Toyota and DIFFER partner on direct solar production of hydrogen from humid air, rather than water

Green Car Congress

The Dutch Institute for Fundamental Energy Research ( DIFFER ) is partnering with Toyota Motor Europe (TME) to develop a device that absorbs water vapor, and splits it into hydrogen and oxygen directly using solar energy. New sustainable fuels are needed 1) to decrease dependence on fossil fuels, and 2) to lower the emission of greenhouse gasses. This group had been working on a method to split water in the vapor phase instead of the liquid phase, which is much more common.

Study finds methane emissions from coal mines ~50% higher than previously thought

Green Car Congress

In addition to coal mining, other major sources of methane emissions globally include wetlands, agriculture, and oil and gas facilities. Kholod said that when a closed mine is flooded, water stops methane from leaking almost completely within about seven years. Methane emissions are a constant concern at coal mines, which vent the gas as it is emitted when coal seams are disturbed. The study analyzed future methane emissions from coal mines under a range of scenarios.
