Life cycle analysis or assessments (LCAs) are a quintessential tool for power and utility industry professionals and tradespeople. They determine the environmental and financial value of new technologies. Consumer products get the most attention, but LCAs for renewable energy systems (Figure 1) should be discussed more. It is time to synthesize known information to create […]

An iconic coal refuse power plant in West Virginia that burns gob—basically dirt—and pond fines as part of a complex environmental solution to address coal waste is stepping up efforts to improve its efficiency, reliability, and cost reductions by embracing cutting-edge artificial intelligence (AI). American Bituminous Power’s (AMBIT’s) 80-MW Grant Town Power Project—West Virginia’s only […]

Despite a dismal outlook for coal, countries with substantial coal fleets are intensifying efforts to develop new technologies and operational capabilities to improve coal power’s environmental impact

Concrete is the most widely used construction material in the world. One of the key ingredients in concrete is Portland cement. The American Concrete Institute explains that Portland cement is a product obtained by pulverizing material consisting of hydraulic calcium silicates to which some calcium sulfate has usually been provided as an interground addition. When […]

Entergy’s Grand Gulf 1—the largest single-unit nuclear power plant in the U.S.—has thrived for four decades by cultivating a culture of continuous improvement, achieving record-breaking performance

Selective catalytic reduction (SCR) is an important emissions control technology utilized at many coal, biomass, waste-to-energy, and gas-fired power plants. Many items must be considered when designing SCR

Singapore-based Sembcorp Industries, GE Vernova, and Japanese heavy industry firm IHI Corp. will jointly examine potentially retrofitting two GE 9F gas turbines at an 815-MW gas-fired combined cycle power plant in Singapore with ammonia capabilities. The companies on Oct. 25 revealed they signed a non-binding memorandum of understanding (MoU) to assess ammonia combustion capabilities at […]

Seven regional hydrogen hubs spanning Appalachia, California, the Midwest, the Gulf Coast, the American heartland, the Mid-Atlantic, and the Pacific Northwest are poised to receive $7 billion in Infrastructure Investment and Jobs Act (IIJA) funding under the Department of Energy’s (DOE’s) Regional Clean Hydrogen Hubs Program (H2Hubs). The selections, unveiled by the Biden administration on […]

During President Biden’s first year in office, his administration published a document titled “The Long-Term Strategy of the United States: Pathways to Net-Zero Greenhouse Gas Emissions by 2050.” The document says all viable routes to net-zero involve five key transformations. They are: Decarbonize electricity. Electrify end uses and switch to other clean fuels. Cut energy […]

Most propane used in the U.S. today is produced as a byproduct of natural gas processing and crude oil refining, which are not considered “green” technologies. However, renewable propane availability is growing. Renewable propane, like its conventional brother, is commonly made as a byproduct of other fuel production, in its case, often renewable diesel and […]
