We use the fuel cells in smart grid projects to complement photovoltaics, e.g. as part of the TH-E Box and the electric car charging infrastructure. In addition, we have been able to show that the methanol fuel cell is excellently suited for the power supply of electric boats. If the methanol is produced using CO₂ from the atmosphere and hydrogen electrolysis, then the entire cycle can be seen as a regenerative seasonal long-term storage system, making the energy transition fully feasible.
ISC Konstanz has several fuel cells, each with up to 5 kW electrical power, which obtain the required hydrogen from methanol by means of an upstream reformer. Methanol, the simplest alcohol, can be produced using renewable energies and is easy to store in liquid form at room temperature and normal pressure.
