Energy - Research Projects

A combination of field surveys and on-site observations are being used along with laboratory-based experiments to determine the effects of seabed disturbance on benthic life.

NIWA, in collaboration with industry partners, has demonstrated that Covered Anaerobic Pond (CAP) systems for the collection and use of biogas from piggery waste can make good financial sense, and improve the environmental impact of livestock farming substantially.

NIWA worked with the community on the island of Totoya, in the Yasayasa Moala Island group in south-east Fiji to assess their energy security and energy related socio-economic opportunities.

Exploring opportunities for recovering biogas from farm effluent has produced a promising low-tech solution – covered anaerobic ponds. Not only is the technology an economical way of generating energy, it also has the dual benefit of providing farmers with a solution to their wastewater management issues while helping reduce their carbon footprint.

Understanding the complexity of tidal resources in New Zealand’s coastal waters and examining how extracting tidal energy would influence and be influenced by this variability.

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.

EnergyScape is a tool to help people understand and visualise the flow of energy in New Zealand.
