Bloom Energy has introduced an 800 V DC-native fuel-cell power architecture designed to provide continuous direct-current power for AI data centres.
The company’s solid-oxide fuel cells generate 800 VDC directly rather than producing AC power that must subsequently be converted for computing equipment. Bloom says this could eliminate several conversion stages, including some transformers and switchgear, reducing energy losses and infrastructure requirements.
According to Bloom’s modelling, the architecture could reduce non-compute capital expenditure for a 1 GW data centre by $3.6 B, or 27 %, and lower five-year total cost of ownership by $5.5 B, or 9 %, compared with conventional AC-based infrastructure.
Bloom stressed that these figures are projections rather than demonstrated savings. Actual results would depend on factors including site design, energy prices, equipment costs and deployment decisions.
The company pointed to Nvidia’s planned adoption of 800 VDC architecture for future systems as an indication of changing data-centre power requirements. Bloom’s 2026 Mid-Year Data Center Power Report also found that industry respondents expect DC-based architectures to account for 58 % of new deployments by 2030.
The development comes as data-centre operators seek power architectures capable of supporting increasingly power-dense AI computing infrastructure.
