One million ton of hydrogen is the key piece in the Danish renewable energy puzzle

Designing a 100 % renewable energy system (RES) for Denmark, the availability of a sustainable biomass resource potential is found to be a limiting factor. The biomass demand derives from specific needs in the system, i.e. 1) storable fuel for energy for balancing fluctuating power production, 2) carbon feedstock for materials and chemicals and 3) energy dense fuels for the more demanding branches of the transportation sector such as aviation, ship freight and long distance road transportation.
The challenge of balancing electricity over different timeslots comprise a short term balancing of supply and demand in every second, but also a long term balancing between days and even seasons. The needed scale of wind power production, and balancing, will largely be determined by the availability of residual biomass.
