A new report from the University of Houston estimates that a method known as carbon dioxide-enhanced oil recovery (CO2-EOR) could recover roughly 137 billion barrels of U.S. oil—with Texas and the Gulf Coast poised to play a major role.

A UH Energy-produced white paper, titled “Revitalization of Mature Oil Fields: Opportunities and Challenges of CO2-EOR,” looks at how CO2-EOR could increase U.S. energy supply, reduce carbon emissions and lower the carbon intensity of oil production.

CO2-EOR injects pressurized carbon dioxide into mature oil wells to loosen and push oil trapped underground toward the production wells, allowing operators to extract oil typically left behind. The process permanently stores some CO2 underground, reducing carbon emissions and carbon intensity.

“Injected CO2 works to revitalize mature oil fields by reducing oil viscosity, improving sweep efficiency and restoring reservoir pressure, resulting in incremental oil production beyond primary and secondary recovery,” the report reads. “CO2-EOR also supports permanent carbon storage and by virtue of this will produce uniquely low-carbon intensity oil for global markets.”

Authored by Charles McConnell, executive director of UH's Center for Carbon Management in Energy, and Zhiyuan Li, a UH petroleum engineering doctoral candidate, the paper says that much of the opportunity lies right under the feet of Texas oil companies.

Texas and the Gulf Coast, including its offshore resources, have half of the nation's oil resources considered favorable for the CO2-EOR technology, the report says. According to UH, conventional U.S. oil reservoirs contain 624 billion barrels, with 434 billion barrels still underground, including about 20 billion barrels of proven reserves.

Still, the paper argues that the economics behind CO2-EOR need to be considered. The process’ success depends on a number of factors, including costs of carbon capture, field redevelopment, operations, monitoring, transportation and available tax incentives, according to UH.

Logistically, developing CO2-EOR operations out of older wells and infrastructure presents pros and cons. While using older wells can be more economical, aging infrastructure may require more frequent monitoring, inspection, repair or re-plugging, according to UH.

Ultimately, the report recommends focusing CO2-EOR development on mature oil fields with existing infrastructure, well-understood geology and reliable CO2 supplies. This approach, UH says, could help extend the productive life of existing oil fields while supporting “lower carbon intensity oil for global markets and a significant contribution to energy security.”

New UH white paper pushes for national plastics recycling policy

plastics paper

The latest white paper from the University of Houston’s Energy Transition Institute analyzes how the U.S. currently handles plastics recycling and advocates for a national, policy-driven approach.

Ramanan Krishnamoorti, vice president for energy and innovation at UH; Debalina Sengupta, assistant vice president and chief operating officer at the Energy Transition Institute; and UH researcher Aparajita Datta authored the paper titled “Extended Producer Responsibility (EPR) for Plastics Packaging: Gaps, Challenges and Opportunities for Policies in the United States.” In the paper, the scientists argue that the current mix of state laws and limited recycling infrastructure are holding back progress at the national level.

EPR policies assign responsibility for the end-of-life management of plastic packaging to producers or companies, instead of taxpayers, to incentivize better product design and reduce waste.

“My hope is this research will inform government agencies on what policies could be implemented that would improve how we approach repurposing plastics in the U.S.,” Krishnamoorti said in a news release. “Not only will this information identify policies that help reduce waste, but they could also prove to be a boon to the circular economy as they can identify economically beneficial pathways to recycle materials.”

The paper notes outdated recycling infrastructure and older technology as roadblocks.

Currently, only seven states have passed EPR laws for plastic packaging. Ten others are looking to pass similar measures, but each looks different, according to UH. Additionally, each state also has its own reporting system, which leads to incompatible datasets. Developing national EPR policies or consistent nationwide standards could lead to cleaner and more efficient processes, the report says.

The researchers also believe that investing in sorting, processing facilities, workforce training and artificial intelligence could alleviate issues for businesses—and particularly small businesses, which often lack the resources to manage complex reporting systems. Digital infrastructure techniques and moving away from manual data collection could also help.

