As with many technological developments the cheaper the innovation the quicker it will be adopted and the more likely it will be to stand the test of time, in this way hydrogen looks to be a more likely next step in environmentally friendly vehicles. While both electric and hydrogen vehicles are set to be a lot more expensive than fossil fuel powered vehicles the process of raw material extraction that is required to make lithium batteries far outweighs the abundant levels of hydrogen, hydrogen being more a question of the expense of storage and safety and also electric vehicles will require the much larger cost of all new infrastructure that is ultimately powered by electricity generated by fossil fuel . DO you think that electric cars will be the answer to future transport needs?
