Within two years Delfzijl will have the world’s first large-scale Power-to-Gas plant. The plan is to build a 12-Megawatt plant that produces hydrogen and syngas for the chemical industry. Torrgas, Siemens, Stedin, Gasunie, A.Hak, Hanze University of Applied Sciences / EnTranCe and the Energy Valley foundation signed a declaration of intent for the construction of the plant at the Hannover Messe on 10 April.
Syngas represents a substantial step in improving the sustainability of the chemical industry. The power-to-gas technology also presents a solution for the storage of temporary surpluses of wind and solar power.
The plant will convert green electricity into hydrogen and oxygen via electrolysis. The hydrogen can be used as a raw material for the chemical industry. Combining it with CO2 produces methane (natural gas). This gas can then be added to the natural gas network or used as a clean fuel. The oxygen produced is used at the gasification plant of Torrgas, where biomass is gasified into syngas, which in turn becomes another useful raw material for the chemical industry.
Converting into hydrogen and green gas makes it possible to store green current in the gas network, after which it goes to households, transport and gas-fired power plants, for example. Power-to-Gas could thus eventually present a solution for the storage of electricity produced by wind turbines and solar panels that cannot be used by consumers as soon as it is produced.
The plant being built in Delfzijl is not only the first in the Netherlands, but also the biggest of its kind. There are already many power-to-gas initiatives in Germany, but on a much smaller scale.
