Oxy-combustion power cycle, real supercritical CO2
Natural gas burned in near-pure oxygen diluted by recycled supercritical CO2, expanding through a real isentropic turbine — pipeline-ready CO2 with no separate capture step.
The actual dark-mode canvas (simplified for this preview — the real example's placeholder combustor inlet is an API artifact, not real physics): natural gas burned in near-pure oxygen diluted by recycled supercritical CO2, expanded through a real turbine.
Oxy-combustion with no separate capture step
Burning in near-pure oxygen instead of air means the flue gas is already almost pure CO2 — capture is a byproduct of the cycle's own chemistry, not a bolted-on absorption unit. Honest scope: this is an open-cycle v1 (the compressor's CO2 feed and turbine exhaust aren't tied together by a recuperator yet) — it verifies the near-critical compression, oxy-combustion, and supercritical expansion chain converges and delivers net power, not a bounded commercial plant design.
