Hydrogen storage in porous frameworks
Hydrogen has the highest gravimetric energy density of any fuel, but storing it safely at ambient conditions is the central challenge for mobility and stationary applications.
Our approach
- Physisorption engineering: optimising isosteric heat of adsorption (target: 20–30 kJ/mol) through open metal sites, ligand functionalisation, and defect engineering
- Working capacity: targets of 5 wt% excess H₂ at 100 bar/298 K — validated on our sorption bench (6 stations, liquid-N₂ to 423 K)
- System integration: breakthrough column experiments to simulate tank charge/discharge cycles
Record materials
Our MIL-101(Cr)-SO₃H reaches 4.8 wt% excess at 77 K/60 bar; room-temperature variants are currently under optimisation with DOE targets in sight.
