An alliance of companies in commerce, science and the political sphere has been formed in Hamburg and Schleswig-Holstein as part of the NEW 4.0 project, according to a press release in December. Participating firms including the Renewable Energy Hamburg Cluster (EEHH) will present the results of 100 projects to experts. Jan Rispens, Managing Director of EEHH, said: “The NEW 4.0 alliance features many diverse partners. Creative approaches to problem-solving are being developed and applied with expertise from diverse sectors such as the hybrid store project in Brunsbüttel or the power-to-heat station in Hamburg.”
Power from 1 million mobile phone batteries
Wind to Gas Energy in Hamburg aims to balance out the grid with a battery storage power station. Two container-size lithium ion batteries with the capacity of 1 million mobile phone batteries use power from the grid in milliseconds or feed power back into the grid. Wind to Gas is presently researching other uses and a power-to-gas station will soon generate hydrogen from wind currents, which will then be fed into the gas grid for heating or transport purposes. Tim Brandt, Managing Director of Wind to Gas, pointed out: “Net expansion lags behind at present. Power often has to be turned off, if the wind is too strong. It does not have to be turned off with power-to-gas. The surplus can be turned into alternative energy such as hydrogen.”
Power to heat in Karolinenviertel
Power-to-heat is the intelligent transfer of electric energy into heat. Vattenfall, a member of the EEHH cluster, is turning a 30-year-old electric boiler in Hamburg’s Karolinenviertel into a power-to-heat station. The company is turning excess power into district heat to stabilise the grid. “Our power-to-heat station will allow us to turn wind currents into heat in future. We are lowering the use of fossil energy and CO2 emissions and are making an important contribution to the success of the energy transition in Hamburg,” said Bernd Gross, Project Manager. The station is set to become one of the biggest power-to-heat facilities in Germany and will probably go into operation in summer 2018.
Renewable energies in era of digitalisation
NEW 4.0 is part of a programme funded by the German Ministry of Economics and Technology (BMWi). The large-scale transnational project runs until 2035 and will demonstrate how an entire region can be supplied with renewable power and the energy transition can be linked-up intelligently. The EEHH cluster and some 60 partners are working on sample solutions for safe, economic and environment-friendly energy supply.
