Hydrogen Production via Methane Pyrolysis: An Overview of ‘Turquoise’ Hydrogen

‘Turquoise’ hydrogen processes generate H2 without releasing CO2. Presented here are the opportunities and challenges for producing hydrogen by methane pyrolysis Hydrogen-producing processes are classified using a color scheme according to their carbon footprint (Table 1; [1–3]). So-called “turquoise hydrogen”…

Unipar modernizes chlor-alkali plant in Brazil with thyssenkrupp nucera technology

Unipar (São Paulo, Brazil) is modernizing its chlor-alkali plant at the Cubatão plant in Brazil by incorporating electrolyzers from thyssenkrupp nucera AG & Co. KGaA (Dortmund, Germany; ). To modernize the plant, the Brazilian chemical company, a leader in the…

Taking graphene into the next dimension

Graphene has been touted as a “super” material, boasting ultra-high strength, superconductivity and many more superlative properties, but, as a planar two-dimensional material, its commercial use has been limited in terms of reactivity, since reactions can only occur at the…

Immobilizing enzymes as a stable, active foam

Researchers at the Karlsruhe Institute of Technology (KIT; Germany; www.kit.edu) have developed a new class of materials — enzyme foams. Normally, foaming modifies the enzyme structure and enzymes lose their biocatalytic activity. The new protein foams, however, are said to…