Public education on recycling would also be “imperative” to the success of new policies, the report adds.

“Experts repeatedly underscored that public education and awareness about EPR, including among policymakers, are dismal,” the report reads. “Infrastructural limitations, barriers to access and the prevailing belief that curbside recycling is ineffective in the U.S. contribute to public dissatisfaction, misinformation and, in some cases, opposition toward the use of taxpayers’ and ratepayers’ contributions for EPR.”

Research from Rice University that merges biology with electrochemistry has uncovered new findings on how some bacteria generate electricity. Research showed how some bacteria use compounds called naphthoquinones, rather than oxygen, to transfer electrons to external surfaces in a process known as extracellular respiration. In other words, the bacteria are exhale electricity as they breathe. This process has been observed by scientists for years, but the Rice team's deeper understanding of its mechanism is a major breakthrough, with implications for the clean energy and industrial biotechnology sectors, according to the university.

A study from researchers at Rice University could lead to future advances in superconductors with the potential to transform energy use. The study revealed that electrons in strange metals, which exhibit unusual resistance to electricity and behave strangely at low temperatures, become more entangled at a specific tipping point, shedding new light on these materials. The materials share a close connection with high-temperature superconductors, which have the potential to transmit electricity without energy loss, according to the researchers. By unblocking their properties, researchers believe this could revolutionize power grids and make energy transmission more efficient.

A new study by researchers from Rice University’s Department of Materials Science and NanoEngineering, Baylor University and the Indian Institute of Science Education and Research Thiruvananthapuram has introduced a solution that could help develop more affordable and sustainable sodium-ion batteries. The team worked with tiny cone- and disc-shaped carbon materials from oil and gas industry byproducts with a pure graphitic structure. The forms allow for more efficient energy storage with larger sodium and potassium ions, which is a challenge for anodes in battery research. Sodium and potassium are more widely available and cheaper than lithium.

Engineers at Rice University have developed a cleaner, innovative process to turn end-of-life lithium-ion battery waste into new lithium feedstock. The findings demonstrate how the team’s new “recharge-to-recycle” reactor recharges the battery’s waste cathode materials to coax out lithium ions into water. The team was then able to form high-purity lithium hydroxide, which was clean enough to feed directly back into battery manufacturing. The study has major implications for the electric vehicle sector, which significantly contributes to the waste stream from end-of-life battery packs.

Collaborators from two Houston universities are leading the way in engineering a biomaterial into a scalable, multifunctional material that could potentially replace plastic. The study introduced a biosynthesis technique that aligns bacterial cellulose fibers in real-time, which resulted in robust biopolymer sheets with “exceptional mechanical properties.” Ultimately, the scientists hope this discovery could be used for the “next disposable water bottle,” which would be made by biodegradable biopolymers in bacterial cellulose, an abundant resource on Earth. Additionally, the team sees applications for the materials in the packaging, breathable textiles, electronics, food and energy sectors.

UH's $44 million mass timber building slashed energy use in first year

building up

The University of Houston recently completed assessments on year one of the first mass timber project on campus, and the results show it has had a major impact.

Known as the Retail, Auxiliary, and Dining Center, or RAD Center, the $44 million building showed an 84 percent reduction in predicted energy use intensity, a measure of how much energy a building uses relative to its size, compared to similar buildings. Its Global Warming Potential rating, a ratio determined by the Intergovernmental Panel on Climate Change, shows a 39 percent reduction compared to the benchmark for other buildings of its type.

In comparison to similar structures, the RAD Center saved the equivalent of taking 472 gasoline-powered cars driven for one year off the road, according to architecture firm Perkins & Will.

The RAD Center was created in alignment with the AIA 2030 Commitment to carbon-neutral buildings, designed by Perkins & Will and constructed by Houston-based general contractor Turner Construction.

