World's First Fuel Cell Ship Docks in Copenhagen
Can fuel cells and natural gas help reduce emissions from shipping?
By David Biello
COPENHAGEN—Pleasure yachts and tall ships line the wharves and quays of Nyhavn here in the Danish capital. Shipping in Denmark goes back to the Vikings and their long ships that made perilous sea crossings even beyond Greenland. Now what may be the future of shipping is docked around the corner from Nyhavn at Kvaesthusmolen pier, a bright orange and yellow North Sea supply ship from Norway dubbed "Viking Lady"—the first ship to employ a fuel cell in history.
As a result of flourishing world trade, shipping is now responsible for roughly three percent of global emissions of greenhouse gases, or more than one billion metric tons of carbon dioxide every year, along with smog-forming nitrogen oxides, acid-rain causing sulfur dioxides and soot. In fact, emissions of nitrogen oxides from one ship burning diesel in a year are greater than those from 22,000 cars. That's because ships burn bunker fuel or diesel to cleave through the waves but, according to Tor Svensen, CEO of Det Norske Veritas (DNV) Maritime, "it is possible for shipping to reduce emissions, even taking into account growth in world trade."
snip
But in the case of the 5,900 metric ton Viking Lady, Norwegian shipping company Eidesvik and its partners have gone further, installing a 320-kilowatt molten carbonate fuel cell that operates on liquefied natural gas (and can be reconfigured, if necessary, to run on methanol). Storage tanks for the hydrogen and carbon dioxide that gets the fuel cell started press up against the stern of the 92.2 meter-long ship (in case of explosion) as do the machines to regasify the fuel. The fuel cell operates at 650 degrees Celsius and is warm to the touch, even on a blustery, frigid day in Copenhagen's harbor.
Already, liquefied natural gas is cheaper than diesel—if you can find it. Engineer and project developer Kjell Sandaker of Eidesvik notes there are as many as 15 such fueling stations along the Norwegian coast and the bright orange Viking Lady gases up once a week as its onboard turbines also directly burn the gas to supply electricity to the engines, though they can also burn diesel if necessary. The ship's 220 cubic meter tank can hold roughly 90 metric tons of liquefied natural gas at a time.

--------------------------------------------
Fuel Cell, electric powered ships, what an idea. I hope the fuel cell test is successful and they actually use it to power the electric motors on the ship. Also note, when you read the article, that there is a motivation to use natural gas because of a tax on nitrogen oxide emissions.

--------------------------------------------

But the investment was also made because Norway has a tax on nitrogen oxide emissions that paid an immediate return for installing gas rather than diesel engines, says Eidesvik CEO Jan Fredrik Meling. Compared to a traditional ship, even without using the fuel cell, the Viking Lady reduces nitrogen oxide emissions by 90 percent, CO2 emissions by 20 percent and eliminates sulfur dioxide and soot emissions.

-------------------------------------------
Now if they are to make a go of it they will need to have liquid gas stations at dockside. Slight paradigm shift required and as you might have guessed, aaaah, might need some government support.

-------------------------------------------
snip
Ultimately, whether the Viking Lady remains unique in the annals of shipping will depend on the political decisions that come out of the Copenhagen climate conference and in national capitals. "It will take 20 to 30 years for this technology without government support," says DNV's Tronstad. "If they want to act on climate soon, this is a technology that is available today."

-------------------------------------------
I wonder what would happen if every home used some low tech skills to get us off the power grid? I shall continue to see what R. Buckminster Fuller has to suggest.

Thanks for looking up with me.
