I could describe the energy infrastructure of 15th century Holland by describing colorful windmills set up to drain swamps, saw wood, power woodworking mills, and process food. Dutch carpenters busily constructing a fleet of ships from cut lumber emerging in water troughs while logs are hauled into the mill by oxen, mules, or cattle.
I want to do something similar in my world. I am driving through my landscape in my wonderful ecologically-friendly hydrogen-powered economy and I want to describe the countryside, and seaside with elements of the power production infrastructure. Based on the answer to this question about hardening the complex energy infrastructure against hostile attacks, what does the distributed and redundant energy production with reserves look like as we drive down the highway? Because we have redundancy and are not producing at 100% capacity, maybe there actually are windmills creating pressure for steam reformation instead of wind turbines? Maybe Hydrogen is being pumped to homes blended with natural gas?
I choose to put the facilities near the highway because logistically and culturally we tend to put power production within easy access to roads and/or rivers (for raw material delivery), and away from residential areas. This has not changed in this story.
Part of the trip will be over coastal water (where tidal energy might be being harvested and packaged), and part through the countryside (where other methods will be used).
I'm looking for a description of the types of small(ish), distributed energy production facilities I drive by as well as the power distribution, storage facilities, etc. in this society which is hardened against single-point energy disruption. Consumer hydrogen is being made, distributed, (and maybe stored) while raw materials are being processed to make it. Nothing is blowing smoke, and no fossil fuels are to be found (except clean abiogenic natural gas) which in some part forms the carbonless Hydrogen economy infrastructure. Maybe greenhouses line the facilities where CO$_2$ from this process is helping crops?
I think the key difference from what we would see today is, no large centralized power plants, refineries, or solar farms - single points of failure. Facilities are not mega-million dollar engineering marvels, but an integrated net of simpler ways to convert whatever into a consumable Hydrogen product (maybe an LH2 tank or fuel cell?). Nothing we see is a "critical" component of the energy matrix - everything is replaceable or even modular, and we are tapping many energy sources to produce a standard consumable energy product. Also missing are gas tankers along the highway - but maybe they're carrying something else?.
After war-hardening the system against any threat with low-cost and replaceable components, What does a distributed and redundant Hydrogen infrastructure look like to a casual highway traveler? - the most likely scenario given we've accomplished this.
I'm hoping for two elements in the answer:
The society is consuming hydrogen for well over 90% of it's energy use, in any form (fuel cells, cryogenic, mixed gas, or whatever)
A good terrorist with only a few smuggled EMP or kinetic weapons would have no idea how to stop a city or even a large town from going about their daily energy routine.
