  • Publication number: 20220349525
    Abstract: Apparatus, methods and technologies are described for utilizing a liquid organic hydrogen carrier (LOHC) fueling station to supply fresh or hydrogen laden LOHC and to recover spent or hydrogen depleted LOHC liquid fuels from mobile vehicles and tanker trucks to support the use of LOHC as carbon-neutral hydrogen fuels to power vehicles, to generate and store electricity, to generate and capture hydrogen, and to replace the use of conventional hydrocarbon fuels while maintaining an overall carbon-neutral balance with respect to the environment. The disclosure includes apparatus, methods and technologies to resupply a modular LOHC fueling station, to store, dispense and recover LOHC fuels, and to transfer the LOHC liquid fuels while balancing displaced vapors to maintain an overall carbon-neutral environmental footprint.

  • Patent number: 10941421
    Abstract: The present invention relates to processes for producing ethanol from lignocellulosic hydrolysates comprising, hexoses, pentoses and acetic acid, whereby genetically modified yeast cells are use that comprise an exogenous gene encoding an acetaldehyde dehydrogenase and a bacterial gene encoding an enzyme with NAD+-linked glycerol dehydrogenase activity. The process is further characterised in that glycerol is present in or fed into the culture medium, whereby the modified yeast cell ferments the hexoses, pentoses, acetic acid and glycerol to ethanol. The invention further relates to yeast cells for use in such processes. The yeast cells advantageously comprise genetic modifications that improve glycerol utilization such as modifications that increase one or more of dihydroxyacetone kinase activity and transport of glycerol into the cell.
