EU renewable energy targets EU renewable energy targets aim to increase the share of clean energy in power generation, supporting decarbonization goals and accelerating the transition to a sustainable electricity system.
CO2 storage projects are the anchor of the European CCUS strategy, representing the long-term solution for isolating captured carbon from the atmosphere. These projects focus almost exclusively on deep geological formations, primarily depleted offshore oil and gas fields and deep saline aquifers, which offer the necessary capacity, integrity, and safety characteristics.
The landscape is defined by a few pioneering, large-scale projects—particularly those in Norway and the Netherlands—that have successfully demonstrated the technical feasibility and safety of offshore injection and long-term containment. These projects are establishing best practices for site characterization, injection well operation, and long-term monitoring. The geological advantages of the North Sea basin are central to this concentration, providing vast, well-understood, and naturally capped rock structures far from densely populated areas.
The significance of these projects extends beyond their capacity. They are fundamental to unlocking the entire CCUS value chain by providing a credible and permanent sink for industrial CO2. Their successful operation is critical for building public and regulatory confidence in the technology's safety, especially regarding CO2 containment. Challenges, however, include the long and complex permitting process required under the EU’s CCS Directive, high upfront capital expenditure for drilling and infrastructure, and addressing the long-term liability question—who is responsible for the site after the operator closes it. The trend is toward developing multi-user, shared-risk storage hubs rather than single-emitter projects, to maximize efficiency and accelerate deployment.
CO2 Storage Projects in Europe: FAQs
What types of geological formations are primarily used for CO2 storage in Europe?
Storage primarily targets deep saline aquifers and depleted offshore oil and gas fields, which offer the necessary rock porosity and an impermeable cap-rock for long-term containment.
What is the main geographic advantage underpinning European storage projects?
The main advantage is the vast, well-characterized offshore geology of the North Sea basin, which provides enormous, naturally secure storage potential.
What key technical challenge do storage projects face during the development phase?
The challenge is the thorough and lengthy geological site characterization to prove the security, integrity, and long-term containment capacity of the reservoir before injection permits are granted.
