" The objective of" twin carbon "is what we Chinese should do." Head of State Xi Jinping's essential speech on "dual carbon" was repetitively pointed out by Academician Jinyong. What is the correlation of "dual carbon" with renewable energy and storage?
Hereof, Academician Jin pointed out, "To achieve twin carbon targets, we should not count too much relying on fossil energy, as well as have to depend on wind power and solar energy to renewable energy. China's renewable resource resources develop quite possibly." Open-up resource data shows that in 2022, my country's photovoltaic or pv components in China in 2022 Leave 154.8 GW, an increase of 74% year-on-year. In 2021, the world's leading ten wind power entire maker makers accounted for six seats in my country. For wind power and solar energy, for our country, whether it is resource endowment, technological stamina, or industrial scale, it will not be a "card neck."
" Renewable energy plus (new) energy storage space modern technology is certainly a subversive development technology, which significantly modifies human use power. Fossil energy sources such as coal, oil, and gas have significantly promoted the development of the world's economic situation. Duty. Presently, humans are going into the double carbon period, and non -sustainable, minimal fossil energy resources are slowly being replaced by wind and solar power. "Jin Yong stated.
" With the quick advancement of power storage, modern technology, aviation, railways, and navigation, electrification will gradually become a reality. In 2060, it is anticipated to attain all electrified no-carbon transport." Jin Yong claimed.
Jin Yong stated that the research report released by the International Green Peace Company earlier reveals that the energy offered by solar power is more than 2850 times the existing worldwide energy need, so as long as there are solar centers with excellent performance and low cost, solar energy is theoretically infinite.
Renewable energy, such as solar and wind energy, is significant to China. It is 50% of the world's per capita coal share and 20% of the per capita coal occupation of the United States.
Jin Yong said: "If China does not rely on oil, coal, and gas, nobody can stop us by relying on solar and wind energy. Therefore, renewable energy increases energy storage space innovation is very important to China.
If you intend to create a power system with zero -carbon and no co2 emissions, the lack of key technological web links is power storage. "Because the volatility and interval of wind power and solar energy are strong, but the power grid and customers require a stable power supply, so renewable energy has to be accepted energy storage space to develop a smart grid. Change the fossil energy. "Academician Jinyong claimed.
An undeniable fact is that the development of energy storage space innovation has not settled its shortcomings, and power storage space technology itself is not total. "Currently, the largest energy storage space approach is similar to China or the globe. It is pumping water storage space (standard power storage technology). It is hard to choose the area of the energy station; second, the financial investment price of pumping power stations is reasonably high, getting to 7000 to 8,000 yuan/kW. "
" Currently, the biggest modern technology of (new) energy storage innovation is electrochemical battery energy storage space, while electrochemical energy storage space technology is currently widely used as well as a prominent result. Its benefit, yet big-scale lithium battery power storage, is largely invested, and this trouble has not yet been entirely resolved. Various other energy storage innovations also include physical energy storage space, hydrogen energy storage, warm storage, and so on. In the affordable phase of Baihua, no power storage innovation has been satisfying in terms of economy and security. For China, it is an emerging market worth investing in skill training, technological study, design advancement, and large-range operation. As a result, the power storage space industry is appealing. Your power storage association (power storage application branch) is very beneficial! "
Transportation, industry, and construction are the main make-up of fossil energy usage and the crucial target of minimizing power usage and emissions. Whether renewable energy and power storage space technology can be proactively actively played in the three major energy usage and high emissions markets of sectors, structures, and transport. What regarding it?
