Harish Krishnamoorthy, assistant professor of electrical and computer engineering at the University of Houston, has been selected by the Gulf Research Program of the National Academies of Sciences, Engineering, and Medicine as an early-career research fellow in the Offshore Energy Safety track. He and four other fellows will “contribute to the understanding, management, and reduction of systemic risk in offshore energy activities.”
He is the first UH professor to win this GRP early-career research fellowship. “I am happy and honored to be the first one, but hopefully there will be a lot more in the coming years,” Krishnamoorthy said.
With expertise in power electronics, power converters, and offshore technologies, Krishnamoorthy was recognized as an “OTC Emerging Leader” at the 2022 Offshore Technology Conference for “contributions to promoting workforce development in offshore with a strong focus on enhancing the safety and reliability of the electrical power systems and equipment, as well as reducing the carbon emissions.”
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.
Krishnamoorthy, who is also associate director of the Power Electronics, Microgrids, and Subsea Electric Systems Center at UH, said the Gulf of Mexico offers various challenges and opportunities.
He estimates there are about 1,500 oil and gas rigs located offshore across the globe, with the largest share in the North Sea and the Gulf of Mexico. The current electric distribution system of oil and gas platforms is characterized as a weak electric grid in need of much improvement.
In addition, even though there are no large-scale offshore wind farms currently installed in the Gulf of Mexico, the recent initiatives by the federal government have raised interest in the idea. Several oil and gas companies, such as Shell, Chevron, and Exxon, see this as an opportunity to cut their carbon emissions and are actively looking to contribute to the integration of offshore wind energy systems with subsea energy production activities. Moreover, the potential development of hydrogen as an “energy carrier” of the future has added a new dimension to offshore energy production and transportation activities.
All of these future possibilities come with increased safety challenges. “When there are so many electronics involved, safety and reliability are going to be very critical,” Krishnamoorthy said. “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.”
He recalled the Deepwater Horizon disaster in 2010. “If the equipment were functioning properly, probably 11 people wouldn’t have lost their lives,” he said. “I am working on power converters and circuit breakers as well as intelligent monitoring and control systems that will help improve safety and reliability in the field.”
The early-career award is not attached to a specific project, which allows fellows to take on bold research they might not otherwise be able to pursue. Each of them will receive a $76,000 award, mentoring support, and a built-in network of current and past cohorts. Krishnamoorthy said he is looking forward to using the funds to further his research work; work with mentor Ramanan Krishnamoorti, professor of petroleum engineering and vice president of energy and innovation at UH; and connect with a community of like-minded fellows.
“The opportunity to collaborate, learn and grow this award offers are truly exciting,” Krishnamoorthy said.
