By David Dempsey, Associate Professor in Natural Resources Engineering, University of CanterburyNew Zealand’s North Island features a number of geothermal systems, several of which are used to generate some 1GW of electricity. But deeper down there may be even more potential. The government is now investing NZ$60 million to explore what is known as “supercritical” geothermal energy, following five years of feasibility research led by GNS Science.

AbstractSeismic data recorded before volcanic eruptions provides important clues for forecasting. However, limited monitoring histories and infrequent eruptions restrict the data available for training forecasting models. We propose a transfer machine learning approach that identifies eruption precursors—signals that consistently change before eruptions—across multiple volcanoes.

The Emissions Trading Scheme would have been a better tool to reshape the energy market and cut emissions than an outright ban – and most new exploration had largely dried up already. Read complete article© The Conversation

Historically, gas in New Zealand traded below NZ$10 per gigajoule. When prices hit $50 per gigajoule in August this year, anyone with gas to sell could have made a lot of money. But there clearly wasn’t much gas around. In the end, the big generators Genesis and Contact had to buy gas off Methanex to keep the lights on. How did this happen? It’s tempting to blame the previous government’s ban on offshore oil and gas exploration.

By Jannik Haas, Andy Nicol, David Dempsey, Ian Wright, Matthew J Watson & Rebecca Peer*Hydrogen has been called the “Swiss army knife” of decarbonisation because it can do many things. But not all of them make sense. Today, the world uses about 100 megatonnes of hydrogen per year (MT/y), but this is produced almost entirely from fossil fuels. To use hydrogen for decarbonisation, we must shift to emissions-free forms.

The coalition government recently announced its plan to reverse a ban on new oil and gas exploration to deal with an energy security challenge brought on by rapidly declining natural gas reserves. But this assumes, rather optimistically, that repealing the ban will prompt companies to invest in new gas fields. In practice, those companies will be carefully considering whether there is anyone to sell their gas to, or whether a future government could change the rules again.
