US Could Have 2 Million Hydrogen Vehicles by 2020

A new report by the US National Research Council suggests that hydrogen vehicles could be the future of the automobile industry. The report, “Transitions To Alternative Transportation Technologies: A Focus On Hydrogen”, says that there could be two million hydrogen fuel cell vehicles (HFCV) on American roads by 2020. This would make a big dent in the country’s dependence on fossil fuels and help reduce carbon emissions.

Unfortunately this is a best-case scenario. The report points out the obstacles to achieving the switch over from carbon-based fuels to hydrogen, including the cost of production and the lack of a support infrastructure.

In other words: it’ll cost money.

The report also looks at other alternatives to fossil fuels including biofuels, low-carbon fuels and more efficient conventional vehicles. Combining all of these could provide a significantly lower CO2 future for the US and help the fight against climate change.

If the American government and the people have the will to take the necessary steps.

Floods Threaten US and Europe First

Greenland Ice CapIf the polar icecaps continue melting then the sea levels will rise, causing floods. Up until now it had been thought that regions most at risk from the flooding would be tropical islands in the Pacific. However new research suggests that the US and Europe could be hit first.

Computer models run by Detlef Stammer of Hamburg University show that the pattern of flooding is unlikely to be even across the globe. Instead the water from the Greenland ice cap is likely to remain mostly in the Atlantic for almost fifty years. First to be hit by floods will be northern areas such as coastal areas of the US and Europe. In particular, sea-level rises on the East coast of the USA could be 30 times greater than in the Pacific.

That should serve to focus some minds!
