Top Energy Startups in 2027

Charm Industrial is a venture-backed startup in San Francisco with a mission to reverse climate change and return the atmosphere to 280ppm CO₂ – otherwise known as pre-industrial atmospheric CO₂ concentration. To accomplish this, we’re working on both carbon removal and emissions reductions. First, we’re working on carbon removal through bio-oil sequestration. Charm uses plants to capture CO₂ from the atmosphere. We convert biomass into a stable, carbon-rich liquid and then pump it deep underground. This removes CO₂ permanently from the atmosphere, out of reach of wildfires, soil erosion and land use change. Second, we’re working on emissions reductions by decarbonizing ironmaking, which makes up more than 7% of global emissions. Come help us fight climate change — gigatons or bust!

Autonomous boats hold the same disruptive potential as autonomous automobiles. We are Canada’s first autonomous boat company, and are focused on creating new technologies to revolutionize this burgeoning industry.

Join us as we expand from energy into new sectors.

Salient Energy's zinc-ion batteries are half the cost and last twice as long as lithium-ion batteries. They also use an inherently safe water-based chemistry. This makes them perfectly suited for the large and rapidly growing grid storage market.

We aggregate federal and state geospatial datasets and regulatory documents and build AI systems to give project developers and contractors automated spatial intelligence from site selection to permitting to project development across carbon sequestration, geothermal, hydrogen, and minerals projects.

Light turns power into a platform. We help leading brands—like solar providers, automakers, and home platforms—offer embedded, branded electricity plans to their customers. Our partners are reshaping how people experience energy, unlocking better customer experiences or the full potential of products like batteries, EVs, and other smart devices. We’re bringing together the best builders in tech and energy, backed by top investors and angels. Based in Austin, TX, we’re not just building a better utility—we’re redefining what a power company can be.

Moment Energy is repurposing Electric Vehicle (EV) batteries into clean, safe, and reliable power storage for on and off-grid applications. Their goal is to accelerate the transition to renewable power. By creating a circular economy for EV batteries, Moment extends their lifetime value by using them in second-life applications. As EV batteries still have up to 80% of the capacity left at the end of their life in a vehicle, we prevent toxic battery disposal in landfills and the need to mine lithium for the creation of new batteries.

Powered through our Network Operations Center (NOC), Rodan’s Energy Intelligence Suite (EIS) enables energy teams across North America to make intelligent energy decisions, saving them resources, time, and money every day.
