煤炭是一種豐富的本土能源，為美國(guó)提供了近50%的電力。到2030年，電力需求預(yù)計(jì)將增長(zhǎng)30%以上。根據(jù)EIA的分析，預(yù)計(jì)只有增加煤炭使用量才能實(shí)現(xiàn)這一目標(biāo)。此外，中國(guó)近一半的電力基礎(chǔ)設(shè)施都有30年以上的使用年限，其中相當(dāng)一部分的使用年限是30年的兩倍。這些老化的設(shè)施需要或即將需要大量的翻新或更換。為了滿(mǎn)足國(guó)家日益增長(zhǎng)的電力需求，還必須增加電力供應(yīng)。因此，美國(guó)能源部預(yù)計(jì)，至少在未來(lái)幾十年，美國(guó)近一半的電力需求將繼續(xù)由煤炭供應(yīng)。鑒于環(huán)境管理意識(shí)的增強(qiáng),同時(shí)滿(mǎn)足要求可靠和具有成本效益的電力供應(yīng),這顯然是公共利益國(guó)家的能源基礎(chǔ)設(shè)施的升級(jí)的最新和最先進(jìn)的商業(yè)可行性技術(shù)來(lái)達(dá)到更大的效率,環(huán)境績(jī)效,costcompetitiveness。但是，要使這些先進(jìn)技術(shù)被接受和復(fù)制到發(fā)電部門(mén)，必須首先展示這些技術(shù)(即，按照工業(yè)標(biāo)準(zhǔn)設(shè)計(jì)和建造，并在工業(yè)條件下大規(guī)模運(yùn)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).
