For biofuels to be both commercially and environmentally sustainable there are three criteria that must be met. First, the biofuels must be energy positive where the energy produced from combustion of the biofuel
must be greater than the energy used to produce it. Secondly, the use of the biofuel from creation to disposal (life-cycle) must have a smaller carbon footprint than a fossil crude oil derived equivalent fuel. And, thirdly the cost of the biofuel
to the consumer must be on par with or less than a fossil crude oil
Green crude is a hydrocarbon-based oil that can be used in oil-fired power plants or readily refined into transport fuels.
Unrefined green crude is in demand at oil-fired plants in remote locations or plants that provide peaking power at renewable energy installations including wind and solar.
Renewable liquid transport fuels are in demand from organisations and consumers concerned about fuel security, the environment, and or the volatility of future fossil crude prices.
Green2BlackTM is commercially scalable, ready to serve the growing demand in Australia and globally for renewable “drop-in” transportation fuels which are compatible with existing fuel infrastructure.
A recent Life Cycle Assessment on the Green2BlackTM technology undertaken by the University of Queensland demonstrated that, for production of ‘green’ diesel from marine microalgae feedstock, the Energy Returned over Energy Invested (ERoEI) ratio is 20% higher and GHG footprint is 30% lower than the conventional fossil diesel reference pathway.
The green crude produced from both marine microalgae and renewable biosolids are energy positive and have reduced carbon footprints compared with equivalent fossil derived crude.
