1 Kg of Kerosene releases 12.2 KWH.
1 kg of the best current battery can store ≈ 0.3 KWH.

I-EMD³ By-Pass Hybrid architetures offer the best compromise between parallel and series hybridization,whare average power and transient power are always developed at maximum system efficiency.
WHY GO HYBRID-ELECTRIC ?
Until batteries' specific power improves by at least a ten fold factor along with solid cycle life, hybrid-electric technologies are the only PRACTICAL solution capable of reconciling current and future mission profiles with low carbon footprint.
