How steelmaking may go carbonfree—by dropping its addiction to coal
This approach doesn't use coke as a raw material. But it does require significant amounts of electricity to heat metal to nearly 3,000 degrees Fahrenheit—and most of that power comes from coalfired power plants. At Boston Metal's research facility, the steelmaking process takes place inside a squat metal cylinder called an electrolytic cell.
