"very high temperature transforms hydrogen into plasma, which is a significantly more reactive form... plasma is much more effective at removing oxygen from ore, producing desired metal... same carbon from coal process, but instead of CO₂, only water vapor produced... examining how the technology can be scaled up, and the energy resources and set-up required"
