GeoPrime Energy · Deep DiveDevelopment Roadmap
A staged, milestone-driven program taking the HG-250 from architecture definition through field demonstration, in parallel with commercial execution across the 600+ MW pipeline.
HG-250 Development Sequence
Conceptual Design
Architecture definition, stack qualification, and system modeling.
Detailed Engineering
Subsystem design, thermal management, and controls development.
Prototype Build
System integration, bench testing, and initial validation.
Field Demonstration
Deployment of the 250 kW unit at a strategic partner site; 5,000-hour initial validation target.
Engineering Workstreams
| Workstream | Scope of Work |
|---|---|
| Stack Cartridge | Mechanical, thermal, and electrical interface design for qualified third-party stacks. |
| Hot-Box / BoP | High-temperature enclosure, insulation, and balance-of-plant integration. |
| Controls / Software | Embedded and supervisory controls, plant orchestration logic, and the owned intelligence layer. |
| Power Electronics | Inverter selection, DC/AC conversion, and grid-interface design. |
| Packaging / CHP | Containerization, heat recovery system, and site integration design. |
Near-Term Execution: 30 / 60 / 90 Days
Alignment & Definition
Confirm Gen 1 architecture, down-select stack suppliers, establish core design targets, and define the initial demonstration site.
Detailed Scoping
Finalize BoP subsystem scope, define the control logic framework, complete system-level PFDs, and initiate long-lead procurement.
Engineering Launch
Commence detailed design, finalize engineering workstreams, lock in the prototype build schedule, and establish the demonstration pathway.
12-18 Month Milestone Timeline
Program Launch
Finalize the HG-250 Phase 1 Statement of Work with Pratt Miller, complete architecture definition, down-select stack suppliers, and complete system-level PFDs.
Engineering & Commercial Advance
Launch detailed engineering, secure strategic customer LOIs, advance the demonstration site, and prepare project finance packages for the pipeline.
Prototype Initiation
Complete subsystem procurement, initiate the prototype build, finalize the control logic framework, and begin bench testing and validation.
Demonstration Readiness
Position the first demonstration unit, commence field validation toward the 5,000-hour Gen 1 target, execute strategic offtake, and reach institutional-grade readiness for the next financing.
Fuel Transition Pathway
Baseload Natural Gas
High-efficiency generation deployed immediately to solve the AI power constraint, with a lower emissions profile than the regional grid average.
Hybrid Integration
BESS integration, behind-the-meter solar, and initial hydrogen blending (up to ~25% by volume).
Toward Net-Zero
Deployment of validated HG-250 SOFC arrays and transition toward green hydrogen fuel supply, full campus decarbonization.
