Cleaning Up: Leadership in an Age of Climate Change

Can the Philippines become a testbed for Southeast Asia’s clean-tech future?

Kicking off Season 19 of Cleaning Up, guest host Marie Cheong meets Jaime Z. Urquijo, Urban Estates Group Head at Ayala Land, one of the Philippines is largest real estate and development companies.

Ayala Land is a subsidiary of the Ayala Corporation, which has been part of the Philippines' economic story for almost 200 years, and ACEN, its energy platform, has gone from a standing start in 2011 to more than 7GW of renewable capacity across Asia-Pacific.

Marie and Jaime explore how the Philippines can build cleaner energy, transport and cities from the start while its economy and population continue to grow. They discuss replacing coal with renewables, retiring coal plants early, building resilient cities and making growth less carbon-intensive. From batteries and rooftop solar to green steel and electric buses, they ask what it will take for the Philippines to leapfrog to a cleaner, more resilient economy.

Topics covered in this conversation:

The Philippines' clean-energy challenge

Can growth be decoupled from emissions?

Making corporate sustainability profitable

ACEN's renewable-energy transformation

Southeast Asia's renewable-energy gold rush

Can coal plants retire early?

Building resilient cities for climate

Electric buses and better transport

Green steel and cleaner construction

Australia has become a laboratory for the energy transition, what can the rest of the world learn? After two weeks travelling across Australia and meeting the leaders shaping its energy transition, Michael Liebreich got a close up view of the country’s transformation.

For the final episode of Cleaning Up’s Deep Dive Australia series, the host becomes the guest as Anna Freeman of the Energy Efficiency Council turns the tables and puts Michael in the hot seat to ask him what he has learned.

Michael divides his takeaways into the good, the less good and the “downright ugly”, from Australia’s extraordinary rooftop solar and battery uptake to its struggles with wind, transmission and diesel. He also asks whether the country really can become a clean energy superpower, and what its successes and failures can teach the rest of the world.

Topics covered in this episode:

Australia’s rooftop solar advantage

Why batteries are beating gas

The missing middle of electrification

Can transmission keep up?

Australia’s expensive wind problem

The China challenge

Breaking the diesel addiction

Why EVs may be finally taking off

Around the world, factories making food, drink, pharmaceuticals and other everyday products rely on steam, often produced by fossil-fuel boilers. James Macnaghten, founder and CEO of Caldera, is betting that thermal batteries can provide a cheaper and more flexible alternative that stores electricity as heat, and delivers steam on demand.

This week on Cleaning Up, Bryony Worthington visits Caldera's factory to see how it makes its heat batteries: combining recycled aluminium and iron ore pellets to create a long-lasting, efficient heat store. The technology is designed for industrial processes up to 200°C, which James sees as a major opportunity for electrification.

They discuss how thermal storage can help factories manage peaks in demand, use electricity when it is cheap or abundant, and reduce pressure on congested grids. They also explore Caldera's plans to scale, its journey from domestic heating to industry, and why James believes a more pragmatic approach to electrification is needed.

Topics discussed in this episode:

The hidden opportunity in industrial heat

How Caldera's heat batteries work

Why steam still matters

Heat pumps and thermal storage

Managing industrial demand spikes

Turning surplus power into heat

Scaling a UK climate-tech company

The case for pragmatic electrification

Solar was once dismissed as a marginal technology. Today, it is transforming the global energy system, and few people have done more to make that possible than Professor Martin Green. Innovations developed by Green and his research group can now be found in over 90% of all the solar panels in use today

One of the pioneers of modern solar power, Green’s research has helped make solar panels dramatically more efficient and cheaper to produce. He joins Michael Liebreich to discuss how he got into solar, the breakthroughs that helped drive its extraordinary rise, and the remarkable story of how research carried out at an Australian university helped create the global solar manufacturing industry. They also look at where solar goes next, and whether the next generation of technology can make it even more powerful. 

Topics discussed in this episode

The breakthroughs that changed solar

Understanding solar cells and efficiency

Racing NASA to new efficiency records

Pioneering PERC and TOPCon technology

How solar technology reached the market

Suntech and the rise of Chinese solar

The future of solar and batteries

Which solar technology will dominate?

Will AI break the grid? As hyperscalers race to build ever-larger data centres, electricity demand is soaring. The question is no longer whether power demand will grow, but by how much, how quickly, and whether the grid can deliver.

This week, Michael Liebreich is joined by Arshad Mansoor, President & CEO of the Electric Power Research Institute (EPRI), one of the world's leading energy research organisations. Together, they tackle one of the biggest questions facing the global energy system: how much electricity will AI really need, and can our power systems keep up?

They debate the scale of AI-driven demand growth, whether the extraordinary investment by hyperscalers is justified, and how greater flexibility could allow data centres to connect faster without overwhelming the grid. They also discuss the growing public backlash against AI infrastructure, why winning local support may become the industry's biggest challenge, and whether nuclear power is truly the "get out of jail free card" many believe it to be or simply one part of a much bigger solution.

Topics included in this episode:

The race to power AI data centres

Hyperscalers' trillion-dollar AI investment

Can electricity grids keep pace with AI's rapid growth?

Gigawatt demand forecasts

Making data centres more flexible

Public acceptance and the growing backlash against AI

Nuclear power's role in the AI era

What governments, utilities and investors should do next
