BBC reports that the company develops very small particles that have a very large internal space and scientists explain that a teaspoon of these particles contain the same area as two tennis courts. The funding, led by Mercia Ventures and Aramco Ventures, will be used to extend the research team, as well as to expand the manufacturing capacity.

The company also aims to reduce manufacturing costs of these particles from tens of thousands of GBP per kilogram to just 25 GBP. The strategy for this objective is to manufacture these metal-based particles from affordable and abundant resources, such as magnesium and zinc.

James Stephenson, CEO of Promethean, explained that the internal surface of these particles can be engineered to absorb greenhouse gases very effectively.

The carbon-absorbing particles, which can store greenhouse gases separately, can be used in polluting industries, such as concrete and steel manufacturing, as well as in the energy sector.

A British power plant located in Yorkshire already uses a prototype based on this technology and if the testing goes to plan, we could see more of these particles implemented worldwide.

Direct air carbon capture is another technology used to capture CO2 emissions and it is one of the most employed worldwide. It implies using vacuum technologies to pull carbon emissions from the atmosphere, while filtering the clean air. The captured carbon emissions can then be used for the manufacturing of various products, such as chemicals, or stored permanently underground.

Artificial carbon capture is also known as geological carbon capture, because usually, the captured CO2 emissions are being stored in the ground or in the form of charcoal, as some startups recently started to approach the solution.
