Mercury, Contact Lead NZ's Supercritical Geothermal Energy Revolution

🌋 From the Ground Up: New Zealand’s Bold Leap into a Supercharged Geothermal Future

By: Robert Buluma

In the heart of New Zealand, beneath the rugged volcanic landscapes and steaming geysers, lies an energy revolution waiting to erupt. On July 30th, 2025, a powerful message echoed from the geothermal capital of the Southern Hemisphere — New Zealand is not just embracing its geothermal potential; it is preparing to unleash it.

With the unveiling of the draft strategy titled From the Ground Up, the government, led by Minister Shane Jones for Resources and Regional Development, signaled a transformative shift in how the nation will harness the heat beneath its feet — and it's as ambitious as it is inspiring.


🔥 A Legacy Forged in Steam

New Zealand’s geothermal story is deeply rooted in its identity. Long before turbines spun and power grids buzzed, Māori ancestors were using geothermal waters for warmth, healing, and cooking. Geothermal, or waiwhatu, is more than a resource — it is a taonga, a treasured gift linking the spiritual and physical worlds.

From the pink and white terraces to post-WWII geothermal engineering breakthroughs, New Zealand has consistently been at the forefront of global geothermal innovation. The iconic Wairākei Power Station, built in 1958, was only the second of its kind in the world and a pioneering attempt to utilize wet steam.

Fast forward to today, and geothermal power provides nearly 20% of the nation’s electricity — positioning New Zealand as the fifth largest geothermal energy producer globally.


💡 A Sleeping Giant Awakens

Despite this legacy, Minister Shane Jones issued a striking challenge during the launch: “What’s holding us back from geothermal being the answer to all our problems?

The answers came swiftly:

  • Lack of accessible exploration data
  • High upfront investment risks
  • Outdated regulatory frameworks
  • A fragmented, unambitious approach

But that changes now.

The Government’s draft strategy aims to double geothermal energy use by 2040, transform regional economies, support Māori aspirations, and embed geothermal into every layer of New Zealand’s energy transition.


🧠 Strategy + Science = Supercritical Possibilities

The boldest leap? Supercritical geothermal energy — the next frontier.

This revolutionary technology could yield up to three times the energy of conventional geothermal systems. To test this promise, the Government has allocated $60 million from the Regional Infrastructure Fund to begin exploring this untapped power source in the Taupō Volcanic Zone — a region where Earth’s heat lies closest to the surface.

With $5 million already committed to designing the country’s first deep supercritical well, drilling is set to commence in 2026. Collaboration with Māori communities, top research institutions like Earth Sciences New Zealand (formerly GNS Science), and geothermal powerhouses Mercury and Contact Energy ensures this isn’t just a dream — it’s a deep-earth mission in motion.


🌱 More Than Just Power

Geothermal energy in New Zealand is more than electricity. It supports:

  • Industrial processing – from paper and wood to dairy and greenhouses
  • Tourism – with 27% of international tourists visiting geothermal attractions
  • Cultural revival and Māori-led innovation – from the Tūaropaki Trust’s hydrogen production to Ngāti Tuwharetoa’s global leadership in direct heat supply
  • Aquaculture – like the world-famous geothermally-heated Huka Prawn Park

And with the new strategy, geothermal energy is poised to become a pillar of national resilience, regional revitalization, and climate-conscious economic development.


📣 Have Your Say – The Future is Collective

The draft strategy is now open for consultation. The government is calling on stakeholders, Māori leaders, energy experts, entrepreneurs, and innovators to help shape a cohesive, inclusive, and actionable plan.

🌋 Final Thoughts: A New Dawn from Below

New Zealand has always been a land of geothermal marvels — from steaming mud pools to world-first engineering feats. But now, with From the Ground Up, the country is no longer just tapping into geothermal — it's preparing to ignite a geothermal renaissance.

In the words of Minister Jones, “The opportunities in front of us are limitless.” And as we edge closer to the supercritical era, one thing is clear: the ground beneath New Zealand isn’t just hot — it’s humming with the energy of a cleaner, bolder future.

Driving the UK Toward Net Zero: Chris Sladen on Geothermal’s Untapped Potential

Alphaxioms, we talked to Chris Sladen about his involvement in geothermal both in the UK, and globally By:  Robert Buluma Chris, please begin by explaining a little about yourself, and why you have a passion for geothermal? I have spent over 45 years involved in energy. Following undergraduate studies in geology at Southampton University, and a PhD in sedimentology at Reading University, I joined the energy sector in Aberdeen in 1980. It was a fascinating era when it seemed like at least one giant oil & gas field was discovered offshore every month; the wealth creation for the UK was gigantic. I got to see so much geology and rocks - my true passion. I moved to China in late 1983; not today’s China, this was over 40 years ago, a country closed for decades and embarking on an open-door policy, in part to bring both investment and technology. I became very interested in energy trends, energy politics, and new geography created by changing politics leading to opportunities for ene...

Unlocking Geothermal Power: Subsurface Secrets of Mount Erciyes Revealed”

Mount Erciyes: A Hidden Geothermal Treasure Beneath Cappadocia By: Robert Buluma Beneath the snow-capped slopes of Mount Erciyes , central Turkey’s highest peak, lies more than just volcanic history  it harbors the promise of geothermal energy . A new study published in the Journal of Volcanology and Geothermal Research has mapped the subsurface of Erciyes using three-dimensional magnetotelluric (MT) imaging , revealing zones of high electrical conductivity that point to heat, fluids, and possible magma bodies deep underground. Cracking the Code Beneath the Mountain Researchers led by S.B. Tank used advanced MT techniques to peer beneath Erciyes and its surroundings. Their results uncovered conductivity anomalies   regions where electricity flows more easily due to the presence of saline fluids, hot water, or partially molten rock . For geothermal experts, these anomalies are gold. They act as subsurface fingerprints of geothermal reservoirs , highlighting where heat ...
