# Addis Energy

> Addis Energy is a Somerville, Massachusetts climate-tech company turning the Earth's subsurface into a chemical reactor to make ammonia. By injecting nitrate-bearing water into iron-rich underground rock, its process uses natural heat and pressure to convert nitrogen into ammonia without hydrogen feedstock, added electricity, or CO2 emissions. Spun out of MIT research and paired with deep oil-and-gas engineering experience, the company aims to produce clean ammonia - a fertilizer and potential fuel behind more than 1% of global emissions - at a fraction of conventional cost.

- **Founded:** 2024
- **Headquarters:** Somerville, Massachusetts, United States
- **Founders:** Michael Alexander (Founder & CEO), Charlie Mitchell (Founder & COO), Iwnetim Abate (Founder & Chief Science Officer), Yet-Ming Chiang (Founder & Chief Strategy Officer)
- **Team size:** ~16 employees
- **Products:** Geologic (stimulated) ammonia production, Subsurface resource mapping & exploration
- **Notable:** Closed an oversubscribed $8.3M seed round in December 2025, led by At One Ventures., Won $4.5M in ARPA-E funding via the Vision OPEN 2024 program., Demonstrated in the lab that ammonia can form in hours at conditions reachable with existing drilling technology (as low as ~130C).

## Products & services

- **Geologic (stimulated) ammonia production** — A subsurface process that injects nitrate-bearing engineered fluids into iron-rich rock formations, where ferrous iron reduces nitrogen to ammonia using natural heat and pressure (roughly 130-300C and 0.25-8.5 MPa) - no hydrogen feedstock, no external electricity, and no CO2 emissions.
- **Subsurface resource mapping & exploration** — A US-wide geological mapping effort to identify iron-rich formations with the right temperature and pressure conditions for pilot field tests.

## Achievements

- Closed an oversubscribed $8.3M seed round in December 2025, led by At One Ventures.
- Won $4.5M in ARPA-E funding via the Vision OPEN 2024 program.
- Demonstrated in the lab that ammonia can form in hours at conditions reachable with existing drilling technology (as low as ~130C).
- Spun proprietary geochemistry out of MIT and assembled a founding team spanning materials science and oil-and-gas engineering.
- Projects ammonia costs of roughly $200-500 per metric ton, versus ~$1,150/t for some low-carbon routes.

## Latest updates

- **2025-12** — Raised an oversubscribed $8.3M seed round led by At One Ventures with Engine Ventures and Pillar VC, bringing total funding to roughly $17.3M.
- **2025-02** — Featured in C&EN and Chemical Engineering for its subsurface ammonia synthesis approach; running core flood tests with field rocks.
- **2025-01** — Publicly launched, introducing its geologic ammonia technology; MIT Technology Review profiled the 'Earth as a chemical reactor' concept.
