comeback tour

Six local organizations focused on the energy transition have teamed up to bring back Houston Energy and Climate Startup Week.

The second annual event will take place Sept. 15-19, according to an announcement. The Ion District will host many of the week's events.

Houston Energy and Climate Startup Week was founded in 2024 by Rice Alliance for Technology and Entrepreneurship, Halliburton Labs, Greentown Labs, Houston Energy Transition Initiative (HETI), Digital Wildcatters and Activate.

“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.”

The Ion in Midtown has some new tenants taking up residence in its 90 percent-leased building.

Occidental Petroleum Corporation, Fathom Fund, and Activate are the latest additions to the Ion, according to a news release from Rice University and the Rice Real Estate Company, which own and operate the 16-acre Ion District where the Ion is located. With the additions, the building has just 10 percent left up for grabs.

“As the Ion continues to attract leading companies and organizations across industries, it’s clear that our vision of creating a dynamic and collaborative environment for innovation is resonating,” Ken Jett, president of the Rice Real Estate Company and vice president of facilities and capital planning at Rice, says in the release. “We are proud to set the standard for how the workplace can evolve to foster the commercialization and growth of transformative technologies that enhance quality of life in our community and beyond.”

Oxy, which was named a corporate partner of the Ion last year, now has nearly 6,500 square feet on the fourth floor. The build out process is slated to be completed by early 2025.

While Oxy represents the corporate side of innovation, the other two additions have their own roles in the innovation arena. Houston-based Fathom Fund, which launched its $100 million fund earlier this year, is targeting deep-tech venture opportunities and is led by Managing Partners Paul Sheng and Eric Bielke.

Founded in Berkeley, California, Activate, which announced its expansion into Houston in 2023, has officially named its local office in the Ion. The hardtech-focused incubator program recently named its inaugural cohort and opened applications for the 2025 program.

Other recent joiners to the Ion includes Kongsberg Digital, Artemis Energy Partners, CES Renewables, and Eleox.

“The partnerships we’ve forged are vital to shaping the Ion into a vibrant ecosystem for startups, where collaborative innovation is not only driving local economic growth but also positioning Houston as a global leader in the energy transition,” Paul Cherukuri, chief innovation officer at Rice University, says. “With our team leading the programming and activation across the Ion district, we are creating companies that harness cutting-edge technology for the benefit of society—advancing solutions that contribute to social good while addressing the most pressing challenges of our time. This powerful network is redefining Houston’s role in the future of energy, technology, and social impact.”

Hardtech innovator fellowship opens applications for 2025 Houston cohort

submit now

Applications are officially open for a hardtech-focused incubation and fellowship program's second Houston cohort.

Activate's application is live from now through October 23, and all founders of early-stage, research-backed hardtech companies in Houston are encouraged to apply. The Berkley, California-based program launched in Houston last year and recently named its inaugural Houston cohort.

“The Activate Fellowship provides an opportunity for approximately 50 scientists and engineers annually to transform into entrepreneurial leaders, derisk their technologies, define first markets, build teams, and secure follow-on funding,” says Activate’s executive managing director, Aimee Rose, in a news release. “With an average 30 percent annual growth in applications since 2015, we know there is high demand for what we do, and we’re excited to see the talent and impactful ideas that come through the pipeline this year.

The program, led locally by Houston Managing Director Jeremy Pitts, has 249 current Activate fellows and alumni that have collectively raised over $2.4 billion in public and private funding since the organization was founded in 2015.

“The success of Activate Fellows is ample evidence that scientists and engineers have the talent and drive to face global challenges head-on,” adds Activate chief fellowship officer, Brenna Teigler. “Our diverse fellows are transforming technical breakthroughs into businesses across the United States in 26 states across a range of sectors spanning carbon management, semiconductors, manufacturing, energy, chemicals, ocean tech, and more.”

The application is available online, and fellows will be selected in April of next year. The 2025 program will begin in June.

Activate is looking for local and regional early-stage founders — who have raised less than $2 million in funding — who are working on high-impact technology. Each cohort consists of 10 fellows that join the program for two years. The fellows receive a living stipend, connections from Activate's robust network of mentors, and access to a curriculum specific to the program.

