Reliable and affordable electricity systems based on variable energy sources, such as wind
and solar may depend on the ability to store large quantities of low-cost energy over long …

Summary We use 36 years (1980–2015) of hourly weather data over the contiguous United
States (CONUS) to assess the impact of low-cost energy storage on highly reliable electricity …

Policies in the US increasingly stipulate the use of variable renewable energy sources,
which must be able to meet electricity demand reliably and affordably despite variability. The …

Deeply decarbonizing electricity production will likely require that low-carbon sources meet
energy demand throughout days, years, and decades. Wind and solar energy are possible …

We model many combinations of renewable electricity sources (inland wind, offshore wind,
and photovoltaics) with electrochemical storage (batteries and fuel cells), incorporated into a …

With declining costs of battery storage, there is growing interest to deploy them in power
systems to provide multiple grid services that directly support integration of variable …

Renewable energy sources, such as wind and solar, have vast potential to reduce
dependence on fossil fuels and greenhouse gas emissions in the electric sector. Climate …

Energy storage at all timescales, including the seasonal scale, plays a pivotal role in
enabling increased penetration levels of wind and solar photovoltaic energy sources in …

In the context of 100% renewable electricity systems, prolonged periods with persistently
scarce supply from wind and solar resources have received increasing academic and …

High cost and technical immaturity of bulk (multi-hour) electricity storage (BES) systems are
often cited as major hurdles to increasing the penetration of intermittent renewables. We use …
