Finnish demo plant produces renewable fuel from carbon dioxide captured from the air

The unique Soletair demo plant developed by VTT Technical Research Centre of Finland and Lappeenranta University of Technology (LUT) uses carbon dioxide to produce renewable fuels and chemicals. The pilot plant is coupled to LUT's solar power plant in Lappeenranta.

The aim of the project is to demonstrate the technical performance of the overall process and produce 200 litres of fuels and other hydrocarbons for research purposes. This concerns a one-of-a-kind demo plant in which the entire process chain, from solar power generation to hydrocarbon production, is in the same place.

As Alaska's North Slope warms, greenhouse gases have nowhere to go but up

The amount of carbon dioxide (CO2) being released from tundra in the northern region of Alaska during early winter has increased 70 percent since 1975, according to a new regional climate paper by scientists participating in a research project funded by NOAA and NASA.

Iqaluit could start running out of fresh water by 2024

Without action, the supply of fresh water in Iqaluit will begin to dwindle by 2024 due to climate change and increased demand, research led by York University has found. 

“Extreme climates make the management of fresh water difficult, but add climate change to the mix, along with too few financial and human resources, and northern cities, such as Iqaluit could run out of fresh water,” said Andrew Medeiros of York University who led the research.

China's Air Pollution Sharply Limits CO2 Uptake by Plants on Large Scale, Study Shows

The exceptionally high levels of surface ozone, aerosol particles, and other air pollutants in China are damaging plants and interfering with their ability to absorb carbon dioxide, according to a new study.

Researchers at the University of Exeter in the UK said that elevated levels of these pollutants in many parts of China are oxidizing plant cells and weakening the process of leaf photosynthesis and CO2 uptake. The impact of the ozone damage is so widespread that it actually has an effect on the regional carbon balance and impedes efforts to reduce planet-warming greenhouse gases, according to the study, published in the journal Atmospheric Chemistry and Physics.

Musk Says Tesla Plans to Build up to 20 'Gigafactories' Worldwide

At Tesla’s annual shareholder meeting, founder and CEO Elon Musk said the company eventually plans to build 10 to 20 “gigafactories” capable of producing both cars and lithium-ion batteries.

At Tesla’s annual shareholderTesla — now in the business of making electric vehicles, batteries, and solar panels — is currently building its first gigafactoryoutside of Sparks, Nevada. That plant, which will be more than three times the size of New York City’s Central Park, will begin battery production this year. In 2018, the factory is expected to produce more lithium-ion batteries annually than were produced globally in 2013. The Nevada gigafactory is currently devoted to producing only batteries.

Rubber Algae Help Create Artificial Reef; Could Combat Ocean Acidification

A team of European researchers is testing whether tiny artificial algae can help protect coral reefs in the Mediterranean Sea that are threatened by ocean acidification due to climate change. 

The small plastic structures are made of a non-toxic, highly elastic rubber, and are designed to mimic natural coralline algae. Like coral, coralline algae help form reef habitats for small invertebrates.

Lab on a Chip Could Monitor Health, Germs and Pollutants

Imagine wearing a device that continuously analyzes your sweat or blood for different types of biomarkers, such as proteins that show you may have breast cancer or lung cancer

Rutgers engineers have invented biosensor technology – known as a lab on a chip – that could be used in hand-held or wearable devices to monitor your health and exposure to dangerous bacteria, viruses and pollutants.

“This is really important in the context of personalized medicine or personalized health monitoring,” said Mehdi Javanmard, an assistant professor in the Department of Electrical and Computer Engineering at Rutgers University-New Brunswick. “Our technology enables true labs on chips. We’re talking about platforms the size of a USB flash drive or something that can be integrated onto an Apple Watch, for example, or a Fitbit.”

Researchers Find a Surprise Just Beneath the Surface in Carbon Dioxide Experiment

In a classic tale of science taking twists and turns before coming to a conclusion, two teams of researchers—one a group of theorists and the other, experimentalists—have worked together to solve a chemical puzzle that may one day lead to cleaner air and renewable fuel. The scientists' ultimate goal is to convert harmful carbon dioxide (CO2) in the atmosphere into beneficial liquid fuel. Currently, it is possible to make fuels out of CO2—plants do it all the time—but researchers are still trying to crack the problem of artificially producing the fuels at large enough scales to be useful.

In a new study published the week of June 12 in the journal Proceedings of the National Academy of Sciences (PNAS), researchers report the mechanics behind an early key step in artificially activating CO2 so that it can rearrange itself to become the liquid fuel ethanol. Theorists at Caltech used quantum mechanics to predict what was happening at atomic scales, while experimentalists at the Department of Energy's (DOE) Lawrence Berkeley National Lab (Berkeley Lab) used X-ray studies to analyze the steps of the chemical reaction.

Peatlands, already dwindling, could face further losses

Tropical peat swamp forests, which once occupied large swaths of Southeast Asia and other areas, provided a significant “sink” that helped remove carbon dioxide from the atmosphere. But such forests have been disappearing fast due to clear-cutting and drainage projects making way for plantations. Now, research shows peatlands face another threat, as climate change alters rainfall patterns, potentially destroying even forested peatlands that remain undrained.

The net result is that these former carbon sinks, which have taken greenhouse gases out of the atmosphere, are now net carbon sources, instead accelerating the planet’s warming.

U.S. had 8th warmest, 11th wettest spring on record

The month of May typically signals both an ending and a beginning: The waning days of spring and then the time-honored leap into summer vacation season.

Before we throw on our bathing suits and flip flops, let’s first take a look back at how last month, spring and the year to date fared in terms of the climate record ...
