The race is on to prove that CO2 can be taken from the air and recycled into profitable, carbon neutral fuels. But cost and investment obstacles remainIn an industrial greenhouse about 30km from Zurich, plump aubergines and juicy cherry tomatoes are ripening to perfection. Growing Mediterranean crops in Switzerland would traditionally be energy intensive but these vegetables are very nearly carbon-neutral. The greenhouse uses waste energy from a nearby refuse plant, and carbon dioxide from the world's first commercial direct air capture plant.The facility, designed by Zurich-based start-up Climeworks, pumps the gas into greenhouses to boost the plants' photosynthesis and increase their yield, it hopes, by up to 20%. Climeworks says it will extract around 900 tonnes of CO2 a year from the air. Continue reading...
