资料简介
煤炭是一种丰富的本土能源，为美国提供了近50%的电力。到2030年，电力需求预计将增长30%以上。根据EIA的分析，预计只有增加煤炭使用量才能实现这一目标。此外，中国近一半的电力基础设施都有30年以上的使用年限，其中相当一部分的使用年限是30年的两倍。这些老化的设施需要或即将需要大量的翻新或更换。为了满足国家日益增长的电力需求，还必须增加电力供应。因此，美国能源部预计，至少在未来几十年，美国近一半的电力需求将继续由煤炭供应。鉴于环境管理意识的增强,同时满足要求可靠和具有成本效益的电力供应,这显然是公共利益国家的能源基础设施的升级的最新和最先进的商业可行性技术来达到更大的效率,环境绩效,costcompetitiveness。但是，要使这些先进技术被接受和复制到发电部门，必须首先展示这些技术(即，按照工业标准设计和建造，并在工业条件下大规模运作)。
Coal is an abundant and indigenous energy resource and supplies almost 50 percent of the United States’ electric power. Demand for electricity is projected to increase by more than 30 percent by 2030. Based on analyses conducted by the EIA, it is projected that this power increase can only be achieved if coal use is also increased. Furthermore, nearly half of the nation’s electric power generating infrastructure is more than 30 years old, with a significant portion in service for twice as long. These aging facilities are - or soon will be - in need of substantial refurbishment or replacement. Additional capacity must also be put in service to keep pace with the nation’s ever-growing demand for electricity. Therefore, DOE expects that nearly half of the nation’s electricity needs will continue to be served by coal for at least the next several decades. Given heightened awareness of environmental stewardship, while at the same time meeting the demand for a reliable and cost-effective electric power supply, it is clearly in the public interest for the nation’s energy infrastructure to be upgraded with the latest and most advanced commercially viable technologies to achieve greater efficiencies, environmental performance, and costcompetitiveness. However, to realize acceptance and replication of these advanced technologies into the electric power generation sector, the technologies must first be demonstrated (i.e., designed and constructed to industrial standards and operated at significant scale under industrial conditions).
