– A simple and efficient way for large scale and long duration energy storage.

Renewable energy technologies have come a long way since the first solar panels and wind turbines were built to harness the energy from sun and wind to meet the ever increasing energy demands of mankind. Advancements in renewable technologies and mushrooming of bigger and larger wind and solar farms are slowly reducing the unit cost of power generated using renewable resources. Also, the contribution by renewable technologies in many countries energy pie chart is growing in size, and is slowly reducing the world’s dependency on fossil fuels for electricity.
