Where China goes, so goes the global energy transition. With its dominance across solar and energy storage supply chains, China’s every policy shift ripples through global clean tech markets.

In 2025, that landscape is shifting fast: after nearly 200 GW of new solar capacity added early in the year, installations have slowed as the industry adapts to new policies. Meanwhile, manufacturers are facing overcapacity and hunting for new export markets.

Frank Haugwitz, Senior Analyst at cleantech advisory Apricum, joins host Jonathan Gifford to break down the latest trends – and what to expect from China’s renewable energy industry through the end of the decade.

Today, we dive into one of the most exciting areas of the energy transition: the expansion and optimisation of our power grids and the role that startups play in this. There's no question that the big players in the energy industry are important. But more and more often, it's the young, courageous companies that are driving change in the system with fresh ideas, new technologies, and unusual business models.

However they need tackle quite a few hurdles on their way. How do start-ups manage to assert themselves in a highly regulated and technically demanding industry? How do they work with grid operators, municipal utilities, or energy suppliers, and where do they encounter resistance?

Today, we're examining a region that's rarely in the spotlight in the international energy debate, yet has enormous potential: Central Asia. Specifically five countries characterised by a long tradition of fossil fuels, but also by an abundance of sun, wind, and water: Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan, and Turkmenistan. Are these countries already tapping into their potential for a sustainable energy future? We’ll get up to speed in regards to their political strategies and investment programs driving the transformation. What are the biggest hurdles in terms of regulation, financing, and infrastructure? How important are international partnerships in making this region a key player in the global energy transition? We talk about this with Elena Metzger.

Betreiber von Solaranlagen kommen künftig kaum an PV-Heimspeichern vorbei. Gründe sind das Auslaufen der EEG-Förderung, das neue Solarspitzengesetz und variable Stromtarife. Damit sich PV-Anlagen weiterhin rechnen, muss der Solarstrom zwischengespeichert werden. Dabei werden zumeist traditionell DC-Speicher und Wechselrichter verbaut. SAX Power bietet dazu eine Alternative: Einen AC-Stromspeicher, der direkt 230 Volt Wechselstrom liefert, ohne den sonst üblichen Hybridwechselrichter.

Über diese Innovation unterhalten wir uns mit Marc Gretzinger, leitender Elektronikentwickler bei SAX Power.

Über Marc Gretzinger

Marc Gretzinger hat sich schon während seines Elektrotechnikstudiums intensiv mit der Auslegung und dem Aufbau von PV-Anlagen beschäftigt und ist mittlerweile als leitender Elektronikentwickler bei SAX-Power tätig.

Über Sax Power

Die Anfänge des Unternehmens liegen in Ulm. Als langjähriger Partner der Deutschen Bahn hat die Firma SAX vor über 25 Jahren als einziger Lieferant die Entwicklung und Produktion der Regeleinrichtungen für Umrichterwerke im deutschen Bahnstromnetz übernommen. Das Unternehmen hat die Erfahrung aus den Bahnstromumrichtern genutzt, um die SAX-Technologie für Lithium-Ionen-Batteriespeicher entwickelt.

SAX Power hat den weltweit ersten Heimspeicher erschaffen, der direkt 230 Volt Wechselstrom liefert. Seine intelligente Multi-Level-Technologie wandelt die Gleichspannung der Lithium-Eisenphosphat-Batteriezellen im Speicher direkt in Wechselspannung um. So entfällt die aufwendige Installation eines Hybrid-Wechselrichters, der bei allen bisherigen Heimspeichern zwischen Batterie und Hausstromnetz notwendig ist.

The European energy system is undergoing profound change, driven by the urgent need to combat climate change and secure a sustainable energy future. Underneath initiatives such as the European Green Deal this transition, opens up enormous opportunities but also brings with it considerable complexities. One Key to Smart grids is central to effectively managing this change, and smart grids - modernised electricity infrastructures that integrate digital technologies. So what is the transformative potential of artificial intelligence (AI) and generative AI (GenAI) in the context of European smart grids? What can AI achieve? How AI also improve collaboration with humans in this area? And where are the dangers? We talk about this with Luís Vale Cunha.

“Every solar panel is also a gateway to digital justice,” says Payel Farasat. But what does AI have to do with renewable energy? More than we think. AI is not neutral—it reflects our networks, our data, and our values.

By 2050, one in four people on Earth will be African. Yet nearly 600 million people in sub-Saharan Africa still live without electricity.

The next wave of AI inclusion will not be driven by new models in Silicon Valley – it will be driven by access to renewable energy in schools, clinics, and communities around the world.

In our latest episode of The smarter E podcast, Payel Farasat explains why energy justice is the foundation for digital justice – and why Europe's leadership in renewable energy can become a global bridge.
