Redefining Energy

Recorded at the SolarPower Summit in Brussels this conversation between Laurent Segalen and Jonathan Gifford examines why batteries have become one of the fastest growing and most strategically important technologies shaping the global energy transition. Jonathan Gifford is the co-founder of Climate Copy and a wonderful storyteller.  

Laurent unpacks how rapid battery innovation is transforming electric mobility, renewable energy markets, charging infrastructure, and the future operation of electricity grids.  

It has been only nine years since Hornsdale (Tesla – South Australia) 100MW-130MWh made of EV batteries cracked the code. Six months later in China the Jiangsu Zhenjiang first 100MW LFP battery was installed. In Europe and the US, the first large LFP batteries were installed in 2021-2022. Now, LFP has a 95% market share in BESS around the world. For EVs, it is 55% LFP – 45% NMC (80% in China).  

By the end of 2026, we will reach 500GW globally and great forecasters like Jan Rosenow expect 1,000GW by 2030. We see longer duration and the advent of sodium batteries.  

Laurent outlines why electrification is entering a new phase of acceleration. He highlights how falling battery costs, rapid improvements in electric vehicle technology, and the widening economic gap between electricity and fossil fuels are reshaping expectations across the transport sector. This shift is not limited to passenger cars; it increasingly extends to commercial fleets and heavy-duty trucking, where electric trucks are becoming more competitive thanks to lower operating costs, reduced maintenance needs, and improving charging infrastructure.  

He also discusses the growing importance of stationary battery storage in enabling high-power EV charging, increasing grid flexibility, and supporting higher penetration of renewable energy.  

Finally, he explained why Hydrogen will never work in long haul transportation. Simply too expensive.

Michael Barnard welcomes Cornelis Plet, CTO of Grid Systems Integration at GE Vernova, about the technologies reshaping modern power systems and the practical realities of building an electrified future.  

High-voltage direct current (HVDC) transmission, once a specialist solution for narrow use cases, is now becoming a standard building block of the global grid. Increasingly standardised designs are enabling large-scale transfer of renewable power over long distances, yet the industry is still grappling with how to align control systems and operational standards across different vendors and regions.  

A central theme of the conversation is the rise of grid-forming inverters. As traditional synchronous generation retires and is replaced by wind, solar, and batteries, the grid is shifting from mechanical inertia to power electronics. While technical progress is rapid and new grid codes are emerging, true interoperability between systems remains a work in progress, with different implementations still complicating integration at scale.  

The discussion also touches on geopolitics and market dynamics. Investment patterns are evolving, regulatory environments are uneven across regions, and supply chains are adjusting after a period of rapid expansion. Yet across all of this, one constraint stands out more than any other: people. The shortage of experienced power engineers, particularly in system design, protection, and control, is becoming the defining bottleneck of the transition.  

Ultimately, the episode is not only about HVDC or inverters, but about the broader system that surrounds them—standards, institutions, skills, and the accumulated expertise required to keep a highly complex, rapidly changing grid stable. It is a reminder that the energy transition is as much a human and organisational challenge as it is a technological one.

In March 2026, Laurent was invited by Jan Rosenow at Oriel College, Oxford, for a public debate on the energy transition. Held in the College's historic library, the discussion brought together contrasting perspectives on one of today's defining challenges. Jan Rosenow, Professor of Energy and Climate Policy, is renowned for his work on energy efficiency, electrification, and the transition to net-zero energy systems.

Laurent opened by introducing the "Aristotelian Triangle" of the energy debate—Ethos, Logos, and Pathos—arguing that values, evidence, and emotion all shape how people interpret energy issues. Responding to Jan's distinction between energy addition and energy transition, Laurent made two key points.
First, history shows that energy forecasts have repeatedly underestimated transformative innovations, from shale gas and LEDs to solar, electric vehicles, batteries, and AI-driven data centres. His conclusion: humility is essential when predicting structural change.
Second, Laurent presented his "Diocletian Tetrarchy of Energy," pairing Vaclav Smil with Clayton Christensen to represent continuity versus disruption, alongside Daniel Yergin and Michael Liebreich to illustrate the roles of markets, geopolitics, and industrial transformation. He described himself as roughly 70/30 in favour of technological disruption while acknowledging the inertia of existing energy systems.
The discussion also examined the cost of ideology, arguing that opposition to technologies such as offshore wind or nuclear power can shape investment, electricity prices, and energy affordability. It concluded by exploring industrial policy, energy security, and how nations should balance resilience, competitiveness, and comparative advantage in a changing geopolitical landscape.

