Top Clean Technology Startups in 2027

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.

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.

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.

Our modular, on-site technology captures climate-changing CO2 from the air, and puts it directly into our customers' production processes. The result is a greener, cleaner and cheaper product that can help their businesses go carbon neutral or even negative.

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.

Stark Future’s mission is to lead the way towards a sustainable motorcycle industry, by reducing plastic and CO2 pollution. This will be achieved by building sustainable products that are superior to traditional technology in terms of Performance, Emotion and Design.

Our clients leverage our multidisciplinary team to accelerate projects that have the potential for high impact, whether it’s improving the human condition, increasing sustainability, or otherwise moving us collectively to an inclusively abundant future.

Seatrec’s patented energy harvesting solutions redefine the boundaries of ocean research. By tackling power challenges head-on, we open up unprecedented options for data acquisition and ocean profiling. Introducing Seatrec’s infiniTE™ float – the first-of-its-kind platform with plug-and-play sensors, powered by clean, renewable energy to solve the power limitation issues of legacy floats. The platform vertically integrates a wide range of sensors (previously impossible to mount on a float because of power limitations) with a pioneering energy harvesting system that generates electricity from the ocean’s temperature differences. Seatrec floats can profile up to 3x per day, at a depth of up to 1000 meters compared to legacy floats that profile once every 10 days. These next-generation floats can be launched from sailboats with no carbon footprint and are built for endurance, facilitating long-term, data-gathering deployments.

The Kairos Power FHR (KP-FHR) is a novel advanced reactor technology that leverages TRISO fuel in pebble form combined with a low-pressure fluoride salt coolant. The technology uses an efficient and flexible steam cycle to convert heat from fission into electricity and to complement renewable energy sources.
