Promethean Particles

The firm's core business revolves around its proprietary and patented continuous-flow manufacturing process. This technology overcomes historical barriers of cost and scalability associated with traditional batch production, enabling MOFs to be produced more quickly, consistently, and cost-effectively. This process allows Promethean to manufacture MOFs at an industrial scale, with a reactor production rate of up to 1,000 tonnes per year. The business model includes direct material sales, collaborative development projects with industrial partners, and feasibility services to assess the viability of new or existing MOF structures for large-scale production. The company primarily serves clients in sectors requiring advanced material solutions for energy and environmental applications.

Promethean's main products are MOFs, which are highly porous crystal structures with vast surface areas ideal for capturing and storing small molecules. Key applications for these materials include carbon capture, biogas upgrading, atmospheric water harvesting, and gas storage and separation. The company is particularly focused on using MOFs to create more energy-efficient and cost-effective carbon capture and storage (CCS) technologies compared to traditional methods. In August 2024, the company secured an £8 million Series A funding round led by Mercia Ventures and Aramco Ventures to expand manufacturing capacity and accelerate the commercialization of its MOF-based technologies.
