Reversing Climate Change with Nuclear Power [PODCAST]

According to the Energy Impact Center, a Washington, D.C.-based research institute focused on deep decarbonization, CO2 emissions “must go net-negative by 2040, globally across all energy sectors” to begin countering climate change. The only way it sees to accomplish this is to “produce energy inexpensive enough to make carbon negative fuels that compete with fossil […]

The POWER Interview: New Directions for Aeroderivative Gas Turbines at PWPS 

In a recent interview, Raul Pereda, president and CEO of PW Power Systems (PWPS), talked to POWER about the company’s long legacy as a gas turbine manufacturer, advancements in technology it has achieved over the past 60 years, and new applications for its turbines within a transitioning energy system.  No one can read a history […]

EPA Delayed on Proposed ELG Revisions for Steam Power Plants

The Environmental Protection Agency (EPA) is behind on its proposed revisions to the Obama administration’s effluent limitations guidelines (ELGs) for steam electric power plants.  In an e-mail to POWER on July 9, the EPA confirmed that the agency was still “working expeditiously” to complete the proposed rule, and it has yet to submit it to […]

A Brief History of GE Gas Turbines

July marks two important milestones that set gas-fired generation on its course to becoming a dominant form of power generation: commercial operation of the world’s first industrial gas turbine in Neuchâtel, Switzerland, in 1939, and commercial operation of the first gas turbine in the U.S. used to generate electric power—a 3.5-MW General Electric (GE) unit […]

Coal Unit CCUS Retrofits More Economic Than Many Alternatives, NETL Study Suggests

Adding carbon capture, utilization, and storage (CCUS) to two Xcel coal units in Colorado that are slated to be retired by 2025 would push up the cost of power if compared with replacement with wind/storage hybrids. But CCUS, which generates revenues, would still work out to be cheaper than other alternatives mandated under the company’s […]

Distributed Energy Award Goes to Unique Hog Farm Microgrid

Power from pig manure is not a public relations stunt, but rather, it’s an innovative solution to several farm challenges. Installing lagoon covers not only reduces odors and eliminates rainwater ingress

Hydropower Is Vital to Africa’s Future

Africa has a number of power supply challenges, many of which can be overcome with renewable energy. Foremost among the options is hydropower. While large projects can meet stiff resistance in the development

A Clean Sweep for Invasive Mussel Biofouling

The rapid proliferation of dreissena rostriformis bugensis—the quagga mussel—has major implications for power plant reliability. The U.S. Bureau of Reclamation installed a groundbreaking solution at Parker
