Hydrogen vs. Battery Electric Cars

Hydrogen may well come into its own in some markets, and in the medium to long term. The problem with lithium batteries is that elements needed to build them are becoming steadily more expensive and harder to acquire.  Unless some of these miracle new batteries are proven to work and can be made economically then BEVs as we know them will be priced off the market. In NZ where 95% of electricity is made from renewable resources (mainly hydro) Hydrogen could become a viable fuel for cars and trucks...if not now then in 5 or so years.
