•
Globally, the aviation industry relies on sustainable fuels as an alternative to conventional fuels in its climate mitigation strategies. Adoption of electric aircraft still faces
technical obstacles, particularly related to the energy density of the batteries. The reduced air density at high altitudes further exacerbates this constraint for battery-
powered propeller. Thus, most of the global development of electric aircraft is focused on small aircraft such as VTOL and general aviation.
• Although the current generation of certified electric aircraft relies on batteries with an energy density of 144 Wh/kg, research into advanced battery technologies such
as NCM 811, LSB, and solid-state batteries holds a promise to significantly increase the energy density to 500 Wh/kg. This could greatly enhance the cruise range of the
electric aircraft.
• Despite the challenges, electric aircrafts have a potential market in Indonesia, particularly in the form of VTOL aircraft for areas with limited take-off and landing
infrastructure. Aircraft manufacturers around the world are developing electric aircraft designs, especially in the VTOL segment, and these aircrafts are expected to
enter the commercial market in the next few years.
