COMPRESSED AIR, VACUUM AND GENERATORS 32 HYDRAULICS & PNEUMATICS July/August 2023 www.hpmag.co.uk In April last year, the British Compressed Air Society (BCAS) launched the 10% Taskforce - a call for UK businesses to take simple steps to cut their compressed air energy usage figure by 10%. The campaign has an ambitious target to save over 411 thousand tonnes of CO2, the equivalent of taking 317 thousand cars off the road. When BCAS launched the campaign, no one could have predicted the scale of the rise in wholesale gas and electricity prices. The campaign’s original calculations of £485.43 million being spent in wasted electricity have now risen two or even three-fold. Generating compressed air can be very energy intensive, representing as much as 30% of a site’s total electricity bill. According to a report entitled ‘Compressed Air Systems in the European Union’1, when looking at the most Compressed air systems: The importance of ensuring energy performance is optimised Cliff Warne, BCAS Executive Director explores the importance of compressed air system design to ensure energy performance is optimised, highlighting the various options available to calculate the annual running cost of an air compressor, while also advising on how best to design an energy-saving system. important energy savings techniques available to compressed air users, ‘the energy savings amount to 32.9 per cent, achievable over a 15-year period.’ Therefore, since the launch, BCAS members have been speaking with customers to encourage them to act and realise savings now.
