A team of researchers in Houston are developing the next generation of miniaturized pulsed power systems — a technology that was key to the creation of x-ray machines, then MRI machines, and more.

University of Houston researchers led by Harish Krishnamoorthy, Cullen College assistant professor of electrical and computer engineering, are working to develop the next generation of miniaturized pulsed power systems. X-rays, MRIs, and similar technology are deeply intertwined with the nuclear age and the mid-20th century. Additionally, pulsed power systems have been used to create other military weapons, such as radar systems and rail guns.

The research is was published in IEEE Transactions on Industrial Electronics. In the paper, the researchers propose creating a mini-pulsed power system that can shrink the system’s energy storage components, such as capacitors, and deliver an immediate surge of power, a recent UH news release summarizes. According to the paper, energy storage can be reduced to less than one-tenth the size of what conventional pulsed power systems use.

“We’re essentially creating a small high-density energy storage machine that will help with reducing the space these machines use, which will save hundreds of thousands of dollars in material costs and improve their reliability,” Krishnamoorthy says.

Recently, the U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) awarded the research team a $1 million grant to build their gallium nitride (GaN)-based miniaturized pulsed power system. The team will be conducting the project alongside scientists from Harvard University and Schlumberger, who are sub-recipients of the grant.

“Initially we’ll make a compact pulsed power supply for extreme environment fluid characterization that can disruptively reduce the cost of downhole well logging tools used in fossil and geothermal energy production. This will be followed by a miniaturized converter suitable for mobile hand-held MRI machines. However, we think that we can extend our technology to make small water-purification systems, pulsed laser systems and pulsed electro-magnetic radiation sources,” says Krishnamoorthy.

A new pavilion being introduced at this year’s Offshore Technology Conference (OTC) will focus on the energy industry’s low-carbon future.

The Energy Transition Pavilion will showcase technological advances in alternative energy, including efforts to promote energy decarbonization and sustainability. OTC describes the pavilion as a “go-to meeting place for conversation and dialogue around the energy transition.”

“OTC is widely recognized as a central hub for energy professionals and industry thought leaders to collaborate and develop solutions for the energy challenges surfacing this generation and [the] next,” Paul Jones, chairman of OTC, says in a news release. “The addition of the Energy Transition Pavilion enables us to bring together cutting-edge technologies and offshore industry expertise that combined can develop the innovative solutions required to deliver the global transition to a low-carbon economy.”

Jones is principal of Houston-based Lockbridge Energy, a consulting firm that serves the energy industry.

The 2022 conference will take place May 2-5 at Houston’s NRG Park. It’ll be the first fully in-person conference since 2019. Last year’s conference, held in August, was a blend of virtual and in-person activities due to the COVID-19 pandemic. The 2020 conference was canceled.

Presenting sponsors of the pavilion are:

Tier One sponsors are TechnipFMC and Wartsila North America, and Tier Two sponsors are Hiber and the University of Houston’s energy initiative.

Among the events at the pavilion will be a panel discussion 9:45-11 am May 3 that will explore whether there’s space for oil and gas in a low-carbon environment.

Members of the panel will be:
