From waste to grid, from green H₂ to green NH₃. Process, mechanical, structural and civil engineering under one team — including 220 mtpd e-methanol and 300 mtpd green ammonia projects active today.
Renewable gases is not one market. It is four overlapping ones — and the engineering trade-offs cross between them constantly. We work across all four, which means the integration cost between H₂, biomethane, e-fuels and NH₃ is something we own.
From anaerobic digestion biogas to grid-quality CH₄. Membrane separation, water scrubbing or PSA upgrading. Compression and odorisation. Connection point to Enagás specs.
Green H₂ plus captured CO₂ to liquid e-fuels. Synthesis loop, distillation, purification. Integration with upstream electrolyser and downstream off-take.
Synthesis loop, refrigeration and storage. Integration with electrolyser turndown to handle renewable intermittency without breaking the catalyst.
Biomass boilers, gasification, district heating distribution. Civil and structural in-house, including piping insulation and route engineering.
The CO₂ side of e-fuels. We bring our maritime onboard capture know-how (CAPCO2) into the industrial side — when the CO₂ source is a biomass boiler, a cement kiln or a fermenter.
EIA, ATEX zoning, gas dispersion modelling, BREF compliance. Documentation set for autonomous community and national approval pathways.
A representative slice of what is currently under engineering.
E-methanol synthesis plant integrating green H₂ with captured CO₂. Process flow, synthesis loop, distillation column sizing, utilities, storage.
Green ammonia plant FEED with renewable-driven electrolyser upstream. Haber-Bosch synthesis loop, refrigeration, storage and load-out.
Membrane-based upgrading from anaerobic digestion biogas to grid-quality CH₄. Compression train, odorisation, injection point to Enagás network.
Biomass boiler integration with downstream energy distribution. Mechanical, structural and civil engineering scope.
District heating network design and execution support. Route engineering, thermal piping, distribution stations.
The Palencia project documented as a technical case study: scope, decisions, deliverables, calculation method.
Renewable gases is the bridge between our marine and industrial divisions. The same chemists, the same process engineers and the same structural team that scope a marine CO₂ capture skid for CAPCO2 also size an industrial CO₂ absorber for an e-methanol plant. Our hydrogen team works port-side production for shipping and inland production for grid blending without switching teams. That is the value of multi-discipline under one roof — the integration cost is internal, not on your invoice.
Membrane, water scrubbing, PSA — which upgrading technology under which feedstock and which off-take spec.
What renewables intermittency does to the Haber-Bosch catalyst, and how engineering choices upstream protect downstream operation.
Not all captured CO₂ counts the same. The four sources, what RED III says, and how we document it in FEED.
