In a whitepaper released this week, Siemens Energy, along with pipeline operators Nowega and Gascade, have set out a step-by-step guide to converting the existing natural gas network into a “Pillar of a hydrogen-based energy transition.” Agnostic to how the hydrogen is produced in a technical sense, the report emphasizes the huge savings in carbon emissions that building out a hydrogen infrastructure along with renewable power would bring, and that one of the most cost-effective ways of doing so is to reuse natural gas infrastructure with only minor modifications for the transportation…
