The hottest energy storage industry opportunities

Tibet: the opportunity of energy storage industry is worth looking forward to

Tibet, which is closest to the sun, is one of the regions with the strongest solar radiation in the world, and has unique advantages in solar energy resources. In the current situation of energy shortage, climate warming, serious environmental pollution and the innovation of the world energy structure, the development and utilization of green and clean energy has become the focus of the world

Tibet is endowed with unique resources

located in the West and south of the Qinghai Tibet Plateau, accounting for more than half of the area of the Qinghai Tibet Plateau. Areas with an altitude of more than 4000 meters account for 85.1% of the total area of the region. Known as the "roof of the world" and the "third pole of the earth", Tibet is the highest altitude place in the world. The terrain of the whole region can be divided into three regions: Northern Tibet Plateau, Yarlung Zangbo River Basin and eastern Tibet canyon

Tibet has strong solar radiation and long sunshine duration, with an annual sunshine duration of 1443 3 hours, including more than 3000 hours in most of Ali Region and the west of Shigatse City, hours in the central and western parts of Naqu region, the east of Shigatse City and the west of Shannan City, and hours in the east of Naqu region, the west of Changdu City, Lhasa River Valley and Nianchu River Valley

Tibet is rich in light resources, wind resources, water resources and mineral resources, which made the delegation deeply understand

first, lighting resources. The annual total solar radiation value in Tibet reaches kcal/cm2, which is nearly twice that of the eastern coastal areas of China

second, wind resources. Tibet is one of the regions with the largest number of gales (≥ force 8 or 17 m/s) in the country. The annual average number of gale days is as many as days, up to 200 days, which is twice that of eastern China at the same latitude

third, water resources. According to statistics, the total amount of water resources in the region is 439.465 billion cubic meters (excluding groundwater), accounting for 16.21% of the total river runoff in the country, ranking first in the country; The water resources per capita and the water volume per mu also rank first in the country; The theoretical reserve of hydropower resources in the region is 210million kW, and the technical exploitable capacity is 140million kW, both ranking first in the country

fourth, mineral resources. At present, there are 103 kinds of minerals (subspecies) discovered in Tibet, 49 kinds of minerals with confirmed mineral resource reserves, and more than 3000 deposits, occurrences and mineralization points. Among them, 5 kinds of energy minerals have been found, and 3 kinds of resource reserves have been identified; 32 kinds of metal minerals have been found, including 19 kinds of verified resource reserves; 64 kinds of non-metallic minerals have been found, including 26 kinds of verified resource reserves; Two kinds of water vapor minerals are found, and one kind of resource reserves is identified. The dominant mineral resources discovered in the region mainly include copper, chromium, lead zinc silver polymetallic, molybdenum, iron, antimony, gold, salt lake lithium boron potassium ore, high-temperature geothermal, natural mineral water, etc., all of which have broad prospecting prospects. Among the minerals that have been identified as mineral resource reserves, chromium and copper have retained resource reserves, and the prospect of salt lake lithium resources and high-temperature geothermal reserves rank first in the country

based on the general idea of "taking port interconnection as the foundation and the development of open industries as the core", Tibet will strive to promote the construction of important channels open to South Asia. With Lhasa as the center and Shigatse as the frontier, we will realistically create a new pattern of opening-up and development that faces Nepal and other South Asian countries, integrates into the Bangladesh China India Myanmar economic corridor, and internally connects regional development zones such as the Shaanxi Gansu Ningxia Qinghai economic belt and the Sichuan Chongqing economic circle

Tibet has unique geographical advantages, adjacent to India, Nepal and other South Asian countries, with a border of more than 4000 kilometers. It is China's strategic hub and open door to South Asia, and is an important node of the "Southern Silk Road" in history. Tibet is a key area for the opening-up and development of border areas determined by the state and an important channel for opening up to South Asia. It is also an important gateway of the Bangladesh China India Myanmar economic corridor, and the Qingdao Haiba energy group, which was once enthusiastic about the Paoma enclosure. Tibet will play an important role in the construction of the national "the Belt and Road"

the general trend of new energy development

the roof of the world is one of the ecological barriers in Eurasia. The development and utilization of solar energy resources as green and clean energy in Tibet is of great value and far-reaching significance. The full application of solar energy can not only reduce Tibet's dependence on fossil energy, protect the ecological environment, effectively promote the economic development and social stability of Tibet, and benefit the people, Moreover, it can greatly protect the ecology and climate of Eurasia, play a unique role and make special contributions to the improvement of global ecology and climate

Tibet has many kinds of renewable energy and rich reserves, and it is one of the main enrichment areas of renewable energy in China, ericospini said

it is understood that the theoretical reserve of solar energy in Tibet is more than 600million kW, and the technological development capacity is more than 300million kW

Tibet ranks first in the country in terms of solar energy resources and is also one of the richest regions in the world. The average annual solar radiation in most areas of the region reaches megajoules/square meter, which is about twice that of plain areas at the same latitude. At the same time, the sunshine hours are also the high-value center of the country. The annual average sunshine hours are 3300-3600 hours, and the distribution is increasing from east to west. The proportion of direct radiation in the total radiation is 56%-78% throughout the year and 71%-78% in summer

