Editor's note — This story has been updated and republished to reflect the new dates and details of Houston Climate Week.

The city of Houston is kicking off its rescheduled Houston Climate Week after the original week was postponed by threats of Hurricane Laura. The week-long virtual program supports Mayor Sylvester Turner's Climate Action Plan, which launched in April in response to Hurricane Harvey and other recent major climate events.

"We recognized how we just couldn't continue to do things as we had done them in the past — Harvey was a game changer," Turner says at the opening conversation of Houston Climate Week. "It set us up for enacting the city's first Climate Action Plan."

Every day between Monday, September 14, to Friday, September 18, the city will host two to three virtual events. For the full schedule, click here. Below are the can't-miss events on the agenda.

Overheard: Experts call for Houston to become the 'energy transition capital of the world'

eavesdropping online

Before the inaugural Houston Climate Week was shutdown — ironically by a major climate event — event attendees heard from a panel of energy experts that spoke of certain challenges the city's economy faces as the energy transition continues.

One of the last events of the programmed week that took place ahead of cancelations due to the threat of Hurricane Laura, was a virtual panel entitled, ENERGY TRANSITION: Making Houston a Global Leader in Energy Innovation. The conversation centered around what Houston is currently doing — and what it still needs to focus on — when it comes to the need to prioritize sustainability in oil and gas and new green alternatives in the greater energy industry.

Here are some of the highlights from the discussion.

“Houston has a spirit of innovation and entrepreneurship. We’ve all heard Houston be called the oil and gas capital of the world, but we’re the energy capital of the world — and we have the opportunity right now to become the energy transition capital of the world. We see that here — we want to be a part of that.”

— Kelsey Hultberg, vice president and chief of staff of Sunnova, a Houston-based residential solar energy company that went public last year.

“When you think about energy 2.0, it’s about what the energy industry look like in the future. In Houston, we are working hard to present ourselves not just as a current global energy leader, but the future energy leader of the world."

— Jose Beceiro, senior director of Energy 2.0 at the Greater Houston Partnership.

"The energy capital of the world has to be engaged and become the energy transition capital of the world."

— Juliana Garaizar, launch director of Greentown Labs - Houston.

“One of the thing we’re really focused on is energy resiliency and reliability. … After Hurricanes Harvey, Irma, and Maria, really fundamentally as an organization as that there is a need for energy reliability.”

— Hultberg says, adding that around a third of the company's solar sales include a battery.

"The oil and gas industry knows it is going to have to hire a whole new workforce going forward that’s much more technical in terms of data analytics, cloud computing, and edge computing. One method you’re seeing these companies try is investing in new types of energy resources. … Another method you’re seeing is these companies forming closer alliances in the tech industry.”

— Beceiro says, adding that these tech companies — like Amazon and Google — have zoomed in on Houston and increased their local presence.

“I really believe that innovation happens at the intersection of things and for that you really need a convening space for that.”

— Garaizar says, adding that she hopes Greentown Labs can help provide this convening space.

Rice University breaks ground on new innovation hub, The Arc

breaking ground

Construction is officially underway on Rice University's The Arc in Houston’s Ion District.

The university broke ground on the 200,000-square-foot research, corporate innovation and office building on Nov. 4. The facility will share a plaza with the existing Ion building, fostering collaboration within the innovation space, according to Rice.

“The Arc will bring Rice’s extraordinary research and talent and Houston’s impactful innovation ecosystem into even closer connection with the industries and innovators working to solve some of the world’s most consequential challenges,” Rice President Reginald DesRoches said in an announcement. “That constant exchange of ideas and expertise will help move discoveries more rapidly from the laboratory to real-world impact.”

Construction is scheduled to be completed by Q2 2028. Rice Real Estate Co. is developing the project, and Rice University will occupy about 80,000 square feet in the building (about 40 percent). Preleasing has begun, with floor plans ranging from 28,000 to 31,000 square feet.

The Arc will feature conference and meeting spaces, an amenity lounge, fitness center, outdoor plazas, underground parking, and on-site retail and dining, according to the release.

It aims to host tenants focused on artificial intelligence and machine learning, data science, robotics, quantum science and engineering and energy, including Rice's new AI Foundry.

Rice says the AI Foundry will be a space where university experts and partners can support organizations with AI challenges. Rice recently committed to hiring 75 new AI-focused faculty and announced plans to launch a new Master of Artificial Intelligence (MAI) next fall.

“The AI Foundry is exactly the kind of collaboration the Arc is designed to enable,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs at Rice, added in the release. “By bringing Rice researchers together with industry partners in a shared environment, we can accelerate the movement of ideas from research into practical applications while helping organizations build the capabilities they need to succeed as AI continues to evolve.

Developers of The Arc are targeting LEED Gold certification by incorporating smart building automation and energy-saving features into the project's design. Rice first announced the project in September 2025.

As part of the 2026 Houston Innovation Awards, our Scaleup of the Year category honors innovative later-stage startups that have recently reached a significant milestone in company growth. Three scaleups have been named finalists for the 2026 award.

Read more about these businesses, their founders and their breakthrough technologies below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Erock

Energy infrastructure company Erock, previously known as Enchanted Rock, develops dual-purpose microgrids that rely on natural gas and renewable natural gas to produce lower carbon emissions and air pollutants than diesel generators. Its products can provide bridge power before grid interconnection, backup power during outages and dispatchable capacity that supports long-term grid reliability. The company has more than 1,100 megawatts of installed capacity and over 20 years of experience serving commercial, municipal and large-scale technology customers.

Erock completed its initial public offering this year, raising approximately $600 million in gross proceeds. It also grew its contracted power system sales backlog to approximately $1.7 billion, up tenfold year-over-year, with production sold out through 2028, according to the company's application. The company secured a major equipment order from Anthropic, began construction of the 366-megawatt El Paso Electric project supporting Meta's data center campus, and started assembly operations at its Hyperion facility in Cypress, Texas.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A this month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Venus Aerospace

Spacetech company Venus Aerospace is developing a high-thrust rotating detonation rocket engine (RDRE) that replaces the subsonic combustion used in conventional rocket engines. The RDRE is a compact, simpler engine that can deliver up to 15 percent greater efficiency for defense and space applications. It completed its first U.S. flight test of the engine last summer.

Venus Aerospace was founded in 2020 by CEO Cassie Duggleby and CTO Andrew Duggleby. It raised a $20 million Series A in 2022 and $42 million Series A2 in 2025. It closed a $91 million Series B earlier this year and expanded its leadership team. The company is working toward longer-duration and higher-thrust testing and advancing its flight program.
