Shell makes case for hydrocarbons in EVs

The whole point of EVs is to cut down on the use of hydrocarbons and reduce CO2 emissions, but Shell thinks it has a strong case for reintroducing them, at least for one very specific area.

Cooling electric vehicle batteries is becoming more of an issue as increased charging speeds and more performance applications test the limits of standard indirect cooling.

Indirect cooling for EVs is similar to that used by combustion engines. A jacket surrounds the battery pack and a water/glycol mix is pumped around. But that has its limits. To effectively and quickly reduce temperatures you need to swamp the cells themselves, and for that you need a so-called dielectric fluid — one that does not conduct electricity.
