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.

Google to invest $1B in data center tech, clean energy in Texas

coming in hot

Google is making a big investment in Texas to the tune of $1 billion.

According to a news release from the company, the tech giant will spend more than $1 billion to support its cloud and data center infrastructure and expand its commitment to clean energy.

The $1 billion will be spent on data center campuses in Midlothian and Red Oak to help meet growing demand for Google Cloud, AI innovations, and other digital products and services such as Search, Maps, and Workspace.

In addition to its data center investment, Google has also forged long-term power purchase agreements with Houston-based Engie, as well as Madrid-based entities Elawan, Grupo Cobra, and X-ELIO for solar energy based in Texas. Together, these new agreements are expected to provide 375 MW of carbon-free energy capacity, which will help support Google’s operations in Texas.

These agreements were facilitated through LEAP (LevelTen Energy’s Accelerated Process), which was co-developed by Google and LevelTen Energy to make sourcing and executing clean energy PPAs more efficient, and contributes to the company’s ambitious 2030 goal to run on 24/7 carbon-free energy on every grid where it operates.

The company has contracted with energy partners to bring more than 2,800 megawatts (MW) of new wind and solar projects to the state. Google’s CFE percentage in the ERCOT grid region, which powers its Texas data centers, nearly doubled from 41 percent in 2022 to 79 percent in 2023.

The initiatives were announced at a conference in Midlothian on August 15, attended by business leaders and politicians including U.S. Congressman Jake Ellzey, c, Ted Cruz, and Citi CIO Shadman Zafar.

The Dallas cloud region is part of Google Cloud's global network of 40 regions that delivers services to large enterprises, startups, and public sector organizations.

In a statement, Piazza said that "expanding our cloud and data center infrastructure in Midlothian and Red Oak reflects our confidence in the state's ability to lead in the digital economy."

Data centers are the engines behind the growing digital economy. Google has helped train more than 1 million residents in digital skills through partnerships with 590 local organizations, including public libraries, chambers of commerce, and community colleges.

In addition to its cloud region and Midlothian data center, Google has offices in Austin, Dallas, and Houston. The new Google’s total investment in Texas to more than $2.7 billion.

Nuclear engineer and entrepreneur Nathan Childress wants consumers to capture their own ray of sunlight to brighten the prospect of making clean energy a bigger part of the power grid. That's why he founded Solar Slice. The new venture offers a fulfilling way to encourage and promote solar energy and a greener planet.

Although trained in nuclear power plant design, solar power drew his interest as a cheaper and more accessible alternative, and Childress tells InnovationMap that he thinks that the transition to cleaner energy, in Texas especially, needs to step up.

Recent studies show that 80 to 90 percent of the money invested into fighting climate change “aren’t going to things that people actually consider helpful,” Childress says, adding that “they’re more just projects that sound good, that are not actually taking any action." Read more.

Houston entrepreneur launches new venture to shine light on sustainability

energy transition

A Houston nuclear engineer and entrepreneur wants consumers to capture their own ray of sunlight to brighten the prospect of making clean energy a bigger part of the power grid.

Solar Slice Founder Nathan Childress says his new venture offers a fulfilling way to encourage and promote solar energy and a greener planet. An experienced entrepreneur, Childress also serves as founder and CEO of technology software company Macorva.

Although trained in nuclear power plant design, solar power drew his interest as a cheaper and more accessible alternative, and Childress tells InnovationMap that he thinks that the transition to cleaner energy, in Texas especially, needs to step up.

With energy demand skyrocketing, and the push toward renewable solutions, solar seems like a safe bet for Childress, a former competitive high-stakes poker player. Childress cites a recent Yale University study that says 63 percent of Americans “feel a personal responsibility to help reduce global warming.”

But some studies show that 80 to 90 percent of the money invested into fighting climate change “aren’t going to things that people actually consider helpful,” he says.

“They’re more just projects that sound good, that are not actually taking any action,” says Childress, who has called Houston home for 25 years. He received his doctorate in medical physics at M.D. Anderson Cancer Center, where he worked on software that provided radiation therapy for patients.

The initial Kickstarter fundraising round, which will be launched soon, will finance the construction of one utility-scale solar farm, on about five to 10 acres, which would produce about 1 megawatt, or 1,000 kilowatts, of clean energy. The plant would make enough energy to power about 200 average homes.

