Energy Storage : A Missing Piece of the Puzzle for the Self-Sufficient Living

The purpose of this publication is to update the state of the art research and future sights for hydrogen and battery based energy storage systems. Even though batteries are well known technology and hydrogen have been called energy carrier of the future for decades now, the development of large-scale electrical energy storages has been challenging. This study takes a look at the current situation of energy storage markets. In this report, there are described current technologies to generate, store and convert hydrogen back to electricity, and furthermore common battery technologies are presented. It includes current market status reports for both storage technologies and comparison between them. This publication is part of cross-border project Artic Energy - Low Carbon Self-Sufficient Community. The goal of the project is to create a model for self-sufficient, low carbon community using local renewable energy sources in the arctic region. Developed model can be used as a planning tool for all regions, which have the same circumstances than the project area to follow EU- and national level climate and energy strategies. The project is funded by EU-program Interreg Nord, Regional Council of Lapland, Länsstyrelsen Norbotten and Interreg-program in Norway
