13 CleanTech Companies to Watch Right Now (2022)
Electric vehicles are no longer a distant aspiration. Sustainable infrastructure has made its way to the top of the government policy priorities list. The International Panel on Climate Change AR6 report nudged climate conversations further into the mainstream, and COP26 illuminated ideas about what must be done to solve the climate crisis. Yes, the pandemic was and remains a challenge. But out of the discomfort, innovation has continued, and public and corporate awareness is shifting to support a clean new world.
It’s an exciting time to be a cleantech company. It’s also an exciting time to be a cleantech spectator. Here are 13 cleantech companies that are making headlines with their groundbreaking green solutions.
Up to 30% of solar and wind farm capacity is wasted, and Soluna Computing has set out to save every megawatt. Soluna is working to achieve this by buying up what would be lost energy and using it to power small-footprint data centers that focus on batchable processes such as cryptocurrency mining and machine learning. This is a boon to not only the climate but to asset owners who gain revenue by selling their power plant’s excess energy.
Soluna’s sustainable computing approach is especially timely for cryptocurrency mining, which has come under scrutiny for its environmental impacts. As the company makes its green solution the standard for renewable power plants, which it expects to do over the next three years, it will inevitably reduce the negative climate effects of multiple industries.

Insects probably don’t come to mind when you think of technology, but Chapul Farms is proving they can be with their modular insect farms that close agricultural production loops. The farms house black soldier fly larvae (BSFL) and can be built on-site where organics waste streams need to be managed, eliminating carbon emissions from relocating the waste. BSFL can consume feedstocks other waste-to-value technologies can’t, such as wet organics waste. Their excrement can then be used to amend soil with nutrients, and the insects themselves are a superior feed for fish and some animals.

Traditional solar has its advantages, but it also has its downsides, like taking up valuable space and not being aesthetically pleasing. Ubiquitous Energy eliminates these disadvantages with their UE Power™ technology, a photovoltaic window coating, which uses solar energy from glass surfaces to generate power. The company has also solved the low production issue associated with the transparent solar cells their technology uses, achieving a world record of up to 10% efficiency.
Ubiquitous Energy successfully closed a $30 million series B funding round in 2022. The company is now seeking a location for its first high-volume manufacturing line and plans to continue research and development to integrate UE Power™ technology into the window industry.

SimpliPhi Power built better, safer batteries without cobalt, which is toxic and has a problematic supply chain with ties to child labor. Then they used those batteries to create scalable energy storage systems for residential, commercial, and portable applications. Their batteries have longer lifespans, too.
Their innovation did not go unnoticed. In 2021, SimpliPhi was acquired by power equipment manufacturer Briggs & Stratton. Their products will continue to be available through SimpliPhi while extending availability through the new owner.
“This acquisition quickly establishes a strong position for Briggs & Stratton in the high-growth energy storage system market,” says Steve Andrews, President and CEO of Briggs & Stratton in a press release. “The SimpliPhi Power team brings deep application expertise, strong technical support and proven, successful products to the Briggs & Stratton portfolio of power-agnostic products and technology solutions.”

Have you heard of chitosan? You have now, and you won’t forget it after hearing the story of how Craig Kasberg saw a mountain of crab shells as potential for a sustainability startup.
Kasberg may not have had a science background, but he knew the fishing industry well—including waste streams. Today Tidal Vision helps divert the billions of pounds of crustacean shells that go to waste annually and transforms them into chitosan.
Historically, chitosan was made in China with a process that produced Toxic waste. Tidal Vision is the leading domestic producer of Chitosan, and they use a safer “green chemistry” process.
Chitosan has several uses across verticals including textiles, agriculture, water treatment, and food preservation.

30% of crop production goes to feed livestock. Feed makes up 50% of the cost of meat. Beta Hatch sees these problems as an opportunity to industrialize insect agriculture, and they’re well on their way. Beta Hatch recently announced they raised $10 million in a funding round led by Lewis & Clark AgriFood.
The Beta Hatch approach to “insect entrepreneurship” goes beyond raising mealworms. Their facility in Cashmere, WA is powered by renewable energy sources, and the mealworms provide a waste-to-value service. “We believe co-locating with waste sources of all types makes for not just more sustainable production, but also lower costs and shorter transportation distances,” CEO Virginia Emery told GeekWire.
