Meet Our Members: Introducing Greentown’s Newest Startups of Q2 2023

Seventeen startups joined our community Q2 2023, working on innovations ranging from smart sensors for wind turbines, to energy-efficient air conditioning, to a combo of water desalination and carbon capture.

We’re thrilled to support these groundbreaking climatetech startups—let us introduce you!


Capro-X deploys a biorefining platform that upcycles organic waste to fatty-acid biochemicals that can be used in a wide range of applications. It’s participating in Year 3 of the Carbon to Value (C2V) Initiative.

Capture6, a startup selected for Year 3 of the C2V Initiative, removes carbon from the atmosphere while producing clean water and other industrial products from seawater or other saltwater inputs. 

Global Algae Innovations grows algae that capture CO2 from the atmosphere to produce protein and oil for food and industrial use. It’s part of the C2V Initiative Year 3 cohort.


C-Quester delivers a solution for carbon capture using dry granular metal carbonate (GMC) purification technology with integrated measurement, reporting, and verification. It’s participating in Year 3 of the C2V Initiative.

Cottage is making it simple for individuals to reduce their carbon footprints with green energy without increasing their bills, regardless of whether they rent or own their homes.

Eologix’s smart sensor platform allows wind turbine operators to maximize efficiency of operations by monitoring ice and temperature, measuring pitch angle, and more. 

Kauel leverages artificial intelligence to detect threats, preventing mega-risks and catastrophes that negatively impact the environment and people’s lives.

NW NA is an independent operator of extremely high-power electric charging stations (IECharge®), distributed electricity storage units (JBox®), and new micro-electricity production units (Tikaz®).


Carbon To Stone is developing a carbon mineralization technology coupled with high-value minerals and metals recovery. It’s participating in Year 3 of the C2V Initiative.

Dioxycle, a startup selected for Year 3 of the C2V Initiative, is building an electrolysis platform to convert carbon emissions into chemicals and fuel building blocks. 

enaDyne develops non-thermal plasma catalysis reactors to convert CO2 into chemicals and fuels. It’s part of the C2V Initiative Year 3 cohort.

H2PRO is introducing a novel hydrogen-production technology: E-TAC. E-TAC uses electricity to split water into hydrogen and oxygen; however, unlike conventional electrolysis, hydrogen and oxygen are generated separately in different steps—an electrochemical step and a thermally activated chemical step.

Imperium Technologies’ electrochemical solution reduces industrial heating GHG emissions by 20 percent by addressing steam systems’ failures.

TerraFixing develops a direct-air-capture technology for cold climates using zeolite-based adsorbent materials. It’s participating in Year 3 of the C2V Initiative.

Resiliency + Adaptation

Helix Earth Technologies is using technology the team developed at NASA to improve the energy efficiency of air conditioning, as well as revolutionize the industries of carbon capture and storage and pollutant capture. Helix Earth Technologies was the winner of the inaugural TEX-E Prize

SkyH2O is scaling atmospheric water generation for use in commercial, industrial, and governmental settings. 

Thola is a consumer-investment marketplace for climate-smart agricultural commodities, offering carbon-offset tokens that can be traded as NFTs for investing in organic agricultural commodities.
