Houston, often dubbed the “Energy Capital of the World,” is at a pivotal moment in its history. Known for its vast oil and gas reserves, the city is now embracing a new role as a leader in the clean energy transition. This shift is not just about adopting new technologies but also about creatively repurposing existing infrastructure to support sustainable energy solutions.

Houston’s offshore oil wells, many of which are old or abandoned, present a significant opportunity for carbon capture. By repurposing these wells, we can sequester carbon dioxide, reducing greenhouse gas emissions and mitigating climate change. This approach not only utilizes existing infrastructure but also provides a cost-effective solution for carbon management. According to the Greater Houston Partnership, initiatives like these are crucial as Houston aims to lower its climate-changing greenhouse gas emissions. Exxon estimates that just their proposed CCS hub could capture and store 50 million metric tons of CO2 annually by 2030 and 100 million metric tons by 2040.

The proximity of abandoned offshore platforms to the coast makes them ideal candidates for renewable energy substations. These platforms can be transformed into hubs for wind, solar or tidal energy, facilitating the integration of renewable energy into the grid. This repurposing not only maximizes the use of existing structures but also minimizes environmental disruption.

Decommissioned pipelines, which are already in place, offer a ready-made solution for routing renewable energy cables. By using these existing rights of way, Houston can avoid disturbing additional seafloor and reduce the environmental impact of new cable installations. This strategy ensures a smoother transition to renewable energy infrastructure. The U.S. Energy Information Administration notes that Texas, including Houston, leads the nation in wind-generated electricity, highlighting the potential for further renewable energy development.

Onshore oil and gas facilities in Houston also hold potential for clean energy repurposing. Wells that were drilled but never used for oil or gas can be adapted for geological thermal energy storage. This process involves storing excess renewable energy in the form of heat, which can be retrieved when needed, providing a reliable and sustainable energy source. This innovative use of existing wells aligns with Houston’s broader energy transition strategy, which aims to leverage the city’s industrial expertise for a low-carbon future.

Once the land has been remediated, old and abandoned oil fields can be converted into solar farms. This transformation not only provides a new use for previously contaminated land but also contributes to the generation of clean, renewable energy. Solar farms on these sites can help meet Houston’s energy needs while supporting environmental restoration. The Environmental Protection Agency in recent years recognized Houston as the top city in the U.S. for green energy usage, with annual green power usage topping 1 billion kilowatt-hours in 2021.

Houston’s journey towards a clean energy future is a testament to the power of innovation and adaptability. By repurposing existing infrastructure, we can create a sustainable energy landscape that honors the city’s industrial past while paving the way for a greener tomorrow. These strategies highlight the potential for Houston to lead in the clean energy transition, setting an example for cities worldwide.

Houston-born wind energy technology is gearing up for climatetech impact

seeing green

A Houston-based cleantech startup is testing mini wind turbines that it says supply up to 50 percent more power than solar panels — at the same cost.

Aeromine Technologies’ bladeless mini turbines are designed for installation on buildings with large, flat rooftops. These include warehouses, distribution centers, factories, office buildings, apartment buildings, and big-box retail stores. Aeromine says each five-kilowatt unit delivers as much power (5 kilowatts) as 16 rooftop solar panels.

Companies piloting the mini turbines include chemical giant BASF Corp., which is testing the Aeromine system at its manufacturing plant in Wyandotte, Michigan, according to an Aeromine news release.

“Unlike noisy and visually intrusive wind turbines that rely on rotating rotor blades, are prone to maintenance issues, and can harm or kill birds, Aeromine is motionless. The technology leverages aerodynamics similar to airfoils on a race car to capture and amplify each building’s airflow,” the company says.

Requiring 10 percent of the roof space normally needed for solar panels, an Aeromine unit generates around-the-clock energy amid all weather conditions. Each Aeromine system, consisting of 20 to 40 units, can generate up to 100 percent of a building’s onsite energy.

“This is a game-changer, adding new value to the fast-growing rooftop power generation market, helping corporations meet their resilience and sustainability goals with an untapped distributed renewable energy source,” says David Asarnow, co-founder and CEO of Aeromine. “Aeromine’s proprietary technology brings the performance of wind energy to the onsite generation market, mitigating legacy constraints posed by spinning wind turbines and less-efficient solar panels.”

