![]() They enable zero-emissions mobility for the purposes of a sustainable energy transition. The gas thus assumes an important ‘buffer function’ in the intelligent electricity grid of the future.įuel-cell vehicles are characterised by short refuelling times, long ranges, and powerful acceleration. If the electrolyser is operated directly at the wind turbine, using hydrogen as a storage medium has another benefit: when the wind delivers more energy than is needed in the electricity grid at a given moment, this electricity can be temporarily stored in the hydrogen by splitting water. wind power, the hydrogen is emission-free – known as ‘green hydrogen’. If the electricity comes from renewable sources, e. This involves using an electrolyser to split water into its components hydrogen and oxygen – the energy used for this remains stored in the hydrogen. On an industrial scale, hydrogen is now mainly produced by reforming natural gas – a process that releases CO2 among other things.Īlternatively, hydrogen can be produced from water using electricity. Most of the hydrogen produced today is created as a by-product or co-product in processes of the chemical industry and is consumed again by the same industry. While pure hydrogen exists in abundance in the blazing-hot interior of the sun and in the vastness of space, on earth it is only present in bonded form. No smoke or fumes are produced unless other substances are burned. In the event that hydrogen catches fire, the rate of combustion is relatively high. ![]() Hydrogen is non-toxic and cannot contaminate soils, the atmosphere or humans. %) –an explosive mixture with oxygen (oxyhydrogen gas) forms at a concentration of 18 % and above. H2 forms an ignitable mixture with oxygen in a wide range (4 vol. ![]() Hydrogen (H2) is the lightest known element – about 14 times lighter than air. ![]() In fact, hydrogen even has safety advantages over other fuels. When it comes to safety, hydrogen is often the subject of prejudices. Today, it is used in many industrial and technical processes. Discovered in 1766 by the English chemist Henry Cavendish, it has been used as an industrial gas for over 100 years. ![]()
