Can nuclear fusion save the planet?Seen as the ‘holy grail’ of clean energy, scientists are racing to turn a century of experiments into a viable source of powerHow next-gen solar panels could go on lampposts, cars and even windows Perovskite panels are more powerful, lighter and less rigid than traditional alternativesWhy aircraft contrails are as bad for the climate as their CO₂ emissionsThe condensation trails can trap heat in the atmosphere, creating a ‘double whammy’ global warming effectHow growing rice differently could ease climate changeWaterlogged paddy fields produce a lot of methane, but alternative techniques existCan rapid-charging EVs eliminate ‘range anxiety’?Two models from China’s BYD promise to add 250 miles of charge in five minutesMoving beyond ‘plant bait for the vegans’: can meat substitutes convince consumers?Shifting diets could cut emissions — if shoppers can be persuadedMore from this SeriesHow geothermal energy could provide ‘always on’ supplyInterest is growing in fracking techniques pioneered by the oil and gas industry for use in tapping the earth’s crust for powerHow spreading rocks on fields could combat climate change‘Enhanced rock weathering’ is a simple, but also hard to measure, way of capturing carbonClimate tech explained: low-emission steel plantsThere are alternatives to highly polluting blast furnaces, but they require vast quantities of green electricityClimate tech explained: grid-scale battery storageEnergy storage at a scale to power whole towns or cities is an essential part of the transition to net zeroClimate tech explained: methane inhibitorsReducing the amount of gas produced by cows can cut overall emissions from farmingClimate tech explained: direct air captureSucking carbon straight from the air could play a role in reaching net zero, provided costs come downClimate tech explained: carbon capture and removalThere’s no shortage of techniques — only a lack of consensus over pros and consClimate tech explained: sustainable aviation fuelsAircraft travel is perhaps the hardest human activity to decarbonise. Used cooking oil is part of the solutionClimate tech explained: heat pumpsBest understood as operating like a fridge in reverse, the technology is a key part of the road to net zeroClimate tech explained: fertiliser Making crop nutrients requires a lot of fossil fuels — using hydrogen instead could put an end to that
