Wind, solar deliver stunning 98 percent of new U.S. power capacity in January, February

Renewables to provide 69 percent of new capacity by March 2021, as dozens of coal plants are retired By JOE ROMM on Climate Progress APR 24, 2018 WIND TURBINES AND SOLAR PANELS IN CALIFORNIA, 2013. CREDIT: KEVORK DJANSEZIAN/GETTY IMAGES Solar and wind power was responsible for a remarkable 98 percent of all new U.S. power generation capacity that came online in the first two …

Supercapacitor-based energy storage for microgrids avoids over-sizing. Micro-grid engineering becoming a macro profession.

Supercapacitor-based energy storage, on the other hand, is much simpler. This technology stores energy on the surface of the electrolyte, which means there is no chemical reaction. “Electrical energy comes in and is stored as electrical energy. It releases electrical energy back into electricity when discharged,” Ghani explained.   Still supercapacitor-based energy storage hasn’t been used before because it has its …

Bloomberg reports that the combination of solar power plants and grid scale battery storage is now cheaper than natural gas and utility companies all across the US are starting to notice

February 15th, 2018 by Steve Hanley, Clean Technica  First there was coal. You burned it to make steam, then the steam was used to turn generators to make electricity. For more than a century, coal was the power that made electrical energy possible for most of the world. But coal has a problem. When it burns, it releases massive quantities of carbon …

V2X: New project trials EV to building energy storage

 Apr 03, 2018  Priyanka Shrestha on Energy Live News  Image: Shutterstock A new project is trialling the use of electric vehicle (EV) batteries as energy storage for office buildings. ENGIE, Hitachi Europe and Mitsubishi Motors linked the first “vehicle to everything” (V2X) charger to the French utility’s office building in the Dutch city of Zaandam. Hitachi’s V2X charger can not only recharge EVs but also discharge the energy …

Valuing resilience and reduced load with solar plus storage

Utility Dive, 15 Feb 2018 As Hurricane Irma receded last September, thousands of Floridians sheltered in 115 well-lit schools, drinking hot coffee and communicating with the world through cell phones charged by solar-plus-storage systems. Funded by a $9.8 million 2009 Recovery Act grant, the solar-plus-storage systems powered the schools despite the overcast weather, while 6.7 million utility customers had no electricity. Like last year’s hurricanes …

California regulators first to allow multiple revenue streams for energy storage. Also, Maryland Storage Tax Credit pays 30%

Feb. 13, 2018, Utility Dive The state has approved rules that increase the ways for energy storage systems to make money, for example, through frequency regulation, capacity or spinning reserve services.  The California Public Utilities Commission in mid-January became the first state regulator to issue revenue stacking rules for energy storage projects, but the rules could be more of a starting point …

Solar and batteries are edging out gas, and batteries are becoming bigger for Tesla too

Bloomberg, Feb 2018 Natural gas is getting edged out of power markets across the U.S. by two energy sources that, together, are proving to be an unbeatable mix: solar and batteries. In just the latest example, First Solar Inc. won a power contract to supply Arizona’s biggest utility when electricity demand on its system typically peaks, between 3 p.m. and 8 p.m. The panel …

Many ways to avoid blackouts and save money in the shift to 100% renewable, reliable energy, worldwide

Researchers propose three separate ways to avoid blackouts if the world transitions all its energy to electricity or direct heat and provides the energy with 100 percent wind, water and sunlight. The solutions reduce energy requirements, health damage and climate damage. Key elements of the solution applicable to different cases are to Produce heat directly from solar and geothermal heat …

Rooftop Solar + Storage = Hurricane Energy Resiliency. Roof-mounted systems and nearly all ground-mounted systems in Florida came through Hurricane Irma

Clean Technica, Feb 2018, by Danny Parker Figure 1: Hurricane Irma Bears Down on Florida on September 8th, 2017. (NOAA) Improving Storm Resiliency with Rooftop Solar & Electrical Storage One series of complaints in the wake of Hurricane Irma came from some individuals who had installed solar electric PV systems and then were unable to use the produced solar power …
