Researchers at ETH Zurich have developed a new technology for the seasonal storage of hydrogen that is considered much safer and cheaper than existing solutions. This method involves a reaction between hydrogen and iron oxide, resulting in iron that is easy to store and can later be converted back into hydrogen and iron oxide.

On 26 August, Uniper held an opening ceremony for the Hydrogen Pilot Cavern (HPC) demonstration plant in Krummhörn, Germany. The pilot cavern will be used to investigate and test the full potential of a salt cavern specially built for the storage of green hydrogen under operational conditions.

Tata Steel and Welspun Corp have developed hydrogen-compliant API X65 grade pipes, which successfully surpassed all necessary critical sour service and fracture qualification tests for the transportation of 100% pure gaseous hydrogen under high pressure (100 bar) at RINA, Italy.

Norwegian floating LNG infrastructure provider Höegh LNG has signed an agreement with Deutsche ReGas, a mid-sized company in the European energy infrastructure sector and operator of privately financed LNG terminals in Germany, to realize a floating hydrogen import terminal in Lubmin.

Lhyfe recently delivered 350 kg of green hydrogen to Géométhane, a subsidiary of the ENGIE Group, for testing hydrogen injection into salt caverns at its Manosque site in southern France. Currently, Géométhane stores natural gas in these caverns. This experiment aims to study the behaviour of hydrogen when stored in the salt caverns.

North Carolina-based OneH2 has launched new cylinder technology for 931-bar high-pressure hydrogen tube trailers. The cylinder technology, a culmination of several years of development and investment, operates under a special permit issued by the U.S. Department of Transport for use on roads.

Global Energy Storage (GES) and Provaris Energy have entered into a collaboration agreement to develop a gaseous hydrogen import facility at the GES terminal in Rotterdam, capable of importing both refrigerated ammonia and compressed hydrogen, with redeliveries into barges, rail, truck and the hydrogen grid (HyNetwork) operated by Gasunie.

Vallourec and NextChem Tech, NextChem’s subsidiary dedicated to decarbonization technologies, have signed a partnership agreement aimed at integrating Delphy hydrogen storage solution, developed by Vallourec, into hydrogen and green ammonia production projects where NextChem is involved as technology provider worldwide.
