Energy materials for energy conversion and storage: focus on research conducted in Korea

Fossil fuels are widely used around the world, resulting in adverse effects on global temperatures. Hence, there is a growing movement worldwide towards the introduction and use of green energy, i.e., energy produced without emitting pollutants. Korea has a high dependence on fossil fuels and is thus investigating various energy production and storage technologies for producing and using green energy. Renewable energy technologies are essential for producing green energy, and energy storage technologies are necessary for its effective use. In Korea, the renewable energy technologies of most interest are solar power generation and fuel cells, followed by energy storage, transportation. This review intends to provide information about the energy materials currently being researched to develop these energy technologies.
