Climate change: Most schemes to capture and reuse carbon actually increase emissions

by

Carbon capture and utilisation technologies, which aim to pull carbon dioxide from the air and use it for emissions-lowering processes, emit more carbon than they remove Environment 18 February 2022 By Alex Wilkins A carbon capture facility at the Hawiyah Natural Gas Liquids Recovery Plant in Saudi Arabia Maya Siddiqui/Bloomberg via Getty Images Most carbon … Read more

Engineered bacteria produce chemicals with negative carbon emissions

by

Bacteria have been modified to produce chemicals found in paint remover and hand sanitiser from carbon dioxide in the air, meaning they have negative emissions compared with traditional industrial methods Environment 21 February 2022 By Chen Ly Bacteria can produce a range of chemicals Zoonar GmbH / Alamy Bacteria engineered to turn carbon dioxide into … Read more

The race is on to tackle climate change by pulling carbon from the air

by

By Adam Vaughan Energy firm Drax has a biomass power plant in Yorkshire, UK Clare Jackson/Alamy A CATTLE shed near Edinburgh sucking up methane emissions and a team altering the acidity of seawater in the English Channel might seem unlikely prospects for avoiding increasingly dangerous climate change. But they are just two of 24 projects taking part … Read more

Professional Sports Leagues Need to Reduce Their Carbon Footprint

by

North American sports leagues have at best an inconsistent track record on sustainability; while they all offer some mix of elementary school environmentalism (tree planting, recycling, and preventing food waste), most bask in luxury on board hyperpolluting private planes traveling across the world. This behavior sends a mixed message. Emissions from air travel are the … Read more

The Iron of Earth’s Inner Core Could Be in a Strange ‘Superionic’ State, Study Finds

by

Deep below the crust of Earth, past the thick mantle and liquid outer core, lies a 1,220-kilometer (760 mile) ball of solid inner core. But a new study has suggested that the inner core is not solid at all, instead forming a ‘superionic state’ with hydrogen, oxygen, and carbon, making it unlike either a liquid … Read more

Newly Invented Catalyst Dramatically Increases The Efficiency of Turning CO2 Into Fuel

by

It took nature decades of photosynthesis, followed by eons of intense heat and pressure from geological activity to bake atmospheric carbon dioxide into the long chains of hydrocarbon that make up fossil fuels.   We don’t have the luxury of millions of years to mop up the excess carbon from our atmosphere, but advances in … Read more

‘Killer Lake’ in Africa Looks Like Paradise, But It’s Hiding a Deadly Secret

by

The engineers aboard the floating power station on Lake Kivu could only watch nervously as the volcano in the distance erupted violently, sending tremors rumbling through the water beneath them.   It was not the lava shooting from Mount Nyiragongo last May that spooked them, but the enormous concentrations of potentially explosive gases within Kivu, … Read more
