About Ambient Carbon

Ambient Carbon, founded in 2021 and based in Frederiksberg, Denmark, is a company focused on climate restoration by developing technologies to mitigate greenhouse gas emissions. The company's international team, which includes co-founders Matthew S. Johnson (Chief Science Officer) and David S. Miller (Chief Operating Officer), along with CEO David Kenney, combines scientific research with business acumen to create high-impact, deep-tech climate solutions.

The core of Ambient Carbon's offering is its proprietary Methane Eradication Photochemical System (MEPS). This technology was invented at the University of Copenhagen and addresses the significant environmental challenge of methane, a greenhouse gas with a global warming potential 84 times that of carbon dioxide over a 20-year period. The MEPS technology utilizes a patented gas-phase photochemical process that generates chlorine radicals from salt, water, and electricity. When activated by UV LED arrays, these radicals break down low-concentration methane in a closed-loop system, effectively mimicking a natural atmospheric process. The system is designed to be non-invasive, ensuring that operations in its target markets are not disturbed.

Ambient Carbon primarily serves the agricultural sector, specifically dairy and meat producers, which are responsible for a substantial portion of global anthropogenic methane emissions. A recent large-scale field trial at a 250-cow dairy barn in Denmark successfully demonstrated that the MEPS unit, housed in a standard 40-foot shipping container, can eradicate up to 90% of methane from ventilation air. Beyond methane, the system also removes ammonia and other odors, and it produces fertilizer as a byproduct, which can help reduce operational costs for farmers. The company also targets methane leakage from wastewater treatment plants and biogas production facilities. Ambient Carbon plans for a commercial launch of MEPS in the second quarter of 2026, scaling globally through distribution and manufacturing partnerships.
