Replacing the Subs

Noah over at TNSR has a writeup about his visit to Hanwha's shipyard at Geoje and I must say its pretty interesting!

I am not sure what you mean.

If you are sharing resources the group you are sharing with has a say in what you do with it. For example the Swiss will not sell any weapons into an armed conflict. So we have a problem on the west coast with China and our interests there and Germany who has lots of dealings with China says you can't go there. They own a third of the fleet if it is a truly shared system so they get a veto.

Gotcha!

The Germans don’t seem to be squeamish about that sort of thing.

Seemed like a great commercial for the future of Ontario Shipyards. I haven't heard any rumours around town regarding any upgrading going on at the moment and their assemby building in Port Weller is currently a cement plant.

Canada will have full control. That's a pretty common thing in our purchases.

Stand by for (alleged, at least) decision in the next few weeks?

International competition to build Canada's next submarine fleet enters home stretch

How do we feel about trucks that run on hydrogen?

EXCLUSIVE: South Korea boosts submarine bid with ‘Project Beaver’ hydrogen truck proposal

The secret weapon in South Korea’s bid to win the lucrative submarine contract is code named 'Project Beaver,' aiming to bring manufacturing jobs to Canada through hydrogen trucks.

www.ctvnews.ca

Facing market conditions that blocked it from bringing an electric vehicle plant to Canada, the South Koreans drafted a plan to manufacture hydrogen long-haul freight trucks and build dozens of charging stations in Canada, beginning in 2030. The proposal was submitted as part of Hanwha’s bid for the submarines, and the details were kept under wraps until now.

“Project Beaver” will use the technology developed by Hyundai Motors and transplant it to Canada.

Don't have time to watch it yet, but here is a primer video for you and AI says this:

By mass, hydrogen contains nearly three times more energy than diesel (\(120 \text{ MJ/kg}\) vs. \(45.5 \text{ MJ/kg}\)). However, because hydrogen is a very light gas, it has low volumetric density unless highly compressed or liquefied. Depending on how the energy is used, power output varies significantly: [1, 2, 3, 4, 5]

• Hydrogen Fuel Cells: By pairing hydrogen with a fuel cell to drive electric motors, vehicles generate power outputs, torque, and acceleration comparable to (or exceeding) heavy-duty diesel engines. Fuel cells are also more efficient, converting \(50\text{--}60\%\) of the fuel's energy into useful work, compared to diesel's \(35\text{--}45\%\) efficiency. [1, 2, 3, 4, 5]
• Hydrogen Internal Combustion (H2-ICE): Hydrogen can also be burned directly in modified combustion engines. Because hydrogen burns faster and has superior flame speeds, these engines can achieve the same power and torque outputs as traditional diesel motors. However, to avoid power drops from the lower volumetric energy density of the fuel, engineers must optimize air-fuel ratios and sometimes use direct fuel injection

A large impediment to Hydrogen as vehicle fuel is the lack of infrastructure (fueling locations) to support it.

if you are only doing big rigs, and commercial traffic, it will be easier short term to set that up, but it still requires a fair amount of investment

Ask the crew and passengers on the Hindenburg ?

Not really a fair comparision.
