Hydrogen fuel cells (HFCs) convert the hydrogen into electricity to power passenger vehicles, trucks and buses. Larger HFCs can deliver back-up power to a whole building, replacing diesel generators. The problem is that 99 per cent of all hydrogen fuel used in the world right now comes from coal and natural gas which are fossil fuels.

Methods to produce hydrogen without the use of fossil fuels involve the process of water splitting, or splitting the water molecule (H 2 O) into its components oxygen and hydrogen. When the source of energy for water splitting is renewable or low-carbon, the hydrogen produced is sometimes referred to as green hydrogen.
Electricity had a global average renewable share of about 33% in 2021, which means that only about 1% of global hydrogen output is produced with renewable energy. Electrolytic hydrogen from dedicated production remained limited to demonstration projects adding up to a total capacity 0.7 GW in 2021.
As the energy landscape evolves, green hydrogen could significantly disrupt the competitive balance between these two industries.
