HEXAspec, a spinout from Rice University's Liu Idea Lab for Innovation and Entrepreneurship, was recently awarded a $500,000 National Science Foundation Partnership for Innovation grant.

The team says it will use the funding to continue enhancing semiconductor chips’ thermal conductivity to boost computing power. According to a release from Rice, HEXAspec has developed breakthrough inorganic fillers that allow graphic processing units (GPUs) to use less water and electricity and generate less heat.

The technology has major implications for the future of computing with AI sustainably.

“With the huge scale of investment in new computing infrastructure, the problem of managing the heat produced by these GPUs and semiconductors has grown exponentially. We’re excited to use this award to further our material to meet the needs of existing and emerging industry partners and unlock a new era of computing,” HEXAspec co-founder Tianshu Zhai said in the release.

HEXAspec was founded by Zhai and Chen-Yang Lin, who both participated in the Rice Innovation Fellows program. A third co-founder, Jing Zhang, also worked as a postdoctoral researcher and a research scientist at Rice, according to HEXAspec's website.

The HEXASpec team won the Liu Idea Lab for Innovation and Entrepreneurship's H. Albert Napier Rice Launch Challenge in 2024. More recently, it also won this year's Energy Venture Day and Pitch Competition during CERAWeek in the TEX-E student track, taking home $25,000.

"The grant from the NSF is a game-changer, accelerating the path to market for this transformative technology," Kyle Judah, executive director of Lilie, added in the release.

3 Houston sustainability startups score prizes at Rice University pitch competition

seeing green

A group of Rice University student-founded companies shared $100,000 of cash prizes at an annual startup competition — and three of those winning companies are focused on sustainable solutions.

Liu Idea Lab for Innovation and Entrepreneurship's H. Albert Napier Rice Launch Challenge, hosted by Rice earlier this month, named its winners for 2024. HEXASpec, a company that's created a new material to improve heat management for the semiconductor industry, won the top prize and $50,000 cash.

Founded by Rice Ph.D. candidates Tianshu Zhai and Chen-Yang Lin, who are a part of Lilie’s 2024 Innovation Fellows program, HEXASpec is improving efficiency and sustainability within the semiconductor industry, which usually consumes millions of gallons of water used to cool data centers. According to Rice's news release, HEXASpec's "next-generation chip packaging offer 20 times higher thermal conductivity and improved protection performance, cooling the chips faster and reducing the operational surface temperature."

A few other sustainability-focused startups won prizes, too. CoFlux Purification, a company that has a technology that breaks down PFAS using a novel absorbent for chemical-free water, won second place and $25,000, as well as the Audience Choice Award, which came with an additional $2,000.

Solidec, a company that's working on a platform to produce chemicals from captured carbon, and HEXASpec won Outstanding Achievement in Climate Solutions Prizes, which came with $1,000.

The NRLC, open to Rice students, is Lilie's hallmark event. Last year's winner was fashion tech startup, Goldie.

“We are the home of everything entrepreneurship, innovation and research commercialization for the entire Rice student, faculty and alumni communities,” Kyle Judah, executive director at Lilie, says in a news release. “We’re a place for you to immerse yourself in a problem you care about, to experiment, to try and fail and keep trying and trying and trying again amongst a community of fellow rebels, coloring outside the lines of convention."

This year, the competition started with 100 student venture teams before being whittled down to the final five at the championship. The program is supported by Lilie’s mentor team, Frank Liu and the Liu Family Foundation, Rice Business, Rice’s Office of Innovation, and other donors

“The heart and soul of what we’re doing to really take it to the next level with entrepreneurship here at Rice is this fantastic team,” Peter Rodriguez, dean of Rice Business, adds. “And they’re doing an outstanding job every year, reaching further, bringing in more students. My understanding is we had more than 100 teams submit applications. It’s an extraordinarily high number. It tells you a lot about what we have at Rice and what this team has been cooking and making happen here at Rice for a long, long time.”

Houston startup strikes deal to develop hydrogen production plant in Canada

hydrogen partnership

Houston-based cleantech startup Vema Hydrogen has reached a tentative agreement with Canada-based CHARBONE Corp. to develop a hydrogen production and processing plant in Québec.

The deal would couple Vema’s production of engineered mineral hydrogen with CHARBONE’s purification, compression and distribution capabilities.

Engineered mineral hydrogen, also known as orange hydrogen, is produced underground by accelerating naturally occurring geochemical reactions in iron-rich rock formations, according to the journal Energy & Environmental Science.

“Across high-value markets — from aviation and maritime fuels to industrial gases — there is incredible demand for Vema’s low-carbon [hydrogen]. Now, more than ever, we need a pathway to deliver these low-carbon fuels,” Pierre Levin, CEO of Vema, said in a news release.

The project would enable Vema to expand into emerging markets like low-carbon maritime and aviation fuel, e-fuels and power generation. Incorporating CHARBONE’s capabilities, the agreement would also support Québec’s hydrogen supply chain.

“The market is demanding high-value industrial gases, and our customers need cleaner, more reliable supply. By pairing Vema’s [hydrogen] feedstock with our purification and distribution capabilities, we’re strengthening Québec’s position as a regional hub for next-generation hydrogen,” Dave Gagnon, CEO of CHARBONE, added in the release.

Vema said in February that it had completed drilling of its first two pilot wells in Québec, making them the world’s first pilot well for orange hydrogen. It’s the first time Vema’s technology has been used outside a lab.

“This pilot will provide the critical data needed to validate [our hydrogen] at commercial scale and demonstrate that Quebec can lead the world in this emerging clean energy category,” Levin said. “The quality of the rock within our core samples is exactly what we expected and is very promising for hydrogen yields.”

Shortly before Vema carried out the pilot drilling, it signed a 10-year deal with California-based energy technology company Verne Power to supply clean hydrogen for California data centers. Over the course of the 10-year agreement, Vema will boost annual production of orange hydrogen to more than 36,000 metric tons.

“There is a robust market for baseload power generation across the U.S., where data centers are straining the grid,” Levin said. “As we power California’s fastest-growing markets with clean hydrogen, we look toward expanding our hydrogen to markets globally and supporting AI-driven power hubs.”

Vema, founded two years ago, raised $13 million in seed funding in 2025.

“The energy transition and emerging uses of hydrogen have spurred demand for clean hydrogen,” Levin said in its funding announcement. “However, existing decarbonized hydrogen production methods simply don’t work — they are too costly and energy-intensive. Vema is here to change that. It’s time to unlock a new era of scalable, low-carbon hydrogen.”
