NREL Selected for Space-Bound Research To Solve the Plastic Waste Dilemma

Researchers at the National Renewable Energy Laboratory (NREL) will send an engineered bacteria into space as early as next year as part of ongoing research into solving the problem of plastic waste mitigation on Earth.

Deconstructed plastics, using the NREL oxidation platform, will be flown to the International Space Station (ISS), where astronauts will conduct an experiment involving bacteria engineered to upcycle oxidized plastic. The Center for the Advancement of Science in Space (CASIS) selected the NREL project as part of the ISS National Laboratory Sustainability Challenge: Beyond Plastics. The beauty brand Estée Lauder is providing financial backing for the challenge, with costs going to ISS National Laboratory partner Rhodium Scientific to provide engineering and flight support.

Project would make jet fuel using concentrated solar power and green hydrogen

A demonstration project in California plans to use concentrated solar power and green hydrogen to produce what its development partners said would be sustainable aviation fuels.

The project will take place at concentrated solar power (CSP) provider Heliogen's demonstration facility in Lancaster in northern Los Angeles County. Heliogen is partnering with sustainable aviation fuels (SAF) firm Dimensional Energy on the project.

The first fully hydrogen-powered passenger train service is now running in Germany

The first fully hydrogen-powered passenger train service is now up and running. Coradia iLint trains built by Alstom are running on the line in Lower Saxony, Germany. The only emissions are steam and condensed water, and Alstom notes that the train operates with a low level of noise.

Five of the trains started running this week. Another nine will be added in the coming months to replace 15 diesel trains on the regional route. Alstom says the Coradia iLint has a range of 1,000 kilometers, meaning that it can run all day on the line using a single tank of hydrogen. A hydrogen filling station has been set up on the route between Cuxhaven, Bremerhaven, Bremervörde and Buxtehude.

Say Goodbye to Sprite's Green Bottles

(NEWSER) – Sprite's green plastic bottles will soon be a thing of the past. Coca-Cola says it's changing the packaging of Sprite and other beverages, including Fresca, to clear plastic so it can step up recycling, CNN reports. The green polyethylene terephthalate—PET—currently used in Sprite bottles can be recycled, but unlike clear PET, it can't be made into new bottles, reports CBS. The company says it has also revamped the Sprite logo to provide a "consistent look and voice around the world," but the label will remain green.
