CO₂ methanation (e-fuels / power-to-gas)
The Sabatier reaction (CO₂ + 4H₂ ⇌ CH₄ + 2H₂O) converts captured CO₂ and green H₂ into synthetic natural gas at a 97% single-pass-equivalent conversion (real plants stage several adiabatic beds with intercooling to reach this; lumped into one reactor here), then a cooler and knockout drum condense the reaction water from the SNG — the e-fuels loop that closes the loop on captured carbon instead of just storing it.

View & openSolar + wind green H₂ → CO₂ methanation
A solar PV array and a wind turbine each compute their own electrical output from a cited irradiance/power-curve model — not typed-in numbers — and a calculator block sums the two and writes it into a PEM electrolyzer's power draw, re-converging until the electrolyzer's hydrogen output is self-consistent with the array's own physics. That green H₂ is mixed with a CO₂-rich feed (representing the rich overhead of an amine-capture loop, e.g. basf-amdea-closed-solvent-loop or mixed-amine-acid-gas-treating — captured CO₂ standing in as a feed rather than re-solving the whole capture train here) and reacted to synthetic natural gas by the Sabatier reaction, same as co2-methanation. This is the full post-combustion-capture-plus-renewable-hydrogen loop: capture the carbon, split water with sun and wind, recombine them into pipeline-ready gas. CO₂ is deliberately fed in stoichiometric deficit so the electrolyzer's own H₂ output — not an assumed ratio — sets how much gas is made; the solar/wind design point (750 W/m² POA irradiance at 45°C cell temperature; a 9 m/s wind on a 100 m rotor) is a representative midday operating point, not a time series — this is a design-point simulation, not an 8760-hour production model.