Perkins & Will’s work reduced the building's carbon footprint by incorporating lighter mass timber structural systems, which allowed the RAD Center to reuse the foundation, columns and beams of the building it replaced. Reused elements account for 45 percent of the RAD Center’s total mass, according to Perkins & Will.

Mass timber is considered a sustainable alternative to steel and concrete construction. The RAD Center, a 41,000-square-foot development, replaced the once popular Satellite, which was a food, retail and hangout center for students on UH’s campus near the Science & Research Building 2 and the Jack J. Valenti School of Communication.

The RAD Center uses more than a million pounds of timber, which can store over 650 metric tons of CO2. Aesthetically, the building complements the surrounding campus woodlands and offers students a view both inside and out.

“Spaces are designed to create a sense of serenity and calm in an ecologically-minded environment,” Diego Rozo, a senior project manager and associate principal at Perkins & Will, said in a news release. “They were conceptually inspired by the notion of ‘unleashing the senses’ – the design celebrating different sights, sounds, smells and tastes alongside the tactile nature of the timber.”

In addition to its mass timber design, the building was also part of an Energy Use Intensity (EUI) reduction effort. It features high-performance insulation and barriers, natural light to illuminate a building's interior, efficient indoor lighting fixtures, and optimized equipment, including HVAC systems.

The RAD Center officially opened Phase I in spring 2024. The third and final phase of construction is scheduled for this summer, with a planned opening set for the fall.

University plugs into Houston renewables co. as official athletics energy provider

go coogs

This college football season brings a lot of newness for the University of Houston: A new conference, following the athletic program's July transition to the Big 12. And a new official energy provider that is 100 percent renewable.

UH Athletics announced last week that Houston-based Rhythm Energy has signed on to be the official energy company of the program. The company will have a presence on signage at all sports venues, a strong digital presence across UH Athletics platforms; and Cougars’ basketball, baseball, softball, soccer, and track and field home events.

Rhythm Energy will also roll out The Go Coogs 12 Plan in time for football season, which will be an exclusive electricity plan to help UH faculty, alumni, students and fans go green.

“As a proud UH alumni, I am so pleased Rhythm Energy has become the Official Energy Company for my alma mater,” PJ Popovic, CEO of Rhythm Energy, said in a statement. “UH is hands down one of the top educational and athletic institutions in the nation, and I’m forever grateful for the knowledge I gained there, which allowed me to start my own renewable energy company. With UH joining the Big 12 Conference, we’re inspired by their success, achievements, and growth—something we strive for at Rhythm Energy every day.”

UH Athletics oversees 17 sport programs — seven on the men's side, including baseball, basketball, cross country, football, golf, and track and field, and 10 on the women's side, including basketball, cross country, golf, soccer, softball, swimming and diving, tennis, track and field, and volleyball.

Popovic founded Rhythm Energy in 2021. The company offers 100 percent renewable energy plans for Texas residents, using solar power, wind power and other renewable power sources.

The founder spoke with EnergyCapital last month about where he thinks renewables fit into Texas’ energy consumption and grid reliability issues and the shifting public opinion towards renewables.

"There is still a lot (speech) that is not necessarily painting renewables correctly," he tells EnergyCapital.

Houston named semifinalist for major NSF energy transition funding opportunity

ON TO THE NEXT ROUND

The National Science Foundation announced 34 semifinalists for a regional innovation program that will deploy up to $160 million in federal funding over the next 10 years. Among the list of potential regions to receive this influx of capital is Houston.

The Greater Houston Partnership and the Houston Energy Transition Initiative developed the application for the NSF Regional Innovation Engine competition in collaboration with economic, civic, and educational leaders from across the city and five regional universities, including the University of Houston, The University of Texas at Austin, Texas Southern University, Rice University, and Texas A&M University.

