The battery is one of the issues we value in our mobile devices and a headache for manufacturers since these are increasingly demanding this level and more compact. But what if in the future of battery power entire cities ?
This approach may sound utopian but it is risky and what is proposed for a city like Los Angeles. And utopian has little since, as we read in Scientific American , it is expected that in five years these giant batteries replace current systems of energy supply towards stop using the combustion gas.
A battery to supply to all
In summer energy demand is always higher because air conditioners and other appliances that turn on mass and long. Making extra resources (including water) that usually occurs especially in the thing, and Los Angeles have used gas plants which operate in summer to provide this energy plus.
In order to be less and less dependent on fossil fuels, which have planned is that instead of gas plants recourse to what would be the world's largest battery , capable of delivering more than 100 megawatts / hour power for four hours (relatively little, although the supply of extra energy is done during the evenings).
The battery would have a solar load that would be active all morning during daylight hours, using the photon substantial portion of the area and be a source of cheaper energy than others (besides clean). The idea is that also serves to provide a second extra dose of energy first morning, in this case wind energy.
The technology is already at a fairly advanced stage after nine years AES Corp., the company's Arlington (Virginia) responsible for designing this megabatería, takes working together with manufacturers of car batteries . A technology that would have served as a reference when assembling and controlling 18,000 lithium battery modules that compose.
The feet on the ground: what about the blackouts?
Not everything is a bed of roses in relation to this project. In addition to the defending voices at the level of cost and clean energy, Haresh Kamath, manager boss at ElectricPower Research Institute (EPRI), recalls incidents that current domestic solar energy systems ( net metering ) when, for example, voltage is very high.
On the other hand, Vince Sprenkle, chief engineer at the Pacific Northwest National Laboratory working on energy storage, says each region will have a distinct patterns when these super batteries. He has a somewhat less optimistic than it will take to have a list of these batteries forecast, noting that in the case of a Pacific Northwest will take about ten years .
The trial and the rush to be clean
The idea, as we said, is that in 2021 we see this large battery to operate and provide the energy that the Californian city asks more on warm summer evenings. But despite the will so be it and hurry to the Public Utilities Commission of California is putting to 2050 greenhouse gas emissions are reduced by 80%, it is quite likely to take more than five years to have the invention ready for use.
The most urgent is the need for energy which gas stations last summer and fell short
And it 's no longer just the "institutional" requirement, the most urgent is the need for energy which gas stations last summer and fell short. The authorities are already warning of possible rolling blackouts that may be due to problems arising from an incident in Porter Ranch Station , which although earlier this year gave the plant is not yet recovered.
However, despite the early system other cities and regions such as London, New York or Chile also this solution arise instead of opting for traditional power plants, which in addition to being non - renewable energy sources in many cases usually involve a more investment. At the moment we are seeing a small scale applications of this as the powerwall Tesla or Orison , a battery of 2.2 to 10 kWh to provide renewable energy at home.
