Op IJsland is de grootste installatie ter wereld in gebruik genomen om CO₂ weer uit de atmosfeer te plukken. De machine, die de naam 'Mammoth' meekreeg, moet per jaar 36.000 ton CO₂ uit de lucht halen met een soort gigantisch dampkapsysteem. Hoe werkt het, hoeveel is het klimaat hierbij gebaat en wat zijn de addertjes onder het gras?

Investments of more than half a trillion euros will be needed to modernise Europe's energy grid this decade, if countries are to succeed in ramping up wind and solar power to break free from Russian gas, a draft EU document showed. The European Commission is set to publish next week a plan to "digitalise" Europe's energy system, as well as laying out new emergency measures to tame sky-high gas prices and help cash-strapped energy firms this winter. The draft plan, seen by Reuters, said electricity grid investments of 584 billion euros are needed until 2030, to support the planned rapid uptake of electric vehicles, renewable energy and heat pumps, and shift away from fossil fuels. Of this, around 400 billion euros would target the distribution grid. Some 170 billion of that would focus on ditigalisation, including the so-called "smart grids" that respond faster to local supply and demand fluctuations, helping waste less energy and benefit from cheaper periods.
