New US study says GHG benefits from hydrogen limited

Thu 01 November 2007 View all news

A new study by the US-based Reason Foundation claims that making the switch from petrol to hydrogen cars would not help to reduce greenhouse gas emissions.

The Reason Foundation report entitled "Are Hydrogen Cars Good for America?" says that if the U.S. replaced 20 percent of today's vehicles with hydrogen cars, CO2 emissions would either drop a tiny amount from 1.67 billion tons per year to 1.63 billion tons, or actually rise to 2.13 billion tons a year, depending upon what method is used to produce the hydrogen.  The report states that this is due to the considerable amount of conventional energy needed in the transport and production of hydrogen for use in fuel cells.  Additonally, the production of hygrogen would increase the need for foreign-produced natural gas.
