All objective and scientific analyses of sustainable energy conversion that have been accomplished in various jurisdictions all around the world have determined, with certainty, that a sustainable future requires hydrogen and its derivatives. It is inevitable that our posterity will not depend upon fossil fuels to support their quality of life, freedom, mobility, and health.  Limited fossil resources and the harmful effects of burning fossil fuels to both the environment and human health will eventually force humanity to choose an alternative.  Many countries and states that understand and realize these facts have significantly decarbonized and depolluted their electric grids and have policies for completely decarbonizing and depolluting electric grids by date-certain (e.g., 2045 in California).  The technologies used to accomplish this feat include solar, wind, nuclear, geothermal, wave, battery energy storage and other technologies.  As a result, it is important that end-users increasingly connect to the electric grid and attempt to use this clean electricity when it is produced, or include energy storage to match supply with demand.  In addition, certain electric technologies like heat pumps and batteries are much more efficient than their fueled alternatives so that their adoption should become widespread throughout society.  Shifting as much of societal energy demands to the electric grid is the most important strategy for decarbonization and depollution throughout the world.  But, since we only deliver about 20% of primary energy by electricity today it is impossible to expect that the remainder will be able to convert to electric operation.  In addition, some of the 80% of energy demands require features, such as light weight, reducing gas, high temperature heat, the hydrogen chemical, long duration and/or massive storage, etc. that cannot be delivered or that cannot be easily or cost-effectively delivered by electricity directly.  As a result, we must electrify everything that we can possibly electrify and then we must invest heavily in hydrogen and its derivatives to get the rest of society decarbonized and depoluted.  Most of the hydrogen will be produced by electrolysis of water with zero emissions electricity, essentially becoming the new electrification vector that delivers clean energy through “new” transmission and distribution systems (pipes) to new end uses (those that require hydrogen features) that comprise the only known strategy and set of technologies that could enable decarbonization and depollution of everything for everyone.