Childress says interest has been strong, with several thousand signed up on the Kickstarter launch list. Some who are signed up expressed interest in a subscription, he said, and that may be offered later. Initially, though, for a one-time purchase of $95, a Solar Slice client can purchase one virtual 50W slice of solar power, produced by the farm. Over its lifetime, Childress says, that one purchase can offset three tons of carbon dioxide.

The app tracks carbon offsetting, and energy production for the slice, showing a client “exactly how much I have helped the climate, here’s exactly how (many) emissions I have prevented from putting in the atmosphere,” he says.

The energy produced by five slices can offset the average American’s carbon footprint for a year, and the power generated by the solar farm will be sold to the electric grid. As clients purchase more slices, they can earn eco-credits to donate to other climate-friendly partners, to plant trees or create pollinator habitats.

While Solar Slice is a for-profit venture, contributors won’t get rich or even make money from their purchase. Rather, it provides validation.

“Our focus is maximizing the real world impact, not for financial gain. This is not something people sign up (for) to make money. We’re really clear about that,” Childress says. “I want to show that it’s possible to have a for-profit company that is sustainable, that does good work.

“And hopefully, we can be part of the spirit…for a bigger movement, and for consumers and business, especially, to do things that matter.”

The largest U.S. solar plants are in Nevada and California, and those states are sites under consideration, but Childress says Texas is the most likely home for the initial project. The ten largest utility-scale solar plants in Texas by capacity are all in far west or central parts of the state, according to the state comptroller’s office.

Childress has a team of four, who are handling the marketing, plant design and site scouting, and hopes to hire five to 10 more, depending on response and growth. He says the Solar Slice consumer can directly connect in real time to the contribution that their purchase will make toward a green energy future.

“That was our inspiration..let’s start something that is really making a difference..and making really clear to the individuals what’s being done,” he says.

Solar energy has become a growing source of power for Texas, comprising about 6 percent of the state’s energy generation, as of 2022, the comptroller’s office says.

The state ranks first in projected growth of solar energy over the next five years, with more than 9,500 operating solar plants, and many thousands more announced, according to the state Public Utility Commission.

“We would absolutely love to make this into something where we are building plants around the nation, around the world,” Childress he says.

However, resistance to alternative energy projects like solar and wind, especially on a large scale, remains in some quarters.

Obtaining site permits for swaths of land can be also a challenge. For example, a recent survey by Berkeley Lab of 123 professionals from 62 unique, large-scale wind and solar energy facilities showed that about one-third of wind and solar siting applications in the past five years were canceled.

Half of the projects experienced delays of six months or longer. And according to the survey, developers expect the trend to continue, and become more expensive to address.

However, another Berkeley Lab survey of residents who live within three miles of a solar power plant showed that most view the plant positively. The larger the plant, the more negative the response in the survey. The smaller the farm, the more positive the reactions.

Childress says many of the common objections to utility-scale solar farms are misguided, and incorrect. For example, the concern that they would take over available farmland or take up too much space.

He says that even if the entire U.S. power grid relied solely on solar power, the plants would occupy not even a half percent of available land, which is about one percent farmland.

Sunny Houston fails to place on Thumbtack's new list. Photo by Adrian N on Unsplash

New report throws shade on Houston's renewable energy use in 'solar cities' ranking

(Not so) sunny news

As the cost of solar panel installation becomes more attainable to homeowners, more Americans are willing to reduce their carbon emissions and their electricity bills in the process.

So just where does Houston rank in new tech like solar panel installation? According to a new report from home service management platform Thumbtack, it doesn't.

Houston, which has no shortage of sun — as residents are well aware — fails to place in Thumbtack's new list of the top 15 most "solar" cities in the United States.

Austin leads the way for Texas, ranking the No. 3 most “solar” city in the U.S., per Thumbtack. Austin, with the highest net-new solar panel installations within the past year in Texas, splits up four Californian cities in the top five. Only San Diego (No. 1) and Los Angeles (No. 2) outranked Austin.

San Antonio follows not behind atNo. 9 and just outside the top 10 is Dallas-Fort Worth at No. 11.

For the curious, Texas Property Code 202.010 forbids homeowner associations from restricting the installation of solar panels, so any Texas homeowner can do it as long as they follow the standard procedure for “improving” their home to comply with a separate state law.

Thumbtack home expert David Steckel said in a press release that they chose to focus the report on cities with the most new solar installations because they wanted to “celebrate those [cities] making the biggest change.”

