AI Data Center Energy Demand Spurs Battery, Water‑Cooling and Fusion Investments
AI compute growth is driving a rapid surge in data‑center power needs. A May 2024 Goldman Sachs outlook expects a 160 % spike in data‑center electricity use, while the International Energy Agency notes that data centres consumed about 460 TWh in 2022 – roughly 2 % of global generation – and that demand could double by 2026. AI workloads now account for 10‑15 % of data‑center electricity and are projected to use 31 % of total power by 2026.
Traditional lead‑acid and lithium‑ion UPS batteries were not built for the high‑frequency, high‑power cycling of AI clusters. Silicon‑anode batteries, which can store up to ten times more lithium ions than graphite, are being promoted as a way to increase energy density and reduce over‑provisioning of backup capacity.
Water‑intensive cooling is also under scrutiny. Ecolab has spent $7 billion, including a $4.75 billion acquisition of CoolIT Systems, to deploy direct‑to‑chip liquid‑cooling technology that aims to make AI data centres water‑neutral.
Investors are backing broader infrastructure solutions. Commonwealth Fusion Systems raised an additional $1 billion (total $4 billion) to develop fusion‑based power plants for AI data centres, while research highlights an AI‑energy‑storage nexus that could cut peak grid imports and improve renewable‑energy matching. Across the Asia‑Pacific, firms are also emphasizing overall IT‑energy efficiency, noting that traditional enterprise workloads still dominate power use.
These trends reflect a convergence of massive capital commitments, new battery chemistries, advanced cooling, and emerging clean‑energy sources as the industry seeks to sustain AI growth without overwhelming power grids.
