Strategic positioning of renewable energy

Recently, Wang Jun, Director of new energy and renewable energy department of The National Energy Bureau accept the media journalist to interview on the basis of the current development of the new energy and renewable energy in our country. He talked about China's energy strategy positioning planning target, its strategic steps are: 

 

Around 2010, renewable energy as a kind of complement energy account for about 10% of the total energy consumption.

Around 2020, renewable energy as a kind of replacement energy account for about 15% of the total energy consumption. 

Around 2030, renewable energy as the mainstream energy account for about 25% of the total energy consumption. 

Around 2050, renewable energy as the dominant energy account for about 40% of the total energy consumption. 

 

For the biomass energy with common concern, Director Wang talked about the current situation of the development of biomass energy. At present, the biomass energy technology mainly includes biomass energy power generation, biomass energy gasification, biomass energy liquid fuel and biomass pellet fuel in out country. By 2007, there are about 280 million household biogas pools in rural area, 2200 livestock and poultry farms and industrial wastewater biogas project, and the annual output of gas reached about 10 billion cubic meters. The installed capacity of biomass energy is about 30 million KW. There are about 100 biomass pellet fuel project with straw as raw materials and the power generation project are being built and the there are about 20 has been built in operation. The primary problems which faced with our country in the light of biomass energy development and applying are: separated resources and high cost of collecting raw materials. The biomass energy technology is still in the early stages except the biogas technology are mature, and it has big potential for exploration. For example, the recycling of straw, many people think that the straw is wastes. After that, people begin to realize the importance of recycling of straw. As popularize of recycling of straw, it has been developed and applied increasingly. The users of straw pellet mill are mainly in South regions, which are mainly pellet fuel, pellet fuel, and the fertilizer is the assisted digestion method.

 

Straw pellet machine developed from the feed pellet machine, so the processed pellets are mainly used as the feed for cow and sheep at the early stages of evolution. Later, the emergence of the slogan of energy saving and environmental protection, the rising price of coal and the changing environment of the city, straw briquetting and straw pellet increasingly permeate to biomass energy industry, it can supply the fuel for power generation at the same time. The construction of new socialist countryside promote the formation fuel in the area with good conditions (in the area with medium level income), to completely changed the dirty and bad situation of rural areas. It is suitable for the specialized household to process and sale locally, and the farmer accepts the client’s materials to process which charge for the processed pellet fuel. The biggest advantages of this method are easy for the farmers to reduce the sale price of formation fuel. And now, various levels of governments carry out the project of the building demonstrations which bring new challenge for the producers of biomass pellet fuel. That means that the biomass pellet fuel producers should adopt the method of small profit but quick turnover to lower the market prices on the basis of ensuring the product quality. As well as the commitment of there respects and good after sale service which reassure the farmers to promote the marketing process. The farmers use the formation fuel as a clean fuel.  

Using straw pellet machine to process straw materials is a common method in agriculture and animal husbandry industry. Straw pellets produced by straw pellet machine can be used as the energy to replace coal and oil for combustion, which solves the problem of on site burning of straw and makes great contribution to reduce haze. Straw pellet machine can effectively and rapidly process large amounts of straws and the pellets produced have the following advantages: first, the moisture content of straw pellets produced by the pellet machine is uniform, and the weight and size of which are exactly the same. Therefore, it is quite convenient for transportation and storage. Second, straw pellet machine can ensure the pure natural production without any adhesive so that the straw pellets produced are in excellent quality without any coking produced in the combustion process. Third, straw pellet machine is equipped with integrated pressure roller oil filling device to make each pressure roller get sufficient lubrication. The structure of spindle and shaft is special designed, there is no need to worry about the deformation and fracture of the spindle and shaft.

 

The existing biomass stoves can be used to burn the scattered straw, but there are flying ashes during consumption. Therefore, the formation fuel dose not brings this problem which realizes the clean burning to improve the indoor air quality and improve the village clearness at the same time. This could become an easy choice for the formation fuel to replace of coal. The applying of straw pellet mill is bound to promote the development of biomass pellet fuel, importing the advanced technology of foreign biomass pellet fuel, innovating on the basis of digestive absorption the advanced technology and our countries situation. We focus on the reliability of operation of equipment, life service of easy-wearing parts, repair convenience, reducing energy intensity to innovate, to reduce the production cost and prolong the service life, which make biomass pellet fuel and formation fuel play its role during the applying of biomass energy in our country. 
 

In general, there are four principles to follow during the development of biomass energy: development and utilization of biomass energy should be combined with promoting the economic development in rural areas; the development and utilization of biomass energy should be combined with improve the farmer’s living condition; development and utilization of biomass energy should be combined with protecting the ecological environment; the development and utilization of biomass energy should coordinated with food safety.

 

By 2050, the strategic positioning of renewable energy is the leading energy. Currently, three big energy supplying system has come into being in the world: electricity system, petroleum supplying system and natural gas supplying network. The three energy systems can not be changed during short period of time, but various economies have draw up the strategic planning of renewable energy. Until 2020 to 2050, the renewable energy account for about 20% and 50% of the world total energy consumption separately in Europe Union; in the Untied States, the wind power generation account for about 20% of the total machine capacity until 2030; biomass liquid fuel will replace 30% of fossil fuel; In Japan, the renewable energy will replace of 50% of the total energy supply by 2050. The strategic positioning of renewable energy in our country are: around 2010, the renewable energy account for about 15% of the total energy consumption, the strategic position is complement energy; around 2020, the renewable energy account for about 15% of the total energy consumption, the strategic position is alternative energy; around 2030, the renewable energy account for about 25% of the total energy consumption, the strategic position is mainstream of energy; around 2020, the renewable energy account for about 40% of the total energy consumption, the strategic position is the dominant energy.

 

As the confirmation of national energy strategic positioning, the development of biomass energy usher a new round of challenge of development in our country. As a big agricultural country, the production of crop straw is increasing year by year, and the treatment of crop straw become the most thorny problems for the new rural construction. Abandoning, misplacing and burning of straw not only waste the resource and pollute the air, but also give rise to a series of social problems. The government policy is the strong support for carry out the deep processing project to promote the development of straw feed, straw fuel, straw construction material etc into the green feed, green fuel and green construction material. The supporting of government policy resolve the trouble which bring by the simple processing of straw, it can found the new project to increase the income at the same time. At present, each province, city and autonomous region has bring the deep processing of crushing machine, straw pellet mill and straw briquetting charcoal into the government subsidy. This is a good business opportunity for the people who aspired to the development of biomass energy.
