## Summary

Loop Chemicals is an agricultural technology company that develops modular, distributed systems for ammonia production intended to serve fertilizer markets and, eventually, the fuel and hydrogen carrier sectors. By decentralizing manufacturing, the company aims to reduce transportation costs and supply chain vulnerabilities for farmers. Founded in 2025 by Dan Doble, Joseph Pflum, and Christopher Hendrickson, the company emerged from the Massachusetts Climatetech Studio. It raised $15 million in a July 2025 round led by ROTH Capital Partners. As of September 2026, Loop Chemicals has licensed thermochemical looping technology from Sandia National Laboratories to advance its commercialization efforts and build a prototype reactor. Competitors in the distributed ammonia space include companies such as Talusag and Shomax.
