Houston-based Envana Software Solutions has received more than $5.2 million in federal and non-federal funding to support the development of technology for the oil and gas sector to monitor and reduce methane emissions.

Thanks to the work backed by the new funding, Envana says its suite of emissions management software will become the industry's first technology to allow an oil and gas company to obtain a full inventory of greenhouse gases.

The funding comes from a more than $4.2 million grant from the U.S. Department of Energy (DOE) and more than $1 million in non-federal funding.

“Methane is many times more potent than carbon dioxide and is responsible for approximately one-third of the warming from greenhouse gases occurring today,” Brad Crabtree, assistant secretary at DOE, said in 2024.

With the funding, Envana will expand artificial intelligence (AI) and physics-based models to help detect and track methane emissions at oil and gas facilities.

“We’re excited to strengthen our position as a leader in emissions and carbon management by integrating critical scientific and operational capabilities. These advancements will empower operators to achieve their methane mitigation targets, fulfill their sustainability objectives, and uphold their ESG commitments with greater efficiency and impact,” says Nagaraj Srinivasan, co-lead director of Envana.

In conjunction with this newly funded project, Envana will team up with universities and industry associations in Texas to:

Advance work on the mitigation of methane emissions
Set up internship programs
Boost workforce development
Promote environmental causes

Envana, a software-as-a-service (SaaS) startup, provides emissions management technology to forecast, track, measure and report industrial data for greenhouse gas emissions.

Founded in 2023, Envana is a joint venture between Houston-based Halliburton, a provider of products and services for the energy industry, and New York City-based Siguler Guff, a private equity firm. Siguler Gulf maintains an office in Houston.

“Envana provides breakthrough SaaS emissions management solutions and is the latest example of how innovation adds to sustainability in the oil and gas industry,” Rami Yassine, a senior vice president at Halliburton, said when the joint venture was announced.

DOE dishes out funding to 2 Houston carbon caption projects

ccus news

Two Houston companies have received federal funding to develop carbon capture and storage projects.

Evergreen Sequestration Hub LLC, a partnership of Houston-based Trace Carbon Solutions and Jacksonville, Mississippi-based Molpus Woodlands Group, got more than $27.8 million from the U.S. Department of Energy for its Evergreen Sequestration Hub project in Louisiana. DOE says the project is valued at $34.8 million.

The hub will be built on about 20,000 acres of timberland in Louisiana’s Calcasieu and Beauregard parishes for an unidentified customer. It’ll be capable of storing about 250 million metric tons of carbon dioxide.

Trace Carbon Solutions, a subsidiary of Trace Midstream Partners, is developing CCS assets and supporting midstream infrastructure across North America. Molpus, an investment advisory firm, buys, manages, and sells timberland as an investment vehicle for pension funds, college endowments, foundations, insurance companies, and high-net-worth investors.

Another Houston company, RPS Expansion LLC, has received $9 million from the DOE to expand the River Parish Sequestration Project. Following the expansion, the project will be able to store up to 384 million metric tons of carbon dioxide. The CCUS hub is between Baton Rouge and New Orleans.

DOE says the River Parish expansion is valued at $11.8 million.

Also receiving DOE funding is a CCUS project to be developed off the coast of Corpus Christi. The developer is the Southern States Energy Board, based in Peachtree Corners, Georgia.

DOE is chipping in more than $51.1 million for the nearly $64 million hub. It’s estimated that about 35 million metric tons of carbon dioxide emissions are released each year from about 50 industrial and power facilities within a 100-mile radius of Mustang Island. Port Aransas is located on the 18-mile-long island.

In all, DOE recently allocated $518 million to 23 CCUS projects in the U.S.

“The funding … will help ensure that carbon storage projects — crucial to slashing harmful carbon pollution — are designed, built, and operated safely and responsibly across all phases of development to deliver healthier communities as well as high-quality American jobs,” Brad Crabtree, assistant DOE secretary for fossil energy and carbon management, says in a news release.

top of class

A team of students from the University of Houston have placed in the top three teams for a national competition for the Department of Energy.

The inaugural American-Made Carbon Management Collegiate Competition, hosted by the U.S. Department of Energy's Office of Fossil Energy and Carbon Management, or FECM, tasked the student teams with "proposing regional carbon networks capable of transporting at least one million metric tons of carbon dioxide per year from industrial sources," according to a news release from DOE.

“With this competition, DOE hopes to inspire the next generation of carbon management professionals to develop carbon dioxide transport infrastructure that will help drive technological innovation and emissions reductions, new regional economic development, and high-wage employment for communities across the United States,” Brad Crabtree, assistant secretary of fossil energy and carbon management at DOE, says in the release.

GreenHouston, the University of Houston team mentored by Assistant Professor Jian Shi from the UH Cullen College of Engineering, took third place in the competition, securing a $5,000 cash prize. Sequestration Squad of University of Michigan secured first place and $12,000 and Biggest Little Lithium of the University of Nevada won second and a $8,000 prize.

The UH team's proposal was for an optimized carbon dioxide transportation pipeline for the Houston area. The presentation included cost analysis, revenue potential, safety considerations, weather hazards, and social impact on neighboring communities, according to a release from UH.

