SOLUTIONS

Driving a new
generation of
sustainable
energy

Proven, sustainable energy solutions
for the gas and solar industries

Our Combined Heat & Power (CHP) and Concentrated Solar Power (CSP) systems are established and proven to perform, from Inner Mongolia to the UK.

Their service life is some 200,000 hours (up to four times that of traditional solutions).

And they are equally effective both on and off grid.

Our CHP System is driven by our GasBox stirling engine and is today empowering landfill sites, farms and waste water treatment plants to generate more power – and profit – from low-grade methane gas.

Our CSP System is powered by our SunBox stirling engine that generates power from solar energy at grid parity levels – twice as efficiently as traditional Photovoltaic (PV) technology.

STIRLING CHP SYSTEMS

Turning waste into wealth

 

A turnkey CHP System…

In designing our Stirling CHP System we thought outside – and inside – the box.

The result is a turnkey solution that not only includes the GasBox, but is supported by a family of services from design, installation, piping and wiring to round-the-clock maintenance and troubleshooting.

Installed inside a modular container, the GasBox is an autonomous and flexible stirling engine unit. Also inside the container is a real-time power management system with remote access; a fuel pipe; plus a heat and electricity connection to a house/factory/warehouse with optional grid functionality. Power output is capped at 9kW per GasBox engine unit.

Stirling CHP System

Cleanergy Stirling CHP System™ in France

…that produces power from low calorific gas

18% tolerance

Extreme tolerance

The GasBox converts biogas with a low methane content (down to 18%) into electricity and heat.

This opens up new opportunities beyond traditional CHP systems: landfills can now produce power for 20 years longer – and raw biogas from both farms and waste water treatment plants can be used directly from source without processing.

LANDFILLS

CHP Systems for landfill sites

Is it time to consider ‘low cal’ for landfill?

The Cleanergy GasBox generates electricity and heat from low calorific biogas with a methane gas concentration as low as 18%. For landfill site owners it extends the ability to generate and sell energy by up to 20 years.

The result: a profitable new revenue stream with an estimated ROI of just three years.

It’s also more sustainable and puts an end to flaring – a practice which is coming under increasing scrutiny from the EU and other regulators.

In fact, today some 20% of all the world’s landfill gas is flared. So why let your profits go up in smoke?

If all the landfill sites in Europe used our Stirling CHP system for biogas extraction it would be enough to provide heat and power for 750,000 people – a city the size of Krakow, Stockholm or Amsterdam…

BIOGAS

CHP Systems for biogas sites

In the farming and agricultural industries, our Stirling CHP System turns raw biogas of any type and quality into heat and electricity.

The GasBox stirling engine is compatible with any type of biogas production installation no matter what type of organic substrates you use – from manure to food waste and plant residues.

And because the Cleanergy solution works with low cal methane, no upgrade of the gas is needed – which in turn means the raw biogas can be processed directly from the digester tank.

The amount of emissions produced by our Stirling-based technology is around 10 times lower than that of traditional internal combustion engines and generators (e.g. a standard gas genset).

TREATMENT PLANTS

CHP Systems for treatment plants

Our Stirling CHP System can even convert biogas at waste water treatment facilities into heat and power.

The system can run on biogas of any type and quality and is made for simple scaling – making it ideal for applications where the quality and supply of biogas varies over time.

STIRLING CSP SYSTEMS

Converting solar heat into electricity at grid-parity levels

A turnkey CSP System

In designing our Stirling CSP System we thought outside – and inside – the box.

The result is a turnkey solution that not only includes the SunBox but is also supported by a family of services from design and installation, to round-the-clock maintenance and troubleshooting.

Mounted on top of a parabolic dish that tracks the sun, the SunBox is an autonomous and flexible stirling engine unit. Cleanergy’s CSP System includes both the SunBox and the parabolic dish – plus a tracking system with remote access.

The system also includes a portable service unit and the potential for both interconnect and grid interconnect. Power output is capped at 11kW per SunBox engine unit.

MEGAWATT-SCALE
SOLAR PARKS

CSP Systems for solar parks

The Cleanergy SunBox is unique in its ability to generate power from solar energy at grid parity levels – twice as efficiently as traditional Photovoltaic (PV) technology.

Thanks to a unique tracking system that follows the sun throughout the day, SunBox has a higher yield than alternative technologies.

The result for solar parks? Electricity produced at €0.06/kWh – the lowest in the market (without the need for water to cool the system).

Furthermore, our solution meets the growing need for mega solar parks ranging from 10 megawatts to several hundred. Thanks to its modular design, our stirling dish technology reduces risk and complexity by effectively making every unit autonomous.

We believe it’s the best energy solution under the sun.