Research conducted with Sandia National Laboratories and Texas Tech University validated Aeromine’s patented technology, the company says.

Carsten Westergaard, founder and chief technology officer at Aeromine, invented the technology. He developed it during his time as a professor of practice at Texas Tech, where he taught graduate students about wind energy technology.

New report finds coal and wind energy usage tied in Texas for the first time

winds of change

In an electrifying sign for the renewables sector of Houston's energy industry, wind for the first time has essentially tied with coal as a power source for Texas homes and businesses.

In 2019, wind (19.97 percent) and coal (20.27 percent) were locked in a statistical dead heat to be the No. 2 energy source for customers of the Electric Reliability Council of Texas, or ERCOT. Natural gas ranked first (40.2 percent). The Austin-based nonprofit manages about 90 percent of the state's electrical grid.

Houston stands to benefit greatly from these winds of change.

Long dominant in the oil and gas industry as the Energy Capital of the World, Houston is adapting to the shifting tide from traditional energy sources to renewable energy sources like wind and solar. Over 30 companies involved in wind energy are based in the Houston area. Major local players in wind energy include BP Wind Energy North America Inc., EDP Renewables North America LLC, and Pattern Energy Group Inc. In addition, many of the state's more than 130 wind-generation projects are operated from Houston.

Bob Harvey, president and CEO of the Greater Houston Partnership, says the region's "unparalleled experience" with massive energy initiatives supplies an edge in the burgeoning renewable energy sector.

"Houston's talent base knows energy, from development to commercial operations, and the region offers a competitive advantage to renewable energy companies looking to develop projects both domestically and around the world," Harvey says. "Houston and Texas are well positioned as leaders who are developing large-scale renewable energy projects in both wind and solar."

Harvey says ERCOT's aggressive pursuit of wind and solar power also bodes well for Houston and the entire state.

"When combined with our natural advantages of great sites for wind and solar, our market structure has made Texas a global leader in the transition to low-carbon power generation," he says. "We expect Houston will continue to play a major role as wind, solar, and other renewable energy sources continue to rise on a global scale."

Susan Sloan, vice president of state affairs at the American Wind Energy Association, notes that Texas leads all states for wind energy, with 25 gigawatts of capacity generated by nearly 14,000 wind turbines. The Lone Star State produces about one-fourth of the country's wind power, and the wind energy industry employs more than 25,000 Texans.

With another 9 gigawatts of capacity coming online, "Texas continues to champion investment in wind energy as the state's electric load continues to increase," says Sloan, who's based in Austin. "Wind is an established and growing part of the Texas energy economy, and will be for years to come."

Texas has made great strides in wind energy in the past decade. In 2010, wind represented only 7.8 percent of ERCOT's power generation and ranked as the grid's No. 4 energy source, while coal stood at 39.5 percent and ranked first.

In September 2019, Norwegian energy research firm Rystad Energy predicted wind will bypass coal as a Texas energy source in 2020. Rystad Energy, which has an office in Houston, expects wind to generate 87 terawatt-hours of electricity in Texas this year compared with 84.4 terawatt-hours from coal. One terawatt-hour equals the output of 1 trillion watts over a one-hour period.

"Texas is just one of many red states that have recently 'gone green' by harnessing their great wind-generation potential," Carlos Torres-Diaz, head of gas market research at Rystad Energy, said in a release. Renewable energy sources like wind "are reaching a level where new installations are not driven solely by policies or subsidies, but by economics," he added.

More power to us

With over 4,600 energy-related businesses employing more than 237,000 people, Houston has earned recognition as the "Energy Capital of the World." But when people think of Houston's energy sector, oil and gas almost automatically come to mind, given that about one-third of the publicly traded oil and gas companies in the U.S. are based in the Houston area.

Yet wind energy is making inroads in Houston. Susan Davenport, senior vice president for economic development at the Greater Houston Partnership, says more than 30 companies in the Houston area operate in the wind energy sector.

