How are hydrogen and biogas included in the green transition of the Danish energy system?
In 2012 a new energy agreement was passed in Denmark. This agreement aims at the target of 100% renewable energy in the energy and transport sector by 2050. However, this target requires that we apply a sustainable energy system of renewable energy sources – and this includes the production and utilization of the so-called green gasses: hydrogen and biogas.
Green gasses can be utilized for heating, for industrial production and replace gasoline in the transport sector.
Surplus electricity from wind turbines can be utilized in the production of hydrogen through electrolysis. As mentioned above, hydrogen can be utilized in the transport sector and for industrial production.
Biogas can be utilized as CO2 neutral replacement of natural gas. By utilizing hydrogen, biogas can be upgraded to biomethane, which for example can be utilized as fuel in the transport sector and hereby replacing diesel and gasoline.
A large-scale production of hydrogen will require storage space. Salt Caverns are an excellent choice for storage of green gasses because they are very dense and impenetrable.
All three of the above elements form part in the activities we are working with in Hydrogen Valley.
