It is only as big as a dishwasher, but instead of eating electricity it produces it: yesterday in Berlin, a first micro-power plant according to the Stirling principle has been put into operation. It produces heat and electricity on a natural gas basis.

Commissioning sets the starting point for a two-year field test of the Berlin gas producer GASAG. The goal of the initiative "Generating heat and electricity yourself: shaping the future - protecting the climate!" Is to install the devices in large numbers in Berlin from 2008 onwards.

The micro power plant used was developed by the New Zealand company WhisperGen. It works according to the so-called Stirling principle. This is based on a closed heat-power process, in which a gaseous working fluid is expanded by supplying heat, thereby driving a piston. High expectations are placed worldwide in this technology, as it generates electricity and heat directly at the consumer, thus largely avoiding unnecessary line losses. The technology is particularly environmentally friendly and cost-saving, as it converts the energy used into heat and electricity with great efficiency.

Climate protection contribution thanks to CO2 savings

"With this New Zealand innovation, we want to help stop global warming - many small steps - as well as our WhisperGen can help to meet this daunting challenge. I am pleased that our facilities here in Berlin can help improve the air, "said New Zealand Ambassador Alan Cook.

The widespread use of these plants is expected to result in a significant reduction in CO2 emissions. Because: Even compared to separate heat and power supply, the new systems can save around one ton of CO2 per year per household. The micropower plants developed in New Zealand and produced in Germany in the future open up prospects of decentralized and environmentally friendly power and heat production in Berlin. This would correspond to the energy policy goals of the Berlin Senate, emphasized the patron of the campaign, Berlin's Environment Senator Katrin Lompscher. display

"With the commissioning of the first plant, we want to set an example for the market introduction of this modern technology for the economical use of energy in Berlin, " said GASAG board member Andreas Prohl at the inauguration of the plant. In the GASAG field test, ten Berlin households, commercial enterprises and public institutions will benefit from a free installation of the micro power plants.
