German start-up Kraftwerk has developed a liquified natural gas (LNG) battery, and claims it, and not lithium-ion, is the future of electric vehicles. Co-founder and former LNG employee Kraftwerk said the LNG battery would be suited for deployment in Hong Kong , where the LNG fuelling infrastructure already exists. Martin Pentenrieder 's battery, which relies on a chemical reaction after the injection of LNG into a fuel cell stack, has a well-to-wheel efficiency ratio of at least 45% . Several large carmakers are said to be interested in the project.
