Our approach

A second life for selected North Sea gas fields

Decades of exploration and production have left the Southern North Sea with something unusually valuable: knowledge. We use it to identify fields that could be suitable for permanent CO₂ storage. Not every field will qualify. Choosing the right ones is fundamental to what we do.

From capture to permanent storage

01 · At the emitter's siteCaptureThe emitter captures and conditions its CO₂.
02TransportIt travels by ship, without requiring a direct pipeline to the store.
03ReceiveOffshore, an offloading system transfers the CO₂ from the ship to the injection system.
04StoreIt is injected deep below the seabed into a permitted reservoir.
05MonitorThe store is monitored during and after injection.

Six gates, assessed together

Subsurface, wells, infrastructure, permitting, transport and commercial viability are judged together from the start. An opportunity progresses only when all six hold together.

ContainmentCan the reservoir and its seal hold CO₂ permanently?

Capacity and injectivityCan it take the volumes needed, at the rates needed?

Well integrityCan existing wells be reused or safely abandoned?

InfrastructureIs the platform and its equipment fit for a second life?

Permitting and environmentCan it be permitted, with impacts understood and managed?

Transport and commercial fitCan CO₂ reach it by ship, and does the business case hold?

Why depleted gas fields

A field that held gas over geological time is strong evidence of a working seal, and its production history shows how the reservoir behaves. It is a starting point, not a guarantee: wells, pressure, capacity and the condition of the infrastructure are assessed for every opportunity.

Why smaller stores

Large hubs are essential, and we complement them. Smaller stores widen access to storage for different locations and volumes, and each one adds to a growing portfolio.

Reuse where it makes sense

We reuse existing assets only where their condition and integrity are demonstrated. What needs replacing is replaced.

Low impact by design

Reusing existing infrastructure, and keeping emissions and underwater noise low during construction, reduces environmental impact and supports a smoother permitting process.

Safety from the start

Safety begins with choosing the right site. Every project will progress through the applicable Dutch regulatory and permitting framework.

For emitters

Storage matched to your CO₂ stream

Your CO₂ doesn't come in one size. Capturing it only delivers its full climate benefit with a clear route to permanent storage. That's why we are developing storage around different emitter needs.

Industrial site

Sea transport

Permanent storage

More freedom in location

Our stores are designed for CO₂ arriving by ship. Sites with access to a port and a CO₂ export route can reach offshore storage without a direct pipeline to the store.

Flexible on volume

Smaller stores open storage to smaller and variable volumes that don't naturally fit the largest hubs.

Room for different CO₂ streams

Different industrial processes produce CO₂ of different compositions. Rather than assuming one solution fits every emitter, our approach is being developed with different emitter requirements in mind.

Permanent and verifiable

Stored CO₂ is measured, reported and monitored during and after injection, under a Dutch storage permit.

Flexible where you need it.
Permanent where it matters.

Start the conversation early

Storage takes years to develop, and early demand shapes which stores come first. A first conversation needs only four inputs:

LocationWhere the CO₂ is captured, and the nearest port.
Indicative annual volumeA range is fine.
CO₂ specificationThe composition of the captured stream, as far as known.
Target start dateWhen you aim to start storing.

For asset owners and partners

Before decommissioning, consider a second life

The end of gas production doesn't have to be the end of an asset's useful life. Some depleted Southern North Sea fields may be suitable for permanent CO₂ storage. We work with asset owners to identify and develop the right opportunities.

It takes more than a reservoir

GeologyCan it contain CO₂ permanently?

IntegrityCan the asset and its history support a viable second-life development?

ViabilityCan it be permitted, built and run commercially?

Reuse is pursued where it makes sense, not because infrastructure happens to exist.

Timing matters

The time to evaluate a second life is before key decommissioning decisions become irreversible. Have an asset approaching late life? Let's talk before the options narrow.

For specialist partners

Storage needs expertise in subsurface, wells, offshore engineering, permitting, legal and more. We bring those disciplines together. If yours can make offshore storage safer, simpler or more effective, we'd like to hear from you.

For authorities

Every project will progress through the applicable Dutch regulatory and permitting framework, with containment, safety, environmental impact and long-term stewardship considered from the start. We welcome early dialogue.

Have an asset approaching late life?

The earlier we talk, the more options remain open.

For investors

Developing a portfolio of permanent storage infrastructure

Europe's climate policy is creating growing demand for permanent CO₂ storage, and the first generation of storage is centred on the largest clusters. Carbon Haven is developing a complementary model: a portfolio of smaller offshore stores connected to emitters by sea.

Why this model

PortfolioOne development model, applied store after store, not a company built around a single reservoir.

EvidenceDepleted gas fields come with decades of subsurface and operating data that would take a greenfield project years to accumulate.

DisciplineA structured screening process before significant capital is committed. Capital is then committed gate by gate, and an opportunity moves on only when its development case still holds.

Illustration: a CO₂ carrier at an offshore offloading system, with stores beyond

One repeatable concept, scaled as demand grows.

Where we are

An independent Dutch CO₂ storage developer, backed by private investors and supported by specialist teams in subsurface, wells, offshore engineering, permitting and legal. We are developing our first store and the foundations of the portfolio.

Experienced founders

Together, close to 60 years across North Sea subsurface, offshore project delivery, new energy development and large integration programmes. Meet the founders.
