Generate electricity from dirty methane emitted from closed landfills



Elevator Pitch

Launched in June 2014, Cleanergy’s GasBox has been specifically developed to generate electricity and heat from methane gas being emitted at the hundreds of thousands of landfill sites which are more than 10 years old.

Previously the only option for treating methane emitted from closed landfill sites around the world has been to burn it at source as the resultant carbon dioxide warms the earth 20-30 times less than methane.

There are a myriad of Combined Heat and Power (CHP) systems available for generating electricity and heat from newer landfill sites. However, once the quality of the methane decreases below the levels required for traditional landfill gas engines, the only option that allows operators to comply with environmental regulations has been flaring.

Cleanergy’s GasBox addresses this specific problem and is an industry first.

Product

Installed inside a modular container, the GasBox is an autonomous and flexible stirling engine unit connected to 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.

Instead of using steam – created by fossil fuels – to make a vacuum beneath a piston, thus causing atmospheric pressure to drive the piston down, Stirling’s version uses the heating and cooling (and thus expansion and contraction) of a working gas sealed inside the engine to do the piston-driving.

Methane emitted from landfill sites is channeled into the GasBox where it is combusted in an external chamber. The external combustion generates heat which is transferred to the internal working gas. The working gas expands and moves the piston, after which it is cooled and then reused in the stirling cycle. In this process, the working gas fluctuates between 700 and 80 degrees centigrade. The expansion and contraction of the working gas moves the piston 25 times a second, and the motion is transferred to a crank shaft which is connected to a generator that produces electricity. Excess heat emitted from the external combustion chamber is also captured and used for heating water.



Why we are ecofriendly

Prior to the installation of the GasBoxes, all of the dirty methane gas emitted from closed landfill sites was flared and not generating any electricity and polluting the environment.

Thanks to the GasBoxes, this waste gas is not being used to generate heat and electricity.

Cleanergy’s GasBox is already commercially deployed in Norway, Poland, Slovenia, Sweden and the UK.
