The Czechs have developed a technology for storing energy in sand
A team of Czech scientists has devised a system for storing energy in sand. With global markets facing escalating energy costs and the pressing demand for sustainable alternatives, this innovative solution holds promise on multiple fronts.
Energy storage in sand – how does it work?
A sand-based energy storage system has the potential to cater to the energy requirements of diverse settings, ranging from residential households to large industrial enterprises.
The operating principle of sand energy storage is straightforward: electricity, typically sourced from renewable energy, heats the sand, thereby creating a reservoir of thermal energy. This stored heat can subsequently be harnessed and converted back into electricity or utilized directly for heating purposes.
Notably, this solution boasts minimal operating costs and eliminates the need for scarce raw materials typically used in chemical energy storage facilities.
Czech energy goals
On January 13, 2020, the Czech Republic government approved its national energy and climate plan, slated for implementation from 2021 to 2030. Crafted by the Ministry of Industry and Trade, this plan marks a significant shift in the country’s energy landscape, prioritizing the utilization of renewable energy sources.
Compared to the energy assumptions outlined in 2015, the new strategy places greater emphasis on renewable energy. Despite the European Commission’s recommendation of achieving a minimum 23% share of renewables in total energy production and consumption within the decade, the Czech Republic’s plan aims for 22% by 2030.
