| Résumé : |
The generation of energy, and sources of energy that tanneries can use, is increasing. With many material sustainability indices now requiring details on energy use and generation, and specifically to increase the renewable component of the energy used, the pressure is on for tanneries to be more transparent about their energy mix.
Most tanneries have opted for using huge arrays of photovoltaic (PV) cells that can pre-heat water prior to heating in boliers, or to gain energy for use in the facility. Combinations of new generation photocells that can harvest energy in low light levels, at acute angles, or that can be stored in analogue (e.g. pumping water up hills for recapture by hydroelectric gravity microgenerators later) or in battery banks are being seen. |

- Hydrogen sources
- Fig. 1 : Generation of hydrogen from electrolytic splitting of water into oxygen and hydrogen - called green hydrogen
- Fig. 2 : Generation of hydrogen from electrolytic splitting of water into oxygen and hydrogen - called yellow hydrogen (if from photovoltaic cells), or pink, purple, or red hydrogen from nuclear sources
- Fig. 3 : Generation of hydrogen from gasification of waste or brown coal (brown hydrogen), or from black or typical fossil fuel sources (black hydrogen)
- Fig. 4 : Generation of hydrogen from steam reforming and natural gas or methane, with carbon (CO2) capture (blue hydrogen) or carbon (solid) capture (turquoise hydrogen), or without carbon capture (grey hydrogen) |
