Houston investors are betting on a New York-based carbon capture startup's technology.

CarbonQuest announced it received series A funding from Houston-based Riverbend Energy Group. The terms of the deal were not disclosed. Founded in 2019, the company created its Distributed Carbon Capture technology that captures CO2 from buildings and onsite power generation systems, then liquifies and transports it to local businesses that need carbon for their production processes.

“We are one of the few carbon capture companies with commercial products on the market today, and this investment will enable us to continue bringing distributed carbon capture to a wider swath of the market,” Shane Johnson, president and CEO of CarbonQuest, says in a news release. “We are also excited to attract new talent and expand our North American operations.”

The company's compact, modular carbon capture solution has already been deployed in several New York City buildings and reports that it is focused on natural gas emissions from distributed onsite power generation in 2024. The fresh funding will help CarbonQuest lower its cost for customers and address new market segments, including biogenic sources of CO2, utility infrastructure, and more, per the release.

Additionally, the company plans to advance development of its Carbon Management Software, a platform that provides real-time data and analytics for users. Riverbend's Joe Passanante and Eric Danziger will join CarbonQuest’s board of directors as a part of the deal.

“We are thrilled to partner with CarbonQuest, a company at the forefront of distributed carbon capture technology,” Passanante, managing director at Riverbend, says in the release. “This investment reflects our commitment to advancing solutions that play a critical role in decarbonization.

"CarbonQuest’s innovative approach not only addresses that need, but also offers scalable, economically viable solutions that can be deployed across a wide range of markets," he continues. "We are excited to collaborate with CarbonQuest’s experienced and talented team and believe this partnership will be a game changer in multiple markets, helping to unlock the full potential of distributed carbon capture and significantly contribute to global climate goals.”

Houston co. enters new carbon capture collaboration focused on biofuels industry

cleaning up

Carbon Clean, a carbon capture company whose North American headquarters is in Houston, has forged a deal with a contractor to build modular carbon capture containers for the agricultural sector.

The company, based in the United Kingdom, says its tentative partnership with Merrill, Wisconsin-based AGRA Industries should speed up adoption of Carbon Clean’s CaptureX technology in the biofuel industry.

Carbon Clean’s technology has been installed at 49 sites around the world. Eighty percent of the sites have prefabricated modular carbon-capture containers, reducing construction and installation time.

The partnership will enable customers to capture CO2 released during the biofuel fermentation stage, enabling the production of fuels with lower carbon-intensity ratings. This will improve the ability of biofuel producers to claim federal tax credits, Carbon Clean says.

“Carbon Clean’s collaboration with AGRA Industries is a win-win for biofuel producers. Customers will benefit from the expertise of a leading agricultural engineering specialist and our modularized, innovative carbon capture technology that is cost-effective and simple to install,” Aniruddha Sharma, chair and CEO of Carbon Clean, says in a news release.

Carbon Clean’s customers include companies in the cement, steel, refinery, and energy-to-waste sectors.

Among the investors in Carbon Clean, founded in 2019, are Chevron, Samsung Ventures, Saudi Aramco Energy Ventures, and WAVE Equity Partners. To date, the company has raised $260 million in funding, according to data platform Tracxn.

ExxonMobil extends European fuel cell pilot project

next step

The Esso fuel business of Spring-based ExxonMobil is forging ahead with a pilot project at its Dutch refinery in Rotterdam to test technology aimed at reducing carbon emissions and simultaneously generating electricity and hydrogen.

ExxonMobil and FuelCell announced the pilot project in 2023.

“The unique advantage of this technology is that it not only captures CO2 but also produces low-carbon power, heat, and hydrogen as co-products,” Geoff Richardson, senior vice president of ExxonMobil Low Carbon Solutions, said last year.

The Rotterdam facility, which opened in 1960, will be the first location in the world to test the technology. The technology eventually could be rolled out at additional ExxonMobil sites.

The European Union is among the funders of the pilot project. FuelCell is making carbonate fuel cells for the project at its manufacturing plant in Torrington, Connecticut.

The extended agreement enables FuelCell to incorporate elements of the jointly developed technology into carbon capture products currently being marketed to customers. ExxonMobil and FuelCell are working on formalizing an arrangement for selling the new technology.

“The technology, which captures carbon while simultaneously generating electricity and hydrogen, could improve the economics of carbon capture and could potentially lower the barrier to broader adoption of carbon capture in the marketplace,” according to a FuelCell news release.

FuelCell says its 10-year partnership with ExxonMobil has focused on developing technology that reduces carbon emissions from emission-intensive sectors while generating electricity and hydrogen in the process — “something that no other fuel cell technology or conventional absorption systems can do.”

Navigating the energy transition is a relay race, and the baton is in Houston, says this energy executive. Photo courtesy of SCS

O&G exec: Houston is where the future of energy is taking shape

Q&A

Earlier this month, a West Texas-based oilfield equipment provider announced that it was opening an office in the Ion Houston. It's all a part of the company's energy transition plan.

