Three Houston energy startups are in the running for the $100,000 cash prize in Cleantech.org's GS Beyond Energy Innovation Challenge.

Amperon Holdings, Cemvita Factory, and Veloce Energy are among the competition's 24 semifinalists, which were announced June 17. Five semifinalists will be chosen to pitch their concepts during a virtual event July 21, and then the winner of the $100,000 prize will be named.

"This is not like the cleantech sector was 10 years ago. Getting down to 24 [semifinalists] was hard. Getting down to five finalists will be extremely challenging," Neal Dikeman, chairman and founder of Cleantech.org and a partner at one of the prize sponsors, Houston-based Energy Transition Ventures, says in a news release.

Amperon, with an office in Houston and headquarters in New York City, is a semifinalist in the "digitization of energy" category. The company, founded in 2017, builds real-time electricity demand tools for utilities, energy retailers, grid operators, and institutional traders. So far, Amperon has raised $4.3 million in funding, according to Crunchbase.

Houston-based Cemvita, founded in 2017 by siblings Tara and Moji Karimi, is a semifinalist in the "new fuels" category. Its biotechnology transforms carbon dioxide emissions into sustainable chemicals and polymers. In a recent interview for the Houston Innovators Podcast, Moji Karimi explained how unprecedented his work is — and how ready for collaboration his team is.

"There weren't biotech companies working with oil and gas companies for this use case that we have now," Karimi says. "We're defining this new category for application of synthetic biology in heavy industries for decarbonization."

Veloce, with an office in Houston and headquarters in Los Angeles, is a semifinalist in the "e-mobility in cities" category. The company, founded in 2020, aims to make installation of electric vehicle charging stations cheaper and faster. Veloce is an inaugural member of Greentown Houston, an incubator for climate technology startups.

New-to-Houston cleantech incubator names inaugural members

to the lab

A Somerville, Massachusetts-based cleantech accelerator has announced the 16 startups that will be a part of its new Houston incubator program.

Greentown Labs named the companies in the cohort this week just a few weeks after announcing the location of its new lab and workspace. The 40,000-square-foot space is being renovated from a former grocery store and is expected to open next spring.

"These early-access members are innovating across the key greenhouse gas-emitting sectors—including electricity, manufacturing, buildings, and more—and their solutions are helping create a sustainable future for all," reads a blog post on the company's website.

Here are Greentown Houston's inaugural members:

  • Austin-based Applied Bioplastics is creating affordable plastic alternatives with plant matter to help reduce consumers' carbon footprint.

  • ClearValue uses pure hydrogen and oxygen as a sustainable power system.
  • e^2: equitable energy is described as a "multi-brand cause-marketing platform" that connects consumers to sustainable energy solutions through promotion and incentivization.
  • Eclipse Solar Projects builds, owns, and operates solar projects across the country through new technology and battery storage operations.
  • Houston-based Ennuity Holdings allows users to have access to solar energy subscription service — even though they don't have access to installing panels themselves.
  • Excipicio Energy , based in Houston, is taking renewable energy offshore by integrating wind, wave, and more into a single floating platform.
  • Houston-based Quantum New Energy platform, EnerWisely, helps people and companies make smart energy choices "to maximize their monetary savings and reduce their environmental impacts."
  • Spring, Texas-based Renu Energy is creating sustainable change through waste recycling and community engagement, according to its website.
  • REVOLUTION Turbine Technologies, based in North Carolina, is working on a power generator that can be used in the offshore setting.
  • Houston-based Revterra is developing a long-duration energy storage solution.
  • Skylark, based in Houston, created a "broadband last-mile radio systems for internet service providers, with a focus on 40 million unserved Americans in rural markets."
  • Austin-based swytchX is working on a cloud-based SaaS solution that uses blockchain technology to optimize renewable energy delivery.

NASA names new chief astronaut based in Houston

new hire

NASA has a new chief astronaut. Scott Tingle, stationed at the space agency’s Johnson Space Center in Houston, assumed the post Nov. 10.

Tingle succeeds NASA astronaut Joe Acaba, who had been chief astronaut since February 2023. Acaba now works on the staff of the Johnson Space Center’s director.

As chief astronaut, Tingle runs NASA’s Astronaut Office. His job includes developing astronauts’ flight crew operations and assigning crews for space missions, such as Artemis missions to the moon.

Tingle, a former captain in the Navy, was named a NASA astronaut candidate in 2009. He has logged over 4,500 flight hours in more than 50 aircraft.

Tingle was a flight engineer aboard the International Space Station, where he spent 168 days in orbit during two expeditions that launched in December 2017. Since returning to Earth, he has held various roles in the Astronaut Office, including mission support, technical leadership and crew readiness.

Before joining NASA, Tingle worked in El Segundo, California, on the technical staff of The Aerospace Corp., a nonprofit that supports U.S. space programs.

Tingle recalls expressing his desire to be an astronaut when he was 10 years old. It took him four tries to be accepted by NASA as an astronaut candidate.

“The first time I figured it was kind of too early. The second application, they sent out some feelers, and that was about it. Put in my third application, and got a couple of calls, but it didn’t quite happen,” Tingle said in an article published on the website of Purdue University, his alma mater.

ExxonMobil officially pauses plans for $7B Baytown hydrogen plant

Change of Plans

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

“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 created a new 10-year incentive, the 45V tax credit, for production of clean hydrogen. But under President Trump’s "One Big Beautiful Bill Act," the window for starting construction of low-carbon hydrogen projects that qualify for the tax credit has narrowed. The Inflation Reduction Act mandated that construction start by 2033. But the Big Beautiful Bill switched 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,” ExxonMobil Chairman and CEO Darren Woods said during the company’s second-quarter 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 said.

“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 has said the plant is slated to go online in 2027 and 2028.

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.
