As the world oil and gas prices remain high, the global power generation are major changes in the energy mix, coal will again become the preferred fuel for new power plants.

According to local media, the world’s largest manufacturer of power generation equipment 3 - France’s Alstom, Germany’s Siemens and the U.S. General Electric, recently made a similar conclusion, respectively. Alstom and Siemens forecasts show that over the next 10 years, an average annual power generation equipment orders for 120 megawatts, the amount of 50 billion U.S. dollars, of which 40% of coal-fired units, while the proportion of gas-fired generating units will drop to 25% to 30%. Alstom Power Generation CEO Joubert that “electricity market structure will undergo a fundamental change in the fuel is from natural gas into coal.” GE also said orders for power generating equipment is expected to be a “more balanced picture,” natural gas Unlike in recent years, far less dominant.

statistics show that between 1997 and 2001, natural gas is the preferred fuel for power generation around the world, 60% to 70% of new power plants are used, while the use of coal power plants only about 20% to 30%. In 2005, the power generation fuel the trend of turning coal began to take shape, out of 120 megawatts of power generation equipment orders, only 20% to 30% of gas-fired units. According to analysis, the emergence of this turning point There are two major factors have contributed to: First, the market worried about rising gas prices and supply security issues, most recently between Russia and Ukraine gas price dispute exacerbated this concern. At present, many Asian countries still lack a stable natural gas supply channels, while the next 10 years, half of the orders for new power plants will come from these countries. In order to ensure energy security, they will increase the proportion of coal-fired generating units. Second, the current coal-fired power plants to reduce emissions of many new technologies are already quite mature, making coal-fired power adverse impact on the environment greatly reduced.

the United Kingdom as an example. The energy field of science, the British leader in the world, particularly in reducing carbon dioxide emissions, clean energy research and development advantage. As an island nation, Britain’s very sensitive to climate warming and sea level rise on the control of greenhouse gases and carbon emissions are also paid special attention has now developed the technology portfolio of carbon reduction, also known as “green coal technology” or clean coal technologies. The use of this technology can reduce carbon emissions 50-60%, so that the use of the environmental impact of coal power generation to gas-fired unit level. As the coal is relatively cheap, so clean coal technology has broad application prospects. In order to reduce carbon emissions, the United Kingdom to improve energy efficiency, while still in the research and development of carbon capture and storage (CCS) technology, that is isolated from large-scale factory combustion of carbon dioxide and store them in the strata. According to reports, this technology can reduce carbon dioxide emissions of about 85% for the use of coal and other fossil fuels provides a new choice. Britain plans to 2030, 60% of carbon emissions to collect, store, Environment Minister Elliot Moree recently pointed out that “carbon mitigation technologies are innovative technologies, is a necessary complement to other emission reduction programs.”

Dr. Wang Qiming

science and technology experts here believed that the world once again into power generation with coal-based fuel by no means accidental, but by a variety of factors contributed to. One of the most important invention of clean coal technology research to make coal use more environmentally friendly and more economical. This is not only a major shift in the industry, but also to prove to the world of science and technology to promote the role of energy use. China is a big country population and energy consumption, coal, long-term energy situation in the country occupies an important position, and therefore should be to keep up with the pace of the world’s scientific and technological progress, step up research and active use of energy-saving environmentally friendly new technologies.

煤炭将重新产生对能源的{sx}燃料，节能的新技术保护环境的帮助

随着世界石油和天然气价格居高不下，全球发电在能源结构的重大变化，煤炭将重新成为新建电厂的{sx}燃料。

据当地媒体报道，全球{zd0}的制造商，发电设备3 -法国的阿尔斯通，德国西门子公司和美国通用电气，最近提出了一项类似的结论，分别。阿尔斯通和西门子的预测显示，在未来10年，平均年发电量为120兆瓦，50亿美元，其中40％的燃煤发电厂单位的数量，而天然气的比例燃煤发电机组设备的订单将下降到25％至30％。阿尔斯通发电总裁朱倍贺说：“电力市场结构将发生根本性的燃料从天然气转变为煤炭的。”通用电气还表示，发电设备的订单将是一个“更为均衡的情景，”天然气与近年来，远远低于占主导地位。

统计表明，1997年至2001年，是天然气发电在世界各地，60％的{sx}燃料，以70％的新电厂使用，而使用煤发电厂只有约20％至30 ％。 2005年，发电燃料转向煤炭的趋势，开始拿出120兆瓦的发电设备订单中，只有20％的形状，至30％的燃气单位。据分析，这个转折点的出现主要有两个因素导致：首先，市场对油价上涨和供应，最近俄罗斯和乌克兰之间的天然气价格争端中的安全问题担忧加剧了这种担忧。目前，许多亚洲国家仍然缺乏稳定的天然气供应渠道，而未来10年，新电厂的订单的一半将来自这些国家。为了确保能源安全，他们将增加煤炭的比重燃煤发电机组。其次，目前的燃煤发电厂减少了许多新技术的排放，已经比较成熟，使燃煤发电造成的负面影响大大降低了环境。

为例英国。科学的能源领域，在世界上英国领导人，特别是在减少二氧化碳排放，清洁能源研究和发展优势。作为一个岛国，英国非常敏感，气候变暖和海平面上的温室气体和碳排放控制水平的提高，还特别注意现已发展了减碳的技术组合，也称为“绿色煤炭技术”或清洁煤已知技术。这项技术的使用可减少二氧化碳排放量的50-60％，使煤炭发电对环境的影响，天然气使用燃煤机组的水平。由于煤炭价格相对便宜，因此清洁煤技术具有广阔的应用前景。为了减少碳排放，英国提高的同时，在研究和碳捕获和储存（CCS）技术，即隔离大规模工厂燃烧二氧化碳储存在地层他们的发展的能源效率， 。据报道，这项技术可以降低对煤炭和其他化石燃料使用的约85％的二氧化碳排放量提供了一种新的选择。英国计划到2030年，60％的碳排放收集，储存，环境部长艾略特莫里最近指出，“碳减排技术创新技术，是一个必要的补充其他减排项目。”

科技此间专家认为，与世界煤炭再次成为发电的燃料，绝不是偶然的，而是由多种因素促成。对清洁煤技术研究领域最重要的发明之一，使煤炭的使用更环保，更经济。这不仅是行业的重大转变，而且还证明，科学技术，促进世界能源利用的作用。中国是一个人口大国和能源消费，煤炭，长期在该国的能源状况占有重要地位，因此应该跟上世界科技进步，加快研究和积极地利用一步步伐节能环保新技术。06.1.27
