Via Slashdot, we discover that a Leuven-based research team have managed to modify solar cells to decompose water into its component parts and produce hydrogen in situ.
The system harvests moisture from the air while generating photovoltaic power and the dual-application really reveals itself as complete, self-sustaining (if it can be scaled up) and self-sufficient as trials suggest that a small array of panels can procure enough power to light and heat a smallish living space without adding to the household’s carbon footprint. Demonstration projects are already underway in the UK and Belgium that keep homes warm using hydrogen instead of natural gas and can use the alternate fuel with existing pipes and infrastructure with relatively little retrofitting required. If the hydrogen does not need to be pumped in from outside, the process becomes even more efficient.
