Scientists Develop Technology That Burns Natural Gas With No CO2 Emissions

New submitter Ben Sullivan writes: Researchers and engineers in Vienna have developed a way to burn natural gas without releasing CO2 into the air through a combustion method called chemical looping combustion (CLC). In this process, CO2 can be isolated during combustion without having to use any additional energy, which means it can then go on to be stored. The method had already been applied successfully in a test environment, and has now been upscaled to allow use in up to a 10 MW facility. ScienceBlog.com reports: "A granulate made of metal oxide circulates between the two chambers and is responsible for transporting oxygen from air to fuel: 'We pump air through one chamber, where the particles take up oxygen. They then move on to the second chamber, which has natural gas flowing through it. Here is where the oxygen is released, and then where flameless combustion takes place, producing CO2 and water vapor,' explains Stefan Penthor from the Institute of Chemical Engineering at TU Wien. The separation into two chambers means there are two separate flue gas streams to deal with too: air with a reduced concentration of oxygen is discharged from one chamber, water vapor and CO2 from the other. The water vapor can be separated quite easily, leaving almost pure CO2, which can be stored or used in other technical applications."

Juno Spacecraft Reveals Spectacular Cyclones At Jupiter's Poles

Joe Palca reports via NPR: NASA's Juno spacecraft has spotted giant cyclones swirling at Jupiter's north and south poles. That's just one of the unexpected and puzzling findings being reported by the Juno science team. Juno arrived at Jupiter last summer. It's the first spacecraft to get a close-up look at the planet's poles. It's in an orbit that takes it skimming close to the cloud tops of the gas giant once every 53 days. After each close pass, the spacecraft sends a trove of data back to Earth. Ultimately, scientists will want to understand how these cyclones change over time and whether they form differently in the north and south poles. Another puzzle that Juno is supposed to help solve is whether Jupiter, a gas giant, has a solid core. Another surprise from Juno is the concentration of ammonia in Jupiter's atmosphere. Scientists thought ammonia was most likely distributed evenly throughout the atmosphere. The data show there's more ammonia near the equator than there is at other latitudes.

Chinese Company Offers Free Training For US Coal Miners To Become Wind Farmers

An anonymous reader quotes a report from Quartz: If you want to truly understand what's happening in the energy industry, the best thing to do is to travel deep into the heart of American coal country, to Carbon County, Wyoming (yes, that's a real place). The state produces most coal in the US, and Carbon County has long been known (and was named) for its extensive coal deposits. But the state's mines have been shuttering over the past few years, causing hundreds of people to lose their jobs in 2016 alone. Now, these coal miners are finding hope, offered from an unlikely place: a Chinese wind-turbine maker wants to retrain these American workers to become wind-farm technicians. It's the perfect metaphor for the massive shift happening in the global energy markets. The news comes from an energy conference in Wyoming, where the American arm of Goldwind, a Chinese wind-turbine manufacturer, announced the free training program. More than a century ago, Carbon County was home to the first coal mine in Wyoming. Soon, it will be the site of a new wind farm with hundreds of Goldwind-supplied turbines.

Municipalities open their GIS systems to citizens

Many public administrations already use open source Geographic Information Systems (GIS) to let citizens look at public geographic data trough dedicated Web sites. Others use the same software to partially open the data gathering process: they let citizens directly add geographic information to the official, high-quality GIS databases by drawing or clicking on digital maps.
