Top Energy Startups in 2027

Groundswell unlocks a more just and clean economy by helping communities to leverage their shared purchasing power to transform markets from the bottom up. We call this Civic Consumption. Through this framework, neighborhood groups and membership organizations can jumpstart local clean energy sectors, while saving money and reinvesting in their communities. Our projects achieve three key impacts on the local level: new economic opportunity, enhanced sustainability and increased capacity for social impact infrastructure. Join us as we expand from energy into new sectors.

VORYN provides the structuring and control layer for green bond financing: An SPV framework, a standardized reporting package, and a controlled record of issuance and ownership. That gives projects a repeatable path to capital, and gives investors a clear, auditable basis to allocate funds to operating assets without taking on operational complexity.

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.

Xempla is the world’s first decision support system for enterprise asset management, designed to provide any operations and maintenance team with the tools, resources and assistance they need to make better decisions throughout the asset lifecycle. We are building the most reliable and easy-to-use EAM tool on the market, helping O&M teams thrive in an increasingly digital, data-first environment. We have recognised some of the most pressing challenges facing the industry - from a widening skill gap to an ageing workforce and shortage of newcomers into such roles, creating an urgent need to retain and transfer knowledge, coupled with the significant costs of capacity building. And we’ve made sure we’ve covered it all, so asset and facility management companies can focus on delivering positive outcomes for their customers, driving their teams forward, and growing their business.

Electric Hydrogen (EH2) is a deep decarbonization company building low-cost, high-efficiency, fossil-free hydrogen systems. Industrial sectors like ammonia and steel production account for a third of global GHGs and will require fossil-free hydrogen at cost parity to eliminate CO2 emissions. Electric Hydrogen is rethinking electrolysis from the ground up to compete with dirty hydrogen on cost and scale. The company's technology brings hydrogen solutions to industry, infrastructure, freight and beyond. The experience of Electric Hydrogen's leadership team at revolutionary clean energy companies like Tesla and First Solar makes EH2 a qualified hydrogen company to break through today’s barriers of efficiency and cost to make measurable progress toward a zero-emission industrial sector in this decade.

SkySpecs optimizes wind farm operations and maintenance through the use of autonomous robotics, data analytics, and machine learning. Wind farms have significant costs for unplanned maintenance and downtime, resulting in a loss of energy generation and revenue. SkySpecs has developed a platform called Horizon that manages the entire blade inspection and repair process. SkySpecs completely autonomous drones collect repeatable, measurable images of all four sides of all three blades in a single flight with no human input or operation. This data is processed through Horizon and a team of blade experts help prioritize repair planning with farm operators. In 2.5 years, SkySpecs has inspected over 26,000 wind turbines in 17 countries.

Sparkfund is an energy technology subscription company based in Washington, D.C. We give customers access to essential building energy functions and outcomes — like cold air, light and resilience to storm events — without the constraints of ownership, enabling them to do more energy projects, faster, and with fewer resources. We strive to create positive change by deploying solutions that are good for business and good for the planet. And we’re building a diverse and collaborative culture to help us achieve all of that.

We make analyzing the impact of energy decisions and processing energy-related investments simple. Energy analysis is at the core of everything we do. Our software products fall into three distinct, yet linked, solution areas: -- Personalized decision-making software for engaging energy customers powered by our rates, incentives and energy simulation API (PowerBill). -- Workflow automation software for streamlining incentive and interconnection application processing (PowerClerk). --Solar irradiance data and analytics that enable customers to optimize financing, operation and integration of solar resources (SolarAnywhere). Our award-winning software is used by 8 of the top 10 U.S. solar utilities, and many of the largest solar companies. We’re rapidly expanding our capabilities to enter new markets and verticals. We’re solving big data challenges, introducing new forecasting and workflow automation technologies, and enabling partners through API access to critical energy inputs.
