The Securing Healthy Returns report released in the UK has reveald combined heat and power (CHP) allows £26.4m of energy savings every year.
Published by the Sustainable Development Unit (SDU) for NHS England and Public Health England, the report analyses the financial value of major sustainability measures in the National Health Service (NHS) England. It has evaluated 35 proven measures, which could achieve a total cost savings of £400m and reduce carbon emissions by one million tonnes each year by 2020.
CHP facilitates cost and carbon savings by efficiently capturing heat wasted in conventional power generation and using it on-site for both heating and cooling.
The Heart of England NHS Foundation Trust has partnered with UK-based environmental consultant ENER-G to introduce the CHP technology to its Birmingham Heartlands Hospital and Solihull Hospital.
ENER-G Cogen International technical director Chris Marsland said: “Due to the 24/7 heat demand of acute hospitals, CHP can operate at efficiencies in excess of 85%, more than double that of other coal and gas-fired generation sources the Department of Energy and Climate Change's half-hourly modelling shows it displaces.
“As such, the cost and carbon savings really stack up and more hospitals should specify CHP to provide assured cost and carbon savings long into the next decade and beyond.”
Of the 18 energy saving measures covered in the current report, CHP facilitates the highest potential cost savings (£26.4m) every year. According to the SDU, CHP also has the ability to reduce carbon emissions by 3,750t each year.
