An Energy Breakthrough Could Store Solar Power for Decades

The system starts with a liquid molecule made up of carbonhydrogen, and nitrogen. When hit by sunlight, the molecule draws in the sun’s energy and holds it until a catalyst triggers its release as heat.

Tesla Energy is Elon Musk’s battery system that can power homes, businesses, and the world

Powerwall is a home battery system, that comes in a 10 kWh version for $3,500, or a 7 kWh model for $3,000. The unit is about three feet by four feet in size and six inches thick, and comes with integrated heat management and  can fit either on the inside or outside of the wall of your home. The system is connected to the internet — Elon Musk said that the system can be used to create “smart microgrids” — and can be used as a redundancy system, or potentially allow a home to go off the power grid entirely.

The company said it has identified a new battery cell that has 31 percent more energy than the cells used in the original Roadster.

On top of that, the Roadster 3.0 is expected to be 15 percent more aerodynamic than the original Roadster, and the new Roadster’s tires will have a 20 percent increase in roll resistance compared to earlier versions.

Answer is in the Wind

“Wind technologies generate far more energy than they consume,” Dale said. “Our study showed that wind actually produces enough surplus electricity to support up to 72 hours of either battery or geologic storage. This suggests that the industry could deploy enough storage to cope with three-day lulls in wind, common to many weather systems, and still provide net electricity to society.”

The results were especially good for onshore wind turbines. “We found that onshore wind backed by three days of geologic storage can support annual growth rates of 100 percent — in other words, double in size each year — and still maintain an energy surplus,” he said.

 

Wind farms can provide society a surplus of reliable clean energy
