One of the most interesting challenges to achieving carbon neutral electricity generation is harnessing the intermittent generation of solar and wind. Right now, many firms, households, and utilities rely on lithium ion batteries to store energy for times when generation is low. What if there were another solution for energy storage that produced carbon neutral electricity?
That solution might be hydrogen fuel. The benefits of hydrogen fuel for storing fuel are many. Hydrogen fuel can be generated by using existing hydrocarbon fuels, like excess methane from natural gas wells or landfills, or by using electrolysis to split water molecules. The fuel produced from these procedures burns extremely cleanly, producing essentially just water vapor and heat.