In reaction to this problem, Jin Yong stated, "Of course, the steel market can use electrical furnaces to steel for steel; the building and construction sector can utilize geothermal energy, wind energy, solar power as well as another renewable resource to attain self -adequacy in structure power." It is more typical. With your very own solar energy as well as a wind power tool, you can understand the self-sufficiency of electric energy to make sure that the distributed power storage power tool of each family does not require to be power from the Net, and it can also market excess power to the power grid firm. China might accomplish this in particular situations, such as urban vacation home areas and country buildings that can achieve dispersed energy storage. "
According to stats, each new energy automobile has a battery power storage energy storage space of 60 to 100 kWh under normal circumstances. My country's new power automobiles are established quickly, with a guaranteed quantity of 13 million units. New energy automobiles can be used as distributed power storage devices.
Jin Yong said, "The country can introduce standards and policies to unify the energy storage device interface for vehicle power batteries. Sinopec feedback is that the amount of new energy vehicles is too small. "
" With the quick advancement of power storage, modern technology, aviation, railways, and navigation, electrification will gradually become a reality. In 2060, it is anticipated to attain all electrified no-carbon transport." Jin Yong claimed.
The current lithium battery and the future sodium-ion battery technology have quickly improved. The biggest advantage of lithium batteries is how much power to charge them. "Jin Yong said," For a chemist like me, the past, present, and the future are not energy.
The annual output of hydrogen in my country is the world's largest, with an annual output of more than 40 million tons, of which more than 30 million tons are used for synthetic ammonia or chemicals. It is understood that the output of water-based electrolytic hydrogen in my country is very low because the cost is high. Electrolyte hydrogen is very clean, the economy is low, and the electrolytic water hydrogen technology needs further innovation.
Jin Yong pointed out that "hydrogen fuel cells are the chemicals of hydrogen and oxygen into a battery that can be converted into electrical energy. The essence of hydrogen fuel cells is a chemical battery, and the conversion efficiency of hydrogen fuel cells is relatively low. Its energy is only half the original, and the energy conversion rate is only 50%. Without using it, it has lost 50%. The conversion process will lose about 50% of the energy if the vehicle drives. That is to say, turning electricity into hydrogen and then transforming hydrogen into electricity. The entire process will be lost by 75%, and the overall conversion efficiency will not be high. "
Jinyong pointed out that hydrogen fuel cells can be applied under special circumstances, such as heavy-duty vehicles and submarines, but the cost is higher. The high-pressure hydrogen cylinder with hydrogen fuel vehicles exceeds 300 kg, and the hydrogen molecules are too small to spread and penetrate.
Research data show that by 2060, the total energy consumption of my country's energy will be about 2.373 billion to 4.746 billion tons of standard coal, equivalent to 1.9.3 trillion to 38.6 trillion kWh, and the per capita electricity consumption is 13,000 to 26,000-kilowatt hours. Roughly 2.5 to 5 times. Which energy and energy structure can meet my country's large-scale electricity consumption?
Jin Yong believes that renewable energy storage and (controllable) nuclear fusion may be the main solution to future energy to achieve dual carbon targets and meet future electricity needs. Academician Jinyong said that the energy the nuclear aggregation substation provides is sufficient.
Jin Yong pointed out that it is predictable that by 2060, my country's renewable energy increase can meet the total energy demand of 80%, and the rest are natural gas, oil, and coal, accounting for 7.4%, 7.3%, and 1.7%, respectively. At that time, there will still be the value of fossil energy power stations. The premise is that they can flexibly schedule, adjust, and cooperate with renewable energy networking.
In this regard, Academician Jin pointed out, "To achieve dual carbon targets, we must not rely too much on fossil energy, and must rely on wind power and solar energy to renewable energy." Renewable energy plus (new) energy storage technology is a subversive innovation technology, which is a major change in human energy use. "Because the volatility and interval of wind power and solar energy are strong, but the power grid and users need a stable power supply, so renewable energy must be cooperated with energy storage to form a smart grid. Whether renewable energy and energy storage technology can be actively played in the three major energy consumption and high emissions industries of industries, buildings, and transportation, through your own solar energy and wind power device, you can realize the self-sufficiency of electric energy so that the distributed energy storage power device of each household does not need to be electricity from the Internet. It can also sell excess power to the power grid company.
