Prometheus
We remove CO2 and water from the air and use electricity from solar and wind power to turn them into zero net carbon electrofuels. These are gasoline, diesel, and jet fuels that work in existing cars, trucks and planes without requiring modification of their engines, and don't contribute to global warming because they don't add any new CO2 to the atmosphere. Each gallon of our electrofuels means a gallon of fossil oil left in the ground forever. Importantly, these fuels for the first time can co

sourcePrometheus is classified as AI infrastructure from source descriptions and fund-directory context. Similar companies below are ranked from offline product facets and meaningful description overlap; category and source affiliation can only strengthen an existing product match. For lookup-created rows, the profile starts as pending enrichment until deeper source collection runs.
Local clusters rerank extracted product concepts and description terms. The generated graph remains the fallback for sparse descriptions: offline reciprocal product-similarity graph: extracted concepts + description terms + bounded category/affiliation boosts. Minimum fallback score: 0; max competitors: 6.

CO2Stats
match 49CO2Stats aims to help website owners understand the electricity usage and related carbon emissions associated with site usage, and then helps site owners manage their carbon footprint. The company calculates the greenhouse gas footprint of visits to your site, based on locations of your visitors and servers, computer types, window and monitor sizes, local fuel mixes, download sizes and times. Every month CO2Stats purchase Green-E certified Renewable Energy Certificates to offset your site's CO2

Duranium
match 46China and Russia control the world’s critical minerals. We can produce Titanium, Magnesium, Aluminum, Zirconium & Hafnium in the U.S. more profitably than any existing process, and carbon neutrally via co-production. Carbochlorination is the primary process for producing critical metals like titanium, hafnium, and zirconium, and was once the standard for magnesium. The problem: conventional carbochlorination relies on purchasing carbon feedstocks, wastes valuable byproducts, and is highly CO₂-in

Carbon Crusher
match 46We are crushing roads in need of maintenance, reusing the old road materials, replacing heavy oil with carbon binding lignin. This is both a cheaper, more durable and net carbon negative method, removing ~1.5 tonnes CO2 from the atmosphere from every 100 feet of road. We offer Crushing As A Service (CRAAS) to public and private road owners and refurbishers, and are already gaining international traction. Using satellite imagery, we will monitor road status and potential, and will offer additiona

Noya
match 44Noya is radically reducing the upfront capital costs and installation time required to perform direct air capture. We're doing this by retrofitting existing pieces of industrial equipment like cooling towers and turning them into CO2 capture machines.

Icarus
match 41Icarus is building the modern-day U-2 spy plane. Our autonomous solar aircraft fly at 60,000 feet for weeks at a time, eventually months and years, above weather and below satellites. They deliver persistent intelligence and connectivity for the military at a fraction of the cost of existing systems. The stratosphere is the forgotten frontier.
