Environmental research and analysis

A process used to release hydrogen from its bonded state with other elements.

A process developed at Rice University that rapidly heats waste plastic to extremely high temperatures to convert it into graphene and hydrogen gas. The technique grinds plastic into confetti-size pieces, mixes it with a conductive material, and passes very high voltage through the mixture.

An energy-efficient method developed by Nanyang Technological University using light-emitting diodes and a vanadium catalyst to convert plastic waste into hydrogen.

Industrial hydrogen gas produced by Linde for use in fuel stations and hydrogen-powered vehicles.

High-value carbon material produced as the primary output of the flash joule heating process from waste plastic. The article notes it could be sold at current market value or at discounted rates to offset hydrogen production costs.
