Towards zero emission shipping

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:,-Wärtsilä’s%20recent%20experiments&text=Ammonia%20can%20be%20created%20with,a%20cleaner%20and%20sustainable%20world.

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

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

Is it just me or I just find it hard to swallow that the worst industry is going to pass all others and be zero emissions.

It could be “Only you”.
Not many people are a negative to everything as you.

I think the 2 sides of this argument are dreamland and reality
I fully expect you to post this headline one day…
By 2050 ships will float across the world on negative gravity machine and pushed by solar winds so they meet their zero emissions target

Aren’t they already doing that in Singapore?

Shippers and shipowners share costs of using Biofuel yo reduce GHG emission:

Isn’t that a kind of Mexican soup?

very hard to get anyone to define what biofuel is and what its carbon footprint actually is

Hyundai has obtained class approval in principle for Ammonia fueled ships:

While others are looking at Hydrogen as the future fuel for ships:
