...%, with a 10% step. The inclusion of H 2 substantially increased the pressure profile at both the TGP's mainline and delivery nodes (sinks). This rise in pressure resulted from notable reductions in both density and viscosity as the H 2 fraction increased, contributing to decreased hydrostatic...
