District Heating
District heating CO₂ capture near homes and schools must be efficient, quiet and safe. With Galloxol® CCU, you turn stack CO₂ into a clean, metered stream you can pipe to local users, liquefy for trucks, or send to storage, lowering reported emissions while creating new revenue.
How It Works
Step-by-step
Capture CO₂ at CHP/boilers while reclaiming heat to the network. The steps show how we condition flue gas, capture clean CO₂, align buffers to daily load shape and, if needed, liquefy for compact storage.
Source the CO₂ (CHP/boiler exhaust)
We take CO₂-containing flue gas from district-heating CHP or boilers and route it to the capture train. Inlet sizing matches temperature, flow and sulphur/chloride load for steady operation.
Quench & condense (recover heat to the grid)
Controlled quench protects equipment; condensers remove moisture/acid vapour and return sensible/latent heat to hot-water loops or heat exchangers, improving overall plant efficiency.
Capture & purify (clean product CO₂)
Galloxol® selectively absorbs CO₂ and rejects non-CO₂ gases. The product stream is dried and trimmed (low O₂/particles) for internal use or adjacent industry.
Buffer storage (follow daily load shape)
Gas buffers ride through morning/evening peaks and changeovers. Online analysers and auto-divert protect specification; batch-aligned logs simplify compliance.
(Optional) Liquefaction & compact inventory
Condense CO₂ to liquid where footprint is tight or transfer between plants is needed. Insulated tanks provide predictable inventory across seasons.
Distribute & partner use
Feed internal uses (pH control, inerting) or load to tankers for local partners (food, construction materials, e-fuels). On-site CO₂ reduces delivery risk and stabilises costs.

Yield impact
Up to 99% product CO₂ purity
We engineer the product stream to ≥99% CO₂ with very low moisture, protecting downstream equipment and meeting the QA needs of local users (pipeline, liquefaction, or storage). Because Galloxol® has zero vapour pressure, there’s no solvent carry-over into the CO₂, supporting use near residential areas and food-adjacent applications.
Inline purity/moisture instrumentation provides timestamped, audit-ready reports per outlet, keeping compliance and contracts straightforward.

Benefits
Benefits of Galloxol® in District Heating
These benefits translate the technology into day-to-day gains, lower energy per tonne, fewer stoppages, stronger QA, and options to monetise surplus CO₂.
Lower reported emissions
Converting stack CO₂ into a metered product stream turns abatement into hard numbers. You move from estimated factors to measured tonnes with continuous mass balance across capture, routing and losses.
Automated summaries feed compliance and ESG reporting on a fixed cadence, so year-on-year reductions are traceable, comparable and audit-ready without manual spreadsheet work.
We include MRV-ready mass balance (stack → capture → outlets → losses) with calibrated meters and auto-generated reports, so ESG teams can file scope-1 reductions without manual spreadsheets. Where cities require verification, the data pack (QA, timestamps, totals) supports third-party audits and annual assurance with minimal extra work.
New income stream
Captured CO₂ becomes a sellable product: pipe to nearby users for steady offtake, liquefy surplus for regional customers, or allocate a share to permanent storage where credit schemes exist.
Commercially, clear custody transfer points and pricing per outlet let you diversify revenue beyond heat sales and hedge against seasonal demand swings.
We help model an outlet mix (local pipeline, liquid sales, storage credits) against regional price indices and logistics so revenue is diversified, not single-buyer dependent. Buffers are sized to smooth sales cadence (daily/weekly draws), and contracts can be backed by per-batch QA certificates for consistent pricing and fewer disputes.
Community-grade safety
Galloxol® is non-hazardous and has zero vapour pressure, so there’s no solvent carry-over to air or to the CO₂ product, well suited to dense, residential locations.
Engineering controls, acoustic enclosures, silencers, containment and leak detection, are designed in from the start to meet local standards and smooth the permitting and neighbourhood-acceptance path.
Galloxol®’s zero vapour pressure means no solvent emissions under normal operation; secondary containment, controlled drains and gas-tight enclosures further reduce environmental risk. A site-specific HAZOP/LOPA and ERP tie into your utility’s procedures, while acoustic treatments and screened layouts keep neighbourhood impact low.
Predictable OPEX
Heat-integrated regeneration and low-pressure operation keep energy use steady, so cost per tonne is forecastable across seasons and tariffs. There are no solvent vapour losses to chase.
Choose HIGH-temp (~140 °C) when maximum capture and energy efficiency matter most, or LOW-temp (~95 °C) to reuse available low-grade heat and limit exposure to electricity price volatility.
Energy is dominated by regeneration heat and compression work; both are stabilised with heat integration and sensible pressure ratios. Choose HIGH-temp (≈140 °C) when you prioritise capture efficiency; choose LOW-temp (≈95 °C) to reuse available network heat and hedge power-price volatility, keeping €/t steady across seasons.
Modular capacity, minimal disruption
Capacity grows with standardised skids that slot into planned tie-ins, so expansions are short-outage projects rather than major rebuilds. Day-one training and SOPs remain valid as throughput rises.
Shared spares, common HMIs and unchanged alarm classes keep maintenance simple and lifecycle cost low, protecting the operating discipline you’ve already established.
We plan tie-ins, lifting routes and clearances during the first install so additional trains drop in with short outages and no major civil rework. Standardised HMI, alarm classes and SOPs mean no retraining cycle as capacity scales from pilot to multi-thousand kg CO₂/h, spares and documentation stay common.
Flexible outlets with clean accounting
Split flows across pipeline, liquefaction or storage and track each with calibrated meters, purity/moisture QA and timestamps for custody transfer.
That dataset supports contracts, invoicing and credit issuance without extra admin, each tonne is traceable from stack to outlet, keeping regulators, auditors and buyers aligned.
Each outlet (pipeline / liquid / storage) gets its own custody-grade metering, QA sampling and timestamped batch logs, so billing and carbon-credit claims are traceable and defensible. An API or export to your billing/ESG tools keeps finance and sustainability teams aligned without duplicate data entry.

