  Stack ‘em up: Germany’s big battery inflection point – with Thaddäus Kreisig 17.09.2026 30мин

  Germany’s utility-scale battery deployment is hitting an inflection point. After years of projects piling up in development pipelines, utility-scale storage is arriving at gigawatt scale – just as Germany’s huge solar fleet drives electricity prices towards zero, or below, during sunny hours. For batteries that can shift that power into higher-priced periods, the opportunity is enormous. Host Jonathan Gifford speaks with Thaddäus Kreisig, Principal at Aurora Energy Research, about Germany’s forming battery boom – and how developers are building revenue stacks to make projects viable. The shift is striking: more than two-thirds of solar developers recently surveyed by Aurora said every project they plan to deploy will be co-located with a battery system. Falling battery-system equipment costs are strengthening the business case, while arbitrage, ancillary services, EEG revenues, and new financing models are opening up ways in which battery energy storage systems can pay off. But grid constraints remain a major hurdle. Flexible connection agreements can restrict when batteries charge and discharge – limiting revenues, even as energy storage could help resolve the German energy market’s pricing peaks and troughs. In short, Germany’s massive solar fleet has created both the need and the opportunity for batteries. And energy storage is rapidly shifting from optional extra to essential infrastructure – but the route-to-market for projects certainly promises to be an interesting ride. ✉️ Questions, comments or suggestions?

  Update on global solar and inside “24/7 renewable Germany” – with Charlotte Senkpiel & Sonia Dunlop 03.09.2026 30мин

  The Dunkelflaute has become one of the most persistent arguments against a fully renewable energy system. When the sun isn’t shining and the wind isn’t blowing, where is our energy supposed to come from? Detailed new modeling from Germany’s Fraunhofer ISE suggests these “dark doldrums” are a challenge – but should not be enough to halt the energy transition. The bigger challenge to be overcome is how the flexibility needed to manage low-renewable energy periods can be embedded into the country’s energy system. Recorded at The smarter E Europe 2026 in Munich, host Jonathan Gifford speaks with Fraunhofer ISE senior scientist Charlotte Senkpiel about what it would take for Germany to reach climate neutrality with wind and solar at the heart of its energy system. And the result is not only good for the climate, it’s economically viable. The outcome of the Fraunhofer ISE study goes well beyond simply building more renewables. Batteries, electric vehicles, flexible demand, strengthened and smarter grids, international interconnectors, and dispatchable backup all have roles to play – while electrification dramatically reduces Germany’s dependence on fossil-fuel imports. And when prolonged periods of low wind and solar do arrive? The modeling shows how batteries, demand flexibility, electricity imports, and a limited use of hydrogen or synthetic-fuelled generation can work together to keep the system running. In the second part of the podcast, Global Solar Council CEO Sonia Dunlop joins the episode to discuss the push to unlock agrivoltaics and rooftop solar worldwide – and why she believes a near-term slowdown in global PV deployment doesn’t change solar’s mid-term trajectory. What the episode crystallizes: a 24/7 renewable energy system is about building an energy system flexible enough to handle the variability of wind and solar, and how it’s cheaper to do so. ✉️ Questions, comments or suggestions?

  Why modelling the energy transition matters – with Jarand Rystad 20.08.2026 22мин

  Despite claims that the energy transition is losing momentum, solar and battery deployment continues to run ahead of forecasts – profoundly impacting electricity markets and the wider global energy system. Recorded at The smarter E Europe 2026 in Munich, host Jonathan Gifford is joined by Jarand Rystad, founder and CEO of energy analysts Rystad Energy, to examine where the transition stands today. Rystad explains why solar has consistently outpaced forecasts and how mass production, aggressive cost reduction, and rapid battery-technology deployment are driving continued expansion. But alongside the upside, the conversation turns to one of solar's biggest challenges: falling capture prices as abundant midday PV generation pushes down the value of electricity during daylight hours. Rystad argues that accelerating battery deployment is helping to address this imbalance, shifting excess generation, and ultimately making space for even more renewables. The conversation also explores how storage business models are evolving, the prospects for European solar manufacturing and next-generation perovskite technologies, and whether energy-security concerns could further accelerate the electrification of transportation. Together, these trends point to solar and batteries increasingly working in tandem to create a cheaper, flexible, and electrified energy system. ✉️ Questions or feedback?

