New Solar + Battery Price Crushes Fossil Fuels, Buries Nuclear

“This is the lowest solar-photovoltaic price in the United States,” said James Barner, the agency’s manager for strategic initiatives, “and it is the largest and lowest-cost solar and high-capacity battery-storage project in the U.S. and we believe in the world today.” Source: New Solar + Battery Price Crushes Fossil Fuels, Buries Nuclear

The role of pumped-hydro storage in a 100% renewable world

If the demand for electricity in Juneau were to grow while the region grappled with a handful of low precipitation years, could the existence of a pumped-hydro storage system prevent facilities like Greens Creek, the Federal Building and others from having to burn thousands of gallons of diesel fuel for their energy needs?

Pumped Hydro Energy Storage Archives – News from Australia

Pumped storage is an essential solution for grid reliability, providing one of the few large-scale, affordable means of storing and deploying electricity. Pumped storage projects store and generate energy by moving water between two reservoirs at different elevations. Essentially, this low tech concept creates a simple land and water based battery. This info from Australia…

Stacking concrete blocks is a surprisingly efficient way to store energy

A startup called Energy Vault thinks it has a viable alternative to pumped-hydro: Instead of using water and dams, the startup uses concrete blocks and cranes. While everyone else is out looking for high-tech, futuristic battery innovation, there may be real value in thinking about how to apply low-tech solutions to 21st-century problems.
