“Houston Energy and Climate Startup Week was created to answer a fundamental question: Can we achieve more by working together than we can alone?” Jane Stricker, senior vice president at the Greater Houston Partnership and executive director of HETI, said in the release.

So far, events for the 2025 Houston Energy and Climate Startup Week include an introduction to climatetech accelerator Activate's latest cohort, the Rice Alliance Energy Tech Venture Forum, a showcase from Greentown Labs' ACCEL cohort, and Halliburton Labs Pitch Day.

Houston organizations New Climate Ventures and Digital Wildcatters, along with Global Corporate Venturing, are slated to offer programming again in 2025. And new partners, Avatar Innovations and Decarbonization Partners, are slated to introduce events. Find a full schedule here.

Other organizations can begin entering calendar submissions starting in May, according to the release.

Last year, Houston Energy and Climate Startup Week welcomed more than 2,000 attendees, investors and industry leaders to more than 30 events. It featured more than 100 speakers and showcased more than 125 startups.

"In 2024, we set out to build something with lasting impact—rooted in the ingenuity of Houston’s technologists and founders. Thanks to a collaborative effort across industry, academia, and startups, we’ve only just begun to showcase Houston’s strengths and invite others to be part of this movement," Stricker added in the release. "We can’t wait to see the city rise to the occasion again in 2025.”

How this 78-year-old Houston chemical company is evolving as an energy tech leader

“When we were founded, we were a chemical company. Today, we have morphed into a technology company,” says Kendra Lee, CEO of Merichem. Photo via LinkedIn

Kendra Lee had no designs on running the family business.

“In fact, I never planned on being a part of Merichem,” Lee recalls.

In 1945, Lee’s grandfather, John T. Files, and a pair of business partners founded the company in Houston. Their goal was to take a potential waste product and turn it into something that would benefit the oil and gas industry — an early attempt at sustainability.

What started as a soap and industrial cleaning company began procuring cresylate, which is a waste from the refineries treating gasoline, to recover spent cresylic acids, which are highly caustic, and refine them so they could be sold into the industrial chemicals market. Read more.

Rice Alliance calls for participants for its annual energy conference

now's the time to apply

This year marks the 20th anniversary of Energy Tech Venture Day, a one-day symposium for energy innovation put on by the Rice Alliance for Technology and Entrepreneurship. The organization is currently calling for applications for startups interested in participating.

The event is taking place on September 21 at Rice University and will bring together energy innovators, investors, corporate leaders, and the rest of the energy ecosystem. The programming will include panels and discussions as well as startup pitches from the Rice Alliance's Clean Energy Accelerator 2023 cohort.

In addition to the CEA pitches, energy tech startups from around the world can apply to be a part of the day and be in the running to be recognized as a select group as the "most-promising" at the conclusion of the pitches. Applications can be filled out online and are due July 14. Registration is also open online.

According to Rice, 90 or so companies will be selected to participate in one-on-one meetings with around 75 investors. The organization conducts a unique matchmaking round that pairs up investors and founders for four to 10 of these office hour meetings which will take place the day before the main event.

On the day of the Energy Tech Venture Day, around 40 companies will pitch to the rest of the crowd. At the end of the day and based off the investor feedback from the one-on-one meetings, 10 energy tech startups will be deemed the most-promising businesses and be presented with awards.

Last year, over a third of the companies that pitched were based in the Houston area. Two Houston-based companies received awards at the end of the day, including:

Kanin Energy, which works with heavy Industry to turn their waste heat into a clean baseload power source. The platform also provides tools such as project development, financing, and operations.
Syzygy Plasmonics, which is commercializing its light-reacting energy, which would greatly reduce carbon emissions in the chemical industry. The technology originated out of Rice University.

Houston companies win big at Elon Musk-backed carbon removal competition

xprize winners

Houston-based Mati Carbon has won the $50 million grand prize in the XPRIZE Carbon Removal competition, backed by Elon Musk’s charitable organization, The Musk Foundation.

Mati was selected in 2024 as one of 20 global finalists. The company removes carbon through its Enhanced Rock Weathering (ERW) program that works with agricultural farms in Africa and India.

The 3-year-old startup accelerates the natural process of rock weathering (ERW) by applying pulverized basalt to croplands of partnered smallholder farmers, free of charge. Mati says the farmers it partners with are some of the most vulnerable to the impacts of climate change.

“Winning this XPRIZE competition is an incredible honor and a definitive validation of our research and development, and building out the infrastructure needed to impact millions of farmers while delivering verifiable carbon dioxide removal at a gigaton scale,” Mati Carbon Founder and CEO Shantanu Agarwal, said in a news release. “I couldn’t be prouder, not just of the Mati team, but of our collaborators, research partners and the thousands of smallholder farmers who let us be part of their lives. This XPRIZE recognition will allow us to collaborate with local partners to accelerate the use of enhanced rock weathering across the Global South.”

Mati reports that it plans to use the award to “scale its efforts working with smallholder farmers worldwide.” Apart from the XPRIZE funding, Mati plans to grow its model through the sale of CDR credits. According to the company, it counts Shopify, Stripe, and H&M among its early carbon credit buyers.

“Mati Carbon’s deployments bolster farmers’ livelihoods through improved soil health, reduced agricultural inputs, and increased income at zero cost to them. Mati Carbon’s team has developed a scientifically rigorous approach to monitoring and verification, and excelled across each of XPRIZE’s prize evaluation criteria – operational, sustainability, and cost metrics – giving the XPRIZE judges the highest confidence in Mati Carbon’s solution’s long-term scalability,” the XPRIZE judges wrote.

Houston-based Vaulted Deep took home the second-runner-up prize in the competition and $8 million for its organic waste storage process. The company provides permanent carbon storage by injecting nonhazardous organic waste deep underground. It spun off with $8 million in seed funding from Advantek Waste Management Services in 2023.

"Our approach is grounded in geomechanical injection techniques that have been safely deployed globally for decades by our team and predecessors," Omar Abou-Sayed, co-founder and executive chairman of Vaulted, said in a separate release. "XPRIZE recognized that this is a proven approach—already in use, delivering impact, and built on the kind of reliability the industry needs to scale responsibly."

Launched in 2021, the four-year XPRIZE Carbon Removal competition challenged global innovators to deploy scalable solutions for removing carbon dioxide from the atmosphere and oceans. More than 1,300 teams from 88 countries competed. XPRIZE finalists were required to remove at least 1,000 tonnes of CO2 over a one-year demonstration period.

French company NetZero took home the first-runner-up prize of $15 million, and London-based UNDO came in as third-runner-up with a $5 million prize.

Since the announcement of the XPRIZE Carbon Removal competition, the Musk-led Department of Government Efficiency has cut climate funding for agencies, projects and research. While the Musk Foundation sponsored the XPRIZE event, it is not affiliated with the California-based organization, according to the Associated Press.
