Stack Infrastructure, a datacenter operator based in Denver, Colorado, has introduced hydrotreated vegetable oil (HVO) as a biofuel for backup power at its Oslo, Norway facility. This move aims to offset greenhouse gas emissions and align with the company's sustainability goals. HVO100, being 100% vegetable oil, offers a cleaner alternative to diesel, significantly reducing carbon dioxide emissions and other pollutants. Stack Infrastructure is dedicated to eliminating Scope 1 emissions from its datacenters, with HVO biofuel playing a key role. The company emphasizes the importance of sustainability in designing and operating critical infrastructure. Similarly, Digital Realty and AWS have initiated transitions to HVO in the US and Europe, following successful trials. HVO's benefits include stability in cold temperatures and comparable performance to traditional diesel, without modification to generators. Additionally, Equinix explores fuel cell technology, while NorthC in the Netherlands has already implemented hydrogen fuel cells. This industry shift towards biofuels and alternative power sources reflects a collective effort to create greener and more sustainable datacenter operations.
