The Lemming's Rush to Net Zero 6

[rb1957]

beat me to it ! thx, greg.

and we produce a lot of CO2 for non-power applications, too.

I wonder how much waste heat is exhausted at a nuke ? How much water vapour this "typically" creates ?

There is a price to pay for net zero (if possible to achieve).

"According to an electricity system simulation and economic analysis conducted by the Ontario Society of Professional Engineers (OSPE), retail electricity rates in Ontario could more than double, in some scenarios, to achieve net zero for province’s electricity system by 2035.
Specifically, the engineering association’s study found that adding too much intermittent renewable generation to the grid, particularly photovoltaic with battery backup, would spike rates as much as 220 percent in todays dollars.

In contrast, the OSPE simulation predicts that adding nuclear generation, with pumped hydroelectric storage, would increase 2035 retail electricity costs by roughly 20% higher in todays dollars.

In total, OSPE’s analysis explored 10 supply mixes, including hydroelectric, nuclear, wind turbine, PV, storage, and renewable natural gas combustion turbines, matching the existing zero-emission installed capacity in 2021."

And you expect that Canadian consumers will accept those extra costs? For what good, when no other country will do the same? The Canadian example just shows that this 'Net Zero' nonsense will never be achieved. Rather than commit economic suicide, adapt.

Germany has just shut its nuclear reactors down and is now importing record amounts of electricity, largely from Poland (coal) and France (nuclear).

For the planet!

The problem with sloppy work is that the supply FAR EXCEEDS the demand

 

[GregLocock]

Australia's plan. It is non nuclear. We need to build 30 GW of nat gas, and spend $8T by 2060. Current GDP is $1.5T, so every year for 37 years we need to spend 14% of GDP on the transition. We also need to employ about 5% of the workforce on it.

For context we find it hard to spend 2% of GDP on defence.

Quite how they keep their faces straight I am not sure.

I thought the Labor Party target was 2050. Chris Bowen needs a new career, possibly as a used car salesman. Or a commodian.

 

[rb1957]

and Oz'll buy/build a bunch of nuke subs, and find and train the 100s of crew required.

Oh, and how does natural gas count as "carbon neutral" (unless it's prized politician "gas") ?

not at all natural and not in short supply.

UK national grid,

https://www.nationalgrideso.com/document/283101/download

Unfortunately it s 224 pages long. Here's the cheery picked version which i will attempt to read

https://www.nationalgrideso.com/document/283056/download

4 scenarios 3 get somewhere close to net zero in 2050. Huge requirement for hydrogen made by steam reforming, and then carbon capture the resulting CO2. This incredibly inefficient approach means that nat gas consumption doesn't fall by much, and a fair bit of the CO2 escapes. CCS has not been shown to work on a long term industrial scale (I think)

[rb1957]

and that'd be net zero from power generation (since its the national grid talking) ...

where's that pie chart showing sources of CO2 ?

[btrueblood]

I thought it was total CO2, as it talks about land-use and "other" CO2 sources (which I imagine includes iron/steel production and cement production?). It does seem like it's harder to do without nukes.

 

[rb1957]

what does this mean ?

is it saying that we're going to 1/2 our total energy demand ? "surely" that ludicrous (or even ludacris ?) ??

"Hoffen wir mal, dass alles gut geht !"
General Paulus, Nov 1942, outside Stalingrad after the launch of Operation Uranus.

 

[btrueblood]

It does seem ludicrous...unless they figure the cost/price of energy rises, and consumers "stay home and sweat"?

 

[rb1957]

and this is total energy (not per capita) ... what's the population increase over the next 30 years ... another 1 billion, 2 ?

but price is the main motivator ... higher prices mean more efficient (and more expensive) devices.

but why is "natural gas" such a "green" fuel ? combust it, does it not produce CO2 ? ok, maybe less CO2 per joule but still. And what sort of reserves do we have ? More than gasoline ? Sounds like a report the "natural gas" marketing board would put out.

[GregLocock]

It's roughly half the CO2/kWh of coal, and is the main reason why the USA's CO2 footprint is reducing. That transition is drawing to a close. Reserves seem to be enormous, 50 yers confirmed and more to come.

[rb1957]

1/2 of coal still seems a long way from zero ! But it could be a tolerable middle ground ... reduce the amount of CO2 whatever it is doing to the environment, at a reasonable cost, and keep the lights on.

Would've thought then that it'd be a case of natural gas as an interim measure, whilst we build more nukes.

This could get interesting... the province of Alberta vs. Turdeau...

"Alberta Premier Danielle Smith said she is “disappointed” in the federal government’s proposals for net-zero mandates and oil and gas production cuts.

In a statement on Saturday, Smith called the proposed mandates “unconstitutional” and “extremely harmful” to Alberta’s and Canada’s economies.

This comes after federal Environmental Minister Steven Guilbeault announced he will be publishing policy guidelines that will dictate the circumstances for the flow of future federal investment to Canadian oil and gas firms."

Sounds lire Premier Smith knows when a ‘mandate’ is impossible to comply with.
