Analysts: Coal Generation Will Plummet More Than 70%

About half the world’s power will be generated by wind and solar resources by 2050. Generation from coal will drop more than 70% from today’s levels. That’s according to research from energy analysts published June 19 in the “New Energy Outlook 2018” (NEO) from Bloomberg New Energy Finance (BNEF). The NEO report outlines information from […]

Investments in Renewables Dwarf New Coal, Gas Generation

A report from groups including the United Nations environmental arm and Bloomberg New Energy Finance (BNEF) shows renewable energy installations were responsible for 61% of the world’s net power capacity additions in 2017, more than double the new-builds from fossil fuel-powered generation. The Global Trends in Renewable Energy Investment 2018 report, compiled by BNEF, the […]

Overcoming IIoT, Edge Networking Challenges

As power plants and substations become more connected, the need for rugged networking equipment built to withstand tough conditions is amplified. The military has already gone through the growing pains, so

A major demonstration. The team of SwRI, GTI, and GE Global Research will design, build, and operate a 10-MWe pilot plant for demonstrating supercritical carbon dioxide (sCO2) power cycles. The plant, shown here in an engineering concept drawing, will be located at SwRI’s headquarters in San Antonio. Courtesy: Southwest Research Institute

Game-Changing Supercritical CO2 Cycles Are Closer to Commercialization

Supercritical carbon dioxide (sCO2) cycles—which are inching closer to commercial applications for waste heat recovery, concentrating solar power, nuclear, and fossil energy—offer higher thermal efficiencies and power density than conventional steam Rankine and Air Brayton cycles in use today for power generation. But to realize these potentially game-changing cycles, common challenges associated with turbomachinery must […]

Utilities Prepare for Simulated Attack on U.S. Power Grid

Utilities across the country are gearing up for an attack on the power grid November 15 and 16. Thankfully, it’s only a drill. But in the event of an actual emergency, a real physical and cyberattack on the U.S. electricity infrastructure, GridEx IV—a biennial exercise conducted by the North American Electric Reliability Corp. (NERC)—will help […]
