Hydrogen as an energy store is not competitive but complementary to the electric economy, and both should be promoted together to achieve a faster transition towards a CO2 emission-free economy.
There is growing support to electrifying our economy by getting off of fossil fuels by producing renewable energy by wind and solar photovoltaic plants and using batteries to balance production and demand or to store energy onboard vehicles that cannot move along electric lines. Unfortunately, this proposal is pushed forward negating the value of hydrogen as an energy store. As here commented, the hydrogen economy is not competitive, but complementary and synergetic to the electric economy, and both should be promoted together to secure a faster transition towards a CO2 emission-free economy.
