Eden used to dabble in cryogenic storage before selling off the tec so as to steam line the company. They had a system called SMESS, i forgot whe the acronym was short for but it worked by having a cryogenic fuel tank with coiled wire on the inside, this acted as a super conducive battery for a hybrid system. Eden also sold CNT in the early days to a battery company as well as to a paper company to make a conducive e-paper, at the time these markets weren't big enough to sell CNT in bulk.

Sorry for the lack of links, im on my phone and have provided them in the past
