Inside the wharenui at Pōhatuiri Marae discussing renewable energy and efficiency options.
Last year, the Pōhatuiri Marae Trust approached NIWA about renewable electricity solutions for their marae near Waitomo. "We asked ’electricity for what?’," says NIWA energy research engineer Rilke de Vos.
Biogas power made easy. It took less than two hours to convert an off-the-shelf generator to run on biogas at Dexcel’s Scott Farm, near Hamilton in the Waikato. Equipment with a total load of 9–10 kW ran happily for over two hours on electricity from the generator. And, unlike petrol or diesel, there was almost no black soot or odour.
