Reliable, Dispatchable Power for Digital Infrastructure.

Zotera integrates the STARS SMR-MCHE hydrogen production platform with fuel-cell power generation and hydrogen storage to provide data centers with a modular, on-site source of reliable and dispatchable electricity. The architecture can complement grid power and other energy resources while strengthening resilience, supporting peak demand, and providing a scalable pathway for lower-carbon data center power.

​

Power Where the Data Center Needs It

Rapid growth in cloud computing, AI, and other data-intensive workloads is increasing both the amount of electricity required by data centers and the importance of dependable power availability. In locations where grid capacity, reliability, or expansion timelines constrain development, on-site hydrogen production can provide an additional source of controllable power located close to the load.

​

The STARS platform produces hydrogen from methane-based feedstock using its modular Steam-Methane Reforming/Microchannel Heat Exchanger (SMR-MCHE) architecture. Following reforming and water-gas shift, Pressure Swing Adsorption (PSA) produces a high-purity hydrogen stream that can be directed to fuel-cell generation or compressed and stored for later use.

​

• On-Site Hydrogen Production: Modular STARS units produce hydrogen near the data center, reducing dependence on an external merchant hydrogen supply chain.

​

• Fuel-Cell Power Generation: Hydrogen can supply PEM or Solid Oxide Fuel Cell (SOFC) systems, converting stored chemical energy into electricity without conventional combustion.

​

• Dispatchable Energy: Hydrogen storage separates production from electricity generation, allowing stored hydrogen to be dispatched when data-center demand or operating conditions require it.

​

• Peak-Shaving & Load Management: Fuel-cell capacity can supplement other power sources during periods of high demand, reducing peak grid requirements and providing additional flexibility as IT loads change.

​

• Grid-Integrated Operation: Power can be integrated through inverters, transformers, switchgear, protection, and metering into the data center's electrical architecture, with an energy-management system coordinating generation, storage, facility demand, and grid availability.

​

• Modular Expansion: Hydrogen production, storage, and fuel-cell capacity can be expanded as data-center power requirements grow, allowing the energy platform to develop alongside the facility.

​

Resilience Through an Integrated Energy Architecture

Zotera approaches hydrogen power as part of the complete data center energy environment rather than as a standalone generator. Grid supply, STARS hydrogen production, hydrogen storage, fuel cells, UPS systems, emergency generation, power distribution, and intelligent controls can be coordinated within a unified architecture based on the availability and resilience requirements of the facility.

​

Hydrogen storage adds an important operational capability. STARS production can operate independently of moment-to-moment electrical demand, accumulating hydrogen when appropriate and supplying fuel cells when additional power is required. The installed fuel-cell capacity determines maximum electrical output, while storage determines how long that output can be sustained without depending solely on contemporaneous hydrogen production.

​

Power That Scales with Digital Infrastructure

The result is a modular, controllable, and scalable energy platform that can support new data center development, expansion of existing facilities, constrained-grid environments, and facilities seeking greater energy resilience.

By integrating hydrogen production, energy storage, fuel-cell generation, data center infrastructure, and intelligent energy management, Zotera and STARS provide a pathway for bringing power capacity closer to the digital infrastructure that depends on it.
