as a fuel will be capable of generating 125 MW of electricity for NPPD’s customers. The boiler conversion is also expected to result in a reduction in other types of air emissions. It also will bring NPPD's carbon-free energy sources closer to 50 percent.
