6 June 2018 Libertine FPE - Investor intro
• 40kWe Free Piston Engine will
generate power with ~45-50% fuel to
electrical efficiency
• Replaces incumbent technology
offering ~30-33% efficiency
• 40 kWe can be generated from the
same fuel input required for ~27 kWe
using existing generator sets
~1/3 more useful output
from the same fuel input
