Net zero refers to an ideal state where the amount of greenhouse-gas emissions released into the atmosphere is equal to the amount removed. To prevent a permanent—and catastrophic—warming of the planet, all industries must achieve net zero. Decarbonization, a reduction of carbon in the atmosphere.
Green hydrogen is hydrogen derived from water. It’s created using a process called electrolysis, wherein electricity from renewable sources is used to split the hydrogen molecules from the oxygen molecules in water. Because the electricity used here comes.
Industries that rely heavily on fossil fuels, such as heavy industries and long-haul transport, stand to benefit the most from hydrogen energy. The steel industry, which accounts for 8 percent of global annual emissions, represents a particular opportunity.
