New Fröttmaning wind turbine of Stadtwerke München will be illuminated with environmentally friendly energy until it is connected to the power grid.

Now it stands, right next to the Allianz Arena: Munich’s second wind turbine. In good visibility conditions it is an eye-catcher even from a distance. Nevertheless, it must be illuminated around the clock for safety reasons – even and especially as long as it is not yet connected to the public power supply. The solution for this is provided by the Munich-based company SIQENS: a highly efficient fuel cell that ensures the energy supply for the so-called obstruction fire almost silently and with low emissions.

Fuel cell research in Munich

SIQENS has been working on regenerative energy solutions based on fuel cells since 2012. This is a market that was previously covered by conventional diesel generators. Whether in emergency vehicles, on construction sites or in office containers: today, fuel cells are a highly efficient and ecological alternative. Low fuel consumption, an immense reduction inCO2 emissions and whisper-quiet operation are strong arguments not only for the operators, but also for the environment and local residents. The Munich-based company is therefore convinced that the fuel cell is an essential component of sustainable energy supply.

“We are not the competition to battery and photovoltaics, but see ourselves as the ideal complement. The fuel cell makes it possible to supply energy in places where you still had to resort to conventional combustion engines,” explains Volker Harbusch, CEO and co-founder. “Our technology is currently being used on motorways, in measuring and radio stations, but also in the construction phase of wind farms. Fuel cells offer a low-maintenance and environmentally friendly alternative for the emergency power supply of critical infrastructure. We are convinced that fuel cells will play an increasingly important role in the automotive sector, for example in battery-powered commercial vehicles.

To the Fröttmaning wind turbine

With the 2nd wind turbine in the north of Munich, Stadtwerke München (SWM) will supply green electricity for 2,800 households in the state capital from 2021. This makes the turbine four times more productive than the smaller SWM wind turbine, which has already been in place for 21 years at Fröttmaninger Berg. The company Enertools is responsible for the energy supply on the construction site and uses SIQENS fuel cell technology to operate the so-called obstacle fire.

About SIQENS

SIQENS, founded in Munich in 2012, develops and produces methanol fuel cells. The units are used as an alternative to diesel generators and are used for emergency power supply, as well as in places without a fixed connection to the power grid.

The SIQENS fuel cell system, the Ecoport, is operated with liquid methanol. Hydrogen is produced from the methanol in the Ecoport. This reacts with oxygen to generate electrical energy. The Ecoport is connected to a battery and automatically recharges it when needed. Connected electrical devices are supplied directly from the battery. Thanks to patented circuits for the recovery of process media and energy, the system runs particularly efficiently.

In contrast to diesel generators, fuel cells are economical, require hardly any maintenance and emit neither fine dust nor nitrogen oxides, as well as significantly reducedCO2 emissions. If methanol from regenerative sources is used, operation is completely climate-neutral.
