Accumulated Carbon Emissions
from using groundwater heat pumps at BEN (in blue) vs using gas boilers (in orange)

The graph shows the accumulated carbon emissions from the BEN project over the next 20 years in blue. The level of carbon emissions if the project had been continued to be heated by gas boilers is shown in orange. The orange lines increase by the same amount each year. The carbon emissions from using heat pumps decreases each year as the grid is decarbonised.
The graph uses projected decarbonisation rates for grid carbon intensity published by DEFRA.

The projected carbon emissions savings of using the heat sharing Network at LSBU amount to 7,287 tonnes of CO_2e over twenty years.
