  • GAO finds impediments to CCS deployment

    An underdeveloped and costly CO2 capture technology, as well as regulatory and legal uncertainties over CO2 capture, injection, and storage, are the some of the more critical factors that impede carbon capture and storage (CCS) deployment in the U.S., the Government Accountability Office (GAO) — a congressional investigative arm — has reported. In its report, […]

  • Top Plants: San Cristobal Wind Project, Galapagos Islands, Ecuador

    The Galapagos Islands, home of the unusual flora and fauna that inspired naturalist Charles Darwin’s groundbreaking work on evolution, are striving to promote clean energy that protects the area’s unique biodiversity. Part of that effort is the 2.4-MW San Cristobal Wind Project, which displaces diesel-powered electricity generation. This new energy source will cut greenhouse gas emissions and reduce the risk of devastating diesel-fuel tanker spills in a highly protected environment.

  • Advanced batteries supply ancillary services

    For the power engineer, delivering an instantaneous and consistent power supply can be an elusive goal. Yet without it, grid frequency regulation is impossible. Today, frequency regulation is an ancillary service bought by the hour, the day prior to utilization, and dispensed on an as-needed basis by dispatch communiqués and provided by the ancillary service […]

  • The return of the Clipper Liberty wind turbine

    The Steel Winds project in Lackawanna, New York, was selected as a POWER 2007 Top Plant because of its unusual location (a former steel mill and Superfund site) and because it was the first commercial deployment of the Clipper Windpower 2.5-MW turbine. That report was written just as the project entered commercial service but before a major gearbox problem was identified. For many new designs, it isn’t a question of if problems will occur but of how the manufacturer responds when problems inevitably do occur. For its handling of Liberty’s problem, Clipper Windpower gets an "A."
