Decarbonisation gains at Berlin power plant


Johnson Controls Industrial Refrigeration business has deployed its Sabroe heat pump technology with a 700kW heating capacity at Vattenfall Europe Wärme AG’s Berlin-Buch, combined heat and power (CHP) plant in Berlin, Germany


T


he installation will support the European energy company in its goal to eliminate carbon emissions from its heating and power


generation facilities by 2050. The CHP plant currently uses a heat recovery boiler to capture waste heat from an existing gas turbine to generate heat for the local district heating network. The addition of the heat pump will boost the plant’s district heating capacity without burning any additional fossil fuel, thus contributing to energy security and avoiding the production of about 620 tonnes/year of carbon dioxide emissions. In Berlin, Vattenfall operates the largest urban heating network in Western Europe with around 1.3 million connected residential units. A total of 2,000 kilometres of pipelines supplies the connected properties with 80 to 135°C hot water which provides heating and hot water to connected residences. The Buch island network in the north of


Berlin supplies a total of around 10,000 apartments and 500 individual facilities such as schools or clinics with climate-friendly heat. “This project puts the power of heat pumps to work to meet energy needs while cutting waste, emissions and costs. Importantly heat pumps deliver required heating without the need for additional gas supplies,” said Dave Dorney, vice president & general manager industrial refrigeration at Johnson Controls. “We are proud to be part of the energy transition here in Germany and this project gives us the opportunity to put our large heat pumps to work and provide energy, environmental and security solutions.” “The new heat pump installation at Berlin-Buch is part of our goal to enable fossil-free living in one generation, while still delivering on our customers’ expectations for the supply of affordable electricity and heat in the city of Berlin. We are proud to be part


of the pioneering effort to roll-out heat pumps across Germany’s energy sector,” says Andreas Heuer, Asset-Manager dezentrale Anlagen, Vattenfall. “Cutting carbon emissions from the use of


fossil fuels in heating/cooling, whether for district heating, industrial processes, or in buildings, has to be a top priority if we want to achieve a net-zero economy in the fight against climate change,” said Katie McGinty, vice president & chief sustainability and external relations officer at Johnson Controls. “Heat pumps are vital since they cut natural gas needs and bolster energy security even as they enable us to take on the almost 40% of global CO2 emissions that come from buildings. Natural gas is the primary source of energy for building heating, so we are eagerly ramping up our production of heat pumps and other solutions to meet the challenge of improved building efficiency and a net zero and secure energy future”. Both Vattenfall and Johnson Controls are

Southampton care home enjoys benefits of CHP


Helec, an M&E specialist in the specification, design and installation of combined heat and power systems (CHP) within pre-packaged plant room solutions, has supplied and commissioned an Energimizer EM16NG CHP unit to Barchester Healthcare’s Snowdrop Place care home in Botley, Southampton


H 22 July 2022


elec was tasked with this project in December 2019, when it worked with the main M&E contractors’ consultant Mark


Comerford to optimise the hydraulic layout. Work started in May 2020, when the CHP unit was delivered to site, but the pandemic delayed the build, so it was eventually commissioned in December 2020. Helec supplied and commissioned the CHP in the plant room on behalf ofAs this is an upper floor plant room, the CHP had to be extra quiet with its running noise. The acoustic insulation provides a sound pressure level (SPL) for this CHP at 46dB(A), measured at one metre distance – quieter than an American style double door fridge. Snowdrop Place expects


to save 104,000kWh of electricity per year, which could reduce the care home’s electricity bill by as much as £15,600 per year. Run by Barchester Healthcare, Snowdrop Place is designed specifically to support people living with dementia and those who require residential care. The care home includes facilities such as a cinema, an activities café, a salon and four spa bathrooms. Jonathan Passmore, UK technical sales manager at Helec, said: “We were delighted to support the site installation team in order to deliver this efficient 16kWe CHP unit, which will contribute well to help reduce the running costs at Snowdrop Place.”
