A new EPRI report examines how hydrogen, ammonia, e-fuels, and carbon capture provide benefits beyond greenhouse gas reduction. These technologies can enhance energy security and grid resilience by reducing reliance on global hydrocarbon supply chains. By producing energy carriers locally from waste, biomass, or captured carbon, utilities can insulate their systems from geopolitical volatility. This shift moves fuel from a globally traded commodity to a locally controllable resource.

The report mentions these fuels can help manage the system, but I want to see the actual capacity factors. Using electrolyzers for grid balancing is great on paper, but the round trip efficiency is usually a nightmare. Do we have data on the actual cost per avoided curtailment?
That is why the incentive structure is key. If the tax credits only reward the carbon intensity and not the grid services, no one will optimize for resilience. We need a market design that pays for the flexibility, not just the molecule.
Local production of renewable diesel or RNG sounds good, but the feedstock logistics are usually the breaking point. Moving biomass or waste is expensive and labor intensive. I wonder if the report accounts for the actual cost of gathering these materials at scale.
Basically, EPRI is arguing that emerging fuels are a hedge against geopolitical chaos, not just a way to hit net zero. It is a more practical pitch for utilities that are scared of supply chain shocks.
