Standard Gas developed a commercial scale plant, fully permitted and licensed by the Environmental Agency, producing syngas used to generate electricity through a reciprocating engine from a wide range of carbon based waste feedstock.
The technology was assessed by the UK Environment Agency and achieved an End of Waste Certification on the gas, the only advanced thermal treatment technology to succeed in completing this rigorous assessment.
The process comprises essentially seven stages
- Feed delivery
- Primary pyrolysis
- Secondary gas cracking
- Gas scrubbing and cooling
- Carbon char collection and cooling
- Heat recovery
- Gas storage and/or compression
Reciprocating Engine at Huntingdon
Early sample gas analysis at Huntingdon
Flaring gas at Huntingdon during testing; exceptional pure smoke free flare
All the individual stages are technically mature. It is however an entirely innovative process, not the ‘creation of the new’ but the re-arrangement of the old in a new and different way, under the protection of six patents, which provide extensive IP security for the process.
9 week manufacture, rapid on-site assembly
Low comparative CAPEX cost
Low comparative OPEX cost
Small footprint (250 ㎡ ); location flexibility
High energy conversion efficiency and low parasitic energy load
High flexibility in waste types accepted
Conversion of low priced or negative value feedstock into valuable products such as synthetic gas, used to produce power, heat and potentially fuels, chemicals and molecular feedstock for new products
Diverting non-recyclable waste from landfill or incineration
Processes non-recyclable plastics
Replacing fossil fuel usage with reduction in CO2 emissions
Re-using redundant buildings
Reducing lorry miles – decentralised waste processing & energy production
Low environmental impact: Small footprint and zero emissions other than combustion of synthetic gas; no incineration
Our syngas has been certified 'End of Waste' by the Environment Agency in the UK - it is as clean as natural gas
The technology has converted a large number of different carbon based waste feedstock types. It can operate on blended waste streams from any of the categories below and more
- RDF – refuse derived fuels
- SRF – solid recycled fuels
- Mixed waste wood
- Auto shredded residue
- Oily sludge/oily rags
- Medical waste
- Tyre crumb
- High chlorinated plastics
- Non-recyclable paper & cardboard
- ABP – Animal By-Products
The technology is principally designed to produce a high quality clean synthetic gas or syngas. The composition of this gas is mainly methane, hydrogen and carbon monoxide, with a small percentage of other gases.
The gas can be used to produce: i) electricity through reciprocating engines; ii) conversion to “development” transport fuel under the UK government’s Renewable Transport Fuel Obligation (RTFO) which qualifies for substantial pricing incentives through at least 2032; iii) molecular feedstock for the chemical sector; or iv) or heat as required.
Once the waste feedstock has been converted there is a residue of ash-free char, richer in carbon that the original feedstock. This carbon char has a number of applications.
- Soil conditioner/enhancer
- Energy rich fuel
- Carbon black product/ (CBP)
- Activated carbon for use in air filters, sewage treatment, water purification
The high grade exhaust heat at 400c + can be used to raise steam to drive a secondary turbine to generate electricity in an integrate combined cycle.
This high grade heat can also be used in industrial/commercial processes. The lower grade heat can be utilized in a district heating system for residential or commercial heating requirements, such as space heating and water heating.
