A fresh $12 million round of funding will enable Houston-based Citroniq Chemicals to propel planning, design, and construction of its first decarbonization plant.

An unidentified multinational energy technology company led the series A round, with participation from Houston-based Lummus Technology Ventures and cooperation from the State of Nebraska. The Citroniq plant, which will produce green polypropylene, will be located in Nebraska.

“Lummus’ latest investment in Citroniq builds on this progress and strengthens our partnership, working together to lower carbon emissions in the plastics industry,” Leon de Bruyn, president and CEO of Lummus Technology, says in a news release.

Citroniq is putting together a decarbonization platform designed to annually capture 2 million metric tons of greenhouse gas emissions at each plant. The company plans to invest more than $5 billion into its green polypropylene plants. Polypropylene is a thermoplastic resin commonly used for injection molding.

The series A round “is just the first step in our journey towards building multiple biomanufacturing hubs, boosting the Nebraska bioeconomy by converting local ethanol into valuable bioplastics,” says Kelly Knopp, co-founder and CEO of Citroniq.

Citroniq’s platform for the chemical and plastics industries uses technology and U.S.-produced ethanol to enable low-cost carbon capture. Citroniq’s process permanently sequesters carbon into a useful plastic pellet.

Lummus Technology licenses process technologies for clean fuels, renewables, petrochemicals, polymers, gas processing and supply lifecycle services, catalysts, proprietary equipment, and digital transformation.

Houston clean energy provider raises $10.8M series A

money moves

A tech-driven retail energy provider based in Houston has secured an oversubscribed series A round of funding.

Branch Energy raised a $10.8 million round led by climate-focused venture capital firm Prelude Ventures with co-investor Zero Infinity Partners, an infrastructure tech-focused firm. The fresh funding will go toward accelerating the company's battery management tech and build out the infrastructure of its field services.

A vertically integrated power provider, Branch Energy aims to provide customers with demand management software and battery storage systems to ensure long-term, stable, and clean energy at a lower cost than competitors.

“Our century-old grid design is not equipped for the complexity of today’s energy needs," Alex Ince-Cushman, Branch Energy co-founder and CEO, says in a news release. “Optimizing distributed energy assets in real-time will play an increasingly important role in managing the grid. We built Branch from the ground up as a technology company, allowing us to deliver value to customers in this new era of distributed energy by reducing costs while improving reliability."

The company chose Texas as its inaugural market based on the stress of the grid in the state, the company says in the release. Since 2021 when Branch Energy launched, it has signed up thousands of customers for its 100 percent clean energy service. The business proposition includes lowering customer's energy bills by 5 to 10 percent.

“The power grid, especially in Texas, requires distributed generation and flexible loads as basic economics drives deployment of more renewable resources,” Tim Woodward, managing partner at Prelude Ventures, adds. “Across the country, we are experiencing a major shift toward a decentralized and decarbonized grid. Branch Energy is bringing value to its customers through deployment of intelligent storage that lowers costs and improves reliability.”

Branch Energy, which is available now in some Texas regions, had previously raised $5.5 million in seed and pre-seed funding, per Crunchbase.

Houston agriculture robotics co. raises $21.5M series A to grow climatetech solution

freshly funded

A Houston energy tech startup has raised a $21.5 million series a round of funding to support the advancement of its automated technology that converts field wastes into stable carbon.

Applied Carbon, previously known as Climate Robotics, announced that its fresh round of funding was led by TO VC, with participation from Congruent Ventures, Grantham Foundation, Microsoft Climate Innovation Fund, S2G Ventures, Overture.vc, Wireframe Ventures, Autodesk Foundation, Anglo American, Susquehanna Foundation, US Endowment for Forestry and Communities, TELUS Pollinator Fund for Good, and Elemental Excelerator.

The series A funding will support the deployment of its biochar machines across Texas, Oklahoma, Arkansas, and Louisiana.

"Multiple independent studies indicate that converting crop waste into biochar has the potential to remove gigatons of CO2 from the atmosphere each year, while creating trillions of dollars in value for the world's farmers," Jason Aramburu, co-founder and CEO of Applied Carbon, says in a news release. "However, there is no commercially available technology to convert these wastes at low cost.

"Applied Carbon's patented in-field biochar production system is the first solution that can convert crop waste into biochar at a scale and a cost that makes sense for broad acre farming," he continues.

Applied Carbon rebranded in June shortly after being named a top 20 finalist in XPRIZE's four-year, $100 million global Carbon Removal Competition. The company also was named a semi-finalist and awarded $50,000 from the Department of Energy's Carbon Dioxide Removal Purchase Pilot Prize program in May.

"Up to one-third of excess CO2 that has accumulated in the atmosphere since the start of human civilization has come from humans disturbing soil through agriculture," Joshua Phitoussi, co-founder and managing partner at TO VC, adds. "To reach our net-zero objectives, we need to put that carbon back where it belongs.

