Giving biogas a good scrub
We are currently investigating biogas generation for energy production, using anaerobic ponds at Ruakura. In one recent experiment, with the University of Auckland, we tested ways to 'scrub' the gas.
The biogas produced in the anaerobic digestion phase of sewage treatment contains 50-70% methane.

The parched earth on the cover says it all: droughts can be devastating. As can floods, and other extreme weather. A new book suggests ways that agriculture and forestry practices around the world could be improved to cope better with natural climate variability.

Analysing maps of extreme minimum temperatures allows Shell NZ Ltd to estimate the risk of fuel freezing, and hence helps them to set specification limits for different fuels being stored around the country.
NIWA was recently asked to produce several maps showing the nationwide patterns of minimum temperatures for the winter and spring months. One of the maps, the 10th percentile extreme minimum air temperature for the month of July, is shown here.
