Europe's ambition to tackle climate change has gained significant momentum with the advent of an innovative maritime vessel specifically designed to transport and sequester carbon dioxide beneath the North Sea. This initiative, spearheaded by the Greensand project, aims to bury 400,000 tonnes of CO2 annually in its first phase, with aspirations to escalate this capacity to 8 million tonnes by 2030.

Launched in a ceremony on May 14, 2025, at the Royal Niestern Sander shipyard in the Netherlands, this vessel marks a pivotal advancement in carbon capture and storage (CCS) technology. Unlike traditional cargo ships, it is engineered to transport liquefied CO2 extracted from industrial emissions to permanently designated geological storage sites beneath Danish waters. This initiative is not merely a theoretical exercise but a fully operational industrial solution, having secured final investment approval in December 2024.

The technical complexities associated with transporting CO2 are considerable. To facilitate transport, CO2 must be liquefied at -50°C and compressed to 7 bars, necessitating sophisticated isothermal reinforced tanks alongside advanced thermal regulation systems. The shipyard applied extensive knowledge accrued from constructing methane and chemical carriers to overcome challenges like preventing acidic CO2 corrosion and ensuring cargo stability in turbulent seas.

Denmark is strategically positioned as Europe's carbon storage leader, leveraging its abundance of well-mapped depleted oil reservoirs and progressive energy policies. The Danish public has demonstrated a notable acceptance of carbon storage technologies, which has streamlined administrative processes and paved the way for robust partnerships. The CO2 will be injected at the Nini West platform, utilising geological formations known to have safely contained petroleum for millions of years, thereby fostering confidence in their capability for effective CO2 containment.

Greensand is part of a larger framework of carbon capture and storage initiatives emerging across the continent. With over €140 million in investments from the private sector and public European funding, this project encompasses not just the specialized vessel but also port facilities and long-term storage monitoring systems. It is complemented by efforts such as TotalEnergies’ Northern Lights project, which is successfully storing CO2 at depths of 2,600 meters beneath the seabed off Norway’s coast. The Northern Lights initiative is expected to increase its storage capacity to over 5 million tonnes annually by 2028, highlighting the accelerating pace of CCS developments in the region.

The growth of carbon capture infrastructure in Europe also features other noteworthy projects, including Norway’s Longship and the UK's Northern Endurance, which also aim to bolster the continent’s ability to mitigate greenhouse gas emissions. What sets Greensand apart is its dedicated land-to-sea carbon transportation model, reflecting a significant innovation in the sector.

This evolving strategy underscores a paradigm shift in carbon management—conceptualising CO2 as a product that can not only be captured but also effectively transported and sequestered. The initial goal of 400,000 tonnes annually may seem modest against the backdrop of Europe’s total emissions, yet it represents a critical stepping stone towards the ambitious 2030 target of 8 million tonnes. Should these initiatives succeed, Europe could cement its role as a global front-runner in carbon capture technology, potentially transforming traditional fossil-fuel infrastructures into vital assets for addressing climate change while simultaneously fostering economic activity.

As the Greensand vessel embarks on its operational journey, it encapsulates a pragmatic European response to climate challenges—utilising existing maritime expertise, repurposing geological assets, and crafting innovative solutions for efficient carbon management. The implications of such pioneering initiatives not only signify a proactive approach to climate action but also herald a new chapter in the pursuit of sustainable industrial practices across Europe and beyond.
