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.

Google to invest $40 billion in AI data centers in Texas

Google is investing a huge chunk of money in Texas: According to a release, the company will invest $40 billion on cloud and artificial intelligence (AI) infrastructure, with the development of new data centers in Armstrong and Haskell counties.

The company announced its intentions at a meeting on November 14 attended by federal, state, and local leaders including Gov. Greg Abbott who called it "a Texas-sized investment."

Google will open two new data center campuses in Haskell County and a data center campus in Armstrong County.

Additionally, the first building at the company’s Red Oak campus in Ellis County is now operational. Google is continuing to invest in its existing Midlothian campus and Dallas cloud region, which are part of the company’s global network of 42 cloud regions that deliver high-performance, low-latency services that businesses and organizations use to build and scale their own AI-powered solutions.

Energy demands

Google is committed to responsibly growing its infrastructure by bringing new energy resources onto the grid, paying for costs associated with its operations, and supporting community energy efficiency initiatives.

One of the new Haskell data centers will be co-located with — or built directly alongside — a new solar and battery energy storage plant, creating the first industrial park to be developed through Google’s partnership with Intersect and TPG Rise Climate announced last year.

Google has contracted to add more than 6,200 megawatts (MW) of net new energy generation and capacity to the Texas electricity grid through power purchase agreements (PPAs) with energy developers such as AES Corporation, Enel North America, Intersect, Clearway, ENGIE, SB Energy, Ørsted, and X-Elio.

Water demands

Google’s three new facilities in Armstrong and Haskell counties will use air-cooling technology, limiting water use to site operations like kitchens. The company is also contributing $2.6 million to help Texas Water Trade create and enhance up to 1,000 acres of wetlands along the Trinity-San Jacinto Estuary. Google is also sponsoring a regenerative agriculture program with Indigo Ag in the Dallas-Fort Worth area and an irrigation efficiency project with N-Drip in the Texas High Plains.

In addition to the data centers, Google is committing $7 million in grants to support AI-related initiatives in healthcare, energy, and education across the state. This includes helping CareMessage enhance rural healthcare access; enabling the University of Texas at Austin and Texas Tech University to address energy challenges that will arise with AI, and expanding AI training for Texas educators and students through support to Houston City College.
