HANNIBAL, Ohio — At an industrial site on the banks of the Ohio River, a big blue building with pipes coming in and out of it could be part of the country's transition to cleaner energy. At least its owners hope so.
Inside is a gas-fired power plant that could generate enough electricity for almost 400,000 homes. Lately, though, the company that operates the plant, Long Ridge Energy, has started blending a small amount of hydrogen — no more than 5% — in with the natural gas.