Houston-based ENGIE wins national award for clean energy leadership

top honor

Houston-based ENGIE has been recognized for its work in the clean energy space.

The battery storage and energy infrastructure company recently won the 2026 Green Power Leadership Award in the Market Innovation category for its work advancing 24/7 renewable energy solutions. The awards honor individuals and companies advancing sustainability and renewables in the energy industry through innovation and leadership.

The Center for Resource Solutions (CRS), a San Francisco-based environmental nonprofit, grants the awards each year during the Renewable Energy Markets conference. Past recipients include companies like Microsoft, Salesforce and Google. Other award categories include Education & Awareness, Impactful Procurement and Leader of the Year.

"This recognition reflects ENGIE's commitment to developing innovative solutions that give customers greater transparency, accountability and confidence in their sustainability strategies," Anne-Laure Chassanite, interim CEO of ENGIE North America and CEO of ENGIE Resources, said in a news release.

Specifically, the honor recognizes ENGIE's Energy+ 24/7 solution, which helps customers better understand the impact of their energy consumption while also pushing sustainability efforts. ENGIE assists organizations and the public in gaining insight into renewable energy and hourly electricity consumption to see where clean energy is being utilized most effectively.

"As the market continues to evolve, we believe the future of renewable energy procurement lies in helping organizations better understand the impact of their electricity consumption and make more informed energy decisions,” Chassanite added in the release.” Our 24/7 offering is helping establish a new standard by combining innovation with practical, scalable solutions that support meaningful progress toward sustainability goals."

ENGIE's US Energy+ team was also recognized for its customer-focused renewable energy solutions.

"This achievement is the result of the dedication and innovation of teams across ENGIE who are continually challenging what's possible in the energy transition," Chassanite also said in the release.

In June, ENGIE’s 24/7 signed an agreement with Aker BioMarine to supply Texas-sourced clean energy to the Norwegian company's Houston manufacturing site.

ExxonMobil secures approval for $5B East Texas carbon capture project

ccs expansion

Spring-based ExxonMobil has won approval from the Texas Railroad Commission for a $5 billion carbon capture and storage project in East Texas.

Dominic Genetti, senior vice president of CCS at ExxonMobil, told The Financial Times, which broke the news, that the Railroad Commission’s action is a “major milestone” that lets the company keep expanding along the Gulf Coast. In a 2-1 vote, commissioners authorized a carbon sequestration permit for the project.

“The Railroad Commission clearly recognizes the important role carbon capture and storage can play in meeting growing global demand for lower-carbon products while supporting new jobs and economic growth,” Genetti said.

The U.S. Environmental Protection Agency (EPA) approved ExxonMobil’s Rose CCS project last year.

The project will enable the company to inject about 53 metric tons of industrial customers’ carbon emissions into three underground wells it drilled in the Beaumont-Port Arthur area. Over a 13-year period, ExxonMobil plans to inject about 4 million metric tons per year into the Fleming and Upper Frio rock formations, according to Carbon Herald.

ExxonMobil says it owns the world’s first and largest CCS system, comprising 1,300 miles of CO2 pipeline and secure storage sites. Seventy percent of the pipelines are along the Gulf Coast.

The company ramped up its CCS business in 2023 with the $4.9 billion purchase of Denbury, which owned about 1,000 miles of CO2 pipelines.

“Our expertise, combined with Denbury’s talent and CO2 pipeline network, expands our low-carbon leadership and best positions us to meet the decarbonization needs of industrial customers while also reducing emissions in our own operations,” ExxonMobil Chairman and CEO Darren Woods said when the deal closed.

In January, Genetti wrote in a post on ExxonMobil’s website that the company is committed to CCS “for the long haul.”

“CCS is not new technology, but it’s flown relatively under the radar compared with the attention that production of hydrocarbons commands,” he wrote. “Now, as the world becomes more aware of the need to reduce emissions, CCS finally has a brighter spotlight and a broader runway to scale up.”

The company also announced this week that it has begun CCS operations at a direct reduced iron facility in Convent, Louisiana. The project will capture, transport and store up to 800,000 metric tons of CO2 per year, according to the company.
