Greentown Labs names interim leader as hunt for CEO continues

at the helm

Greentown Labs, after announcing its CEO is stepping down at the end of the month, has named the climatetech incubator's interim leader.

Kevin Dutt, a recently named member of Greentown's board of directors based in the Boston area, has been appointed interim CEO. The decision, made by the board, is effective July 8. Dutt is a management consultant at Sustainable Edge Consulting, as well as an environmental entrepreneur, executive, and adviser with 25 years of experience.

"We continue to believe deeply in Greentown and are proud to have one of our board members step into this role before our next long-term CEO is identified," the nonprofit writes in the announcement. "We are confident Kevin is best suited to lead Greentown through this time of transition—his experience in climate and sustainability, philanthropy, and venture will play a key role in helping seamlessly guide Greentown in the coming months."

Dutt will lead the organization, which has dual locations in Houston and Somerville, Massachusetts, following outgoing CEO and President Kevin Knobloch. Knobloch announced in May that he will be stepping down after less than a year in the position. He was named CEO last September, previously serving as chief of staff of the United States Department of Energy in President Barack Obama’s second term.

The news of Knobloch's departure came just over a month after the organization announced that it was eliminating 30 percent of its staff, which affected 12 roles in Boston and six in Houston.

Dutt is the fourth person to take the help of Greentown since Emily Reichert, who held the position from 2013 to 2022, stepped down. Prior to Knobloch's appointment, Greentown's Co-Founder Jason Hanna and former CFO Kevin T. Taylor, who each served in an interim capacity.

Houston offshore robotics company secures $12M, makes major leadership changes

big moves

In the wake of a leadership reshuffling and amid lingering financial troubles, publicly traded Nauticus Robotics, a Webster-based developer of subsea robots and software, has netted more than $12 million in a second tranche of funding.

The more than $12 million in new funding includes a $9.5 million loan package.

Nauticus says the funding will accelerate certification of the company’s flagship Aquanaut robot, which is being prepared for its inaugural mission — inspecting a deep-water production facility in the Gulf of Mexico that’s owned by a major oil and gas company.

The new funding comes several weeks after the company announced a change in leadership, including a new interim CEO, interim chief financial officer, and lead general counsel.

Former Halliburton Energy Services executive John Gibson, the interim CEO, became president of Nauticus last October and subsequently joined the board. Gibson replaced Nauticus founder Nicolaus Radford in the CEO role. Radford’s LinkedIn profile indicates he left Nauticus in January 2024, the same month that Gibson stepped into the interim post.

Radford founded what was known as Houston Mechatronics in 2014.

Victoria Hay, the new interim CFO at Nauticus, and Nicholas Bigney, the new lead general counsel, came aboard in the fourth quarter of 2023.

“We currently have the intellectual property, prototypes, and the talent to deliver robust products and services,” Gibson says in a news release. “Team Nauticus is now laser-focused on converting our intellectual property, including both patents and trade secrets, into differentiated solutions that bring significant value to both commercial and government customers.”

A couple of weeks after the leadership shift, the NASDAQ stock market notified Nauticus that the average closing price of the company’s common stock had fallen below the $1-per-share threshold for 30 consecutive trading days. That threshold must be met to maintain a NASDAQ listing.

Nauticus was given 180 days to lift its average stock price above $1. If that threshold isn’t reached during that 180-day period, the company risks being delisted by NASDAQ. The stock closed February 6 at 32 cents per share.

The stock woes and leadership overhaul came on the heels of a dismal third-quarter 2023 financial report from Nauticus. The company’s fourth-quarter 2023 financial report hasn’t been filed yet.

For the first nine months of 2023, Nauticus reported an operating loss of nearly $20.9 million, up from almost $11.3 million during the same period a year earlier. Meanwhile, revenue sank from $8.2 million during the first nine months of 2022 to $5.5 million in the same period a year later.

Nauticus went public in September 2022 through a SPAC (special purpose acquisition company) merger with New York City-based CleanTech Acquisition Corp., a “blank check” company that went public in July 2021 through a $150 million IPO. The SPAC deal was valued at $560 million when it was announced in December 2021.

Nauticus recently hired investment bank Piper Sandler & Co. to help evaluate “strategic options to maximize shareholder value.”

One of the strategic alternatives involves closing Nauticus’ previously announced merger with Houston-based 3D at Depth, which specializes in subsea laser technology. When it was unveiled last October, the all-stock deal was valued at $34 million.

Meta to buy all power from new ENGIE Texas solar farm

power purchase

Meta, the parent company of social media platform Facebook, has agreed to buy all of the power from a $900 million solar farm being developed near Abilene by Houston-based energy company ENGIE North America.

The 600-megawatt Swenson Ranch solar farm, located in Stonewall County, will be the largest one ever built in the U.S. by ENGIE. The solar farm is expected to go online in 2027.

Meta will use electricity generated by the solar farm to power its U.S. data centers. All told, Meta has agreed to purchase more than 1.3 gigawatts of renewable energy from four ENGIE projects in Texas.

“This project marks an important step forward in the partnership between our two companies and their shared desire to promote a sustainable and competitive energy model,” Paulo Almirante, ENGIE’s senior executive vice president of renewable and flexible power, said in a news release.

In September, ENGIE North America said it would collaborate with Prometheus Hyperscale, a developer of sustainable liquid-cooled data centers, to build data centers at ENGIE-owned renewable energy and battery storage facilities along the I-35 corridor in Texas. The corridor includes Austin, Dallas-Fort Worth, San Antonio and Waco.

The first projects under the ENGIE-Prometheus umbrella are expected to go online in 2026.

