There are different techniques for producing hydrogen. Depending on the process, the hydrogen obtained may be labelled as black, grey, blue, green, etc.... Currently, 95% of the hydrogen consumed worldwide is produced from natural gas or coal.... Green hydrogen can be produced by "water electrolysis, "whereby an electric current is passed through water to break down its molecules... and extract hydrogen. In addition, if the current comes from a renewable energy source(hydroelectricity, wind or solar power), all elements of the generation cycle are low-carbon.  3, record 1, English, - green%20hydrogen

In the oxo process for alcohol manufacture, hydroformylation of olefins to aldehydes is the first step. The second step is the hydrogenation of the aldehydes to alcohols. At times the term "oxo process" is used in reference to the hydroformylation step alone.

Because sulfur dioxide is the main precursor of acidity, and because understanding of the atmospheric behaviour of sulfur is most advance, sulfate and sulfur dioxide, in addition to hydrogen ion, are frequently used as reliable indicators of the acid deposition phenomenon.  1, record 23, English, - atmospheric%20behaviour

In addition to the familiar molecular acids, two classes of ionic acids emerge from the new definition [Bronsted-Lowry]. The first comprises anions derived from acids containing more than one acidic hydrogen; e. g., the bisulfate ion... derived from phosphoric acid(H3PO4). The second... consists of positively charged ions(cations), such as the ammonium ion...  1, record 25, English, - acidic%20hydrogen
