Techno-economics of Green Hydrogen: Present Trends and Future Prospects

Techno-economic aspects of green hydrogen production play a significant role in shaping the development and deployment of new hydrogen facilities. Comprehensive analyses of cost components that impact the levelized cost of green hydrogen have become increasingly important for supporting investment strategies and production planning processes. Furthermore, these analyses have proven valuable in decision-making processes related to the establishment of support mechanisms that ensure the sustainable energy transition of national and local power, heating, and transport sectors. This chapter identifies and discusses various metrics and factors affecting the nascent green hydrogen market. Additionally, this chapter is devoted to identifying the current economic trends and future prospects of green hydrogen production technologies, specifically alkaline, proton exchange membranes, and solid oxide water electrolysis powered by renewable energy sources. Finally, the chapter analyzes existing policy efforts and various policy instruments to promote green hydrogen as a critical element in the decarbonization of global economies.
