by Anmar Frangoul (CNBC) Hydrogen has a diverse range of applications and can be deployed in a range of sectors, including industry and transport. Green hydrogen is produced using renewable sources such as wind, solar and tidal power. — A project located on an archipelago north of mainland Scotland plans to combine tidal power and battery technology to generate “continuous green hydrogen.”
In an announcement Monday, the European Marine Energy Centre said it would deploy a 1.8 megawatt hour “flow battery” at a tidal energy test site located on the island of Eday, Orkney.
According to EMEC, the flow batteries, from Invinity Energy Systems, are able to offer “hours of continuous power, one or more times per day, through decades of service.”
What is green hydrogen?
Green hydrogen is produced using renewable sources such as wind, solar and in the case of the EMEC initiative, tidal power.
A flow battery, meanwhile, is an “easily rechargeable system that stores its electrolyte — the material that provides energy — as liquid in external tanks,” according to the U.S. Department of Energy’s ARPA-E (Advanced Research Projects Agency – Energy).
For the EMEC project, the flow batteries will “smooth” tidal production to create “on-demand electricity” which will be converted into hydrogen using a 670 kilowatt electrolyser.

Examples of its use in the latter include trains, airplanes, cars and buses powered using hydrogen fuel-cells.

Given this context, green hydrogen is growing in popularity, and over the last few years major firms including Repsol, Siemens Energy, Orsted and BP have got involved in projects connected to green hydrogen production. READ MORE
