ABB High Power Rectifiers for Hydrogen Production

High Power Rectifiers for Hydrogen Production

The best solution for efficient and reliable DC power supply

for large scale industrial water electrolysis

Scaling up H₂ capacity to power the future by

leveraging ABB’s comprehensive experience

Hydrogen is a key fuel for tomorrow’s economy

Hydrogen electrolysis can serve as a sustainable bridge in

the gap between electricity and chemical energy carriers,

thus allowing fossil free powering where direct electrifica

tion is not feasible. This means hydrogen can play a crucial

role in achieving government and corporate sustainability

targets, with ABB supporting these aims by providing

best-in-class electrification technology for the hydrogen

economy of tomorrow.

Annual demand up to hundreds of millions of tons of H₂

Ammonia:  Direct use for fertilizer production

Synfuels:  Replacement in combustion engines

Industry:  Chemical, steel, cement and others

Buildings: Private and commercial heating

Transport:  Fuel for cars, rail aviation & ships

Power:  Energy storage for reconversion

Refining: High quality fuels and feedstock

Replacing fossil-based production

Hydrogen today is mainly produced by natural gas reforming

or coal gasification¹. Carbon capture may provide an interim

solution to prevent the release of CO₂ to the environment.

But only electrolytic production of H₂ allows to eventually

eliminate fossil fuels from the energy value chain – and

thereby full control of carbon emission and a steady

pathway to a sustainable future.

Electrolysis will move up to scale

The hydrogen council states that the annual demand for

hydrogen could increase tenfold by 2050. This will require

centralized gigawatt industrial production facilities that

leverage economies of scale. Hundreds of megawatts or

gigawatts of power per plant pose different challenges com

pared to existing installations. With our wealth of experi

ence in industrial electrolysis, ABB is the perfect partner to

expand the boundaries of H₂ production.

Decades of experience in chemical production

ABB has supplied more than 750 rectifier projects for

chemical plants since 1958 – a successful track record

for our clients to benefit from as they scale up their

H₂ production.
