Renewable energy

Over 80 percent of the electricity generated in Aotearoa NZ comes from renewable sources – wind, sun and water. Understanding the effects of our changing climate on our hydro lakes and wind and solar generation potential will help us increase renewable energy generation.

  • Bio-oil from wastewater algae

    Research Project
    This project will demonstrate the commercial feasibility of producing bio-oil by the conversion of algae biomass that has been grown in wastewater treatment facilities. In particular we aim to maximise algae production in High Rate Algal Ponds (HRAP) by adding carbon dioxide, and demonstrate energy efficient conversion of algal biomass to bio-oil.
