A clean energy program has announced its third cohort and named the 15 startups that were accepted into to the accelerator.

The Rice Alliance's Clean Energy Accelerator revealed its 2023 cohort that will be in the 10-week program that kicks of July 25. CEA, a hybrid program based out of the Ion, will wrap up with a Demo Day alongside the 20th Annual Rice Alliance Energy Tech Venture Forum on September 21.

The accelerator, led by Kerri Smith and Matt Peña, provides the cohort with programming, networking, and mentorship from six executives in residence — Nathan Ball, Fatimah Bello, Michael Egan, Michael Evans, Stephen Sims, and Deanna Zhang.

Since the Clean Energy Accelerator launched in 2021, the program has supported 29 ventures that have gone on to raise over $75 million in funding, identified and launched pilots, and created jobs, According to Rice, many of these companies relocated to Houston.

Class 3, which has already raised $23.3 million in funding, hails from four countries and seven states and are addressing a range of energy solutions — from advanced materials, carbon management/capture, energy storage, hydrogen, solar energy, wind energy, and more. They were selected by a screening committee consisting of more than 50 industry experts, investors, energy leaders, and entrepreneurs.

The third class, as announced by Rice Alliance, is as follows:

  • Ayrton Energy, based in Alberta, Canada, provides hydrogen storage technology that improves hydrogen transport logistics for distributed energy applications.
  • Headquartered in Massachusetts, Carbix transforms atmospheric carbon dioxide emissions into building materials using proprietary reactor technology.
  • Houston-based CryoDesalination lowers the carbon footprint and cost of removing salts and heavy metals from water and industrial effluents.
  • Digital Carbon Bank, based in Alberta, Canada, provides a carbon solution tailored for the energy industry.
  • Chandler, Arizona-based EarthEn provides compressed carbon dioxide-based energy storage and artificial intelligence solutions allowing grid owners/operators to be completely renewable.
  • H Quest Vanguard, from Pittsburgh, provides green hydrogen at a five to 10 times lower cost to users of natural gas to decarbonize industrial heat.
  • Calgary, Alberta-based Highwood Emissions Management's SaaS platform allows oil and gas companies to understand their emissions and develop robust plans to reduce them.
  • Icarus RT, from San Diego, California, improves photovoltaic efficiency while enabling useful heat energy storage.
  • Los Altos, California-based Khepra has developed a chemical manufacturing platform for the low-cost, sustainable production of agrochemicals.
  • Binghamton, New York-based Natrion’s electrolyte is a drop-in solid-state battery component that can be rapidly implemented into existing batteries.
  • Oceanways, based in London, provides low-cost, flexible and scalable zero-emission underwater "virtual pipelines" to energy producers.
  • Relyion Energy, from Santa Clara, California, is developing battery usage and intelligence solutions with deeper data and insights for retired electric vehicle batteries.
  • Massachusetts-based Triton Anchor provides a more cost-effective anchoring solution for offshore clean energy with minimal environmental impact.
  • TROES, from Markham, Ontario, provides a 4-in-1 microgrid solution with integrated hardware and software for a streamlined energy storage experience.
  • Mexico City-based Tycho Solutions supports clean energy project developers by saving time and money during the critical project-siting process.

Houston company partners on AI-powered medical support for space missions

AI in space

Houston-based Aexa Aerospace has partnered with SpacePort Australia (SPA) to build medical AI solutions for space crews.

Known as The Hamilton Project, the collaboration aims to complete the training and refinement of a “deductive medical AI model” designed to aid and treat astronauts and space travellers. With limited to no real-time access to doctors on Earth during space missions, the project's goal is to create an AI model that would serve as a medical resource.

“‘The Hamilton Project’ is a sophisticated AI model, integrating academic and clinical knowledge in a unique way,” Aexa founder and CEO Feranando De La Peña Llaca said in a news release. “It is paving the way for future autonomous attending.”

The project is named after NASA flight surgeon Dr. Douglas Hamilton, who participated in 50 missions.

SPA, an independent research organization, will bring its practical medical knowledge and clinical experience to The Hamilton Project, which builds on Australia’s rural and remote medical training programs. SPA founder Dr. Gabrielle Caswell brings 20 years of remote medicine experience that SPA believes will help address the issues that could be encountered in space.