“When we looked at all solar projects – from installations to modifications, repairs, consultations and more – we found that unsurprisingly, California dominated the list with 9 out of the top 10 spots – given their long-term commitment to and adoption of solar energy," he said. "We really wanted to celebrate cities that are seeing a shift in behavior.”

The top 10 most “solar” cities in the U.S. are:

  • No. 1 – San Diego
  • No. 2 – Los Angeles
  • No. 3 – Austin
  • No. 4 – Palm Springs, California
  • No. 5 – San Francisco
  • No. 6 – Las Vegas
  • No. 7 – Phoenix
  • No. 8 – Orlando
  • No. 9 – San Antonio
  • No. 10 – Tampa, Florida

Steckel said the company has seen a year-over-year increase of up to 96 percent in solar energy projects among consumers for March 2023.

“We recently found that 71 percent of Americans are prioritizing sustainable, energy-efficient home improvement projects this year – with more than one-third of Americans planning to install solar panels in 2023 – showing an accelerating change in consumer behavior,” he said.

Houston charges up new program to help locals buy and install affordable solar panels

sunny days

Alternative-energy-seeking locals now have a sunny way to buy into a solar. The City of Houston has launched Texas Solar SwitchHouston, a new program aimed at helping Houstonians purchase and install rooftop solar panels and battery storage.

In partnership with Solar United Neighbors, the Solar Switch program offers hassle-free way to purchase solar panels by creating a massive, group discount for residents, be it home or small business needs.

This comes with the new Inflation Reduction Act’s clean energy incentives and is part of the City of Houston's Climate Action Plan goal to generate 5 million MWh per year of local solar, per a press release. Customers who install solar also receive a 30-percent tax credit, thanks to the The Inflation Reduction Act.

Registration for the program is free and available online. The City of Houston assures that there is "no obligation for homeowners to purchase solar panels." Discounts and installers are determined through a competitive auction process, per the City.

"With energy prices increasing, homeowners and small businesses are looking for opportunities to save on their energy bills and increase their resilience to climate-related events," said Mayor Sylvester Turner. "Texas Solar Switch Houston provides our community with a simple and straightforward way to become better informed about solar energy and access a competitive offer from a vetted, experienced solar installation company."

Signed and passed into law by the Biden Administration in August, the Inflation Reduction Act will invest some $369 billion in domestic energy production and manufacturing with a goal of reducing carbon emissions by 40 percent by 2030. That federal mandate means locals can now take steps towards power backup, while potentially easing up on the beleaguered Texas grid.

“More and more Houstonians are looking to solar and battery storage for self-sufficiency, which has the added benefit of making our grid more resilient,” said Hanna Mitchell, Texas program director for Solar United Neighbors, in a statement. “With the recent passage of the IRA, now is a particularly good time to go solar.”

The MHCole Pipeline aims to find cancer-specific targets and develop personalized vaccines. Woody is also a junior research associate at the UH Sequencing Core and works in Dr. Steven Hsesheng Lin’s lab at MD Anderson Cancer Center.

“Cole’s work ethic and dedication are unmatched,” Preethi Gunaratne, director of the UH Sequencing Core and professor of Biology & Biochemistry at NSM, said in a news release. “He consistently worked 60 to 70 hours a week, committing himself to learning new techniques and coding the MHCole pipeline.”

Woody plans to earn his MD-PhD and has been accepted into the Harvard/MIT MD-PhD Early Access to Research Training (HEART) program. According to UH, recipients of the Goldwater Scholarship often go on to win various nationally prestigious awards.

"Cole’s ability to independently design and implement such a transformative tool at such an early stage in his career demonstrates his exceptional technical acumen and creative problem-solving skills, which should go a long way towards a promising career in immuno-oncology,” Gunaratne added in the release.

Houston founder on shaping the future of medicine through biotechnology and resilience

Guest Column

Living with chronic disease has shaped my life in profound ways. My journey began in 5th grade when I was diagnosed with Scheuermann’s disease, a degenerative disc condition that kept me sidelined for an entire year. Later, I was diagnosed with hereditary neuropathy with liability to pressure palsies (HNPP), a condition that significantly impacts nerve recovery. These experiences didn’t just challenge me physically, they reshaped my perspective on healthcare — and ultimately set me on my path to entrepreneurship. What started as personal health struggles evolved into a mission to transform patient care through innovative biotechnology.

