Hydrogen & Circular CO₂
Electrolysers are the easy part. We follow the offtake contracts, the subsidy awards and the carbon streams that decide which projects actually reach financial close.
An industry being built backwards from a deadline.
Low-carbon hydrogen is one of the few sectors where demand is being created by statute before it exists commercially. Industrial users are told to decarbonise; hydrogen is nominated as one of the routes; subsidy is attached to close the cost gap. The build-out follows from that sequence, not from spontaneous demand.
Circular CO₂ sits alongside it. Captured carbon is both a compliance problem and a feedstock — for synthetic fuels, for building materials, for chemicals — and the projects that pair the two tend to be the ones that survive.
- Electrolyser pipelines tracked from announcement to FID
- Subsidy and contract awards, including allocation rounds
- Offtake agreements: counterparty, volume, term
- Carbon capture, utilisation and the storage that gates it
What obliges anyone to build this.
Hydrogen demand is manufactured by policy. These are the instruments that do the manufacturing, and the ones we watch move.
Industrial decarbonisation targets
Sector pathways and cluster programmes that oblige heavy industry to cut process emissions on a dated timetable.
Low-carbon hydrogen support
Allocation rounds and price-support mechanisms designed to close the gap between green and grey production costs.
Carbon pricing
Emissions trading and border adjustment mechanisms that make unabated production progressively more expensive.
Transport & storage
Pipeline, shipping and storage infrastructure — the part that turns isolated projects into a market.
Three things we keep returning to.
The only milestone that counts
Announced capacity is not capacity. We track the conversion rate.
Typical offtake term required to finance a plant
Shorter contracts rarely survive a lender’s credit committee.
The date most national strategies are written against
Which makes this decade’s consents the binding decisions.
The four stages, and where they stall.
Feasibility & consent
Site, power connection, water, planning permission and the local objection profile.
Subsidy & offtake
Allocation round outcome, price support, and a buyer willing to sign for long enough to bank it.
Financial close & build
Equity, debt, EPC contract and the construction schedule that follows.
Commissioning & ramp
Actual output against nameplate — usually the least reported and most revealing number.
The bottleneck is the buyer, not the electrolyser.
Manufacturing capacity for electrolysers has expanded faster than the projects that need them. The scarce input is a creditworthy industrial buyer willing to commit to a decade of volumes at a price that supports the capital stack.
So we spend disproportionate time on offtake: who has signed, for how much, for how long, and whether the contract survives a change of subsidy regime.
Recent notes touching this area.
Grid connection queues are now the binding constraint
Capital is no longer the scarce input in UK clean power. Access to the network is.
Reading a mandate properly before pricing it
How an obligation can be discharged matters more than its headline level.
Announced capacity versus financial close
The conversion rate between the two is the most useful number in any build-out.
Questions about this area.
If something here is not covered, email the desk directly.
Does Marvqiue cover blue as well as green hydrogen?
Yes. We follow production routes by what the policy and the carbon accounting actually permit, not by colour preference.
Do you track projects outside the UK?
Our primary coverage is the UK and Europe, with selected international projects where they set the price or the technology benchmark.
Is capture without storage covered?
Yes — utilisation routes are a core part of this area, particularly where captured CO₂ becomes feedstock for fuels or materials.
Do you publish project-level data?
We publish written analysis with the underlying public records cited. We are not a database vendor.
