Energy Beneath Our Feet

Over the next three years, New Zealand public research institute GNS Science will explore the potential of harnessing the low-energy geothermal energy produced by underground steam and water systems. GNS Science is to develop technologies for locating and tapping low-temperature heat sources, which refers to temperatures below 150°C, with some below 80°C. Project leader Brian Carey said New Zealand’s landmass is a large source of heat, with different types of natural energy available. “Low temperature geothermal resources are widespread throughout New Zealand and there is significant potential to increase their use. They are capable of providing long-term energy and heat supply with low carbon emissions,” Carey said. He said the benefits of harvesting energy this way included low environmental impacts and increased security of supply.
