Towards zero emission shipping

we need a new power source for ships, hopefully it will come at the same price so as HFO fuelled 2 stroke IC so people will change, emissions being the selling point.
If its cheaper then a no brainer

Shut down BECAUSE OF or DESPITE Trump?

Decarbonising shipping is a hot topic in Maritime media at the moment:

The UK (and ergo UK fleet) is moving faster -net carbon neutral by 2050 as opposed to IMO 50% reduction in 2050. Scotland even harder with net carbon neutral by 2045. I have a vessel renewal issue…

One small step towards reduced emission from ships is to reduce fuel consumption on existing ships:

Every little step helps.

lol counldnt say

China is betting on Methanol as the Marine fuel of the future. (At least according to this article):

Maybe China is betting on the right solution?:


If so it is good news for Marine Engineers, (maybe??)

Japan is looking at producing Methane from CO2 captured at steel plants, using hydrogen produced with renewable energy as catalysator:

That’s nice but in the global scheme of things isn’t it just another form of whack-a-mole?

Well, if you wack enough moles it may do the trick.
This one wacks two moles at the same time, but that doesn’t mean it solve the problem totally.
Before that can happen there have to be a worldwide agreement and will to solve it.

It only makes sense if you can get your hydrogen electrolytically and without burning fuel to do it.

There is a lot more to it than just the hydrogen component.

Burning methane reduces the amount of CO2 and particulates per BTU produced compared to other fuels but it does not eliminate CO2 and other greenhouse gases, it just moves them from one place to another.

Methane has a global warming potential (the nasty aspect of greenhouse gases) of 28 to 36 times that of CO2 so any leak or accidental “spill” or even the “methane slip” that results from imperfect combustion can negate much of the benefits.

If they found a way to sequester the CO2 they collect from the mills rather than use energy and fuel to liquify and transport it to a place where methane and hydrogen has been shipped from halfway around the globe then ship it to a bunkering port they might do something better.

That is the plan, I believe:

PS> Japan is investing heavily in renewable energy, or is at least planning to:

they are also building lots more coal powerplants, but clean coal ones I assume?

Of course. They wash the coal first.

Yes Japan is planning to build 22 new, efficient coal fired power plants:

Yes “Clean Coal” technology will be employed,

They are also planning to shut down 100 old and inefficient plants:

Wartsila is looking at Ammonia as a fuel for it’s engines:

PS> Ammonia can also be used to power fuel cells.

What does “Zero Emission” really mean for the shipping industry?:
