The global energy sector is on an exhilarating trajectory, teeming with promising technologies and unprecedented opportunities for a sustainable future. Yet, we find ourselves grappling with the challenges of reliability and affordability. As both a researcher in the field of power electronics and a consumer with bills to pay, I find myself experiencing mixed feelings.

As a researcher, I am thrilled by the progress we have achieved, particularly in energy conversion. The exponential growth of renewable energy technologies in Texas and beyond, including wind turbines and solar PV systems, is cause for celebration. These innovations, coupled with supportive policies, have facilitated widespread deployment and the potential to significantly reduce greenhouse gas emissions, combat climate change, and create a brighter future for our children.

While renewable energy resources can play a crucial role in maintaining the supply-demand balance of the grid, as they did by performing very well during the recent 2023 Texas heat wave, their intermittent and unpredictable nature can also pose a significant challenge to the power system. Unlike traditional power plants that operate continuously, wind turbines and solar PV systems rely on weather conditions for optimal performance. Fluctuations in wind speed, cloud cover, and sunlight intensity can lead to imbalances between energy supply and demand. This imbalance will worsen as the anticipated influx of electric vehicles and their charging needs come into play.

The volatility of renewables contributes to price fluctuations in the electricity market, which not only affects consumers but also raises concerns about grid resilience during extreme weather events. My electricity bill increased by over 20 percent compared to last year, partly caused by inflation, but mainly due to higher operational costs in the Texas electricity market.

Texas witnessed firsthand the consequences of a not-so-resilient grid through the severe power outages experienced during the "Polar Vortex" in February 2021. These outages not only disrupted lives but also disproportionately impacted vulnerable populations. During that time, my wife was expecting our second child. Enduring two nights in our frigid home without electricity or a fireplace was an ordeal that we navigated relatively unscathed. But it made me think of those less fortunate. These circumstances underscore the importance of establishing a robust, dependable and affordable electrical power system.

Balancing renewable energy growth and grid resilience requires a multifaceted approach:

  1. Investment in Infrastructure and Storage: It is crucial to strengthen the grid and ensure a reliable power supply. Upgrading transmission and distribution systems, integrating advanced monitoring and control technologies, and enhancing grid interconnections are essential. The Texas Legislature established the Powering Texas Forward Act, also known as Senate Bill 2627, a taxpayer-funded loan program, to encourage investment. While excluding certain renewable energy facilities and electric energy storage, it recognizes the need for a reliable grid. Hydrogen fuel cell generation facilities could be a potential solution, providing clean and stable energy while remaining eligible for the loan program. Additionally, implementing large-scale energy storage systems utilizing batteries and hydrogen storage technologies can mitigate renewable energy volatility by storing excess energy until needed. The Texas energy industry's push for these advances is a significant step in the right direction.
  2. Diversification of Energy Sources: While renewables play a crucial role in decarbonization, a mix of renewable sources, natural gas, and other low-carbon resources is necessary for the foreseeable future. Implementing carbon capture, utilization, and storage (CCUS) technologies across industries can mitigate associated climate impacts. The failure of Senate Bill 624, which would have had significant repercussions for wind and solar facilities, indicates that Texas legislators are genuinely concerned about clean, alternative sources of energy. However, a lot more needs to be done, including coordinated actions between federal, state, and international governments, to address the urgent issue of climate change. Texas can leverage its hydrocarbon/energy expertise to produce economical green and blue hydrogen, advanced fuel cells and hydrogen-based internal combustion engine technologies, enabling a smoother energy transition in terms of usage and jobs.
  3. Educating the General Public: It is critical to help people understand the necessity of modernizing our energy infrastructure; the benefits and opportunities it brings and the transformations we can expect. Institutions like the University of Houston play a crucial role in advancing clean energy technologies and educating the future energy workforce. The establishment of the Texas University Fund (TUF), with a budget of over $3 billion, through a constitutional amendment in November 2023, will be a pivotal step toward this goal.

When addressing the energy transformation and grid resilience dilemma, the real-life impact on human beings must be of prime importance. Our leaders should focus on a balanced approach considering grid infrastructure investment, diversification of energy sources, energy storage solutions, and public education. By adopting this multifaceted strategy, we can ensure a reliable, resilient, and affordable energy future.

big win

A University of Houston professor has been selected by a national organization to “contribute to the understanding, management and reduction of systemic risk in offshore energy activities.”