  Keep calm and deploy solar (and batteries) – with James Allston and Marko Topič 30.04.2026 47мин

  With the Strait of Hormuz disruption continuing to drive fossil-fuel costs higher, businesses big and small have been left looking for ways to cut energy costs. But, in contrast to energy crises of the past, today’s clean energy technology is mature, cost competitive, and ready to fill the gap. This week on the pod, we speak to James Allston of Orkestra Energy for a view on how European businesses are responding to sustained high electricity prices and growing volatility. Rather than reacting to headlines, he explains how structural forces – from rising network charges to falling battery costs – are accelerating the business case for solar and storage. We unpack how local market dynamics, in leading commercial and industrial (C&)I marketplaces such as the United Kingdom and Germany, are shaping very different “value stacks” for batteries, including managing peak demand, navigating negative pricing, and optimizing behind-the-meter savings. We also explore the next frontier for commercial energy users: EV fleets with integrated on-site solar and storage. As grid capacity tightens and electrification accelerates, this convergence will likely shape how businesses think about both energy costs and transportation. Then, we shift from deployment to innovation with renowned solar researcher Professor Marko Topič from the University of Ljubljana, who takes us inside one of the most promising areas of solar research: perovskite solar cells. With record-breaking efficiencies already achieved, industry focus has turned to the next challenge for the emerging solar technology: durability. We dive into the perovskite degradation mechanisms, surprising “self-healing” behaviors, and the painstaking work required to understand, and ultimately control, these processes in real-world conditions. Professor Topič discusses indoor perovskite-powered IoT devices and even space applications, providing a glimpse into an exciting future – but one that will only be realized if researchers can bridge the gap between lab performance and long-term reliability. ✉️ Questions or feedback?

  Beating the blockade with EVs and batteries – with Gautham Ram and Ruben Valiente 16.04.2026 45мин

  As global energy markets face renewed volatility – from geopolitical flashpoints to supply disruptions – a key question is back in focus: how do we deliver energy security when fossil-fuel supply is no longer guaranteed? In this episode, we explore how flexibility – powered by EVs and batteries – is emerging as a frontline solution to energy security challenges. First, Gautham Ram (TU Delft) changes the narrative on EVs as a grid liability. Instead, he outlines how millions of electric vehicles could act as a vast, distributed storage network, effectively turning transport into a strategic energy asset. From smart charging to V2G, we explore how intelligent coordination – and not just new infrastructure – can ease grid congestion, absorb renewable generation, and reduce reliance on imported fuels. We also unpack the use cases driving AC vs. DC charging, bidirectional technology, and battery lifetimes – and why scaling these solutions will depend on standards, interoperability, and consumer confidence. Then, live from the Battery & Business Development Forum 2026 in Frankfurt, Ruben Valiente of Maxxen Energy shares a ground-level view of Europe’s rapidly expanding battery storage market. His message is timely: while battery cells remain dominated by global supply chains, Europe’s strength lies in system integration, local engineering, and getting projects deployed rapidly. As markets grapple with uncertainty, new approaches like vendor-backed financing are helping to de-risk investments and accelerate deployment, which is absolutely critical in these moments when resilience is thrown into question. With EV fleets increasingly acting as mobile energy reserves and utility-scale batteries stabilizing grids, this episode connects the dots across a rapidly evolving storage landscape and shows how, in an era of disruption, flexibility may be the ultimate hedge against energy insecurity. With a focus on smarter inverters and the power of distributed energy systems, this episode looks at how solar is redefining energy security – and why resilience may be its most important role yet. ✉️ Questions or feedback?

  How solar is delivering energy security – with Timothy Shen and Dr. Rethabile Melamu 02.04.2026 37мин

  Energy security is back at the top of the global agenda and new ways to secure supply are evolving fast. In this episode of The smarter E Podcast, we explore how solar is moving beyond generation to play a critical role in stabilizing power systems and delivering energy security. First, Wood Mackenzie analyst Timothy Shen breaks down the rapid evolution of solar inverters – and how they are well equipped to meet the challenges of today’s changing power mix. Once seen as passive components, today’s advanced inverters can actively support the grid managing voltage, frequency, and providing reactive power in real time. As the energy transition accelerates, these capabilities are becoming essential to keeping power systems reliable, especially during disruptions. We also examine what recent grid failures reveal about the gap between older infrastructure and newer, more resilient technologies, and why the latest generation of inverters could help prevent future blackouts. In the second half of the episode, Dr Rethabile Melamu from the South African Photovoltaic Industry Association shares insights from Africa’s rapidly accelerating solar market. With hundreds of millions still lacking access to electricity on the continent, solar and storage are an increasingly essential factors to support economic growth, energy access, and resilience. From community-led microgrids to innovative financing models, new approaches are enabling decentralized, secure power systems to scale quickly across Africa.

  Digitalizing the grid to meet today’s energy crisis – with Simon Evans and Akshat Rathi 19.03.2026 57мин

  As geopolitical tensions once again send shockwaves through global energy markets, the pressure to accelerate the energy transition has rarely been greater. In this episode of The smarter E Podcast, we explore how digital technologies and electrification are reshaping the energy system—and why smarter, more connected grids are becoming essential in navigating today’s crisis. Our first guest, Simon Evans, Global Digital Energy and Digital Twin Leader at Arup, explains what digitalization really means for electricity networks. As renewables, rooftop solar, EVs, and distributed assets multiply across the grid, traditional operating models are becoming increasingly complex. Digital technologies, including improved data sharing to digital twins and machine learning, can help system operators manage this growing complexity. But as Evans argues, the biggest hurdles are not technical. Regulatory frameworks, trust between stakeholders, and new approaches to secure data exchange will ultimately determine how quickly digitalization can scale. We also explore how smarter networks could unlock flexibility across the system like coordinating EV charging and distributed storage and reducing renewable curtailment. In some cases, digital tools could even help direct excess renewable generation toward households facing energy affordability challenges. In the second half of the episode, Bloomberg climate reporter Akshat Rathi joins the podcast to unpack the geopolitical context behind today’s volatile energy markets. As disruptions to oil and gas supply chains push prices higher, governments are once again confronting energy security concerns. But unlike past crises, there is now a third option: accelerating electrification and renewable energy deployment. From digital grids to geopolitics, this episode looks at how today’s energy shocks could reshape the power system and why smarter infrastructure may be key to building a more resilient, electrified energy future. ✉️ Have comments or questions?

