Corporate sustainability initiatives may open doors for carbon offset startups

Commitments to carbon neutrality keep coming from all corners of the business world — over the past few weeks, companies ranging from the fast-casual restaurant chain Sweetgreen to the security-focused networking IT company Palo Alto Networks to the online craft retailer Etsy committed to net-zero carbon emission plans.

As the companies look for ways to reduce their energy consumption, they’re turning to carbon offset programs as a stopgap measure until the energy grid decarbonizes, they implement technologies to reduce their energy consumption, or both.

This push toward corporate sustainability is creating all kinds of strange bedfellows and startup opportunities, with major corporate offset programs and the establishment of new startups focused on offsets creating channels for sustainable technologies to get to market.

The latest example of a company leveraging a sustainability angle to tie a corporate partner even closer to their business is the agreement between Delta and Deloitte, which involves the accounting and consulting firm paying Delta for renewable jet fuel to offset the emissions of its corporate travel.

To be clear, a better policy for Deloitte would be to cut back on non-essential travel significantly and focus on doing as much remote work as possible to reduce the need for flights. But in some cases business travel is unavoidable, and most folks want to get back to a pre-pandemic normal, which — at least in the U.S. and other countries — will include significantly ramping up air travel for a percentage of the population.

As the BBC noted, air travel accounts for roughly 5 percent of the emissions that contribute to global climate change, but only a small percentage of the world actually uses air transport. According to one analysis from the International Council on Clean Transport, just 3 percent of the world’s population flies regularly. And if everyone in the world did fly, aircraft emissions would top the CO2 emissions of the entire U.S.

Which brings us back to Deloitte and Delta and startups.

Delta’s deal to buy sustainable aviation fuel that would offset a portion of the carbon emissions associated with Deloitte’s business travel is one small step toward greening the airline industry, but the question is whether it’s a significant first step or just an attempt to greenwash the unsustainable travel habits of a consulting industry that prides itself on such perks.

Geothermal startups get another boost from Chevron as the oil giant backs a geothermal project developer

The U.S.-based oil major Chevron is doubling down on its investment in geothermal power by investing in a Swedish developer of low-temperature geothermal and heat power projects called Baseload Capital.

Oil companies are under pressure to find new lines of business as the world prepares for a massive shift to renewable energy resources to power all aspects of industry in the face of mounting climate-related disasters caused by greenhouse gas emissions warming the temperature on the planet.

Joining Chevron in the investment was the ubiquitous billionaire-backed clean energy investment firm Breakthrough Energy Ventures and a Swedish investment group called Gullspang Invest AB.

The investment into Baseload follows closely on the heels of another commitment that Chevron made to the geothermal technology developer Eavor and a recent Breakthrough Energy Ventures investment in the Google-affiliated company, Dandelion Energy (a spinout from Google’s parent company’s moonshot technology development business unit, called X).

Dandelion and Eavor are just two examples of a groundswell of startups working to leverage the knowledge from the oil and gas industry to tap geothermal resources for applications ranging from baseload energy to home heating and cooling.

They’re joined by businesses like Fervo EnergyGreenFire Energy and Sage Geosystems, who’re all leveraging heat to generate power.

As Chevron noted in its press release, heat power is an affordable form of renewable energy that can be harnessed from either geothermal resources or waste heat.

The investments in Baseload and Eavor are financed by CTV’s Core Venture fund, which identifies companies with technology that can add efficiencies to Chevron’s core business in operational enhancement, digitalization and lower-carbon operations, the company said in a statement.

Together the two businesses are planning pilot projects to test technology and could look to current Baseload operations in Japan, Taiwan, Iceland or the United States to develop projects.

Financial terms of the deal were undisclosed. 

“In August, we announced that we were looking for a new strategic investor to help us accelerate deployment in our key markets,” said Baseload’s Chief Executive Officer Alexander Helling. “We couldn’t have asked for a better one. Chevron complements our group of owners and adds expertise in drilling, engineering, exploration and more. These assets are expected to accelerate our ability to deploy heat power and strengthen our way of working.”

Noya Labs turns cooling towers into direct air capture devices for CO2 emissions

Not every company’s founders find themselves on a first-name basis with the local bomb squad, but then again not every company is Noya Labs, which wants to turn the roughly 2 million cooling towers at industrial sites and buildings across the U.S. into CO2-sucking weapons in the fight against global climate change.

