The Kingdom of
Tonga is a Polynesian country and archipelago comprising 169 islands, of which 36 are inhabited. The total surface area is about 750 square kilometres (290 sq mi) scattered over 700,000 square kilometres (270,000 sq mi) of the southern
Pacific
Ocean. The sovereign state has a population of 100,651 people, of whom 70% reside on the main island of Tongatapu.
Tonga stretches across approximately 800 kilometres (500 mi) in a north-south line. It is surrounded by Fiji and Wallis and Futuna
(France) to the northwest, Samoa to the northeast, Niue to the east, Kermadec (part of New Zealand) to the southwest, and New Caledonia
(France) and Vanuatu to the farther west.
Tonga became known in the West as the "Friendly Islands" because of the congenial reception accorded to Captain James Cook on his first visit in 1773.
Tonga
began implementing policies to power its remote islands in a sustainable way without turning to expensive grid-extensions. A number of islands lack a basic
electricity supply, a supply
coming from imported diesel: in 2009, 19% of GDP and 25% of imports consisted of
diesel.
In view of the decreasing reliability of fossil-fuel electricity generation, its increasing costs and negative environmental side-effects, renewable energy solutions have attracted the government's attention. Together with IRENA, Tonga has charted out a
renewable energy based strategy to power the main and outer islands alike. The strategy focuses on Solar Home Systems that turn individual households into small power plants. In addition, it calls for the involvement of local operators, finance institutions and technicians to provide sustainable business models as well as strategies to ensure the effective operation, management and maintenance once the systems are installed.
With the assistance of IRENA, Tonga has developed the 2010–2020 Tonga Energy Road Map (TERM), which aims for a 50% reduction of diesel importation. This will be accomplished through a range of appropriate renewable technologies, including wind and solar, as well as innovative efficiencies.
Tonga
is not hydrogen ready as we write, hence clean fleet operators
will have to seek alternative handling facilities to comply
with the IMO's
2040 target.

7TH
LEG - At
a speed of 13 knots the seventh leg of the hydrogen
powered zero carbon voyage
would take just over a day to complete, free of emissions.
The demonstration of ZEWT
technology in action, could help speed up the transition to
non polluting waterborne
transport. These projections are only a guide. Many of the
ports of call could be bypassed completely to give us a
shorter passage.

SOLAR
POWERED TRANSIT
EXAMPLES - The above table illustrates one of the most likely
climate/ocean awareness expedition routes that could be undertaken by the
Elizabeth Swan, showing the time elapsed in days for 7 knots average
cruising speed, including times for 5 and 6 knot averages - allowing for
10% downtime and 36 days in ports. Hence, although the objective is to
reduce the current solar
circumnavigation
record from 584 days, the event in not an outright non-stop yacht
competition in the offshore racing sense. The
solar powered Elizabeth Swann is capable of speeds above 15 knots in the right
conditions.

JULES
VERNE - WORLD HYDROGEN CHALLENGE: The
climate clock is ticking faster, speeding up global
warming. So, can we do anything about it? Maybe. The Elizabeth Swann
platform, can be adapted to a long range cruiser with up to 4000nm
on hydrogen tanks alone. Using LH2, it might be possible to
circumnavigate
the globe on one tank full - and using solar in combination, travel Around
The World In 80
days. Without hydrogen
bunkering at ports and harbours it is more of a logistical
challenge. This is a problem for port
authorities and operators all over the globe, a topic for COP26
and similar events - as the world continues to fry on fossil fuels.