Below you’ll find quick answers to the questions we hear most, from feed-gas limits to maintenance routines. Expand any item for details; if you don’t see your question, our engineers are one click away.
All frequently asked questionsYes. Galloxol® uses a non-hazardous, biocompatible solvent with zero vapour pressure, so there is no solvent carry-over into the product CO₂ or the surrounding air. That property eliminates the fugitive-emission concern you’d have with volatile chemistries and simplifies the safety case for urban sites.
For siting in residential areas, the package includes acoustic enclosures, silencers, and clear access/lifting plans. We place equipment to minimise line-of-sight noise and visual impact (e.g., behind existing buildings or screens) and design secondary containment and drain management to meet local environmental expectations. A HAZOP/LOPA (site-dependent) and startup procedures are provided to align with your utility’s safety management system.
Not necessarily. Many producers start by piping CO₂ to nearby users and add a liquefier once volumes justify the CAPEX. We design tie-ins and control points up front so a liquefier drops in later with a short outage and without reworking the capture controls.
When you add liquefaction, we scale tankage to your shipping cadence and install custody-grade metering and batch QA. That staged approach lets you prove €/t and uptime first, then expand into regional sales at lower risk.
Where a recognised framework and storage partner exist, routing a portion of captured CO₂ to permanent storage can earn credits. To support claims, we provide metered splits (pipeline / liquid / storage), mass-balance reporting, and QA logs (purity, moisture, timestamps) as part of an MRV-ready data pack.
Practically, we work with your team to define the baseline, the fraction stored, and any chain-of-custody documentation the registry requires. That way, sales to local industry and storage for credits can run in parallel without complicating day-to-day operations.
The system is delivered as modular skids with compact footprints suitable for urban plots. We plan equipment placement, walkways, and craning routes up front so installation and future maintenance are straightforward. Enclosures and acoustic treatments are selected to meet your local noise limits, and we position intakes/outlets to reduce propagation toward sensitive receptors.
If the site prefers a clean street view, we can package major components in low-profile housings or behind existing structures. The layout includes service clearances, drain/utility tie-ins, and screening to satisfy both engineering and neighbourhood expectations.
OPEX is driven mainly by regeneration heat and compression work. With heat-integration and sensible compressor ratios, specific energy per tonne is predictable. Where low-grade heat is available (CHP/district heating), the LOW-temp configuration further reduces exposure to electricity price swings.
Maintenance focuses on filters, pumps/compressors and instrumentation. The solvent has no vapour losses, so there’s no continuous top-up for evaporation. We provide planned-maintenance intervals, a critical-spares list and remote monitoring hooks so your team can manage the plant inside normal shift routines.
