Carbon-Neutral Synthetic Gasoline: Technology, Cost, and the Investment Case
The chemistry has worked since the 1920s. The energy efficiency is 9 to 16%. The cost is 5 to 8x fossil. Airlines, defense, and Porsche are buying it.
Batteries
Solid-State Lithium Batteries in 2026: Are QuantumScape, Solid Power, and Factorial Worth the Investment Risk?
LFP cells cost USD 36/kWh in China. Nissan needs USD 65/kWh to break even on solid-state. That gap is the investment thesis, compressed to one number.
