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.

Wind and solar supplied over a third of ERCOT power, report shows

power report

Since 2023, wind and solar power have been the fastest-growing sources of electricity for the Electric Reliability Council of Texas (ERCOT) and increasingly are meeting stepped-up demand, according to a new report from the U.S. Energy Information Administration (EIA).

The report says utility-scale solar generated 50 percent more electricity for ERCOT in the first nine months this year compared with the same period in 2024. Meanwhile, electricity generated by wind power rose 4 percent in the first nine months of this year versus the same period in 2024.

Together, wind and solar supplied 36 percent of ERCOT’s electricity in the first nine months of 2025.

Heavier reliance on wind and solar power comes amid greater demand for ERCOT electricity. In the first nine months of 2025, ERCOT recorded the fastest growth in electricity demand (5 percent) among U.S. power grids compared with the same period last year, according to the report.

“ERCOT’s electricity demand is forecast to grow faster than that of any other grid operator in the United States through at least 2026,” the report says.

EIA forecasts demand for ERCOT electricity will climb 14 percent in the first nine months of 2026 compared with the same period this year. This anticipated jump coincides with a number of large data centers and cryptocurrency mining facilities coming online next year.

The ERCOT grid covers about 90 percent of Texas’ electrical load.

Micro-nuclear reactor to launch next year at Texas A&M innovation campus

nuclear pilot

The Texas A&M University System and Last Energy plan to launch a micro-nuclear reactor pilot project next summer at the Texas A&M-RELLIS technology and innovation campus in Bryan.

Washington, D.C.-based Last Energy will build a 5-megawatt reactor that’s a scaled-down version of its 20-megawatt reactor. The micro-reactor initially will aim to demonstrate safety and stability, and test the ability to generate electricity for the grid.

The U.S. Department of Energy (DOE) fast-tracked the project under its New Reactor Pilot Program. The project will mark Last Energy’s first installation of a nuclear reactor in the U.S.

Private funds are paying for the project, which Robert Albritton, chairman of the Texas A&M system’s board of regents, said is “an example of what’s possible when we try to meet the needs of the state and tap into the latest technologies.”

Glenn Hegar, chancellor of the Texas A&M system, said the 5-megawatt reactor is the kind of project the system had in mind when it built the 2,400-acre Texas A&M-RELLIS campus.

The project is “bold, it’s forward-looking, and it brings together private innovation and public research to solve today’s energy challenges,” Hegar said.

As it gears up to build the reactor, Last Energy has secured a land lease at Texas A&M-RELLIS, obtained uranium fuel, and signed an agreement with DOE. Founder and CEO Bret Kugelmass said the project will usher in “the next atomic era.”

In February, John Sharp, chancellor of Texas A&M’s flagship campus, said the university had offered land at Texas A&M-RELLIS to four companies to build small modular nuclear reactors. Power generated by reactors at Texas A&M-RELLIS may someday be supplied to the Electric Reliability Council of Texas (ERCOT) grid.

Also in February, Last Energy announced plans to develop 30 micro-nuclear reactors at a 200-acre site about halfway between Lubbock and Fort Worth.

Rice University partners with Australian co. to boost mineral processing, battery innovation

critical mineral partnership

Rice University and Australian mineral exploration company Locksley Resources have joined together in a research partnership to accelerate the development of antimony processing in the U.S. Antimony is a critical mineral used for defense systems, electronics and battery storage.

Rice and Locksley will work together to develop scalable methods for extracting and utilizing antimony. Currently, the U.S. relies on imports for nearly all refined antimony, according to Rice.

Locksley will fund the research and provide antimony-rich feedstocks and rare earth elements from a project in the Mojave Desert. The research will explore less invasive hydrometallurgical techniques for antimony extraction and explore antimony-based materials for use in batteries and other energy storage applications.

“This strategic collaboration with Rice marks a pivotal step in executing Locksley’s U.S. strategy,” Nathan Lude, chairman of Locksley Resources, said in a news release. “By fast-tracking our research program, we are helping rebuild downstream capacity through materials innovation that the country urgently requires.”

Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Materials Science and Nanoengineering at Rice, is the principal investigator of the project.

“Developing scalable, domestic pathways for antimony processing is not only a scientific and engineering challenge but also a national strategic priority,” Ajayan said in the news release. “By combining Rice’s expertise in advanced materials with Locksley’s resources, we can address a critical supply chain gap and build collaborations that strengthen U.S. energy resilience.”

The Rice Advanced Materials Institute (RAMI) will play a major role in supporting the advancement of technology and energy-storage applications.

“This partnership aligns with our mission to lead in materials innovations that address national priorities,” Lane Martin, director of RAMI, said in a news release. “By working with Locksley, we are helping to build a robust domestic supply chain for critical materials and support the advancement of next-generation energy technologies.”
