  • Fuel Cells Could Be a “Game-Changer” for Carbon Capture

    Fuel cells powered by natural gas, biogas, and hydrogen are a rapidly expanding option for distributed generation, with fuel cell­­–based power plants being deployed in capacities into tens of megawatts. But as the technology improves and costs begin to scale, opportunities for other applications are being explored. One such application may even go beyond power […]

  • Supreme Court Strikes Down Maryland Power Plant Subsidies

    In a unanimous ruling, the U.S. Supreme Court upheld a lower court decision that a program Maryland initiated in 2012 to subsidize power plant construction impermissibly invaded the Federal Energy Regulatory Commission’s (FERC’s) authority over interstate power markets. The case, Hughes v. Talen Energy Marketing, grew out of a decision by the Maryland Public Service […]

  • House, Senate Subcommittees Pass Energy Appropriations Bills

    Subcommittees of the U.S House of Representatives and the U.S. Senate separately advanced appropriations bills that lay out funding priorities for the Department of Energy (DOE) and other energy-related measures for 2017.

  • Is EOR a Dead End for Carbon Capture and Storage?

    In April’s editorial, “When Technology Tails Wag Power Dogs,” Editor Gail Reitenbach mused about whether the use of captured carbon dioxide (CO2) for enhanced oil recovery (EOR) represents a viable way forward for carbon capture, use, and sequestration (CCUS). This is a subject both of us have covered in various ways over the past few […]

  • Gas Combined Cycle Capacity Factors Beat Coal for First Time Ever

    The average capacity factor for U.S. natural gas–fired combined cycle power plants (CCPPs) exceeded that for coal-fired plants in 2015 for the first time since the Energy Information Administration (EIA) has been keeping records, the agency noted on April 4. Gas generation exceeded coal generation for most of 2015, though coal ended slightly ahead for […]
