Last month, Houston-based Rheom Materials and India’s conscious design studio Econock unveiled a collaborative capsule collection that signaled more than just a product launch.

Hosted at Lineapelle—long considered the global epicenter of the world's premier leather supply chain—in the vaulted exhibition halls of Rho-Fiera Milano, the collection centered around Rheom’s 91 percent bio-based leather alternative, Shorai.

It was a bold move, one that shifted sustainability from a concept discussed in panel sessions to garments that buyers could touch and wear.

The collection featured a bomber-style jacket, an asymmetrical skirt and a suite of accessories—all fabricated from Shorai.

The standout piece, a sculptural jacket featuring a funnel neck and dual-zip closure, was designed for movement, challenging assumptions about performance limitations in bio-based materials. The design of the asymmetrical skirt was drawn from Indian armored warrior traditions, according to Rheom, with biodegradable corozo fasteners.

Built as a modular wardrobe rather than isolated pieces, the collection reflects a shared belief between Rheom and Econock in designing objects that adapt to daily life, according to the companies.

The collection was born out of a new partnership between Rheom and Econock, focused on bringing biobased materials to the market. According to Rheom, the partnership solves a problem that has stalled the adoption of many next-gen textiles: supply chain friction.

While Rheom focuses on engineering scalable bio-based materials, New Delhi-based Econock brings the complementary design and manufacturing ecosystem that integrates artisans, circular materials and production expertise to translate the innovative material into finished goods.

"This partnership removes one of the biggest barriers brands face when adopting next-generation materials,” Megan Beck, Rheom’s director of product, shared in a news release. “By reducing friction across the supply chain, Rheom can connect brands directly with manufacturers who already know how to work with Shorai, making the transition to more sustainable materials far more accessible.”

Sanyam Kapur, advisor of growth and impact at Econock, added: “Our partnership with Rheom Materials represents the benchmark of responsible design where next-gen materials meet craft, creativity, and real-world scalability.”

Rheom, formerly known as Bucha Bio, has developed Shorai, a sustainable leather alternative that can be used for apparel, accessories, car interiors and more; and Benree, an alternative to plastic without the carbon footprint. In 2025, Rheom was a finalist for Startup of the Year in the Houston Innovation Awards.

Shorai is already used by fashion lines like Wuxly and LuckyNelly, according to Rheom. The company scaled production of the sugar-based material last year and says it is now produced in rolls that brands can take to market with the right manufacturer.

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.

Houston geothermal company picks Nevada site for commercial-scale project

coming soon

Sage Geosystems, a Houston-based developer of geothermal power systems, has chosen a site in Nevada for its commercial-scale Project Vector facility.

The company’s two-well enhanced geothermal system (EGS) will deliver around-the-clock geothermal heat to Ormat Technologies’ Blue Mountain geothermal power plant in Winnemucca, Nevada.

The startup expects to begin drilling the first well later this year, with the first electricity to be generated in 2027 and full-scale production to start in 2028.

In the Nevada system, fluid will circulate through an engineered subsurface reservoir, absorb heat from the surrounding rock and return heat to the surface. The heat will be delivered to the Blue Mountain plant for conversion into electricity.

Project Vector builds on the performance of Sage’s SMECI facility in South Texas. That facility’s results, combined with Sage’s digital twin platform, will be used to shape to the design and development of Project Vector.

Project Vector supports Sage’s growing commercial pipeline, including a 150-megawatt geothermal power agreement with Meta Platforms, the parent company of Facebook and Instagram.

“Blue Mountain is an ideal location for Sage to take the next step in continuing to commercialize our proprietary EGS approach,” Jason Peart, chief operating officer at Sage, said in a release. “By delivering geothermal heat into an existing power plant, Project Vector can demonstrate the model for bringing firm, 24/7 geothermal power to market at scale.”

Project Vector extends Sage’s relationship with Ormat.

In August 2025, Sage and Ormat agreed to accelerate commercialization of Sage’s geothermal technology at an Ormat power plant. This January, Ormat co-led Sage’s $97 million Series B funding round.

Sage, founded in 2020, has raised about $159 million across three funding rounds.

As the startup ramps up its ESG platform, Sage is targeting data centers as customers, among other large-scale users of electricity.

