First Indian biofuel ship set for fleet review
Kalyan Ray Visakhapatnam: Feb 6, 2016, DHNS
When President Pranab Mukherjee will review the naval fleet on Saturday,
a small Indian naval vessel with green bands on both sides may emerge as
the centre of attraction as it would be the first Indian ship to run
completely on biofuel.
“At the international fleet review, we would be operating a fast
interceptor craft on green fuel,” Navy chief Admiral R K Dhowan said
here on Friday. Whether more warships would shift to cleaner fuel in the
future would depend on the success of this pilot project.
Dhowan said the Navy had initiated another green project to set up an
ocean thermal energy conversion plant in the Andaman and Nicobar islands
to generate electricity from the temperature difference between cold
water in the deep and warm water at the surface. So far, none of the
OTEC plants in the world — barring one in Japan — are successful.
The only Indian OTEC plant (1 MW) tried in 2002 by National Institute of
Ocean Technology, Chennai was a failure.
The naval OTEC project involves participation from foreign and Indian
industries and two sites have been identified in the Andaman to set up
the plant.
These green steps are aimed at reducing the Indian Navy’s carbon
footprint in the line of the US Navy that raised a Great Green Fleet in
which the US Navy is experimenting with the idea of warships using
alternate fuel and test the viability and strategic utility of the
concept. The US green fleet is a carrier battle group in which the
aircraft carrier is nuclear-powered while cruiser, destroyers, oil
tanker and aircraft run on a 50:50 mix of petroleum and biofuel. Indian
Navy has undertaken several more green steps. For instance, it has been
decided that all future acquisition and upgrade projects would also have
to factor in energy efficiency to reduce the emission load. Karwar naval
base, which houses aircraft carrier INS Vikramaditya, has zero carbon
footprint. In its expansion phase, more green measures are being
incorporated.
The Indian Navy, however, is yet to decide if its planned second
indigenous carrier would use nuclear propulsion or would be a diesel
guzzler.
