Looks
like the JUTC (Jamaica Urban Transit Company) is going to be going the LNG way.
The
Government of Jamaica has announced plans to fuel their buses using CNG
(Compressed Natural Gas), the compressed counterpart to LNG (Liquid Natural
Gas) as reported in the article “Pilot
Approved For JUTC To Use LNG”, published Wednesday December 20, 2017, The Jamaica Gleaner.
The
pilot, to be rolled out in Q1 of 2018, will see five (5) buses being
retrofitted to use CNG. Supposedly, they'll be marked to indicate to passenger
that they are using the fuel, should the public be wary of a bus that's
basically running on a gaseous combustible fuel.
The
aim is energy efficiency.
Prime
Minister Andrew Holness made the announcement during the launch of Red Stripe’s
new Line 8 production line and LNG plant at their Spanish Town Road facility on
Tuesday December 19, 2017.
They
are planning to basically reduce taxes on LNG to increase its usages; thus if
you are a motorists, when the GOJ decided to roll our LNG to the public, it'll
be tax-free.
According
to Transport and Mining Minister, Hon. Mike Henry, during his contribution to
the 2017/18 Sectoral Debate in the House of Representatives on April 12, 2017,
the use of LNG in buses has a projected fuel savings of 25% as noted in the
article “JUTC to Manage LNG
Pilot”, published April 13, 2017 by Latonya Linton, The Jamaica Information Service.
So
what exactly is CNG?
JUTC and CNG - A New
Spin on an old Idea
Compressed
Natural Gas (CNG) is a natural gas .e. methane, ethane, butane and propane fuel
that has been compressed to less than 1% of its volume at s.t.p. (standard
temperature and pressure) which is 0°C
Celcius at 1 Atm, 101.3kPa or 760 mmHg of pressure.
It's
naturally odourless, colourless and is inexpensive to produce and store, as
it's a lot like LPG (Liquid Petroleum Gas) or butane that is used in cooking
Gas cylinders; liquid with some evaporated gas fuel at the top.
This
readiness to be liquid and convert to a gas makes ideal for numerous large
vehicles such as:
1. Refuse
trucks
2. Buses
3. Shuttles
Buses
4. Taxis
5. Heavy-duty
trucks
The
liquid readily converts to gas at r.t.p (room temperature and pressure) which
is 20°C at 1 Atm, 101.3kPa or 760 mmHg of pressure. This means special storage
cylinders for the fuel is required. The fact that it gasifies so easily means
it burns more cleanly and evenly in a typical vehicle combustion chamber.
It
also does not need to be filtered, making it excellent for cars as well as
noted in my blog
article entitled “LPG
and the Challenger Transport Co Ltd - A Cheaper Fuel”
Good
to note here that the LPG (Liquid Petroleum Gas) used in cooking Gas cylinders
is a form of CNG, just that it is mainly composed of butane; This means that
CNG packs more energy per cubic meter. So it's really an upgrade on an old
idea.
So
is it really more environmentally friendly?
CNG and Renewables in
Jamaica - More emphasis need to be placed on Solar, Wind and Biofuel
Alas,
no!!
We
have to import LNG and gasify it to CNG at the pump or keep it below ground to
keep it in liquid state, making it non-renewable. LNG is really gas that should
have been burned off at the oilwell, but has been stored for resale at cheaper
rates, being ax most oilwells are full of LNG dissolved in oil.
Biodiesel,
albeit impractical to grow fuel, it's actually renewable as noted in my blog article
entitled “PCJ,
UTECH develop Castor Oil-based Biodiesel to reduce Oil imports by 97,000
barrels”; Biodiesel can even be made from cooking oil and other organic
sources.
Already
there is a pilot project for making Biodiesel from waste cooking oil from
restaurants from across the islands as explained in my blog article
entitled “How
UWI and YCWJ can Waste Cooking Oil for National Bio-Diesel Production”.
This
is actually more economically sustainable, as the Biofuel required to run the
buses can also be made from organic material. Also, the infrastructure for LNG
for cooling and compressing, shipping and regasifying can be extensive and expensive, and may cost
the government in the long run.
The
only way this could be cheaper is if the GOJ has excess energy that they may be
planning to use for compressing and regasifying LNG to CNG, such as from Wind
Turbines as described in my Geezam blog article
entitled “How PCJ Offshore
Windfarm may be used to export Hydrogen and Uranium”.
I
suspect the GOJ and the PCJ is going this route of continuing to import a
fossil fuel as they are getting funding from the USA and other agencies. LNG Can reduce the cost of both motor vehicle
fuel as well as electricity generation once fully adopted by Jamaica along with
true Renewable Energy sources such as Solar and Wind as pointed out in my blog article
entitled “IEA
says Solar PV is fastest growing Energy source while Jamaica is adopting LNG”.
Hopefully,
the PCJ will promote Renewable Energy sources such as Solar, Wind and Biofuel
from organic material and not lead Jamaica back to an over dependence on an
imported fossil fuel.
