There is now news that Texas will build a large photovoltaic plant, energy storage, and grid-supported off-grid switching project to power a large data center server. The planned photovoltaic part is 600,000 kW, and the energy storage part is 4 million KWH, which is scheduled to be implemented in phases from 2021 to 2025, while the energy storage part of 4 million KWH will all use Narada power's lead-carbon batteries. In the world of electrochemical energy storage power stations, lithium-ion batteries account for about 90%, with absolute advantages, and Tesla's high-profile involvement in the field of energy storage, but some people in the United States choose lead-carbon batteries, its significance is worth analyzing.
Here is the content list:
Why lead-carbon batteries？
Advantages of lead-carbon batteries in scale energy storage
Lead-carbon batteries should be the first choice for large-scale storage
Although lithium-ion batteries are widely used in chemical energy storage power stations all over the world, combustion and explosion of lithium-ion battery energy storage power stations often occur. For safety reasons, some of those who had previously touted lithium-ion batteries for large-scale storage were skeptical or ambivalent. The Texas project, with its unusual use of lead-carbon batteries that had been neglected for several years, appears to have put safety first.
It is necessary to re-understand the advantages of lead-carbon batteries in large-scale energy storage through the above projects. First, high security. Lead carbon battery has no inflammable substance, which is the basis to ensure high safety. In the past, lead-acid batteries exploded when they electrolyzed water at high voltage and accumulated hydrogen and oxygen. Now lead-carbon batteries have properly solved this hidden danger. Second, large scale. The four million kilowatt-hour power storage stations provide an average of 167 thousand kilowatts of power to the data center for 24 hours. If the power supply is adjusted to 4 hours, the power is 1 million kilowatts, which is a typical scale of a pumped storage power plant. This is a direct challenge to the argument that "chemical power storage scale is not big". Third, new uses. In the era of big data, data centers are mushrooming and consume a lot of power. The combined power supply between light and storage is particularly suitable for this stable load. Four is green. After the completion of the microgrid will get rid of the dependence on the power grid, independent operation. This is an important step towards low-carbon and green energy. Fifth, the price is not high. Its energy conversion efficiency is at least 10 percentage points higher than pumped storage, which is beneficial to improve economic efficiency.
The author believes that the lead-carbon battery is mainly in the lead-acid battery cathode with special activated carbon (or special porous carbon, which is also the origin of the word "carbon" in the lead-carbon battery), solved the sulfate problem (that is, lead sulfate crystal particles grow up and lose the reversibility of charge and discharge) so that the battery life is extended several times. In addition to the original safety, cheapness, ease to recycle, and other advantages, lead carbon batteries should be the first choice for large-scale energy storage. Now the United States is re-using lead-carbon batteries for safety reasons, and it is believed that more enterprises will join in the use of lead-carbon batteries, and the production of lead-carbon batteries will return to the normal development track.
