Loop Chemicals

Local Ammonia Production, Global Impact

The Product

Loop Chemicals develops clean, low-carbon ammonia for agriculture. Unlike conventional fertilizer sourced from large, centralized plants, our ammonia is produced locally using renewable energy, reducing emissions and transportation costs. Our modular plants are designed to integrate directly with bioethanol facilities, creating a circular economy for sustainable fertilizer production.

Our Mission

At Loop Chemicals, we are transforming the way ammonia is produced. Our chemical looping technology enables clean, low-carbon fertilizer production at local sites, reducing emissions and transportation costs for farmers.

By combining innovative materials, renewable energy, and modular plant designs, we aim to make fertilizer more accessible, affordable, and sustainable. We believe in building solutions that benefit both the environment and the communities that rely on it.

Technology

Our chemical looping ammonia synthesis (CLAS) technology uses a looping cycle combined with solar-thermal or renewable hydrogen energy. This approach allows ammonia to be produced without fossil fuels.

Unrecognizable Chemist With Test-Tubes

By recycling carriers, our system efficiently converts sunlight, air, and green hydrogen into ammonia while lowering energy demand and carbon emissions.

Use Cases

Sustainable Fertilizer for Local Farms

CLAS plants located near farms reduce delivery costs and emissions while providing reliable access to low-carbon ammonia, helping farmers meet sustainability goals.

Integration with Bioethanol Plants

Ethanol facilities can convert fermentation residues into renewable natural gas and hydrogen, which is then used to produce ammonia on-site. This improves the facility’s carbon intensity (CI) score and enables participation in programs such as the 45Z tax credit.
