Three Houston energy tech innovators sought to quantify Houston's growth as an energy tech ecosystem, and, after 200 survey respondents and dozens of interviews, they've created six calls to action for the city.

Taylor Chapman, Gabe Malek, and Deanna Zhang created the Texas Climate Tech Collective to issue the Houston's Climate Tech Ecosystem 2023 report. The trio revealed some of its key takeaways at Greentown Houston's Climatetech Summit last month.

"We wanted to understand how the city has evolved," Malek, who's also chief of staff at Fervo Energy, said at the event. "We went into this project with a shared belief that Houston has unique characteristics that set it apart from the other cities thinking about climate, and if we could really lean into those characteristics, develop them, and amplify them, we could help grow the ecosystem in Houston and build climate solutions ... to accelerate the energy transition."

The full report, which is available online, highlighted six key takeaways paired with six action items.

1. "Houston has a perception problem."

Houston is known as a leader in the energy industry, which positions it well in a lot of ways, but in other ways, as Zhang points out, Houston might be being left out.

"People in this community like to talk about energy because we are the energy capital of the world, so we use a lot of energy-centric terms," she says, using "energy transition" as an example. "We don't use the word climate enough."

It might just be semantics, but it could be a reason the city isn't as regarded as a climatetech leader.

"If other ecosystems are using 'climate' and 'climatetech,' we need to be using these terms," she continues. "It's like SEO but for the ecosystem."

2. "Houston needs more risk capital, especially at the earlier stages." 

Money is a huge factor, which comes as no surprise. While the city has a lot of corporations and private equity here, as Zhang explains, there seems to be room for improvement for early-stage resources.

"If you're a founder raising pre-seed, seed, or even series A, often times you have to go outside of Houston to meet those investors," she says.

According to the report, about half of survey respondents chose "access to venture capital" as one of the biggest challenges facing the ecosystem.

3. "Houston’s startup scene has improved radically."

The report found that 80 percent of responders agreed to the statement: “the ecosystem has improved dramatically over the last 5 years.” Meanwhile, 75 percent of respondents agreed that “Houston is more innovative than outsiders perceive it to be."

So what's holding the city back? According to the collective, "Shameless self-promotion of ecosystem accomplishments."

"We need to be shouting from the rooftops what is happening in this city. It's really a PR game," Zhang says.

4. "Houston’s energy resources and infrastructure have massive potential to create change, but are underutilized by the climate ecosystem."

The collective and survey respondents acknowledge that Houston has a lot of infrastructure already in place, but the call to action is for coordination of these resources.

"Greentown, Ion, Halliburton Labs, HETI — the list goes on and on, but people don't know where to start," Chapman says.

The report says the city's resources are "woefully undertapped" and "29 percent of respondents highlighted partnerships, coordination of existing assets, and Houston’s own future investments in infrastructure as potential accelerants to growth."

5. "Houston’s strong workforce and human capital are one of its greatest strengths – and it should be investing in transitioning that workforce to new opportunities."

Cultivating the workforce for the energy transition needs to be a major priority, according to the collective. The city has a talented workforce for engineering, technical, and project management talent.

"How do we reach and transition this workforce?" Chapman asks. "It's a huge opportunity and critical for Houston to ensure that its economic development continues to grow."

6. "Houston knows how to build...but needs to put expertise that towards climate innovation."

Houston as a major, sprawling city needs to continue to become "greener" in every way. While Chapman praises the city has done with its Climate Action Plan, Houston still lags other major cities like Los Angeles and New York in this way, per the report. Fourteen percent of respondents cited better climate-friendly infrastructure as a priority issue.

Chapman urged the audience to get involved locally to move the needle on more green initiatives for the city.

UH report says CO2 technology could unlock 137B barrels of U.S. oil

oil recovery

A new report from the University of Houston estimates that a method known as carbon dioxide-enhanced oil recovery (CO2-EOR) could recover roughly 137 billion barrels of U.S. oil—with Texas and the Gulf Coast poised to play a major role.

