The government of Estonia has signed a Memorandum of Understanding (MoU) for what would be the Eastern European country’s first pumped hydro energy storage (PHES) facility.

BESS with up to 4-hour duration helping to meet summer peaks, but long-duration energy storage may be key to managing winter demand.

Closed-loop pumped hydro energy storage (PHES) has fewer emissions associated with its development, construction and use than other leading options for large-scale energy storage.

The US National Renewable Energy Laboratory (NREL) has updated its long-term battery energy storage system (BESS) costs through to 2050, with costs potentially halving over this decade.

Energy storage costs in the US grew 13% from Q1 2021 to Q1 2022, said the National Renewable Energy Laboratory (NREL) in a cost benchmarking analysis.

Hydrogen storage company GKN Hydrogen, gas utility SoCalGas and the US Department of Energy’s National Renewable Energy Laboratory are collaborating on a new green hydrogen storage solution.

Energy storage poised for “rapid growth” in US, with between 130GW to 680GW diurnal storage capable of integrating 80% share of renewables by 2050.

Energy storage will play an important role in US power systems between now and 2050, offering the opportunity to displace fossil fuels with low-cost renewable energy and balancing supply and demand across multiple regions. 

In this episode of the Solar Media Podcast, we hear the verdict directly from those who were there at COP26.

The installed cost of solar PV, solar-plus-storage and standalone battery energy storage in the US was reduced across all market segments between 2020 and 2021, with the biggest drop seen in the utility-scale segment.
