BALTIC - A proposed zero emission ferry from Denmark to Germany.

 

 

FUEL CELL TODAY OCTOBER 2012 - FUTURE SHIP DESIGNS ZERO EMISSION FUEL CELL FERRY FOR SCANDLINES

Further to Scandlines’ expression of interest in fuel cell ferries for the Fehmarn Belt crossing between Denmark and Germany, a shipping efficiency consultancy has produced a design for the proposed ferries.

Germanischer Lloyd subsidiary FutureShip has developed a zero-emission propulsion concept for Scandlines, which could be implemented on the Baltic ferries within the next five years.

The zero-emission ferries have 8.3 MW fuel cells and 140 m3 hydrogen tanks, sufficient for a passage of 48 hours, as well as storage batteries with 2.4 MWh capacity. The ferries travel at 17 knots but can accelerate up to 18 knots by drawing additional power from the batteries. Flettner rotors harvest wind energy.

FutureShip estimates that the ferries would cost only about 25% more than a conventional design and says they could be built with technology available today.

 

 

Cross Channel Ferry

-

SOLAR & WIND POWERED FERRY - The Cross Channel Challenger (CCC) is a project currently on the drawing board looking for backing to develop a coastal cruiser that is zero carbon just like the hydrogen projects, but where the vessel converts energy from nature onboard for propulsion without risk of hydrogen leaks or fires.

 

This is a toe-in-the-water project using budget off the shelf equipment to keep the costs down. Hence, the theoretical performance is lower than might be achieved but higher than the current benchmark. It is a useful stepping stone to medium range ferries and eventually bigger ships with longer ranges. Solar combined with wind power could be the winning combination. Comparing the two technologies will be interesting. For sure, the solar powered ferries will be safer and cheaper.

 

Solar and wind powered vessels do not need big hydrogen tanks next to docks for ships to fill up from. They do not need trucks to deliver the hydrogen from the conversion plants and last but not least, hydrogen is potentially dangerous, as the Zeppelin 'Hindenburg' demonstrated in 1937 when a spark ignited the fated airship, destroying it in minutes.

 

 

 

 

CONVERSION, CONVERSION, CONVERSION - It is the number of additional stages of splitting water using electricity, storing as a gas and then recombining it to extract the electricity that was put in at the beginning at a huge net energy loss. Elon Musk has a point don't you think?

 

 

Hydrogen is recognised as a fuel with the potential to deliver 100% zero-carbon operation in marine transport, but the systems proposed so far are expensive and complicated, where the first rule of engineering is to Keep It Simple Stupid: KISS.

 

The allure of the hydrogen economy is plain, splitting ordinary water using electrolysis to obtain oxygen and hydrogen gas is like a schoolboy chemist dream come true, especially if we can generate what appears to be free electricity using solar cells and wind turbines to split the water. Then the hydrogen is free right?

 

No, not really.

 

There is a cost, including the cost of manufacturing the solar panels or wind turbines and the transmission line installation and maintenance. The inefficiencies in the conversion and handling chain make hydrogen expensive to produce and so potentially un-competitive - as compared to using the electricity needed to convert water, directly.

 

In addition, hydrogen is dangerous unless stored very carefully. Space rockets powered by hydrogen and oxygen sometimes explode, with the Hindenburg zeppelin explosion being signs of things to come in a world fraught with human error. We'd be courting disaster. If something can happen, it will happen. Passengers would be traveling in potential time bombs.

STUDY PUBLISHED - Point and Sandwick Trust, in collaboration with a number of industry partners (Wood, Siemens-Gamesa, Engie, ITM, CMAL, Johnston Carmichael and Ferguson Marine), have published a feasibility study to assess the suitability of using hydrogen produced from local wind farms to power future ferry services operating in the Western Isles and West Coast of Scotland.

The study was part-funded by the Scottish Government’s Low Carbon Infrastructure Transition Programme. Read the full report here.

The project looked at the practical and economic feasibility of using new island wind farms to produce zero-carbon “green” hydrogen fuel for future types of clean emission ferries operating on the established Caledonian MacBrayne routes.
