Sixteen startups joined our community in Q4 2023, working on innovations as diverse as low-emission steel production, hydrogen electrolyzers, and lightweight, flexible solar panels.
We’re thrilled to support these groundbreaking climatetech startups—let us introduce you!
Agriculture
Clean Crop Technologies’s proprietary Clean Current technology combines food-grade gasses and electricity to remove contaminants from seed and food surfaces, improving food safety and reducing food waste.
Electricity
Ohm Analytics’ data platform for solar, storage, and broader electrification aggregates a proprietary database of projects in the U.S. based on thousands of sources.
Manufacturing
Advanced Ionics’s electrolyzers use up to 50% less electricity per kilogram of hydrogen and work in an intermediate temperature range—above liquid water but below expensive, superheated steam. The startup was previously a Greentown Go Energize 2022 participant.
Caravel Bio is developing a novel synthetic-biology platform that uses microbial spores and enzymes to create catalysts that are long-lasting and can withstand extreme conditions and environments. It’s participating in Greentown Go Make 2023.
Circularise develops a blockchain platform that provides digital product passports for end-to-end traceability and secure data exchange for industrial supply chains. Circularise is returning to Greentown as part of Go Make 2023, the startup’s third Greentown Go program.
Corumat, a Go Make 2023 participant back for its second Go program, converts organic waste into high-performance, insulating, greaseproof, and biodegradable packaging materials.
FluxWorks’ non-contact, lubrication-free, highly efficient magnetic gears can be used everywhere from outer space to under the sea.
Glimpse provides a scalable and collaborative solution to visualize battery scans and continuously monitor key battery-design features.
Hertha Metals is developing technology to cost-effectively produce steel from low-grade iron ores with 98% lower CO2 emissions than the conventional process.
Maple Materials develops a low-cost electrolysis process to split carbon dioxide into graphite and oxygen. The startup is part of the Go Make 2023 cohort.
Universal Matter, a Go Make 2023 participant, develops a proprietary Flash Joule Heating process that converts carbon waste into high-value and high-performance graphene materials to efficiently create sustainable circular economies.
Verde Technologies is building the next generation of lightweight, flexible solar panels for mass industrial and commercial adoption using a mineral called perovskite, an abundant and high-performing solar material.
