Last month’s Houston Livestock Show and Rodeo stirred up another rootin’ tootin’ time for Houstonians and beyond.

But before the annual event galloped into the sunset, there were quite a few memorable innovations on display, with one notably coming from Rheom Materials.

The Houston-based pioneer of next-generation materials presented its scalable, bio-based alternative known as Shorai, a 93 percent bio-based leather, through two custom, western-inspired outfits that showed off cowboy flair through a sustainable lens.

“I'm a Houstonian, I love the rodeo,” Megan Beck, Rheom’s business development manager, recalls. “We're sitting there talking about it one day and we're like, ‘Okay, we've got to do something with this leather to show people how good it can look in apparel, how easy it is to wear.’”

Buoyed by the idea that their materials are meant to “change your impact, not your life,” Rheom captured the real-life energy of their bio-leather outfits under the rodeo’s neon lights in a short commercial video and photo shoot with models donning the samples, while dancing and enjoying the festivities. Rheom created a skirt, a leather jacket, and then a leather top for the look.

“Houston is such a vibrant city,” Beck says. “There's so much innovation here. I think the rodeo is just a really, really great example of that. And so we wanted to take this opportunity to take some of these garments out there and go on the slide, go on some of the rides, go into the wine garden and go dancing, because if you've ever felt some of the materials in the market in this space, they're very stiff, you can't really move in them, they're a little fragile, they kind of fall apart.”

Not only do the models in the video look fashionable, but they also look comfortable, and the leather looks natural and supple. And to the naked eye, Shorai appears to be like the leather most wearers are accustomed to.

“What we really wanted to showcase in this is the energy and the movement of the leather, and to show people how good it can look in apparel, and how easy it is to wear, which I think we were able to accomplish,” Beck says.

Next up, Beck says Rheom wants to scale production of Shorai, the Japanese word for “future,” at a competitive price point, while also reducing its carbon footprint by 80 percent when compared to synthetic leather. According to Beck, Rheom plans to see Shorai products come to market sometime this year.

“We have companies globally right now that are testing materials, that are prototyping, that are making garments, making handbags and footwear, and making eyewear because we have a plastic, as well,” Beck says. “So, this year, I do believe we'll start seeing those products actually come to market, which is very, very exciting for us.”

And with their large-scale production partner already set up for Shorai, Rheom plans to start its first production run of the product soon.

“In April, we'll actually be starting our first production run,” Beck says. “We'll be doing it at full scale, full width, and a full run of materials. So over the next five years, we're only going to just try to increase that capacity.”

Houston researchers reach 'surprising' revelation in materials recycling efforts

keep it clean

Researchers at Rice University have published a study in the journal Carbon that demonstrates how carbon nanotube (CNT) fibers can be fully recycled without any loss in their structure or properties.

The discovery shows that CNT fibers could be used as a sustainable alternative to traditional materials like metals, polymers and the larger, harder-to-recycle carbon fibers, which the team hopes can pave the way for more sustainable and efficient recycling efforts.

“Recycling has long been a challenge in the materials industry — metals recycling is often inefficient and energy intensive, polymers tend to lose their properties after reprocessing and carbon fibers cannot be recycled at all, only downcycled by chopping them up into short pieces,” corresponding author Matteo Pasquali, director of Rice’s Carbon Hub and the A.J. Hartsook Professor of Chemical and Biomolecular Engineering, Materials Science and NanoEngineering and Chemistry, explained in a news release. “As CNT fibers are being scaled up, we asked whether and how these new materials could be recycled in the future .... We expected that recycling would be difficult and would lead to significant loss of properties. Surprisingly, we found that carbon nanotube fibers far exceed the recyclability potential of existing engineered materials, offering a solution to a major environmental issue.”

Rice researchers used a solution-spun CNT fiber that was created by dissolving fiber-grade commercial CNTs in chlorosulfonic acid, according to Rice. Mixing the two fibers led to complete redissolution and no sign of separation of the two source materials into different liquid phases. This redissolved material was spun into a mixed-source recycled fiber that retained the same structure and alignment, which was unprecedented.

Pasquali explained in a video release that the new material has properties that overlap with and could be a replacement for carbon fibers, kevlar, steel, copper and aluminum.

“This preservation of quality means CNT fibers can be used and reused in demanding applications without compromising performance, thus extending their lifecycle and reducing the need for new raw materials,” co-first author Ivan R. Siqueira, a recent doctoral graduate in Rice’s Department of Chemical and Biomolecular Engineering, said in a news release.

Other co-authors of the paper are Rice graduate alumni Oliver Dewey, now of DexMat; Steven Williams; Cedric Ginestra, now of LyondellBasell; Yingru Song, now a postdoctoral fellow at Purdue University; Rice undergraduate alumnus Juan De La Garza, now of Axiom Space; and Geoff Wehmeyer, assistant professor of mechanical engineering.

The research is part of the broader program of the Rice-led Carbon Hub, an initiative to develop a zero-emissions future. The work was also supported by the Department of Energy’s Advanced Research Project Agency, the Air Force Office of Scientific Research and a number of other organizations.

Pasquali recently led another team of Rice researchers to land a $4.1 million grant to optimize CNT synthesis. The funds came from Rice’s Carbon Hub and The Kavli Foundation. Read more here.

Houston biomaterials startup taps partner for commercial-scale production

next-gen news

A Houston-based next-gen material startup has revealed a new strategic partnership.

Rheom Materials, formerly known as Bucha Bio, has announced a strategic partnership with thermoplastic extrusion and lamination company Bixby International, which is part of Rheom Material’s goal for commercial-scale production of its novel biobased material, Shorai.

Shorai is a biobased leather alternative that meets criteria for many companies wanting to incorporate sustainable materials. Shorai performs like traditional leather, but offers scalable production at a competitive price point. Extruded as a continuous sheet and having more than 92 percent biobased content, Shorai achieves an 80 percent reduction in carbon footprint compared to synthetic leather, according to Rheom.

Rheom, which is backed by Houston-based New Climate Ventures, will be allowing Bixby International to take a minority ownership stake in Rheom Materials, as part of the deal.

“Partnering with Bixby International enables us to harness their extensive expertise in the extrusion industry and its entire supply chain, facilitating the successful scale-up of Shorai production,” Carolina Amin Ferril, CTO at Rheom Materials, says in a news release. “Their highly competitive and adaptable capabilities will allow us to offer more solutions and exceed our customers’ expectations.”

In late 2024, Rheom Materials started its first pilot-scale trial at the Bixby International facilities with the goal to produce Shorai for prototype samples.

"The scope of what we were doing — both on what raw materials we were using and what we were creating just kept expanding and growing," founder Zimri Hinshaw previously told InnovationMap.

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.
