A modified Alpi Aviation Pioneer 300 ultralight is expected to fly in June using only batteries. In December it will fly with just fuel cell-derived power.

Called Skyspark, the all-electric prototype is designed to demonstrate take-off and cruise flight using only fuel cell power. The June battery-powered flight is to test the aircraft's all-electric systems as a safety precaution before the fuel cell is used.

A Turin-based company built Skyspark's dedicated electric motor. Liquid-cooled, it can deliver peak power of 75kW, but normally produces 60kW. Its fuel cell, developed by Turin Polytechnic, has a stack of three 20kW cells. Skyspark's designers plan for it to have a 135kt (250km/h) cruise speed and a top speed of 172kt.
