Healthier soil. Durable carbon removal. Biochar made in the U.S.

Tree-icon

Ember was founded in 2026 as a joint venture between Kimmeridge Energy and Chestnut Carbon. Our flagship industrial biochar facility is in southern Arkansas, leveraging longstanding relationships with our deep network of local partners to secure wood waste and rice hull feedstock.

The result? Meaningful carbon removal at scale.

University of Arkansas Research & Support

Ember Carbon is backed by the University of Arkansas, whose researchers have spent three growing seasons studying how biochar performs on real Arkansas farms.

Their multi-year field study across eastern Arkansas row crops found that biochar can help soil hold more water, with the biggest gains in rain-fed fields where every drop counts. It’s the science behind carbon removal that also works for farmers.
