About us

Our mission is to bring forward the widespread use of Free Piston Engines in distributed power and transport markets.

In response to the challenges of climate change and energy security, cleaner sources of energy such as wind, solar, biomass and biofuels are being developed across the world. The diverse, distributed nature of these new energy supplies creates huge opportunities for improved small scale energy conversion technologies. Different design and manufacturing approaches are needed to make the best use of these new fuels and to reduce waste wherever energy is converted.

Libertine was established in 2009 to create linear machines for this new world. We have drawn on decades of experience in the automotive and motorsport industries, consumer product engineering and low cost manufacturing techniques. The result is a suite of ‘Linear Power System’ technologies for use in a wide range of power generation, heating, cooling and transport applications. Libertine’s technology will help make decentralised power generation the norm, bringing clean, reliable and affordable power to wherever it is needed, transforming the lives of millions of people.
