If ever there were a case of winning all the battles and losing the war, it would be the saga of the long-delayed-and-now-probably-dead Cape Wind offshore wind project in Massachusetts. As I wrote last year

Water is the lifeblood of a thermal power plant. As such, obtaining clean and pure makeup water and dealing with wastewater has been a requirement since the first steam generating unit went into operation. As

Brine, the waste stream of the geothermal power production cycle, is usually considered a nuisance. High in corrosive minerals, even when reinjected, it’s challenging to manage. So when Simbol Inc. showed it had a way to turn this waste stream into a revenue stream by mining it for high-value minerals like lithium, a lot of […]

Although Peru has been one of the best-performing economies worldwide over the last decade, its energy sector is still small in absolute numbers. Consumption levels per capita are low, even by Latin American standards, and demand growth is highly dependent on new mining investments. Successive governments have kept energy prices low; and regional interconnection, which […]

The world will fall short of the goal of providing universal sustainable electricity access by 2030 set by the United Nations and World Bank without “immediate concerted action” by governments, industry, and the international community, according to a survey of utilities around the world conducted by the Global Electricity Initiative (GEI). The GEI is a […]

Proposed U.S. standards for reducing carbon emissions from existing coal-fired power plants rely heavily upon generation-side efficiency improvements. Fuel, operations, and plant design all affect the overall efficiency of a plant, as well as its carbon emissions. This review of the fundamentals of coal plant efficiency, frequent problems that reduce efficiency, and some solutions for […]

An unnamed power company and the U.S. Naval Research Laboratory (NRL) have partnered to test a concept proven to work at a small scale that applies pulsed electron beam technology to slash coal plant nitric oxide and nitrogen dioxide (NOx) emissions. The concept (Figure 3) essentially involves directing electron beams from a cathode into the […]

Thomas H. Adams The American Coal Ash Association (ACAA) welcomed the publication on Dec. 19 of a U.S. Environmental Protection Agency (EPA) Final Rule regulating coal ash disposal as a “non-hazardous”

Germany Approves Plan to Slash Carbon Emissions. Germany’s cabinet on Dec. 3 approved a new policy package to meet ambitious targets that would reduce the nation’s carbon emissions at least 40% by 2020 compared to 1990 levels. The plan proposes that 22 million metric tons of carbon dioxide emissions will be saved by power plants, […]
