Batteries you can buy today. Solar that bends. A Japanese plant that makes power from salt water. Small nuclear plants going up. Beaming power from space. And fusion that still isn’t on the grid. Here’s what’s real — and what isn’t.
California power bills are among the highest in the country. In the North State, we feel that every summer: hot days, fire shutdowns, and a grid that was never built for all the new electric cars and air conditioners.
Labs have been promising cheaper, cleaner power for years. Some of that work is finally showing up as real products. A lot of it is still a press release.
Here are six big ideas, ranked from closest to store shelves and job sites to furthest away. The test is simple. Can you buy it? Is someone building it? Or is it still just a test?
The short version
# | What it is | Where it stands |
1 | Better EV batteries | In cars now. Faster charging. Some use salt instead of lithium. |
2 | Thin, bendable solar | Some products for sale. Printed solar is close, but not a normal roof yet. |
3 | Saltwater power | A plant in Japan has been making power since August 2025. Small, but real. |
4 | Small nuclear plants | One old U.S. plant came back online. New small plants are being built. Power late this decade. |
5 | Solar from space | A satellite sent a microwave beam to Earth. Useful power is still years off. |
6 | Fusion | The science works in short bursts. No fusion plant is selling electricity yet. |
Dates slip. Believe a power meter, not a slide deck.
1. Better batteries — you can buy these now
If the test is “can a regular person buy it?”, batteries win. Today’s lithium car batteries cost a fraction of what they did ten years ago. That is why so many new cars are electric. The new news is speed and a backup plan if lithium gets tight.
Chinese battery giants CATL and BYD are selling packs that charge in about 6 or 7 minutes. They use a safer mix called LFP — lithium iron phosphate. It does not like to catch fire the way some older packs did.
They are also selling sodium batteries. Sodium is plain salt, more or less. It is cheap and common. These packs do not store quite as much energy, so they fit best in city cars and work trucks. They also keep working in hard cold. First passenger cars with sodium packs are hitting the road in 2026.
Some Chinese cars already use “semi-solid” packs that hold more energy and charge fast. The big prize everyone talks about is a full solid-state battery — no liquid inside, longer range, safer. Toyota and Nissan say late this decade. Mercedes has been road-testing cells from a U.S. company. Treat those claims with care until more cars are on the lot.
Bottom line: if you want a better battery this year, buy the car that exists. Do not wait for the miracle pack on a poster.
2. Thin solar that bends — and solar you can print
Big glass solar farms already work. The new trick is making panels that are light, thin, and can stick to a curved roof, a truck, or even a plane.
Chinese maker LONGi built a silicon cell thinner than a human hair that still turns more than 26 percent of sunlight into power. Other labs stacked two kinds of solar material on a thin wafer and hit about 30 percent. A U.S. company, SolarWindow, is selling a peel-and-stick sheet less than a millimeter thick for factories that build vehicles and buildings.
Another path is printing solar the way you print a newspaper. New “perovskite” inks can be laid down with screens or rollers. Lab cells now beat 22 percent. Some printed modules clear 20 percent. That is getting close to cheap, everyday silicon.
What you cannot buy yet is a printed solar roof with a 25-year warranty that a Shasta County inspector and a bank will both like. The films still have to prove they last in heat, rain, and sun. Thin silicon and special films are for sale. A printed roof for a house in Palo Cedro is still a few years out.
3. Power from salt water — a real plant, a small one
In August 2025, the city of Fukuoka, Japan, turned on a new kind of power plant. It does not use wind, sun, or fuel. It uses the pull between fresh water and very salty water.
On one side of a special filter is cleaned sewage water. On the other side is leftover brine from a plant that turns seawater into drinking water. That brine is about twice as salty as the ocean. Fresh water tries to push through the filter. That push spins a turbine.
The plant makes about 110 kilowatts. Over a year that is enough for roughly 220 to 300 Japanese homes, plus some of the desalting plant’s own power. It runs day and night, rain or shine.
This is not going to replace Shasta Dam. It is a small plant next to a water factory. The smart part is using two waste streams that used to be dumped. The builders spent 20 years making the filters last. They want the next plants to be five to ten times bigger.
California talks about desalting ocean water every drought. If the state ever builds more of those plants, this design could make the leftover brine pay some of the electric bill.
