正两部门发文严控煤电总量规模力促煤电有序发展国家发展改革委、国家能源局日前发布《关于促进我国煤电有序发展的通知》(以下简称《通知》发改能源[2016]565号),引导地方及发电企业有序推进煤电项目规划建设,促进煤电行业健康发展。《通知》指出,为指导各地和发电企业有序规划建设煤电项目,综合考虑未来3年煤电项目经济性、电力装机冗余程度等因素,国家将建立煤电风险预警指标体系,定期对外发布分省煤电规划建设风险预警提示;合理安排现有煤     

科学分析和处理煤与电的关系

煤与电既具有正相关性,也具有负相关性,煤电价格并轨对于煤炭和电力双方都是"双刃剑",并没有从根本上解决"煤电博弈"问题,推进电价市场化改革才是理顺煤炭与煤电企业关系的治本之策。电价市场化改革,短期需要完善煤电联动机制,长期应该形成真正由供需关系决定电价的机制。为此,煤炭和煤电企业应该认清波动规律,建立双赢理念,谋签长远合同,并通过互相参股,建立深层战略合作。     

我国煤电发展的宏观政策和资源环境约束

中国煤电发展面临着很强的政策约束和资源环境约束。随着生态文明建设和能源革命的推进,国家从2016年开始颁布系列政策化解煤电过剩产能,严控煤电总装机规模,新增煤电投资规模和装机容量大幅下降。另一方面,即使煤电清洁高效发展取得显著成果,煤电发展仍受到大气污染防治、水资源短缺、碳减排等资源环境条件的强约束。同时,面对生态文明建设目标要求和资源约束条件的趋紧,多个地区相继颁布"煤电禁令"。本文通过全面梳理影响煤电发展的宏观政策和资源环境约束条件,为有关部门和企业制定政策规划提供参考。     

2017年我国电力发展形势及2018年展望

2017年全社会电力消费增速回升,电力供应总体宽松,煤电企业经营困难。煤电去产能获得阶段性效果,电力体制改革取得重要进展。2018年,电力供需形势持续宽松,部分地区供需矛盾加大,燃煤发电企业继续面临经营风险。     

煤电节能减排再加码 五年内煤耗再降11g/kW·h

<正>近日,为落实国务院大气污染防治行动计划,国家能源局正在加紧制定《煤电节能减排升级改造行动计划》,以降低度电煤耗和煤电污染物排放,提升电煤比重和能效水平。目前,行动计划初稿已成形,并向发电企业征求意见。按照中央财经领导小组第六次会议要求,我国将提高煤电机组准入标准,对达不到节能减排标准的现役机组限期实施改造升级。国家能源局将综合利用行政手段和市场手段,推进煤电企业落实升级改造计划。这包括修改拟定技术标准,分地区、分企业签订节能减排目标任务书,出台有关土地、财税、电价、信贷等政策。

我国煤电转型的形势与建议

碳达峰、碳中和目标的提出为能源低碳转型提出了更紧迫、更高的要求，但是短期内我国以煤为主体的能源结构很难改变。在电力行业，稳步推动煤电转型，摆脱中国煤电为主的现状，是实现电力转型的重点，煤电在电力系统中从主力型电源向调节型和支撑型电源转型。本文分析了国外煤电转型的举措与挑战以及我国煤电发展现状，提出发挥制度优势，坚持能源自给自足，鼓励企业开发创新，煤电向新能源优化组合转型，对于指导我国煤电转型具有指导意义。     

能源局下发《关于进一步调控煤电规划建设的通知》

How to make the production of methanol/DME &#8220;GREENER&#8221;&#8212;Integration of wind power with modern coal chemical industry&#8212;

The urgency and necessity of alternative fuels give an impetus to the development of modern coal chemical industry. Coal-based methanol/DME is the key element of this industry. Wind power, whose installed capacity increased at a rate of more than 100% in recent years, has the most developed technologies in renewable energy. However, there still exist many unsolved problems in wind power for on-grid utilization. A new integrated system which combines coal-based methanol/DME production with wind power is proposed in this paper. In this system, wind power is used to electrolyze water to produce H₂ and O₂. The O₂ is fed to the gasifier as gasification agent. The H₂ is mixed with the CO-rich gas to adjust the H₂/CO to an appropriate ratio for methanol synthesis. In comparison with conventional coal-based methanol/DME system, the proposed system omits the expensive and energy-consuming ASU and greatly reduces the water gas shift process, which brings both advantages in the utilization of all raw materials and significant mitigation of CO₂ emission. This system will be attractive in the regions of China which have abundant wind and coal resources.     

U.S. DOE fossil energy fuel cells program

The U.S. Department of Energy's (DOE) Office of Fossil Energy's (FE) National Energy Technology Laboratory (NETL), in partnership with private industry, educational institutions and national laboratories, is leading the development and demonstration of high efficiency, high temperature solid oxide fuel cells (SOFCs) and fuel cell turbine (FCT) hybrid power generation systems for stationary markets including auxiliary power units (APUs), distributed generation (DG) and large, coal-based central power plants. The DOE FE fuel cells program has three aspects: the Solid State Energy Conversion Alliance (SECA), Fuel Cell Coal Based Systems for central power, and the High Temperature Electrochemistry Center (HiTEC). The SECA goal is to decrease SOFC system cost to US$ 400 per kilowatt (kW) by 2010 for stationary markets. DOE FE is ultimately concerned with coal-based central power plants such as FutureGen. The goal is to aggregate SECA-type fuel cells into larger systems and to produce a very high efficiency megawatt-class FCT hybrid for testing at FutureGen. The low-cost, US$ 400 kW⁻¹ SECA FCT hybrid is a key component to achieving 60% efficiency by 2020. Advanced aspects of solid oxide technology are part of HiTEC R&D. Technical progress and advances are discussed for all three program aspects.

水资源对“三西”地区发展煤基液体燃料的制约研究

"三西"地区(山西、陕西北部、内蒙西部)是我国煤炭资源最为丰富的地区,近几年来,为促进地方经济发展、延长煤炭产业链,该地区对发展煤基液体燃料兴趣浓厚,然而我国以煤制油为代表的煤基液体燃料产业目前存在较大的不确定性,水资源是影响富煤地区发展煤基液体燃料的根本因素。本文分析预测了未来"三西"地区的水资源可供量大小,进而探讨了该地区的煤基液体燃料的发展空间。研究数据表明,长远看由于水资源的约束,该地区尽管煤炭资源丰富,也不宜发展高耗水的煤基液体燃料产业。

Impacts of wind power generation and CO2 emission constraints on the future choice of fuels and technologies in the power sector of Vietnam

This paper examines the impacts of wind power generation on the future choice of fuels and technologies in the power sector of Vietnam. The study covers a time frame of 20 yr from 2005 to 2025 and the MARKAL model has been chosen to be adaptable to this specific task. The results of the study show that on a simple cost base, power generated from wind is not yet competitive with that of fossil fuel-based power plants. In order to make wind energy competitive, either carbon tax or an emission reduction target on the system must be imposed. The presence of wind power would affect not only the change in generation mix from coal-based power plants to wind turbines but also an increase in the capacity of other technologies which emit less carbon dioxide. It thus helps reduce fossil fuel requirement and consequently enhances energy security for the country. The study also shows that wind turbine in Vietnam could be a potential CDM project for annex I party countries.