When the company first started developing prototypes of its devices that attach to water coolers, the company’s founders, Josh Santos and Daniel Cavero, did what all good founders do, they started building in their backyard.

The sight of a 55-gallon oil drum and a yellow refrigeration tank in a sous vide bath attached to red and blue cables didn’t sit so well with the neighbors, so Santos and Cavero found themselves playing host to the bomb squad multiple times, according to the company’s chief executive, Santos.

“We proved that it could capture CO2, and we achieved something that no startup should achieve,” Santos said of the dubious bomb squad distinction.

Santos and Cavero were inspired to begin their experiments with direct air capture by an article describing some research into plants’ declining ability to capture carbon dioxide that Santos read on Caltrain on his way to work back in 2019. That article spurred the would-be entrepreneur and his roommate to get to work on experimenting with carbon chemistry.

Their first product was a consumer air purifier that would pull carbon dioxide from the atmosphere in homes and capture it. Homeowners could then sell the captured gases to Santos and Cavero who would then resell it. But the two quickly realized that the business model wasn’t economical, and went back to the drawing board.

They found their eventual application in industrial cooling towers, which the company’s tech can turn into CO2-capturing devices that have the capacity to take in between half a ton and a ton of carbon dioxide per day.

Noya’s tech works by adding a blend of CO2-absorbing chemicals to the water in the cooling towers. They then add an attachment to the cooling tower that activates what Santos called a regeneration process to convert the captured CO2 back into gas. Once they have captured the CO2 the company will look to resell it to industrial CO2 consumers.

It’s not green yet, at least not exactly, because that CO2 is being recirculated instead of sequestered, but Santos said it’s greener than existing sources of the gas, which come from ammonia and ethanol plants.

Five years from now we fully intend to have vertically integrated carbon capture and sequestration. Our first step is locally produced low-cost atmospherically captured CO2,” said Santos. “If we were to go all-in on a carbon capture, that would require a lot of time for us to develop. What this initial model allows us to do is fine-tune our capture technology while building up long-term to go to market.”

Santos called it the “Tesla roadster approach” so that the company can build up capital and get revenue and prove one piece of it as an MVP so they can prove other steps of it down the line.

Noya Labs already is developing a pilot plant with the Alexandre Family Farm that should capture between the estimated half a ton and one-ton target.

To develop the initial pilot and build out its team, the company has managed to raise $1.2 million from the frontier tech investment firm Fifty Years, founded by Ela Madej and Seth Bannon, and Chris Sacca’s Lowercarbon Capital (whose mission statement to invest in companies that will buy time to “unf*ck the planet” might be one of the greatest). The company’s also in Y Combinator.

“One of the things that makes us excited about this technology is that in the U.S. alone there are 2 million cooling towers. Looking conservatively — if our initial pilot plant can capture 1 ton per day — we’re at right over half a gigaton of CO2 capture.”

And companies are already raising their hands to pick up the CO2 that Noya would sell on the market. There’s a growing collection of startups that are using CO2 to make products. These companies range from the slightly silly, like Aether Diamonds, which uses CO2 to make… diamonds; to companies like Dimensional Energy or Prometheus Fuels, which make synthetic fuels with CO2, or Opus12, which uses CO2 in its replacements for petrochemicals.

Prices for commercial CO2 range between $125 per ton to $5,000 per ton, according to Santos. And Noya would be producing at less than $100 per ton. Current Direct Air Capture companies sell their CO2 from somewhere between $600 to $700 per ton.

Stoya’s first installation could cost around $250,000, Santos said. For Bannon, that means the company passes his “Mr. Burns test.”

“We’ve been digging into the DAC space but haven’t liked the techno-economics we’ve seen. Previous approaches have had too much capex and opex and not enough revenue potential,” Bannon wrote in an email. “That’s what Noya has solved. By leveraging existing industrial equipment, their model is profitable. And better yet, they make their carbon capture partners money, allowing them to scale this up fast. This creates an opportunity to profitably remove 1 gigaton-plus a year.”

The carbon offset API developer Patch confirms a $4.5 million round led by Andreessen Horowitz

Patch, the carbon offset API developer, has raised $4.5 million in financing to build out its business selling customers a way to calculate their carbon footprint and identify and finance offset projects that capture the equivalent carbon dioxide emissions associated with that footprint. 

