Technology, e-Fuels & Power-to-X

From green electrons to drop-in molecules.

Methanol, ammonia, Fischer–Tropsch fuels and methanol-to-jet, we engineer the integrated chains, not just the headline reactor, so a Power-to-X project actually performs end-to-end.

How Ionect plugs in

Engineering the chain, not the slogan.

Ionect provides engineering and decision-support across the full Power-to-X chain, from green hydrogen production to synthesis of methanol, ammonia and Fischer–Tropsch fuels. We work with technology developers scaling new e-fuel processes and industrials evaluating synthetic fuel pathways, focusing on integration, heat recovery, utility design and the techno-economics of the full chain.

The Power-to-X chain

One integrated chain, five linked blocks.

  1. Step 1
    Renewable electricity
    Solar / wind / PPA
  2. Step 2
    Electrolysis (H₂)
    Alkaline / PEM / AEM / SOEC
  3. Step 3
    CO₂ source
    Captured / biogenic / DAC
  4. Step 4
    Synthesis
    Methanol / NH₃ / FT
  5. Step 5
    Product
    e-Methanol / e-NH₃ / FT / e-SAF

The hard engineering in Power-to-X is rarely in any single block. It's in the integration, heat recovery, dynamic operation under variable renewables, utility design, and the techno-economics of the chain as a whole. That's where we work.

e-Fuels we engineer

e-Methanol, e-ammonia, FT and e-methane, compared.

Four product families, each with a different chain, maturity and end-use. The right choice is driven by the offtake and the available CO₂ and renewable profile.

e-Methanol

Liquid e-fuel and chemical building block, easiest to handle of the major e-fuels.

Feedstock chain
Green H₂ + CO₂ (captured / biogenic)
Maturity
Commercial-emerging
Main use cases
Marine fuel, chemicals, MTG / methanol-to-jet feedstock
Where Ionect adds value
Synthesis loop integration, CO₂ side engineering, full-chain TEA.

e-Ammonia

Carbon-free hydrogen carrier, strong fit for long-distance transport and storage.

Feedstock chain
Green H₂ + N₂ (air separation)
Maturity
Commercial
Main use cases
Marine fuel, fertiliser, energy carrier for export
Where Ionect adds value
Chain sizing, ASU and Haber–Bosch integration, dynamic-operation studies.

Fischer–Tropsch e-fuels / e-SAF

Synthetic hydrocarbons drop-in to existing engines and fuel infrastructure.

Feedstock chain
Green H₂ + CO₂ → syngas → FT
Maturity
Pre-commercial / pilot
Main use cases
Aviation (e-SAF), heavy transport, drop-in diesel and naphtha
Where Ionect adds value
Reverse water-gas shift integration, FT loop engineering, upgrading and refining steps.

e-Methane (SNG)

Renewable methane, drop-in to existing gas grids and LNG infrastructure.

Feedstock chain
Green H₂ + CO₂ (Sabatier)
Maturity
Commercial-emerging
Main use cases
Gas-grid injection, LNG export, industrial heat

Methanation loop sizing, heat recovery, grid-spec conditioning.

We are vendor-independent, we help you choose the right product and the right pathway for the project.

Where Ionect plugs in

Six capabilities, across the e-fuels chain.

Process configuration & chain integration

Configuring the full Power-to-X chain so each block actually works with the next.

Reactor & synthesis loop design support

Methanol, ammonia, Fischer–Tropsch and methanation loops, sizing, recycle, separation.

Heat integration & utility design

Pinch analysis and utility design that turn waste heat in one block into duty in another.

Dynamic operation under variable renewables

Hydrogen and CO₂ buffering, partial-load behaviour, ramp limits and storage strategy.

Techno-economic assessment of full chains

CAPEX, OPEX and LCOX across the full chain, with sensitivities investors actually trust.

Independent technical review for FID

Third-party scrutiny of the engineering basis, vendor claims and economics ahead of FID.

Who we serve in e-fuels & Power-to-X

Two audiences, one chain-level engineering team.

For startups & innovators

You're developing a new e-fuels or Power-to-X technology.

A novel reactor, a new catalyst, a different synthesis route. We bring chain-level engineering to your pilot so the integrated system actually works, for the kind of work that HIF, EGA and DOPS-style developers are doing.

  • Pilot integration of novel reactors and catalysts
  • Scale-up engineering from lab to demonstration
  • Chain-level basis of design for fundraising and offtake
For industrials

You're evaluating synthetic fuels for decarbonisation.

Captive methanol, ammonia, or SAF for hard-to-abate sectors, shipping, aviation, refining and chemicals. We size the chain, screen the pathways, and produce the engineering and economic basis before you commit capital.

  • Pathway screening and product selection
  • Full-chain TEA against your offtake economics
  • Independent engineering basis ahead of FID
Common questions we get asked

e-Fuels project decisions, answered.

Which e-fuel makes most sense for our use case, methanol, ammonia, or Fischer–Tropsch?+

It depends on the end-use. e-Methanol is the most flexible feedstock, with established marine engines and chemical demand. e-Ammonia is the strongest carrier where you need long-distance shipping or seasonal storage and can tolerate handling complexity. Fischer–Tropsch fuels (and e-SAF via methanol-to-jet or FT) are the route for drop-in liquid fuels in aviation and heavy transport. We work backwards from the offtake, purity, logistics, certification, to recommend the pathway and document the trade-off.

How do you handle the CO₂ side of the chain, captured, biogenic, or DAC?+

By treating CO₂ as a first-class part of the chain, not an afterthought. Each source has different concentration, contaminants, dynamics and cost, point-source captured CO₂ is cheapest where available, biogenic is attractive where credible certification exists, and DAC unlocks geographic flexibility but at much higher cost today. We size the CO₂ block, the conditioning, and the buffer storage in step with the synthesis loop and the renewable profile.

Can a Power-to-X plant run economically on intermittent renewables?+

Yes, but only if the chain is engineered for it. Hydrogen storage, CO₂ buffering, partial-load operation of the synthesis loop, hybrid PPA structures, and grid backup all change the economics. We model the dynamic behaviour of the full chain and stress-test the LCOX against renewable profiles, instead of assuming a flat capacity factor.

Do you work on the full chain or only specific blocks (synthesis, BoP, utilities)?+

Both. Most engagements are full-chain, electrolysis through synthesis to product conditioning, because that's where the integration value sits. We also do scoped work on a single block, typically balance-of-plant, heat integration, or independent review of a specific reactor and synthesis loop.

What does a techno-economic assessment of a full e-fuels chain typically include?+

Process modelling and mass and energy balances across the full chain (electrolysis, CO₂, synthesis, separation, conditioning), CAPEX and OPEX, levelised cost of product (LCOX), sensitivities to electricity price, capacity factor, CO₂ price and offtake assumptions, and the resulting view on competitiveness. The output is a defendable basis for investors, partners and offtakers.

Are you tied to any reactor or catalyst supplier?+

No. Ionect is fully vendor-independent across electrolyzer, CO₂ capture, reactor and catalyst suppliers. Recommendations are made on technical and economic merit against the project's drivers, with criteria documented for transparency to your board, investors or regulators.
