Green Hydrogen: A Clean Energy Solution for Electricity and Heat

Abstract

Hydrogen (H2) is an energy carrier that offers both some of the benefits of fossil fuels and is clean with a low carbon footprint. Production of H2 from the water electrolysis using renewable energy is called green hydrogen and is the preferred pathway for future H2 production. In order to decarbonize the energy sector, green hydrogen must be adapted to existing systems using different technologies. Fuel cells, gas turbines (GTs), and combined heat and power (CHP) systems are the primary applications for hydrogen in power generation. CHP systems are highly efficient and can be employed in buildings, industrial facilities, and district energy systems to provide electrical and thermal energy. Heat pumps integrated with fuel cells are another example of energy-efficient technology. Mixing hydrogen in a specific volumetric ratio improves the resource utilization of the present natural gas heating systems. This chapter focuses on green hydrogen practices in electrical and thermal energy generation applications. © 2024, IGI Global. All rights reserved.
