Sunlight on the ocean surface other sectors of the economy. Firstly, the largest use of energy in Malaysia is in the transport sector by as much as 46% [16]. Since the pricing of energy does not differentiate by its form nor its source, but only its energy content, the price of petrol without the subsidy would be the same price as that of hydrogen fuel. For the same cost of energy, hydrogen-fuel cars, for instance, would travel more than double the distance than their counterparts powered by petrol [17]. That would save the economy not only in terms of “dollars and cents” but also in keeping the environment free from motor-vehicle emissions and pollution. Secondly, unless the pricing of energy in Malaysia reflects its true cost of generation- distribution-and-retailing, hydrogen economy would not make many inroads into other sectors of the economy: industry (27%), residential and commercial (15%), non-energy use (12%), and agriculture (2%). As much to support this Policy- intent as to help the underprivileged, including the B40 Group [18], the current fuel subsidies should be removed, and be replaced with “targeted support” for such selected groups of consumers. Only with the removal of such fuel or power subsidies would Malaysia begin to realise its other useful energy programmes including energy saving, energy conservation, energy efficiency, to be successful. Conclusion By the middle of the 21 st Century, hydrogen fuel will be a dominant energy carrier. In Malaysia, and in other countries in the tropics, this fuel would be generated largely by the conversion of ocean thermal energy from the sea where the waters are deep, deeper than 800m [20]. This fuel would be best used in the transport sector, it being the largest energy consumer, and its inroad into other sectors of the economy would be pronounced should there be any shift in the current energy policy toward “true energy pricing” with the removal of the subsidies. In the meantime, the application of hydrogen fuel cells would grow not only in the transport sector but also in other sectors, where independent and distributed power systems would be required. 29
