Houston startup unveils sustainable bio-based leather at the rodeo

sustainable materials

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 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.

Podcast: Houston bio-based materials founder rebrands, evolves future-focused sustainability startup

listen in

At first, Zimri T. Hinshaw just wanted to design a sustainable, vegan jacket inspired by bikers he saw in Tokyo. Now, he's running a bio-based materials company with two product lines and is ready to disrupt the fashion and automotive industries.

Hinshaw founded Rheom Materials (née Bucha Bio) in 2020, but a lot has changed since then. He moved the company from New York to Houston, built out a facility in Houston's East End Maker Hub, and rebranded to reflect the company's newest phase and extended product lines, deriving from dozens of different ingredients, including algae, seaweed, corn, other fruits and vegetables, and more.

"As a company, we pivoted our technology from growing kombucha sheets to grinding up bacteria nanocellulose from kombucha into our products and then we moved away from that entirely," Hinshaw says on the Houston Innovators Podcast. "Today, we're designing different materials that are more sustainable, and the inputs are varied."

Now, in addition to Rheom's leather-like alternative, Shorai, the company has a plastic-like material, Benree, that's 100 percent bio based.

"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," Hinshaw says.

With that major evolution past just kombucha-based textiles, it was time for a new name, ideated by the company's technical team. "Rheom" is the combination of "rheology" — the study of how polymers flow — and "form."

Rheom has also built a state-of-the-art chemicals testing lab at its new facility after moving into it early last year.

"We've got a ton of capabilities now — and we've been growing those since the beginning," Hinshaw says. "Now we have all this testing equipment — things that pull materials apart, things that test the flexibility of materials."

Next up, Rheom, which is backed by Houston-based New Climate Ventures, among other VCs, will raise a series A funding round to continue supporting its growth.

ERCOT approves $9.4B project to improve grid, meet data center demand

power project

The Electric Reliability Council of Texas, which manages the electric grid for 90 percent of Texans, is undertaking a $9.4 billion project to improve the reliability and efficiency of statewide power distribution. The initiative comes as ERCOT copes with escalating demand for electricity from data centers and cryptocurrency-mining facilities.

The project, approved Dec. 9 by ERCOT’s board, will involve building a 1,109-mile “super highway” of new 765-kilovolt transmission lines. One kilovolt equals 1,000 volts of electricity.

According to the Hoodline Dallas news site, the $9.4 billion project represents the five- to six-year first phase of ERCOT’s Strategic Transmission Expansion Plan (STEP). Hoodline says the plan, whose price tag is nearly $33 billion, calls for 2,468 miles of new 765-kilovolt power lines.

STEP will enable ERCOT to “move power longer distances with fewer losses,” Hoodline reports.

Upgrading the ERCOT grid is a key priority amid continued population growth in Texas, along with the state’s explosion of new data centers and cryptocurrency-mining facilities.

ERCOT says about 11,000 megawatts of new power generation capacity have been added to the ERCOT grid since last winter.

But in a report released ahead of the December board meeting, ERCOT says it received 225 requests this year from large power users to connect to its grid — a 270 percent uptick in the number of megawatts being sought by mega-users since last December. Nearly three-fourths (73 percent) of the requests came from data centers.

Allan Schurr, chief commercial officer of Houston-based Enchanted Rock, a provider of products and services for microgrids and onsite power generation, tells Energy Capital that the quickly expanding data center industry is putting “unprecedented pressure” on ERCOT’s grid.

“While the state has added new generation and transmission capacity, lengthy interconnection timelines and grid-planning limitations mean that supply and transmission are not keeping pace with this rapid expansion,” Schurr says. “This impacts both reliability and affordability.”

For families in Texas, this could result in higher energy bills, he says. Meanwhile, critical facilities like hospitals and grocery stores face a heightened challenge of preventing power outages during extreme weather or at other times when the ERCOT grid is taxed.

“I expect this trend to continue as AI and high-density computing grow, driving higher peak demand and greater grid variability — made even more complex by more renewables, extreme weather and other large energy users, like manufacturers,” Schurr says.

According to the Pew Research Center, data centers accounted for 4 percent of U.S. electricity use in 2024, and power demand from data centers is expected to more than double by 2030. Data centers that support the AI boom make up much of the rising demand.

In September, RBN Energy reported more than 10 massive data-center campuses had been announced in Texas, with dozens more planned. The Lone Star State is already home to roughly 400 data centers.

“Texas easily ranks among the nation’s top states for existing data centers, with only Virginia edging it out in both data-center count and associated power demand,” says RBN Energy.

Federal judge strikes Trump order blocking wind energy development

wind win

In a win for clean energy and wind projects in Texas and throughout the U.S., a federal judge struck down President Donald Trump’s “Day One” executive order that blocked wind energy development on federal lands and waters, the Associated Press reports.

Judge Patti Saris of the U.S. District Court for the District of Massachusetts vacated Trump’s executive order from Jan. 20, declaring it unlawful and calling it “arbitrary and capricious.”

The challenge was led by a group of state attorneys general from 17 states and Washington, D.C., which was led by New York Attorney General Letitia James. The coalition pushed back against Trump's order , arguing that the administration didn’t have the authority to halt project permitting, and that efforts would critically impact state economies, the energy industry, public health and climate relief efforts.

