Top Clean Energy Startups in 2027

Helping you save money and reduce your carbon emissions. GridDuck is an online dashboard connecting affordable and easy-to-install IoT sensors, clamps and switches. Our platform provides gas, water and electricity submetering, alongside the ability to automate and balance your energy consumption. We work with clients such as Abel & Cole, Deliveroo, Pepsi (potato chips side), Heineken, National Highways and many more. We also work with an increasing number of energy brokers and consultancies, on a white label basis

epilot is the eCommerce ecosystem for the energy world. We make it easier for energy providers to enter the digital world and help them take on a leading role as an energy service provider. With our SaaS platform, we enable them to sell their energy products and services online and help streamline the entire end-to-end fulfillment process to deliver an amazing customer experience. We change the way the energy world works: A world where innovations are realized in minutes rather than months and where all stakeholders collaborate in our epilot community.

Crusoe Energy is on a mission to unlock value in stranded energy resources through the power of computation. We aim to align the long term interests of the climate with the future of global computing infrastructure. As data centers consume an exponentially growing power footprint to deliver technology to all connected devices, we are inspired by making sure that the energy meeting that demand is sourced in an environmentally responsible fashion.

Evaluation of demand-side management energy efficiency programs on behalf of electric and gas utilities in residential, commercial and industrial markets. We provide hourly and fixed-cost consulting services, conduct on-site engineering visits, and meter energy-consuming equipment to verify energy savings.

Our business lines include: Aluminum, Automation, Cement/Minerals, Combustion, Cryogenics/Energy, Cutting Tools/Abrasives, Filling/Sealing, Glass, Grinding/Ultra-Precision, Induction, Intralogistics, Maintenance, Metal Cutting/Composites, Piping Solutions, Steel, Sugar/Bio-Energy, Tube/Pipe, and more. We build the plants of the future through our unrivaled spirit of innovation. We currently hold 2,113 patents in 645 families. In 2018 alone, we patented 45 new inventions and invested over $37 million dollars in R&D. We are leading the way towards Industry 4.0 and the Industrial Internet of Things (IOT).

Aeroseal is a creator of duct sealing technology aimed at lowering building carbon emissions. By sealing all the gaps in the building envelope, air ducts, and vents using the company's non-toxic, water-based compound, consumers can improve the comfort and health of their homes and workplaces while also helping to maintain a cleaner environment.

We imagine a future where sunlight continues powering solar farms and providing lighting after the sun sets. We’re a small team of engineers who make progress by building things quickly and iteratively. Time is our greatest constraint. Join us!

Mojave products have two systems inside: an innovative liquid desiccant system to manage humidity plus a modern vapor compression system to control temperature. This allows each process to perform efficiently. As a result, you get improved comfort and excellent reliability at a similar price along with lower energy and increased sustainability. Our initial product is currently in field trials. We are looking for commercial partners and building test sites. If you are a Sales Rep, please sign up to qualify to sell our equipment. If you are a building owner/operator, please sign up to beta test our equipment on your building!

Shipping containers that produce clean fuels from the two most abundant resources -- sun and seawater.

Enurgen builds DUET, a 3D physics-based software platform for utility-scale solar and battery storage. DUET simulates what a plant should produce at every timestep of a 30-year life, compares it against what the field actually did, and attributes the gap down to the individual component. Conventional monitoring can tell you a plant is underperforming — working out why is the hard part, and that's the problem we solve. Every megawatt-hour a solar plant fails to produce is one that comes from somewhere else. Recovering it needs no new land, no new panels, and no new interconnection queue — just a correct answer about what went wrong and where. The model came out of SUNLAB at the University of Ottawa, with more than a decade of research behind it. It runs across the asset lifecycle: - Design — terrain-aware 3D modelling to establish a realistic performance baseline before anything is built. - Construction — analysis from the moment equipment comes online, so issues surface before commercial operation rather than years into it. - Operations — minutely, string-level analysis with automated root-cause loss detection, separating recoverable losses from the ones that aren't and routing the fixable ones into the maintenance system. We're a small, early-stage team with an office in Ottawa, Ontario. The engineering work is heavy on data: analytical queries over fleet-scale time-series, streaming pipelines feeding live analytics, on-prem software that keeps running when the WAN doesn't, and dashboards that stay fast at that scale. Research sits at the same table as engineering, so the physics and the software get built against each other. Hybrid-first, with remote on the table for any role. Every role includes an equity grant. You don't need a solar background — the domain is interesting, our customers are sophisticated, and you'll pick it up.
