About FeTu Limited

FeTu Limited is a research and development enterprise established in May 2016 in West Yorkshire, UK, focused on creating green energy solutions to reduce carbon emissions across various industries. The company was founded by Jonathan Fenton, a design and engineering manager who conceptualized the core technology as a teenager and developed a functional design in 2015. The idea was born from a childhood challenge by an elderly friend to one day create a more efficient engine. After years in a design engineering management career, a moment of inspiration in 2015 led him to solve a key aspect of the design that had previously eluded him. Fenton initially funded the project with help from friends and family before securing investment from angel investors, which allowed him to dedicate himself to the company full-time.

The company's core technology is the FeTu 'Roticulating' concept, a novel energy architecture that seamlessly converts between volumetric and rotational energy. This system is described as the world's first 'quad-acting' device, using only two moving parts to operate four anti-phased compression chambers, which enables a low-loss, efficient conversion of energy. The versatile 'continuous positive displacement' machine can function as a compressor, pump, turbine, or expander. This flexibility allows it to run any thermodynamic cycle, making it suitable for applications such as waste heat recovery, air conditioning, and power generation. One of its key features is the ability to recover low-grade waste heat from temperatures as low as 40 degrees Celsius and convert it into electricity. The technology is designed to be lightweight, scalable, robust, and cheaper to manufacture than traditional machines.

FeTu operates on a business model centered on its extensive intellectual property portfolio, which includes patents spanning over 40 territories. The company seeks to collaborate with or license its technology to end-users, industry organizations, and OEMs looking to improve energy efficiency. The initial target market was the oil-free, low-pressure compressor market, but the technology has applications in data centers, manufacturing, electric vehicle range extension, and renewable energy sectors like solar and geothermal. The company has received support from UK innovation agencies, including Innovate UK Business Connect (formerly KTN) and the Advanced Propulsion Centre (APC), which helped refine its business strategy and accelerate development. In October 2024, FeTu invested £1.5 million in a new manufacturing facility in Huddersfield to produce its components in-house in response to growing demand.
