At the time of writing energy transition is in a state of flux, as such it is quite hard to get a true overall picture of the current global trends. It is affected by changing technology, practical application and complex geopolitical situations. However as of early 2023, Europe is leading the way in energy infrastructure transition toward renewable energy with the target of 20 million tons of clean hydrogen production, storage, and transportation by 2030, with approximately 50% produced with the EU [1]. One aspect of the European hydrogen plan uses carbon neutral energy sources to generate hydrogen, which is transported through both new and existing infrastructure, to be stored and consumed as a pure product or blended into existing natural gas lines. The expectation is that most hydrogen production is initially blended into the existing natural gas supply, with the addition of infrastructure for pure component, as production and demand increases. Other industrialized world areas are also eyeing the potential hydrogen provides.

There are new challenges that the pipeline and energy business need to overcome, and in this paper, we focus on the tools used to design and manage integrity, control room and commercial functions. In each of these traditionally siloed spaces, simulation solutions are employed that fulfill the engineering, operational and business requirements for existing natural gas pipeline infrastructure. As we navigate the global trend toward a more carbon neutral energy infrastructure, the techniques and tools noted require adaptation, including adjustments to the solutions used in pipeline simulators and how propagation of revisions potentially impacts other business areas.
