‘Internet of electricity’ and zero-carbon molecules will help decarbonise Europe – report

The EU should cut greenhouse gases by 80% compared to 1990 levels by 2050, according to the European Commission's low-carbon economy roadmap.

An ‘internet of electricity’, zero-carbon cities and turning European soils into carbon sinks are among a slew of ambitious ideas to decarbonise our society and slash greenhouse gas emissions proposed by environmental experts in a reportpublished on 28 November. ‘The message in our report is that this decarbonisation business is potentially a huge economic opportunity,’ said Professor … Read more

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

Scientists at Hellisheidi geothermal power plant in Iceland have demonstrated a carbon capture and storage cycle at half the cost of previous estimates.

by Jonathan O’ Callaghan 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. This approach is … Read more

To slash emissions, industries must capture carbon and store it

Carbon capture and storage is the only way for many industries to significantly reduce emissions, according to Sintef scientist Kristin Jordal.

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. As coordinator of the CEMCAP project, she and her colleagues have been investigating how to reduce greenhouse gas … Read more

A new type of outdoor filter that could cut city air pollution and is scheduled to be debuted at the 2024 Paris Olympics has been awarded the €3 million Horizon Prize on materials for clean air. The prize, which was announced on 30 October at the Innovative Industries for Smart Growth Conference in Vienna, Austria, was … Read more

Scientists want to use dirty nappies as a source of raw materials

The hardest part about recycling used nappies is opening them.

Thousands of soiled nappies that were destined to clog Italian landfill sites or incinerators are being redirected to a recycling plant that is turning them into streams of high quality raw materials, in a new process that it is hoped will be replicated around Europe. Every day, new parents find themselves sucked into the environmentally … Read more

Seaweed-powered trucks – hope or hype?

The infrastructure for turning seaweed into a sustainable alternative for livestock feed, chemicals and energy is still in its infancy.

Seaweed has long been touted for its potential as a sustainable ingredient for biofuels, green chemicals and biodegradable materials, but scaling up production to industrial levels in a way that maintains its environmental credentials is proving a real challenge for scientists. ‘The potential is there, all the data points to it,’ said Dr Jaap van … Read more
