Tesla’s CTO envisions a future in which low cost batteries change everything #Auspol

The cost of lithium-ion batteries will quickly plummet, and that will transform transportation and electricity use, says JB Straubel.
Tesla’s CTO JB Straubel predicts that low cost batteries will transform transportation and access to electricity over the next decade. In a wide ranging talk at a solar conference in San Francisco Monday night, Straubel described a future in which all vehicles (other than planes and rockets) are powered by batteries, and new electricity systems are built with solar panels combined with batteries.
While less prominent than Tesla’s high profile CEO Elon Musk, Straubel is considered one of the company’s co-founders and is a key inventor of the company’s battery pack technology. Straubel is also one of the core executives working on Tesla’s massive battery factory, which is under construction outside Reno and is supposed to produce enough batteries for 500,000 electric cars annually by 2020.
While the cost of lithium-ion batteries has dropped in recent years, Straubel said that the price will continue to decline dramatically — and he thinks it will happen much more quickly than most people think. These batteries are just at the beginning, or at “the cliff,” of even lower prices, said Straubel.
When it becomes cheaper to drive on battery energy than it is to drive on gasoline, electric vehicles will dominate world transportation, predicted Straubel. Likewise, he said, when the combination of batteries and solar panels become cheap enough to provide electricity for less than the cost of fossil fuel power, solar energy will become the low cost choice.
“Once we get to that there is no going back. That’s the tipping point that’s going to happen, I am quite certain, over the next 10 years,” said Straubel.
Straubel has long proclaimed much more aggressive declines in cost for lithium ion batteries than most executives have in the consumer electronics, auto and energy industries. When Straubel first met Musk, he was busy trying to build a lithium-ion battery pack for a car that could last 1,000 miles.
Over a decade after Musk and Straubel’s first meeting, Tesla is now far closer to that goal as well as the duo’s over arching vision of transforming the way energy is generated and consumed. In April, after close to five years of research and testing, Tesla launched a new division focused on building batteries for the power grid and buildings, which the company calls “Tesla Energy.”

In the months since the launch of the new products, the demand for Tesla batteries by utilities and businesses has been massive, according to Musk. During his talk at the solar conference, Straubel called Tesla Energy a “turning point” for what Tesla represents and the products that Tesla will sell.
But launching the division was a natural evolution for Tesla, from Straubel’s perspective. With just roughly 60,000 battery-filled cars on the roads, Tesla already has 5 gigawatt hours worth of batteries deployed and connecting to the power grid when the cars charge, said Staubel.
If that doesn’t sounds like a lot, that’s already far more than all of the batteries that are currently connected to the power grid providing storage for utilities, businesses and homes, Straubel pointed out. For comparison’s sake, Tesla recently disclosed a large deal with startup Advanced Microgrid Solutions to deploy 500 megawatt hours of batteries that would be the equivalent of installing tens of thousands of its Powerwall home batteries (1,000 megawatts equal 1 gigawatt).
Eventually if and when Tesla TSLA 1.33% has 1 million cars on the roads, the company will have 70 gigawatt hours of energy storage out there plugging into the power grid. The energy charging and discharging of those cars would be about 10 gigawatts of charging that could be controlled using software, said Straubel.
