Carbon dioxide (CO2) capture is marking a before and after in the fight against climate change and the transformation of industry. From being solely a technical issue, it has become part of the debate on the circular economy, new technologies, and business innovation, and requires coordination between public agencies, companies, and research centers.
While direct emission reduction remains a priority, CO2 capture is consolidated as a complementary pillar In sectors where decarbonization is particularly complex. The challenge now lies in maximizing its efficiency and economic viability, integrating it into sustainable value chains, and, above all, preventing it from becoming an excuse to perpetuate unsustainable models.
CO2 capture technologies: advances and challenges
The development of methods for capturing CO2 relies on systems ranging from use in industrial processes to innovations in materials. Post-combustion capture It allows the treatment of waste gases from existing facilities, separating CO2 from nitrogen, and is especially widespread in the cement, steel and energy industries. direct air capture (DAC) and seawater (DOC) are emerging as solutions for removing atmospheric CO2, although their costs are still high.
One of the biggest challenges of these technologies is the energy consumption associated with the process and the safe transportation and storage of captured carbon. Some countries, such as Norway and the Netherlands, have advanced geological storage infrastructure, while in others, social acceptance and legal barriers hinder these projects.
Advanced Materials: The Rise of MOFs in CO2 Capture
A qualitative leap in efficiency is provided by metal-organic frameworks (MOFs), materials with internal nanoscale cavities capable of adsorbing large quantities of gases. The MOFs They can be custom-designed to selectively capture CO2, outperforming traditional materials. Advances in synthesis techniques and collaboration between startups and large industries have allowed MOF production to decrease costs and scale, with rapidly growing market prospects.
Prominent examples include the MOF CALF-20, which is resistant to moisture and effective even under complex industrial conditions. The integration of artificial intelligence streamlines the discovery of new variants, optimizing their properties and accelerating their implementation.
La efficient regeneration of materials, to release the captured CO2, has been achieved using methods based on light or magnetic fields, which reduces energy consumption by up to 80% compared to conventional solutions. This accelerates the adoption of MOFs in industrial applications and gives them a leading role in the fight against emissions.
Circular economy: from industrial CO2 to food production
Captured carbon is no longer just waste: New projects demonstrate that CO2 can be transformed into a useful resource in a circular economy model. In Norway, the Finnfjord AS metallurgical industry captures approximately 300.000 tons of CO2 per year and uses it to cultivate microalgae. These algae, incorporated into salmon feed, not only reduce the carbon footprint of aquaculture, but also provide essential omega-3 fatty acids and improve fish health, even reducing common parasites.
These pioneering initiatives show that the biotechnological valorization of CO2 It is viable and scalable, enabling emissions reductions to be translated into economic and social opportunities. Public financial support and international collaboration drive the development and optimization of these solutions, which aim to profoundly transform the production system.
Corporate commitment and transparency in CO2 management
Leading companies in the energy, chemical, and metallurgical sectors include managing and reducing their carbon footprint at the core of their sustainability strategies. Official certifications such as the “Calculus” seal from the Ministry for Ecological Transition They demonstrate real efforts in monitoring and reducing emissions, guaranteeing the seriousness of their commitments to customers and society.
The certification process requires rigorous calculations and validation by independent authorities, which increases trust and transparency in business practices. Organizations such as Hafesa and Tubacex have taken steps forward in this regard, integrating CO2 capture and offset actions and strengthening their position in an increasingly environmentally demanding market.
La CO2 capture is becoming established as a strategic technology, both to reduce emissions and to generate new industrial opportunities and move toward a low-carbon economy. Its success will depend on integration with other efficiency and renewable energy proposals, rigorous application of environmental criteria, and the consolidation of circular and transparent business models.
