The world is re-electrified. Forecast data from the International Renewable Energy Agency (IRENA) show that by 2050, global electricity generation will reach 47.9 trillion kwh, an average annual growth rate of 2%, renewable energy generation will then meet 80% of global electricity demand, the “re-electrification” is the magic key to this revolutionary upheaval. Further electrification is not just an alternative to fossil fuels in the consumer sectors, but also in the depth of application of these energy production processes of transformation of the whole industry chain. CASS ‘2019 World Energy Blue Book “that raise the level of electrification again rely mainly on three ways: smart grid, renewable energy sources (power generation) as well as the popularity of electric vehicles. The digital transformation is go hand in hand, a strong increase electrification of power again. Then, as the locomotive of the European economy and the future development of the German benchmark is how to achieve and then electrified it? Germany re-electrification of the road began to retreat from coal early 2019, German President Steinmeier (Steinmeier) took the last piece of coal from the hands of the miners, and finally a hard coal mine in Germany – Ruhr coal mine located in Hani Er, official Close, which marks the hard coal mining in Germany officially became history. This is the realization of a microcosm of the German energy transformation ambitions and goals. Prior to this, in May 2016, the German solar and wind energy to reach the peak, renewable energy provides 87.6% of the energy demand, setting a historic record. This also allows the transformation of energy policy based on energy for sustainable development (Energiewende) to see the dawn of victory Germany. And all this must go back to the beginning of this century, based on the German government to address climate change, to avoid the nuclear risk, improve energy security and ensuring economic competitiveness and growth began to vigorously promote energy transformation. In 2000, Germany enacted the “Renewable Energy Law (EEG)”, defined the important role of renewable energy in the energy mix, and its investment in the energy market principle protection and energy production process priority. In the framework of energy transition, 2035 in Germany 55-60% of the power from renewable energy generation by 2050 the proportion of renewable energy will reach 80%. At the beginning of the energy transition Control Engineering Copyright , many European countries did not agree. Such as nuclear energy dominated the French believe that the security of nuclear power can be guaranteed, the German approach is too cautious. However, in recent years, fromChanges in Germany in the field of energy supply point of view, although these goals are twists and turns, but gradually approaching towards a bright future.
Although in the literature, and no longer electrified German native (Reelektrifizierung) concept. However, all areas of its energy policy transformation involved almost all point to three key ways and re-electrification of the core areas, committed to the development of large-scale hydro, wind, solar and other clean energy from energy production and re-electrification use and complete end-consumer electricity depth alternative to coal, oil and other fossil fuels, thus completing climate protection in Germany and Europe’s long-term goals. Reconnect the smart grid industry in the wave of “re-electrification” (that is, the transition from the fuel supply to the power supply), the power gradually as new energy use in energy-intensive heating, transportation and industrial production, electricity supply in the process We need more and more new technologies and rules. In the energy transition in Germany, the industry in which the coupling is a critical step. Coupled industry refers to the energy consumption sector – buildings (heating and cooling), transport and industry sectors – energy supply connected to each other (integration) and electricity. It is not only able to supply power through the traditional energy industry to achieve “decarbonization” the goal, through a combination of energy storage technologies and can solve the problem of supply and demand in the course of a series of energy transition in the new energy into the grid caused by the mismatch . Therefore, CONTROL ENGINEERING China Copyright , and the rise of the concept of coupling energy storage industry broke out, it will be a crucial step in the development of its energy sector. One of the main energy transition in Germany focused on the field of electricity production, renewable electricity expected to gradually replace traditional energy sources and for security reasons abandoned nuclear energy supply. Ended in 2018, renewable energy accounted for 36% share of total electric power. While in other areas, particularly in construction and transport, its energy consumption is still mainly dependent on fossil fuels, renewable energy accounts for only 13%. And if the industry can bring electrification in these areas, it will result in a revolutionary impact on these industries.