The Gulf Research Program of the National Academies of Sciences, Engineering, and Medicine announced that Harish Krishnamoorthy, assistant professor of electrical and computer engineering at the University of Houston, is one of four selected early-career research fellows in the Offshore Energy Safety track. Krishnamoorthy is the first researcher from UH selected for the recognition.

“I am happy and honored to be the first one, but hopefully there will be a lot more in the coming years,” Krishnamoorthy says in a UH news release.

The award, which isn't granted based on a specific project, includes a $76,000 grant, mentor support, and access to a network of current and past cohorts.

Created in 2013, the program is an independent, science-based program founded as part of legal settlements with the companies involved in the 2010 Deepwater Horizon disaster. Its goal is "to enhance offshore energy system safety and protect human health and the environment by catalyzing advances in science, practice and capacity, generating long-term benefits for the Gulf of Mexico region and the nation," the release reads.

“These exceptional individuals are working hard to pursue new research, technical capabilities, and approaches that address some of the greatest challenges facing the Gulf and Alaska regions today,” says Karena Mary Mothershed, senior program manager for the Gulf Research Program’s Board on Gulf Education and Engagement. “We are incredibly excited to announce these new Early-Career Research Fellows, and to continue supporting them as they make lasting impacts.”

Krishnamoorthy, who also serves as associate director of the Power Electronics, Microgrids and Subsea Electric Systems Center at UH, has expertise is in power electronics, power converters, and offshore technologies. His research interests include high-density power conversion for grid interface of energy systems, machine learning-based methods for improvement in quality and reliability of power electronics, advanced electronics and control for mission-critical applications.

According to Krishnamoorthy, there are around 1,500 offshore rigs — with a large amount located North Sea and the Gulf of Mexico. There's a need to improve existing systems, according to Krishnamoorthy, and this process of evolving the grid comes with safety risks and challenges.

“When there are so many electronics involved, safety and reliability are going to be very critical,” Krishnamoorthy says in he release. “I have been looking at safety aspects a lot in my research as well as how to connect subsea oil and gas systems with offshore renewable systems.”

In 2022, Krishnamoorthy was recognized as an OTC Emerging Leader at the Offshore Technology Conference for his contributions to offshore safety and workforce development in offshore, as well as reducing the carbon emissions.

Rice launches 'brain economy' initiative at World Economic Forum

brain health

Rice University has launched an initiative that will position “brain capital” as a key asset in the 21st century.

Rice rolled out the Global Brain Economy Initiative on Jan. 21 at the World Economic Forum in Davos, Switzerland.

“This initiative positions brain capital, or brain health and brain skills, at the forefront of global economic development, particularly in the age of artificial intelligence,” the university said in a news release.

The Rice-based initiative, whose partners are the University of Texas Medical Branch in Galveston and the Davos Alzheimer’s Collaborative, aligns with a recent World Economic Forum and McKinsey Health Institute report titled “The Human Advantage: Stronger Brains in the Age of AI,” co-authored by Rice researcher Harris Eyre. Eyre is leading the initiative.

“With an aging population and the rapid transformation of work and society driven by AI, the urgency has never been greater to focus on brain health and build adaptable human skills—both to support people and communities and to ensure long-term economic stability,” says Amy Dittmar, a Rice provost and executive vice president for academic affairs.

This initiative works closely with the recently launched Rice Brain Institute.

In its first year, the initiative will establish a global brain research agenda, piloting brain economy strategies in certain regions, and introducing a framework to guide financial backers and leaders. It will also advocate for public policies tied to the brain economy.

The report from the McKinsey Health Institute and World Economic Forum estimates that advancements in brain health could generate $6.2 trillion in economic gains by 2050.

“Stronger brains build stronger societies,” Eyre says. “When we invest in brain health and brain skills, we contribute to long-term growth, resilience, and shared prosperity.”

Rice Alliance and the Ion leader Brad Burke to retire this summer

lasting legacy

Brad Burke—a Rice University associate vice president who leads the Ion District’s Rice Alliance for Technology and Entrepreneurship and is a prominent figure in Houston’s startup community—is retiring this summer after a 25-year career at the university.

Burke will remain at the Rice Alliance as an adviser until his retirement on June 30.

“Brad’s impact on Rice extends far beyond any single program or initiative. He grew the Rice Alliance from a promising campus initiative into one of the most respected university-based entrepreneurship platforms,” Rice President Reginald DesRoches said in a news release.