White House spokesperson Taylor Rogers told the Associated Press that wind projects were given unfair treatment during the Biden Administration and cited that the rest of the energy industry suffered from regulations.

According to the American Clean Power Association, wind is the largest source of renewable energy in the U.S. It provides 10 percent of the electricity generated—and growing. Texas leads the nation in wind electricity generation, accounting for 28 percent of the U.S. total in 2024, according to the U.S. Energy Information Administration.

Several clean-energy initiatives have been disrupted by recent policy changes, impacting Houston projects.

The Biden era Inflation Reduction Act’s 10-year hydrogen incentive was shortened under Trump’s One Big Beautiful Bill Act, prompting ExxonMobil to pause its Baytown low-carbon hydrogen project. That project — and two others in the Houston region — also lost federal support as part of a broader $700 million cancellation tied to DOE cuts.

Meanwhile, Texas House Democrats have urged the administration to restore a $250 million Solar for All grant that would have helped low-income households install solar panels.

Texas launches cryptocurrency reserve with $5 million Bitcoin purchase

Digital Deals

Texas has launched its new cryptocurrency reserve with a $5 million purchase of Bitcoin as the state continues to embrace the volatile and controversial digital currency.

The Texas Comptroller’s Office confirmed the purchase was made last month as a “placeholder investment” while the office works to contract with a cryptocurrency bank to manage its portfolio.

The purchase is one of the first of its kind by a state government, made during a year where the price of Bitcoin has exploded amid the embrace of the digital currency by President Donald Trump’s administration and the rapid expansion of crypto mines in Texas.

“The Texas Legislature passed a bold mandate to create the nation’s first Strategic Bitcoin Reserve,” acting Comptroller Kelly Hancock wrote in a statement. “Our goal for implementation is simple: build a secure reserve that strengthens the state’s balance sheet. Texas is leading the way once again, and we’re proud to do it.”

The purchase represents half of the $10 million the Legislature appropriated for the strategic reserve during this year’s legislative session, but just a sliver of the state’s $338 billion budget.

However, the purchase is still significant, making Texas the first state to fund a strategic cryptocurrency reserve. Arizona and New Hampshire have also passed laws to create similar strategic funds but have not yet purchased cryptocurrency.

Wisconsin and Michigan made pension fund investments in cryptocurrency last year.

The Comptroller’s office purchased the Bitcoin the morning of Nov. 20 when the price of a single bitcoin was $91,336, according to the Comptroller’s office. As of Friday afternoon, Bitcoin was worth slightly less than the price Texas paid, trading for $89,406.

University of Houston energy economist Ed Hirs questioned the state’s investment, pointing to Bitcoin’s volatility. That makes it a bad investment of taxpayer dollars when compared to more common investments in the stock and bond markets, he said.

“The ordinary mix [in investing] is one that goes away from volatility,” Hirs said. “The goal is to not lose to the market. Once the public decides this really has no intrinsic value, then it will be over, and taxpayers will be left holding the bag.”

The price of Bitcoin is down significantly from an all-time high of $126,080 in early October.

Lee Bratcher, president of the Texas Blockchain Council, argued the state is making a good investment because the price of Bitcoin has trended upward ever since it first launched in early 2009.

“It’s only a 16-year-old asset, so the volatility, both in the up and down direction, will smooth out over time,” Bratcher said. “We still want it to retain some of those volatility characteristics because that’s how we could see those upward moves that will benefit the state’s finances in the future.”

Bratcher said the timing of the state’s investment was shrewd because he believes it is unlikely to be valued this low again.

The investment comes at a time that the crypto industry has found a home in Texas.

Rural counties have become magnets for crypto mines ever since China banned crypto mining in 2021 and Gov. Greg Abbott declared “Texas is open for crypto business” in a post on social media.

The state is home to at least 27 Bitcoin facilities, according to the Texas Blockchain Council, making it the world’s top crypto mining spot. The two largest crypto mining facilities in the world call Texas home.

The industry has also come under criticism as it expands.

Critics point to the industry’s significant energy usage, with crypto mines in the state consuming 2,717 megawatts of power in 2023, according to the comptroller’s office. That is enough electricity to power roughly 680,000 homes.

Crypto mines use large amounts of electricity to run computers that run constantly to produce cryptocurrencies, which are decentralized digital currencies used as alternatives to government-backed traditional currencies.

A 2023 study by energy research and consulting firm Wood Mackenzie commissioned by The New York Times found that Texans’ electric bills had risen nearly 5%, or $1.8 billion per year, due to the increase in demand on the state power grid created by crypto mines.

Residents living near crypto mines have also complained that the amount of job creation promised by the facilities has not materialized and the noise of their operation is a nuisance.

“Texas should be reinvesting Texan’s tax money in things that truly bolster the economy long term, living wage, access to quality healthcare, world class public schools,” said state Sen. Molly Cook, D-Houston, who voted against the creation of the strategic fund. “Instead it feels like they’re almost gambling our money on something that is known to be really volatile and has not shown to be a tide that raises all boats.”

State Sen. Charles Schwertner, R-Georgetown, who authored the bill that created the fund, said at the time it passed that it will allow Texas to “lead and compete in the digital economy.”
