Local energy innovators recognized at annual Houston Innovation Awards

the big winners

This week, the Houston innovation ecosystem celebrated big wins from the year, and members of the energy transition community were recognized alongside other innovators.

The Houston Innovation Awards honored over 40 finalists across categories, naming the 12 winners and honoring the two Trailblazer Legacy Awards at the event. The event, hosted at TMC Helix Park on November 14 named and celebrated the winners, which included four energy transition innovators.

Here's what energy leaders secured wins during the evening.

Corrolytics is a technology startup founded to solve microbiologically influenced corrosion problems for industrial assets. Co-founder and CEO Anwar Sadek says he's collected over $1 million in dilutive and non-dilutive funding from grants and other opportunities thanks to help from mentors. The company won both the Minority-Founded Business category and the People's Choice: Startup of the Year category.

"As a founder, I am always eager to assist and support fellow entrepreneurs, especially those navigating the unique challenges that come with being a BIPOC founder," he says. "With the guidance of mentors, I learned to master the complexities of the application process for grants and other funding opportunities. In turn, I actively share my experiences with other founders, helping them navigate similar paths."

Founded by CEO Cindy Taff, Sage Geosystems is an energy company focused on developing and deploying advanced geothermal technologies to provide reliable power and sustainable energy storage solutions regardless of geography. The company secured the win in the Energy Transition Business category, alongside finalists Amperon, ARIX Technologies, Elementium Materials, InnoVent Renewables, and Tierra Climate.

"Sage Geosystems sets itself apart from competitors with its Geopressured Geothermal Systems, which can be deployed almost anywhere, unlike traditional geothermal technologies that require specific geographic conditions," Taff says. "This flexibility enables Sage to provide a reliable and virtually limitless power supply, making it ideal for energy-intensive applications like data centers."

A finalist in both the Investor of the Year and Ecosystem Builder categories, Juliana Garaizar is the founding partner of Energy Tech Nexus, invests with groups — such as Portfolia, Houston Angel Network, Business Angel Minority Association, and more — locally and beyond.

"I'm a hands on investor," she says. "I offer mentorship and industry and other investor connections. I take advisory roles and board observer seats."

This year, the Houston innovation community suffered the loss of two business leaders who left a significant impact on the ecosystem. Both individuals' careers were recognized with Trailblazer Legacy Awards.

One of the recipients was Scott Gale, executive director of Halliburton Labs, who received the award posthumously. He died on September 24. The award was decided on by the 2024 judges and InnovationMap. Gale was honored alongside Paul Frison, founder of the Houston Technology Center.

“I am immensely proud to honor these two remarkable individuals with the Trailblazer Award this year. It is fitting, as they represent two generations of building Houston’s ecosystem," 2023 Trailblazer Award recipient Brad Burke, managing director of the Rice Alliance and the associate vice president for industry and new ventures within Rice University's Office of Innovation, tells InnovationMap.

"Paul Frison was a pioneering leader who helped establish the Houston Technology Center and fostered the city’s tech ecosystem during the initial technology boom around the year 2000. Scott Gale, through his work at Halliburton Labs over the past five years, has been instrumental in launching Houston’s energy transition ecosystem," he continues. "Both have played pivotal roles in championing technology innovators.”

In honor of his son, Andrew Gale accepted the award with his daughter-in-law, Nicole, during the event.

ExxonMobil to move legal home to Texas, citing business-friendliness

ExxonMobil is poised to move its legal headquarters from New Jersey to Texas in search of a more friendly business environment, the company announced March 10.

The board of directors for the largest U.S.-based oil producing company, which already runs its operations from the Houston suburb of Spring, unanimously recommended to its shareholders that they vote to redomicile the company in Texas.

Shareholders will vote on the change at the company’s annual meeting on May 27. If successful, it will move Exxon’s legal home for the first time since it registered in New Jersey in 1882 as Standard Oil Company — the company later changed its name to Exxon, then merged with Mobil Oil Corp.

“Over the past several years, Texas has made a noticeable effort to embrace the business community,” ExxonMobil Chair and CEO Darren Woods wrote in a statement Tuesday. “In doing so, it has created a policy and regulatory environment that can allow the company to maximize shareholder value. Aligning our legal home with our operating home, in a state that understands our business and has a stake in the company’s success, is important.”

The proposed move will not affect the company’s business operations or employee locations, the company said.

ExxonMobil has been headquartered in Texas since 1989, and about 30% of its employees currently work in the state.

The location of a company’s incorporation dictates the legal, tax and regulatory landscape for the business.

Exxon would join Tesla, Space X and Coinbase as major U.S. companies to redomicile in Texas in recent years as the state moves to become more business friendly.

In 2023, the Legislature passed and Gov. Greg Abbott signed a law that created the Texas Business Court and the 15th Court of Appeals, specialized legal venues designed to handle business and commercial disputes. Those courts began operating in 2024.

Last year, the Legislature also approved a law that made it more difficult to sue board members of companies incorporated in Texas.

“Freed from the stranglehold of over-regulation, Texas is where global brand leaders thrive and jobs for hardworking Texans grow,” Abbott wrote in a Tuesday statement. “I thank ExxonMobil for their decision to redomicile in Texas and for their long-standing partnership with our state. With this decision, Texas will further dominate the corporate landscape and ensure our economic growth reaches new heights.”

Exxon noted the creation of the business courts and other recent legal reforms made by Texas in its statement announcing the decision.

“In making its recommendation, the Board considered Texas’ legal and regulatory environment, including its modernized business statutes and the Texas Business Court, which is designed to resolve complex disputes efficiently,” the statement said.

Texas has benefited from growing frustration among company executives with traditional corporate havens of New Jersey and Delaware. New Jersey sued Exxon in 2022, alleging the company contributed to climate change, which forced the state to pay for cleanup after natural disasters. The lawsuit was dismissed last year.

Delaware remains the nation’s top state for U.S. companies’ legal home.

Coinbase’s CEO wrote last year that the company was reincorporating from Delaware to Texas because the Lone Star State’s legal framework is more predictable and efficient. Tesla reincorporated from Delaware to Texas after a 2024 court ruling ordered CEO Elon Musk to give up a compensation package, finding that the package’s shareholder approval process was “deeply flawed.”
