Steel is essential in today's economy. It's in everything from cars and buildings to medical equipment and wind turbines. But making steel from scratch is not good for the climate. At least not as it has been produced since the Industrial Revolution, in a process involving coal. The steel sector is responsible for approximately 8 % of global carbon dioxide emissions. The Global Steel Climate Council has just released a framework to change that. Some environmental groups are pushing for "green hydrogen" to replace coal in steelmaking. If ever there was a time for U.S. steel companies to invest in a green energy transition, it would be now, says Nick Messenger, an economist and senior research fellow at the Ohio River Valley Institute, a policy think tank. infrastructure projects passed by Congress and the Biden administration really put an incredible amount of money on the table" to meet the administration's climate goals, he said. Messenger recently co-authored a report on the decarbonization of steelmaking in western Pennsylvania using green hydrogen. So it's a really efficient way to still reduce iron ore to make steel,” Messenger said. The idea is that if you use renewable energy to make hydrogen and use hydrogen to make steel, the process is greener from start to finish. This so-called green steel it is quite new. (Ali Budner, MarketPlace)
