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.
In August, Horizon looks at one of the features that makes Earth unique and habitable: plate tectonics. We explore what we know – and still don’t know – about how the shifting plates beneath our feet shape our planet. We speak to researcher Dr Kate Rychert, who wants to understand what makes a plate plate-like, and delve into one of the outstanding mysteries in the subject – how and why plate tectonics began. We find out about the link between mountain formation, erosion and climate change, and we look at what moonquakes and marsquakes can reveal about tectonic activity elsewhere.
As commutes dropped during coronavirus lockdowns, many of Europe’s city-dwellers breathed cleaner air. In July, Horizon takes a look closer look at our air pollution problem, what it is, how it affects human health and whether now is the time to make the move to greener transport. We spoke to social epidemiologist Dr Basile Chaix about what it will take to capitalise on the post-coronavirus calls for greener cities to really change our urban spaces – and transport habits. We dissect the properties of particulate matter to understand how characteristics such as particle size or number relate to toxicity, and what they do to human cells. With wildfires known to strike particularly in the summer, we look at how scientists are tracking this lesser-known source of air pollution to better understand the impact on human health. And we find out how a soybean-related asthma outbreak in 1980s Spain is influencing air pollution research today.
Eavesdropping on the shudders and groans echoing deep inside alien worlds like Mars and the moon is revealing what lies far beneath their surfaces and could teach us more about how our own planet formed.
More than six months into the coronavirus crisis, data show that not just age, but also biological sex plays a pivotal role in the manifestation and response to Covid-19, with more men dying from acute infections versus women in the short term. This discrepancy has shined a spotlight on a key theme that has gained traction in recent years: is enough being done to account for sex and gender in disease and medicine? Not enough, says Dr Sabine Oertelt-Prigione, the chair of sex and gender-sensitive medicine at Radboud University in the Netherlands and a member of the European Commission’s expert group on gendered innovations.
Earth is not the only place in our solar system that shakes with seismic activity.
