DK energiø er et forsøg på fremtidig fossilfri elnet infrastruktur.
Men hvis man skifter til "det lange lys" i 2050 mangler visioner om brint infrastruktur.
Nedenstående link "Hydrogen. The Bridge between Africa and Europe" beskriver mulige energi infrastukturer mellem Europa og Afrika.
Verdens energibehov kan dækkes af et arealstørrelse på 8% af Sahara, da solcelle og vindkapacitet her kan være over 50%.
A European energy system based on 50% renewable electricity and 50% green hydrogen can be achieved by 2050. The green hydrogen shall consist of hydrogen produced in Europe, complemented by hydrogen imports, especially from North Africa
What needs to be done To be realized in 2050 (to cater for Europe’s energy demand)
Production Wind capacity 1,800 GW; 1,300 GW in Europe and 500 GW in North Africa
Electrolyser Capacity 3,400 GW; 700 GW in Europe and 2,700 GW in North Africa Infrastructure
Hydrogen pipelines 1,000 GW pipeline connection between Europe and North Africa. Re-use existing gas pipeline infrastructure in Europe and North Africa, conversion from natural gas to hydrogen Expand pipeline capacity, especially from south to north of Europe. Realize pipeline connections between North African countries from east to west.
Electricity grid Massive capacity expansion of the electricity grid, at least with a factor 2 on a volume base Grid re-enforcement and new grids are required between the renewable electricity production in Northern and Southern Europe and the load centers. Capacity expansion of interconnections between countries. Realize an electricity grid in and between North African countries
Storage Salt caverns 15,000 Salt caverns; 10,000 in Europe, 5,000 in North Africa Hydrogen storage in empty gas fields if possible Batteries are required, especially for day-night storage; North Africa could rely much more on battery storage than on hydrogen storage, due to its climatological conditions Heat storage Seasonal heat and cold storage for space heating, especially in aquifers and rock formations. This is important for North-Europe
