The Liquid Air Energy Network (LAEN) is the new forum for the advocacy and development of liquid air as an alternative way to harness waste and surplus energy within power and transport.
- Liquid air is a novel, energy storage solution that could play a key role in the low carbon energy future.
- The UK has world class expertise in both mechanical engineering and cryogenics.
The use of liquid air for grid-based energy storage could increase energy security, cut greenhouse gas emissions and create a new industry for the UK worth at least £1bn pa and 22,000 jobs to the UK. Liquid air technologies could also significantly increase the efficiency of road vehicles, particularly in commercial buses, vans and refrigerated lorry fleets.
HEP or NP Accelerators nowadays are all using superconducting cavities and magnets. In the old-time Liquid nitrogen was a necessary first step to cool down the large accelerator mass. LHC is not using liquid nitrogen and relies on cryocoolers based helium. ILC is planned to follow the same approach. Reintroducing liquid nitrogen as a first stage in cooling down the whole equipment would reduce dramatically the energy consuption to the expense of the increased complexity of handling an additional fluid which in certain loaction could be hazardous
It remains that liquid nitrogen which is a basic fluid in accelerator systems can also be the energy storage of choice in the attempt to build green accelerators (see the report on energy and transport)