so that the transportation industry decarburized key technologies include the use of compressed natural gas (the CNG), bio-fuel, cell, hydrogen gas or a synthetic fuel. The heat pump is considered to be the key technology to integrate heating industry power energy systems. Using the heat pump apparatus from the outside air, ground water or geothermal power to useForce to circulate the hot / cold liquid. The heat pump installation be synchronized with the thermal insulation of buildings, in order to reduce energy losses and to ensure that the entire system becomes extremely high. Coupling effect will further enhance the stability and flexibility of the entire energy system of inter-industry to address the problem of differentiation due to different energy supply generated media currently exist. In Germany, it outlined a feasible blueprint, and the first step towards future energy system exploration. At the same time , and the policy level also strongly contributed to the economy as a whole among the participants will be able to supply electricity as the default way to improve energy efficiency, the optimal allocation of benefits according to the country and storage resources within the scope of the premise of re-electrification, energy efficiency will rise again one level. The new storage speed and then leap electrification conventional power generation systems because it can be adjusted according to user needs, without too much storage capacity. But with the grid of renewable energy use accounted for the gradual increase in Germany, the situation has changed can not be ignored. For example: Because the power of the wind turbine and the solar photovoltaic power generation system for the strong dependence of the weather, with diversification distributed generation systems, coordinated control of various power network are increasingly dynamic. Therefore, CONTROL ENGINEERING China Copyright , to develop clean energy, high-capacity storage is essential. In addition to the protection of large consumptive capable of renewable energy power, energy storage technology also play a role in the perfect side coupling of the feed industry. Therefore, CONTROL ENGINEERING China Copyright , new energy consumptive point of view, in the next stage of energy transformation, energy storage technologies will undoubtedly be the key to a breakthrough in the industry coupled. As the investment and operating costs, in the foreseeable future decades, large-scale energy storage facilities can only explore forward in a number of demonstration projects. Therefore, CONTROL ENGINEERING China Copyright , a myriad of small household energy storage devices and electric car batteries as the energy storage device, which became the likely future demand for high-capacity storage, and is expected to push Germany open. Alternatively a different perspective, the share of renewable energy rising trend of the overall energy system that is also a highly concentrated energy from the system to the dispersion,Flexible and distributed renewable energy systems change, energy storage devices and home electric vehicles distributed energy storage may just provide the flexibility required for this conversion. According to McKinsey predicted: “By 2035, based on a simplified design progress, economies of scale and process, the total cost of the energy storage system will drop 50-70 percent.” International Renewable Energy Agency (IRENA) predicts that by 2030, installing the battery price will drop 50% to 66%. Center for European Economic Research (ZEW) German energy industry experts expected, in view of market forces, as well as transport and energy transformation in the expanding field of heating, the demand for electricity storage will increase substantially next few years. Currently, about half of new residential solar photovoltaic systems are equipped with a battery energy storage system. According RWTH research shows that more and more families, said the price higher and higher, in order to reduce electricity consumption and reduce dependence on the power grid, and more willing to use photovoltaic energy storage system.
