[Episode #249] – Solar Innovation in Australia

May 7 2025

Mini Episode

This episode continues our miniseries on Australia’s energy transition.

In late 2024, Chris traveled to Australia and recorded interviews with a wide range of experts who are intimately involved in the energy transition there. Previous episodes in this miniseries are Episode #234, Episode #235, Episode #246, and Episode #247.

In this episode, we feature three researchers and entrepreneurs in Australia who are advancing solar technology research and development:

  • Martin Green, Professor at University of New South Wales, Sydney and Director of the Australian Centre for Advanced Photovoltaics.
  • Craig Wood, CEO of Vast Energy, a concentrated solar thermal power (CSP) company.
  • Richard Payne, CEO of RayGen, a concentrated solar PV and solar thermal company.

In the next and final episode in this miniseries, we’ll take a close look at how one Australian state is solving the challenges of knitting together customer-owned systems into a reliable power grid.

Guest #1:

Craig Wood is the CEO of Vast. Craig has led Vast since 2016, proving the internationally awarded solar thermal technology at a Pilot Plant in regional NSW and leading the development of Vast Solar’s first utility-scale plant in Mount Isa, Queensland.

Craig is an experienced leader with a background in corporate management, structured finance and the energy and technology sectors. Prior to joining Vast in 2015, he worked in London, NewYork, Sydney and Perth and has held leadership roles in diverse industrial and manufacturing organisations including Browne’s Dairy, Archer Capital, and Lehman Brothers.

Guest #2:

Dr. Martin Green is Scientia Professor at the University of New South Wales, Sydney and Director of the Australian Centre for Advanced Photovoltaics, involving several other Australian Universities and research groups. His group’s contributions to photovoltaics are well known and include holding the record for silicon solar cell efficiency for 30 of the last 39 years, described as one of the “Top Ten” Milestones in the history of solar photovoltaics. The PERC solar cell that he invented in 1983 and his team developed to its full potential accounted for 91.2% of worldwide silicon solar module production in 2021 (CPIA).

Major international awards include the 1999 Australia Prize, the 2002 Right Livelihood Award, also known as the Alternative Nobel Prize, the 2007 SolarWorld Einstein Award, the 2016 Ian Wark Medal from the Australian Academy of Science, the prestigious Global Energy Prize in 2018, the 2021 Japan Prize, the 2022 Millenium Technology Prize and, with three former students, the 2023 Queen Elizabeth Prize for Engineering.

[Episode #247] – Energy Innovations in Australia

Apr 9 2025

Mini Episode

This episode is part of a miniseries about Australia's energy transition.

In late 2024, Chris traveled to Australia and recorded interviews with experts closely involved in its energy transition. The first of those interviews was featured in Episode #234, and the second in Episode #235. In Episode #246, we explored how the Australian government is working with the grid power sector to plan its transition to renewables while maintaining system reliability.

In this episode, we explore innovative approaches Australia is using to manage the evolution of its energy system.

To tell this part of the story, we weave together the perspectives of several guests:

  • Darren Miller, CEO of ARENA, explains their investment focus on early-stage technologies.
  • Gabrielle Kuiper, energy and climate change professional, shares insights on DER integration across Australia.
  • Stephanie Unwin, CEO of Horizon Power, discusses the unique challenges of managing a remote utility in Western Australia.
  • Professor John Boland describes how he and his wife used low-tech solutions to transform an uncomfortable old house into a comfortable urban oasis.

In the next miniseries episodes, we'll explore more innovations in solar power and take a close look at how one Australian state is solving the challenges of knitting together customer-owned systems into a reliable power grid.

Guest #1:

Darren Miller has been the Chief Executive Officer of the Australian Renewable Energy Agency (ARENA) since 2018. With 30 years’ experience across renewable energy, electricity retail, technology, finance, media and entertainment, Darren has led ARENA into new strategic areas.

[Episode #71] – Australia at the Cutting Edge

Jun 13 2018

Mini Episode

Since we last covered Australia one year ago in Episode 39, a lot has changed…it has deployed the largest utility-scale battery system in the world, made numerous technical upgrades to prevent future outages, and placed some incredible leaders in key agencies where they are working hard to accelerate the country’s energy transition. It is also actively investing in new energy technologies that aren’t even commercial yet, to see how they can perform. In short, Australia is breaking new trail on multiple fronts in energy transition, and demonstrating some truly interesting findings to the rest of the world, for how a grid might function self-sufficiently, at scale, with significant shares of variable renewable power and large battery storage systems.

Our guide to the current state of affairs today is Ivor Frischknecht, a subscriber to this show and the CEO of the Australian Renewable Energy Agency (ARENA). A widely acknowledged expert and innovator in the energy industry, with deep knowledge of the grid’s needs in Australia, and a far-reaching vision for what it can become, he’s one of the top experts on the energy transition Down Under, and can explain it all in a very accessible way.
