Nellie Technologies is a climate tech company developing bioengineered carbon dioxide removal (CDR) systems using proprietary microalgae photobioreactors to capture CO2 from air and point sources, converting it into biomass, biochar, and biogenic aggregates for permanent sequestration.[1][2][3] It serves agricultural and construction supply chains by providing sustainable carbon removal solutions, including verified Carbon Dioxide Removal Certificates (CORCs) available for purchase, while addressing climate change through scalable, cost-effective technology.[1][3] Operational since 2022 from sites in Wales, UK, the company removes 100 tonnes of CO2 annually, with growth evidenced by awards, nominations like the 2025 Earthshot Prize, and a first hybrid direct air capture (DAC)/bioenergy with carbon capture and storage (BECCS) site in South Wales.[3][4]
Founded in February 2022 by Stephen Milburn, a physics graduate from Bristol University, Nellie Technologies emerged from Milburn's diverse entrepreneurial background, including ventures in Japanese cuisine and software development.[4][6] The pivotal idea sparked during a software project for a Swedish industrial client facing emissions challenges, leading Milburn to realize microalgae bioreactors could accelerate carbon capture via photosynthesis.[4] Incorporating patented processes for rapid microalgae growth—fast-tracked via the UK IPO's Green Channel—the company quickly scaled from concept to operations, achieving early traction with a pilot site and 100 tonnes of annual CO2 removal locked into biochar for over 1,000 years.[3][4]
Nellie rides the surging demand for durable CDR amid net-zero commitments, where direct air capture and biochar sequestration are critical to offset hard-to-abate emissions in agriculture and construction—sectors contributing ~24% of global GHGs.[1][2] Timing aligns with 2020s policy shifts like EU CBAM and UK carbon markets, plus falling CDR costs (projected < $100/tonne by 2030), favoring bio-based solutions over energy-intensive chemical DAC.[3][4] By influencing ecosystems through scalable pilots, award recognition, and CORC sales, Nellie accelerates bioeconomy ventures, bridging startups with industrial buyers and validating organic CCUS as viable for gigatonne-scale removal.[1][5]
Nellie is poised for expansion with its first DAC site operational and CORC shop live, targeting multi-site scaling amid 2025 award momentum and rising CDR demand.[3] Trends like AI-optimized bioreactors and biochar mandates will boost efficiency, while partnerships in ag/construction could drive revenue beyond credits. Its influence may evolve from UK pioneer to global player, humanizing CDR through accessible tech—echoing its sushi-to-sequestration origin as proof that unconventional paths fix the climate.[4]
