The global crude oil price storm has not yet been calmed down. It has caused the fiscal deficit of oil-exporting countries to soar; the oil-consuming countries have ushered in opportunities; the new nuclear issue has emerged, and people have once again experienced the enormous energy that can shake the global economy.
In fact, as far as the energy industry is concerned, new technologies can “subvert†the world overnight. Taking the hydraulic fracturing method as an example, it created a “shale revolution†that caused the current oil industry to undergo tremendous changes. Similarly, energy storage technology has great potential to change the development of the global economic situation.
As we all know, solar energy and wind energy are used to generate electricity, and it is not always able to catch up with the peak period of electricity consumption. Therefore, the use of renewable energy has long been plagued by energy storage problems. The key to unlocking the potential of renewable energy lies in energy storage technology. If countries such as Japan and Saudi Arabia, which rely mainly on fossil energy, vigorously reduce oil consumption, switch to solar and wind power generation, and use appropriate energy storage technologies, they can offset the global use of 4 million barrels of crude oil per day. This data is equivalent to 4.5% of global oil consumption, which is equivalent to the increase in oil production caused by the crude oil price storm.
In addition, the energy storage technology shows that the environmental benefits are also very amazing. It allows solar and wind energy to completely replace coal and natural gas. Just as the hydraulic fracturing method is based on the oil industry, the energy storage technology applied to the grid will make a leap in the global economy. Citibank's research shows that the commercial impact of energy storage technology applied to the US power grid by 2030 could add $400 billion in annual taxes to the United States.
Of course, good prospects also need to be complemented by huge investments. Take the electric vehicle as an example, in which the cost of the battery accounts for 1/3 of the total vehicle cost, and the technological innovation will reduce the production cost again and again, and finally make the electric vehicle and the fuel vehicle almost the same. If you calculate the cost of retrofitting a traditional car to meet the exhaust emission standards, the cost of the electric car will be lower. Eddie Technology Consulting expects sales of new electric vehicles to triple by 2024 to 10 million vehicles per year, with sales reaching $1,790 trillion.
When it comes to the market forecast for electric vehicles, just “if†and “possible†will cause many policy commentators and corporate observers to question. Nowadays, China and the United States have made a "gamble" on the prospects of electric vehicles. In the past less than five years, they have invested hundreds of millions of dollars. Both countries have vowed to achieve 1 million by 2015. The feat of an electric car on the road. This goal now seems to be "blowing" in general: as of the end of 2014, China and the United States sold a total of less than 350,000 electric vehicles; the famous Tesla sales data in December 2014 was only 47,000. Car.
For the battery alone, the high production costs and unsatisfactory energy storage efficiency have made people's enthusiasm for renewable energy fall into the bottom. Good prospects need scientific progress to support, and energy storage technology needs government policy support.
Efficient batteryCompared to other major technologies, battery development is quite slow. The first battery was invented in 1800 Watt; in 1859, Plant invented a lead-acid battery, which is still widely used in fuel vehicles; until 1991, Sony produced the first commercial lithium battery.
Nowadays, the problem of "super battery" is still to solve how to safely reciprocate lithium ions in the battery at high speed, and the cost of the battery should be reasonable. Most of the advances in battery development came from manufacturers of commercial batteries and electric vehicle manufacturers. Successful car batteries must overcome several major obstacles: let the car travel farther, make the car faster, the battery life is longer, and never fire, the price is more reasonable.
Modern technology can't meet all of these standards. Tesla seems to satisfy most of them, but the cost is not enough, so it can only occupy the high-end consumer market. This step is impossible to achieve without the support of the government. In 2009, US President Barack Obama promised that from the first day of his appointment to 2015, the United States will receive 40% of the global battery market share. As part of stimulating economic growth, he invested $2.4 billion to develop batteries and electric vehicles. For the past few years, the US Department of Energy has allocated $50 million a year. Obama also gives a $7,500 grant to users who buy electric cars.
Other countries have taken similar measures. France, Norway, Spain and the United Kingdom have also implemented tax exemption policies for the purchase of electric vehicles. South Korea is subsidizing US$13,500 for each electric vehicle purchased. Japan requires half of the electric vehicles in Nissan vehicles by 2020, and all taxes are exempted. paragraph.
