When applied to a proven technology such as cogeneration, it makes it possible to produce heat and electricity with zero carbon emissions."}]},{"type":"paragraph","children":[{"type":"span","value":"For businesses facing increasingly stringent regulations and the push towards CO₂-neutral solutions, hydrogen cogeneration represents a concrete pathway.

An Otto-cycle internal combustion engine produces mechanical energy and transfers it to an alternator, which generates electricity. Heat recovery takes place in two ways: from the engine cooling water, through a plate heat exchanger that makes it possible to obtain high-temperature water, and from the exhaust gases which, at temperatures close to 400°C, can be used to produce hot water, superheated water, steam or thermal oil for industrial processes."}]},{"type":"paragraph","children":[{"type":"span","value":"The key difference lies in the fuel. The plant can be powered by conventional grid gas blended with hydrogen, with the H₂ share adjustable according to availability.
