Top Clean Technology 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.

itselectric’s curbside charging network gives residents access to EV charging where they park their car. itselectric’s network relies on tapping existing electrical infrastructure in adjacent, privately-owned buildings. In return, itselectric pays the electric utility for the power used by the charging post, and the host properties receive a portion of the revenue generated by the post. itselectric’s hardware design is based on the specific needs of residents in dense, urban neighborhoods. itselectric’s Level 2 charging posts will draw power from an adjacent private property, connecting to the host property’s electrical supply with a 240V circuit within a small-bore conduit. Our system requires no work in the street or direct interface with the utility feed, and only minimal disturbance to the sidewalk (no trenching).

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.