A defining part of living with these conditions was the diagnostic process. I underwent nerve tests that involved electrical shocks to my hands and arms — without anesthesia — to measure nerve activity. The pain was intense, and each test left me thinking: There has to be a better way. Even in those difficult moments, I found myself thinking about how to improve the tools and processes used in healthcare.

HNPP, in particular, has been a frustrating condition. For most people, sleeping on an arm might cause temporary numbness that disappears in an hour. For me, that same numbness can last six months. Even more debilitating is the loss of strength and fine motor skills. Living with this reality forced me to take an active role in understanding my health and seeking solutions, a mindset that would later shape my approach to leadership.

Growing up in Houston, I was surrounded by innovation. My grandfather, a pioneering urologist, was among the first to introduce kidney dialysis in the city in the 1950s. His dedication to advancing patient care initially inspired me to pursue medicine. Though my path eventually led me to healthcare administration and eventually biotech, his influence instilled in me a lifelong commitment to medicine and making a difference.

Houston’s thriving medical and entrepreneurial ecosystems played a critical role in my journey. The city’s culture of innovation and collaboration provided opportunities to explore solutions to unmet medical needs. When I transitioned from healthcare administration to founding biotech companies, I drew on the same resilience I had developed while managing my own health challenges.

My experience with chronic disease also shaped my leadership philosophy. Rather than accepting diagnoses passively, I took a proactive approach questioning assumptions, collaborating with experts, and seeking new solutions. These same principles now guide decision-making at FibroBiologics, where we are committed to developing groundbreaking therapies that go beyond symptom management to address the root causes of disease.

The resilience I built through my health struggles has been invaluable in navigating business challenges. While my early career in healthcare administration provided industry insights, launching and leading companies required the same determination I had relied on in my personal health journey.

I believe the future of healthcare lies in curative treatments, not just symptom management. Fibroblast cells hold the promise of engaging the body’s own healing processes — the most powerful cure for chronic diseases. Cell therapy represents both a scientific breakthrough and a significant business opportunity, one that has the potential to improve patient outcomes while reducing long-term healthcare costs.

Innovation in medicine isn’t just about technology; it’s about reimagining what’s possible. The future of healthcare is being written today. At FibroBiologics, our mission is driven by more than just financial success. We are focused on making a meaningful impact on patients’ lives, and this purpose-driven approach helps attract talent, engage stakeholders, and differentiate in the marketplace. Aligning business goals with patient needs isn’t just the right thing to do, it’s a powerful model for sustainable growth and lasting innovation in biotech.

Houston researchers make headway on affordable, sustainable sodium-ion battery

Energy Solutions

A new study by researchers from Rice University’s Department of Materials Science and NanoEngineering, Baylor University and the Indian Institute of Science Education and Research Thiruvananthapuram has introduced a solution that could help develop more affordable and sustainable sodium-ion batteries.

The findings were recently published in the journal Advanced Functional Materials.

The team worked with tiny cone- and disc-shaped carbon materials from oil and gas industry byproducts with a pure graphitic structure. The forms allow for more efficient energy storage with larger sodium and potassium ions, which is a challenge for anodes in battery research. Sodium and potassium are more widely available and cheaper than lithium.

“For years, we’ve known that sodium and potassium are attractive alternatives to lithium,” Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering at Rice, said in a news release. “But the challenge has always been finding carbon-based anode materials that can store these larger ions efficiently.”

Lithium-ion batteries traditionally rely on graphite as an anode material. However, traditional graphite structures cannot efficiently store sodium or potassium energy, since the atoms are too big and interactions become too complex to slide in and out of graphite’s layers. The cone and disc structures “offer curvature and spacing that welcome sodium and potassium ions without the need for chemical doping (the process of intentionally adding small amounts of specific atoms or molecules to change its properties) or other artificial modifications,” according to the study.

“This is one of the first clear demonstrations of sodium-ion intercalation in pure graphitic materials with such stability,” Atin Pramanik, first author of the study and a postdoctoral associate in Ajayan’s lab, said in the release. “It challenges the belief that pure graphite can’t work with sodium.”

In lab tests, the carbon cones and discs stored about 230 milliamp-hours of charge per gram (mAh/g) by using sodium ions. They still held 151 mAh/g even after 2,000 fast charging cycles. They also worked with potassium-ion batteries.

“We believe this discovery opens up a new design space for battery anodes,” Ajayan added in the release. “Instead of changing the chemistry, we’re changing the shape, and that’s proving to be just as interesting.”
