New polymer membrane efficiently removes carbon dioxide from mixed gases; high permeability and selectivity

Green Car Congress

A team of researchers from North Carolina State University, SINTEF in Norway and the Norwegian University of Science and Technology, has developed a polymer membrane technology that removes carbon dioxide from mixed gases with both high permeability and high selectivity. the ability to separate one gas from another.

Water covers 72 percent of the Earth’s surface, its volumes host 80 percent of biodiversity and play a pivotal role in global phenomena, such as climate change. and Norway. We can allow teams of robots to communicate and collaborate, to send data, get instructions, and change their mission in real time.”

This question of whether climate change becomes so bad that we have to do something to dull its impacts and reduce human suffering is a very big one,” says Keutsch, an atmospheric chemist. Critics say that pursuing the technology is a dangerous distraction from the more essential task of rapidly reducing greenhouse gas emissions.

CICERO-led study finds global warming effect of leaked hydrogen almost 12x stronger than CO2

Green Car Congress

Unlike exhaust from burning coal and gas that contains CO 2 , burning hydrogen emits only water vapor and oxygen. Hydrogen is not a greenhouse gas, but its chemical reactions in the atmosphere affect greenhouse gases such as methane, ozone, and stratospheric water vapor. Sand et al.

Big Auto is begging governments to let them go bankrupt as Chinese EVs loom

Baua Electric

Automakers are fiercely lobbying governments to water down already-compromised emissions rules, but doing so will only lead to their doom as market entrants that are serious about EVs will continue ramping them anyway. But most automakers still only have a few EVs, and many of them still share platforms with gas cars.

Naysayer Alert – the hydrogen red herring

My Electric Car

The energy stored within hydrogen has been imparted from electrical energy through the electrolytic hydrogen production process or more likely in the refinement of fossil fuels such as coal seam (methane) gas – both are energy intensive processes in themselves. . The reasons are numerous. .

Stanford study finds energy requirements of super-giant oilfields can significantly increase over time

Green Car Congress

Mohammad Masnadi and Adam Brandt used decades-long time-series data from twenty-five globally significant oil fields (>1 billion barrels ultimate recovery) to model greenhouse gas (GHG) emissions from oil production as a function of time.Depletion requires increased energy expenditures in drilling, oil recovery, and oil processing.
