The hottest power energy storage technology has gr

  • Detail

On July 5, according to singularityhub, renewable energy technology has made great progress in the past few decades, and finally solar and wind power generation can compete with fossil fuels in price. But when the sun is not bright or the wind is no longer blowing, they will not work. Ted, CEO of form energy, a new energy storage company stripped from MIT ˙ Ted Wiley said, "if we want to use renewable energy to power the world, we need to find a way to overcome this variability, so that we can get energy when we need it."

this means using batteries to store excess energy to make up for changes in supply. These batteries can store energy not only daily, but also for weeks or even months. Form energy is particularly concerned about battery technology with long energy storage time. The company is designing a new battery based on sulfur, which can store renewable energy for several months at a time, and the cost is only a small part of the current cost. Bill ˙ Bill Gates, Jeff ˙ Jeff Bezos, Jack Ma, and Richard ˙ Billionaires such as rid Branson have invested in it

although the cost of lithium-ion batteries has fallen sharply in the past decade, their cost, including Solvay's carbon fiber materials, is still too high to cover a longer service life, making renewable energy the main energy of our electricity. For this reason, MIT professor and co-founder of form energy confirmed that one of the solutions that the company is seeking is "sulfur flow battery". Willie, CEO of form energy, previously co founded the battery startup company aquon energy and was funded by gates. Willie admitted: "if the sulfur flow battery idea succeeds, it may completely redefine the power industry."

Jiang Yeming's early experimental results of sulfur battery show that thiolithium can be used to produce rechargeable batteries. Sulfur is a natural by-product of natural gas and oil refining. It is not only rich in reserves, but also excellent in long-term energy storage. He worked with Marco, Ph.D. and energy storage modeling expert of Massachusetts Institute of Technology (MIT) ˙ Marco Ferrara concluded that renewable energy power generation, including this storage technology, can change global energy and completely replace fossil fuels

so far, form energy has been reluctant to disclose specific details about the new technology. Fluid batteries usually consist of two tanks containing some form of electrically active chemical elements. The liquid is pumped through the central charging room containing positive and negative electrodes (anode and cathode), which is also where the energy storage and release process is expected to take place in the trial operation at the end of 2018. The charging chamber is separated into two parts by a thin film to ensure that the liquids do not really contact each other. The advantages of fluid battery include easy expansion and long cycle life. Its disadvantages are low energy density and high component cost

form energy uses cheap and abundant sulfur, which greatly reduces the cost. As described in PV magazine, the battery uses sulfur in the anode and oxygenated liquid salt in the cathode. Oxygen enters and exits the cathode to discharge and charge the battery. Jiang Yeming explained, "this battery can breathe in and out air, but it does not exhale carbon dioxide, but exhale oxygen. The purpose of this is to create a charge balance by absorbing oxygen into and out of the system."

form energy's current battery sample is only as large as a coffee cup. The scalability of fluid batteries means that they can be upgraded to electric level storage capacity. In a paper on this technology published in 2017, Jiang Yeming said: "the storage chemical cost of fluid batteries is the lowest among known batteries." The cost is as low as $1/kWh. Even with the cost of the edge system, the total cost of the battery may be as low as $10/kWh, which is about one tenth of the cost of the lithium-ion battery, the most advanced material with large elongation, currently used

storage is rapidly becoming the "Holy Grail" of renewable energy. The intermittent production of renewable energy (when the sun is full or the wind is strong, the energy is higher, and vice versa) makes it imperative to find ways to store energy. It is not only stored for a day or two, but seasonal production will also change greatly with the passage of time. Other technologies, such as pumped storage and compressed air storage, currently have a minimum cost of $100/kWh, but geographical factors have seriously affected their potential. If Elon ˙ Elon Musk is right. Lithium ion batteries are also rapidly approaching this benchmark, but these batteries still have certain limitations in energy storage capacity

so far, form energy has raised $11million, including $9million from breakthrough energy company (Bev), which was founded by the above-mentioned technology giant. The goal of this US $1billion venture capital fund is that Goldilocks is the world's most diverse new material enterprise, which invests in technologies to combat climate change. Bev said on the website: "our goal is to create financial returns for our investment, and each investment is likely to significantly reduce greenhouse gas emissions. We know that doing so requires creativity and flexibility, and we are eager to help develop future energy solutions in novel ways."

other members of BEV include George ˙ George Soros, mark ˙ Mark Zuckerberg, Masayoshi son, and Michael ˙ Michael Bloomberg. So far, the fund has invested in form energy and quidnet energy, another energy storage startup. If the fund can maintain this investment speed, it will further promote the development of renewable energy. At present, the biggest bottleneck of renewable energy development is storage. With the continuous innovation and progress of battery technology, it is only a matter of time before we can store more solar energy and wind energy
