Frontiers in Energy Research · 2023

Key Findings

01Levelized methane cost ranges from 4.5 to 8.5 €/kg, influenced by location, plant size, and concentrated solar power contribution.
02Methanol and gasoline production costs are lower due to larger mass production: 1.5–2.2 €/kg for methanol and 4–6 €/kg for gasoline.
03Increased direct solar radiation (100 kWh/m2) can decrease methane production cost by 2.4 €/kg.
04Small-scale systems are significantly more expensive than larger ones.
