![]() ![]() The world's largest facility for producing hydrogen fuel is claimed to be the Fukushima Hydrogen Energy Research Field (FH2R), a 10MW class hydrogen production unit, inaugurated in March 2020, in Namie, Fukushima Prefecture. Shinzo Abe tours the FH2R facility in March 2020. While this technology is still at an early stage, floating farms of lightweight devices may potentially supply remote communities. Researchers are also developing artificial leaves which integrate light absorbers with catalysts and can produce hydrogen directly from water. Obtaining hydrogen from these processes are being jointly studied as a viable way to produce domestically at a low cost with the least impact on the environment. Pink hydrogen is also said by many people to be hydrogen obtained when electricity which results from nuclear energy fuels the process of electrolysis. Clean hydrogen is also at the centre of nuclear fusion but because of the safety risk involved many scientists often shy away from it. This method is often expensive to undertake. Production is usually classed in terms of colour labels and about three stand out in this category 'grey hydrogen' is produced from the steam reforming of methane with the release of carbon dioxide as a by-product, 'blue hydrogen' is produced through a process where CO 2 is also produced then subsequently captured via CCS, and finally ' green hydrogen' is obtained via electrolysis, when electricity from renewable sources is run through water to separate the hydrogen and oxygen without the release of emissions. However, this reaction releases fossil carbon dioxide and carbon monoxide into the atmosphere, which are greenhouse gases exogenous to the natural carbon cycle, and thus contribute to climate change. ![]() Steam–methane reforming, the current leading technology for producing hydrogen in large quantities, extracts hydrogen from methane. As of 2020, the majority of hydrogen (~95%) is produced from fossil fuels by steam reforming or partial oxidation of methane and coal gasification with only a small quantity by other routes such as biomass gasification or electrolysis of water. Hydrogen fuel can be produced from methane or by electrolysis of water. Because pure hydrogen does not occur naturally on Earth in large quantities, it usually requires a primary energy input to get produced on an industrial scale. ![]()
