Hydrogen plays an important role in the substitution of fossil fuels. It is generated through the electrolysis of water, which is broken down into oxygen and hydrogen. If electricity from renewable sources is used for this process, the resulting gas is known as green hydrogen, as no CO2 is generated during its production.
CO2 emissions can be lowered significantly by using green hydrogen – thereby making an important contribution to climate protection. Many experts view green hydrogen as an energy source for the future in the areas of industry, heat supply and mobility.
Examples of industrial use
Industrial consumers of green hydrogen include the steel and chemical industries. Among other things, the chemical industry uses green hydrogen to replace mineral oil as a raw material. Green hydrogen can heat industrial furnaces – such as those in the glass, cement and steel industry.
For supplying heat
Hydrogen can already be fed into the existing gas grid today in certain quantities. The current limit is 10 per cent, but higher proportions are also technically feasible. The additional hydrogen, preferably green hydrogen, can then be burned in the same manner as natural gas, with only water vapour being produced during combustion. Furthermore, fuel cells can produce heat and electricity using hydrogen.
Wherever electric motors are not feasible in the foreseeable future, green hydrogen can be an important alternative to fossil fuels. This is the case in aviation, shipping, heavy goods transport and transport over long distances.
High water quality required
EnviroChemie is the right partner when reliably high water quality is required for the production of green hydrogen with electrolysers. Depending on the quality of the water to be treated, e.g. whether it is fresh water, well water or non-potable water for industrial use, our experts plan suitable water treatment plants for the electrolysers. These include water treatment plants for producing pure water for the electrolysis process, as well as polishing plants for recycling the water in the electrolyser where required.
