Highest Participation in 18-Year History Amid Surge in Cleantech Innovation

and Complex Capital Environment for Early Stage Companies

$60,000 in Prizes Awarded to Cleantech Startups from

Maine, Massachusetts, New York, Rhode Island, Virginia and France


Brooklyn, NY – September 28, 2023 – This week, the global cleantech innovation ecosystem convened for the regional finals of the 18th annual Cleantech Open Northeast Accelerator Awards in Brooklyn, New York to compete for more than $60,000 in prizes and an opportunity to advance to a national finals round of competition. With nearly 50 companies competing for top prizes, this year’s competition had the highest participation of any contest in its history – a reflection of the surging momentum in innovation, entrepreneurialism, and demand for capital in the cleantech sector. 

“The graduates of the 2023 Cleantech Open Northeast cohort are the key to our future. With their hard work and focus they are combating climate change, growing the green economy, and driving environmental equity,” said Joe Curtatone, President, NECEC. “They are now NECEC's ambassadors -- leading the just and equitable transition to a clean energy future and a diverse climate economy. We look forward to continuing to be part of their journey.”

The impressive entrepreneurs in the 2023 Cleantech Open Northeast cohort are not sitting back in the fight against climate change,” said Beth Zonis, Senior Director, Cleantech Open Northeast. “This year’s competition comes at a particularly transcendent time as the urgency for cleantech solutions is evident in our daily lives. The Federal Government is rewarding various types of solutions, and many new investors are joining the cleantech space. The unique demand for cleantech innovation is really exciting.”

“Cleantech Open is proud to partner with NECEC to accelerate cleantech innovation in the Northeast,” said Ken Hayes, Executive Director, Cleantech Open. “Each year the startups impress us with their ingenuity and hard work as we help them transform their ideas into meaningful impact.”  

"Accelerators like Cleantech Open Northeast enable clean energy and climate tech innovators across the northeast to consistently punch above their weight. Cleantech Open Northeast offers programming, expertise, and an extensive network that equip climate solution innovators with the tools, skills, connections, and overall support they need to bring their critical climate tech to market, " stated Galen Nelson, Chief Program Officer of MassCEC. He continued, "Because of programs like Cleantech Open Northeast, strategic investments in innovation are accelerating Massachusetts toward our goal of net zero emissions by 2050." 

New York State Energy Research and Development Authority (NYSERDA) Chief Program Officer Anthony Fiore said, “We are proud to support Cleantech Open Northeast because its program and entrepreneurs are advancing the essential technologies needed to lower climate emissions and bring clean energy to the forefront. Reducing carbon across all sectors is possible with partnerships like this that are advancing the solutions needed for communities across New York State and the Northeast.”

The focus of 2023 was on environmental equity: fair access to climate solutions; workforce diversity; regulatory and policy advocacy; and fostering a strong climate-focused business community. This year, a record 46 companies from Connecticut, Delaware, Maine, Massachusetts, New Jersey, New York, Pennsylvania, Rhode Island, Virginia, and international locations including France and Spain graduated from the program. 

The finals judges included Spectra Asala of B-Side Ventures, Aly Bryan of Closed Loop Ventures, Henry Heitzer of Energy Foundry, Christine Martini of RenovoBlu, LLC, David Miller of Clean Energy Ventures, and Ryan Taylor of Azolla Ventures. 

The winners are Amply Energy from Maine whose software helps contractors quickly create accurate and accessible heat pump proposals for homeowners; Ellexco from Virginia offers a chemical-free, electricity-driven innovative technology to extract lithium directly from aqueous sources; SPACESENSE from France helps companies in agriculture and utilities adapt to climate change by leveraging satellite imagery intelligence 8 times faster and 16 times cheaper; and Zinco Verde from Massachusetts which has developed a process that decreases the amount of energy consumed to synthesize zinc oxide by over 95%. SPACESENSE also won the People’s Choice Award.Each of these four companies was awarded $10,000 in cash plus additional in-kind services and specialty prizes. All four of the Regional Winners se startups will go on to represent the Northeast at the 2023 Cleantech Open Global Forum in San Jose, CA October 23-26. There, they will compete with emerging environmental and energy technology firms from across the nation for the national grand prize. 

Epic Renewal was awarded the $10,000 Agriculture/Food/Land Use Prize sponsored by the Sire Foundation, WeNeW Carbology was awarded the Carbon Prize sponsored by the Sire Foundation, and Electromaim was awarded the $10,000 Water Prize sponsored by Xylem. 

The four winners were selected by a judging panel of top cleantech and climatetech investors at the virtual Cleantech Open Northeast Regional Finals. On September 27 at the semi-finals, 50 judges from across the US came together at National Grid in Brooklyn, NY to see the 46 teams make their pitch. They had previously reviewed the startups’ curriculum deliverables. The semi-finals judges selected the top six teams to have the opportunity to pitch in front of a live audience and a panel of finals judges. The semi-finals judges also selected the specialty prize winners.

Beyond the four winners, two other teams that pitched at the semi-finals Power 3D of Pennsylvania and Shred Electric Maine, and three runners-up Active Surfaces of Massachusetts, Cleonmaye Corp., and Haylon Technologies of New Jersey have been invited to represent the Northeast in the competition at the Cleantech Open Global Forum, bringing the total to nine that will pitch for the national grand prize. Since two of the teams invited to compete for the National Grand Prize at the Global Forum are not able to attend, two other teams have been invited: GreenIRR of Pennsylvania and Prezerv of Massachusetts. All Cleantech Open Northeast graduating teams are invited to attend the Global Forum to meet investors, showcase, and expand their professional networks.

Several mentors were also recognized. Lead Mentors of the Year are Tani Chen, Margarett Jolly, and David Levine. Rookie Mentor of the Year is Taiil Kim. Cheikh Dramé was recognized with a Lifetime Service Award for his incredible dedication to Cleantech Open Northeast, the startups, and the overall community.
