Popular posts this month on a novel application for street lighting, and an original action to demonstratethe passive concept - the ice challenge. A reference information source on solar troughs and a technology with the prospect to halve the cost of solar energy. The carbon market is booming and carbon prices are expected to rise near year. But beware of the carbon cowboys! Finally, several island communities realise that renewable energy makes a lot of sense.

In this feature article, Ludwig Lindner argues that the prospect of a hydrogen economy is small. Hydrogen would make most sense for mobile applications (vehicles), provided that hydrogen is produced from CO2-free sources, such as nuclear, hydro-power or renewables (wind, solar).

A solar hydrogen economy, where hydrogen is produced in solar-rich areas using large-scale photovoltaic facilities, will be prohibitely expensive for the foreseeable future.