SCS Technologies, based in Big Spring, Texas, has a new strategy and innovation-focused office in the Ion, the company announced last week. The company, which provides CO2 capture measurement and methane vapor recovery equipment for the energy, industrial, and environmental sectors, also announced René Vandersalm as the new COO.

These are just the latest moves for the company as the world moves away from hydrocarbons and toward a greener future, CEO Cody Johnson tells EnergyCapital, explaining that he recognizes Houston has a role in the energy transition.

"This is a relay race – a race that has already started," he says. "Houston is the place where the baton will be handed off – it’s the place where the race is occurring. SCS Technologies is determined to be part of this solution dreamed of and planned in Houston and then executed in the Permian Basin, where we call home."

In an interview with EnergyCapital, Johnson weighs in on the new office and the future of his company.

EnergyCapital: How has SCS’s business evolved amid the energy transition?

Cody Johnson: SCS Technologies was founded to design and fabricate customized Lease Automated Custody Transfer units in the Permian Basin. These LACT units were used primarily to measure the quality and quantity of crude oil at all points of custody transfer. Essentially, SCS Technologies produced the premier "crude cash registers" for the Permian Basin.

As the oil and gas industry has adapted into the energy transition industry, our customers and the communities we operate in have a growing need for SCS Technologies to use our design and fabrication of measurement skids to measure the quality and quantity of CO₂ or to design and fabricate methane — and other vent gases — Vapor Recovery Units. SCS Technologies’ design and fabrication expertise in measurement skids, pump skids, and compression skids, coupled with our Permian Basin based training and fabrication campus, ideally positioned us to answer the call to fill the expertise and capacity gap.

EC: How are you preparing for the future of energy?

CJ: Society has been powered for the past 100 years or so by the management of hydrocarbon molecules. The essential tools for that have been and continue to be oil rigs, pipelines, and refineries in large part. This has given society many benefits but at a price to the environment that isn’t sustainable. Over the next 50 years, society will complete a transition away from managing hydrocarbon molecules and towards managing electrons. Those electrons are created by wind, solar, geothermal, or nuclear processes and travel down copper wires. Managing this transition that is already occurring and working together to do it in the near-term future of energy.

As we execute this transition over the next several decades from managing molecules to managing electrons to provide energy, molecule management companies must find ways to reach net zero emissions in their management practices. This means primarily capturing and managing methane vapors and capturing and sequestering CO₂. This is starting in 2023 in a meaningful way and needs to continue past 2030 and probably past 2050 to have any chance to meet the globally shared social goal to achieve net zero emissions by 2050 and stay below a maximum increase of 1.5 degrees C in global temperatures.

The clock is ticking, and we are behind. The largest molecule management infrastructure investment in history must happen for us to reach these goals. It's mission-critical as one of the three things we simply cannot fail at to achieve net zero by 2050. SCS Technologies is very focused on being an intentional part of the tremendous supply chain buildout to support the infrastructure buildout.

EC: How does the new office in the Ion support these plans?

CJ: SCS Technologies needs to collaborate with the brightest minds working on the energy transition challenges. To contribute meaningfully to the overall effort and to be the thought leader in the methane vapor recovery and CO₂ compression and measurement niche, we need to be at the heart of the energy transition collaboration community. That beating heart is the Ion in Houston.

EC: What role does your new COO, René Vandersalm, play in SCS evolving with the energy transition?

CJ: René is a proven executive in growing mission-critical design and fabrication capacity without sacrificing quality. René’s experience, capabilities, and global network will play a key role in our path forward.

EC: Based in West Texas, SCS has a growing presence in Houston. Why do you see Houston as a leader in the energy transition?

CJ: West Texas has an amazing group of oil and gas professionals and infrastructure. We are proud of that heritage and will always maintain our roots and foundation there. Houston has the only community of engineers, scientists, universities, companies, investors, and key professional service providers that can deliver on the buildout of the molecule management infrastructure required to buy the electron management infrastructure folks time to transition fully to green energy after 2050.

This is a relay race – a race that has already started. Houston is the place where the baton will be handed off – it’s the place where the race is occurring. SCS Technologies is determined to be part of this solution dreamed of and planned in Houston and then executed in the Permian Basin, where we call home.

Houston oil and gas producer expands into renewables, announces new Baytown facility

Renewables News

Houston American Energy Corp. (NYSE: HUSA), an oil and gas exploration and production company, has entered into a definitive agreement to acquire New York-based Abundia Global Impact Group LLC, which specializes in converting waste into high-value fuels and chemicals.

HUSA is expected to close on the AGIG acquisition early in the second quarter and says the deal aims to provide value through “innovation in the renewable energy sector,” according to a news release.

