Exploring The Potential Of Green H2

Everything you need to know about hydrogen in the clean energy transition

Johnny Wood, November 29, 2022 (World Economic Forum)

“…[T]he growth of wind, solar and other renewables is vital for the global energy transition…[but] a base-load fuel is needed to generate power on demand to compensate when output from renewable sources is low or to boost supply during periods of peak electricity demand…[Clean hydrogen could also] help decarbonize hard-to-electrify heavy transport sectors like shipping, railways and buses…More than 100 pilot and demonstration projects are underway using hydrogen or its derivatives to fuel shipping…

Some heavy industries are also eager to embrace the decarbonizing potential of hydrogen…[A flurry of new ‘green steel’] projects have been announced that will use emissions-free hydrogen in the direct reduction of iron…[Grey Hydrogen produced by combusting natural gas] emits CO2 into the atmosphere…[Blue Low-carbon Hydrogen produced by combusting fossil fuels but with carbon capture, utilization and storage technology removes] most CO2 emissions from flue gases…

…[Green Emissions-free Hydrogen is] produced using an electrolyzer powered by renewable energy...In 2021, natural gas accounted for around 60% of total production with coal accounting for about 20%...[But by 2030 low-carbon hydrogen electrolyzer capacity] could reach 60 gigawatts annually by 2030…[and] the cost of electrolyzers could fall by 70%...[This would be] similar to the dramatic price falls that helped boost wind and solar power take-up…” click here for more