A German family installed the first German 100 000 Source household photovoltaic energy storage system: the German Solar Energy Society (BSWSolar)
Solar Energy Industries Association (BSWSolar) expects household batteries will continue to rapidly growing popularity, the price will fall further economic situation change with the direction of the energy storage system is more conducive to the popularity of the household, Germany may exceed the threshold of 200,000 systems in 2020. In addition, after the construction in early 2000, hundreds of thousands of rooftop PV system in operation for almost 20 years, it will reach support costs (so-called feed-in tariff) critical point, these systems will continue to be close to zero cost of power generation, this household batteries such popularity may be further accelerated. At the same time , the German utilities, especially electricity companies are also gradually learn to adapt to the future development of a flexible energy system, strengthen risk management and response capabilities. Currently developed more mature an innovative business model is contract energy management business model, namely: energy service providers can provide device management and transaction management for the owners, in the case of the owners of the guarantee benefits, the amount of charge a service fee or press The royalty. Some large German utilities (such as EnBW), the user will be cheaper to sell or lease their own household photovoltaic systems and energy storage devices, in order to obtain permission to manage those devices, thus creating a perfect very own energy community occupy localEnergy services market. Adds digital technology specification standards in the field of intelligent home wings, big data algorithms and smart grid, but also to promote the application of cutting-edge technology. With the digital wave, energy and resources assigned to intelligence, unprecedented efficiency improvement, energy costs have dropped significantly. In Germany, the “energy transformation” can also be seen as the largest ever at the national level of information technology upgrade project: Department of Energy’s Federal Ministry of Economics (BMWi) the digital transformation of the energy industry is an integral part of the “energy transition”. Germany transportation industry believe that the most revolutionary changes in digital technology will occur in road traffic and transportation. Ubiquitous Internet and automation technology may change the mode of transport of people and goods fundamentally. Automation, Internet, electricity and shared (ACES) technology will have a profound impact on the future energy consumption and carbon emissions from the transport sector. Building Intelligence technology the construction sector, such as smart thermostats and lighting, is expected to be in 2017-2040 years, the digital technology award significantly reduce energy consumption in residential and commercial buildings. By 2040, the cumulative energy saving is expected to reach 65 trillion kwh, equivalent to non-OECD (OECD) countries, the total final energy consumption by 2015. In the power industry, digital technology can reduce electricity costs by four systems: saving operation and maintenance costs; enhance the efficiency of power generation and grid; reduce unplanned downtime; and extend the life of the facility. Using digital technology, will enable 2016–2040 years of annual energy costs by $ 80 billion, equivalent to 5% of the global total costs of electricity generation. Oil and gas industry has been a history of traditional use of digital technology, especially in the upper reaches of the production chain, the huge potential of digital technology. For example, the introduction of micro-sensors in the production system and the optical fiber sensor can increase the overall yield or recovery of oil and gas; and the use of automatic rig underwater robot inspection and repair infrastructure, monitoring tanks and pipes. In the future, more wearable devices, intelligent robots and artificial intelligence technology will be used in the oil and gas industry. The spread of digital technology, the oil and gas industry can reduce the production cost by 10% -20%, recoverable oil and gas resources increased by about 5%. Re-electrification of the main event: the German automobile industry to catch up with pure electric car manufacturing giant Currently, about one-fifth of Germany’s greenhouse gas emissions come from transportation. Although significantly improve the energy efficiency of the vehicle, but the energy saving effect is transport capacity, engine powerThe rate of increase in vehicle weight and offset. This medium-term target set by the German government in 2050 to protect the climate plan is that the greenhouse gas emissions from the transport sector in 2030 should be reduced by 40% -42%. From the technical characteristics and development trends, development of pure battery electric vehicles is the core of future traffic transition. Around electric vehicles, the German government will tax, infrastructure construction, purchase subsidies, manufacturing and recycling, innovative aspects of travel patterns to give policy support, taking into account the low-carbon transition aviation, maritime transport, and to strengthen the European Union to focus on international cooperation, to jointly promote the transformation of the German transportation. German car is really anxious. German Automobile Industry Association (VDA) convened in April 2019 senior major car manufacturers and parts suppliers held technology conference, the German automotive industry representatives gathered to discuss the country’s development path of vehicle electrification