Iron-air battery - will decentral summer/winter balancing become standard?
A new big duel is emerging: hydrogen fuel cells, power to methane and combined cycle power plants against the iron-air battery. Where can the iron-air battery save costs?
Previously, decentralized lithium batteries were assumed for day/night balancing and centralized large-scale technology such as power to methane, underground methane storage, and combined cycle power plants for summer/winter balancing. The prospect of iron-air batteries at 10% of the cost of lithium batteries changes this future forecast. The optimum for cost optimization could be 20% decentralized iron-air batteries and 80% centralized large-scale technology power-to-methane to combined cycle power plants, thereby eliminating the need for power grid expansion.

01:08 Stable energy supply through low-cost storage
01:22 Off-grid deployment in a GEMINI next generation home
01:41 Vienna 1000 kWh, Berlin 2000 kWh, Oslo 4000 kWh for winter
03:02 Iron-air battery drastically beats hydrogen fuel cell
04:59 Simulation with 2008 solar data: 900 TWh electricity demand 1400 GW PV
05:47 Data for underground gas storage and CCGT power plants
06:00 Deployment of CCGT power plants and power to gas are clearly separated in time
06:30 Methane storage would need to be supplemented by 245 TWh in the summer half-year.
07:34 The iron-air battery is only 40 TWh of electricity short
08:33 Where is the cost optimum decentralized iron-air - centralized power to CH4?

11:33 100 17 kW power connections on a 400 kVA transformer
13:06 4 MW of pure grid dumper photovoltaics requires 3 MW transformer
13:54 With 3 kWh LiFePo4 battery per kW of PV, only 1 MW transformer
14:42 Iron-air battery enables peak shaving to 0.4 MW transformer
16:47 Average daily yield is only 75% from 0.4 MW transformer
17:48 Target is planetary renovation, -250% CO2 until 350 ppm is regained
18:12 Carbon fiber replaces steel, iron-air battery as new task for iron industry
