The next generation of AI compute will run on 800V DC and demands unprecedented power density. Yet todays infrastructure delivers AC, forcing costly conversion stages that consume capital, waste power, and require equipment and space that are in short supply Bloom fuel cells generate continuous 800V DC power natively and reduce capital costs, space and power needs, and also eliminate delays created by power equipment shortages For a 1 GW AI data center, Blooms 800V DC solution translates to a reduction of non-compute CAPEX by $3.6 billion, or 27%, and five-year total cost of ownership by...
