Sodium-ion batteries: Europe’s green power boost

The United Nations predicts that European renewable energy usage will double by 2027. Germany set a new record by generating 57.7% of its net power from renewables in the first half of 2023. One of the biggest barriers to a 100% renewable grid however, is the variability of renewables. Wind and the sun are not constant, and the windiest and sunniest areas are often far from many cities.
