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.

Sage Geosystems taps Halliburton to advance Nevada geothermal project

power partnership

Houston-based Sage Geosystems has selected oil and gas powerhouse Halliburton to provide cementing and stimulation services at its enhanced geothermal project in Nevada known as Project Vector.

“Our technology and experience will support Sage as it advances its geopressured geothermal technology,” Shawn Skobel, vice president at Halliburton, said in a news release.

Halliburton will provide Sage with technical modeling, engineering design, and field execution support as part of its specialized cementing and stimulation services at Project Vector at Ormat Technologies' Blue Mountain geothermal power plant. Sage announced the location of the geothermal project in September.

At the time, Sage said it expected to begin drilling the first well at Project Vector this year, with the first electricity to be generated in 2027 and full-scale production to start in 2028.

The project will use Sage’s enhanced geothermal systems (EGS) method in a two-well system to convert geothermal heat into electricity. The project aims to help meet industrial and residential demand, especially as data centers strain energy grids.

Founded in 2020, Sage has raised $159 million across three funding rounds. Its technology aims to reach Earth’s natural heat source deep underground for more consistent power generation and utilizes engineered subsurface reservoirs to minimize water and energy losses and increase net power output. Through the process, Sage says it can enable reliable, 24/7 power generation.

“One of the keys to scaling next-generation geothermal is combining innovative subsurface technology with the proven capabilities and execution of the oil and gas industry,” Jason Peart, Chief Operating Officer of Sage Geosystems, added in the news release. “Halliburton brings decades of experience in well integrity and reservoir stimulation, two critical components of our development approach. By selecting an established industry leader, we are strengthening our ability to execute Project Vector and demonstrate that Sage’s technology can be replicated and deployed commercially across a broad range of geologies.”

Sage is building off prior success of its South Texas SMECI facility, which began operations in August. Project Vector supports Sage’s growing commercial pipeline, which includes a 150-megawatt geothermal power agreement with Meta.

New study shows Houston is still feeling effects of 2014-16 oil crash

lasting impact

A new study from Rice’s Kinder Institute shows that Houston is still feeling the economic effects of the 2014-2016 oil crash, more than a decade later.

Though Houston, nicknamed the Energy Capital of the World, has continued to grow over the time period, the city has still fallen behind other comparable metropolitan areas in earnings and job creation, according to the research. The report is one part of a three-part series that will take a look at regional economic mobility and suggest ideas to expand opportunity.

“When you look at what’s happened in other locations, we’re losing ground,” Flávio Cunha, director of the Center for Economic Mobility at Rice’s Kinder Institute for Urban Research, said in a release. “Our economy is growing, but it’s no longer growing at the rate it used to.”

Global oil prices fell 70 percent between 2014 and 2016, the report said, marking one of the three largest declines since World War II and the longest-lasting downturn since 1986. The report excluded pandemic-related gaps, and it mentions 2017’s Hurricane Harvey as a possible indicator that economic growth stalled after the 2014-2016 oil price crash recovery.

To understand the long-term impact of the crash, researchers compared Houston’s economic performance with 54 metropolitan areas like San Antonio, Pittsburgh and others with less dependence on the energy industry.

Some of the key findings in the report included:

  • Job creation: In 2019, Houston had approximately 240,000 fewer private-sector jobs than similar cities. Employment was 15 percent lower in goods-producing industries and 4 percent lower in the services industries than the control group.
  • Income shifts: Income per resident was 13 percent lower compared to the peer group. Workers who remained employed earned 10 percent less between 2015 and 2019 than in other metros. The 13 percent drop in income equates to roughly $76 billion a year in forgone income, or $10,700 per resident per year in 2025 dollars. The decline was a trend across every age group, education level and sex.
  • Population changes: The rate of people moving to Houston slowed, rather than a surge of people leaving.
  • Hiring changes: Hiring fell sharply for young workers ages 19-24.

Cunha says the most surprising finding was that these trends persisted a decade later. According to the report, by 2024, Houston’s wages and income per resident remained about a fifth and a sixth below those in peer cities, and jobs per resident had continued to lose ground.

“What really surprises me is not that there was this change. It’s that this change has been long-lasting,” he added. “We followed it up to 2024, and we still don’t detect that the economy has recovered from that one shock.”

Read more about these businesses, their founders and their breakthrough technologies below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Erock

Energy infrastructure company Erock, previously known as Enchanted Rock, develops dual-purpose microgrids that rely on natural gas and renewable natural gas to produce lower carbon emissions and air pollutants than diesel generators. Its products can provide bridge power before grid interconnection, backup power during outages and dispatchable capacity that supports long-term grid reliability. The company has more than 1,100 megawatts of installed capacity and over 20 years of experience serving commercial, municipal and large-scale technology customers.

Erock completed its initial public offering this year, raising approximately $600 million in gross proceeds. It also grew its contracted power system sales backlog to approximately $1.7 billion, up tenfold year-over-year, with production sold out through 2028, according to the company's application. The company secured a major equipment order from Anthropic, began construction of the 366-megawatt El Paso Electric project supporting Meta's data center campus, and started assembly operations at its Hyperion facility in Cypress, Texas.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A last month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Venus Aerospace

Spacetech company Venus Aerospace is developing a high-thrust rotating detonation rocket engine (RDRE) that replaces the subsonic combustion used in conventional rocket engines. The RDRE is a compact, simpler engine that can deliver up to 15 percent greater efficiency for defense and space applications. It completed its first U.S. flight test of the engine last summer.

Venus Aerospace was founded in 2020 by CEO Cassie Duggleby and CTO Andrew Duggleby. It raised a $20 million Series A in 2022 and $42 million Series A2 in 2025. It closed a $91 million Series B earlier this year and expanded its leadership team. The company is working toward longer-duration and higher-thrust testing and advancing its flight program.
