"Global Green Hydrogen Economy: Electricity Competition and Land-Use Change" by Chen, Chun-Yu and Ruth Delzeit Abstract Hydrogen is emerging at the center of the global energy discourse as an energy carrier with a great potential to reshape the global energy transition. Produced through the electrolysis process with renewable sources, green hydrogen provides a low-carbon alternative to decarbonize hard-to-electrify sectors and provides flexibility to be stored and transported across regions. An acceleration of the green hydrogen production is projected by 2050, which necessitates a significant amount of renewable sources and land endowment globally, bringing about considerable land-use and economic implications for sustainability. The objective of this study is to evaluate the impact of the expected expansion of solar electricity for the global green hydrogen production on land-use change, as well as the associated economic impacts on the electricity market and agricultural market. A global recursive-dynamic CGE model, CGEBox, with an extension of hydrogen energy, is employed to examine the interlinkages across the energy and agricultural sectors through land allocation. Additional disaggregated information of hydrogen production, the solar electricity sector, and solar land factor with the GTAP 11- Power datasets are used in the model. We apply scenarios on increased hydrogen demand and increased solar energy inputs by 2050 and compare this to a baseline. The baseline is constructed through GTAP-based Recursive Dynamic Economic Model with exogenous projections of Shared Socioeconomic Pathway 1. The analysis focuses on the dynamics and interlinkages of the land factor and the corresponding responses from the energy and agricultural sectors, led by the increasing demand for hydrogen products, alongside an evaluation of competitive dynamics between green hydrogen and renewable electricity. The anticipated results of this study could facilitate the knowledge of the sustainability implications of new energy technology and future strategies in green hydrogen development. |
