Our mission is to significantly impact climate change and global air-quality for the better through the profitable, mass-deployment of our products

Exergyn is a creative clean-tech company, developing game-changing solutions to significantly impact global air-quality and climate change for the better.

Pioneers in shape memory alloy technology, Exergyn is leveraging its world-class expertise to develop product applications across many industries.

Exergyn’s innovative work will enable a reduction in carbon emissions and production of green, cost-effective, energy solutions worldwide.


We all use power at home and at work. We are all aware of climate change and we want clean energy that doesn’t harm the planet.  But we want power to turn the lights on when it is dark or cook at mealtimes – we can’t wait until it is sunny or windy. And we are all used to cheap energy. We want clean, low-cost power at the right time – but this is not an easy ask. This is sometimes known as the energy trilemma and it is one of the biggest headaches in the energy industry today.

We all want to have effective heating and/or air-conditioning in our homes, offices, factories, shops, schools, universities. We also want adequate supply of hot and cold water. Global economic development is driving an increasing demand for heating and cooling, alongside a need to reduce the use of fossil fuels and minimise the impact on the environment by reducing global carbon emissions. An alternative to fossil fuels are heat pumps. However, most heat pumps use refrigerants, which are harmful to the environment.

Exergyn is developing innovative, easy-to-use solutions to these problems, in the form of cost effective, clean-energy products.

Product Areas:

  • Domestic and Industrial Heating
  • Domestic and Industrial Cooling
  • Waste Heat Recovery
  • Energy Storage
  • Renewable Energy

Exergyn’s solutions will enable customers to:

  • Make use of low-grade waste heat 
  • Heat and cool buildings and water efficiently
  • Increase revenue from power-generating plants
  • Reduce energy bills
  • Reduce pollutant emissions for cleaner air
  • Reduce carbon emissions to tackle climate change
  • Maximise energy efficiency
  • Increase reliability of power supply
  • Enable delivery of environmental CSR objectives


The core of the technology is an elegantly simple device, based around a solid-state reciprocating technology.  This solid-state material, shape memory alloy “SMA” is at the heart of Exergyn’s innovation. It will deliver product solutions that:

  • Are efficient and cost-effective
  • Have NO emissions CO2, NOx or other any pollutants
  • Are simple and quick to install
  • Are flexible and scaleable
  • Are robust and low-maintenance.
  • Produce clean, reliable power
  • Are retrofittable
  • Emit low noise levels
