Coal plant waste helps build environmentally-friendly, cementless concrete
Concrete production is one of the largest sources of carbon dioxide emissions in the world, after transportation and energy. To make the ubiquitous building material more environmentally friendly, the industry has been adding by-products from coal-fired power plants, but doing so had its own Read More...
Cost plunges for capturing carbon dioxide from the air
Pulling carbon dioxide (CO2) from the air and using it to make synthetic fuel seems like the ultimate solution to climate change: Instead of adding ever more CO2 to the air from fossil fuels, we can simply recycle the same CO2 molecules over and over. But such technology is expensive—about $600 Read More...
This power plant produces energy without emissions. Here’s why that’s a big deal
In 2016, we caught wind of a natural gas power plant being constructed in Texas that claimed it would produce energy without emissions. It promised to capture its own carbon dioxide emissions, not in a separate, expensive, power-intensive process like conventional carbon-capture facilities, but as Read More...
Developers made a bold deal when designing Unilever’s ultra-sustainable HQ
To help reach its goal of being carbon-positive in all operations by 2030, consumer product giant Unilever has transformed its old US headquarters into an ultra-sustainable office park fitted with the latest technology. Throughout the building, 15,000 sensors measure temperature, light, carbon Read More...
A game-changing carbon-capture power plant just passed its first big test
Net Power announced today that it successfully fired up a pilot plant near Houston that takes an entirely new approach to capturing carbon dioxide. The news marks a critical first test for a system that promises an economical path to cutting greenhouse-gas Read More...
Offsetting your emissions can be as simple as adding a penny to your purchases
The emissions from a scoop of ice cream—including everything from the cows to transportation and freezing the product—add up to roughly a quarter of a pound of carbon dioxide. Now if you buy ice cream from a Ben & Jerry’s store in London’s Soho neighborhood, the company will spend a Read More...
Bio-inspired membrane captures 90 percent of CO2 in power plant emissions
Researchers at Sandia National Laboratories have developed a new biologically inspired membrane that can capture carbon dioxide from power plant smoke. Sandia fellow and University of New Mexico regents’ professor Jeff Brinker said, “Our inexpensive method follows nature’s lead in our Read More...
Carbon capture technology may finally take off via the corn industry
Carbon capture and storage (CCS) technology is widely believed to be necessary to save the climate, but the technology is still in a fledgling state, with relatively few large-scale installations around the world. But fitting corn-ethanol refineries with carbon-storing technologies would be a Read More...
China’s massive investment into the environment is paying for itself
China has invested billions and billions into cutting its own greenhouse gas emissions in the last few years. A new MIT study shows the country stands to benefit from this not just environmentally, but financially as well. According to the study, China will net around $339 billion in health savings Read More...
The search for renewable energy storage just had a vital breakthrough
If we want to reduce carbon-dioxide emissions, we have to become smarter about the way we store the energy we make from renewable sources. Our current batteries aren’t capable of storing mass quantities of energy that can be used on-demand, but that may soon change thanks to an incredible Read More...
