A research lab at the University of Houston has developed a new type of material for sodium-ion batteries that could make them more efficient and boost their energy performance.

Led by Pieremanuele Canepa, Robert Welch assistant professor of electrical and computer engineering at UH, the Canepa Research Laboratory is working on a new material called sodium vanadium phosphate, which improves sodium-ion battery performance by increasing the energy density.

The Canepa Lab used theoretical expertise and computational methods to discover new materials and molecules to help advance clean energy technologies. Continue reading.

Texas A&M University in College Station has received a nearly $1.3 million federal grant for development of clean energy technology.

The university will use the $1,280,553 grant from the U.S. Department of Energy to develop a cost-effective, sustainable method for extracting rare earth elements from electronic waste.

The grant awarded to Texas A&M was among $17 million in DOE grants given to 14 projects that seek to accelerate innovation in the critical materials sector. Continue reading.

Houston-based manufacturer of high-temperature superconducting wires MetOx International Inc. will build a major production facility in Chatham County, North Carolina, which is expected to create 333 jobs, and invest $193.7 million in the state.

MetOx is a leader in High Temperature Superconducting technology (HTS), which is an advanced power delivery technology that is capable of transmitting extremely high power at low voltage with zero heat generation or energy loss. The technology is assisting in the energy sectors like power transmission, distribution, and grid expansion. Continue reading.

5. DOE taps Texas and Louisiana organizations for new clean energy consortium

The U.S. Department of Energy (DOE) has chosen nine participants for the new Regional Energy Democracy Initiative (REDI), a consortium that will help guide clean energy projects in Texas and Louisiana.

“REDI’s pilot program will help ensure that communities in Texas and Louisiana — states that are poised to receive over $8 billion for carbon reduction and clean energy infrastructure projects — have the resources they need to help steer the historic clean energy investments in their backyards,” Jennifer Granholm, U.S. Energy Secretary, said in a statement.

A View From HETI

Solar barely eclipsed coal to become the third biggest source of energy generated for the Electric Reliability Council of Texas (ERCOT) in 2025, according to new data.

In 2024, solar represented 10 percent of energy supplied to the ERCOT electric grid. Last year, that number climbed to 14 percent. During the same period, coal’s share remained at 13 percent.

From the largest to smallest share, here’s the breakdown of other ERCOT energy sources in 2025 compared with 2024:

  • Combined-cycle gas: 33 percent, down from 35 percent in 2024
  • Wind: 23 percent, down from 24 percent in 2024
  • Natural gas: 8 percent, down from 9 percent in 2024
  • Nuclear: 8 percent, unchanged from 2024
  • Other sources: 1 percent, unchanged from 2024

Combined, solar and wind accounted for 37 percent of ERCOT energy sources.

Looking ahead, solar promises to reign as the star of the ERCOT show:

  • An ERCOT report released in December 2024 said solar is on track to continue outpacing other energy sources in terms of growth of installed generating capacity, followed by battery energy storage.
  • In December, ERCOT reported that more than 11,100 megawatts of new generating capacity had been added to its grid since the previous winter. One megawatt of electricity serves about 250 homes in peak-demand periods. Battery energy storage made up 47 percent of the new capacity, with solar in second place at 40 percent.

The mix of ERCOT’s energy is critical to Texas’ growing need for electricity, as ERCOT manages about 90 percent of the electric load for the state, including the Houston metro area. Data centers, AI and population growth are driving heightened demand for electricity.

In the first nine months of 2025, Texas added a nation-leading 7.4 gigawatts of solar capacity, according to a report from data and analytics firm Wood Mackenzie and the Solar Energy Industries Association.

“Remarkable growth in Texas, Indiana, Utah and other states ... shows just how decisively the market is moving toward solar,” says Abigail Ross Hopper, president and CEO of the solar association.
