CARBON AND CLEANTECH
Steel hardware for the carbon removal industry
Modular containers, silos, and skids for carbon mineralisation, direct air capture, and CCS sites. EN 1090 EXC2 fabrication and ISO 3834-2 welding under the same quality discipline that runs our NATO line. Reference deployment with a Swiss carbon mineralisation operator under NDA.

Overview
Sector brief
Carbon removal moved from pilots into commercial fleets between 2023 and 2026. Three technology families share one supply-chain need: heavy steel hardware, fabricated to a structural standard, welded to a documented procedure, painted for outdoor service, and shipped to a site that may be a quarry, a concrete recycler, a port, or a geothermal field.
The three families we are set up to serve:

Reference deployments
Switzerland, carbon mineralisation operator (NDA)
A Swiss carbon mineralisation operator (NDA) runs a growing network of storage sites across Central Europe, binding CO2 into demolished concrete that would otherwise re-enter the construction supply chain unmineralised. This is the European benchmark for carbon mineralisation at commercial scale.
We are under NDA with this operator to develop carbon mineralisation silo hardware. Project specifics, drawings, and unit counts sit under that agreement and we do not publish them. What the relationship signals to the rest of the cleantech market is the type of work we are cleared to do: structural steel hardware for a customer whose product is permanent CO2 removal, on a timeline and quality envelope that match the customer's certification path.
Compliance
Compliance and procurement path
The cleantech buyer set is heterogeneous: deep-tech startups, large industrial corporates, EPC contractors, and increasingly project-finance vehicles funded against verified carbon-removal credits. The common thread is that every site needs documentation that survives auditing by the credit issuer, the insurer, and the host-country regulator. Our default documentation envelope covers that.
- EN 1090-1 EXC2 execution for structural steel (frames, envelopes, supports, skid bases).
- ISO 3834-2 welding at production-level, the same standard that feeds our NATO AQAP 2110 line.
- ISO 9001 and ISO 14001 quality and environmental management.
- EN ISO 9606 welder qualifications (MAG 135 and adjacent).
- EN ISO 8501 Sa 2.5 surface preparation and documented paint thickness for outdoor exposure.
- EN 10204 3.1 material certificates on structural steel.
- FARO Arm Prime 10 3D measurement on critical geometry, recorded per unit.
For projects that involve flammable carrier gases, methanation by-products, biogas tie-ins, or heated sorbent systems, ATEX zoning is set by the technology integrator. We fabricate the steel envelope to the integrator's hazardous-area classification (HAC) and integrate certified penetrations, gland plates, and grounding studs to the agreed drawing.
The AQAP 2110:2017 quality system we operate for defense work overlaps directly with what a Series B or Series C carbon-removal company asks for during a hardware supplier audit. Lot traceability, weld procedure qualification, material certs, and surface preparation records are produced as a matter of course, not as a special-case deliverable.
Deployment
Typical hardware configurations
We do not publish customer drawings. The configurations below are the recurring formats we are set up to build for the cleantech sector.
Mineralisation silos and reaction vessels
Vertical or horizontal sealed steel vessels, single or multi-chamber, with feed and discharge ports, CO2 injection bosses, instrumentation taps, inspection hatches, and external structural framing. Painted for outdoor service at recycling plants and quarries.
How we work
Engagement model
Three of our four engagement models apply directly to cleantech work.
Your engineering drawings, our review and production. This is how most cleantech hardware projects are structured. Engineering-review feedback is delivered in days, not weeks, and is treated as a billable line where heavy redesign is required.
The fourth model (catalog purchase) is rarely the right fit for cleantech hardware, because nearly every project involves a custom envelope or skid base. We will still ship a standard ISO 20 ft or 40 ft as a starting envelope where that makes sense.
Lead time

Custom build to spec
10 to 16 weeks
10 to 16 weeks from engineering sign-off.
Framework call-offs
as agreed in the framework. Pricing locked, slot reserved against the production calendar.
- Hot-dip galvanizing or extended outdoor coating systems add 1 to 2 weeks.
- NDA in 24 hours from first contact where the project warrants it.
In depth
Why a defense-grade line fits cleantech
Carbon-removal hardware sits at industrial sites for 15 to 25 years, often outdoors, and is increasingly inspected against issuer requirements of voluntary or compliance credits. The steel envelope is part of the durability story for the carbon claim itself.
Our hall runs one welding standard (ISO 3834-2), one structural execution class (EN 1090 EXC2 capability), and one paint specification (Sa 2.5 with documented thickness). Switching between a defense container, a fire-rescue sanitary module, and a cleantech mineralisation silo is a process change on the shop floor, not a capability change.
