Hydrogen – the most abundant element in our universe – can be used as a fuel, but is also used by the chemical industry. It is mostly produced from natural gas (which yields H2 and CO2).
Production through electrolysis of water is also possible, but this is more expensive. However, this process is promising for ‘power to chemicals’: using surplus energy from wind or solar to produce hydrogen by electrolysis.
In February 2018, a hydrogen filling station was opened in Delfzijl, servicing regional busses with green hydrogen from the Nouryon Specialty Chemicals chlorine plant. At the Delfzijl chemistry park, Evonik Peroxide produces bleach (H2O2) from hydrogen. Any excess hydrogen produce by the chlorine plant is used for heating, through the Nouryon Delesto cogeneration power plant.
Hydrogen is produced by different plants in Delfzijl. It is a ‘waste’ product from the chlorine plant of Nouryonin Delfzijl. Also Evonik produces hydrogen for its hydrogen peroxide plant. Several projects are in development for large scale production of hydrogen by Power2Gas, as part of the development towards a hydrogen economy.