As part of the deal, HUSA will acquire 100% of AGIG’s issued and outstanding units. HUSA will also issue to AGIG’s members a number of shares of HUSA common stock that will equal 94 percent of HUSA’s aggregate issued and outstanding common stock at the time of the closing. The company also closed a $4.42 million registered direct offering in January.

“AGIG has developed a commercially ready project for converting waste into valuable fuels and chemicals, and this transaction gives HUSA shareholders a ready-made platform and project pipeline for future value generation,” Peter Longo, CEO of Houston American Energy Corp, said in a news release. “We are witnessing the growing momentum of the fuel and chemical industry’s transformation into alternative solutions like recycled chemical alternatives and the highly publicized sustainable aviation fuel market.”

AGIG will build its first advanced plastic recycling facility in the Cedar Port Industrial Park in the Baytown area of Houston. The facility will represent the first phase of a growth plan aimed at scaling AGIG’s technologies for producing renewable fuels and chemicals from waste, according to the company. The Cedar Port facility will serve as a hub for a five-year development plan and will be designed to scale production capacity.

"We are excited to use this platform to support the deployment and development of our suite of technologies that will assist in the evolution of fuel, chemical and waste markets, providing commercial alternatives and sustainable products,” AGIG CEO Ed Gillespie said in a news release.

Supreme Court confronts what to do with growing pile of nuclear waste

The Debate Continues

The Supreme Court will hear arguments Wednesday in a fight over plans to store nuclear waste at sites in rural Texas and New Mexico.President Joe Biden's administration and a private company with a license for the Texas facility appealed a ruling by the 5th U.S. Circuit Court of Appeals that found that the Nuclear Regulatory Commission exceeded its authority in granting the license. The outcome of the case will affect plans for a similar facility in New Mexico roughly 40 miles away.

On this issue, President Donald Trump's administration is sticking with the views of its predecessor, even with Texas Gov. Greg Abbott, a Republican ally of Trump, on the other side.

The push for temporary storage sites is part of the complicated politics of the nation’s so far futile quest for a permanent underground storage facility.

Here's what to know about the case.

Where is spent nuclear fuel stored now?

Roughly 100,000 tons of spent fuel, some of it dating from the 1980s, is piling up at current and former nuclear plant sites nationwide and growing by more than 2,000 tons a year. The waste was meant to be kept there temporarily before being deposited deep underground.

A plan to build a national storage facility northwest of Las Vegas at Yucca Mountain has been mothballed because of staunch opposition from most Nevada residents and officials.

The Nuclear Regulatory Commission has said that the temporary storage sites are needed because existing nuclear plants are running out of room. The presence of the spent fuel also complicates plans to decommission some plants, the Justice Department said in court papers.

Where would it go?

The NRC granted the Texas license to Interim Storage Partners LLC for a facility that could take up to 5,000 metric tons of spent nuclear fuel rods from power plants and 231 million tons of other radioactive waste. The facility would be built next to an existing dump site in Andrews County for low-level waste, such as protective clothing and other material that has been exposed to radioactivity. The Andrews County site is about 350 miles west of Dallas, near the Texas-New Mexico state line.

The New Mexico facility would be in Lea County, in the southeastern part of the state near Carlsbad. The NRC gave a license for the site to Holtec International.

The licenses would allow for 40 years of storage, although opponents contend the facilities would be open indefinitely because of the impasse over permanent storage.

Political opposition is bipartisan

Republicans and Democrats, environmental groups and the oil and gas industry all oppose the temporary sites.

Abbott is leading Texas' opposition to the storage facility. New Mexico Democratic Gov. Michelle Lujan Grisham also is opposed to the facility planned for her state.

A brief led by Republican Texas Sen. Ted Cruz on behalf of several lawmakers calls the nuclear waste contemplated for the two facilities an “enticing target for terrorists” and argues it's too risky to build the facility atop the Permian Basin, the giant oil and natural gas region that straddles Texas and New Mexico.

Elected leaders of communities on the routes the spent fuel likely would take to New Mexico and Texas also are opposed.

What are the issues before the court?

The justices will consider whether, as the NRC argues, the states forfeited their right to object to the licensing decisions because they declined to join in the commission’s proceedings.

Two other federal appeals courts, in Denver and Washington, that weighed the same issue ruled for the agency. Only the 5th Circuit allowed the cases to proceed.

The second issue is whether federal law allows the commission to license temporary storage sites. Opponents are relying on a 2022 Supreme Court decision that held that Congress must act with specificity when it wants to give an agency the authority to regulate on an issue of major national significance. In ruling for Texas, the 5th Circuit agreed that what to do with the nation’s nuclear waste is the sort of “major question” that Congress must speak to directly.

But the Justice Department has argued that the commission has long-standing authority to deal with nuclear waste reaching back to the 1954 Atomic Energy Act.
