TriGen Energy is developing integrated oxyfuel power generation systems that enable oil and gas companies to monetize low quality and contaminated gas resources while producing clean power, CO2 for EOR, and other valuable products.

The company's core technology centers on a pressurized oxyfuel combustion system that can handle highly contaminated gas streams that are unsuitable for conventional power generation. By integrating air separation, specialized combustion, and CO2 processing, TriGen's solution creates value from otherwise stranded gas assets while enabling decarbonization of oil and gas operations.

The company’s flagship product is a modular oxyfuel combustion system that operates at high pressures (up to 300 bar) and temperatures (up to 1,280°C). The system combines an air separation unit (ASU) to produce oxygen, a pressurized oxyfuel combustor, and a modified gas turbine to generate power. The process yields three primary outputs: electricity, high-purity CO₂ for carbon capture and EOR, and high-quality water.

• TriGen operates on a project-based business mode
• Pricing is determined by several variables, including the quality and volume of the gas feedstock, the scale of the power plant, and the specific requirements for CO₂ compression and EOR

TriGen's oxyfuel system offers several key technical innovations:

1. Contaminated Gas Handling
   • Processes gas with up to 60-70% contamination (CO2/nitrogen)
   • Can utilize previously unmarketable gas resources
   • Handles sour gas and other difficult feedstocks
2. Modular System Architecture
   • Scalable units from 20-200MW thermal capacity
   • Standardized components for cost efficiency
   • Flexible deployment options based on field needs
3. Multi-Product Output
   • Clean power generation (30-36% thermal efficiency)
   • High-purity CO2 for EOR
   • Boiler-quality water production
   • Nitrogen for reservoir pressure maintenance
4. Integration of CCUS
   • High-purity CO2 for EOR as an effective carbon sequestration option with additional revenue for operators

• Power Generation: clean power for use in remote oilfields or for grid injection
• CCUS & Enhanced Oil Recovery (EOR): high-purity CO2 as a byproduct of oxy-fuel combustion for injection in mature fields
• Water Production: boiler-quality water as a byproduct that can be used for industrial purposes or reinjected
• Nitrogen Production: nitrogen generated during air separation can be used for pressure maintenance in reservoirs
