Cranfield University in Bedfordshire has a combined floor area of more than 66,000m2 and a high annual heat demand of between 6 and 7,000,000kWh. The campus needed a high performance, reliable supporting system – one that would not only fit seamlessly within the existing district heating setup, but would also provide a cost-effective and sustainable fuel solution for the campus’s future.
The university is now benefiting from a future-proof energy supply thanks to the installation of a 960kW Flogas Renewables biomass system. Integrated into the existing 1.4MW gas-fired CHP system – together they now provide 24/7 heating and hot water for 34 campus buildings. The boiler is interconnected to a new steel-framed fuel store, which holds the system’s wood chip supply. This top loader store has a capacity of 135m3 and can comfortably take a full lorry’s worth of woodchip (27 tonnes).
The biomass boiler is expected to provide more than 30% of the university’s entire annual heating demand each year (with outputs of between 2 to 3,000,000 kWh) and is set to save up to 500 tonnes of CO2 – reducing its carbon footprint by around 5%. The university has also applied for the Renewable Heat Incentive (RHI), which means it will benefit from guaranteed, index-linked payments for all the renewable heat it generates over the next 20 years.
"We specifically opted for a biomass system, because it’s sustainable, effective and will ultimately help us protect against future market volatility. Flogas Renewables was able to provide us with a solution that met our exact needs and they continue to work with us to ensure we achieve the very best outputs, savings and returns from the system."
