Energy-efficient lighting towers – explore ways to cut costs and CO2 this winter

Energy-efficient lighting towers – explore ways to cut costs and CO2 this winter | Passive Building | Scoop.it

The world’s first low energy LED hydrogen fuel cell powered lighting tower, powered by the BOC Hymera fuel cell. The Ecolite H2 can be used in locations that would normally be restricted, with the ability to run without diesel making it ideal for environmentally sensitive areas where a risk of contamination may occur.The Hymera fuel cell produces energy by combining hydrogen with oxygen from the air to form electricity and water. There are no carbon or particulate emissions and as a result the process is virtually silent which is important for work at night or in built-up areas. This is the first time fuel cells have been integrated into a low energy, low voltage LED system and using only 150W of energy.
