BMW presents liquid hydrogen storage for cars

BMW presents liquid hydrogen storage for cars

The California Air Resources Board wrapped up its Zero Emission Vehicle Technology Symposium yesterday, which covered everything from new battery technologies to hydrogen-powered airplanes. Although I didn't attend the symposium, some highlights that I found particularly interesting were a presentation on BMW's work on using liquid hydrogen in cars, Altairnano's use of lithium titanate in batteries, and AeroVironment's development of hydrogen fuel-cell airplanes. Boiled down, the message from the presentations is that while researchers continually make small breakthroughs, alternative energy storage in vehicles won't approach gasoline-equivalent numbers until 2015. Many of the presentations are available as PDF files here.
