WE HAVE DEVELOPED AN ENGINE THAT RUNS ON HOT WATER (c.90°C)
- Cost-effective – 3.5 year payback
- Green (no emissions)
- Easy (1-day install)
- Available 24/7
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. Exergyn aims to change this. Exergyn has noticed that so much energy is wasted as hot water and we aim to use it. Exergyn has a really innovative, easy-to-use solution to deliver cost effective electricity where and when it is needed AND with no emissions.
Until now there has been no commercially feasible way for hundreds of thousands of companies worldwide to make use of the enormous quantities of wasted hot water (c.90°C)(or low-grade waste heat “LGWH”) that they produce. This is about to change.
If your generators or processes produce wasted hot water, you can increase your profitability and decrease the carbon-intensity of your business with the Exergyn Drive™.
The Exergyn Drive™ converts LGWH to electricity.
We enable customers to:
-Utilise low-grade waste heat for the first time
-Increase revenue from power-generating plant
-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. The drive is based around a solid-state reciprocating technolog. Ths is thermally cycled to deliver rotary motion, and then converted to electricity. Characteristics include:
Why select the Exergyn Drive™?
LCOE potentially less than €0.05/kWh is very low for any generator. This is combined with low investment cost rapid payback.
Utilising energy which would otherwise be wasted, it produces electricity with zero emissions, CO2 or pollutants and it uses no refrigerants.
10kW modules can be linked together. We expect to increase the output of a generator by up to 9% with jacket heat and exhaust heat recovery.
It is a robust technology, we use a wire which expands and contracts, it really is that simple. Operates 24/7 with lifespan of 20 years.
Increase power output with no increase in emissions or fuel consumption, thereby improving overall plant efficiency and increasing profitability.
The system is designed to be retrofitted to a wide range of existing systems. It bolts on to process plants, biogas plants and microgrids with ease.
Installation in less than one day on a flat surface with two hot water flanges and one electrical hook up and a radiator if required.
The compact unit has minimal site impact with low vibration and low noise and no hazardous fluids to leak out.
The Exergyn Drives™ is fully bypassed, ensuring that there is no potential impact on the host engine in the case of shutdown.
The ‘fuel’ for our solid-state reciprocating engine is hot water – a resource that up until now has proved almost impossible to exploit commercially. And there’s a lot of this fuel about.
The amount of energy lost globally each year as wasted hot water is equivalent to twice the output of Saudi Arabia (oil & gas!)
Many heat recovery solutions exist. Organic Rankine Cycle (ORC) is one of the most successful and it is ideal when recovering waste heat at higher temperatures. At lower temperatures, both output and efficiency drop and this in turn increases CAPEX/kWe and lengthens the payback period.
Exergyn is fundamentally different. Our products are not sensitive to temperature in the same way. The CAPEX/kWe will be about ½ of ORC, so we have rapid payback.
The Exergyn Drive™ does NOT use refrigerant working fluids.
The Exergyn engine operates at the temperatures that many ORC have on the outlet. Exergyn Drive™ can therefore bolt on to ORCs to produce hybrid WHR (waste heat recovery).
If the Exergyn Drive™ was fully deployed in all its target market, then over 1.2% cut in global carbon emissions could be achieved. The Exergyn Drive™ also helps deliver cleaner air as there are no emissions of other greenhouse gases and pollutants such as NOx, SOx, change than is a reliance on the goodwill of companies to choose the ‘right’ path.
The potential market for our products is enormous. In the renewable energy sector, for example (incl. biogas, syngas, geothermal energy or solar energy), enhanced tariffs can significantly boost the returns to customers. Even without “green tariffs” many profitable markets exist for the Exergyn Drives™ e.g. shipping, gensets and industrial waste heat. The Exergyn Drive™ can also store energy and provide solutions for energy storage applications, potentially offering a cleaner, lower cost alternative to current storage solutions.
