CHP ROUND-UP ‘Low-carbon’ energy centre opens


York Teaching Hospital NHS Foundation Trust chose last month’s NHS Sustainability Day 2017 to open its new low-carbon energy centre at Scarborough Hospital.


Delivered in partnership with Vital Energi, it will deliver over £9.1 m in guaranteed financial savings and almost 32,000 tonnes of carbon reduction over a 15-year Energy Performance Contract. The upgrade at Scarborough includes improved boiler control and the installation of a CHP unit which Vital Energi says will significantly contribute both to reducing carbon emissions, and the hospital’s energy costs. Carbon emissions are projected to be cut by 2,130 tonnes, or 38%, annually. The unit will supply all the hospital’s night-time electricity, over 70% of its daytime electricity, and contribute substantially to the heating and hot water supply. The energy centre was officially opened by Trust CEO, Patrick Crowley, joined by Brian Golding, director of Estates and Facilities, members of the hospital’s Estates


Potential to cut sector’s energy expenditure ‘by millions’


Even with the Government cash injection announced in the spring Budget, pressure is mounting within the healthcare sector to make cost savings across the board.


team, and representatives from Vital Energi, including joint MD, Ian Whitelock. Brian Golding said: “In 2014 we completed a major energy-saving and carbon reduction project at York Hospital using a Carbon and Energy Fund Framework with Vital Energi, and last year completed a major carbon reduction project at Bridlington Hospital. Including the work here, the overall project will offer the Trust over £26.5 m in guaranteed savings, and a 27.6 per cent reduction in annual carbon emissions.”


Stoke Hospital ‘delivers on green ambition’


The Royal Stoke University Hospital, part of University Hospitals of North Midlands NHS Trust, has installed a high efficiency ENER-G CHP system to improve its environmental performance and reduce energy costs.


ENER-G successfully tendered to replace the hospital’s existing Deutuz 1280 kW CHP with a new, highly efficient ENER- G 1.2 MW unit. After decommissioning and disassembling the existing unit and reorganising the plant room, ENER-G installed the new cogeneration system, which benefited from NHS Energy Efficiency Capital Funding. ENER-G is supplying a full CHP operation and maintenance package,


including 24-hour remote monitoring, and all-inclusive parts and labour required to rectify faults or repairs for the contract term.


Charlie Cox, energy manager for the University Hospitals of North Midlands NHS Trust, said:


“Being able to generate our own power locally on site means there is a lot less energy wasted through transmission and distribution.”


The ENER-G CHP engine is reducing the general hospital’s CO2


emissions by


approximately 2,792 tonnes per year – almost 8% of the Trust’s carbon footprint. The Trust’s annual energy costs are also expected to be reduced by over £400,000 within five years.

networks, for which the Government has announced support via a £320 m investment in the next five years. Hamworthy Heating said: “CIBSE guidance AM12 – Combined Heat and Power for Buildings (CHP), makes specific reference to a minimum 30˚C differential temperature for heat network design – to keep flow rates and pipe sizes small, and maintain a lower return temperature even when demand is low, for more efficient plant operation.

With – Carbon Trust data reveals – £400 m spent annually on energy, heating technology specialist, Remeha, says innovative heating technologies like CHP could offer a solution. Technical sales director, Gary Stoddart, said: “A recent report from the Sustainable Development Unit (SDU) for NHS England and Public Health England shows that switching to CHP is likely to save the NHS £26.4 million a year. CHP systems burn natural gas to generate heat, while providing electricity to supplement or replace the grid supply. By generating electricity on site, energy bills can be reduced by around 20% compared with conventional power generation.” Cockermouth Community Hospital and Health Centre in Cumbria specified CHP as part of an energy and carbon-saving strategy to meet long-term environmental goals and BREEAM targets. An R-Gen SenerTec Dachs 5.5 kWe unit was installed to provide hot water for general medical needs and electricity to supplement the main grid supply and power the plant room.


Gary Stoddart said: “On visiting the site, a Remeha engineer identified an opportunity to vastly improve system efficiency by ‘tweaking’ the boiler temperatures down by 1-2 degrees C. We could thus get the CHP running almost continuously, meaning that the hospital is benefitting from significant carbon and energy savings.”


of up to 40 °C differential temperature and a maximum flow temperature of 90 °C, Hamworthy Heating’s Wessex ModuMax commercial boiler range is ideally suited to support renewable energy products as a secondary heat source, including CHP, in a heat network.” The Wessex ModuMax mk3 gas condensing boiler provides high outputs on a small footprint. Modules can be combined flexibly, and stacked vertically. Close load matching ‘allows more efficient operation and less wastage of energy’.
