AROUND THE WORLD IN 80 DAYS

ADEN - HYDROGEN BUNKERING ROUTE PLANNER

-

Aden is a port city and the temporary capital of Yemen, located by the eastern approach to the Red Sea (the Gulf of Aden), some 170 km (110 mi) east of Bab-el-Mandeb. Its population is approximately 800,000 people. Aden's natural harbour lies in the crater of a dormant volcano, which now forms a peninsula joined to the mainland by a low isthmus.

Historically, Aden would import goods from the African coast and from Europe, the United States, and India. As of 1920, the British described it as "the chief emporium of Arabian trade, receiving the small quantities of native produce, and supplying the modest wants of the interior and of most of the smaller Arabian ports." At the docks, the city provided coal to passing ships.

Yemen is in Western Asia, in the southern part of the Arabian Peninsula, bordering the Arabian Sea, Gulf of Aden, and the Red Sea. It lies south of Saudi Arabia and west of Oman, between latitudes 12 and 19°N and longitudes 42 and 55°E. Yemen is at 15°N 48°E. Yemen is 527,970 km2 (203,850 sq mi) in size.

A number of Red Sea islands, including the Hanish Islands, Kamaran, and Perim, as well as Socotra in the Arabian Sea, belong to Yemen.

A key challenge is severe water scarcity, especially in the Highlands, prompting The Times to write "Yemen could become first nation to run out of water.

Among Yemen's natural and cultural attractions are four World Heritage sites. The Old Walled City of Shibam in Wadi Hadhramaut, inscribed by UNESCO in 1982, two years after Yemen joined the World Heritage Committee, is nicknamed "Manhattan of the Desert" because of its "skyscrapers." Surrounded by a fortified wall made of mud and straw, the 16th-century city is one of the oldest examples of urban planning based on the principle of vertical construction. Aden 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.

14TH LEG - At a speed of 13 knots the fourteenth leg of the hydrogen powered zero carbon voyage would take just over 2 days 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.

A RACE AGAINST THE CLIMATE CLOCK: The climate clock is ticking faster, speeding up global warming. Solar power is a proven means of traversing the oceans, but it is too slow for cargo transport as we write. But introduce hydrogen into the equation and we can manage 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.   http://jules-verne.org/   http://jules-verne.org/
