By comparison, 69% of steel today is made at approximately 1,600 degrees Celsius (2,912 degrees Fahrenheit) using coal, emitting about two tons of carbon dioxide for every ton of steel produced. Conversion of iron ore into iron accounts for 90% of steelmaking emissions that may be eliminated using Electra’s process.

The basic concept of power-to-gas (or e-Gas, as Audi calls it), is to “store” excess renewable electricity by producing hydrogen, which can then either be converted to methane; injected into the gas distribution grid directly; or used as a vehicle fuel. The municipal gas distribution networks can manage these quantities in principle.
