Modular Clean Propulsion Platforms

One core technology, multiple applications.

Kaigia develops a new generation of zero-emission thermal engines optimized for green fuels. Designed as modular platforms, our solutions scale from handheld tools to light aviation — empowering industries to decarbonize without compromise.

Kaigia Drive 🛞
D100 series

Net-zero engines. No redesign required. Kaigia Drive is designed for next-generation passenger vehicles, as main engine, hybrid or range extender. With high efficiency, fuel flexibility, and compact integration, it enables manufacturers to reduce weight, cut emissions to zero or net-zero depending on the fuel, and extend range without sacrificing performance or refueling speed.

Kaigia Haul 🚛 H100 series

Heavy loads? No sweat. Kaigia Haul targets freight and public transport fleets that need torque, uptime, and decarbonization. Built to operate on biomethane or ammonia, it delivers long-haul capability with minimal infrastructure change, accelerating sustainability in the most demanding segments.

Kaigia Aero✈️
A100 series

Fly farther, faster, cleaner. Kaigia Aero is a compact on-board charging module for hybrid that scales from utility drones to people transporting drones and light aircraft. It triples flight endurance compared to battery-only solutions while remaining quiet, low-vibration, and compatible with Hydrogen or Ammonia/Hydrogen mixture — opening new possibilities in aerial logistics and mobility.

Kaigia Marine 🚤 M100 series

Clean power across every wave. Kaigia Marine is built for ships, ferries, and private craft seeking sustainable propulsion. Optimized for ammonia and biomethane, it combines long-range capability with exceptional efficiency, balancing power, refueling flexibility, and environmental responsibility.

Kaigia Power 🔌 P100 series

Kaigia Power provides scalable, efficient stationary energy for off-grid, backup, or hybrid systems. With multi-fuel capability and modular deployment, it bridges clean generation from small installations to industrial-scale operations.

Kaigia Tools 🛠️
T100 series

All-day operation, net-zero emissions. Kaigia Tools brings clean propulsion to portable, high-autonomy applications — from generators to professional tools and motorcycles. Lightweight and fuel-flexible, it reduces emissions and extends operation times without adding bulk or complexity.

Kaigia Robotics 🤖
R100 series

Not quite robots for now — we start where impact is fastest. Robots? Go anywhere, do anything. Kaigia Robotics powers autonomous and remote-operable platforms — from inspection drones to robotic tools. Compact, fuel-flexible, and high-efficiency, it extends operational runtime while keeping net-zero emissions, enabling industries to deploy robots in remote or sensitive environments safely.
