EPRI Informs Efforts to Extend Nuclear Plant Licenses in Japan Drawing on decades of technical research on the U.S. nuclear fleet, EPRI research supported a successful effort by a Japanese utility to extend the operating license of three of its nuclear units. Many nuclear plants in Japan are approaching 40 years of age—the endpoint of their original licenses. The Japanese regulator has endorsed a framework, similar to the International Atomic Energy Agency’s International Generic Aging Lessons Learned (IGALL) program, to support up to 60 years. The IGALL identifies areas in nuclear plants that require aging management programs, providing ...

The Health and Safety Benefits of Electrifying the Workplace
An EPRI Quick Insights brief points to health and safety benefits of in commercial and industrial facilities. Examples include:
  • Replacing combustion engine–driven forklifts with electric forklifts can reduce noise pollution, refueling hazards, and worker exposure to carbon monoxide.
  • Replacing chemical water treatment with electric processes such as ultraviolet rays and ozone removes harmful chemicals from the workplace and eliminates worker exposure.
  • Replacing natural gas fryers and griddles with electric equipment in commercial kitchens reduces ambient temperatures and eliminates exposure to open flames and combustion by-products such as ...

The Rise of Microgrids Could Be Good News for Fuel Cells
After decades of high expectations and low adoption, stationary fuel cells may be poised for market growth in distributed generation applications, according to an EPRI Strategic Intelligence Update. Fuel cells offer reliable, 24/7, quiet operation along with the highest efficiency and lowest emissions of all fuel-based generation technologies. But hydrogen fuel management along with fuel cells’ high upfront costs, low returns, and slow ramp rates relative to engines, turbines, and other combustion-based technologies have proven to be key barriers to adoption. While those challenges remain significant, ...

EPRI Simulates a Flexible, Reliable Distribution Feeder with High-Penetration Renewable Resources
In the laboratory, EPRI successfully demonstrated an open architecture to coordinate, control, and dispatch distributed energy resources and to support grid operations. Results suggest that with a robust command-and-control architecture, utilities can use high penetrations of distributed renewables for voltage control, transmission support, and other grid services. At the National Renewable Energy Laboratory, EPRI built an analog simulator to model a 10-mile distribution feeder connected to hundreds of distributed energy and demand response resources. Standard messages on a enabled interoperability among the resources, and EPRI ...

Despite great technological advances over the past two decades, an EPRI study concludes that fuel cell electric vehicles still lack the low cost and long life needed for commercial viability, with no real prospects for market share before the mid-2020s. Since the early 1990s, several major automobile manufacturers have invested billions of dollars to develop for electric vehicles. Government R&D programs in the United States, Japan, and Europe have led to prototypes and early-production vehicles with good drivability. Drawing on nonproprietary information from technical literature, conferences, developers, and fabricators, researchers compared the cost and endurance of current fuel ...
