Hydrogen storage

The most promising safe storage technology so far has recently emerged from Japan and Hong Kong. It is nanofibre carbon. This consists of cylinders 0.4 nanometres (0.4 billionths of a metre) in diameter which is just right size to accommodate a hydrogen atom. A nanofibre pack has the capacity to store up to 70 per cent of hydrogen by weight compared to 2-4 per cent in a metal hydride. It is claimed that a cartridge in a hydrogen car could fuel it for 5000 kilometres. For buildings the storage potential is enormous.

Renewable Energy 101

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
