A Supercritical CO2–Cooled Small Modular Reactor

A small modular reactor (SMR) system that uses a supercritical carbon dioxide (CO2) Brayton cycle instead of the steam Rankine cycle is under development at the Korea Advanced Institute of Science and


A Breakthrough Carbon-Capturing Algae Project

A research photobioreactor designed to capture significant amounts of carbon dioxide (CO2) from power plant flue gas for high-density algae cultivation is showing promise. The bioreactor patented by California-based algal firm PHYCO2 is undergoing a multi-year trial at Michigan State University’s (MSU’s) T.B. Simon Power Plant, a co-generation plant that provides steam, heat, and power […]

EPA Motions Court for Weighty Changes to Final Coal Ash Rule

  A recent motion filed by the Environmental Protection Agency (EPA) asking a federal court to remand parts of its final coal combustion residuals (CCR) rule could have major new consequences for the power sector if upheld, an expert has said. In its 16-page motion filed on April 18, the agency asked the U.S. Court of Appeals […]

Environmental Experts Underscore Clean Power Plan Uncertainty

  Even if the Clean Power Plan (CPP) doesn’t overcome legal challenges, it is likely that many states will implement carbon-curbing measures set down by the rule, some panelists said at the Environmental Mega Session at the ELECTRIC POWER 2016 conference in New Orleans on April 19. The Rule’s Shaky Legal Standing The rule is […]


[UPDATED] EPA Stands Ground on MATS with Final Cost Consideration

Public benefits offered by the Mercury and Air Toxics Standards (MATS) far outweigh the costs, the Environmental Protection Agency (EPA) said as it released a review of the 2012-finalized rule’s cost implications. The final cost consideration—released just days before power plants that received a one-year extension must come into compliance with the rule—was prompted by […]

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. The House Energy and Water Subcommittee, a panel of the Appropriations Committee, passed a $37.4 billion bill to fund the DOE as well […]


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 […]


Aliso Canyon Gas Leak May Imperil Summer Reliability, CAISO Says

In a joint report issued April 5, a group of California agencies and utilities said that if the Aliso Canyon natural gas storage facility north of Los Angeles cannot be returned to service after a major leak this past winter, repeated gas curtailments could occur this summer, leading to significant loss of generating capacity in Southern […]


Air Emissions Tampering Leads to Felony Charges at Power Plant

The owner and management company of the Berkshire Power Plant—a 252-MW natural gas–fired combined cycle plant located in Agawam, Mass.—agreed to plead guilty on March 30 to felony charges that the companies violated and conspired to violate the federal Clean Air Act. The indictments against Berkshire Power Co. (BPC), the owner of the plant, and […]
