A novel technique called Underground Gravity Energy Storage turns decommissioned mines into long-term energy storage solutions, thereby supporting the sustainable energy transition.

With the rapid reduction in the costs of renewable energy generation, such as wind and solar power, there is a growing need for energy storage technologies to make sure that electricity supply and demand are balanced properly. IIASA researchers have come up with a new energy storage concept that could turn tall buildings into batteries to improve the power quality in urban settings.

Despite successes in reducing poverty globally in the last two decades, almost one billion people are still living without access to reliable and affordable electricity, which in turn negatively affects health and welfare, and impedes sustainable development.

Efforts to reduce greenhouse gas emissions in the energy sector could lead to greater pressure on water resources, increasing water use and thermal water pollution. Dedicated adaptation measures will be needed in order to avoid potential trade-offs between the water and climate change impacts of the energy system.