The proposed project for Houston — called the Accelerating Carbon-Neutral Technologies and Policies for Energy Transition, or ACT, Engine — emphasizes developing sustainable and equitable opportunities for innovators and entrepreneurs while also pursuing sustainable and equitable energy access for all.

“The ACT Engine will leverage our diverse energy innovation ecosystem and talent, creating a true competitive advantage for existing and new energy companies across our region," says Jane Stricker, senior vice president of energy transition and executive director for HETI, in a statement. "Texas is leading the way in nearly every energy and energy transition solution, and this Engine can catalyze our region’s continued growth in low-carbon technology development and deployment."

If Houston's proposal is selected as a finalist, it could receive up to $160 million over 10 years. The final list of NSF Engines awards is expected this fall, and, according to a release, each awardee will initially receiving about $15 million for the first two years.

"Each of these NSF Engines semifinalists represents an emerging hub of innovation and lends their talents and resources to form the fabric of NSF's vision to create opportunities everywhere and enable innovation anywhere," NSF Director Sethuraman Panchanathan says in a news release. "These teams will spring ideas, talent, pathways and resources to create vibrant innovation ecosystems all across our nation."

The NSF selected its 34 semifinalists from 188 original applicants, and the next step for Houston is a virtual site visit that will assess competitive advantages, budget and resource plans for R&D and workforce development, and the proposed leadership’s ability to mobilize plans into action over the first two years.

"Houston is poised, like no other city, to lead the energy transition. The ACT Engine presents a remarkable opportunity to not only leverage the region's unparalleled energy resources and expertise but also harness our can-do spirit. Houston has a proven track record of embracing challenges and finding innovative solutions,” says Renu Khator, president of the University of Houston, in the statement. “Through the collaborative efforts facilitated by the ACT Engine, I am confident that we can make significant strides towards creating a sustainable future that harmonizes economic growth, environmental protection and social equity."

NSF Engines will announce awards this fall after a round of in-person interviews of finalists named in July. With Houston's track record for building thriving industry hubs in energy, health care, aerospace, and the culinary arts, the region is eager to establish the next generation of leaders and dreamers responding to some of the greatest economic and societal challenges ever seen in America.

“Our energy innovation ecosystem is inclusive, dynamic, and fast growing," says Barbara Burger, energy transition adviser and former Chevron executive, in the release. "The ACT Engine has the potential to increase the amount of innovation coming into the ecosystem and the capabilities available to scale technologies needed in the energy transition. I am confident that the members of the ecosystem — incubators, accelerators, investors, universities, and corporates — are ready for the challenge that the ACT Engine will provide."

Houston geothermal companies secure more than $45M in DOE funding

geothermal boost

Three Houston-based companies—Fervo Energy, Quaise Energy and XGS Energy—have been selected by the U.S. Department of Energy to advance geothermal technologies and field tests.

Combined, the companies will receive more than $45 million in funding from the DOE's Next-Generation Geothermal Field Tests and Geothermal Resource Characterization and Confirmation initiative. The projects were among 21 selected from around the country to receive a total of $99 million.

Fervo was selected to conduct two projects under the initiative for approximately $20 million in funding. For the first project, the geothermal unicorn, which achieved first power at its flagship geothermal plant last week, will drill and complete enhanced geothermal systems (EGS) wells in Elmore County, Idaho, and will deploy high-temperature seismic monitoring technology at record-high temperatures at or above 200°C.

For the second project, the company will conduct an appraisal drilling campaign at a "high-priority" site in Humboldt County, Nevada, to confirm if the reservoir is suitable for EGS development.

“We are grateful to the Department of Energy for funding these grants. We believe this is a clear indication from the federal government that expanding geothermal energy to new states is a national priority,” Jack Norbeck, CTO and co-founder of Fervo Energy, said in a news release. “We expect this funding to accelerate Fervo’s pipeline and advance the cutting edge of geothermal technologies.”

