EU ETS
100 % application from 2027. Allowance price trending up. Every ton of CO₂ emitted on intra-EU voyages is a direct cost line.

Dos apuestas. Un único ADN de ingeniería.
willbö is an engineering company. Our services business ships vessels and industrial plants. Two of those engagements matured into products we now own, extend and offer to the market: CAPCO2, a carbon-capture system for commercial shipping, and holö, the digital platform we use internally to run every marine project.

El problema
Tres normativas. Una exposición de 8 M€ por buque.
A European shipowner running EU-fixed routes today faces three simultaneous, escalating pressures. For a single 25 000 DWT reference vessel, the combined 2025–2040 exposure is around €8 million in ETS, FuelEU and avoidable penalties. Available alternatives — new fuels, full retrofit — are expensive, slow, or incompatible with the remaining useful life of the ship.
Pressure · 02
FuelEU Maritime
Reg. 2023/1805. GHG-intensity penalties scaling to 2040. Active vessels pay today — not in some future regulatory horizon.
Pressure · 03
CII · IMO MEPC
Operational rating that degrades residual value and charter-market employability of the ship. A bad CII rating is a financial event.
La idea
Other OCCS burn more fuel to regenerate on board. CAPCO2 moves it on shore.
An onboard MEA system that regenerates on board burns roughly €205 000/year of extra HFO on a reference vessel. Those regeneration emissions are then attributed to the same vessel, eroding the regulatory benefit — the owner's net capture is less than the gross.
CAPCO2 cuts the problem at the root: regeneration heat comes from an industrial waste-heat source at the port, outside the owner's emissions perimeter. The MEA travels; the carbon doesn't.
For the shipowner, net capture equals gross. For the port, it's a new decarbonisation service. For the industrial partner, it's revenue on heat they were already venting.

Cómo funciona
Un ciclo abierto. Entre barco y puerto.
Step · 01
Absorción en navegación
During navigation, main-engine exhaust passes through an onboard absorption column. A 30 % w/w aqueous MEA solution chemically fixes the CO₂.
- Gases del motor principal
- Solución MEA 30 % p/p
- Absorción química
Step · 02
Almacenamiento a bordo
CO₂-rich MEA is stored in onboard tanks. The vessel carries a working inventory sized for the round-trip between regeneration calls.
- Tanque de MEA rica
- 850 m³ de disolución · referencia
- Registro MRV continuo
Step · 03
Regeneración en puerto
Rich MEA is discharged to a port-side regeneration skid fed with industrial waste heat. Pure CO₂ is separated and delivered at the discharge interface.
- Kit de transferencia de custodia
- Calor residual industrial
- Salida de CO₂ puro
Step · 04
Retorno y reutilización
Regenerated MEA returns to the vessel for a new cycle. CO₂ continues downstream — storage, utilisation or transport — managed by third parties.
- MEA pobre de vuelta a bordo
- El ciclo se repite
- Downstream = terceros
Frontera de negocio
willbö delivers pure CO₂ at the discharge interface. Downstream management of that CO₂ — geological storage, industrial utilisation, transport — is a separate market, served by third parties. That boundary is deliberate: it keeps CAPCO2 commercially replicable at every European port.

El piloto funcionó. Estable, reproducible, certificado por clase.
Under the PERTE Naval framework, willbö executed a batch absorption–regeneration pilot at the Port of Vigo. Bureau Veritas witnessed and certified the campaign. The rig operated stably and reproducibly — zero mechanical, hydraulic or thermal incident.

Producto 02 · Plataforma interna
holö.
The digital platform we use to run every marine engineering project.
holö is not a SaaS we sell. It's the internal workspace where willbö's engineers model, document, class-approve and hand off marine projects on a single surface — from concept through production. When you engage willbö for a marine project, you get holö as part of the delivery: shared review, revision-safe handoffs, and a class-ready documentation chain — no extra procurement.
Qué hace
Una única superficie para todo el proyecto
3D model, class documents, structural reports and production drawings — versioned, linked, and reviewed in context. Class-aware templates for Bureau Veritas, DNV, LR and RINA.
Por qué te importa
Sin cadenas de correo. Sin revisiones perdidas.
As a client, you review engineering on the same surface where it's produced. Comments propagate. Handoffs between willbö's Vigo and India teams are scheduled and tracked, not improvised.
Probada en
Cada buque de nuestro porfolio
Originated on the Evrima delivery at HJ Barreras (2021), matured on SH Vega at Helsinki Shipyard, stable core on the Juan Pablo II tuna seiner at Murueta. Every marine engagement since runs on it.

Por qué willbö crea productos
Las empresas de ingeniería también deben lanzar productos.
01 · Desde la práctica
Construidos sobre proyectos reales.
CAPCO2 and holö were born inside live shipyard and industrial work. No lab prototypes, no slide decks. Every feature traces back to a real engineering constraint we hit ourselves.
02 · Conscientes de la clase
Diseñados para los reguladores.
We work daily with Bureau Veritas, DNV, LR and RINA. Our products speak that language natively — approvals aren't a bolt-on, they're the starting point.
03 · Propiedad
La IP es nuestra.
Vigo-based R&D. No licensing locks, no white-label. We control the roadmap, the data model and the commercial terms.
Origen · PERTE Naval · PP06
CAPCO2 was engineered inside a public R&D programme.
PP06 CAPCO2 #TECNAVAL2025 — a PERTE Naval programme co-led with SOERMAR and financed by NextGenerationEU. Three years of engineering turned into the Bureau Veritas-classed product you see on this page.
Willbö was one of the Galician SMEs that led participation in the PERTE.
