Raven SR & Hyzon Motors to build up to 100 waste-to-hydrogen hubs

Green Car Congress

At the hubs, which can be built at or near landfills, Raven SR will convert mixed and multiple organic wastes, including municipal solid waste, greenwaste, food waste, medical, paper, etc. This permits the control of the rotary reformer when there is water content or chemical makeup variation in the feedstock, such as in MSW.

NTNU researchers use reverse electrodialysis and waste heat for hydrogen production: Heat to H2

Green Car Congress

A new approach developed by researchers at the Norwegian University of Science and Technology (NTNU) could alleviate that situation a bit by using waste heat from other industrial processes. Energy experts say that the waste heat from Norway’s businesses and industries is the equivalent of 20 TWh of energy. —Krakhella et al.

OSU team develops process to clean coal mine drainage and extract rare earth elements

Green Car Congress

The TEP process uses the alkalinity and filtering capacity of stabilized flue gas desulfurization (sFGD) material or water treatment plant (WTP) sludge to remediate CMD waters and extract REEs. One thing that surprised me was just how well our process cleans up the water. CMD, coal mine drainage; TEP, trap-extract-precipitate.
