ARK DATA CENTRES
historically leveraged diesel generators are in the process of being transitioned to bio-diesel. For every new London facility Ark is committed to eliminating diesel by deploying back-up gas generators proven to run effectively on up to 30% hydrogen. “We support the UK’s ambition to incrementally increase the hydrogen mix in its utility gas network and we are pushing hard for the tests to be completed which will allow 100% usage,” adds Owen. “Our campuses are ecologically level and feature green areas where wildlife can 76

coexist. We have eco-toilets on our sites that save thousands of litres of water each year. We’ve also extended our typical rainwater harvesting process to capture water from the roof but also from the run-off of the car parks which can then be filtered and stored. It may involve a more intense filtration process but by re-using this water, we only use the mains to top up the rainwater supply as required, significantly reducing our usage.” Water consumption is a key example where a data centre could either potentially
