Houston-based Advantek Waste Management Services, which specializes in deep-injection wells that minimize the impact of land, air, and water waste, has launched a carbon removal and storage company.

The spinoff, Vaulted Deep, is getting off the ground with $8 million in seed funding.

Vaulted diverts sludgy organic waste, such as agricultural and livestock waste, before it’s dumped in a landfill or waterway or simply left on land to decompose. It then captures and stores carbon emissions generated by the organic waste.

A study published earlier this year by Louisiana State University ecologist Brian Snyder estimated that organic waste generates five gigatons of carbon dioxide per year. A gigaton equals one billion metric tons.

Vaulted is already off to an impressive start. For one thing, the startup has raised an $8 million seed round led by New York City-based carbon removal fund Lowercarbon Capital. Other investors include Advantek and San Francisco-based climatech VC fund Earthshot Ventures.

In addition, Vaulted has already nailed down purchase commitments from Frontier, a marketplace for buyers and sellers of carbon removal credits. Ryan Orbuch, a partner at Lowercarbon, is one of Frontier’s strategic advisers.

“Vaulted is literally cleaning up the planet, scaling field-proven injection terminology to safely dispose of harmful wastes like biosolids while permanently storing away millions of tons of CO2,” Orbuch says in a Vaulted news release.

While injection sequestration sites often take years to gain permits and start operating, Vaulted already boasts two permitted sites that are up and running. Vaulted offers carbon removal for $300 per ton, compared with more than $500 per ton charged by some competitors.

Advantek founder Omar Abou-Sayed is switching from CEO to chairman of Advantek, which launched in 1999, and will serve as executive chairman of Vaulted. Julia Reichelstein, a former investor at San Francisco-based climatech VC fund Piva Capital, has been tapped as CEO of Vaulted.

“Unlike many carbon removal technologies still in R&D, Vaulted’s technology and sites can safely and permanently store carbon underground, at scale, today,” says Abou-Sayed. “The early removals we will deliver are pivotal to keeping the window open to hold our planet’s warming below 1.5 degrees Celsius.”

Sunnova assets officially sold as founder launches new Houston energy startup

solar shift

Solaris Assets has completed its acquisition of the majority of Sunnova Energy International’s residential solar assets. Houston-based Sunnova filed for Chapter 11 bankruptcy this summer after piling up billions of dollars in debt.

Meanwhile, Sunnova founder and former CEO John Berger has launched a Houston-based home energy services startup, Otovo USA, which just received more than $4 million in seed funding.

Solaris now owns Sunnova’s residential solar services platform and its solar generation and storage portfolio, along with leases, loans and power purchase agreements. Sunnova’s operations are being shifted to SunStrong Management, an Austin-based asset manager for the renewable energy sector.

“By bringing together SunStrong’s asset management expertise with Sunnova’s nationally scaled customer base, we are creating a stronger, more capable leader in the solar industry,” Brendon Merkley, CEO of SunStrong, said in a news release. “Our priority is to maintain the highest levels of service for customers as we expand our footprint as a premier solar asset servicer.”

In June, Sunnova sold its new-home business to homebuilder Lennar for $15.2 million and sold certain assets to investment firm Atlas SP Partners for $15 million.

As of December, Sunnova’s debt totaled nearly $10.7 billion, Reuters reported. Sunnova faced numerous challenges in its quest to survive, including higher interest rates, the reduction of solar incentives in California, and a shakeup in federal subsidies for renewable energy.

Sunnova filed for Chapter 11 bankruptcy in June. A month later, a bankruptcy judge approved the court-supervised sale of Sunnova. Solaris’ acquisition of Sunnova closed Sept. 3.

As SunStrong absorbs the bulk of Sunnova’s assets, Berger — who quit in March as Sunnova’s CEO — has formed a new business. He’s now the founder and CEO of Otovo USA, a partner of European residential power company Otovo.

Otovo USA offers solar power systems, solar batteries, standby generators, EV chargers, electric-load managers, and other power generation and management systems. Otovo’s AI-supported offerings are now available in Texas; the company plans to expand nationwide.

Otovo USA raised its seed funding from the EIC Rose Rock Venture Fund, which invests in energy startups.

“Otovo USA is here to help the millions of Americans with home energy services that are fed up with the complexities of warranties, juggling multiple vendors, and long repair times,” Berger said. The startup, he added, “is bringing customers what they really need: reliable power and a single partner accountable for keeping it up and running. It’s your power, backed by ours.”

Houston robotics company unveils extreme-temperature tank robot

hot new robot

Houston- and Boston-based Square Robot Inc.'s newest tank inspection robot is commercially available and certified to operate at extreme temperatures.

The new robot, known as the SR-3HT, can operate from 14°F to 131°F, representing a broader temperature range than previous models in the company's portfolio. According to the company, its previous temperature range reached 32°F to 104°F.

The new robot has received the NEC/CEC Class I Division 2 (C1D2) certification from FM Approvals, allowing it to operate safely in hazardous locations and to perform on-stream inspections of aboveground storage tanks containing products stored at elevated temperatures.

“Our engineering team developed the SR-3HT in response to significant client demand in both the U.S. and international markets. We frequently encounter higher temperatures due to both elevated process temperatures and high ambient temperatures, especially in the hotter regions of the world, such as the Middle East," David Lamont, CEO of Square Robot, said in a news release. "The SR-3HT employs both active and passive cooling technology, greatly expanding our operating envelope. A great job done (again) by our engineers delivering world-leading technology in record time.”

The company's SR-3 submersible robot and Side Launcher received certifications earlier this year. They became commercially available in 2023, after completing initial milestone testing in partnership with ExxonMobil, according to Square Robot.

The company closed a $13 million series B round in December, which it said it would put toward international expansion in Europe and the Middle East.

Square Robot launched its Houston office in 2019. Its autonomous, submersible robots are used for storage tank inspections and eliminate the need for humans to enter dangerous and toxic environments.

Houston oil giant ConocoPhillips will lay off up to 25% of workforce

Workforce News

Oil giant ConocoPhillips is planning to lay off up to a quarter of its workforce, amounting to thousands of jobs, as part of broader efforts from the company to cut costs.

A spokesperson for ConocoPhillips confirmed the layoffs on Wednesday, September 3, noting that 20% to 25% of the company's employees and contractors would be impacted worldwide. ConocoPhillips currently has a global headcount of about 13,000 — meaning that the cuts would impact between 2,600 and 3,250 workers.

“We are always looking at how we can be more efficient with the resources we have,” a ConocoPhillips' spokesperson said via email, adding that the company expects the “majority of these reductions” to take place before the end of 2025.

ConocoPhillips' shares fell 4.3% last week. The Houston-based company's stock now sits at under $95 per share, down nearly 14% from a year ago.

News of the coming layoffs was first reported by Reuters, with anonymous sources telling the outlet that CEO Ryan Lance detailed the plans in a video message earlier Wednesday. In that video, Reuters reported, Lance said the company needed “fewer roles” while he cited rising costs.

Last month, ConocoPhillips reported second-quarter earnings of $1.97 billion. That beat Wall Street expectations, but was down from the nearly $2.33 billion the company reported for the same period last year.

In its latest earnings, reported on August 7, ConocoPhillips continued to point to cost cutting efforts — noting that it had identified more than $1 billion in cost reductions and margin optimization. The company also said it had agreed to sell its Anadarko Basin assets for $1.3 billion.
