Direct air capture (DAC) technologies are crucial for this, and 2025 could see the emergence of new, highly efficient, and scalable materials that make this process economically viable on a large scale. Think of materials like specialized sorbents or membranes designed to selectively bind CO2 even at low concentrations.

Researchers are exploring novel polymers, metal-organic frameworks (MOFs), and other porous materials engineered at the molecular level. A breakthrough here isn't just about capturing CO2; it's about doing it using less energy, less water, and lower costs. If scientists can develop and scale materials that significantly improve the capture efficiency and regeneration process, it could unlock the potential for DAC to become a major tool in the fight against global warming, working alongside renewable energy and emissions reductions.
