Everything you should know about hydrogen and our technology

Hydrogen is the most abundant element in the universe. It has a high energy density and can efficiently store energy over extended periodsn of time with limited energy loss. That makes hydrogen a highly effective and versatile energy carrier. Energy carrier for the future

Different types of hydrogen

Grey hydrogen

Produced using fossil fuels such as natural gas, oil and coal which emit CO2 into the air as the fossil fuels combust

Green hydrogen

Emission free hydrogen produced from electrolysis using water and electricity from renewable energy sources

Blue Hydrogen

Produced just like grey hydrogen with the addition of carbon capture and storage (CCS) – resulting in up to 90-95% less CO2 emission

How do we produce green hydrogen?

Hydrogen can be produced through the electrolysis of water, leaving nothing but oxygen as a byproduct. Electrolysis employs an electric current to split water into hydrogen and oxygen in an electrolyzer. If the electricity is produced by renewable power, such as solar or wind, the resulting pollutant-free hydrogen is called green hydrogen.

Why do we need green hydrogen?

Direct electrification of much of our energy system with power from solar, wind and other renewables is the first line of defense against the treat from climate change to the modern life as we know it today. But not all of our energy systems can be directly electrified. In particular industry, transportation and buildings – sectors accounting for approx. 65%¹ of yearly greenhouse gas emission in Europe – are difficult to decarbonise. Green hydrogen can play a vital role where direct electrification cannot be achieved. Below just a few examples of the applications:

 

Is green hydrogen price competivie?

As electricity comprises the largest share of the cost of green hydrogen, the price development of renewable energy is important to achieve cost parity with fossil fuel alternatives. Since 2010, the cost of solar and wind power has seen an 80% decrease, meaning that renewable energy is now cheaper than fossil fuel alternatives. At an industry-level and in a Danish setting, the cost for green hydrogen is estimated to decline by approx. 50% towards 2040, mainly driven by lower electricity costs, lower tariffs and lower capital expenditure, mainly related to the electrolysers. This combined with an expected regulatory push to increase CO2 taxes will be key elements in making green hydrogen a cost optimal option for end-users
