Cleanergy's GasBox makes wastewater treatment plant debut
The Jesenice wastewater treatment plant in north-west Slovenia is using Cleanergy's GasBox CHP system to generate electricity and heat from dirty methane gas being emitted at the site. It is the first time GasBox has been deployed at a wastewater treatment facility.
The plant treats wastewater produced by around 25,000 people, and creates 110,000m3 of dirty methane every year.
The GasBox, which forms the centrepiece of the complete CHP system, has been specifically developed to generate electricity and heat from the methane gas being emitted at smaller wastewater treatment plants such as Jesenice. It works with methane of varying quality containing multiple contaminants, and has been designed to cope with variations in the supply of methane.
Cleanergy’s CHP system at Jesenice is now generating around 100,000kWh of electricity and 400,000kWh of heat each year for lighting, heating and powering equipment onsite.
Nusa Jelenc, head of drainage and wastewater treatment at the Jesenice wastewater treatment plant, said: “Cleanergy’s CHP system is very impressive and exactly what the water treatment industry needs. Being able to reduce our methane emissions and generate our own electricity at the same time is fantastic."
Anders Koritz, CEO at Cleanergy, added: “The traditional systems for treating biogas are far too expensive for smaller wastewater treatment plants. Our GasBox was specifically developed to provide a cost-effective option with a short return on investment. We have filled a huge gap in the market and this is a highly promising market opportunity for Cleanergy.”
With a return on investment of as little as three to 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, Cleanergy’s 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.
