The fight against global warming is no longer limited to simply reducing what we emit from smokestacks; now the great challenge is cleaning up what we have already released. It should be noted that the current rate of decarbonization does not appear sufficient to meet international commitments, which has prompted scientists and companies to seek solutions. direct CO2 capture that until very recently would have sounded like science fiction to us.
In this complex scenario, Spain is positioning itself as an exceptional testing ground, leveraging both its privileged geographical location and the talent emanating from its universities. There is an urgent need to find the right balance to achieve the 
The potential of the ocean as an artificial lung
Researchers at the University of Las Palmas de Gran Canaria have focused their attention on the sea, which, after all, covers most of our surface. The proposal of Marine carbon dioxide removal is a necessary tool to complement renewable energy sources. Ultimately, it's about harnessing the planet's own biological cycles to accelerate carbon sequestration, which nature already performs on its own, but which needs an extra boost.
Innovations in direct atmospheric capture
But not everything is happening on the high seas; on land, the advances are equally promising. At the Universitat Jaume I in Castelló, they have taken a giant leap forward by patenting a system that uses innovative salts to capture polluting gas directly from the air. Unlike traditional methods based on amines, which tend to degrade quickly, this new material is fully electrified with clean energyThe underlying idea is to standardize these facilities so that they can be replicated internationally, thereby reducing the economic risks that often deter companies from investing in sustainability.
Transforming waste into an industrial resource
What makes these technologies truly interesting is that the captured carbon dioxide doesn't always have to be a nuisance that needs to be buried. It can be reused as a raw material for manufacturing sustainable aviation fuels or chemical products, thus closing a circle that was previously broken. This economic aspect is fundamental, as it allows investment in decarbonization to generate tangible benefits beyond the obvious environmental relief.
Furthermore, we must not forget the tax pressure coming from Europe, which increasingly penalizes greenhouse gas emissions. To prevent industries from seeking refuge in countries with more lenient regulations, it is vital to offer local solutions that allow manage carbon efficiently and competitive. It is a combined strategy where clean energy and radical engineering work hand in hand to avoid exceeding that critical temperature limit that would jeopardize our way of life.
The path to a future with less pollution inevitably involves combining all these technical and biological solutions, which act as a safety net. The development of new chemical absorbents in Castelló, together with ocean management proposals in the Canary Islands and the industrialization of filtration plants throughout Europe, paints a rather promising picture for tackling the greatest environmental challenge of our time.
