SUSTAINABILITY have no direct CO2 emissions. Likewise, heat
pumps for district heating and industrial processes can deliver three times more heat energy than the electrical energy they consume and when used to simultaneously deliver cooling, they can reach an efficiency of 7; for 1 unit of electricity, 4 units of heat and 3 units of cooling are generated. Furthermore, if powered by renewable electricity, both refrigeration systems and heat pumps offer low cost, zero carbon heating and cooling”. “But even with COP26 just around the corner, our government’s policies are still favouring fossil fuel production. We’ve just heard that the UK government is one of 15 major economies planning to continue to extract fossil fuels up to 2030. In total, the United Nations report says, they will produce around 110% more fossil fuels than would be consistent with limiting the degree of warming to 1.5. And this is totally incompatible with Paris Agreement goals.” It is clear that we can no longer rely on fossil fuels such as gas and coal, but the demand for heating is still there. Scotland has been at the heart of a district heat pump revolution, with the Queens Quay development investing in two water source heat pumps on the Clyde Estuary.
Just five miles away from where COP26 talks will take place, Star’s two 2.65-megawatt (MW) water source heat pumps convert heat held within the water of the River Clyde into hot water at a temperature of 75 degrees centigrade and distribute it to 1,200 homes and businesses. When fully operational, the £20 million district heating network, built for West Dunbartonshire Council (WDC) and delivered by Vital Energi, will save 2000
tonnes of carbon reduction from being emitted to the environment per year. Star’s low carbon heat pumps have won numerous awards most recently the EHPA’s European Heat Pump City of the Year Award awarded to Clydebank in September 2021. Star has also been recognised for its years of
leading in energy efficient cooling technology and natural refrigerants by achieving the Net Zero Achievement Award from the Glasgow Chamber of Commerce’s Glasgow Business Awards. Star’s pioneering industrial refrigeration systems use natural refrigerants, such as carbon dioxide (CO2
) and ammonia
(NH3), to deliver operational efficiency with low carbon emissions and were commended by the judges.
Mr Pearson added, “The potential for low
carbon heating and cooling using heat pumps is colossal – but it requires joined-up thinking, economic support and policies to encourage local authorities and industry to invest. Time is running out on fossil fuels and the barriers to eliminate them maybe high but they are paper thin and policy based that could be changed overnight.”
