Cutting edge science park turns to CHP and thermal storage

16 September 2010 – RWE Innogy subsidiary company BTB GmbH has inaugurated a new energy centre comprising four CHP units to supply the prestigious Adlershof Science Park, in Berlin, with heat and electricity.
à‚ 
The heat supply has been designed to be especially efficient through operation of five pressurized heat storage units.
à‚ 
The Adlershof CHP plant has a total capacity of 8 MW of electricity and 8 MW of thermal energy.
à‚ 
The key technical feature is that surplus heat created during the power production is stored for the interim in five hot water pressure stores and can then be called up when needed and fed into the district heating network.
à‚ 
With CHP, heat has to be produced at the same time as the electricity, in this case mainly during the midday hours with maximum electricity generation. However, the main demand for heat at the site is in the early morning and evening hours. The technique of interim storage of thermal energy, being used in Berlin for the first time, permits a highly efficient alignment with that demand structure, says RWE.
à‚ 
‘We are proud of being able to develop an innovative and demand-driven solution for the Adlershof Science Park,’ said Prof Dr Fritz Vahrenholt, CEO of RWE Innogy.
à‚ 
‘With the new energy centre we are reducing carbon dioxide emissions by more than 18,000 tonnes per year. RWE is thus making a key contribution to achieving the federal capital’s ambitious climate protection targets.’
