Watt? A Geoheat Strategy for NZ

Abstract

Geothermal energy is a vital component of New Zealand’s energy scene. The development of a geoheat (earth energy) strategy for New Zealand will create opportunities for increased use of geothermal energy. This is particularly relevant in the current context of long term increases in energy costs, changing social views towards energy use, substitution opportunities for CO2 rich fuels, future growth in energy demand and government strategies promoting renewable energy. Electricity generation from geothermal resources is well-established; New Zealand is internationally recognised for our experience and expertise. Conversely, we are lagging behind in the use of geothermal resources for direct use applications and for heating and cooling using geothermal heat pumps. A geoheat strategy could assist in driving the uptake of direct heat and geothermal heat pump use in New Zealand. A robust strategy will be a growth enabler with associated economic, social and environmental benefits. To succeed, this strategy will require a common vision, collaboration and leadership. The New Zealand Geothermal Association has a key role to play. This paper discusses the development of a New Zealand geoheat strategy to further empower uptake of geothermal energy. A strategy developed and owned by the geothermal community will inspire New Zealand to reach beyond business as usual.
