Prometheus
Prometheus, founded in 2018 in Santa Cruz, has raised approximately $24.1 million (across reported rounds in 2020–2021) and achieved a $1.5 billion valuation as of September 2021. Key investors include BMW i Ventures, Maersk Growth, and Metaplanet. The company captures atmospheric CO₂ and converts it into carbon-neutral gasoline, diesel, and jet fuel using renewable energy and advanced electrochemical methods. With growing interest from the shipping and aviation sectors, Prometheus is positioned to provide cost-competitive, zero‐net‐carbon alternatives to fossil fuels, part of a broader climate-tech wave.