Confirming TechCrunch reporting, Andreessen Horowitz led the round, which also included previous investors VersionOne Ventures, MapleVC and Pale Blue Dot Ventures.

Patch’s application protocol interface works for both internal and customer-facing operations. The company’s code can integrate into the user experience on a company’s internal site to track things like business flights for employees, recommending and managing the purchase of carbon credits to offset employee travel.

The software allows companies to choose which projects they’d like to finance to support the removal of carbon dioxide from the atmosphere, with projects ranging from the tried and true reforestation and conservation projects to more high-tech early-stage technologies like direct air capture and sequestration projects, the company said. 

Patch founders Brennan Spellacy and Aaron Grunfeld, two former employees at the apartment rental service Sonder, stressed in an interview that the company’s offset work should not be viewed as an alternative to the decarbonization of businesses that use its service. Rather, they see Patch’s services as a complement to other work companies need to do to transition away from a reliance on fossil fuels in business operations.

Patch currently works with 11 carbon removal suppliers and has plans to onboard another 10 before the end of the first quarter, the company said. These are companies like CarbonCure, which injects carbon dioxide into cement and fixes it so that it’s embedded in building materials for as long as a building lasts.

“Carbon removal credits can help to dramatically accelerate the deployment of technologies like CarbonCure’s, which are absolutely critical to helping us reach our global climate targets. Demand for high-quality, permanent credits is sky-rocketing, and listing credits on Patch will help us to attract a broader range of buyers,” said Jennifer Wagner, president of CarbonCure Technologies, in a statement. 

It also has around 15 customers already using its service, according to earlier TechCrunch reporting. Those buyers include companies like TripActions and the private equity firm EQT, which intends to extend the integration of Patch’s API from its own operations to those of its portfolio companies down the road, according to Spellacy.

Grunfeld said that the company would be spending the money to hire more staff and developing new products. From its current headcount of six employees, Patch intends to bring on another 24 by the end of the year.

As the company expands, it’s looking to some of the startups providing carbon emissions audit and verification services as a channel that the company’s API can integrate with and sell through. These would be businesses like CarbonChainPersefoni and another Y Combinator graduate, SINAI Technologies.

“An increasing number of businesses are taking leadership positions in an effort to reduce emissions to try to counteract global warming,” said Jeff Jordan, managing partner at Andreessen Horowitz. “Patch makes it much easier for companies to add carbon removal to their core business processes, aggregating verified carbon-removal supply and offering turn-key access to it to companies through an easy-to-implement API.”

ChargeLab raises seed capital to be the software provider powering EV charging infrastructure

As money floods into the electric vehicle market a number of small companies are trying to stake their claim as the go-to provider of charging infrastructure. These companies are developing proprietary ecosystems that work for their own equipment but don’t interoperate.

ChargeLab, which has raised $4.3 million in seed financing led by Construct Capital and Root Ventures, is looking to be the software provider providing the chargers built by everyone else.

“You’ll find everyone in every niche and corner,” says ChargeLab chief executive Zachary Lefevre. Lefevre likens Tesla to Apple with its closed ecosystem and compares ChargePoint and Blink, two other electric vehicle charging companies, to Blackberry — the once dominant smartphone maker. “What we’re trying to do is be Android,” Lefevre said.

That means being the software provider for manufacturers like ABB, Schneider Electric and Siemens. “These guys are hardware makers up and down the value stack,” Lefevre said.

ChargeLab already has an agreement with ABB to be their default software provider as they go to market. The big industrial manufacturer is getting ready to launch their next charging product in North America.

As companies like REEF and Metropolis revamp garages and parking lots to service the next generation of vehicles, ChargeLab’s chief executive thinks that his software can power their EV charging services as they begin to roll out that functionality across the lots they own.

Lefevre got to know the electric vehicle charging market first as a reseller of everyone else’s equipment, he said. The company had raised a pre-seed round of $1.1 million from investors including Urban.us and Notation Capital and has now added to that bank account with another capital infusion from Construct Capital, the new fund led by Dayna Grayson and Rachel Holt, and Root Ventures, Lefevre said.

Eventually the company wants to integrate with the back end of companies like ChargePoint and Electrify America to make the charging process as efficient for everyone, according to ChargeLab’s chief executive.

As more service providers get into the market, Lefevre sees the opportunity set for his business expanding exponentially. “Super open platforms are not going to be building an EV charging system any more than they would be building their own hardware,” he said.
