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.

Houston university to launch artificial intelligence major, one of first in nation

BS in AI

Rice University announced this month that it plans to introduce a Bachelor of Science in AI in the fall 2025 semester.

The new degree program will be part of the university's department of computer science in the George R. Brown School of Engineering and Computing and is one of only a few like it in the country. It aims to focus on "responsible and interdisciplinary approaches to AI," according to a news release from the university.

“We are in a moment of rapid transformation driven by AI, and Rice is committed to preparing students not just to participate in that future but to shape it responsibly,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs, said in the release. “This new major builds on our strengths in computing and education and is a vital part of our broader vision to lead in ethical AI and deliver real-world solutions across health, sustainability and resilient communities.”

John Greiner, an assistant teaching professor of computer science in Rice's online Master of Computer Science program, will serve as the new program's director. Vicente Ordóñez-Román, an associate professor of computer science, was also instrumental in developing and approving the new major.

Until now, Rice students could study AI through elective courses and an advanced degree. The new bachelor's degree program opens up deeper learning opportunities to undergrads by blending traditional engineering and math requirements with other courses on ethics and philosophy as they relate to AI.

“With the major, we’re really setting out a curriculum that makes sense as a whole,” Greiner said in the release. “We are not simply taking a collection of courses that have been created already and putting a new wrapper around them. We’re actually creating a brand new curriculum. Most of the required courses are brand new courses designed for this major.”

Students in the program will also benefit from resources through Rice’s growing AI ecosystem, like the Ken Kennedy Institute, which focuses on AI solutions and ethical AI. The university also opened its new AI-focused "innovation factory," Rice Nexus, earlier this year.

“We have been building expertise in artificial intelligence,” Ordóñez-Román added in the release. “There are people working here on natural language processing, information retrieval systems for machine learning, more theoretical machine learning, quantum machine learning. We have a lot of expertise in these areas, and I think we’re trying to leverage that strength we’re building.”
