Cosine builds electrified thermochemical reactor systems driven by high-efficiency power electronics, delivering precise, high-temperature process heat and chemistry from clean electricity, not combustion.
Industrial chemistry runs on heat, and today that heat comes from burning fuel. Cosine replaces the flame. Our platform couples an electrified thermochemical reactor with power electronics designed for it from the ground up. Smaller footprints and higher throughputs. All you have to do is plug it in.
Our proprietary reactors use magnetic induction to enhance temperature uniformity and straightforward scalability.
Purpose-built power conversion delivers clean electricity to the reactor at exactly the waveform, frequency, and power level the chemistry demands, with conversion efficiency that off-the-shelf hardware can't match.
Cosine systems scale up and scale out. Each unit's reactor and power electronics grow together to boost throughput, and identical units stack in parallel to multiply it. A plant goes from pilot skid to full production with no bespoke scale-up engineering and no years-long construction cycle.
Our power electronics take grid or renewable electricity and condition it into precisely controlled power, matched to the reactor's thermal and electrochemical requirements in real time.
Inside the electrified reactor, energy is deposited directly into the reaction zone. No flames, no flue gas, no wasted heat, just uniform, on-demand temperatures up to and beyond 1,000 °C.
The system slots into existing industrial processes, producing the same products with a fraction of the energy losses and none of the combustion emissions.
High-temperature thermochemistry sits at the core of the industries that are hardest to decarbonize. That's exactly where we start.
Electrified reforming, cracking, and synthesis for the chemical industry's highest-temperature steps.
Thermochemical conversion routes for synthetic and sustainable fuel production at industrial scale.
Efficient, flexible hydrogen production pathways powered entirely by low-carbon electricity.
Drop-in electric heat for industrial operations ready to move beyond fired heaters and boilers.
Cosine was named the 2026 Grand Final Winner of the MIT Climate & Energy Prize, taking home the $100,000 grand prize. The award, presented at Greentown Labs, recognizes our electrified thermochemical reactor platform and its potential to decarbonize industrial heat. Thank you to all the sponsors and organizers of the MIT Climate & Energy Prize for making this possible.
We're partnering with industrial operators, developers, and researchers to deploy electrified thermochemical systems. Let's talk about yours.