  Are today’s solar modules built to last? – with Chiara Baretta and Steven Xuereb 05.03.2026 46мин

  Recorded live in Barcelona at the Solar Quality Summit in February, this episode of The smarter E Podcast examines a critical question for the PV industry: are today’s solar modules built for long-term durability? As manufacturers push for higher efficiencies, larger formats, and lower costs, quality data is flashing warning signs. Drawing on insights from Kiwa PI Berlin’s latest Module Manufacturing Report, we explore a record 3.36% defect rate observed during pre-shipment inspections in 2025, and what’s driving it. Rear-side breakage in large-format, glass-glass modules is emerging as a major concern, with thinner 2 mm strengthened glass proving more fragile under real-world stress. At the same time, thinner frames, rapid factory ramp-ups, and geopolitical supply chain shifts are adding new layers of risk. The episode also dives into degradation challenges linked to TOPCon technology, including UV-induced degradation – and module meta-stability, which is proving challenging for accurate characterization. In the second part of the episode, we turn to polymers – present in the encapsulants, backsheets, and adhesives that quietly influence whether modules last 30 years or fail early. New materials like POE and TPO are improving performance in some areas, but increasing complexity across the bill of materials. Meanwhile, emerging tools such as near-infrared field analysis and AI-supported inspection may help be a helpful root-cause analysis tool and enabler of predictive maintenance. If solar is scaling at unprecedented speed, quality assurance must keep up. Covering a wide range of the important quality topics at hand, our live conversation Barcelona puts the spotlight on what it will take to ensure today’s modules truly stand the test of time. ✉️ Have comments or questions?

  Battery capacity is going through the roof – with Carolina Cruz and Pete Tillotson 19.02.2026 44мин

  Battery capacity is getting bigger, storage duration longer, and batteries more central to how power systems operate. In this episode of The smarter E Podcast, we look at what’s driving the surge in battery capacity and why expectations for storage are shifting so quickly. Projects that would have seemed unrealistic just a few years ago are now moving into planning and achieving financial close. Lithium-ion batteries are expanding well beyond traditional short-duration applications, as falling costs and ongoing technical progress make longer discharge durations commercially viable. At the same time, rising renewable penetration is exposing a new challenge: extended periods when the power output from wind and solar output is low, for extended periods, and at the same time (the dreaded Dunkelflaute). These events are forcing system operators, utilities, and policymakers to rethink how much storage is needed – and for how long. The episode also explores the structural side of the transition: how market design, revenue certainty, and permitting timelines could ultimately decide how fast large-scale storage rolls out, and which technologies win the arms race. If the last decade was about proving that storage can, in fact, work – the next may be about proving that it can actually play a central role in helping manage power systems. ✉️ Have comments or questions?

  Has Vehicle-to-Grid Reached the Tipping Point? – with Adriana Fricke and Robin Berg 05.02.2026 38мин

  In this episode of The smarter E podcast, we unpack how bidirectional EV charging is reshaping Europe’s energy and mobility landscape, from market signals to real-world deployment at scale. We begin with a policy perspective, speaking with Adriana Fricke from Hubject – a company that is working at the intersection of e-mobility, regulation, and energy systems. As Europe pushes toward electrification, regulatory standardization and cross-industry alignment are emerging as critical enablers of bidirectional charging. And with hundreds of billions already invested into the EV ecosystem, the sector is moving beyond theory to now positioning EVs as the mobile energy assets that will support grid stability, cut system costs, and strengthen energy resilience across Europe. In the second part of the episode, we speak to Robin Berg, the Founder and CEO of We Drive Solar, about the shift from concept to practice by exploring how V2G is being deployed on the ground. We look at the rapid scale-up of bidirectional EV fleets in the Netherlands and what they reveal about the future of distributed storage. Fleet vehicles – stationary for most of their lifetime – are proving uniquely suited to providing grid flexibility, helping manage winter demand peaks and absorb excess solar during high generation periods. As projects scale from pilots to hundreds of vehicles, they are offering a glimpse of how V2G could become a core part of future power systems. These conversations show how V2G is transitioning from experimentation to commercial rollout – and why standards and policy clarity will be crucial to shaping how fast it scales. 🎧 Follow The smarter E podcast for expert insight into solar, storage, e-mobility, and the global energy transition – and don’t forget to rate and review if you enjoy the show! ✉️ Have comments or questions?
