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.

$360M DOE grant to fund project that will connect ERCOT to grids in other states for first time

powering on

For the first time ever, the power grid for the territory served by the Electric Reliability Council of Texas (ERCOT) will be connected to grids in other states.

Officials hope building a 320-mile transmission line that connects the ERCOT electric grid to electric grids in the Southeast will prevent power outages like the massive blackout that occurred in 2022 when a winter storm blasted Texas.

San Francisco-based Pattern Energy says its Southern Spirit project will cost more than $2.6 billion. Full-scale construction is supposed to get underway in 2028, and the project is set to go online in 2031.

The U.S. Department of Energy recently approved up to $360 million for the transmission project. The transmission line will stretch from Texas’ border with Louisiana to Mississippi. It’ll supply about 3,000 megawatts of electricity in either direction. That’s enough power for about 750,000 residential customers during ERCOT’s peak hours.

ERCOT’s more than 54,100 miles of transmission lines supply power to about 90 percent of Texans.

“The U.S. transmission network is the backbone of our nation’s electricity system. Though our grid has served U.S. energy needs for more than a century, our country’s needs are changing,” David Turk, under secretary at the Department of Energy, says in a news release.

“DOE’s approach to deploying near-term solutions and developing long-term planning tools will ensure our electric grid is more interconnected and resilient than ever before,” Turk adds, “while also supporting greater electricity demand.”

The other three projects that recently received funding from the DOE include:

Aroostook Renewable Project, which will construct a new substation in Haynesville, Maine, and a 111-mile transmission line connecting to a substation in Pittsfield, Maine.
Cimarron Link, a 400-mile HVDC transmission line from Texas County, Oklahoma to Tulsa, Oklahoma
Southline, which will construct a 108-mile transmission line between Hidalgo County, New Mexico, and Las Cruces, New Mexico. The DOE previously supported a 175-mile line from Hidalgo County, New Mexico, to Pima County, Arizona, in Southline Phase 1 on the first round of the Transmission Facilitation Program.

This month's funding completes the $2.5 billion in awards from the Transmission Facilitation Program which is administered through the Building a Better Grid Initiative that launched in January 2022. Its mission has been to develop nationally significant transmission lines, increase resilience by connecting regions of the country and improve access to clean energy sources, according to the DOE.

Earlier this year, ERCOT, which manages 90 percent of Texas’ power supply, forecasted a major spike in demand for electricity over the next five to seven years

Law firm expands energy transition-focused, Houston-based team

new hire

An energy transition-focused legal team has on boarded its newest member.

Jenny Speck joined Vinson & Elkins as a Houston-based partner in its Energy Transition and Tax Practices. According to V&E, she will advise clients on energy transition tax incentives. Her experience includes working on renewable projects from onshore and offshore wind, solar, combined heat and power to biogas property, carbon capture, hydrogen, and more.

“Jenny has a commercial sensibility that our clients will value. She knows how to get deals done and is adept at calibrating tax advice to a company’s strategic objectives,” Vinson & Elkins Partner Sean Moran, one of the leaders of the firm’s Energy Transition Practice, says in a news release. “She is another phenomenal addition to our Renewable Energy and Tax Practices, which are booming as the Inflation Reduction Act continues to drive unprecedented investment and development in renewable energy.”

Joining V&E from Bracewell, Speck previously served as the senior manager of tax and regulatory compliance at Navigator CO2 Ventures LLC and also worked in the National Tax practice of Deloitte Tax LLP in Washington, D.C. She earned her undergraduate degree from Northeastern State University and her Juris Doctorate from the University of Tulsa College of Law. She's been ranked by Legal 500 U.S. and included in the Lawdragon 500 Leading US Energy Lawyers guide for “Energy Transition Incentives.”

“I have worked across from Vinson & Elkins on transactions and have seen the depth of their experience, along with the efficiency and camaraderie they bring to projects,” Speck adds. “I look forward to joining my new colleagues and strengthening their tax and energy powerhouse.”

She will work with partners Moran and Lauren Collins, who joined V&E along with four renewable energy and tax lawyers in 2021, as well as Jorge Medina, who was on boarded to the team earlier this year.

An aircraft that's being touted as the first fully electric jet is taking off from Hobby Airport to serve the greater Houston area.

Lilium Jet, which takes off and lands vertically, is making its United States market debut at Houston-area facilities – Houston Hobby Airport, Conroe North Houston Regional Airport, and The Woodlands Heliport Lilium. Houston-based aircraft brokerage EMCJET will house the Lilium Jet at its Galaxy FBO Houston-area facilities at the airports.

The Lilium Jet is capable of quickly connecting routes like Houston Hobby Airport to Galveston, Houston Spaceport to College Station, The Woodlands to Galveston, and others. The jet is designed for regional travel with its aerodynamic shape. The ducted electric fans prioritize efficiency and speed during forward flight. The jet’s anticipated initial operating range is roughly 110 miles. Lilium aims for the first piloted flight of the Lilium Jet to occur early in 2025. Read more.
