Hydrogen-fuelled combined heat and power plants make energy transition affordable

2G Energy AG from Heek is one of the leading international manufacturers of combined heat and power (CHP) plants for decentralised generation and supply of electricity and heat using CHP technology. 2G's product portfolio includes plants with an electrical output of between 20 kW and 4,500 kW for operation with natural gas, biogas and hydrogen.

The problem with renewable energies: sometimes the wind and the sun produce electricity even though it is not needed. And on other days, the demand for electricity is high, but neither the sun is shining nor the wind is blowing. This is why storage technologies are needed to bridge this time between generation and consumption. One possibility is power-to-gas technology: surplus electricity is used to produce a fuel gas such as hydrogen by means of electrolysis, which can be stored.

The combined heat and power plants often used in Germany use the principle of cogeneration: they simultaneously generate mechanical energy and usable heat. Can cogeneration plants also be operated with hydrogen produced from renewable sources? 2G Energy AG from Heek asked itself this question - and developed a solution.

Hydrogen produced and stored in a regenerative way can be converted into electricity and heat on demand in combined heat and power plants from 2G Energie. The solution developed is economical and can also be used for cogeneration plants that have already been built. In this way, seasonal fluctuations in electricity generation and consumption can be compensated for. Thanks to its flexibility, hydrogen CHP technology contributes significantly to the security of supply and the success of the energy transition. The first customer projects for hydrogen-powered CHP plants have already started.
