HyUnder - Hydrogen Underground Storage at large scale, Part Ⅰ: General project results (European Level)

摘要

Hydrogen Underground Storage has developed as important topic in the context of Power-to-Gas schemes, with hydrogen large scale storage driven by the growing availability of cheap excess renewable electricity and the need of the transport sector to establish a hydrogen infrastructure across Europe. HyUnder comprises two parts, a general part (geology for and potential of hydrogen underground storage, below- and aboveground technology, general European energy framework and benchmarking against competing storage technologies) and a country specific part. This part comprises joint results comparison of individual case studies on hydrogen underground storage for France, Germany, Romania, Spain, The Netherlands and the United Kingdom will be presented. Each case study has considered for the assessment the competitiveness of hydrogen storage against other large scale energy storage concepts, the geological potential for hydrogen storage in the region, and how to embed the hydrogen energy storage in the energy market. Results have shown the interest of the technology in short - medium term especially linked to certain conditions of high intermittent renewable energy penetration in the European power grid that results in surplus or residual electricity.
