Project Prometheus is one of the initiatives employed by the British Army to support the UK Government in reaching net-zero carbon emissions by the year 2050. Specifically, it aims to provide more renewable energy to the UK defence sector by creating solar farms around the UK, under an allocated budget of £200 million. Initially, four pilot sites are being built, across which an estimated £1 million in efficiency costs and 2000tCO2e (tonnes of carbon dioxide equivalent) will be saved annually. The savings from this project will be reinvested into the British Army.
Changes Announced as Part of 2021 Budget
The first of these (actually the first solar farm ever built by the UK defence sector) was completed in September this year by Centrica Business Solutions. The site is located at the Army’s Defence School of Transport (DST) in Leconfield, Yorkshire. The 2.3MW solar farm comprises over 4000 solar panels and covers approximately four hectares, which is around the size of eight football pitches. Most of the energy generated will be used onsite at DST, and any surplus will be exported to the grid. This solar farm is estimated to save 700 tCO2e and reduce DST’s electricity bills by a third every year.
The other three pilot sites are already being built, and all three are due to open by Summer 2021. According to Major General David Southall, the Director of Army Basing and Infrastructure, this is just the beginning as the British Army plan to build 80 solar farms within the next decade. Project Prometheus is only one of multiple ‘green’ projects being undertaken by the UK defence sector to create a more sustainable and environmentally friendly British Army in the future. Some other notable initiatives include:
- Project Taurus: This involves building solar carports at UK defence sites across the UK, the first of which will be constructed at British Army Headquarters with electric car charging ports and battery storage.
- Project Romulus: This involves developing an information system that will detail all buildings and facilities’ carbon footprint. This system will collect and collate data on how the British Army infrastructure operates, which will be then used to drive real-world decisions.
