A novel pathway for producing sustainable aviation fuel (SAF) from renewable natural gas (RNG) is emerging as a technically sound solution for decarbonizing air travel. But its complexity on the economic and political fronts could make it difficult to commercialize. Since SAF plays a key role in meeting aviation's net-zero targets, industry leaders and analysts are scrutinizing whether RNG-to-SAF can deliver scale, viability and climate integrity. That conversation took center stage last week at the RNG and SAF Capital Markets Summit in Houston, where developers, financiers and analysts convened to debate the potential and pitfalls of this emerging supply chain.
