Novel “artificial leaf” design ups the carbon capture rate by 100x

Recreating the process of natural photosynthesis in which plants turn sunlight, water and carbon dioxide into energy is a long-pursued goal in science. Often described as an “artificial leaf,” these systems could play a key role in the fight against cl… Continue reading Novel “artificial leaf” design ups the carbon capture rate by 100x

New source of potent greenhouse gas emissions identified in permafrost

It may not be the headline star of the climate change discussion, but nitrous oxide (N2O) is still a potent greenhouse gas – and now it looks like we may have underestimated how much is being released. A new study has identified the thawing Siberian pe… Continue reading New source of potent greenhouse gas emissions identified in permafrost

Squirrel-cheeked liquid H2 airliner will take you anywhere in two hops

Long-haul aviation presents a tough challenge for decarbonization, but a group of 100 aerospace experts working on the UK government’s FlyZero project says 279-seat liquid hydrogen airliners will connect any two points on the globe with just one stop.C… Continue reading Squirrel-cheeked liquid H2 airliner will take you anywhere in two hops

“Earth’s Black Box” to chronicle humanity’s descent into climate chaos

That humankind is on a collision course with a climate reality that poses serious threats to our wellbeing is clear enough, but there is some uncertainty around what happens exactly between now and then. An indestructible “black box” for the Earth is s… Continue reading “Earth’s Black Box” to chronicle humanity’s descent into climate chaos

Campaign to drill for the oldest continuous Antarctic ice core begins

To learn more about the Earth’s climate and environmental history, a research team has begun an €11-million (US$12.9-million) project with the hopes of collecting the oldest continuous ice core in Antarctica, providing a record of the climate spanning … Continue reading Campaign to drill for the oldest continuous Antarctic ice core begins

FuelPositive promises green ammonia at 60% the cost of today’s gray

Canada’s FuelPositive says each of its modular, container-sized ammonia production units will deliver 100 tonnes of green ammonia a year at costs around US$444/tonne, compared to average gray (fossil-fuel-based) ammonia prices that have averaged around… Continue reading FuelPositive promises green ammonia at 60% the cost of today’s gray

The case for converting diesel trains to run on boxcar batteries

Locomotives remain a fast and efficient way to move cargo overland. The low rolling resistance of steel-on-steel will always beat rubber on road, the ability to pull long chains of freight cars, linked closely together, gives trains a significant aerod… Continue reading The case for converting diesel trains to run on boxcar batteries

Earth’s troposphere is expanding due to climate change

A new study has revealed yet another way that human-induced climate change is affecting the planet. Decades of weather balloon and satellite data has shown that the Earth’s troposphere is expanding, even after natural variations are accounted for.Conti… Continue reading Earth’s troposphere is expanding due to climate change

US outlines vision for cheap, large-scale carbon capture technology

Preventing global warming from reaching dangerous levels will require dramatic steps to reduce the amount of carbon dioxide pouring into the atmosphere, but many see removing and safely storing what is already there as another critical part of the solu… Continue reading US outlines vision for cheap, large-scale carbon capture technology

Super-efficient linear compressor could vastly reduce air con power use

Compressor efficiency might not sound like the most exciting topic in the world, but consider this: the hotter the world gets – and the wealthier its developing countries become – the more air conditioners will come online. According to the IEA, fans a… Continue reading Super-efficient linear compressor could vastly reduce air con power use