"Biochar is unique in its potential to do so at a permanence and price point that are conducive to mass-scale adoption of carbon dioxide removal solutions, while also leaving farmers and consumers better off thanks to better soil health and nutrition," he continues. "Thanks to its technology and business model, Applied Carbon is the only company that turns that potential into reality."

The company's robotic technology works in field, picking up agricultural crop residue following harvesting and converts it into biochar in a single pass. The benefits included increasing soil health, improving agronomic productivity, and reducing lime and fertilizer requirements, while also providing a carbon removal and storage solution.

"We've been looking at the biochar sector for over a decade and Applied Carbon's in-field proposition is incredibly compelling," adds Joshua Posamentier, co-founder and managing partner of Congruent Ventures. "The two most exciting things about this approach are that it profitably swings the agricultural sector from carbon positive to carbon negative and that it can get to world-scale impact, on a meaningful timeline, while saving farmers money."

Chesapeake Energy backs Houston geothermal tech co. in $17M series A

fresh funding

A Houston geothermal startup has announced the close of its series A round of funding.

Houston-based Sage Geosystems announced the first close of $17 million round led by Chesapeake Energy Corp. The proceeds aim to fund its first commercial geopressured geothermal system facility, which will be built in Texas in Q4 of 2024. According to the company, the facility will be the first of its kind.

The venture is joined by technology investor Arch Meredith, Helium-3 Ventures and will include support from existing investors Virya, LLC, Nabors Industries Ltd., and Ignis Energy Inc.

“The first close of our Series A funding and our commercial facility are significant milestones in our mission to make geopressured geothermal system technologies a reality,” Cindy Taff, CEO of Sage Geosystems, says in a news release. “The success of our GGS technologies is not only critical to Sage Geosystems becoming post-revenue, but it is an essential step in accelerating the development of this proprietary geothermal baseload approach. This progress would not be possible without the ongoing support from our existing investors, and we look forward to continuing this work with our new investors.”

The 3-megawatt commercial facility will be called EarthStore and will use Sage’s technology that harvests energy from pressurized water from underground. The facility will be able to store energy — for short and long periods of time — and can be paired with intermittent renewable energy sources like wind and solar. It will also be able to provide baseload, dispatchable power, and inertia to the electric grid.

In 2023, Sage Geosystems debuted the EarthStore system in a full-scale commercial pilot project in Texas. The pilot produced 200 kilowatt for more than 18 hours, 1 megawatt for 30 minutes, and generated electricity with Pelton turbines. The system had a water loss of less than 2 percent and a round-trip efficiency (RTE) of 70-75.

ERCOT steps up grid innovation efforts to support growing power demand

grid boost

As AI data centers gobble up more electricity, the Electric Reliability Council of Texas (ERCOT) — whose grid supplies power to 90 percent of Texas — has launched an initiative to help meet challenges presented by an increasingly strained power grid.

ERCOT, based in the Austin suburb of Taylor, said its new Grid Research, Innovation, and Transformation (GRIT) initiative will tackle research and prototyping of emerging technology and concepts to “deeply understand the implications of rapid grid and technology evolution, positioning ERCOT to lead in the future energy landscape.”

“As the ERCOT grid continues to rapidly evolve, we are seeing greater interest from industry and academia to collaborate on new tools and innovative technologies to advance the reliability needs of tomorrow’s energy systems,” ERCOT President and CEO Pablo Vegas said in a news release. “These efforts will provide an opportunity to share ideas and bring new innovations forward, as we work together to lead the evolution and expansion of the electric power grid.”

In conjunction with the GRIT initiative, ERCOT launched the Research and Innovation Partnership Engagement (RIPE) program. The program enables partners to work with ERCOT on developing technology aimed at resolving grid challenges.

To capitalize on ideas for grid improvements, the organization will host its third annual ERCOT Innovation Summit on March 31 in Round Rock. The summit “brings together thought leaders across the energy research and innovation ecosystem to explore solutions that use innovation to impact grid transformation,” ERCOT said.

“As the depth of information and industry collaboration evolves, we will continue to enhance the GRIT webpages to create a dynamic and valuable resource for the broader industry to continue fostering strong collaboration and innovation with our stakeholders,” said Venkat Tirupati, ERCOT’s vice president of DevOps and grid transformation.

ERCOT’s GRIT initiative comes at a time when the U.S. is girding for heightened demand for power, due in large part to the rise of data centers catering to the AI boom.

A study released in 2024 by the Electric Power Research Institute (EPRI) predicted electricity for data centers could represent as much as 9.1 percent of total power usage in the U.S. by 2030. According to EPRI, the share of Texas electricity consumed by data centers could climb from 4.6 percent in 2023 to almost 11 percent by 2030.

