Top Clean Energy Startups in 2026

As a Bangalore based data science company, we develop AI-driven software applications that power R&D across a variety of domains, including but not limited to Wind Energy, Geospatial Analysis, Healthcare, and Construction.

PVcase is a next generation PV software company. Driven by engineering know-how and cutting edge development team, we change the rules when it comes to solar design operations worldwide. Our customer base extends from Europe to North and South Americas, Asia and Australia, rapidly adding new customers with every software iteration. PVcase's approach to utility scale solar layout design strives to become the new industry standard as the PV industry is forced to evolve in an environment with significantly reduced subsidies. Our focus on automation and accuracy from the very earliest stages of planning, incorporating 3D topographical data points to simulate the actual location of the solar plant, allows our customers to be able to compete for and win more projects by delivering greater yields. PVcase’s automation plug-in for AutoCAD has already been used to design over 3 GW of projects by some of the world’s largest players in solar renewable energy. With our extensive experience in the solar design industry we see other opportunities to optimize and create efficiencies in other aspects of the evaluation and planning of commercial and utility scale PV projects and have several other products in the development process.

ASPL Fusion (Agnira Sanlayan Pvt. Ltd.) is building India's first commercial neutron technology platform. Starting with BNCT cancer therapy and medical isotope production, our technology trajectory leads to clean fusion energy. Our platform addresses three massive markets: 1. Cancer Therapy (BNCT): Building India's first Boron Neutron Capture Therapy centre — a targeted radiation treatment that kills tumour cells while sparing healthy tissue. 30+ million cancer patients could benefit globally. 2. Medical Isotopes: India imports 100% of its diagnostic and therapeutic isotopes. We are building domestic production capability for Tc-99m, Lu-177, Cu-64, and 7 other critical isotopes using our Gas-Dynamic Trap fusion device. 3. Clean Energy: Our fusion technology trajectory, built on revenue-generating medical applications, leads to commercial fusion power by 2038-2040. Founded by Prof. Prabhat Ranjan (former Director, Institute for Plasma Research — India's national fusion lab) and a team of nuclear scientists and engineers. Key facts: - DPIIT startup recognition: DIPP222699 - Pragmatic four-phase development strategy generating revenue from Rung 0 - World-class advisory board including Prof. Y.C. Saxena (former Head, FCIPT/IPR) - Deep partnerships with IPR, BARC, and IREL for technology and regulatory access - Accelerator-based neutron source (2.5 MeV proton beam on Li-7 target) - Proprietary simulation IP validated against IPR experimental neutron data We are not waiting for fusion to work before generating revenue. Our near-term medical applications (BNCT, isotopes) fund the long-term fusion mission. This is the pragmatic path to fusion energy.

The Cornell Cooperative Extension of Suffolk County (CCE Suffolk) is the local branch of Cornell Cooperative Extension (CCE), a statewide community education agency established in 1917. As part of the U.S. Land-Grant University System, created in 1862 to advance public education and community development, CCE Suffolk operates under the administration of Cornell University, New York’s land-grant institution. CCE Suffolk is a subordinate governmental agency with an educational mission, structured in accordance with guidelines set by Cornell University on behalf of the State of New York. As a 501(c)(3) tax-exempt organization, it is part of the national cooperative extension system—an educational partnership among county, state, and federal governments. Each Cornell Cooperative Extension association is independently governed by an elected Board of Directors, with oversight from Cornell, ensuring that local, state, and national priorities are met. Dedicated to addressing Suffolk County’s most pressing challenges, CCE Suffolk collaborates with elected officials at all levels, government agencies, local nonprofits, and community organizations to deliver research-driven solutions. Our team of over 200 educators, specialists, and researchers works across four core program areas: 4-H Youth Development, Community Education, Agriculture, and Marine. Through our affiliation with Cornell University, we leverage world-class expertise, technology, and programming to foster a more resilient and sustainable Suffolk County.