"Houston is actively working to grow this sector, so we hope people will seriously think of Houston when they think of renewables in this new era of energy," Davenport says at an April 9 news conference in Houston where the American Wind Energy Association released its 2018 state-of-the-industry report.

That's not to say, though, that Houston is ready to cede its dominance in the oil and gas sector.

"Houston has long held the title of 'Energy Capital of the World,' and we fully intend to maintain that status," Davenport says. "As global energy forecasts continue to show an ever-increasing need for energy, we know oil and gas will be critical for years to come. But at the same time, as that energy mix gets larger, we know an increasing share of energy will come from renewables. And we're already capturing a sizable share [of that market]."

That sizable market share includes venture capital. Of the $5.2 billion in venture capital reeled in by Houston businesses from 2015 to 2017, renewable energy accounted for more than 35 percent, according to the Greater Houston Partnership.

Davenport said Houston is "uniquely suited" to support companies involved in wind energy and other types of renewable energy, thanks to its deep pool of energy-oriented talent.

The American Wind Energy Association's annual report for 2018 shows the wind energy sector employs between 25,000 and 26,000 people in Houston and elsewhere in Texas, up from 24,000 to 25,000 in 2017, with the total investment in Texas wind energy projects sitting at a whopping $46.5 billion. More than one-fifth of wind energy jobs in the U.S. are located in Texas.

In employment, investment, and several other categories, Texas rules as the undisputed leader of the U.S. wind energy industry.

"The success story in Texas continues," says Susan Williams Sloan, the Austin-based vice president of state policy for the American Wind Energy Association.

The report indicates the Lone Star State is home to roughly one-fourth of all U.S. wind power production. If Texas were a country, the wind energy group says, it would rank fifth in the world for wind power capacity, with nearly 25,000 megawatts installed. And with nearly 7,000 megawatts of wind energy projects under construction or development at the end of 2018, Texas is adding more wind energy capacity than what all but two other states actually have installed.

At of the end of 2018, nearly 13,400 wind turbines dotted the state's landscape, mostly in West Texas.

It's not just utilities that are fueling the growth of wind power in Texas. The association calls Texas the "nexus" for non-utility demand for wind power.

Today, 38 non-utility companies have bought or are planning to buy 4,900 megawatts of wind energy in Texas, including Shell Energy, AT&T, Budweiser, ExxonMobil, and Walmart, according to the association.

"Texas continues to lead the nation, with hard work and ingenuity, in harnessing this great American renewable energy resource, literally out of thin air," says Tom Kiernan, CEO of the Washington, D.C.-based American Wind Energy Association. "Texas has a long and storied history of energy production and as [our] report demonstrates, wind is an important part of the state's energy success story. In many ways, the Texas wind story is the story of American wind power."

The association released its 2018 report in advance of WINDPOWER, the wind energy industry's biggest conference, which is set for May 20 to 23 at Houston's George R. Brown Convention Center. More than 8,000 people are expected to attend.

Houston edtech company closes oversubscribed $3M seed round

fresh funding

Houston-based edtech company TrueLeap Inc. closed an oversubscribed seed round last month.

The $3.3 million round was led by Joe Swinbank Family Limited Partnership, a venture capital firm based in Houston. Gamper Ventures, another Houston firm, also participated with additional strategic partners.

TrueLeap reports that the funding will support the large-scale rollout of its "edge AI, integrated learning systems and last-mile broadband across underserved communities."

“The last mile is where most digital transformation efforts break down,” Sandip Bordoloi, CEO and president of TrueLeap, said in a news release. “TrueLeap was built to operate where bandwidth is limited, power is unreliable, and institutions need real systems—not pilots. This round allows us to scale infrastructure that actually works on the ground.”

True Leap works to address the digital divide in education through its AI-powered education, workforce systems and digital services that are designed for underserved and low-connectivity communities.

The company has created infrastructure in Africa, India and rural America. Just this week, it announced an agreement with the City of Kinshasa in the Democratic Republic of Congo to deploy a digital twin platform for its public education system that will allow provincial leaders to manage enrollment, staffing, infrastructure and performance with live data.

