Abstract

Governments across the world have set carbon neutrality goals in response to growing climate concerns. To achieve carbon neutrality, large-scale variable renewable energy must be deployed, and energy intensive sectors such as transportation and industry must switch to carbon neutral alternatives. Hydrogen has been seen as a solution both in the industry and transport sectors. The objective of this paper is to investigate the role of power – to – hydrogen in achieving carbon neutrality in an energy and industrial system containing large-scale variable renewable energy.
This contribution models the effects of substituting fossil hydrogen in industry with renewable hydrogen and introducing hydrogen to replace fossil fuel use in steel industry and transportation sectors on a highly renewable power and heat system. This was achieved by using the EnergyPLAN – software to provide a case study of a highly renewable Finnish energy system set in 2040. Introducing the hydrogen increased electricity consumption by 31.87 TWh/a, but significantly reduced the CO2 emissions by 71.5 % and fossil energy usage by 72.6%. Different electrolyser generation profile was investigated, but additional investments needed in hydrogen storage capacity rendered this uneconomical.
