Hydrogentech has a simple and cost effective solution to supply electricity 24 hours a day using solar panels (this solution may also be implemented using wind turbines.) The system is depicted below. This environmentally friendly plant is totally without CO2 or other greenhouse gas emissions, and this improved solution has the following advantages over earlier systems:

How this works:
When the sun is shining solar panels from farm deliver electricity via a converter to meet the customer demand while solar panels from farm ‘B’ simultaneously produce electricity for use in the alkaline electrolyser. The electrolyser produces both hydrogen and oxygen which is then stored in separate tanks.
When the sun is not shining, the hydrogen (and in some cases even the oxygen), is converted back into electricity by means of a fuel cell. The electricity is sent to the end user via a converter. When day turns into night, or when it is overcast, solar farms are coordinated to provide sufficient electricity to meet the demand at all times.
The H2O vapour from the fuel cells may be captured in a condenser and used as drinking water or be fed back into the electrolyser in a closed loop.
