The UK grid queue for contracted demand tripled to 125GW in under a year, and data centers account for 73GW of it. In places like West London and Slough, lead times exceed ten years. This article from BeBeez looks at one workaround: sleeving biomethane from new farms through the gas grid, then using fuel cells to power a 50MW data center. A 151GWh biomethane supply becomes about 90GWh of power at 60 percent efficiency, enough to cover around 20 percent of demand and open the first phase years earlier. The environmental case hinges on additionality and carbon capture. If the biomethane plant is built because a data center signs a long term offtake, it adds new renewable supply rather than relabeling existing gas. With CCS on the digester, the article argues the plant can remove roughly 17,400 tonnes of CO2 per year, matching the expected emissions of the remaining grid power under the UK's 2030 Clean Power target. That leaves operational emissions near zero. It is not a universal fix. Wind and solar still need grid connections, and fossil gas backup brings emissions and reputational risk. Biomethane is dispatchable and can connect to the gas network in about two years, which makes it one of the few options that helps data centers open sooner without relying on fossil fuel.
