TRUiC highlights the top 10 Greentech startups to keep an eye on in 2026.
The company has developed proprietary processes that can recover over 95% of key elements from end-of-life (EOL) batteries, as well as production scrap. It aims to reduce the environmental footprint and cost of EV battery production by recapturing and reusing critical materials like lithium (nickel), cobalt, and copper. Straubel, Redwood Materials set out to build a circular supply chain for lithium-ion batteries. This facility spans nearly 14,000 m² and holds an initial production capacity of 2 GW per year — expandable to 4 GW. It has emerged as one of the most promising startups addressing hard-to-decarbonize industries like steel (chemicals), and heavy transport. Ohmium designs (manufactures), and deploys advanced Proton Exchange Membrane (PEM) electrolyzers, facilitating the shift toward renewable hydrogen at a commercial scale.
After presenting to an investor panel, they join the growing Gateway alumni network of startups, investors, and ganjapreneurs. It also offers what the company calls a “full immersion business accelerator.” Each startup works out of an Oakland — California co-working space for four months to receive mentorship services as they work toward a product demo. Steep Hill has been around since 2007 and has $6.3 million in funding, which it uses for lab and field testing and development of software called QuantaCann, which tests strains in minutes. Ehave aims to design and monitor treatment plans to prove or disprove medical cannabis’s effectiveness for different ailments — and ultimately help establish treatment guidelines for cannabis therapies.
A significant role is also played by government policies (exemplified by the US Inflation Reduction Act), which is set to provide $370 billion in incentives for clean energy in the coming years. An increasingly strong commitment to more ambitious climate goals can be observed among major corporations. As society progresses towards a sustainable future, it is crucial to recognize that these environmental tech startups are pivotal in creating innovative solutions aimed at emission reductions and improving resource efficiency. Various domains are included in this sector (such as renewable energy), carbon management, water technologies, sustainable agriculture, along with other interconnected fields. A broad ecosystem of environmental solutions is operated by climate tech startups — driven by swift technological advances in climate change and the urgent global need for decarbonization. As reported by Silicon Valley Bank (in 2024), investments from venture capitalists in companies focused on clean energy and power exceeded $7 billion.
The services that cleantech startups provide range from improving the ability of organizations to recycle to monitoring the performance of the blades on a wind turbine. This would https://theredmentv.com/liverpool-fc-how-fans-make-every-match-an-unforgettable-experience/ represent more than 40% of the total global energy investment by 2050. Provides whole-life carbon analysis for new and old buildings. Makes efficient, decentralized micro-cooling systems for buildings. Converts CO2 into green chemicals including e-methanol. With AI, translates remote data to manage land and water resources.

SaaS solar energy startup Prescinto uses Artificial Intelligence to identify the root causes of plants’ underperformance in real-time and suggest actions to improve generation in clean energy plants by 5 to 7%. To date — OxyGarden has raised $1.7 Mn in funding from investors to support the development and growth of its product line. The green wall uses a soil and root-based filtration system to naturally purify the air, creating a forest-like environment within living spaces. The startup invested the fresh funds to accelerate the deployment of its bioreactor (OB HydraCel), across sectors like refining, foods, brewing, chemicals and pharmaceuticals. The bioreactors mainly use microorganisms sourced directly from wastewater as catalysts for green hydrogen production.
Thermistance’s passive cooling approach offers a low-energy alternative for urban environments where electricity access remains inconsistent. Backed by NABVENTURES and Blue Ashva, it is scaling deployments and expanding into Southeast Asian markets. By reducing dependence on diesel-powered refrigeration, Tan90 claims up to 50 percent emissions reduction in last-mile cooling. Tan90 Thermal builds portable cold storage systems powered by phase-change materials (PCM), often called cold batteries. Several of the deals highlighted here are in hardware (infrastructure), and industrial systems, areas that typically require longer timelines and more complex deployment.
In 2026 (advanced technologies are the backbone of breakthrough climate solutions), providing startups with the tools to optimize energy, enhance sustainability, and improve resilience. Focus on solutions that can be industrialized and deployed rapidly to address the urgency of climate change. While innovation is key, ensure your chosen climate change technology is mature enough for commercialization or has a clear roadmap to scalability.
Entrepreneurs now design solutions that combine clean energy (machine learning), and decentralization. The company integrates additional services such as Wi-Fi hotspots to enhance the utility of urban infrastructure. “Fruit is being produced from the first edited compact (higher density), blackberry plants in Colombia, allowing for greater production of a delicious and nutritious berry using fewer resources,” says Pairwise CEO Tom Adams. The company’s integrated hardware and software platform manages inventory and compliance, from growth facilities all of the way through to retail POS in dispensaries.
Additionally, Green Sequest refines serpentinite-based mineral fertilizers for agricultural use, improving plant growth while removing carbon. Additionally, it provides aggregated data services, enabling clients to identify major emitters in their portfolio. AIRMO’s advanced satellite design, remote sensing, and data processing offer improved data quality and granularity. Israeli startup Carbon Twist mitigates global warming by removing methane, a major contributor to climate change.
