The biggest market for hydrogen as a clean fuel may not be cars—but homes
As in other countries, many people in the UK heat their homes with natural gas, which burns cleaner than oil or coal and thus has been the go-to fuel. In recent years, it has accounted for more than 80% of all the energy consumed on a winter day in Britain, for heat, electricity, and Read More...
Lego invests $155 million in developing bioplastics to make its toys sustainable
Lego has set the target to replace 20 types of conventional plastics used in making its bricks with sustainable materials by 2030 to help curb the company’s total carbon dioxide emissions. The Denmark-based toy maker has invested $155 million into a Sustainable Materials Center, where materials Read More...
Caltech scientists speed up carbon sequestration process by 500 times
Carbon sequestration, or removing carbon dioxide from the atmosphere and storing it long-term, could help us fight climate change. It’s a complex chemical reaction, but a team of six scientists led by the California Institute of Technology (Caltech) just made a breakthrough in speeding up a slow Read More...
Key to speeding up carbon sequestration discovered
Scientists at Caltech and USC have discovered a way to speed up the slow part of the chemical reaction that ultimately helps the earth to safely lock away, or sequester, carbon dioxide into the ocean. Simply adding a common enzyme to the mix, the researchers have found, can make that rate-limiting Read More...
Indian Railways fights air pollution with first train with solar-powered coaches
To reduce the air pollution that has become a plague in many cities in India, the Indian Railways has introduced their first train outfitted with rooftop solar panels. The solar panels will completely power fans, lighting, and display systems in the coaches. In the past, a diesel-fueled generator Read More...
Will future office buildings harvest algae in their lobbies?
In a prototype of an urban algae farm now on display in an exhibition in Kazakhstan, shows how algae could fit inside existing buildings where people live and work. Designers suspended coils of lightweight glass tubes from the ceiling, attached to pumps that visitors can press to send carbon Read More...
Sweden uses revolutionary cement technology to get to zero emissions
Sweden has committed to reaching net-zero emissions of greenhouse gases by 2045. Today, only 5 percent of the electricity Swedes consume comes from burning fossil fuels. Still, the country has big challenges to overcome to meet the ambitious goal. Here’s one innovative solution Sweden is Read More...
To curb climate change, we need to protect and expand US forests
Forests have been removing carbon dioxide from the atmosphere and storing carbon for more than 300 million years. When we cut down or burn trees and disturb forest soils, we release that stored carbon to the atmosphere. Since the start of the Industrial Revolution, one-third of all carbon dioxide Read More...
Cheap catalysts turn sunlight and carbon dioxide into fuel
Scientists have long dreamed of mimicking photosynthesis, by using the energy in sunlight to knit together hydrocarbon fuels from carbon dioxide and water. Now, a cheap new chemical catalyst has carried out part of that process with record efficiency, using electricity from a solar cell to split Read More...
Australia set to use hydrogen to export its solar power around the world
The future of hydrogen is bright. Since it doesn’t emit carbon dioxide when its burned, hydrogen is potentially the ultimate source of clean energy. And thanks to recent innovations, we now have the ability to produce hydrogen more efficiently, use it to store other clean energy, and even Read More...
