Would Germany be possible with 100% solar electricity?
The expansion of wind energy is faltering. Is wind energy really indispensable for the energy transition or would it even work with exclusively 100% solar power?
How would 1400 GW of photovoltaics cope with 900 TWh of net electricity consumption in Germany?
00:37 Wind Energy Inventory and Expansion in Germany
01:11 Solar power alone? Question only made possible by new building standard
01:41 Distribution of world population by latitude
01:53 What is there on other continents at the latitudes of Germany?
02:58 Scenario 1400 GW photovoltaics 4000 GWh batteries 900 TWh consumption and power to gas
06:10 December 2020 lithium iron phosphate batteries for under 100 € / kWh total cost
07:12 Structure of the calculation
08:41 80 GW CCGT power plants are enough, very few load changes
09:45 Extreme load changes every day in current system
11:00 Other design criteria for CCGT power plants - rapid load change becomes unnecessary
11:53 180 GW power to methane is enough
13:27 Clear time separation between CCGT and power to methane deployment
14:37 A very sunny May week - 180 GW of Power to Methane all week
16:27 Evaluation of the result - 245 TWh of methane import needed
18:16 Level of underground methane storage
19:16 Surplus of southern countries for methane import needed
20:11 Expansion needs for underground gas storage
20:35 Hydrogen H2 unsuitable for power industry
