Energy Startups funded by Y Combinator (YC) in the San Francisco Bay Area 2024

About Oklo Inc.: Oklo Inc. (Oklo) is developing advanced fission power plants to provide emission-free, reliable, and affordable energy. Oklo received a Site Use Permit from the U.S Department of Energy, has performed successful prototypic fuel fabrication, was awarded fuel material from Idaho National Laboratory, developed the first advanced fission combined license application accepted and docketed by the U.S. Nuclear Regulatory Commission, and is developing advanced fuel recycling technologies in collaboration with the U.S. Department of Energy and national laboratories. Oklo has been featured in Time, Newsweek, Wall Street Journal, CNBC, Popular Mechanics, Wired, Architectural Digest, Hyperallergic, POWER Magazine, has been the subject of a Harvard Business School case, and is featured in the Oliver Stone documentary Nuclear, among other features.

Reach Labs is building long-range wireless power networks that deliver scalable, resilient energy infrastructure.

We are a sensor company that aims to accurately capture the behavior of high throughput fluid systems. With this information we can help improve operations while reducing spills and theft. This technology could change the way the oil and gas industry, water municipalities, and anyone dealing with high volume fluid, operates. Fleets of our proprietary lightweight hardware send raw ultrasonic data directly to our server via cellular/satellite; we then use a mix of physics equations, signal processing, and anomaly detection to determine the behavior of fluid (volume and speed) in pipes.

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 compete with fossil fuels on price - our zero net carbon jet fuel has a price of one cent per gallon less than fossil jet fuel. American Airlines ordered 10 million gallons of this fuel and we will start shipping it next year.

SINAI Technologies is an enterprise software that helps carbon-intensive companies to price carbon emissions, manage carbon taxes, and reduce emissions in the most cost-effective way.

Batteries have a big role to play in tackling the climate crisis, and it’s essential to make sure that they’re safe and reliable to operate. At Zitara, we build cutting-edge software solutions that empower companies to deeply understand their batteries, both in design and deployment. It’s all part of our work to enable a renewable energy revolution, powered by safer batteries, at a lower cost, with less waste.

Gridware provides a grid monitoring system of sensors and software for the power distribution grid. The system centers around a low-cost hardware platform that is easily and permanently deployed to power poles. The platform detects and predicts faults that ignite wildfires, expedites repairs during a power outage, and helps utilities demonstrate risk reduction to regulators through comprehensive asset health profiles.

Moxion Power manufactures mobile energy storage products and technologies, which enable last-mile electrification in industries such as construction, transportation, events and entertainment, film production and telecommunications.

Phoenix Hydrogen is building the first commodity marketplace for hydrogen. This year, $9.5B in federal grants will fund the first hydrogen grids, but this ecosystem has no marketplace. We’re uniquely able to build one because we’re already working with big utilities on a fulfillment platform: a 1000'-tall underground warehouse for hydrogen.

Evoly makes smart electric & water meters. We save a typical utility over $4M a year. Electric and water meter measure your consumption, A smart meter on the other hand not only measure it, it also send this consumption data and a lot more remotely and wirelessly to the utility. We are a plug and play, easy to install, 5 times cheaper smart metering solution. We are a B2B company and our customer are the Utilities Thanks to our software they get 24/7 view on their grid and a wide range of possibilities : - Remote meter reading - Detecting fraud - Turning electricity on and off remotely - Time of use pricing

Maverick BioMetals is a biotechnology company advancing lithium processing. The company was founded by Eric Herrera, former Department of Defense scientist, and Jesse Evans, former startup operations manager. We've developed a biological process to efficiently extract lithium from hard rock deposits. Our custom process is greener, more energy efficient, and cost effective compared to the current methods of extracting lithium. We're currently developing partnerships with mining companies to further the commercialization of our technology.
