SiriNor, a deep-tech aerospace startup from India and Norway, plans to conduct a qualifying UAV retrofit test flight in India by mid-to-late 2026, aiming to develop the world’s first emission-free electric jet engine. The engine, compatible with current battery technology and hydrogen fuel cells, utilizes a patented tip-driven propulsion architecture designed to lower manufacturing costs by at least 30%. Backed by investors like Shell E4 and Innovation Norway, SiriNor intends to commercialize UAV engines by mid-2026 and expand to regional aircraft platforms by 2030.
