2018-10-01: Governments from California to China and South Korea -- even Donald Trump's Washington -- have taken steps that will make battery power more ubiquitous. There's just one hitch to this battery boom: The world isn't making nearly enough. All of the new demand from North America, Europe and Asia is constrained at the moment by a market that remains heavily dependent on a few producers. Data on the global supply of batteries is hard to come by, but close observers of the industry have noticed evidence of the shortfall. "We've never seen such demand," said Yayoi Sekine, a New York-based analyst at Bloomberg NEF. "But the supply is struggling to keep up."
Oddly, however, lithium-ion battery-rack prices have continued their annual decline, even in the face of constrained supply and expectations of ever-growing demand. To get a clear sense of the near future, consider battery-powered cars: Today, there are more than 3 million electric vehicles on the road worldwide; by 2025, Volkswagen AG alone plans to build as many as 3 million electric vehicles per year. Those vehicle batteries -- in addition to storage batteries for homes, businesses and utilities -- will have to come from somewhere.
Starting off with updates on the two and three-wheeler inventory and baseline study being carried out, Clean Air Asia Transport Specialist Joemier Pontawe said data from the Land Transportation Office (LTO) showed that of the 5 million vehicles registered in 2002, two and three-wheelers accounted for 43 percent, rising to 60 percent of the total 10 million motor vehicles registered in 2017.
“This reveals a surge in two and three-wheelers within a decade, and it is important to note we only have information on gasoline-powered two and three-wheelers and none yet on electric units that have entered the market,”
2018/09/27: scientists trying to improve the solar cells themselves developed an integrated battery that works in three different ways. It can work like a normal solar cell by converting sunlight to electricity immediately, explains study author Song Jin, a chemist at the University of Wisconsin at Madison. It can store the solar energy, or it can simply be charged like a normal battery. It's a combination of two existing technologies: solar cells that harvest light, and a so-called flow battery.
The most commonly used batteries, lithium-ion, store energy in solid materials, like various metals. Flow batteries, on the other hand, store energy in external liquid tanks. This means they are very easy to scale for large projects. Scaling up all the components of a lithium-ion battery might throw off the engineering, but for flow batteries, "you just make the tank bigger," says Timothy Cook, a University at Buffalo chemist and flow battery expert not involved in the study. "You really simplify how to make the battery grow in capacity," he adds. "We're not making flow batteries to power a cell phone, we're thinking about buildings or industrial sites.
2018/08/18: Energy Vault’s plant can operate for 30 years with little maintenance and almost no fade in capacity. Its concrete blocks also use waste materials. So Piconi is confident that there’s still a niche that Energy Vault can fill: Places that have abundant access to land and building material, combined with the desire to have storage technologies that last for decades without fading in capacity.
Meanwhile, whether or not Energy Vault succeeds, it does make a strong case for the argument that, while everyone else is out looking for high-tech, futuristic battery innovation, there may be real value in thinking about how to apply low-tech solutions to 21st-century problems. Energy Vault built a functional test plant in just nine months, spending relative pennies. It’s a signal of sorts that some of the answers to our energy-storage problems may still be sitting hidden in plain sight.

Perhaps the biggest shortcoming of solar and wind power is their intermittency. In locations like Hawaii, where I live, wind and solar power are already competitive on price. My fossil-fuel supplied electricity typically costs above 40 cents a kilowatt-hour, and wind and solar power can compete with that. But since they can't supply power that is available on demand (firm power) they must be backed up by power sources that can provide power when the sun isn't shining and the wind isn't blowing.
