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.

Rice University opens biotech venture studio in TMC

rapidly scaling

In its mission to amplify and advance biotech innovation, Rice University has announced its latest initiative — a new lab focused on bringing life-saving medical technologies to commercialization.

Established to rapidly build companies based on Rice University's portfolio of over 100 patents, RBL LLC is a new biotech venture creation studio based in Texas Medical Center Helix Park. RBL comes on the heels of establishing the Rice Biotech Launch Pad, a biotech innovation accelerator that opened last year.

Paul Wotton, executive director of the Rice Biotech Launch Pad, co-founded RBL with his colleagues Omid Veiseh, Rice professor of bioengineering and faculty director of the Rice Biotech Launch Pad; Jacob Robinson, Rice professor of electrical and computer engineering; and Dr. Rima Chakrabarti, a physician scientist and venture capital investor with KdT Ventures.

“This is a pivotal moment for Houston and beyond,” Wotton, who serves as RBL’s managing partner, says in a news release from Rice. “Houston has rapidly emerged as a global life sciences powerhouse, blending cutting-edge research with early clinical applications at Rice and the city’s world-renowned hospital systems.

"Investors from across the nation are recognizing Houston’s potential, and with RBL, we’re building on that momentum," he continues. "We’ll not only amplify the work of the Rice Biotech Launch Pad but expand our reach across Texas, creating opportunities for biotech ventures statewide and driving growth for the biotech industry as a whole.”

Strategically located in TMC, RBL will collaborate with medical leaders, investors, corporations, and other players both in the same building and on the greater TMC campus.

“Leveraging Rice University’s Biotech Launch Pad breakthroughs and pairing it with the world-class translational infrastructure of TMC Helix Park well positions RBL to drive unprecedented advances in patient care,” William McKeon, president and CEO of the TMC, says in the release. “This partnership between academia, industry and health care is exactly what’s needed to transform medical discoveries into real-world solutions that improve lives globally.”

RBL is Rice's latest effort to bridge the gap between academia and biotech innovation, an effort led by Paul Cherukuri, Rice’s chief innovation officer, who reportedly spearheaded development of the new initiative.

“RBL is a game-changer for Rice, Houston and the global biotech community,” Cherukuri adds. “This venture not only accelerates the commercialization of our innovations but also sets a blueprint for other universities looking to maximize the real-world impact of their discoveries. By combining scientific expertise with entrepreneurial support from Day Zero together with strategic clinical partnerships in the TMC, we’re creating a model for driving large-scale biotech innovation that universities everywhere should aspire to replicate.”

Since the Rice Biotech Launch Pad was established, Motif Neurotech closed its series A round with an oversubscribed $18.75 million, the hub secured a $34.9 million grant, and a “living pharmacy” founded at the Launch Pad received industry validation.

“RBL provides a powerful platform to translate high-impact scientific discoveries into therapies that will dramatically improve patient outcomes,” Veiseh says. “Our goal is to rapidly bring Rice’s pioneering research into the clinic, delivering life-saving solutions to patients around the world.”

Expert: How to best repurpose Houston’s infrastructure for a clean energy future

guest column

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.
