沼氣提純沼氣是可再生能源嗎?了解后可再生能源的發(fā)展面臨哪些問題?
Is biogas purification a renewable energy source? What are the problems faced by the development of post renewable energy?
可再生能源可以在自然界中回收它們包括太陽能、水電、風能、生物質能、波浪能、潮汐能、海洋溫差能、地熱能等。它是一種取之不盡、用之不竭的能源不需要人類的參與就可以自動再生它是相對于取之不盡、用之不竭的不可再生能源而言的一種能源。
Renewable energy can be recycled in nature, including solar energy, hydropower, wind energy, biomass energy, wave energy, tidal energy, ocean temperature difference energy, geothermal energy and so on. It is an inexhaustible and inexhaustible energy, which can be regenerated automatically without human participation. It is an energy relative to the inexhaustible and inexhaustible non renewable energy.
1、利用效率低
1. Low utilization efficiency
可再生能源系統(tǒng)消納容量有待提高利用效率有待提高主要是由于以下原因:基于我國資源稟賦和負荷中心的逆向分布資源與負荷的匹配性相對較差在某些地區(qū)難以消納;中國經濟進入新常態(tài)電力需求放緩裝機容量出現(xiàn)相對過剩;“三北”地區(qū)供電結構中調峰電源相對較少尤其是自備電廠供熱機組比例較大冬季采暖期調峰能力進一步受限;輔助服務政策不到位或執(zhí)行不力;可再生能源開發(fā)建設快配套電網規(guī)劃建設相對滯后電力通道輸送能力有待提高。
The consumption capacity of renewable energy system needs to be improved, and the utilization efficiency needs to be improved, mainly due to the following reasons: Based on the reverse distribution of China's resource endowment and load center, the matching between resources and load is relatively poor, which is difficult to be consumed in some areas; China's economy has entered the new normal, the power demand has slowed down, and the installed capacity is relatively surplus; In the "Three North" area, the peak load power supply in the power supply structure is relatively small. Auxiliary service policies are not in place or poorly implemented; The development and construction of renewable energy is fast, and the planning and construction of supporting power grids lags behind. The transmission capacity of power channels needs to be improved.
2、技術水平低成本高
2. Low technical level and high cost
技術水平有待提高成本應通過進一步的技術進步和產業(yè)升級來降低比如水電建設中的環(huán)保和移民問題增加了開發(fā)難度導致成本較高;
The technical level needs to be improved, and the cost should be reduced through further technological progress and industrial upgrading. For example, the problems of environmental protection and immigration in hydropower construction increase the difficulty of development, resulting in higher cost;
如何有效利用海上風電風力發(fā)電設備制造、微選址、海上風電設計和建設等核心技術推動;太陽能高效晶體硅、薄膜產業(yè)、無害化處理、火力發(fā)電一體化技術進一步提高轉化率實現(xiàn)實惠上網;生物質天然氣一體化、航空燃料和綠色生物煉制等關鍵技術和產業(yè)水平有待提高;海洋能和地熱能的發(fā)展尚未達到成熟應用階段。
How to effectively use the core technologies such as offshore wind power, wind power equipment manufacturing, micro site selection, offshore wind power design and construction; Solar energy efficient crystalline silicon, thin film industry, harmless treatment and thermal power generation integration technology to further improve the conversion rate and realize affordable access to the Internet; Key technologies and industrial levels such as biomass natural gas integration, aviation fuel and green bio refining need to be improved; The development of ocean energy and geothermal energy has not yet reached the mature application stage.
3、資金的補貼差距擴大
3. The subsidy gap of funds has widened
在可再生能源發(fā)展的初始階段國家需要鼓勵、支持和扶持政策。國家可再生能源發(fā)展基金來源單一很難征收額外的電價資金的補貼被推遲風電和光伏的一些發(fā)電企業(yè)存在資金周轉困難和虧損等問題。
In the initial stage of renewable energy development, countries need to encourage, support and support policies. The source of the national renewable energy development fund is single, it is difficult to levy additional electricity price, the subsidy of funds is delayed, and some power generation enterprises of wind power and photovoltaic have problems such as capital turnover difficulties and losses.
