Has anyone seen the energy balance? Electrolysis of water is only 70-75% efficient, so unless there is some other form of energy being released, you only get out about 3/4 of what you put in.
Since mid-January 2009 the first seawater heating plant in the world can be found in Scheveningen. The plant will pump seawater from the Scheveningen Harbour to provide the nearby neighbourhood of Duindorp with water at a constant temperature of 21 degrees Celsius.
The seawater heating plant is a unique concept which uses a heat pump and heat exchanger to extract heat from the sea. The water plant is part of the city’s plan to use more sustainable energy and is one of the steps being taken towards making the area ‘climate neutral’ in order to reduce energy usage.
According to Deerns Engineering Consultants, the central heat pump provides a highly efficient means to raise the water temperature to the right level in the winter when the temperature of the sea water is too low. The overall efficiency of the heat generation process with this system is more than 50% better than with conventional high-efficiency boilers, while the cost to the residents is no higher.
