Milestones Reached in Battery, Safer Nuclear Development Using Salt
August 7, 2026 — Breakthroughs in the improvement of batteries for storage of electricity have been elusive, even as pressure from rapidly-expanding electricity demand has positioned batteries as a crucial addition to grids in the U.S., Europe and Asia.
Coupled with the latest developments in molten-salt reactors that cannot experience the feared classical meltdown, which allows them to be considered as much safer than what we think of as nuclear power centers, there is new hope for generating and storing cleaner electricity.
In just the past few days, the Energy Information Agency, the Wall Street Journal, and Oil Price have reported highly encouraging news indicating that the future of battery technology is arriving today.
This is in addition to the EIA’s documentation that, overall, the annual average growth rate of batteries in grid use is 70%.

“After decades of decline and public distrust, the domestic nuclear energy sector is set to bounce back as the technology finds favor among the public and policymakers alike for its ability to provide round-the-clock clean energy. At a time when data center hyperscalers are driving up energy insecurity and climate deadlines are drawing ever closer, the nuclear option is looking better and better. And not only is the United States trying to kickstart the expansion of traditional nuclear energy, it’s also trying to establish a place at the vanguard of next-gen nuclear energy technologies.
“Just this month, in a historic first, the Department of Energy approved a Nuclear Safety Design Agreement for a demonstration molten salt reactor currently under development by Natura Resources at Abilene Christian University in Abilene, Texas. Molten salt reactors (MSRs) are emerging as one of the leading potential technologies that could someday take over the global nuclear power sector, as they may be able to solve or sidestep many of the pitfalls associated with traditional nuclear energy.
“MSRs are designed to use less fuel and produce shorter-lived radioactive waste than other reactor types,” describes the United States Department of Energy. “They have the potential to significantly change the safety posture and economics of nuclear energy production by processing fuel online, removing waste products and adding fresh fuel without lengthy refueling outages.” In other words, MSRs are cheaper and safer than a standard nuclear fission reactor.” — See more on this story from Oil Price
A Milestone For Sodium-Ion Cells
As The Wall Street Journal reports, “U.S. startups are finally delivering something researchers have been working on for decades: a battery in which rare, hard-to-get elements are replaced with the same stuff found in ordinary table salt.
“This tech has the potential to help every country on earth break its dependence on China for batteries, and the critical minerals that go into them.
“Like any other battery, sodium-ion cells can store and release energy. They are initially being deployed where they’re needed most, in America’s power grid and fast-expanding crop of data centers. As in our homes, giving the grid or other infrastructure the ability to stockpile energy when it is cheap and plentiful, and discharge it when it is scarce, can increase reliability and lower the cost of electricity.
“While grid battery storage is already growing in the U.S. at a furious pace, new sodium-based batteries are potentially cheaper, longer-lasting, safer and more reliable than conventional, lithium-based ones. They could accelerate the rollout of renewables, and be part of less-polluting alternatives to natural-gas turbines and diesel generators.
Most sodium-based batteries are now made in China, and represent less than 1% of all batteries delivered this year. In the U.S., a number of startups have begun producing small numbers of such batteries, and are racing to scale up production. One industrial giant—General Motors —is in the process of designing its own sodium-based batteries to tailor them to different applications before moving to mass production.

And the U.S. Energy Information Administration reports utility-scale battery storage capacity in the United States increased significantly during the last three years, with an annual average growth rate of 70%. By the end of 2025, the U.S. power system had operational battery storage capacity of 43.6 gigawatts (GW).
During the first six months of 2026, operators added another 8.3 GW of battery storage capacity, reaching nearly 52 GW of nameplate battery storage capacity, based on our latest Preliminary Monthly Electric Generator Inventory.
Operators anticipate bringing an additional 54 GW of battery storage capacity online over the next two and half years, according to plans they report to us. Plans for additional capacity coming online in the second half of this year total 14 GW. Operators currently plan to add 26 GW in 2027 and 14 GW in 2028.
Solar photovoltaic (PV) plants host the largest battery storage capacity units. The Bellefield Solar and Energy Storage Farm, which began operations in December 2025, couples 500 megawatts (MW) of photovoltaic capacity with 500 MW of nameplate power storage for the California Independent System Operator (CAISO).
Plans for the Bellefield facility call for a doubling of the PV and storage capacity of the facility and for the new capacity to be operational by November this year. If those plans materialize, the facility will become the largest power storage facility in the United States.
The Manatee Solar Energy Center in Florida, operational since 2021, has 75 MW of solar capacity and 409 MW of battery storage capacity; it is the second-largest battery storage project. The Gemini Solar Hybrid in the state of Nevada has 690 MW of photovoltaic capacity along with power storage capacity of 380 MW, which became operational in 2024.
