The DOE today announced it would fund 10 projects aimed at developing advanced technologies for capturing carbon dioxide (CO₂) from coal combustion. The projects, valued at up to $67 million over three years, focus on reducing the energy and efficiency penalties associated with applying currently available carbon capture and storage (CCS) technologies to existing and new power plants.

A study released last week by the nonprofit American Council for an Energy-Efficient Economy (ACEEE) concludes that smart metering initiatives alone are not enough to save energy.

Cap-and-trade programs are featured in at least two U.S. legislative proposals to reduce carbon emissions, usually by around 80% by 2050 using a 2005 baseline. The benefits that accrue from the immense investment required to reach these goals are nebulous and don’t occur until decades after the investment. Based on my back-of-the-envelope analysis, the cost-benefit ratio of these proposals does not pass a cursory cost-benefit analysis.

American Electric Power’s (AEP’s) Cardinal Power Plant Unit 3 cooling tower in Brilliant, Ohio, was coated and lined in the spring of 2008 by a team of coatings professionals that included the plant’s project and coatings engineering staff, Sherwin-Williams (coatings supplier), Cannon Sline Industrial (contractor), and OTB Technologies (third-party inspector). The team completed the project in just 11 weeks through damp springtime conditions in the Ohio River Valley.

In April, Solvay Chemicals Inc. commissioned a new facility that uses an innovative process to recover and transform sodium carbonate waste streams into a market-grade sodium bicarbonate used in air emissions control.

Safety is the imperative for any construction project, and Duke Energy’s 630-MW Edwardsport integrated gasification combined-cycle station in Knox Country, Ind., is no exception.

Abengoa Solar in early May began commercial operation of Solnova 1, the company’s first 50-MW parabolic trough plant. Covering 980,000 square feet with mirrors requiring an area totaling 280 acres (Figure 2), it is one of five planned concentrating solar power (CSP) plants to be built at the Solúcar Platform in Spain. All will use a technology developed by Abengoa with experience gained from a trough pilot built in 2007. Solnova 1 will also be equipped to burn natural gas if sunlight is weak.

An Australian sewage plant this April began using treated wastewater falling down a 60-meter (m) shaft to produce its own power.

The gas-rich emirate of Qatar, holder the world’s third-largest gas reserves, inaugurated another massive 2,000-MW gas power plant in the industrial city of Mesaieed, south of the capital Doha this May.

While Europe’s offshore wind sector has taken off, interest is resurging in marine energy. The UK’s Crown Estate took the major step this March, for example, of awarding leasing rights to 10 wave power projects to develop generation in Scotland’s Pentland Firth and Orkney waters of the North Sea.
