Future Potential of Large-Scale Grid-Connected and Hydrogen Based Photovoltaic Power Generation in Finland

摘要

The paper describes a pre-feasibility assessment on the potential of large-scale photovoltaic power generation in Finland ranging in time from 1990 up to 2020, and on the possibility of converting solar electricity into hydrogen to provide energy storage and transmission. Special attention is paid to the possible use of existing natural gas facilities for hydrogen or for a mixture of natural gas and hydrogen. The paper starts with an extensive survey on international activities in the PV-hydrogen technology supplemented by a review on future prospects in photovoltaic technology and hydrogen energy systems. These are followed by detailed scenarios on the potential of large-scale PV-technology in the future Finnish energy supply system.
