NWR information paper on the ‘hydrogen rainbow’

Developing a hydrogen market is an essential step in the transition to a climate-neutral economy. There are different views regarding the various possibilities available for producing hydrogen. These include questions relating to the environmental assessment of hydrogen, the quantities available, the associated costs, the opportunities and risks from an industrial and innovation policy perspective as well as the geostrategic implications. Against this backdrop, the NWR has presented a new policy paper designed to provide guidance and assistance to policymakers in making their decisions.

This document establishes a geographical relationship between the regions with high energy demand and the options available for hydrogen storage. It describes porous storage facilities and gas storages caverns along with their different geological formations, characteristics and the relevant advantages and disadvantages of each storage type. The need to expand existing storage facilities and develop new ones is evaluated based on the projected demand for hydrogen. The document also outlines how they are integrated into the grid infrastructure. After exploring the topics of security of supply, alternative storage options as well as costs, the document concludes with seven investigative reports which policymakers should draw on in adapting the legal framework for future hydrogen storage facilities. The NWR adopted the paper at its meeting on 29 October 2021.

NWR stakes position on the question of options and conditions for transporting hydrogen

Hydrogen transport plays a central role in the timely development of a market-based hydrogen economy in Germany. Interregional hydrogen transports connect producers and consumers and integrate the German hydrogen market into a European hydrogen grid. At its meeting on 2 July 2021, the German National Hydrogen Council (NWR) adopted a position paper on options and conditions for transporting hydrogen.
