The optimized photo-electrochemical water splitting device uses light absorbers made of silicon arranged in closely packed pillars, dotted with tiny clusters of the new molybdenum sulfide catalyst. An alternative, clean method is to make hydrogen fuel from sunlight and water via a photo-electrochemical (PEC, or water-splitting) process.
In working to elucidate the chemistry of hydrodeoxygenation (HDO) for the catalytic upgrading of pyrolytic bio-oil to fuel-grade products, researchers at Pacific Northwest National Laboratory (PNNL) have discovered that water in the conversion process helps form an impurity which, in turn, slows down key chemical reactions.

The study also provides fundamental insights into the nature of cellulose recalcitrance. Most thermochemical pretreatments fall within the first category (e.g.,
To address this, we have developed models for metal nanostructures and oxygen, water and metal interactions that exceed the accuracy of current quantum methods by more than 10 times. These interactions make the difference between a slow or fast follow-on reaction and need to be controlled for the process to work efficiently.

Methanization works by producing methane (CH 4 ) and water (H 2 O) by catalytic conversion from carbon dioxide (CO 2 ) and hydrogen (H 2 ). Water causes problems with conventional processes, however; to remove it, serial methanization stages are typically required—with condensation areas in between. Schröter K.,

The two main components—the electrochemical conversion hardware through which the fluids are flowed (which sets the peak power capacity) and the chemical storage tanks (which set the energy capacity)—may be independently sized. The quinones are dissolved in water, which prevents them from catching fire.

The final design is a 1.2-meter-high
The dry reforming process differs from steam reforming, which combines CH 4 and water (H 2 O) in the form of steam to produce the syngas. Producing the steam is energy-intensive; dry reforming requires far less water, and hence avoids the energy burden of steam production. Christian Bruch, Member of the Executive Board of Linde AG.
