Cost competitiveness of green hydrogen production from hybrid solar and wind globally under the effect of global energy shocks

Résumé fourni par la source

Green hydrogen’s role in global decarbonisation depends on its cost and carbon footprint. These vary widely in existing modelling studies, prohibiting a coherent global evaluation. Here, we present underlying data that assesses global levelised costs and embodied carbon for green hydrogen from wind, solar PV and hybrid systems, using spatially granular renewable profiles over 97,000 locations and country-specific costs of capital to optimise electrolyser sizing relative to the on-site renewable capacity. Required costs and carbon intensity of grid imports of electricity to not worsen the average carbon footprint or levelised cost of hydrogen are also assessed. Results of a model sensitivity analysis and the mapping from country index to country name and region are also included here.
