Decarburization society needed in the process of large capacity storage battery ~ in order to speed up the further popularization of renewable energy

In 2021, "the 26th session of the UN conference on climate change" (COP26) was held in Glasgow.The Paris agreement signed in 2015, long-term goal is to the global average temperature rise during the period of the previous industrialization controlled within 2 ℃, and try to limit temperature rise within 1.5 ℃, while the conference declaration will be "best", and the global targets substantial strengthening for "must limit within 1.5 ℃.To achieve this goal, has gradually formed the international consensus "decarburization" essential, namely have to substantial in 2050 to achieve zero emissions of greenhouse gases.In the process of decarbonization society, is very effective to minimize the use of fossil fuels.Therefore, must further introduction of renewable energy including solar and wind.

But now there are still a lot of topics.Renewable energy depends on natural phenomena to generate power, so we can not control output according to demand.Surplus electricity or take place in a short time, will lead to frequency fluctuation, difficult to achieve a stable power supply.People to make up for the shortcomings, to give hope to the "storage battery".Sumitomo electric from about 40 years ago began to develop large-scale energy storage battery.The original purpose is to achieve "due to factors such as time and different power load" stabilisation, but under the background of global constantly introduce renewable energy, as the electric power system steady state countermeasures, group began promoting large capacity storage battery "all vanadium flow batteries" development, and in April 2022 formally apply in Hokkaido electric co., LTD.Then for large-scale empirical career in California, slowly but surely the results.This will play a supporting role is introduced in the field of renewable energy in the energy storage battery "all vanadium flow batteries" as a whole.