“Rural general practitioners in Australia practice ‘pre-cradle to grave’ medicine, including areas considered sub-specialities in most western countries: OBYN, paediatrics, trauma management, anaesthetics, general surgery, mental health and geriatrics,” Caswell added in the release. “This broad clinical skill set encompasses all stages and phases of human life. And importantly practitioners are also trained in the management of severe trauma. "It is anticipated that doctors and medical staff will become embedded into missions, and all these skills will be required over time, to create successful space economic zones.”

Aexa Aerospace’s previous work includes developing holographic medical devices that have been trialled on the International Space Station. Read more here.

Houston residents rank economy as biggest problem, new Kinder survey shows

by the numbers

The region’s economy tops the list of concerns of Houston-area residents surveyed by Rice University’s Kinder Institute for Urban Research.

Respondents in the Kinder Houston Area Survey, which questioned nearly 9,000 residents of Harris, Fort Bend and Montgomery counties, cite the regional economy as the area’s “biggest problem.”

Shrinking confidence in job opportunities and growing household financial pressures fueled the grim economic outlook:

  • The share of residents rating job prospects as “good” or “excellent” fell by more than 25 percentage points, the sharpest single-year decline since the 1980s.
  • Seventy-nine percent of those earning less than $25,000 said they’d be unable to cover an unplanned $400 expense. That was up from 72 percent last year. In the $50,000-to-$99,999 category, the figure was 39 percent, up from 30 percent last year.
  • More than 20 percent of residents said their financial status was worse than it was 12 months earlier.

“These challenges were particularly notable among lower- and middle-earning households,” according to a report about the survey.

Dan Potter, co-director of the institute’s Houston Population Research Center, says the annual survey “provides community leaders and the public with a map of where we’ve been on key issues, where we are now, and what’s of looming importance. It allows everyone to work together toward a better future for our city and our region.”

Houston-based Oxy officially announces CEO transition, names successor

Team Transition

Houston-based Occidental (Oxy) has officially announced its longtime CEO's retirement and her successor.

Oxy shared that Vicki Hollub will retire June 1. Reuters first reported Hollub's plan to retire in March, but a firm date had not been set. Hollub will remain on Oxy's board of directors.

Richard Jackson, who currently serves as Oxy's COO, will replace Hollub in the CEO role.

“It has been a privilege to lead Occidental and work alongside such a talented team for more than 40 years," Hollub shared in a news release. "Following the recently completed decade-long transformation of the company, we now have the best portfolio and the best technical expertise in Occidental’s history. With this strong foundation in place, a clear path forward and a leader like Richard, who has the experience and vision to elevate Occidental, now is the right time for this transition. “I look forward to supporting Richard and the Board through my continued role as a director.”

Hollub has held the top leadership position at Oxy since 2016 and has been with the energy giant for more than 40 years. Before being named CEO, she served as COO and senior executive vice president at the company. She led strategic acquisitions of Anadarko Petroleum in 2019 and CrownRock in 2024, and was the first woman selected to lead a major U.S. oil and gas company.

Hollub also played a key role in leading Oxy's future as a "carbon management company."

Jackson has been with Oxy since 2003. He has held numerous leadership positions, including president of U.S. onshore oil and gas, president of low carbon integrated technologies, general manager of the Permian Delaware Basin and enhanced oil recovery oil and gas, vice president of investor relations, and vice president of drilling Americas.

He was instrumental in launching Oxy Low Carbon Ventures, which focuses DAC, carbon sequestration and low-carbon fuels through businesses like 1PointFive, TerraLithium and others, according to the company. He also serves on the Oil and Gas Climate Initiative’s Climate Investment Board and the American Petroleum Institute’s Upstream Committee. He holds a bachelor's degree in petroleum engineering from Texas A&M University.

Jackson was named COO of Oxy in October 2025. In his new role as CEO, he will also join the board of directors, effective June 1.

“I am grateful to be appointed President and CEO of Occidental and excited about the opportunity to execute from the strong position and capabilities that we built under Vicki’s leadership,” Jackson added in the release. “It means a lot to me personally to be a part of our Occidental team. I am committed to delivering value from our significant and high-quality resource base. We have a tremendous opportunity to focus on organic improvement and execution to deliver meaningful value for our employees, shareholders and partners.”
