Lithium power station factory in Denmark

Bulk physical storage of renewable energy produced gases can act as a longer-term storage solution (hours, days, weeks, months) to help maintain flexibility in a fossil-free energy grid (The Danish Partnership for Hydrogen and Fuel Cells). Without the hydrogen scenario, the potential for hydrogen-based energy storage in Denmark will be limited.

Danish Renewables is a sustainable energy company founded in 2017 by founder Esben Christensen in Copenhagen, Denmark, with a primary focus on the solar and wind energy sectors.

Unsurprisingly, Denmark is known as a pioneer of wind energy. Relying almost exclusively on imported oil for its energy needs in the 1970s, renewable energy has grown to make up over half of electricity generated in the country. Denmark is targeting 100 percent renewable electricity by 2035, and 100 percent renewable energy in all sectors by 2050.

As a leading independent hydrogen producer, Everfuel supplies hydrogen battery storage through trailers to bus and truck customers, fleet operators, and industrial sectors suitable for hauling hydrogen in trailers. The company offers Everfiller, a mobile hydrogen fuel solution for small to medium-sized heavy-duty fleets.

There are currently three EES facilities operating in Denmark, all of which are electro-chemical (batteries). A fourth EES facility – the HyBalance project – is currently under construction and will convert electricity produced by wind turbines to hydrogen through PEM electrolysis (proton exchange membrane).

Agora Energiewende and DTU Management Engineering, have postulated that this scenario report does in fact show that transitioning the Danish energy sector to 100 percent renewables by 2050 is technically feasible under multiple pathways.
