Hydrogen-powered vehicles are back in the headlines, with major manufacturers including JCB, Volvo, Mercedes-Benz and Toyota investing in new hydrogen technologies. But while battery-electric vehicle sales continue to grow, hydrogen transport remains stubbornly uncompetitive.

Batteries : Electric vehicle batteries are lasting far longer than many people expected. So when they eventually leave their cars, should we immediately recycle them—or give them a second life storing renewable energy? This week we look at real-world projects in the USA, Canada and Australia, and discover why rapidly falling battery prices, different chemistries and some surprising economics are making that decision far more complicated than it first appears.

Policy : Europe urgently needs more renewable electricity, but grid connection bottlenecks are slowing progress. What if the solution isn't always building more power lines, but making better use of the ones we already have? A new Ember report suggests that Europe's existing hydroelectric plants could accommodate another 25 gigawatts of wind and solar by sharing grid connections.

Policy : China’s new Five-Year Plan sets out an extraordinary expansion of renewable energy, grid infrastructure, storage and resource recycling through to 2030. But with coal still deeply embedded in the country’s energy system, the real question isn’t whether China can hit its new renewable targets — it’s whether this enormous clean-energy expansion will finally begin to push fossil fuels out.

Climate : A Super El Niño is here. We've all heard about it in the news. But what effect will it have on an already rapidly warming Arctic? I ask a proper scientist for some guidance. Help support this channel's independence at

Solar : What if the biggest challenge facing solar power isn’t making the panels cheaper, but finding somewhere to put them? From solar panels between railway tracks in Switzerland to photovoltaic motorway noise barriers in South Korea, engineers are finding increasingly ingenious ways to generate clean electricity from infrastructure we’ve already built — without competing for valuable agricultural land.

Solar: India is entering one of the most energy-intensive periods of economic development in its history — but unlike China, Britain or America before it, much of its new electricity could come from the sun rather than fossil fuels. Solar capacity is soaring, batteries are getting cheaper and renewables are supplying an increasing share of new demand.

Batteries : For years, the battery industry has been obsessed with lithium. But what if we've been asking the wrong question? As sodium-ion batteries move into mass production and costs begin to challenge lithium iron phosphate, the race is no longer about finding one battery to rule them all—it's about choosing the right chemistry for the right job. Could this be the biggest shift in battery technology since the rise of the electric car?

Grid Battery : Switzerland is building one of the world’s largest vanadium redox flow battery installations — a giant underground energy storage system designed to help stabilise the renewable electricity grid. But why choose a huge flow battery instead of the lithium-ion systems now dominating global energy storage?

Solar PV installations hit record levels in 2025. Again. But that growth is now at risk of stalling. So how can that possibly be, and what are governments and commerce doing about it? Help support this channel's independence at

Climate : A new study suggests that warming land masses may be quietly pulling the world's monsoon systems northwards, with profound implications for food production, water security and the lives of billions of people. If the authors are right, this could represent an important missing piece in our understanding of how climate change is reshaping the planet.

Policy : For more than four years, Steve Koonin's book 'Unsettled' has been cited by politicians, commentators and climate sceptics as evidence that the scientific consensus on climate change has been exaggerated. Koonin recently gave a 15 minute summary lecture of his views at the UK 'Alliance for Responsible Citizenship'.

Batteries : For years we’ve been told that China’s dominance in batteries and electric vehicles is mainly down to cheap labour, government subsidies and an uneven playing field. But is that really the whole story? This week we take a closer look at what China’s battery boom can teach us about the future of energy, manufacturing and the global transition away from fossil fuels.

Climate : "It looks like this year’s El Niño is not only very likely to be the strongest event since reliable records began – it may end up the strongest by a truly mind-blowing margin". Those are the words of one of the world's more cautious and conservative climate scientists. So if they're sounding the alarm so strongly - maybe we should sit up and listen!

Climate : There's always a lot of noise whenever we experience a heat wave, isn't there? On one side we hear from doom-mongers who tell us this is a portent of a thoroughly dystopian future that is going to arrive within years. On the other side we have the sceptics who say it's all part of the Earth's natural cycles and we just need to calm down a bit. So, what does the actual science tell us?
