Air Co., as you may have guessed, is a vodka company. Unlike most other vodkas, which are made from fermented grains like corn and potatoes, the Brooklyn-based startup uses industrial carbon dioxide and water, and only releases oxygen as a byproduct. The process is similar toSheehan met his cofounder, Gregory Constantine, over whiskey a few years ago, while the two were in Israel for a Forbes 30 Under 30 event .
"It was starting to become clear that it wasn't going to be enough just to have cheap solar," he said. While that might sound a bit roundabout, Antora has already demonstrated that it's technology is the most efficient solid-state device that turns heat into electricity on the planet. Ponec says 30% of the energy put in as heat comes out as electricity, and he sees a path towards getting that up to 50%.

Eventually, that bug led her to Rob Niven, who was just getting his idea for CarbonCure off the ground. He invited her to join him, and she set to work securing the company's first grant for about $1 million from Sustainability Development Technology Canada. One of Carbon Lighthouse's most innovative features is how it charges customers. Millstein's firm guarantees a certain dollar amount in energy savings in exchange for a fixed monthly fee. If the building owner ends up saving less than that fee, Carbon Lighthouse will make up the difference.
Hannun says there's been little innovation specific to the geothermal industry, which has kept costs high. Most companies still use drills designed for making water wells, for example. That waste isn't putting people at risk, Muller says, but it's in storage that's meant to be temporary. Plus, it's costing taxpayers"No high-level nuclear waste, or spent nuclear fuel, has been disposed of. Period," said Muller, who also cofounded the data science nonprofit Berkeley Earth. "Everybody knows it has to go somewhere." , that was supposed to be deep within Nevada's Yucca Mountain, but that plan has run into challenges.
To Latimer, one kind of better technology is geothermal — that is, using heat deep within the Earth to generate steam and power an electricity-generating turbine. It's now the focus of his startup, Fervo Energy. In fact, it's the very technology used in shale production — horizontal drilling — that gives Fervo Energy a competitive edge. By drilling wells sideways deep into the Earth, Fervo is able to access more heat to produce steam, he said.
That's the future of energy in the US, says Francisco Morocz, cofounder of the startup Heila Technologies. "If you make it mainstream, you can actually transform how the grid behaves," Morocz said. "You could have whole cities generating and storing and using the electricity created locally." In 2001, Christine Ho brought her inventive spirit to college, where, as a sophomore, she answered an ad to join a battery lab as an undergraduate researcher. She stayed on as a graduate student, studying lithium-ion cells — the ones found in electric cars and most portable electronics.
Key to Imprint's batteries is flexibility, she says, which enables them to be added to devices, such as glucose monitors, that might be bendable. The batteries can also wrap around products like EpiPens. To the grid, lowering demand is an alternative to generating more power. When a utility sees demand spiking it can either buy electricity from a supplier, such as a gas-fired power plant, or it can purchase the equivalent reduction in demand that Leap offers. The startup currently aggregates more than 100 megawatts of power, Folker said.
"How can we create a grid that's flexible and reliable?" Folker said. "That's where the idea for Leap came from." Swaminathan says so-called thermal energy storage has a big benefit over hydro: It isn't location-specific. Unlike hydro, you don't need two giant reservoirs with different elevations. When the recession hit in 2008, she left Credit Suisse and, along with her brother, founded Natel Energy — a startup that combines her knowledge of the energy industry and river ecology.