ENGIE and Prometheus said their partnership “brings together ENGIE's deep expertise in renewables, batteries, and energy management and Prometheus' highly efficient liquid-cooled data center design to meet the growing demand for reliable, sustainable compute capacity — particularly for AI and other high-performance workloads.”

Fervo named to prestigious list of climate tech companies to watch

top honor

Houston-based Fervo Energy has received yet another accolade—MIT Technology Review named the geothermal energy startup to its 2025 list of the 10 global climatetech companies to watch.

Fervo, making its second appearance on the third annual list, harnesses heat from deep below the ground to generate clean geothermal energy, MIT Technology Review noted. Fervo is one of four U.S. companies to land on the list.

Fervo “uses fracking techniques to create geothermal reservoirs capable of delivering enough electricity to power massive data centers and hundreds of thousands of homes,” MIT Technology Review said.

MIT Technology Review said it produces the annual list to draw attention to promising climatetech companies that are working to decarbonize major sectors of the economy.

“Though the political and funding landscape has shifted dramatically in the US since the last time we put out this list,” MIT Technology Review added, “nothing has altered the urgency of the climate dangers the world now faces — we need to rapidly curb greenhouse gas emissions to avoid the most catastrophic impacts of climate change.”

In addition to MIT Technology Review’s companies-to-watch list, Fervo has appeared on similar lists published by Inc.com, Time magazine and Climate Insider.

In an essay accompanying MIT Technology Review’s list, Microsoft billionaire Bill Gates said his Breakthrough Energy Ventures investment group has invested in more than 150 companies, including Fervo and another company on the MIT Technology Review list, Redwood Materials.

In his essay, Gates wrote that ingenuity is the best weapon against climate change.

Yet climate technology innovations “offer more than just a public good,” he said. “They will remake virtually every aspect of the world’s economy in the coming years, transforming energy markets, manufacturing, transportation, and many types of industry and food production. Some of these efforts will require long-term commitments, but it’s important that we act now. And what’s more, it’s already clear where the opportunities lie.”

In a recent blog post highlighting Fervo, Gates predicted geothermal will eventually supply up to 20 percent of the world’s electricity, up from his previous estimate of as much as 5 percent.

Fervo is one of the pioneers in geothermal energy. Gates and other investors have pumped $982 million into Fervo since its founding in 2017. With an estimated valuation of $1.4 billion, Fervo has achieved unicorn status, meaning its valuation as a private company exceeds $1 billion.

Aside from Breakthrough Energy Ventures, oilfield services provider Liberty Energy is a Fervo investor. U.S. Energy Secretary Chris Wright was chairman and CEO of Denver-based Liberty Energy before assuming his federal post.

Axios reported on Oct. 1 that Fervo is raising a $300 million series E round, which would drive up the startup’s valuation. News of the $300 million round comes as the company gears up for a possible IPO, according to Axios.

Fervo co-founder and CEO Tim Latimer told Axios this spring that a potential IPO is likely in 2026 or 2027. Ahead of an IPO, the startup is aiming for a $2 billion to $4 billion valuation, Axios reported.

The first phase of Fervo’s marquee Cape Station geothermal energy plant in Utah is scheduled to go online next year, with the second phase set to open in 2028. Once it’s completed, the plant will be capable of generating 500 megawatts of power. This summer, the startup said it secured $205.6 million in capital to finance construction of the plant.

Rice University team develops eco-friendly method to destroy 'forever chemicals' in water

clean water research

Rice University researchers have teamed up with South Korean scientists to develop the first eco-friendly technology that captures and destroys toxic “forever chemicals,” or PFAS, in water.

PFAS have been linked to immune system disruption, certain cancers, liver damage and reproductive disorders. They can be found in water, soil and air, as well as in products like Teflon pans, waterproof clothing and food packaging. They do not degrade easily and are difficult to remove.

Thus far, PFAS cleanup methods have relied on adsorption, in which molecules cling to materials like activated carbon or ion-exchange resins. But these methods tend to have limited capacity, low efficiency, slow performance and can create additional waste.

The Rice-led study, published in the journal Advanced Materials, centered on a layered double hydroxide (LDH) material made from copper and aluminum that could rapidly capture PFAS and be used to destroy the chemicals.

The study was led by Rice professor Youngkun Chung, a postdoctoral fellow under the mentorship of Michael S. Wong. It was conducted in collaboration with Seoktae Kang, professor at the Korea Advanced Institute of Science and Technology, and Keon-Ham Kim, professor at Pukyung National University, who first discovered the LDH material.

The team evaluated the LDH material in river water, tap water and wastewater. And, according to Rice, that material’s unique copper-aluminum layers and charge imbalances created an ideal binding environment to capture PFAS molecules.

“To my astonishment, this LDH compound captured PFAS more than 1,000 times better than other materials,” Chung, lead author of the study and now a fellow at Rice’s WaTER (Water Technologies, Entrepreneurship and Research) Institute and Sustainability Institute, said in a news release. “It also worked incredibly fast, removing large amounts of PFAS within minutes, about 100 times faster than commercial carbon filters.”

Next, Chung, along with Rice professors Pedro Alvarez and James Tour, worked to develop an eco-friendly, sustainable method of thermally decomposing the PFAS captured on the LDH material. They heated saturated material with calcium carbonate, which eliminated more than half of the trapped PFAS without releasing toxic by-products.

The team believes the study’s results could potentially have large-scale applications in industrial cleanups and municipal water treatments.

“We are excited by the potential of this one-of-a-kind LDH-based technology to transform how PFAS-contaminated water sources are treated in the near future,” Wong added in the news release. “It’s the result of an extraordinary international collaboration and the creativity of young researchers.”
