Women and Minority Led Businesses Win Top Prizes at 17th Annual Cleantech Open Northeast Accelerator Program Awards

Boston, MA -- September 30, 2021 -- Four startup companies breaking new ground in greenhouse gas reduction and featuring women and minorities in leadership took home the top prizes in this year’s 17th annual Cleantech Open Northeast Accelerator Program Awards. The winners were Innovia GEO from Oakville, Ont., which specializes in accessible geothermal energy; Osmoses from Somerville, Mass., which performs sustainable, industrial-grade molecular filtration and carbon capture; Princeton NuEnergy from Bordentown, N.J., which has developed a novel lithium-ion battery recycling process to directly recover and regenerate used battery materials; and STAC Technology from Hellerup, Denmark, which performs large-scale heating and cooling using advanced water-vapor driven turbo-compressors.

Each of these four companies will receive $10,000 in cash plus additional in-kind services. Osmoses is also the first Carbon Sequestration prize winner, another prize worth $10,000. So they will take home $20,000. All four of these startups will go on to represent the Northeast at the virtual 2021 Cleantech Open Global Forum October 20-22. There, they will compete with emerging environmental and energy technology firms throughout the nation for the national grand prize. Innovia GEO also took home the People’s Choice Award, given by attendees at the ceremony.

Launched in 2005, Cleantech Open Northeast has served as an accelerator for 523 clean technology startups from the northeast United States and eastern Canada and is part of the world’s largest environmental technology accelerator, Cleantech Open. This year, for the first time ever, global applicants were able to participate virtually, provided they had strong ties to the northeast North American region.

“The two big themes in this year’s accelerator were diversity and environmental impact. The winning startups embody these issues, and we can't wait to see how all of the startups in this cohort develop, thrive and improve our world,” stated Beth Zonis, Senior Director, Cleantech Open Northeast, NECEC. “Each of the winners this year is putting forward heavy, hard tech solutions that can have an immense positive impact on our climate, which really helped them to stand out in an excellent field of candidates.”

A major focus in the 2021 awards was put on diversity, equity and inclusion, with 31 of the 50 initial participants featuring women and minorities in leadership. In addition, the participants received training from Browning the Green Space on how to improve their diversity and how to reach effectively into underserved communities.

Participants in this accelerator program also received specific training in how to quantify the environmental impact of their solutions for potential clients and investors.

“We seek to give them the tools that help take them from great ideas to thriving companies,” Zonis said.

Graduates of the program generate more than $279 million in annual revenue and have raised over $653 million in capital. They employ over 3,300 people and 68% of them are still active.

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 28 at the semi-finals 60 judges from across the US and around the world came together virtually to see 44 separate 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.

180 people attended the virtual finals event, including entrepreneurs, investors, business leaders and public officials. The finals judges were Brandon Blaesser of Ecosystem Integrity Fund, Alba Forns of Seeds Renewables, Jane (Jing) Ge of Vectors Angel, Dan Goldman of Clean Energy Ventures, Nneka (Uzoh) Kibuule of Aligned Climate Capital, Daniela Vargas of Social Capital, and Adam Wallen of Breakthrough Energy Ventures.

With 44 companies graduating from the 2021 Cleantech Open Northeast accelerator, there are now 523 alumni companies. In the 2021 cohort 10 are from Massachusetts, eight from New York, four from New Jersey, three from Canada, three from Italy, two from Connecticut, two from Maine, one from New Hampshire, one from Rhode Island, one from Vermont, one from Alabama, one from Virgina, one from Puerto Rico, one from Denmark, and one from France.

Beyond the four winners, two runners up (Aqualumos and Julius) and two other teams that pitched at the finals (InfiSense and Measured Air Performance) have been invited to represent the Northeast in the competition at the Cleantech Open Global Forum, bringing the total to eight that will pitch for the national grand prize. Finally, Barrio Eléctrico and Long Island Clean Water Technology were given Honorable Mention. All Cleantech Open Northeast graduating teams are invited to attend the Global Forum to meet investors and expand their professional networks.
