The Refgas system uses downdraft gasification technology that is widely accepted as the cleanest and most efficient method of converting biomass and other feedstock into valuable synthesis gas (syngas), capable of directly fuelling standard engines to generate heat and power (CHP). Refgas’ innovative patented processes separate it from the competition, and this, added to 7 stages of syngas cleaning and cooling ensures that its product gas is ultra clean and of the highest quality possible. In fact, the syngas produced by our system has been proven and accredited to be cleaner than natural gas, making it one of the purest fuels available for generating power, and eliminating any concerns about its environmental impact.
Planning began in 2007 and 12 months later, the pilot plant had been built. In 2010, the system was upgraded to increase power output and make the system fully transportable. In 2014 the system was extended to incorporate fully automatic fuel storage and feeding, and given a control system upgrade facilitating almost total automation for a 24/7 generation. In 2015 the first commercial Refgas RG1000 units were ordered and Refgas went into production.
Typical syngas makeup:
Hydrogen – 12 to 17%
Carbon Monoxide – 17 to 21%
Methane – 2 to 4%
Carbon Dioxide – 12 to 17%
Nitrogen – 45 to 54%
Others – 1 to 2%
The syngas produced by Refgas is accredited as being cleaner than natural gas, making it one of the purest fuels available for generating power.
Refgas systems use gas engine generators to produce a combination of heat and power (CHP). The heat may be recovered as 90oC hot water, turned into steam, or even converted to chilled water. This means that Refgas can tailor the heat output perfectly, to suit its client’s needs for process use, space heating, refrigeration, drying or any other demand.
Refgas is now servicing orders for multiples of units across the UK, and fielding enquiries from every continent. Projects have been designed for outputs from 1MWe up to 12MWe, with hot water, steam or chilled water available alongside electricity production.
Refgas systems are constantly evolving, and with enhanced syngas cleaning and a further upgrade soon to be available to accommodate other waste derived fuels, such as those produced from municipal waste, they will soon be even more efficient. Refgas’ goal is to produce ultra-efficient systems which are as flexible and financially viable as possible
The main residue from the Refgas process is a valuable biochar, similar to granulated charcoal. With woody based fuels this amounts to approximately 5%, by weight, of the inputted feedstock.
Uses and markets for this biochar depend upon its quality, but it has potential to be used as a soil conditioner, a feedstock for activated carbon production or as a high-carbon fuel source in its own right.
The Refgas RG1000 produces 1MWe and 1.2MWt, enough power to service around 2,000 households, provide heat and power for an energy-hungry company or an island community, or to replace expensive alternative generation from, for example, diesel generators.
The Refgas design allows for multiple units to be co-located where outputs of up to 12MWe are required, and this provides for great flexibility in both operation and maintenance of the generating and CHP plant.
