H2 Boiler Research. As a group we have reviewed a domestic PV-fuel cell energy system.
The system requires only the direct inputs of water and sunlight into the proprietary process of which the main system components are a PV array, electrolyser, hydrogen storage, and a fuel cell. The basic system is illustrated below. Figure 1: Basic system diagram The basic principles of the solar hydrogen system is that the photovoltaic array supplies electricity directly to an autonomous dwelling in periods of high solar irradiance and surplus electricity is used to generate hydrogen gas that can be stored on site. Solar cell directly splits water for hydrogen - StumbleUpon. Boston, Mass. -- Plants trees and algae do it.
Even some bacteria and moss do it, but scientists have had a difficult time developing methods to turn sunlight into useful fuel. Now, Penn State researchers have a proof-of-concept device that can split water and produce recoverable hydrogen. H2-NRG.