“What sets TrueLeap apart is their infrastructure mindset,” Joe Swinbank, General Partner at Joe Swinbank Family Limited Partnership, added in the news release. “They are building the physical and digital rails that allow entire ecosystems to function. The convergence of edge compute, connectivity, and services makes this a compelling global infrastructure opportunity.”

TrueLeap was founded by Bordoloi and Sunny Zhang and developed out of Born Global Ventures, a Houston venture studio focused on advancing immigrant-founded technology. It closed an oversubscribed pre-seed in 2024.

Texas space co. takes giant step toward lunar excavator deployment

Out of this world

Lunar exploration and development are currently hampered by the fact that the moon is largely devoid of necessary infrastructure, like spaceports. Such amenities need to be constructed remotely by autonomous vehicles, and making effective devices that can survive the harsh lunar surface long enough to complete construction projects is daunting.

Enter San Antonio-based Astroport Space Technologies. Founded in San Antonio in 2020, the company has become a major part of building plans beyond Earth, via its prototype excavator, and in early February, it completed an important field test of its new lunar excavator.

The new excavator is designed to function with California-based Astrolab's Flexible Logistics and Exploration (FLEX) rover, a highly modular vehicle that will perform a variety of functions on the surface of the moon.

In a recent demo, the Astroport prototype excavator successfully integrated with FLEX and proceeded to dig in a simulated lunar surface. The excavator collected an average of 207 lbs (94kg) of regolith (lunar surface dust) in just 3.5 minutes. It will need that speed to move the estimated 3,723 tons (3,378 tonnes) of regolith needed for a lunar spaceport.

After the successful test, both Astroport and Astrolab expressed confidence that the excavator was ready for deployment. "Leading with this successful excavator demo proves that our technology is no longer theoretical—it is operational," said Sam Ximenes, CEO of Astroport.

"This is the first of many implements in development that will turn Astrolab's FLEX rover into the 'Swiss Army Knife' of lunar construction. To meet the infrastructure needs of the emerging lunar economy, we must build the 'Port' before the 'Ship' arrives. By leveraging the FLEX platform, we are providing the Space Force, NASA, and commercial partners with a 'Shovel-Ready' construction capability to secure the lunar high ground."

"We are excited to provide the mobility backbone for Astroport's groundbreaking construction technology," said Jaret Matthews, CEO of Astrolab, in a release. "Astrolab is dedicated to establishing a viable lunar ecosystem. By combining our FLEX rover's versatility with Astroport's civil engineering expertise, we are delivering the essential capabilities required for a sustainable lunar economy."

drug money

Houston-based clinical-stage biotechnology company Coya Therapeutics (NASDAQ: COYA) has raised $11.1 million in a private investment round.

India-based pharmaceuticals company Dr. Reddy’s Laboratories Inc. led the round with a $10 million investment, according to a news release. New York-based investment firm Greenlight Capital, Coya’s largest institutional shareholder, contributed $1.1 million.

The funding was raised through a definitive securities purchase agreement for the purchase and sale of more than 2.5 million shares of Coya's common stock in a private placement at $4.40 per share.

Coya reports that it plans to use the proceeds to scale up manufacturing of low-dose interleukin-2 (IL-2), which is a component of its COYA 302 and will support the commercial readiness of the drug. COYA 302 enhances anti-inflammatory T cell function and suppresses harmful immune activity for treatment of Amyotrophic Lateral Sclerosis (ALS), Frontotemporal Dementia (FTD), Parkinson’s disease and Alzheimer’s disease.

The company received FDA acceptance for its investigational new drug application for COYA 302 for treating ALS and FTD this summer. Its ALSTARS Phase 2 clinical trial for ALS treatment launched this fall in the U.S. and Canada and has begun enrolling and dosing patients. Coya CEO Arun Swaminathan said in a letter to investors that the company also plans to advance its clinical programs for the drug for FTD therapy in 2026.

Coya was founded in 2021. The company merged with Nicoya Health Inc. in 2020 and raised $10 million in its series A the same year. It closed its IPO in January 2023 for more than $15 million. Its therapeutics uses innovative work from Houston Methodist's Dr. Stanley H. Appel.
