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(fēng)能、生物質(zhì)能、波浪能、潮汐能、海洋溫差能、地?zé)崮艿?。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(dòng)再生它是相對(duì)于取之不盡、用之不竭的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(fù)荷中心的逆向分布資源與負(fù)荷的匹配性相對(duì)較差在某些地區(qū)難以消納;中國經(jīng)濟(jì)進(jìn)入新常態(tài)電力需求放緩裝機(jī)容量出現(xiàn)相對(duì)過剩;“三北”地區(qū)供電結(jié)構(gòu)中調(diào)峰電源相對(duì)較少尤其是自備電廠供熱機(jī)組比例較大冬季采暖期調(diào)峰能力進(jìn)一步受限;輔助服務(wù)政策不到位或執(zhí)行不力;可再生能源開發(fā)建設(shè)快配套電網(wǎng)規(guī)劃建設(shè)相對(duì)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(shù)水平低成本高
2. Low technical level and high cost
技術(shù)水平有待提高成本應(yīng)通過進(jìn)一步的技術(shù)進(jìn)步和產(chǎn)業(yè)升級(jí)來降低比如水電建設(shè)中的環(huán)保和移民問題增加了開發(fā)難度導(dǎo)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(fēng)電風(fēng)力發(fā)電設(shè)備制造、微選址、海上風(fēng)電設(shè)計(jì)和建設(shè)等核心技術(shù)推動(dòng);太陽能晶體硅、薄膜產(chǎn)業(yè)、無害化處理、火力發(fā)電一體化技術(shù)進(jìn)一步提高轉(zhuǎn)化率實(shí)現(xiàn)實(shí)惠上網(wǎng);生物質(zhì)天然氣一體化、航空燃料和綠色生物煉制等關(guān)鍵技術(shù)和產(chǎn)業(yè)水平有待提高;海洋能和地?zé)崮艿陌l(fā)展尚未達(dá)到成熟應(yīng)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(bǔ)貼差距擴(kuò)大
3. The subsidy gap of funds has widened
在可再生能源發(fā)展的初始階段需要鼓勵(lì)、支持和扶持政策??稍偕茉窗l(fā)展基金來源單一很難征收額外的電價(jià)資金的補(bǔ)貼被推遲風(fēng)電和光伏的一些發(fā)電企業(yè)存在資金周轉(zhuǎn)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.
