Post-combustion and process CO₂ capture, purification, and conversion into fuels, chemicals and materials, engineered as integrated systems, assessed objectively against alternatives.
Ionect provides engineering and decision-support across the full CCU chain, from CO₂ capture and conditioning to conversion into e-fuels, chemicals and materials. We work with capture-technology developers, e-fuels innovators and industrials evaluating carbon utilisation as part of their decarbonisation strategy, focusing on capture-to-conversion integration and the techno-economics of the full chain.
The engineering value in CCU is rarely in any single block. It's in matching the capture technology to the CO₂ source, the conditioning to the conversion step, and the economics to the available offtake. That's where we work.
Two decisions sit at the heart of every CCU project: how to capture the CO₂, and what to do with it. They are coupled, the right capture technology depends on the source and the downstream specification.
Mature liquid-solvent absorption, the workhorse for dilute flue gases at scale.
Adsorption on engineered solids, modular, attractive for medium-concentration sources.
Selective gas separation, compact footprint where partial pressure is favourable.
Phase-change separation or combustion in oxygen, high-purity CO₂, energy-intensive.
Capture from ambient air, geographic flexibility, much higher cost today.
CO₂ + green H₂ to methanol, methane and Fischer–Tropsch hydrocarbons.
Direct CO₂ conversion to urea, carbonates, salicylates and intermediates.
CO₂ as a co-monomer for polycarbonates and polyols.
Reaction with calcium and magnesium silicates to form stable carbonates.
Use of CO₂ in algae cultivation, greenhouses and microbial fermentation.
We are vendor-independent, we help you match the right capture technology to the right utilisation pathway for your project. CCS (geological storage) is a different pathway and not Ionect's focus; we'll flag it honestly when it's the better fit for a given source.
Structured trade-off across amine, sorbent, membrane and cryogenic options for your source.
Drying, compression and polishing sized to the downstream conversion specification.
Configuring capture, conditioning and conversion blocks to actually work as one system.
Heat, utility and dynamic integration between the CO₂ side and the synthesis side.
CAPEX, OPEX, LCOX and LCA across the full CCU chain, with honest sensitivities.
Third-party scrutiny of capture vendor claims, system design and integration choices.
We bring chain-level engineering to your pilot, so capture, conditioning and conversion actually work together, for ARK Capture-style developers, novel sorbents, electrochemical CO₂ reduction and mineralisation start-ups.
We screen capture options, evaluate utilisation pathways, and produce the engineering and economic basis before you commit, across cement, chemicals, refining, waste-to-energy and biogas upgrading.
Amine-based absorption is the default for dilute post-combustion flue gases at scale. Solid sorbents are attractive for medium-concentration streams and for modular deployment. Membranes work where partial pressure is favourable and footprint matters. Cryogenic and oxy-combustion fit specific high-concentration or new-build cases. Direct air capture unlocks geographic flexibility but at much higher cost. We screen the options against the source's concentration, contaminants, scale, available heat and the downstream specification.
It depends on the pathway and the carbon source. Captured CO₂ converted to long-lived materials or mineralised products delivers durable removal-equivalent benefit. CO₂ used in fuels typically displaces fossil carbon and re-emits on use, the climate value is in the displacement, not in storage. Lifecycle assessment, with honest assumptions about energy source and product lifetime, is the only way to answer this for a specific project. We do that work as part of every CCU study.
By matching CO₂ availability, scale, geography and offtake economics. Storage (CCS) is the right answer for very large point sources where utilisation demand is small and storage geology is accessible. Utilisation is the right answer where there is a credible product market, a value-added molecule, or a synergy with renewable hydrogen. Ionect focuses on the utilisation side; we'll tell you honestly when storage is the better fit.
Sometimes, when the product is a high-value chemical or material, or when the CO₂ source pays to be relieved of the gas. For commodity e-fuels, current economics typically rely on a combination of CO₂ price, renewable electricity cost, offtake premium and policy support. We model the full chain explicitly so the dependency on each lever is visible, instead of buried in an assumption.
Yes. Biogenic CO₂ from biogas upgrading, fermentation or biomass combustion is often the most attractive feedstock for e-fuels because of its certification status. DAC is in scope where geography, renewable supply or product premium justifies it. Point-source from cement, refining, chemicals and waste-to-energy is the largest near-term opportunity.
No. Ionect is fully vendor-independent across capture, conditioning and conversion suppliers. Recommendations are made on technical and economic merit against the project's drivers, with the criteria documented for transparency to your board, investors or regulators.
