Producing hydrogen by means other than electrolysis means extracting hydrogen without the use of electricity. Electrolysis of Water By providing energy from a battery, water (H 2 O) can be dissociated into the diatomic molecules of hydrogen (H 2) and oxygen (O 2). UV-light is enough to light it up. Bezdek, 2019. The challenges for widespread use of water electrolysis are to reduce energy consumption, cost and maintenance and to increase reliability, durability and safety. Using electrolysis as a method of hydrogen production demands high amounts of energy and is very inefficient. A small electrolyser can, therefore, be used with a hydrogen compressor to fill a vehicle or a quad. 11) per cub meter. Due to the rising share of electricity generated from renewable sources and the subsequent transformation of energy supply, hydrogen production has gradually assumed a much more prominent role. This year, a PM Breakthrough Award went to GE's.
