As data center operators seek greener energy solutions amidst increasing power demands, many are transitioning from diesel to hydrotreated vegetable oil (HVO) for generator fuel. HVO, derived from various feedstocks, claims to lower greenhouse gas emissions. Companies like Digital Realty have implemented HVO in their operations, with success stories from trials conducted in Europe. Despite its higher initial costs, users note its long-term environmental benefits. However, analysts caution that HVO is not a fully emission-free solution, highlighting the need for realistic expectations regarding sustainable fuel alternatives.
"I pay, on average, 25 percent more than an old liter of fuel. But over the life cycle, it has a reduced impact [on carbon emissions]."
"The use of HVO as a substitute for fuel oil has allowed us to avoid emitting 2,144 tCO2 (approximately)."