Tibet is rich in renewable resources, but due to the weak power construction, the cumulative installed capacity of photovoltaic power plants in the Tibet Autonomous Region is nearly 800MW, but most photovoltaic power stations are in a state of power restriction for a long time. The lack of delivery channels during the wet season leads to the abandonment of water and light, while in the dry season, due to the reduction of adjustable hydropower, it will also lead to the abandonment of light for the consideration of electrical stability. At present, the abandonment rate of photovoltaic power stations in Tibet is as high as 20%, There is a real demand for energy storage

nevertheless, from the perspective of the strategic development of energy in Tibet, whether out of the needs of the environment or the strategic requirements of developing energy according to local conditions, hydropower, solar energy and wind energy will be the main renewable energy in Tibet in the future, and will also become the supporting performance source of power in Tibet

to enter the project construction in Tibet, new energy enterprises need to do a good job in seven aspects: the challenge of high altitude to human, material and machine, site survey, frozen soil construction, design and environmental protection, scheme design and equipment selection in high altitude areas, team cohesion and project cost control

in addition, affected by the plateau climate, Tibet has high requirements for the selection of electrical equipment. The use of ordinary electrical equipment in plateau areas will reduce the working efficiency of the equipment and reduce its service life. Therefore, when building photovoltaic and energy storage power stations in Tibet, plateau type equipment should be selected as much as possible, and many technical challenges still exist

it is understood that in the middle of 2018, Tibet Zhongdian will realize 500kV connection with Changdu power. The development of renewable energy in Tibet has a huge and predictable prospect, but it needs to be treated with caution during the 13th Five Year Plan period. With the improvement of power access and consumption and the start of the construction of export channels, the future of renewable energy in Tibet is worth looking forward to

for a long time, due to the lack of conventional energy, the vast agricultural and pastoral areas in Tibet have formed the traditional living habits of using cow and sheep dung as fuel, cutting firewood for heating, cutting grass and burning fire. According to the goal and task of building a moderately prosperous society in the region and the whole country by 2020, the autonomous region has clearly put forward the basic requirements for the construction of a moderately prosperous society with "six connections" (electricity, roads, water, mail, communications, radio and television) as the main content in view of the actual living conditions of farmers and herdsmen. However, the energy supply of the whole region, especially the power supply, can not meet the production and living needs of towns and villages, which has created a prerequisite obstacle to the construction of a moderately prosperous society in the whole region

Tibet's ecosystem is fragile, farmers and herdsmen live scattered, with an average of people per square kilometer, and the vast pastoral areas have large population mobility, a wide range of mobility, small actual domestic power consumption, high fixed electricity construction costs, and cannot meet the production and living requirements of the vast number of farmers and herdsmen. Environmental protection power supply, decentralized power supply, continuous power supply and low-power power power supply are the inevitable choice for the natural and social conditions and population distribution at the grass-roots level in the vast agricultural and pastoral areas of Tibet. In agricultural and pastoral areas, people's energy is mainly biomass energy such as livestock manure and firewood. This kind of energy not only has a low output rate, but also has an impact on the ecological environment of Tibet. Therefore, it is an inevitable choice for Tibetan people to change the backward energy utilization mode and develop a green, low-carbon and energy-saving new energy utilization mode represented by solar energy

in recent years, with the great attention and support of relevant national ministries and commissions and the autonomous region, Tibet has successively implemented a number of solar energy promotion demonstration projects with high social and economic benefits and ecological benefits, such as the "sunshine plan", "light of science plan", "Ali photoelectric plan", "power supply project in non electricity villages in western provinces and regions", "power construction project in non electricity areas", "golden sun project"

now, Tibet's solar energy resources have been widely used in all aspects of production and life, such as lighting, communications, radio and television, water pumping irrigation, heating, etc. the technology of using and controlling light energy is becoming increasingly sophisticated and diversified. Solar stoves and solar water heaters have reached thousands of households, which not only improve people's living quality, but also reduce the damage to the environment

due to the fragile ecological environment in Tibet, high cold and hypoxia, sparsely populated, scattered farmers and herdsmen, and difficult to cover electricity, the increasingly prosperous farmers and herdsmen are eager to end the history of lighting with butter lamps and candles as soon as possible, and hope to use electric lights, listen to stereo and watch TV. People's living demand for electricity is growing. Tibet implemented the strategy of replacing firewood, and the promotion and application of solar photovoltaic power generation made their dreams come true. The development of solar energy enables the application and promotion of solar greenhouse technology, so that there are some seasonal fresh vegetables and fruits in cities and towns all year round, which greatly enriches the people's vegetable baskets, instead of being completely transported by car or air from the mainland as before

the wind solar complementary power station realizes the all-weather power generation function, which is more economical and practical than using wind turbine and solar energy alone, and can effectively solve the power consumption in remote pastoral areas, border guard posts and power-free areas in Tibet

in addition, solar energy resources are also widely used in other fields. At present, in Tibet, the signal coverage is becoming wider and wider. China Mobile has built the largest solar base station group in the global communication field in Tibet. Among the more than 1000 base stations of China Mobile in Tibet, solar base stations account for 78.79% of the total. Even in the Everest region with the highest altitude and the worst climate in the world, Tibet Mobile has achieved the full network coverage of mobile signals along the Everest climbing route by building solar mobile base stations at an altitude of 5200 meters, 5820 meters and 6500 meters, as well as network projects along the way, bringing convenience and life support to climbers and tourists

"the realm of sunlight, driving the light forward" is a beautiful vision that is gradually being realized, which is the era and major mission of Tibetan new energy practitioners

the development and utilization of solar energy resources in Tibet has been increasingly moving towards industrialization. With the progress of science and technology, the "law of controlling light" has also become more and more deep into people's lives. People on the plateau are moving forward under the "sunshine" and towards new hope

storage must maintain resource conservation as the starting point to continue the application and write a new chapter.
