Vallourec’s Delphy vertical hydrogen storage solution receives technical qualification from DNV

Vallourec, a world leader in premium seamless tubular solutions, announces the official qualification of Delphy, its vertical gaseous hydrogen storage solution, by DNV. A world first, Delphy enables the storage of 1 to 100 tons of hydrogen under maximum safety conditions. Thanks to its minimal footprint, this vertical system - extending up to 100 meters underground - meets the challenge of complex and demanding industrial environments. It targets both green hydrogen producers and industrial players such as synthetic fuel producers (e-SAF, e-methanol), green ammonia producers, steelmakers, and refineries.

DNV embarks on groundbreaking hydrogen blending feasibility study to decarbonize gas system in British Columbia

DNV is executing hydrogen blending feasibility studies for Enbridge, Inc. (Enbridge) and FortisBC Energy Inc. (FortisBC). The two individual studies will determine the percentage of hydrogen that can be safely transported through existing natural gas pipeline infrastructure, including Enbridge’s transmission system and FortisBC’s distribution system, both located in British Columbia, Canada. These studies, which are the largest blending studies undertaken in North America, will be used to develop the codes and standards required to safely transport hydrogen as the first step in forming a sustainable commercial hydrogen market.
