Hydrogen production from coal is based on gasification, with demands for coal of 57 kWh/kg H2 and for electricity of 0.7 kWh/kg H2 in the case of no CO2 capture, demands for coal of 59 kWh/kg H2 for a CO2 capture rate of 93% and demands for coal of 60 kWh/kg H2 for a CO2 capture rate of 98%.
That means the cost of CO2 could eventually add almost €0.50 to the price of a kilo of grey hydrogen in Europe, bringing the total price to around €2. In an increasingly carbon-constrained world, we should also not lose sight of the diminishing social acceptability of continuing to emit CO2 while producing and using grey hydrogen in
Grey hydrogen. Currently, the largest amount of hydrogen is grey hydrogen. The grey hydrogen represents hydrogen produced by steam reforming of
Grey hydrogen is obtained by steam reforming fossil fuels such as natural gas or coal. In this process, the waste product CO2 is released directly into the atmosphere. Ten tonnes of carbon dioxide are produced for each tonne of hydrogen extracted, so grey hydrogen is harmful to the climate.
Steam-methane reforming is a widely used method of commercial hydrogen production. Steam-methane reforming accounts for nearly all commercially produced hydrogen in the United States. Commercial hydrogen producers and petroleum refineries use steam-methane reforming to separate hydrogen atoms from carbon atoms