Although the formal debate lasted just over an hour, the conversation continued long afterwards. This episode captures part of those fascinating exchanges.

During Intersolar (The Smart E), Gerard sat down with Dr Chuan Lu, CEO Astronergy and Director of Chint Group to discuss, from the inside the Chinese Solar revolution. 2026 was Dr Lu and Chint 15th participation to that massive European Exhibit that epitomise the growth of renewables. 18 halls the size of a football fields and more than 100,000 visitors.  

CHINT is a vertically integrated Chinese energy conglomerate whose solar business is profitable, mid-growth, and margin-focused rather than driven by hyper-scale manufacturing. Its portfolio includes Astronergy (modules), CPS (inverters), CHINT Solar (EPC/IPP), and CHINT ANNENG (residential PV), generating approximately $650–700 million in operating profit and implying a valuation of $12–16 billion. Annual growth of 15–20% trails peers but reflects CHINT's focus on profitability, diversification, and disciplined capital allocation. The result is a stable, globally active, Tier 1-certified solar group that operates more like an integrated industrial compounder than a scale-at-all-costs PV manufacturer.  

The modern Chinese solar industry began to take shape around 2006 as a predominantly export-oriented manufacturing sector, driven by demand from Europe and other international markets. As a privately held enterprise, CHINT has operated within a unique ecosystem where entrepreneurial initiative has been complemented by government policy support. A pivotal moment came in 2012 with the introduction of China's Feed-in Tariff (FIT) programme, which stimulated domestic demand and transformed China into the world's largest solar market, creating significant opportunities for companies such as CHINT to expand beyond export manufacturing.  

CHINT's development has also been shaped by China's regional economic and cultural differences. Originating in the entrepreneurial, resource-poor southeast of the country, the company embodies a private-sector culture that contrasts sharply with the coal-dependent, state-controlled industrial base of northeast China.  

Looking ahead, management recognises the challenges posed by overbuilding and excess manufacturing capacity in the utility-scale solar market. In response, CHINT has diversified aggressively into distributed generation through its residential rooftop solar business, CHINT ANNENG, which has installed more than 60 GW of capacity across over 1.2 million rooftops throughout China, positioning the company to benefit from a broader and more resilient mix of solar market opportunities.

Laurent and Gerard set out to explore one of the biggest ideas emerging alongside the excitement around the SpaceX IPO: datacenters in space. To refuel those satellites emerged the concept of an orbital grid where beams are directed to provide electricity to space crafts, like a gas station in space.  

It may sound like science fiction, but it is rapidly becoming a medium-term engineering challenge being tackled by some of the brightest minds of our generation.  

One of those pioneers is Andrew Rush, CEO of Star Catcher, a company building what will become the world's first orbital energy grid—a network of satellites capable of wirelessly transmitting power to other spacecraft on demand hundreds of kilometres away.   Andrew is the man for the mission: he previously served on the Technology, Innovation and Engineering Committee of the NASA Advisory Council, helping advise NASA's Administrator, the Office of the Chief Technologist, and its Mission Directorates. Before founding Star Catcher, he successfully built and exited two leading space companies: Redwire and Made-In-Space.  

His vision is ambitious: create an "energy-as-a-service" platform for space.  

Rather than forcing every satellite to carry increasingly large solar arrays and batteries, spacecraft could draw power from a shared orbital network whenever they need it. If successful, this infrastructure could become as fundamental to the space economy as the electrical grid is on Earth.  
Investors are taking notice. Star Catcher has raised approximately $88 million to date, including a recent $65 million Series A led by B Capital, Shield Capital, and Cerberus Ventures. Andrew believes SpaceX's reusable rockets have dramatically reduced the cost of reaching orbit, unleashing an explosion in satellite deployment. The next major bottleneck, however, is no longer launch—it's power. Star Catcher aims to build the energy infrastructure that enables the next generation of space-based industries.  

In this conversation, we explore what's real, what's possible, and what's still myth when it comes to energy in space. We also discuss why technologies that once seemed decades away may arrive much sooner than most people expect.   The future of the space economy isn't just about getting to orbit—it's about powering everything that comes next.  

Live long and prosper.
