UH lands $8M in federal funding for fusion energy research

fusion funding

The University of Houston will receive $8 million in federal funding from the U.S. Department of Energy for its work on fusion technology to help power data centers and medical work.

Venkat Selvamanickam, professor at UH’s Cullen College of Mechanical and Aerospace Engineering and director of the Advanced Manufacturing Institute, has been tasked to lead the research on superconducting magnets that he said will make compact fusion reactors possible.

“Beyond fusion, superconductors can transform how we deliver power to data centers, enable highly efficient motors and generators and improve electric power devices,” Selvamanickam said in a news release. “They also enable critical applications such as MRI and proton beam therapy for cancer treatment. I want society to experience the broad benefits this remarkable technology can provide.”

UH is one of 23 institutions selected to share part of $134 million from the DOE’s Fusion Energy Sciences division. The total funding is split across two initiatives: $128 million for the Fusion Innovation Research Engine (FIRE) and $6.1 million for the Innovation Network for Fusion Energy program, according to the university.

UH will partner with the FIRE Collaborative for the research, which looks to understand why superconducting magnets in fusion reactors break down and work on developing solutions to make them more resilient.

“The advantage of fusion is it’s clean and it does not require storage. Solar energy can’t be used at night, and wind energy depends on wind conditions,” Selvamanickam added in the release. “Our goal is to make fusion a truly viable energy source.”

Energy expert on Houston's advantage: Building affordability and reliability for all

Guest Column

As the energy capital of the world, Houston has been at the forefront of innovation, powering industries and communities for generations. Many Houston families, however, are facing a reality that undermines our leadership: high energy bills and ongoing concerns about grid reliability.

Affordability and reliability are not just technical issues; they’re equity issues. To remain the world leader in energy, we must ensure that every household has access to affordable and dependable power.

Affordability: The First Step Toward Equity

According to the recent 2025 study by The Texas Energy Poverty Research Institute, nearly 80% of low- to moderate-income Houstonians scaled back on basic needs to cover electric bills. Rising costs mean some Houstonians are forced to choose between paying their utility bill or paying for groceries.

Additionally, Houston now has the highest poverty rate among America’s most populous cities. Energy should not be a privilege for only half of our city’s population. That’s why affordability needs to be at the center of Houston’s energy conversation.

Several practical solutions exist to help address this inequity:

  • We can increase transparency in electricity pricing and help families better understand their electricity facts labels to make smarter choices.
  • We can expand energy efficiency programs, like weatherizing homes and apartments, swapping out old light bulbs for LEDs, and adopting smart thermostats.
  • Incentives to help families invest in these changes can deliver long-term benefits for both them and apartment complex owners.

Many small changes, when combined, can add up to significant savings for families while reducing overall demand on the grid.

Reliability: A Shared Community Priority

The memories of Hurricane Beryl, Derecho, and Winter Storm Uri are still fresh in the minds of Texans. We saw firsthand the fragility of our grid and how devastating outages are to families, especially those without resources to handle extreme weather. Reliability of the grid is an issue of public health, economic stability, and community safety.

Houston has an opportunity to lead by embracing innovation. Grid modernization, from deploying microgrids to expanding battery storage, can provide stability when the system is under stress. Partnerships between utilities, businesses, and community organizations are key to building resilience. With Houston’s innovation ecosystem, we can pilot solutions here that other regions will look to replicate.

Energy Equity in Action

Reliable, affordable energy strengthens equity in tangible ways. When households spend less on utilities, they have more to invest in their children’s education or save for the future. When power is stable, schools remain open, businesses continue to operate, and communities thrive. Extending energy efficiency programs across all neighborhoods creates a fairer, more balanced system, breaking down inequities tied to income and geography.

Studies show that expanding urban green spaces such as community gardens and tree-planting programs can lower neighborhood temperatures, reduce energy use for cooling, and improve air quality in disadvantaged areas, directly reducing household utility burdens.

In Houston, for example, the median energy burden for low-income households is 7.1% of income, more than twice that of the general population, with over 20% of households having energy burdens above 6%.

Research also demonstrates that community solar programs and urban cooling investments deliver clean, affordable power, helping to mitigate heat stress and making them high-impact strategies for energy equity and climate resilience in vulnerable neighborhoods.

Public-Private Partnerships Make the Difference

The solutions to affordability and reliability challenges must come from cross-sector collaboration. For example, CenterPoint Energy offers incentives through its Residential and Hard-to-Reach Programs, which support contractors and community agencies in delivering energy efficiency upgrades, including weatherization, to low-income households in the greater Houston area.

Nonprofits like the Houston Advanced Research Center (HARC) received a $1.9 million Department of Energy grant to lead a weatherization program tailored for underserved communities in Harris County, helping to lower bills and improve housing safety

Meanwhile, the City of Houston’s Green Office Challenge and Better Buildings Initiative bring private-sector sponsors, nonprofits, and city leadership together to drive energy reductions across millions of square feet of commercial buildings, backed by training and financial incentives. Together, these partnerships can result in real impact that brings more equity and access to affordable energy.

BKV Energy is committed to being part of the solution by promoting practical, consumer-focused strategies that help families save money and use energy more efficiently. We offer a suite of programs designed to provide customers with financial benefits and alleviate the burden of rising electricity bills. Programs like BKV Energy’s demonstrate how utilities can ease financial strain for families while building stronger customer loyalty and trust. Expanding similar initiatives across Houston would not only lower household energy burdens but also set a new standard for how energy companies can invest directly in their communities.

By proactively addressing affordability, energy companies can help ensure that rising costs don’t disproportionately impact vulnerable households. These efforts also contribute to a more resilient and equitable energy future for Houston, where all residents can access reliable power without sacrificing financial stability.

Houston as a Blueprint

Houston has always been a city of leadership and innovation, whether pioneering the space race, driving advancements in medical research at the Texas Medical Center, or anchoring the global energy industry. Today, our challenge is just as urgent: affordability and reliability must become the cornerstones of our energy future. Houston has the expertise and the collaborative spirit to show how it can be done.

By scaling innovative solutions, Houston can make energy more equitable, strengthening our own community while setting a blueprint for the nation. As the energy capital of the world, it is both our responsibility and our opportunity to lead the way to a more equitable future for all.
