About
The gas produced can be:
-
Used as a fuel elsewhere
-
Converted to other fuels such as hydrogen or used as a synthesis gas for the manufacture of chemicals
-
Used immediately for combustion on-site for combined heat and power production
Gasification is the conversion of a non-gaseous fuel, such as biomass, into a gaseous fuel.
Through funding from the Australian Renewable Energy Agency (ARENA) and as part of Renergi’s R&D phase, a 100 kg/hr demonstration plant has been designed, built and successfully tested. The Advanced Biomass Gasification Technology project demonstrated Renergi’s innovative biomass gasification technology that converts biomass, such as agricultural waste, into a clean gaseous fuel that can be used to generate electricity.
A key feature of this technology is the use of char as a catalyst (or char-supported catalyst) to catalytically reform tar into a clean gas. This eliminates the need to use a liquid (e.g. water or biodiesel) to scrub the gasification product gas. With this novel technology, we can achieve levels of tar content well below 100 mg per cubic metre.
Another important feature of this technology is its compact design, making it particularly suitable for combined heat and power (CHP) generation in distributed mode. It can accept a wide range of biomass as its feedstock.
By minimising volatile-char interactions, Renergi’s technology can achieve rapid gasification even at relatively low temperature and atmospheric pressure, greatly reducing the capital and operating costs.
Our technology also incorporates advanced energy recuperation principles to further increase the energy efficiency and can also use pyrolysis products (e.g bio-oil) as a feedstock.
Environmental Impact
Renergi recognises the urgent need to transition to clean and renewable sources of energy to fuel our industrial processes and economy. Renergi diligently champions the pursuit of further developing our technology to be even more sustainable and even less energy intensive.
