Its G3-UHt unit used a feedstock of tyre crumb as part of the extended trial at the Energy Centre of Thornton Science Park in Cheshire.
The synthesis gas (syngas for short) produced contained 50% hydrogen, which it wants to turn into a vehicle fuel.
The other constituents were carbon monoxide and methane.
“PowerHouse has long focused on the efficient generation of energy from waste. However, our ability to generate a concentrated volume of hydrogen from waste, on a distributed basis, sets us apart from others,” said chairman Keith Allaun.
“We believe that distributed modular gasification is critical to opening the door to the coming hydrogen economy.
“These trials will allow us to manage and maximise the constituent elements of the syngas we create to best serve our business model objectives of delivering hydrogen as a road-fuel.”
