The Minister of Energy Hon Gerry Brownlee will open the largest wastewater algae to bio-crude oil demonstration project in the world this week.
The project combines NIWA’s scientific expertise on advanced wastewater treatment and algal production pond technology with Solray’s bio-crude oil conversion technology and is hosted by Christchurch City Council at the Christchurch Wastewater Treatment Plant.
The aim of the project is for NIWA to produce between 150 and 300 tonnes of algae per year from the 5 hectares of wastewater treatment High Rate Algal Ponds. After harvesting and dewatering, this algae could potentially be converted into 45,000 – 90,000 litres (275 – 550 barrels) of bio-crude oil by Solray.
This bio-crude oil would normally be converted into a variety of products such as LPG, petrol, kerosene, diesel and bitumen, but if this amount were completely converted to petrol, it would power between 22 and 45 cars per year.
