California geothermal co. grows C-suite, grows presence in Houston

making moves

A geothermal company with its headquarters in Palo Alto, California, has named new members of its C-suite and, at the same time, has expanded its operational footprint in Houston.

XGS Energy promoted Axel-Pierre Bois to CTO and Lucy Darago to chief commercial officer. Darago is based in Austin, and Bois, from France, lists his role as based in Houston on LinkedIn. Both have worked at XGS since February of last year.

“Axel and Lucy’s proven operational excellence and technical knowledge has helped propel XGS forward as we enter our next phase of growth,” Josh Prueher, CEO of XGS Energy, says in a news release. “I’m thrilled to have them both join XGS’ C-suite and have their support as we continue to grow our team, further advance our next-generation geothermal technology, and invest in our multi-gigawatt project pipeline.”

The news coincides with XGS's recent lease of over 10,000 square feet of office space in Memorial City. The company reports it plans to continue growth in the Houston region, "leveraging the region’s leading engineering and operational workforce and intensifying energy transition activity," reads the statement.

Bois was promoted from senior vice president of technology and has over 30 years of experience in geomechanics, wellbore integrity, completions design, and cement and rock testing. He previously founded and served as CEO of CURISTEC, a technical advisory firm providing services in oil and gas, geothermal, and geologic storage industries.

“We have developed a unique and proprietary approach to boosting the heat-harvesting potential of geothermal wells that is ready for commercial deployment in a range of environments today. I am excited to continue to grow our incredible team of scientists and engineers working on this important technology,” Bois says in the release. “We’re at the beginning of what this technology can unlock when it comes to supplying reliable, clean, and affordable geothermal energy globally.”

In her previous role as vice president of strategy, Darago led XGS’s financing strategy, which included a $20 million Series A expansion announced earlier this year. As CCO, she will oversee XGS’ global project development and will maintain a leading role in corporate affairs.

“It’s an exciting time to bring XGS’ technology to market. Demand for carbon-free baseload energy is at a record high, and the XGS system’s ability to unlock geothermal in more places, in a predictable and bankable way, is tailor-made for this moment,” Darago adds. “I am honored by our team and Board’s trust and look forward to helping drive the next stage of growth for XGS.”

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 cleantech startup closes $17M round to tap into hot geothermal sector

fresh funding

Houston-area startup Hephae Energy Technology Corp. has closed a $17.8 million Series A financing round to commercialize its geothermal technology.

The round was co-led by Pennsylvania-based Susquehanna Sustainable Investments, which invests in early-stage climatech companies, and Copenhagen-based Underground Ventures, which focuses on geothermal energy startups. Alfa8, Baruch Future Ventures, Centaurus Capital LP, Elemental Impact, Exa Ventures, Future Ventures, Grantham Foundation for the Protection of the Environment, New System Ventures and True North Institute joined the round, along with existing Houston-based investor Nabors Industries. Hyphae reports in a news release that the Series A round brings the company's total capital raised to $24.7 million.

Hephae develops ultra-high-temperature downhole sensing, measurement, communications and control systems that can withstand the heat of geothermal sites, which are hotter and deeper than traditional oil and gas reservoirs. The company's Pandora210 system can operate at up to 400 degrees Fahrenheit.

Hephae reports that it plans to use the new funding to commercialize its Pandora210 tool and to launch research and development into systems that can withstand temperatures of up to 570 degrees Fahrenheit. Houston-based Fervo Energy, for instance, recently tapped its hottest geothermal well to date in western Utah, showing temperatures above 555 degrees Fahrenheit.

"Commercial deployment represents a major milestone in our mission to scalable, always-on, emission-free power globally, with a world-class team to tackle this problem," Steve Krase, CEO of Hephae Energy Technology, said in the release." This investment enables Hephae to transition from development to scale, delivering the ultra-high temperature drilling technologies needed to support the rapid growth of the geothermal industry in the US and international markets."

Hephae has been collaborating with Fervo Energy in the field. The company told the Houston Business JournalHouston Business Journal this spring that it expected its Pandora210 technology to be deployed at its Utah sites.

“Fervo is encouraged by the early progress of our collaboration with Hephae, whose novel high-temperature innovations have the potential to contribute positively to EGS economics, unlock higher-energy geothermal resources, and further cement the competitiveness of next-generation geothermal power," Elliot Howard, director of drilling and completions at Fervo, added in the release.

As the geothermal industry continues to scale, Hephae says it aims for its technology to help companies "unlock hotter, deeper resources that result in lower produced energy costs."

The Spring-based startup was founded in 2020 by CEO Steve Krase and CTO John Clegg. Krase previously launched Navigate Energy Services, which was acquired by Nabors in 2013. Clegg is also an industry veteran and has held numerous leadership positions at energy companies, including Weatherford, NOV, Schlumberger and others.