technologies. Car manufacturers agreed future transportation system will be fully electrified. According to the German “Handelsblatt” reported that, after the VDA Technology Conference, Volkswagen, BMW and Daimler three German car giant enterprises of the head and held a conference call to discuss and eventually reached a consensus that in the short term, the German automotive industry the future belongs to the electric car. It is reported that Volkswagen, BMW and Daimler’s head of Diss, Ke Luge and Zetsche agreed that the next 10 years, electric vehicles will become the most important technology German carmaker comply with EU environmental regulations. · VDA president Bernhard Mattes also said that the next three years, the German automotive industry will invest nearly 60 billion euros in electric vehicles and automatic pilot areas to ensure future competitiveness of the German automotive industry. Auto giants also speak out, to take appropriate administrative measures across the EU, to promote the development of electric vehicle industry. They believe the government level, in order to achieve the EU carbon reduction targets, Germany will be the future of new energy vehicles as the main direction of development is a choice. At the same time , Merkel’s government announced early November 2019, will invest 3.5 billion euros expansion of public electric vehicle charging pile, built in 2030 for 1 million charge pile. Germany is currently charging pile only 21,000 total. The basic logic is, 2030, Germany is expected to have seven million to 10 million electric vehicles. 2020 March 6, 2020 McKinsey in its release of “Electric Vehicle Index”This report is to make a bold hypothesis: the electric car manufacturing in Germany will exceed China. McKinsey predicts that by 2024, the German carmaker’s market share in terms of the global electric automobile production capacity from 18% last year rose 29%, with over 1.7 million electric automobile production capacity, Germany can become the first global market in 2021 leader, and ahead of China. The German government will also purchase consumer electric vehicles and hybrid vehicles to provide subsidies of up to 6000 euros, and promised to vigorously expand the charging infrastructure in the country. Of course, the McKinsey study does not include potential production Tesla plans to open a factory near Berlin Gigabit, nor does it consider the potential impact of the new virus outbreaks crown on the market. If you include Tesla super factory in Berlin and Ningde era in Figure eastern Thuringia battery factory built to provide low-cost power for the car manufacturers in Germany, the Germans will be more to accelerate progress in the era of electric vehicles. SPIEGEL ONLINE analysts believe that, in Tesla representative of the “new forces” and the traditional auto industry, who will be an advantage CONTROL ENGINEERING China Copyright on the development of electric vehicle industry, it is hard to say. Like this century-old Volkswagen, its advantage lies in mass production and quality, and to subvert the automotive industry known as Tesla, whose expertise lies in driving style, computer technology and the Internet. Volkswagen CEO Herbert Edith (Herbert Diess) also said that Volkswagen’s advantage lies in hardware, Tesla has the advantage of software CONTROL ENGINEERING China Copyright , both of which have a broad space for cooperation. Musk talks with Volkswagen, the possibility of cooperation, shares of discussion. Epilogue: Germany and China again electrified the new infrastructural who are the future of the road? Not difficult to see, and then electrified in the vanguard of climate and environmental protection in Germany, is at full speed with the energy transformation explore the new way for the future of mankind, through a re-electrification of the road to sustainable development, a path to climate protection is the ultimate goal of the new economic and social development of the road. Coincidentally, China at the time of the outbreak has not been fully extinguished, has just announced a new strategy for infrastructure, include: 5G infrastructure, UHV, intercity high-speed railway and urban rail transportation, new energy vehicles charging pile, large data centers, artificial intelligent, Internet industry. If only from the above nameHe says can not tell the difference between it and the German re-electrification, then at the application level, you can more clearly see the road re-electrification of Germany and China strategy or new infrastructure would be similar. In simple terms, 5G infrastructure corresponds to the car networking, networking, the Internet industry, the enterprise cloud, artificial intelligence and telemedicine; UHV power industry and the corresponding re-electrification of the smart grid; inter-city high-speed railway, rail transport and new energy vehicle charging pile, corresponds to the re-electrification of the transport sector; large data corresponding to the center is the digital support financial, security, industry business management and personal life; artificial intelligence and intelligent home service robot, certain equipment and automatic driving in areas such as correspondence; industrial production directly to the Internet is in the business intelligence, collaboration between the enterprise value chain, and personalized and interactive business with the terminal. Each of the above fields and each of which can be supported by more or less another technique involves electrification or redefinition. Compared with Germany and the European Union Official Imperial partner-cum-rival China, Germany and China re-electrification new infrastructure look towards the same road.
