Italy’s transport minister is questioning the spread of electric vehicle technology following the fiery crash of a fully electric shuttle bus that killed 21 people in mainland Venice.

But the battery chemistry used by the Chinese bus maker makes it less prone to catastrophic fires, experts said.

Chief Prosecutor Bruno Cherchi said Thursday there was no evidence the fire started before the bus hit the ground. Experts say that since lithium-iron-phosphate doesn’t store as much energy as other chemistries, it has less traveling range. But it’s also less prone to what experts call “thermal runaway,” when one battery cell overheats and causes chemical reactions and fires in the others.

“In many cases, for instance when the battery is operating normally, you can keep that oxygen within the structure,” Jayan said. “But if you have a fire, none of that works.” Salvini, who heads the right-wing Lega party, was criticized for focusing on electric vehicle technology when one of the elements under investigation is the guardrail that gave way, which falls under his purview as infrastructure and transport minister.

Nine Ukrainians were among the tourists killed, along with four Romanians, three Germans, two Portuguese, one Croat and one South African. All had been sightseeing in Venice and were traveling on the shuttle back to a campground on the Venetian mainland when the accident occurred.
