Cleanergy announces first deployment at a wastewater treatment plant
Cleanergy, an energy solution provider headquartered in Sweden, has installed one of its combined heat and power (CHP) systems at a wastewater treatment plant in Slovenia.
The system, which comprises Cleanergy's GasBox – the centrepiece of its CHP technology – has been deployed at the Jesenice plant in the north west of the country and is now generating heat and electricity from dirty methane gas being emitted at the site. The plant treats wastewater produced by approximately 25,000 people. Around 110,000m3 of dirty methane is produced every year at the site.
The CHP plat is producing around 100,000kWh of electricity and 400,000kWh of heat annually, which is being used for lighting, heating and powering equipment on-site. The GasBox works with methane of varying quality containing multiple contaminants and has been designed to cope with variations in the supply of methane.
Anders Koritz, Cleanergy CEO, says: 'The traditional systems for treating biogas are far too expensive for smaller wastewater treatment plants. Our GasBox was developed to provide a cost-effective option with a short return on investment.'
With a return on investment of between three and five years, Cleanergy's GasBox is already commercially deployed at several landfills in Norway, Poland, Slovenia, Sweden and the UK. 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 and a heat and electricity connection to a house/factory/warehouse with optional grid functionality.
