where is the energy storage battery?
“ &rdquo star; fall, the storage industry at bay
in any sense, aquin energy seems destined to succeed.
the emerging start-up companies to renewable energy projects and power sale of large capacity storage battery by jay whitacre (jay whitacre) was founded in 2007, he is a materials science professor at the carnegie mellon university, once for the nasa mars rover developed a battery. aquin gates, from energy companies including bill, kpcb (kleiner perkins) and shell's venture capitalists and other well-known investors to raise nearly $200 million. perhaps most of all, the company has become acutely aware of the biggest problems of battery project startups before they enter the market; — — it is difficult to avoid the use of rare materials. a warning, aquin energy, more dependent on the use has changed the original production equipment, and to determine the possible direction of market profit.
however, after aquin energy failed to raise more money in march 8th, the company filed for bankruptcy protection, cutting down 80% of its employees and no longer manufacturing. this is the energy storage equipment venture capital company recently suffered another hit. earlier, enervault, a company that produces liquid - based batteries, sold the company after failing to find more investors in 2015. later that year, ambri, a start-up company that produces liquid metal batteries, cut 1/4 jobs. at about the same time, efforts to develop new technology, is committed to energy stored in compressed air in the carbon fiber storage tank in the middle of the lightsail energy company, its products sold to the container turned to natural gas suppliers. in short, the struggle has lowered expectations for the right, functional, and networked storage devices that have recently come to light.
this is a big problem. if there is no cheap way to store the extra energy produced by intermittent energy such as wind or solar energy, these renewable energy sources will limit the power supply of the entire grid. furthermore, its role in slowing the greenhouse effect caused by carbon emissions is open to question. solar farms in california have been closed for a few days, because they generate electricity at a specific time beyond the power grid. however, when the sun is blocked by clouds, the system needs to start up standby equipment to burn enough fossil fuel to meet actual demand.
a year ago, aquin energy ranked fifth among the 50 most intelligent companies in the mit technology review. now it was hard to tell exactly where is the problem, because the extra details provided in the application for bankruptcy is limited, but whitacre has refused to make a speech at the auction is completed, but he made it clear that the company hopes or technology in some form to continue thereafter.
lithium ion battery costs all the way down
in 2012, when the "mit technology review magazine" reported for the first time when aquin company, the company said that they want to be able to manufacture per kwh capacity cost less than $300 battery products. the technology uses brine electrolytes, manganese oxide cathodes, and carbon based anodes to form batteries. the product is priced between low-end lead-acid batteries and more expensive lithium-ion technology. but the main point is that batteries can last longer and perform better in power grid charging and discharging cycles. this could reduce the lifetime cost of the system to a lower level.
we don't know when aquin filed for bankruptcy in the company, their products cost what geometry, but according to peng boxin (bloomberg new energy finance energy finance) reported that the lithium-ion battery in the last year has been below $300 per kwh this cost threshold. in particular, the price fell by half in just two years, reaching only $273 in 2016. this is because, in order to meet the growing demand for mobiles phoness, electric cars and solar power backup systems, the world's lithium battery production has increased gradually. and the price of lithium-ion batteries is likely to continue to decline, bloomberg predicted that in 2025 may be reduced to $109 per kilowatt hour, while in 2030 to reach only 73 u. s.dollars per kilowatt hour.
massachusetts institute of technology (mit) material scientists, ambri's co-founder donald sarkozy multidimensional (sadoway) skeptical, he believed that this estimate represents only a lithium battery energy storage technology in the total cost of the power level. he also believes that the peng boxin energy finance forecast for the future is unrealistic, the 2030 estimate seems to be lower than the cost of raw materials prices. but in any case, the sudden drop in prices has had a huge knock on effect on the energy storage battery market. he said: "&ldquo, when the lithium-ion battery comes on with these bold, surprising speculations, investors stop and look, and say, wow!"you guys are going to be screwed.
at the same time, big clients who are able to consider building multimillion dollar energy storage systems have little incentive to put their weight on new, more risky technologies. “ lithium ion battery has to meet the specific needs of many large utility customers, they can obtain reliable products, from stable supplier ” aes energy department director john zahulanch (john zahurancik) commented to. aes, a power project developer, came in to focus more on battery systems. after the gas leak at the california utility in 2015, they ordered 3 separate lithium-ion systems to replace gas equipment, which was assembled by aes and tesla. “ we think the lithium battery technology is more suitable for this momentand be ready to stand by.
