Virdi raises €2.6M to commercialise CO₂-based catalysts for industrial manufacturers

Virdi (Southampton) has raised £2.2 million (€2.6 million) in a seed extension led by Odyssey Ventures, with participation from Alphatron Impact Ventures and TOP Ventures (the corporate venture arm of Thai Oil Group). The company, a spin-out from the University of Southampton (formerly ViridiCO2), develops catalysts that allow industrial manufacturers to substitute captured CO2 for fossil feedstocks in chemical production. Use of funds is technology scale-up and expansion into Asia and the United States.

CO₂ as a feedstock, not just an emission

Most carbon capture proposals end at sequestration: catch the CO2, store it underground or at sea. Carbon utilisation takes the problem one step further — convert the captured CO2 into something chemically useful, displacing the fossil-derived feedstocks that conventional chemical manufacturers buy. The commercial target includes plastics precursors, adhesives, coatings, and solvents — high-volume commodities where even a partial shift to CO2-derived feedstocks would represent significant decarbonisation of hard-to-abate industrial chemistry.

The challenge is catalytic efficiency. CO2 is a thermodynamically stable molecule; converting it into reactive chemical intermediates requires energy and a catalyst that can do the conversion selectively and repeatedly without degrading. Virdi's catalyst approach has been in development since the 2020 University of Southampton spin-out; the seed extension (described as such in sources, not a new round) suggests the core technology has reached a point where the focus shifts from chemistry validation to scale-up and market access.

TOP Ventures and the buyer signal

TOP Ventures, the corporate venture arm of Thai Oil Group, is the round's most strategically significant participant. Thai Oil is a major Thai petrochemical refiner and conglomerate — an end user of exactly the kind of industrial feedstocks that CO2-based catalysts would substitute. A corporate investor from the target industry taking an equity position implies the technology has been reviewed against real production requirements, not just academic benchmarks.

Odyssey Ventures leads the round; Alphatron Impact Ventures continues the university deep-tech pattern of climate-linked impact capital.

The expansion into Asia is consistent with the TOP Ventures relationship: Southeast Asian industrial chemistry is a large and growing market, and Thai Oil's network would provide natural access to pilot partnerships. The US expansion is a longer bet — American industrial feedstock markets are large but competitive.

The 18-month question is whether Virdi can demonstrate catalyst performance at pilot-plant scale under conditions that approximate real industrial production. Lab-to-pilot is typically where catalyst technologies either gain credibility or reveal scaling problems the chemistry doesn't reflect at bench scale.