Lower the priceThis year, Tohoku Electric Power Co., Ltd. is planning to use the world's largest power storage equipment on the grid. The company is building a 40 MW storage facility in Sanno to store electricity from solar and wind power. The equipment sold by Toshiba is equivalent to $5,000 per kWh, which industry analysts believe is 20 times the price of solar and wind power and traditional power generation. The good news is that large storage facilities for the grid are cutting prices and are expected to reach $230 to $500 per kWh by 2020. At that time, the power storage technology will reach a turning point, and it can compete with coal power and oil and gas power generation on the power grid.
No matter how people are eager for the substantial development of energy storage, global pollution still cannot completely abandon fossil fuel power generation. At present, in Australia, Germany, Italy, Portugal, Spain and the southern United States, solar power has achieved unsubsidized competition, but this is the combination of off-grid electricity and grid purchases. If solar power in these places is equipped with energy storage equipment and is completely dependent on renewable energy, then the cost of electricity will be higher than the grid.
Favhan Consulting predicts that in the next 10 years, Asia will make a big leap in energy storage technology for the grid, thanks to the layout of the infrastructure. The United States is not to be outdone in terms of renewable energy generation and storage. The California government said that by 2022, 1,300 megawatts of storage facilities will be installed. Edison will use the city of Tehachapi as a pilot to install 32 kilowatts of electrical energy storage facilities for 5,000 wind turbines.
Winner and loserIn every energy change, there will be winners and losers. The biggest victim of energy storage technology development is coal power, and oil is another loser. It has also been said that the development of the energy storage market is nothing more than a false phenomenon caused by subsidy policies. ExxonMobil has said that the development prospects of power storage equipment are very bleak. By 2040, renewable energy will still face the troubles of today, that is, batteries are expensive and difficult to connect to the grid. The company asserts that by then, solar, wind and biofuel power generation will only be able to supply less than 4% of the world's total electricity generation, which means that there is little room for energy storage in the grid.
Former US Energy Secretary Zhu Xiwen has publicly stated that public power facilities and fossil fuel power generation will not be able to continue to guarantee the profit model of the power company. He believes that the power plant will soon be replaced by distributed power generation. In 10 years, US residents will pay 10,000 to 12,000 US dollars for power storage equipment, and 80% of the time will exit the grid. This kind of distributed power generation system can generally save 1/4 of the electricity bill paid at the peak of power consumption.
In terms of energy storage technology, electric vehicle manufacturers have always been recognized as having technical advantages, so they will also become the forerunners of large-scale storage and grid connection. To put it simply, Tesla's best-selling model, the OneModelS, has an 85-kilowatt battery capacity that can store enough electricity for an average household for three and a half days. Analysts believe that the battery can be charged when the power is low, and the battery can meet the household electricity consumption when the peak power is used. Morgan Stanley Investment expects that 3.9 million Tesla electric vehicles will be on US roads by 2028. This huge team can charge 8% of American households an hour a day.
Tesla has to take the lead in manufacturing capabilities to meet the demand for grid chargers. They have begun investing $5 billion to build a charger manufacturing facility near Reno, Nevada. Known as the "Gigabit Factory", the Big Mac aims to double the supply of lithium-ion batteries in the world by 2020. The move caused great repercussions on Wall Street. Morgan Stanley Investment Company is very optimistic about the plan. "Seeing the Big Mac factory that Tesla has built, we believe that no one can find the right words and praise Tesla in Great contribution to the substantial price reduction of energy storage technology."
on the wayIn the late 1990s and the first 10 years of this century, it seems that there is no prospect or hope for electric vehicles: General Motors has given up their first electric car plan; the promising Toyota Prius is also a hybrid. By the end of 2014, the situation had turned sharply: Tesla's successful rise; Nissan's Leaf pure electric vehicle sales broke 30,000.
Although the denier has always existed, the development of energy storage technology is slowly getting back on track. Optimists believe that batteries, electric vehicles and renewable energy are bound to achieve commercial success, but this is still a theoretical prediction, reflecting the linear thinking of stock analysts.
In fact, the advancement of an independent technology is not the same as the overall progress in the field. Scientists in China and the United States are eager to invest in projects supported by the government, hoping that they can make subversive and groundbreaking recommendations. Considering the huge benefits of geopolitics, environment and economy, the government should continue to expand investment and support research on energy storage technology. We need to create a good environment for young researchers to understand that entering this field means long-term support. In addition, we also hope that researchers and scientists will follow the path of success and bring the world into a new era of energy.
