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?

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.

Future gazing

The next decade sees Europe facing some urgent challenges: climate change, biodiversity loss and feeding a growing population, to name but a few. At the same time, technology is developing apace, presenting both opportunities for novel solutions and worries about how to ensure it’s used for good. In September, as plans for the EU’s next research funding programme start to crystallise, we take a look at some of the pressing issues facing Europe and how the next research agenda should be designed to best serve people and planet. We will also be covering the EU’s Research and Innovation Days event at the end of the month, where policymakers, academics, business people and civil society organisations will gather to finalise priorities for Horizon Europe, the EU’s €100 billion research programme which runs from 2021 to 2027.

Sustainable cities

In August, Horizon takes a look at the quest to make Europe’s cities environmentally sustainable, while also ensuring a healthy and prosperous population. We speak to geographer Professor Harriet Bulkeley on why cities have such an important role in fighting climate change, what it means for a city to be sustainable and the big challenges that lie ahead. We look at the construction of zero-energy housing, homing in on the case of Nottingham, UK, and find out how scientists are putting nature back into the old Spanish capital of Valladolid. We also talk to the city officials breathing new life into historical buildings in Bologna, Italy, and learn how urban planners and architects are taking emotional feedback into account when designing new public spaces and homes.

Prosperity is about more than money. But what else should count?

More than two decades ago, Professor Andrew Oswald worked at the London School of Economics, UK, when he organised what he says was the world’s first conference on the economics of happiness. He put up posters, invited speakers, and waited for the crowds to come.

Will we ever cure cancer?

Cancer is a group of diseases that we may never be able to cure completely, but scientists are optimistic that vaccines, personalised medicine and smart lifestyle choices will help prevent and treat a much greater proportion of cases than currently happens.
