Solutions for the CO2 capture They are at the center of the debate on the energy transition and the fight against climate change. The pursuit of climate neutrality requires measures to reduce and offset greenhouse gas emissions, with carbon dioxide being the main focus. Spain, unlike other major European economies, faces significant regulatory obstacles that hinder the development and implementation of these technologies.
The absence of a specific regulatory framework In our country, this represents a competitive disadvantage for sectors that are difficult to decarbonize, while also limiting access to European funds aimed at promoting innovations in carbon capture, utilization, and storage. This is indicated in a report prepared by the Naturgy Foundation and directed by Mariano Marzo, emeritus professor at the University of Barcelona.
The role of carbon capture in the energy transition
The carbon capture, utilization and storage technologies (CCUS) are essential to meeting international commitments to reduce emissions. According to the International Energy Agency (IEA), achieving climate goals requires capturing between 7.000 and 14.000 billion tons of CO2 each year until 2050. These tools are especially relevant in industries with hard-to-abate emissions, such as cement, steel, and chemical production. To learn more about the advances and challenges of these technologies, see This analysis of progress and challenges in CO2 capture.
The Naturgy Foundation report points out that the massive adoption of CCUS technologies It is key not only for industrial decarbonization, but also to promote new value chains, such as the production of green hydrogen y low-carbon fuels.
Innovation and international collaboration are emerging as essential conditions for the deployment of these solutions. The report warns that urgent action is needed in response to current CO2 levels in the atmosphere and urges governments to support those already taking action.
Pioneering projects and initiatives in CO2 capture and use
Initiatives such as The Robla Green In León, a complex that combines a biomass cogeneration power plant and a CO2 capture plant that aims to process 400.000 tons of biogenic CO2 annually. This COXNUMX is used for the synthesis of green e-methanol, a fuel with a zero-carbon footprint and applications in multiple industrial sectors, as well as for export via sustainable rail networks.
The project also integrates hydrogen generation through electrolysis powered by renewable energy, and direct collaboration with farmers to use corn waste as a raw material, promoting sustainable and efficient agricultural management. Both the industrial experience and the technical involvement of specialized consortia (including Mitsubishi Heavy Industries and Siemens) position La Robla Green as a European benchmark in the integration of CO2 capture, clean energy, and the circular economy.
Similar solutions in Europe, such as Heirloom plants in the United States, demonstrate the feasibility of systems capable of directly extracting atmospheric CO2 and safely storing it underground. Other approaches rely on biotechnology, using bacteria such as Bacillus megaterium to efficiently transform CO2 into limestone, with potential applications in the construction industry and in reducing the footprint of traditional materials.
European regulations and certification standards
Faced with the proliferation of carbon capture projects, Europe has taken steps forward by approving regulations such as the Regulation (EU) 2024 / 3012, which introduces a common framework for the certification of CO2 removals and expands the range of recognized ecosystems and techniques. This standard covers both geological and marine captures, agricultural and long-life products, driving investment and innovation across the carbon value chain. To better understand how these standards support the transition, you can visit .
Certification standards seek to ensure the additionality and permanence of the absorptions, establishing precise criteria for the measurement, verification and recording of carbon credits. Preventing “ecoposturing” and providing legal security Both developers and credit buyers are priority targets of this regulatory framework, which is already inspiring pioneering initiatives in Spanish regions such as Andalusia.
Towards a low-carbon economy: synthetic fuels and emerging technologies
The synthetic fuels (e-fuels), obtained from green hydrogen and captured CO2, represent another way to close the carbon cycle in sectors such as transport or aviation. Pilot projects such as Petronor's in Bilbao consolidate the role of captured CO2 as a strategic raw material, anticipating a transition towards fuels with net zero emissions compatible with existing infrastructure. To learn more about these initiatives, see the main trends in reducing carbon emissions.
The industry is also making progress in the development of bioreactors and techniques genetic engineering that allow for efficient and clean carbon capture, utilizing industrial waste and maximizing the durability of the solutions. Despite the technical challenges, the integration of renewable energies and the circular economy predict a promising future for these emerging technologies.
Sustainability and social benefits must be priorities in any capture initiative, ensuring that projects generate added value for communities and contribute to improving ecosystems. Private financing and institutional support converge to give solidity and realism to the transition toward a decarbonized economy.