During Burke’s tenure, the Rice Business School went from unranked in entrepreneurship to The Princeton Review’s No. 1 graduate entrepreneurship program for the past seven years and a top 20 entrepreneurship program in U.S. News & World Report’s rankings for the past 14 years.

“Brad didn’t just build programs — he built an ecosystem, a culture, and a reputation for Rice that now resonates around the world,” said Peter Rodriguez, dean of the business school. “Through his vision and steady leadership, Rice became a place where founders are taken seriously, ideas are rigorously supported, and entrepreneurship is embedded in the fabric of the university.”

One of Burke’s notable achievements at Rice is the creation of the Rice Business Plan Competition. During his tenure, the competition has grown from nine student teams competing for $10,000 into the world’s largest intercollegiate competition for student-led startups. Today, the annual competition welcomes 42 student-led startups that vie for more than $1 million in prizes.

Away from Rice, Burke has played a key role in cultivating entrepreneurship in the energy sector: He helped establish the Energy Tech Venture Forum along with Houston Energy and Climate Startup Week.

Furthermore, Burke co-founded the Texas University Network for Innovation and Entrepreneurship in 2008 to bolster the entrepreneurship programs at every university in Texas. In 2016, the Rice Alliance assumed leadership of the Global Consortium of Entrepreneurship Centers.

In 2023, Burke received the Trailblazer Award at the 2023 Houston Innovation Awards and was recognized by the Deshpande Foundation for his contributions to innovation and entrepreneurship in higher education.

“Working with an amazing team to build the entrepreneurial ecosystem at Rice, in Houston, and beyond has been the privilege of my career,” Burke said in the release. “It has been extremely gratifying to hear entrepreneurs say our efforts changed their lives, while bringing new innovations to market. The organization is well-positioned to help drive exponential growth across startups, investors, and the entrepreneurial ecosystem.”

Starting April 15, John “JR” Reale Jr. will serve as interim associate vice president at Rice and executive director of the Rice Alliance. He is managing director of the alliance. Reale is co-founder of the Station Houston startup hub and a startup investor. He was also recently named director for startups and investor engagement at the Ion.

“The Rice Alliance has always been about helping founders gain advantages to realize their visions,” Reale said. “Under Brad’s leadership, the Rice Alliance has become a globally recognized platform that is grounded in trust and drives transformational founder outcomes. My commitment is to honor what Brad has built and led while continuing to serve our team and community, deepen relationships and deliver impact.”

Burke joined the Houston Innovators Podcast back in 2022. Listen to the full interview here.

Houston team uses CPRIT funding to develop nanodrug for cancer immunotherapy

cancer research

With a relative five-year survival rate of 50 percent, pancreatic cancer is a diagnosis nobody wants. At 60 percent, the prognosis for lung cancer isn’t much rosier. That’s because both cancers contain regulatory B cells (Bregs), which block the body’s natural immunity, making it harder to fight the enemies within.

Newly popular immunotherapies in a category known as STING agonists may stimulate natural cancer defenses. However, they can also increase Bregs while simultaneously causing significant side effects. But Wei Gao, assistant professor of pharmacology at the University of Houston College of Pharmacy, may have a solution to that conundrum.

Gao and her team have developed Nano-273, a dual-function drug, packaged in an albumin-based particle, that boosts the immune system to help it better fight pancreatic and lung cancers. Gao’s lab recently received a $900,000 grant from the Cancer Prevention and Research Institute of Texas (CPRIT) to aid in fueling her research into the nanodrug.

“Nano-273 both activates STING and blocks PI3Kγ—a pathway that drives Breg expansion, while albumin nanoparticles help deliver the drug directly to immune cells, reducing unwanted side effects,” Gao said in a press release. “This approach reduces harmful Bregs while boosting immune cells that attack cancer, leading to stronger and more targeted anti-tumor responses.”

In studies using models of both pancreatic and lung cancers, Nano-273 has shown great promise with low toxicity. Its best results thus far have involved using the drug in combination with immunotherapy or chemotherapy.

With the CPRIT funds, Gao and her team will be able to charge closer to clinical use with a series of important steps. Those include continuing to test Nano-273 alongside other drugs, including immune checkpoint inhibitors. Safety studies will follow, but with future patients in mind, Gao will also work toward improving her drug’s production, making sure that it’s safe and high-quality every time, so that it is eventually ready for trials.

Gao added: “If successful, this project could lead to a new type of immunotherapy that offers lasting tumor control and improved survival for patients with pancreatic and lung cancers, two diseases that urgently need better treatments."
