Biomass-derived Carbon Dots Enable Flexible, On-Demand Hydrogen Delivery . Methanol is a promising liquid hydrogen carrier for long distance H2 transportation and exportation, because it is rich in hydrogen content, cheap, recyclable between methanol-formaldehyde and easier to manufacture from renewable resources including biomass waste. The critical bottleneck in adopting methanol as the carrier is the demanding dehydrogenation process.

Methanol is a promising liquid hydrogen carrier for long distance H2 transportation and exportation, because it is rich in hydrogen content, cheap, recyclable between methanol-formaldehyde and easier to manufacture from renewable resources including biomass waste. The critical bottleneck in adopting methanol as the carrier is the demanding dehydrogenation process. The project aims to create a new class of photocatalyst based on biomass-derived carbon nanodots grown on transition metal (di)chalcogenide nanosheets that can effectively enable a light-controlled methanol H2 release of desired quantity. The key outcomes will be a new class of photocatalysts and flexible, on-demand hydrogen delivery technology for liquid hydrogen carriers.Read moreRead less
A New Spin on Liquid Hydrogen: Controlled Cold Energy. While hydrogen is set to play a leading role in global decarbonisation, significant challenges remain regarding methods for its reliable storage and transportation. Hydrogen liquefaction has emerged as a promising approach in this regard due to its high energy density and hydrogen purity, but is currently prohibitively expensive. In this project we will exploit the peculiar spin physics of hydrogen to alleviate liquefactions costs through t ....A New Spin on Liquid Hydrogen: Controlled Cold Energy. While hydrogen is set to play a leading role in global decarbonisation, significant challenges remain regarding methods for its reliable storage and transportation. Hydrogen liquefaction has emerged as a promising approach in this regard due to its high energy density and hydrogen purity, but is currently prohibitively expensive. In this project we will exploit the peculiar spin physics of hydrogen to alleviate liquefactions costs through the provision of controllable refrigeration (so-called 'cold energy') following regasification. In particular we will measure, optimise and exploit the highly endothermic catalysed conversion of para- to ortho- hydrogen, which can provide up to 525 kJ/kg of cooling at convenient temperatures.
