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-based Nauticus Robotics has a new CEO and fresh funding. Photo via LinkedIn

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.

Houston team’s discovery brings solid-state batteries closer to EV use

a better battery

A team of researchers from the University of Houston, Rice University and Brown University has uncovered new findings that could extend battery life and potentially change the electric vehicle landscape.

The team, led by Yan Yao, the Hugh Roy and Lillie Cranz Cullen Distinguished Professor of Electrical and Computer Engineering at UH, recently published its findings in the journal Nature Communications.

The work deployed a powerful, high-resolution imaging technique known as operando scanning electron microscopy to better understand why solid-state batteries break down and what could be done to slow the process.

“This research solves a long-standing mystery about why solid-state batteries sometimes fail,” Yao, corresponding author of the study, said in a news release. “This discovery allows solid-state batteries to operate under lower pressure, which can reduce the need for bulky external casing and improve overall safety.”

A solid-state battery replaces liquid electrolytes found in conventional lithium-ion cells with a solid separator, according to Car and Driver. They also boast faster recharging capabilities, better safety and higher energy density.

However, when it comes to EVs, solid-state batteries are not ideal since they require high external stack pressure to stay intact while operating.

Yao’s team learned that tiny empty spaces, or voids, form within the solid-state batteries and merge into a large gap, which causes them to fail. The team found that adding small amounts of alloying elements, like magnesium, can help close the voids and help the battery continue to function. The team captured it in real-time with high-resolution videos that showed what happens inside a battery while it’s working under a scanning electron microscope.

“By carefully adjusting the battery’s chemistry, we can significantly lower the pressure needed to keep it stable,” Lihong Zhao, the first author of this work, a former postdoctoral researcher in Yao’s lab and now an assistant professor of electrical and computer engineering at UH, said in the release. “This breakthrough brings solid-state batteries much closer to being ready for real-world EV applications.”

The team says it plans to build on the alloy concept and explore other metals that could improve battery performance in the future.

“It’s about making future energy storage more reliable for everyone,” Zhao added.

The research was supported by the U.S. Department of Energy’s Battery 500 Consortium under the Vehicle Technologies Program. Other contributors were Min Feng from Brown; Chaoshan Wu, Liqun Guo, Zhaoyang Chen, Samprash Risal and Zheng Fan from UH; and Qing Ai and Jun Lou from Rice.

Texas drivers continue to pump the brakes on EVs, shows new report

EV adoption

Even though Texas is home to Tesla, a major manufacturer of electric vehicles, motorists in the Lone Star State aren’t in the fast lane when it comes to getting behind the wheel of an EV.

U.S. Department of Energy data compiled by Visual Capitalist shows Texas has 689.9 EV registrations per 100,000 people, putting it in 20th place for EV adoption among the 50 states and the District of Columbia. A report released in 2023 by the University of Houston and Texas Southern University found that a little over 5 percent of Texans drove EVs.

California leads all states for EV adoption, with 3,025.6 registrations per 100,000 people, according to Visual Capitalist. In second place is Washington, with an EV adoption rate of 1,805.4 per 100,000.

A recent survey by AAA revealed lingering reluctance among Americans to drive all-electric vehicles.

In the survey, just 16 percent of U.S. adults reported being “very likely” or “likely” to buy an all-electric vehicle as their next car. That’s the lowest level of interest in EVs recorded by AAA since 1999. The share of consumers indicating they’d be “very unlikely” or “unlikely” to buy an EV rose to 63 percent, the highest level since 2022.

Factors cited by EV critics included:

  • High cost to repair batteries (62 percent).
  • High purchase price (59 percent).
  • Ineffective transportation for long-distance travel (57 percent).
  • Lack of convenient public charging stations (56 percent).
  • Fear of battery running out of power while driving (55 percent).

“Since AAA began tracking consumer interest in fully electric vehicles, we’ve observed fluctuations in enthusiasm,” said Doug Shupe, corporate communications manager for AAA Texas. “While automakers continue investing in electrification and expanding EV offerings, many drivers still express hesitation — often tied to concerns about cost, range, and charging infrastructure.”

18 Houston-based energy companies land on Forbes Global 2000 list
