cooler computing

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.

2 sustainability-focused student startups named to Houston accelerator

ready to grow

Rice University's Liu Idea Lab for Innovation & Entrepreneurship, or Lilie, has named eight teams to the second cohort of the Lilie Summer Venture Studio, and two have sustainability as a goal.

According to Rice, the 12-week program received a record number of applications, that spanned the campus' degree offerings.

“We are thrilled to see such a high level of interest and excitement from Rice students for a high-growth venture accelerator,” Kyle Judah, executive director of Lilie, said in a statement. “The diversity and creativity in this year's applications were truly inspiring, and we’re excited to support these promising ventures with the resources and mentorship they need to hit escape velocity and create the next generation of pillar companies for Houston, Texas and the world.”

The selected teams will receive $15,000 in non-dilutive funding from the accelerator, along with access to coworking space and personalized mentorship in the Liu Idea Lab.

Coflux Purification, a patent-pending in-stream module that breaks down PFAS using a novel absorbent for chemical-free water, was named to the cohort, as was Solidec, a technology platform that extracts molecules from water and air, transforms them into pure chemicals and fuels without any carbon emissions.

Here are the rest of the teams for the 2024 Lilie Summer Venture Studio:

  • Docflow, focused on streamlining residency shift scheduling
  • JewelVision, building virtual fitting rooms for jewelry e-commerce retailers using generative AI
  • Levytation, using data science and AI to answer critical questions about sales and customers for coffee shop management
  • OnGuard, a marketplace to book off-duty police officers and security professionals
  • Roster, leverages data on athletes in the NCAA Transfer Portal to automatically send updates on players to coaches
  • Veloci, a running shoe venture that addresses common pains through shoe design

Lilie launched the Summer Venture Studio last year. According to Rice, two out of the six teams selected, Helix Earth Technologies and Tierra Climate, which both also tackle sustainability challenges, raised venture capital funds after completing the accelerator program.

Helix Earth Technologies also went on to earn the inaugural TEX-E Prize at CERAWeek in 2023.

“The track record of our Summer Venture Studio Accelerator speaks for itself, despite being early in our second year," Taylor Anne Adams, head of venture acceleration programs at the Liu Idea Lab, said in a statement. "This is the power of entrepreneurship programming that is designed by founders, for founders, that happens at the Liu Idea Lab.”

Last year, Lilie also named 11 successful business leaders with ties to Houston to its first Lilie’s Leadership Council. Each agreed to donate time and money to the university’s entrepreneurship programs.

ExxonMobil pauses plans for $7B hydrogen plant in Baytown

project on pause

As anticipated, Spring-based oil and gas giant ExxonMobil has paused plans to build a low-hydrogen plant in Baytown, Chairman and CEO Darren Woods told Reuters.

“The suspension of the project, which had already experienced delays, reflects a wider slowdown in efforts by traditional oil and gas firms to transition to cleaner energy sources as many of the initiatives struggle to turn a profit,” Reuters reported.

Woods signaled during ExxonMobil’s second-quarter earnings call that the company was weighing whether it would move forward with the proposed $7 billion plant.

The Biden-era Inflation Reduction Act established a 10-year incentive, the 45V tax credit, for production of clean hydrogen. But under President Trump’s One Big Beautiful Bill Act, the period for beginning construction of low-carbon hydrogen projects that qualify for the tax credit has been compressed. The Inflation Reduction Act called for construction to begin by 2033. The Big Beautiful Bill changed the construction start time to early 2028.

“While our project can meet this timeline, we’re concerned about the development of a broader market, which is critical to transition from government incentives,” Woods said during the earnings call.

Woods had said ExxonMobil was figuring out whether a combination of the 45Q tax credit for carbon capture projects and the revised 45V tax credit would enable a broader market for low-carbon hydrogen.

“If we can’t see an eventual path to a market-driven business, we won’t move forward with the [Baytown] project,” Woods told Wall Street analysts.

“We knew that helping to establish a brand-new product and a brand-new market initially driven by government policy would not be easy or advance in a straight line,” he added.

ExxonMobil announced in 2022 that it would build the low-carbon hydrogen plant at its refining and petrochemical complex in Baytown. The company had indicated the plant would start initial production in 2027.

ExxonMobil had said the Baytown plant would produce up to 1 billion cubic feet of hydrogen per day made from natural gas, and capture and store more than 98 percent of the associated carbon dioxide. The plant would have been capable of storing as much as 10 million metric tons of CO2 per year.
