In a world striving for sustainable and efficient energy solutions, United Kingdom-based LiNa Energy emerges as a promising player in the field of advanced battery technologies.

With a focus on overcoming the limitations of traditional lithium-ion batteries, LiNa Energy — a member of the 2023 cohort for Houston-based incubator, Halliburton Labs — presents a unique chemistry that holds the potential to revolutionize energy storage.

In a recent episode of Energy Tech Startups with Will Tope, chief commercial officer of LiNa Energy, we delve into the key aspects of LiNa Energy's technology, exploring the challenges they seek to address and their plans for commercialization.

Energy Tech Startups: What is the main problem that LiNa Energy is trying to solve with their battery technology?

Will Tope: LiNa Energy is driven by a pressing dilemma in today's storage landscape: the limited efficiency and high costs associated with existing storage technologies. They aim to bridge the gap, providing low-cost, long-duration energy storage solutions that can effectively accommodate the increasing penetration of renewable energy sources in power grids worldwide. By addressing this critical need, LiNa Energy aims to unlock the full potential of low-cost, low-carbon electrons for global energy consumption patterns.

ETS: How does LiNa Energy's battery technology differ from traditional lithium-ion batteries?

WT: LiNa Energy's technology distinguishes itself through its unique chemistry and progressive use of ceramics. By combining a stable sodium-based chemistry, developed in the 1970s, with advancements in ceramics from the fuel cell industry, LiNa Energy maximizes safety, heat management, and energy density. Their battery cells feature thin planar ceramic electrolytes, enabling cost-efficient automated manufacturing and reducing the need for extensive thermal management systems. This streamlined approach offers both enhanced performance and cost-effectiveness.

ETS: What are the commercialization plans and target markets for LiNa Energy?

WT: LiNa Energy strategically targets markets with high solar potential, such as India, where the demand for storage solutions arises due to the growing deployment of renewables and the need to shift energy to peak demand periods. LiNa Energy aims to demonstrate the effectiveness of their systems through pilot projects at distribution scale by the end of the year. Leveraging partnerships and strong relationships with key players in the energy industry, LiNa Energy envisions gradual growth in manufacturing capacity worldwide. By offering competitive pricing, they aim to disrupt the market and drive widespread adoption of their innovative battery technology.

As the energy landscape continues to evolve, LiNa Energy's pursuit of affordable, long-duration energy storage technology stands out as a potential game-changer. With their unique chemistry, ceramic advancements, and focus on commercialization in markets with enormous renewable energy potential, LiNa Energy demonstrates a commitment to addressing the world's energy challenges. By challenging the status quo of traditional energy storage systems, LiNa Energy paves the way for a future where efficient and sustainable energy solutions become the norm.

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.
