Efficient technology

To meet the commitments in the Paris Agreement and limit global warming to 1.5 degrees, the Hydrogen Council estimates a global demand of 75 million metric tons (Mt) of clean hydrogen by 2030, rising to 660 Mt in 2050.

Realising the global ambitions for a net-zero society by 2050 depends on efficient and scalable solutions for green hydrogen production. Our contribution to the environment is determined by our ability to get products out on the market. This requires that we develop competitive technology and that we are able to scale production to meet the growing worldwide demand. Our technology is referred to as high-pressure alkaline system which delivers the hydrogen and oxygen gas with a pressure directly from the cell stack at 15 bar. The high-pressure alkaline technology is suitable for renewable energy input, and the electrolyser size we deliver is a perfect match for large-scale industrial applications such as power-to-gas, ammonia, and steel production.

Number one metric for electrolyser manufacturers is energy efficiency. It is measured by the electrolysers ability to produce hydrogen gas at a certain level of input energy. HydrogenPro’s single 5.5 megawatt electrolyser has been validated to produce 1,100 Nm3/h hydrogen at normal current density, which equals ~100 kg of pure and pressurised green hydrogen per hour. This means that the electrolyser is validated with 80% energy efficiency, setting a new global standard for large-scale production of green hydrogen.

In addition to optimising our existing high-pressure alkaline technology, we are on track to establish what we call 3rd generation electrodes. This is new electrode coating included in the existing high-pressure alkaline system based on novel research, which is currently being developed by HydrogenPro Denmark in Aarhus. Initial tests show that the 3rd generation technology can deliver an impressive energy efficiency of 93%, which is a 14% improvement from today’s technology.


Our greatest sustainability contribution is that our product is a key enabler for the global society to reach a decarbonised energy system. We contribute directly to reduced greenhouse gas emissions by offering technology to produce clean fuel that can replace fossil fuels in large parts of the energy economy.

In addition to the direct contribution to abatement of greenhouse gas emissions, green hydrogen plays a crucial role in allowing for a decentralised and resilient energy system that can be completely based on renewables. Hydrogen is offering a clean energy storage solution that can be used to buffer intermittent renewable energy sources and stabilise the grid both locally and regionally. Hydrogen is thus indirectly enabling this green shift, allowing for an energy system based on production of large-scale renewable energy from various sources. Renewable energy is the most critical component of a future net zero society and for the world to reach the Paris Agreement.
