Green Hydrogen To Boom

Why green hydrogen is the renewable energy source to watch in 2021; The price tag and energy needed to make it will be worth it, experts say

Green hydrogen, an alternative fuel generated with clean energy, is experiencing a global resurgence and has been identified as the clean energy source that could help bring the world to net-zero emissions in the coming decades…[It is expected to cost the same] as conventional hydrogen within a decade…Several countries around the world already invest heavily…[and the market] is expected to grow exponentially…Bloomberg NEF estimates that an $11 trillion investment in production and storage worldwide through 2050 and more electricity than the world generates now to have green hydrogen meet a quarter of the world's energy needs…

…[Green hydrogen] carries one quarter the amount of energy per unit compared to natural gas, can embrittle metal and is highly combustible, Liebreich wrote…[Current investment and production are] only expected to generate 3 million tons a year, compared to a global target of 8.7 million tons per year…[C]arbon-free "green" hydrogen is made using [zero-emissions wind and solar] electricity split the hydrogen molecules from oxygen molecules…[The byproduct is] water…

Green hydrogen is forecast to fill 15% to 20% of the world's energy needs that will not be easily met with battery, wind or solar power…[which cannot fully serve long term storage, heavy manufacturing, or] long-distance transport…[I]t will need to be pressurized and then moved, either through a pipeline, ship or truck using the existing infrastructure…The production of fossil fuels must be decreased by 6% per year between 2020 and 2030 in order to prevent a "catastrophic" global temperature rise…” click here for more