4. Small nuclear plants — steel in the ground
Nuclear fission is the old kind of nuclear: splitting atoms, not fusing them. It is the only item on this list that utilities already know how to plug into the grid for decades at a time.
What is new is size. Instead of a giant plant that takes 15 years and blows the budget, companies are building smaller reactors that can be made in a factory and hauled to the site.
In Michigan, Holtec brought the Palisades plant back from the dead — the first U.S. reactor to restart after it had been shut down for good. In China, a small land plant called Linglong One is finishing tests and may be the first of its kind to sell power. In the United States, Kairos is building a salt-cooled test plant in Tennessee with a deal to sell power to Google. TerraPower broke ground on a sodium-cooled plant in Wyoming. The Tennessee Valley Authority filed to build a GE Hitachi small reactor. The Army picked firms to put tiny reactors on bases.
Do not expect cheap power in Redding from these plants in 2026. First-of-a-kind projects run late and over cost. Honest timing for new U.S. small plants is late this decade into the early 2030s.
The simple point: if California wants power at night and in winter that does not depend on how full Shasta Lake is, nuclear is the option that already has rules, fuel, and construction sites.
5. Solar power from space — the beam works, the bill doesn’t
The idea is straight out of a 1970s magazine. Put solar panels in space, where the sun always shines. Turn that power into a microwave beam. Catch the beam on the ground with a big antenna and feed the grid, day and night.
For years that was talk. Then Caltech flew a small test satellite. In 2023, it sent power from one part of the craft to another — the first wireless power transfer in space. It also pointed the beam at Earth. A station in Pasadena picked up the signal. The power was tiny. The point was to prove the beam could be aimed.
Japan is trying the next step. A washing-machine-sized satellite called OHISAMA is built to send a weak microwave beam from about 280 miles up and light a single LED on the ground. That would be the first time space solar did useful work on Earth. A 2024 test from a fast jet already sent a beam five to seven miles. China has a tall test tower that sent more than a kilowatt across a football field and hit more than one moving target at once.
Some papers say space solar could one day cost under a dime a kilowatt-hour. That only works if rockets get much cheaper and huge satellites can be built in orbit. Space solar is real science. It is not a 2026 power plant.
6. Fusion — the sun in a bottle, still in the lab
Fusion is the opposite of today’s nuclear plants. Instead of splitting heavy atoms, it slams light atoms together, the way the sun does. No long-lived waste like a fission plant. No fuel that runs out in a few decades.
The science finally crossed a line. In 2022, the National Ignition Facility in California used lasers to get more fusion energy out of a fuel pellet than the lasers put into that pellet. By 2025, they could do it again and again. That sounds like a win. It isn’t a power plant. The building that runs those lasers still uses far more electricity than the shot creates.
Other machines hold hot gas with magnets. Germany’s Wendelstein 7-X kept a strong fusion “score” for 43 seconds in 2025. China and France held hot plasma for 15 to 22 minutes. Those are important tests. They are not spinning a turbine for a customer.
Private companies have raised more than $11 billion. The one to watch is Commonwealth Fusion Systems in Massachusetts. Their SPARC machine uses very strong new magnets so it can be much smaller than the giant ITER project in France. SPARC was about 80 percent built in late summer 2026. They hope to turn it on late this year or next, and to get more fusion energy out than they put in during 2027. A bigger plant in Virginia is planned for the early 2030s. Google already said it would buy 200 megawatts if it works.
Helion started building a plant in Washington state. Microsoft signed up for 50 megawatts by 2028. That date is the boldest claim in the business. Many people in the field think it will slip.
Government roadmaps still say the mid-2030s for the first real fusion electricity, and the 2040s before you see a string of plants. Fusion belongs in the conversation. It does not belong in next year’s power-bill plan.
What this means here
Shasta County already makes clean, steady power the old way: water falling through the dam. Nothing on this list replaces that.
What these inventions decide is whether California can keep adding load — cars, heat pumps, computer centers — without turning every dry year into a rate shock.
Batteries and thin solar are the pieces a rancher, a fleet shop, or a small business can actually buy this year. Saltwater power is a reminder that not every new source has to wait on the weather. Small nuclear plants are the only option here that can sit on one site and run for 60 years. Power from space and fusion are national projects. They will not cut a PG&E bill in Redding before the 2030s, if then.
Watch the concrete, the purchase orders, and the hookups to the grid. That is when a “breakthrough” stops being a story and starts being a plant.
