The Hydrogen Consensus

Let’s say there is such a thing as the “hydrogen consensus.” Most fundamentally, the consensus holds that hydrogen will be at the center of the sustainable energy economy of the future. By definition, hydrogen from fossil fuels will be off the table. Hydrogen from biomass will be on the table but the amount that can be derived sustainably will be limited by finite resources like land and water. This will leave a yawning gap (in the U.S., 60-70% of total energy consumption) that will be filled with the major renewables -- wind, solar, and geothermal -- and nuclear energy.

This may be as far as the consensus goes today, but more detail is now emerging on the global system of production and use that could animate a hydrogen economy.

IEA calls for renewable hydrogen and carbon-free ammonia

This week, an important new voice joined the chorus of support for renewable ammonia and its potential use as an energy vector - the International Energy Agency (IEA).

In his article, Producing industrial hydrogen from renewable energy, Cédric Philibert, Senior Energy Analyst at the IEA, identifies a major problem with the hydrogen economy: hydrogen is currently made from fossil fuels. But his argument for producing hydrogen from renewable energy leads almost inevitably to ammonia: "In some not-too-distant future, ammonia could be used on its own as a carbon-free fuel or as an energy carrier to store and transport energy conveniently."