“The energy needs are huge, and they need it now,” CEO Cindy Taff said on Data Center Frontiers’ podcast. “They can’t depend on the grid anymore.”

Houston’s power advantage: Key takeaways from 2026 HETI Power Summit

The view from heti

Power has become a defining economic development issue as electricity demand rises across Texas.

Industrial expansion, advanced manufacturing, AI and data center growth are increasing the importance of reliable, affordable power delivered on the timelines major projects require.

The 2026 HETI Power Summit, titled Houston’s Power Advantage: Competing for Large-Load Growth, brought together leaders from utilities, power producers, large energy customers, technology and infrastructure providers, professional services firms and the public sector to examine how Houston can meet this moment.

Across keynotes, research report-outs, panel discussions and a fireside chat, a consistent theme emerged: Houston’s power advantage comes from the region’s ability to align utilities, customers, infrastructure, flexible demand, emerging solutions and regional partners around reliable, affordable and timely growth.

Reliability and Readiness

Public Utility Commission of Texas Commissioner Kathleen Jackson opened the summit by emphasizing reliability as the foundation for continued growth as Texas electricity demand rises.

Commissioner Jackson underscored the importance of sustained planning and investment to support new industrial, manufacturing and digital demand while maintaining a reliable power system. Remarks framed the morning’s broader discussion of how Houston can pair reliability with speed, affordability and long-term system readiness.

Scott Cockerham of FTI Consulting previewed HETI and FTI’s “Texas Power Market & Industry Assessment”. The research identifies accessibility, reliability, affordability, market flexibility and infrastructure readiness as key dimensions of regional competitiveness.

Leaders from FTI Consulting, Kroll, AWS and Constellation also discussed factors shaping major investment decisions, including reliability, infrastructure timelines, cost certainty, site readiness, community support and regional coordination.

For large customers, these factors must translate into credible project-level execution. Confidence in system performance, energization timelines and infrastructure plans can materially influence major capital commitments.

Building for the Houston We Want to Become

Jason Ryan of CenterPoint Energy challenged participants to plan now for the infrastructure needed to support Houston’s next phase of growth. Drawing on the idea that “what got you here won’t get you there,” Ryan urged the region to build infrastructure for “the Houston we want to become” and stay ahead of large-load demand.

A fireside discussion between CenterPoint Energy and Foxconn brought that challenge to the customer level. The conversation explored how early coordination between utilities and large customers can help advanced manufacturing projects move from site selection and planning to construction and operation.

Long-term growth will require continued investment in generation, transmission and distribution. In the near term, better use of existing infrastructure can create additional capacity.

HETI also shared findings from its Role of Efficiency & Demand Response to Meet Near-Term Regional Power Demand report. Energy efficiency can lower baseline electricity use, while demand response can shift or reduce demand during critical periods. Combined with supply-side investment, these tools can create grid headroom as longer-term infrastructure advances.

The summit’s closing panel, featuring leaders from Amperon, Enchanted Rock, EY and Quanta Services, expanded the discussion to emerging solutions. Panelists explored modular and flexible generation, advanced forecasting, grid intelligence and greater coordination among utilities, customers, infrastructure providers and communities.

Houston’s broader regional power landscape adds another dimension. Entergy Texas President and CEO Eli Viamontes described Southeast Texas as experiencing an “extraordinary trifecta of residential, industrial and data center growth.” His remarks highlighted how the MISO-facing portion of the region complements Houston’s ERCOT strengths through utility planning, generation and infrastructure investment, resource adequacy and coordination with major industrial customers.

Together, these approaches point to a broader strategy: invest for long-term demand while using flexibility, technology and regional coordination to create capacity for growth today.

From Power Advantage to Economic Advantage

Taken together, the Power Summit discussions point to a clear priority for Houston: translating power market and infrastructure strengths into coordinated execution.

Priority areas include earlier infrastructure planning, stronger site and project readiness, clearer pathways from projected demand to reliably served load, expanded efficiency and flexibility, and sustained coordination among utilities, customers, policymakers, communities, technology providers and economic development organizations.

HETI is advancing this work through research and convening efforts focused on Houston’s evolving power needs and economic competitiveness.

The 2026 Power Summit reinforced Houston’s strong foundation for power-intensive growth and the importance of aligning investment, reliability, flexibility and regional coordination around the next generation of economic opportunity.
