Decentralized hydrogen production in the immediate vicinity of the energy producer, e.g. wind, water or sun, and the consumer has many advantages. Surplus energy can be stored in the form of hydrogen and converted back into electricity via fuel cells. The resulting waste heat is used via heat exchangers and fed into a local heating network. Self-sufficient power and heat supply with simultaneous relief of the grid supply. Ecoclean supports neighborhoods in implementing sustainable power generation and heat supply concepts.

Hydrogen plays a particularly important role in the climate-neutral supply of entire urban and residential districts. Green electricity is produced with the help of a photovoltaic system on the roofs of the residential or commercial buildings to be supplied. This supplies the electrolyzer. Here, the surplus electricity is converted into hydrogen and stored. At times when the electricity from the photovoltaic system is not sufficient to supply the residents, the stored hydrogen is converted back into electricity with the help of a fuel cell. The waste heat generated in the electrolyzer and the fuel cell can be used to heat the neighborhood via a local heating network.
