Finnish demo plant produces renewable fuel from carbon dioxide captured from the air
June 13, 2017 09:51 AM - Technical Research Centre of Finland (VTT)

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.

Musk Says Tesla Plans to Build up to 20 'Gigafactories' Worldwide
June 12, 2017 05:00 PM - Yale Environment 360

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.

Researchers Find a Surprise Just Beneath the Surface in Carbon Dioxide Experiment
June 12, 2017 04:04 PM - California Institute of Technology

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.

The strength test
June 9, 2017 03:33 PM - Fraunhofer-Gesellschaft

Wind turbines rise into the sky on enormous feet. To ensure these giants can reliably generate electricity for many years to come, the iron processing industry must manufacture their massive components in a stable, resource-saving and yet cost-effective way. However, material inclusions such as dross are often unavoidable while casting. Fraunhofer researchers are currently working to detect and analyze such material defects.

Wind turbines should be environmentally friendly, highly efficient, cost-effective, and able to function reliably for at least 20 years. However, as turbines become increasingly powerful, the demands on the components used are growing, and so is the risk of material fatigue. Material defects such as inclusions from slag, known as dross, are considered undesirable because they greatly reduce the load-bearing capacity of cast iron components with spheroidal graphite. This special kind of cast iron is also used to make a wind turbine’s mainframe and rotor hubs. Manufacturing such components is difficult due to the build-up of dross that often occurs despite tricks in casting techniques.

Researchers Compute Their Way Toward Cleaner Coal Plants

When you think of turbulence, you might think of a bumpy plane ride. Turbulence, however, is far more ubiquitous to our lives than just air travel. Ocean waves, smoke from fire, even noise coming from jet engines or wind turbines are all related to turbulence.

Record 'green' energy capacity added in 2016 as cost for renewables plunges — UN-backed report
June 8, 2017 09:11 AM - UN News Centre

The world is now adding more green energy capacity each year than it adds in new capacity from all fossil fuels combined, a United Nations-backed report revealed today, showing that the “renewables train has already left the station” and those who ignore this will be left behind.
