In its landmark report in October, the UN's International Panel on Climate Change said that every package of measures we choose to limit global temperature rises to 1.5°C must include a way of removing carbon dioxide emissions from the air and reusing or storing them. This month, Horizon looks at what's being done to advance these carbon capture, storage and utilisation technologies. We talk to one expert who is trying to trap emissions from the cement industry before they are released, and find out how International Space Station technology is inspiring the capture of ambient carbon dioxide. We also investigate how captured CO2 can be reused, and examine just how safe it is to store the gas underground.
At first glance, it almost sounds crazy. Can we really take carbon dioxide emissions from an industrial plant and store them underground? To find out, research is currently taking place to test if such an idea is not only viable but safe, and prove that to the public.
Scientists are ramping up efforts to turn waste CO2 from industry into chemicals such as methanol in a bid to reduce emissions and provide a new source of raw materials for use in fuel, cement and food production.
When astronauts aboard the International Space Station (ISS) exhale carbon dioxide (CO2), it’s removed from the air and pumped into space. Could an Earth-based version help remove greenhouse gas emissions from our atmosphere?
The technology to help limit global warming to 1.5˚C already exists, but there needs to be the will to use it, according to Kristin Jordal, an engineer and senior research scientist at the Norwegian research organisation Sintef.
By 2050, the world's population will be an estimated 9.7bn people, up from today’s 7.7bn. To feed this growing population whilst also protecting the climate and biodiversity, our food system needs to change dramatically. In May, we look at what sort of future food system we want and how to get there. We speak to sustainability expert Prof. Peter Jackson about how lockdowns have exposed our reliance on fragile supply chains, and what needs to happen to shape a more sustainable food system. We look at the smart farming solutions that are being explored to support food producers, and urban experiments from tackling food waste to strengthening organic, local production to see how these efforts can be scaled up to make a big difference. And we investigate insects – a protein-rich food and feed source – and the efforts behind mainstreaming what is still a niche science.
With the world in the grip of the coronavirus pandemic, in April Horizon takes a step back to look at some of the challenges around sudden outbreaks of emerging diseases. We speak to virologist Prof. Marion Koopmans about the likelihood of future outbreaks of new diseases, what causes them and how to spot them before they appear. We speak to scientists who are helping to develop tests for Covid-19 to understand the challenges in coming up with an accurate and detailed diagnostic test for an entirely new disease. We talk to people working on coronavirus treatments about how to shorten the normally lengthy process of drug development. And we look into why diseases suddenly jump from animals, such as bats, into humans and the particular challenges of spotting and responding to these types of outbreaks.
Lithium-sulphur batteries, which are lighter and cheaper than today’s models, may be the next generation of power cells that we use in electric cars or mobile phones – if scientists can get them to last for longer.
We are seeing a failure of global health governance in response to Covid-19 because there are too many agencies with different interests, according Professor Colin McInnes, pro-vice chancellor at Aberystwyth University in Wales, UK, who says global institutions such as the World Health Organization and World Bank should stand together in crises.
The next-generation batteries could pack 5 times more energy, but there are problems.
Prof. Colin McInnes says international organisations are failing to stand together.
Metagenomics can help us spot emerging diseases such as coronavirus, says virologist Marion Koopmans.
