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.

A New Engine for a Cleaner World

Kaigia’s Green Fuel Motor (GFM) combines modular architecture and variable piston trajectory to achieve optimal combustion for renewable fuels. Slow, complete combustion is made possible for fuels like ammonia and biofuels, while hydrogen is handled with a fast, efficient cycle.

One Green Fuel Motor powering every mode of transport.

With sustainable fuel.

New Hybrids

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 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.

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 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 New Mobility 🤖🚙
N100 series

Go lighter, cleaner, farther. Kaigia New Mobility delivers compact, lightweight, and emissions-free propulsion for emerging transport concepts. From urban pods to next-generation micro-mobility, it provides high efficiency in a small footprint — enabling sustainable vehicles designed for agility, autonomy, and new horizons in clean transport.
