Capturing carbon

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.

Storing CO2 underground can curb carbon emissions, but is it safe?

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.

Waste CO2 to be turned into ingredients for fuel, plastics and even food

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.

System to rid space station of astronaut exhalations inspires Earth-based CO2 removal

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?

Through a project called CEMCAP, Kristin Jordal and her colleagues found that when it comes to cement production, 90% carbon capture is a realistic target. Image credit - Kristin Jordal

To slash emissions, industries must capture carbon and store it

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.

Organic electronics

In November, Horizon discovers a futuristic world of transparent e-books, plastic solar cells and electronic skin with a look at some of the applications of organic electronics. We speak to organic chemist Prof. Andreas Hirsch about how using carbon rather than silicon in electronics can make them flexible, lightweight and biocompatible and could lead to a new generation of human-looking robots and ‘chemical’ computing. We take a look at work to create electronic skin – self-healing, stretchable material that can mimic some of the functions of human skin – and its potential uses. We discover how thin, flexible, plastic solar cells could turn surfaces such as cars and fabric into sources of renewable energy, and we uncover some novel approaches to charging wearable electronics.

Taking stock: Where next for research?

The world looks very different from this time last year. The coronavirus pandemic has highlighted the centrality of science, research and innovation, accelerated some changes already in the works, but also exposed our weaknesses. In September, Horizon looks at how the pandemic is reshaping Europe in areas including health research, work, tech, transport and food – and how research can contribute to Europe’s recovery over the coming years. We will also be covering the European Research & Innovation Days at the end of the month, which will bring together scientists, policymakers, entrepreneurs and citizens to debate how research and innovation can ensure that the transition to a post-coronavirus society is sustainable, inclusive and resilient.

Electronic skin patches could restore lost sensation and detect disease

Picture this: You’ve experienced no physical sensation beyond your wrists for years, then a doctor drapes a thin, flexible membrane over your hand and, like magic, you can feel the trickle of water through your fingers again.

Five things you need to know about bats, disease and coronavirus

Bats are in the limelight these days because they are rumoured to be the source of SARS-CoV-2, the virus that caused the coronavirus pandemic. But that is just part of their story. Bats turn out to be miraculous creatures. Their ability to age without decrepitude or cancer, as well as fight off a multitude of infections, are giving us clues about how to do the same for ourselves.
