Mitsubishi Heavy to build biggest zero-carbon steel plant
South Australia has started producing "green" hydrogen and will be shipping it compressed to the city of Whyalla. I only mention that because one of the trouble's with hydrogen is transportation, so they must have found at least some solutions, might be worth checking out for anyone interested.<p>In this same city, the steel plant will exceed it's emissions limits for this year, and so the hope is to see a hydrogen process start taking replacing the current coal process soon.<p>The hydrogen plant is also supplying a mix of hydrogen and natural gas to the local gas supply, which is pretty rad too. Yet another way hydrogen can help cut reliance on fossil fuels. I don't know what the blend's carbon output is when burned, but reducing the demand for fossil fuels is a net positive in detering investment into drilling and mining. Having a renewable source for a general combustion gas is excellent.