A report issued in 2024 by the federal government’s Lawrence Berkeley National Laboratory envisions an even faster increase in data-center power usage. The report projected data centers will consume as much as 12 percent of U.S. electricity by 2028, up from 4.4 percent in 2023.

In 2023, the EPRI study estimated, 80 percent of the U.S. electrical load for data centers was concentrated in two states, led by Virginia and Texas. The University of Texas at Austin’s Center for Media Engagement reported in July that Texas is home to 350 data centers, second only to Virginia.

“The U.S. electricity sector is working hard to meet the growing demands of data centers, transportation electrification, crypto-mining, and industrial onshoring, while balancing decarbonization efforts,” David Porter, EPRI’s vice president of electrification and sustainable energy strategy, said. “The data center boom requires closer collaboration between large data center owners and developers, utilities, government, and other stakeholders to ensure that we can power the needs of AI while maintaining reliable, affordable power to all customers.”

Policy adviser tapped to lead ‘nuclear renaissance’ in Texas

going nuclear

As Texas places a $350 million bet on nuclear energy, a budget and policy adviser for Gov. Greg Abbott has been tapped to head the newly created Texas Advanced Nuclear Energy Office.

Jarred Shaffer is now director of the nuclear energy office, which administers the $350 million Texas Advanced Nuclear Development Fund. The fund will distribute grants earmarked for the development of more nuclear reactors in Texas.

Abbott said Shaffer’s expertise in energy will help Texas streamline nuclear regulations and guide “direct investments to spur a flourishing and competitive nuclear power industry in the Lone Star State. Texas will lead the nuclear renaissance.”

The Texas Nuclear Alliance says growth of nuclear power in the U.S. has stalled while China and Russia have made significant gains in the nuclear sector.

“As Texas considers its energy future, the time has come to invest in nuclear power — an energy source capable of ensuring grid reliability, economic opportunity, and energy and national security,” Reed Clay, president of the alliance, said.

“Texas is entering a pivotal moment and has a unique opportunity to lead. The rise of artificial intelligence and a rebounding manufacturing base will place unprecedented demands on our electricity infrastructure,” Clay added. “Meeting this moment will require consistent, dependable power, and with our business-friendly climate, streamlined regulatory processes, and energy-savvy workforce, we are well-positioned to become the hub for next-generation nuclear development.”

Abbott’s push for increased reliance on nuclear power in Texas comes as public support for the energy source grows. A 2024 survey commissioned by the Texas Public Policy Institute found 55 percent of Texans support nuclear energy. Nationwide support for nuclear power is even higher. A 2024 survey conducted by Bisconti Research showed a record-high 77 percent of Americans support nuclear energy.

Nuclear power accounted for 7.5 percent of Texas’ electricity as of 2024, according to the Nuclear Energy Institute, but made up a little over 20 percent of the state’s clean energy. Currently, four traditional reactors produce nuclear power at two plants in Texas. The total capacity of the four nuclear reactors is nearly 5,000 megawatts.

Because large nuclear plants take years to license and build, small factory-made modular reactors will meet much of the shorter-term demand for nuclear energy. A small modular reactor has a power capacity of up to 300 megawatts. That’s about one-third of the generating power of a traditional nuclear reactor, according to the International Atomic Energy Agency.

A report from BofA Global Research predicts the global market for small nuclear reactors could reach $1 trillion by 2050. These reactors are cheaper and safer than their larger counterparts, and take less time to build and produce fewer CO2 emissions, according to the report. Another report, this one from research company Bloomberg Intelligence, says soaring demand for electricity — driven mostly by AI data centers — will fuel a $350 billion boom in nuclear spending in the U.S., boosting output from reactors by 63 percent by 2050.

Global nuclear capacity must triple in size by 2050 to keep up with energy demand tied to the rise of power-gobbling AI data centers, and to accomplish decarbonization and energy security goals, the BofA report says. Data centers could account for nine percent of U.S. electricity demand by 2035, up from about four percent today, according to BloombergNEF.

As the Energy Capital of the World, Houston stands to play a pivotal role in the evolution of small and large nuclear reactors in Texas and around the world. Here are just three of the nuclear power advancements that are happening in and around Houston:

Houston is poised to grab a big chunk of the more than 100,000 jobs and more than $50 billion in economic benefits that Jimmy Glotfelty, a former member of the Texas Public Utility Commission, predicts Texas will gain from the state’s nuclear boom. He said nuclear energy legislation signed into law this year by Abbott will provide “a leg up on every other state” in the race to capitalize on the burgeoning nuclear economy.

“Everybody in the nuclear space would like to build plants here in Texas,” Inside Climate News quoted Glotfelty as saying. “We are the low-regulatory, low-cost state. We have the supply chain. We have the labor.”
