With global artificial intelligence (AI) workloads on track to double data center electricity demand by 2030, sustainable alternatives to widely used diesel generators are sought. To help data center operators comply with emissions and noise standards and avoid diesel fuel supply chain issues, a compact, hydrogen-powered fuel cell system is now available from Singapore-based Horizon Fuel Cell Technologies.

The 3 MW hydrogen fuel cell module can replace diesel gensets in a footprint of just one 40 ft container and delivers 100% more power than similarly sized proton-exchange membrane (PEM) fuel cells. The small footprint is realized by use of 400 kW fuel cell stacks, which have been proven in hydrogen-powered heavy-duty vehicle applications.

Modular tanks hold up to one ton of hydrogen, delivering up to 48 hours of zero-emission backup power, depending on the load. An optional PEM electrolyzer draws from grid power during off-peak hours to split water, refill storage tanks and cut fuel costs.

In the wake of power distribution and hydrogen piping installation, the module’s smart control system handles startups, load balancing and safe shutdowns with minimal need for operator oversight.
