What Ambient Carbon does
Ambient Carbon is a Denmark-based climate-technology company developing the MEPS (Methane Eradication Photochemical System), a patented gas-phase photochemical platform that destroys low-concentration methane from diffuse agricultural, wastewater, and biogas sources. MEPS generates chlorine on-site via electrolysis of salt water and activates it with UV LED arrays inside a closed reaction chamber, breaking methane down while recycling the chlorine and producing fertilizer as a by-product. The system is modular, housed in standard 40-foot shipping containers, and designed for non-invasive installation outside dairy barns or treatment facilities. Field trials at the Hofmansgave Foundation farm (Denmark, 250-cow dairy barn) demonstrated up to 90% methane eradication across the 4.3-44 ppm range, with prior lab results showing 98% removal at 33 ppm, 94% ammonia reduction, and 80% hydrogen sulfide (odor) reduction.
The company's commercial model centers on sale of MEPS hardware units to large dairy operators, wastewater treatment plants, and biogas facilities, supplemented by ongoing maintenance and support contracts. Commercial availability is targeted for Q2 2026, with a full-scale MEPS pilot planned for late 2025. GTM is enterprise-led: direct field sales target major dairy companies and their supplier networks, anchored by partnerships with Danone North America, Benton Group Dairies, and Arla, and reinforced by a March 2026 global partnership with Interfood, a dairy ingredients distributor operating in over 100 countries. Technology development is supported through the PERMA Project consortium with the University of Copenhagen, Aarhus University, SKOV, and Innovation Fund Denmark / EU NextGenerationEU funding.
The company is privately held, headquartered in Copenhagen, and led by CEO David Kenney alongside co-founders Matthew S. Johnson (CSO, inventor of MEPS at the University of Copenhagen) and David S. Miller (COO). It currently operates with 11-50 employees, holds a granted patent on the MEPS process, and has positioned itself around the corporate and regulatory push to address agricultural methane, which accounts for roughly 30% of global anthropogenic methane emissions and carries 84x the 20-year warming potential of CO2.

Ambient Carbon product offering
Product offeringCore offering
Ambient Carbon develops and sells MEPS (Methane Eradication Photochemical System), a patented gas-phase photochemical technology that uses salt, water, and electricity to generate chlorine onsite, combined with UV light to eradicate low-concentration methane emissions. The modular hardware units are housed in standard 40-foot shipping containers and are deployed at dairy barns, pig barns, wastewater treatment plants, biogas production facilities, and covered manure storage sites.
Product overview
Ambient Carbon offers a single unified product: the MEPS (Methane Eradication Photochemical System), a patented methane eradication technology for low-concentration sources. MEPS uses a gas-phase photochemical process combining chlorine (generated onsite via electrolysis from saltwater) and UV light in a reaction chamber to break down methane. The modular design adapts MEPS for various applications including dairy barns, pig barns, wastewater treatment plants, and biogas production plants. The technology achieves up to 98% methane removal, 94% ammonia removal, and 80% hydrogen sulfide (odor) removal. MEPS is a closed-loop system where chlorine is recycled, and generates fertilizer as a by-product.
