Humans have to deal with environmental and fuel availability challenges in a complex socio-economic situation. To slow down global warming caused by greenhouse gases, especially CO2, and find an alternative to our dependence on fossil fuels, hydrogen is considered the most promising energy carrier due to its high volumetric energy density (33.33 kWh/kg H2) [1]. Hydrogen can be integrated into the power-to-gas-to-power (PtoGtoP) concepts on a large scale and for long periods to balance energy supply and demand and to achieve carbon neutrality targets. Nonetheless, problems still need to be solved, such as elevated cost, intermittent energy inflows, and low efficiency [1,2]. Such low efficiency (15 to 40 %) is owing to energy conversion and storage losses [1,2]. Storing hydrogen in solid form as hydride compounds is an energy-efficient and compact solution that offers large hydrogen storage capacities under mild pressure and temperature conditions [1-4]. So-called metal hydrides (MH) work at room temperature and in a broad range of pressures from 1 to over 500 bar (depending on the material's composition), and with volumetric hydrogen density over 50 kg H2/m3, and require less energy as compared with high-pressure or liquid hydrogen storage [1-4]. This work is about developing hydride-based materials and designing a renewable energy system for hydrogen storage and CO2 conversion [1-6]. First, an overview of the hydrogen technology based on hydrides is given. Then, the design of hydridebased materials for hydrogen storage, compression, and CO2 capture and conversion is discussed. Examples of synthesis, characterization, and applications of chemical and interstitial (room temperature) hydrides are shown. Finally, the development of hydride-based renewable energy systems for PtoGtoP utilization and CO2 conversion is described. This overview aims to provide the potential of the hydride technology for implementing new concepts to transition toward the emerging eco-friendly hydrogen technology.
