Ground-breaking liquid hydrogen fuel gas system developed to power marine engines



12/7/18 Tami Hood

The marine fuel-gas system was developed by MAN Cryo.

A versatile marine liquid hydrogen fuel gas system has been developed by Sweden-based MAN Cryo in cooperation with ship owner Fjord1 and ship designer Multi Maritime in Norway. MAN Cryo is a marine technology and engine manufacturer and a wholly owned subsidiary of MAN Energy Solutions.

The unique fuel gas system has won preliminary AIP.

Multi Maritime’s hydrogen design for Fjord1, which includes MAN Cryo’s fully integrated Hydrogen Fuel Gas System, has been awarded preliminary approval-in-principle (AIP), by the DNV-GL Classification society.

Receiving this approval is important for a variety of reasons, according to CEO of MAN Energy Solution, Dr. Uwe Lauber.

“As a solution for vessels employed on relatively short maritime routes, such as ferries, this technology is a world-first and showcases our company’s ability to deliver genuinely innovative solutions,” Lauber said, reported Gasworld.

The marine liquid hydrogen fuel gas system has a scalable design...more: http://www.hydrogenfuelnews.com/ground-breaking-liquid-hydrogen-fuel-gas-system-developed-to-power-marine-engines/

World's First Hydrogen-Powered Cruise Ship Scheduled

BY MAREX 2017-10-03 14:24:36

Viking Cruises has joined the ranks of shipping companies working to introduce fuel cell technology with the announcement last week of plans to build the world’s first cruise ship fueled by liquid hydrogen.

Project manager Serge Fossati told a shipping conference in Norway that the ship will be around 230 meters long and will accommodate more than 900 passengers and a crew of 500. She will be based on the design of the cruise line's other ocean-going ships, such as the Viking Sun. Several tender ships to carry the fuel to the cruise ship are also part of the project.

So far, liquid hydrogen has not been used as marine fuel. A fuel cell will convert the hydrogen to electricity for propulsion and electric power on board. A fuel cell power pack consists of a fuel and gas processing system and a stack of fuel cells that convert the chemical energy of the fuel to electric power through electrochemical reactions. The process can be described similar to that of a battery, with electrochemical reactions occurring at the interface between the anode or cathode and the electrolyte membrane, but with continuous fuel and air supplies, Different fuel cell types are available, and can be characterized by the materials used in the membrane...more: https://www.maritime-executive.com/article/worlds-first-hydrogen-powered-cruise-ship-scheduled

1. It's always interesting how the operating costs of this system is never mentioned........

2. None of his articles ever mention costs.

I wonder why?

3. Money is no object for him

That is why he owns and operates a hydrogen powered car.

4. You aren't paying for it.

It's been mentioned here several times how much it costs to produce and store hydrogen.
How much the engines cost and all that.
Yet everyone always asks the same questions over and over.

6. Do you live in Norway and own Fjord1?

If not, then you aren't paying for it.

7. Oh, good. Could you point me to one of those articles

that mentions the cost to produce hydrogen? I'm quite familiar with the field, and I have been unable to find one.

I've seen articles (I even posted some) that mention that it takes approximately 50 KWh of electrical energy to produce one kilogram of H2 in current electrolyzers. From that one can then calculate the cost of the input electricity at your current rates. However, that is just part of the operational cost of production. I have not seen any mention of the capital cost of an electrolyzer unit, it's lifetime production capacity (thus to calculate per unit production cost amortization), nor the on-going maintenance costs of such an electrolyzer unit (cleaning, filters, periodic replacement of contaminated catalysts, etc.) that are also contributors to the production cost per kilogram of H2. Those things all count in the cost of production of a unit of H2.

The cost of storage I have not seen detailed or analyzed at all.

So, please tell me, from one of the mentions that you have see here, how much it costs to produce and store hydrogen. I am really interested.

Thank you.

8. Those things are all easy to find.

They have been mentioned here as well.
You can go through the dozens of hydrogen threads to find them if you'd like.
An Internet search would probably be quicker.
The person posting all these isn't writing the articles and isn't obligated to do your research for you, nor am I.

You can't.

10. I'm not your fucking servant.

If you really cared you'd find out for yourself.
You don't care, you just like asking the same questions over and over again like it makes some kind of point. It doesn't.

I could call my old boss right now and ask him how much his electrolysers cost and how much it costs per Kg of Hydrogen/Oxygen they produce, maintenance etc.. but I don't care. So why would I?
You claim to care, just not enough to actually find out for yourself.

You said it was mentioned right here. Guess not.

Good day.

12. Sigh

Call my old boss.
That's one way that if I cared I could find out.
You said I can't. That is one way I actually can find at least 3 answers for you. I could also research it.

Your inane attempts at making a point by repeating yourself and others is lame and boring.

If you cared, you'd know. Plain and simple.

Laziness doesn't impress me and I don't mind helping people that will at least attempt to help themselves. You aren't one of those people.

13. OK, I'm crushed.

"It's been mentioned *here* several times how much it costs to produce and store hydrogen. "

Sigh.

I won't bother you again.
