Maximising energy security for Alder Hey Children's NHS Foundation Trust
The Hospital, which is run by the Alder Hey Children's NHS Foundation Trust, will open Alder Hey Children's Health Park, a new iconic purpose-built hospital, in Springfield Park in 2015.
To meet the NHS's carbon reduction target of 26% by 2020, the Hospital was looking to reduce the overall carbon footprint and energy costs while guaranteeing stable supplies of heat, electricity and hot water to the patient care environments in the new facilities at the Alder Hey Chidren's Health Park.
Veolia (Cogenco) Combined Heat and Power worked closely with the Hospital to design and install a CHP system that incorporates both renewable and mains gas fuels. The system utilizes a 500kWe gas-fuelled CHP and a 500kWe biodiesel CHP installed at the Hospital's new facilities.
The CHP units will supply the state-of-the-art Hospital with power and low-grade hot water. During cogeneration the heat produced as part of the electrical generation process is recovered by the CHP and used to heat water. This increases the efficiency of fuel utilisation, lowers utilities costs and, in line with the NHS's carbon reduction target of 26% by 2020, will help to reduce the new Hospital's carbon footprint.
The CHP plant, which utilises the heat produced in electricity generation to provide hot water, will allows the hospital to produce its own energy in an efficient and sustainable way. Fossil fuels are used only once in the process to generate heat and electricity rather than the traditional method of generating heat through boilers and electricity from the Grid.
By integrating gas and biodiesel-fired units the new energy plant will maximise energy security for the hospital, and deliver carbon savings estimated to be 2,300 tonnes of CO2 per year.
Both CHP units maximise the energy efficiency for generation of heat and electricity and the biodiesel unit also increases the CO2 savings by generating utility supplies using renewable fuel. The CHPs will deliver the energy security needed to support patient care and reduce exposure to electricity price changes.