A UH Energy-produced white paper, titled “Revitalization of Mature Oil Fields: Opportunities and Challenges of CO2-EOR,” looks at how CO2-EOR could increase U.S. energy supply, reduce carbon emissions and lower the carbon intensity of oil production.

CO2-EOR injects pressurized carbon dioxide into mature oil wells to loosen and push oil trapped underground toward the production wells, allowing operators to extract oil typically left behind. The process permanently stores some CO2 underground, reducing carbon emissions and carbon intensity.

“Injected CO2 works to revitalize mature oil fields by reducing oil viscosity, improving sweep efficiency and restoring reservoir pressure, resulting in incremental oil production beyond primary and secondary recovery,” the report reads. “CO2-EOR also supports permanent carbon storage and by virtue of this will produce uniquely low-carbon intensity oil for global markets.”

Authored by Charles McConnell, executive director of UH's Center for Carbon Management in Energy, and Zhiyuan Li, a UH petroleum engineering doctoral candidate, the paper says that much of the opportunity lies right under the feet of Texas oil companies.

Texas and the Gulf Coast, including its offshore resources, have half of the nation's oil resources considered favorable for the CO2-EOR technology, the report says. According to UH, conventional U.S. oil reservoirs contain 624 billion barrels, with 434 billion barrels still underground, including about 20 billion barrels of proven reserves.

Still, the paper argues that the economics behind CO2-EOR need to be considered. The process’ success depends on a number of factors, including costs of carbon capture, field redevelopment, operations, monitoring, transportation and available tax incentives, according to UH.

Logistically, developing CO2-EOR operations out of older wells and infrastructure presents pros and cons. While using older wells can be more economical, aging infrastructure may require more frequent monitoring, inspection, repair or re-plugging, according to UH.

Ultimately, the report recommends focusing CO2-EOR development on mature oil fields with existing infrastructure, well-understood geology and reliable CO2 supplies. This approach, UH says, could help extend the productive life of existing oil fields while supporting “lower carbon intensity oil for global markets and a significant contribution to energy security.”

Amazon's EV robotaxi service Zook is set to arrive in Houston

EV News

Amazon-owned electric robotaxi ride-hailing service Zoox is zooming into Houston in September.

Initially, self-driving retrofitted SUVs with safety drivers on board will serve downtown Houston, centrally located tourist hotspots, and certain residential neighborhoods. The SUVs will test Houston roads before Zoox rolls out autonomous robotaxis, the company says.

Zoox takes Houston for a test drive

At the outset, Zoox says, a limited number of vehicles will be driven by people to gather data about Houston roads.

“This helps create a detailed picture of each street, from road geometry to traffic lights,” the company says. “Once we have mapped out an area, we will test autonomous driving capabilities. Safety and operational readiness govern the pace of our rollout.”

Zoox says its robotaxi differs from vehicles operated by other ride-hailing services.

The all-electric robotaxi “is purpose-built for autonomous ride-hailing and designed for riders from day one,” the company says. “It has no traditional driving controls and instead has carriage-style seating, sliding glass doors, and features that let the rider personalize their journey.”

To help manage the fleet, Zoox plans to open a depot in Houston for vehicle charging and maintenance, a representative says via email.

Along with Houston, Zoox is launching this month in San Diego. The ride-hailing service already operates in Austin, Dallas, Atlanta, Las Vegas, Los Angeles, Miami, Phoenix, the San Francisco Bay Area, Seattle, and Washington, D.C.

Zoox breaks into “sprawling” Houston market

Zoox describes Houston as its “most sprawling market to date.”

“Driving here means navigating complex service-road networks, unique merging scenarios, and challenging environmental conditions, including severe heat, heavy rain, and urban flooding,” the company says. “It’s a rigorous test of our technology across geography and terrain.”

Zoox will join two other autonomous ride-hailing services in Houston:

  • Waymo began rolling in Houston in February. Alphabet, the parent company of Google, owns Waymo.
  • Electric vehicle manufacturer Tesla began offering robotaxi services earlier this year.

A third Zoox competitor is arriving within the next year. A partnership comprising rideshare provider Uber, EV manufacturer Lucid, and autonomous technology company Nuro plans to launch a robotaxi service in Houston by mid-2027.