“We chose the greater Houston metropolitan area as our target transition area because it is a global hub of the hydrocarbon energy industry,” says Fatemeh Kalantari, team leader, in the release.

“Our team was committed to delivering an optimized and cost-effective carbon dioxide transfer plan in the Houston area, with a focus on safety, environmental justice, and social engagement,” she continues. “Our goal is to ensure the health and safety of the diverse population residing in Houston by mitigating the harmful effects of carbon dioxide emissions from refineries and industries in the area, thus avoiding environmental toxicity.”

With the third place win, GreenHouston will get to present their proposal at DOE’s annual Carbon Management Research Project Review Meeting slated for August.

"We are thrilled to see the exceptional work and dedication displayed by the GreenHouston team in this competition," said Ramanan Krishnamoorti, vice president of energy and innovation at UH. "The team’s innovative proposal exemplifies UH’s commitment to addressing the pressing global issue of carbon management and advancing sustainable practices. We wish the students continued success."

The team included four Cullen College of Engineering doctoral students from the Department of Electrical and Computer Engineering – Kalantari, Massiagbe Diabate, Steven Chen, and Simon Peter Nsah Abongmbo – and one student, Bethel O. Mbakaogu, pursuing his master’s degree in supply chain and logistics technology.

The prize money will go toward funding additional research, refining existing technologies, addressing remaining challenges and raising awareness of CCUS and its project, according to the release, as the team feels a responsibility to continue to work on the GreenHouston project.

“The energy landscape by 2050 will be characterized by reduced greenhouse gas emissions, cleaner air quality, and a more sustainable environment,” Kalantari says. “The transition to green energy will not only mitigate the harmful effects of carbon dioxide on climate change but also create new jobs, promote economic growth, and enhance energy security. This is important, and we want to be part of it.”

Houston startup wins Space Force contract to advance quantum energy generator

quantum contract

Houston-based quantum energy technology startup Casimir Inc. has been awarded an STTR Phase I contract from the U.S. Space Force's SpaceWERX to support the development of the company's solid-state generator for potential use by the Department of the Air Force.

SpaceWERX is the innovation arm of the U.S. Space Force and a division within AFWERX, the incubator and innovation arm of the United States Department of the Air Force. The Air Force Research Laboratory and SpaceWERX, along with many other government agencies, help support innovation through the Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) grants and contracts.

As part of the new contract, Casimir will work to refine a fully independent generator. Casimir’s solid-state power technology could support national security missions by providing reliable power even in difficult-to-service environments.

In May, Casimir emerged from stealth, netting a $12 million seed round to commercialize its quantum energy chip. The semiconductor chips can generate power from quantum vacuum fields without the need for batteries or charging. The company aims to include the chips in large-scale energy systems that can power homes, commercial infrastructure and electric vehicles.

“This STTR funds some analysis work to address our proposed scaling approach of making our chips multi-layer to increase aggregate power,” Harold “Sonny” White, founder and CEO of Casimir, tells Energy Capital.

White adds that the company will work with Texas A&M to develop chip planarization techniques to support Casimir’s plans to scale. Additionally, White says the company is working with the U.S. Space Force to explore more applications for its technology.

“Casimir’s technology brings a new capability to the market in the form of our persistent power chips,” White adds. “This approach will be relevant to ultra-low-power electronics, and with the scaling approach we are developing, connected with the STTR work, will eventually be relevant to consumer electronics and beyond.”

Casimir has previously reported that it plans to commercialize its first-generation MicroSparc chip by 2028. The chips are expected to power devices for years without the need for replacements.

The total funding for this project has not yet been disclosed.

Sage Geosystems brings South Texas geothermal plant online

powering up

Houston-based Sage Geosystems, a provider of geothermal power, has begun full operations at its South Texas facility for the San Miguel Electric Cooperative.

Sage says the plant was recently “placed in service,” according to a news release. This means it’s fully built and tested, and ready to generate and supply electricity to the grid.

Since selling its first electricity in Q2 of this year, the facility has been operating for more than four months to evaluate aspects like efficiency and water management. Sage relied on its GeoTwin modeling tool to carry out some of the testing.

The testing demonstrates Sage’s proprietary approach to geothermal power “overcomes one of the industry’s most persistent challenges, high water losses in engineered reservoirs, while delivering the consistent performance required to scale next-generation geothermal,” co-founder and CEO Cindy Taff said in the release.

Sage says the South Texas facility will serve as a model for future projects, including one in Nevada. The Nevada facility will use Sage’s proprietary technology to extract geothermal heat from hot dry rock, creating a reliable, affordable source of carbon-free power.

During the testing period, water losses amounted to less than 10 percent. This low rate indicates most water remains in the system, enabling Sage to capture more usable energy, boost power production and improve the project’s finances, the company says.

“Commercial geothermal isn’t just about creating a reservoir. It’s about creating one whose performance can be engineered, predicted, and consistent,” Lev Ring, the company’s co-founder, president and chief technology officer, said in the release.

Since being founded in 2020, Sage has raised $159 million in outside funding. This includes a more than $97 million Series B round co-led by Ormat Technologies and Carbon Direct Capital.

Two years ago, Sage announced a deal with Meta Platforms, the parent company of Facebook and Instagram, to supply up to 150 megawatts of geothermal power to Meta data centers.
