Grid connection is one of the most relevant challenges for the development of biomethane projects. To transform the gas produced into truly usable energy, it is not enough to build the plant: it is essential to assess grid capacity in advance and choose the most suitable injection solution. With increasing electrification and declining gas demand, these aspects are becoming increasingly complex, especially during periods of low consumption. The experience of CNG Services shows how selecting the right connection strategy, particularly access to the high-pressure transmission grid, can provide greater flexibility today and support future developments, including the production of e-biomethane from renewable hydrogen and captured CO₂. A concrete example of how long-term planning is essential to building a more resilient energy system.