Fresh off a $180 million Series B, Quaise Energy also received $25 million in DOE funding through the initiative to support its Project Obsidian super hot geothermal plant in Central Oregon. The funding will go toward the analysis of the drilling, stimulation and flow results of the first two wells at the Project Obsidian site, which will help the company optimize its third well on site.

“This DOE support is a recognition of what we are building at Quaise and the progress we are making in the field, including the confirmation well currently being drilled at Project Obsidian,” Carlos Araque, CEO and president of Quaise, said in a release. “Our ambition has always been to make superhot geothermal a commercial reality, and Project Obsidian is where we first deliver on that promise.”

XGS Energy, which recently relocated its headquarters from Palo Alto, California, to Houston, was also selected for an exploration drilling project. The company will drill a deep vertical appraisal well in Socorro County, New Mexico, to determine if the site is a viable source of geothermal energy. XGS had not disclosed a funding estimate at press time.

The full value of the proposed DOE funding is subject to completion of award negotiations, according to Quaise.

Data from these projects will be shared through DOE’s Geothermal Data Repository (GDR), providing valuable information to researchers and stakeholders in the geothermal sector.

“This is an excellent example of how public and private entities can partner together to scale critical energy technologies,” Tim Latimer, CEO and co-founder of Fervo, added in a release. “With this funding, the Department of Energy is making important investments to help Americans across the country gain access to clean, affordable geothermal energy.”

Other geothermal companies and institutions from around the country will complete the 17 remaining projects. They include:

  • Denver-based 400C Energy Inc.
  • Salt Lake City-based AlterG Resources
  • Denver-based DAVINCI EP LLC
  • Anchorage-based GeoAlaska LLC
  • Oklahoma City-based GreenFire Energy Inc.
  • Virginia-based Hexagon Energy LLC
  • Virginia-based INTEK Inc.
  • Chicago-based Invenergy Geothermal Development LLC
  • Massachusetts-based LiPower Geothermal LLC
  • Fort Worth-based Oriah Geothermal LLC
  • Reno-based Raser Power Systems LLC
  • Santa Fe-based San Ildefonso Services LLC
  • Salt Lake City-based The University of Utah

CenterPoint gets $50M DOE grant to improve Houston power grid

grid grant

A $50 million federal grant will help Houston-based CenterPoint Energy strengthen Houston’s power grid.

The U.S. Department of Energy (DOE) grant will support power substation upgrades in the Houston area.

“Our mission is to build the most resilient coastal grid in the nation for the 2.9 million customers we proudly serve in the greater Houston area … [The grant] will directly fund industry-leading technology improvements that are expected to strengthen resiliency, reliability, and meet the growing energy needs of our region,” Jason Ryan, CenterPoint Energy’s executive vice president for regulatory services and government affairs, said in a release.

CenterPoint says the project will make it one of the first U.S. utilities to install Siemens Energy’s grid-stabilizing technology.

The project will create more than 500 construction and installation jobs, CenterPoint says.

“Generations of CenterPoint customers and families in the region will benefit from the advanced technology this grant is funding,” said Kathleen Jackson, a member of the Public Utility Commission of Texas. “And any time companies make improvements like this to their systems, the long-term impact is making the entire grid stronger for Texans.”

The $176.7 million substation project is part of CenterPoint’s Greater Houston Resiliency Initiative, which launched in 2024.

So far, the initiative has:

  • Installed nearly 82,400 storm-resilient poles and equipment
  • Trimmed and cleared more than 13,700 miles of trees and vegetation near power lines
  • Added nearly 820 grid automation and intelligence devices
  • Put more than 880 miles of power lines underground

The initiative kicked off three years after Winter Storm Uri. CenterPoint received harsh criticism for what customers complained was the utility’s slow response to the 2021 storm. Uri caused a massive power outage and at least 246 deaths across Texas.

CenterPoint blamed the Electric Reliability Council of Texas (ERCOT), which operates the power grid for most Texans, for not supplying the utility with enough electricity during and after the storm.
