he tanks look like they could hold propane, gasoline or any other form of conventional energy.
But the storage tanks in Prenzlau, some 70 miles north of Berlin, hold energy produced from wind. A hybrid power plant sponsored by four large companies is being tested there to see if the plant’s wind-hydrogen-biogas technology will work.
The system takes wind energy and turns it into hydrogen, which allows it to be stored. First electricity is produced in three wind turbines, which is then used to produce C02-free hydrogen. This so-called “green” hydrogen can be stored and mixed with biogas in a combined heat and power plant, to be used as needed in times of higher demand.
The resulting fuel can then be used for electricity or to power cars.
