AI Summary

A recent development in Finland has shown promise in reducing emissions without relying on rare earth materials. The country's sand battery has reportedly achieved a 70% reduction in emissions, a notable achievement in the pursuit of cleaner energy. This technology has the potential to address the energy storage capacity gap in Europe, which has been exacerbated by the continent's reliance on imported fossil fuels. The European Union's efforts to increase solar and wind capacity have been hindered by a lack of energy storage capacities, creating vulnerabilities for the grid and energy markets.
