2021 Climate Change

So i really see no reason for us to have moved so hard on wind, its sure as hell not like we get cheap power out of it, the KWH prize here is top 3 in the world.

Denmark should be getting cheap power out of it, even if the people don't!

For the UK, wind power is by far the cheapest source of power.

Due to rising fossil gas prices, the cost of producing electricity from existing fossil gas power plants in the UK – around £82/MWh as of 30 June - is now more than double the cost of electricity from new onshore wind installations - £38/MWh – and significantly above the £57/MWh the UK government estimates for offshore wind deployed in 2025.

Even cheaper in Spain:

In Spain, the costs of generating electricity from existing fossil gas and hard coal plants are triple those for new onshore wind (€31.7/MWh) and double those for new solar PV (€39/MWh).

Really? China is the 14th most polluted nation in the world versus the US at 84th. Definitely not the leadership I'd choose.


Both Australia and Canada are ranked better than the UK.

We need China to show leadership on CO2 reduction because it is currently the leader on CO2 emissions, it emits the most and is still increasing emissions. Until it starts reducing emissions, any reductions the UK makes, even if we go to zero, will be more than wiped out by China's increasing emissions. They have commited to reductions by 2050, and do have the most wind power and most solar power of any nation, but that does not seem to be fast enough considering they are the main polluter. USA is the second most CO2 emitting nation, but it is not currently increasing its emissions and nobody is listening to USA at the moment anyway, so it can't show leadership!

Australia and Canada are rated very very poorly on climate change, see post #1, they may be doing well on particulates, but that is mainly because they are both very big with low population density and have the whole of the Southern Oceans/Pacific respectively to dilute the pollution!

Americans better watch out, or the Danes will pass them on this too ( tornadoes )

It seem these are now a common occurrence with 1 confirmed last year, and at least 2 in the past few days.
Fortunately these are on the bottom range of the EF scale, but still enough to trash things and throw stuff around.

One of the tornadoes yesterday was on the ground for a good mile.

I think it may be a while until the Danish catch up to the US on tornado count.

Hehe yeah even pr capita we will have to ramp up big time.

SSAB Oxelösund has delivered the world’s first 100% fossil-free steel using HYBRIT technology, that uses hydrogen instead of coal and coke, to Volvo Group, the company has said today (August 18).

HYBRIT, established by SSAB, LKAB and Vattenfall, is producing carbon-free steel to decarbonise the steelmaking industry whilst also providing green steel to manufacturers.

Using HYBRIT technology, SSAB has the potential to reduce Sweden’s total carbon dioxide emissions by approximately 10% and Finland’s by approximately 7%.

Martin Lindqvist, President and CEO of SSAB, said, “The first fossil-free steel in the world is not only a breakthrough for SSAB, it represents proof that it’s possible to make the transition and significantly reduce the global carbon footprint of the steel industry. We hope that this will inspire others to also want to speed up the green transition.”

"Clean energy pioneer Stiesdal starts up 'stepping stone' CO2-negative green fuel plant"

Hope they don't remove too much CO2 from the atmosphere, or we will be having another ice age

The end product of Stiesdal’s SkyClean process will be a fuel that is chemically identical to the A-1 jet fuel currently used by airlines but produced in a process that actually removes carbon from the atmosphere. This means the more SkyClean fuel is burned, the more CO2 is removed from the air.

Experts from the DTU and Aarhus University have calculated that the agriculture industry can halve its greenhouse gas emissions using the SkyClean technology.

In simple terms, a pyrolysis oven is used to heat agricultural waste in the absence of oxygen, converting the biomass into three components: biooil, syngas and biochar. The biooil and syngas are then combined with green hydrogen – produced by using renewable energy to split water molecules into hydrogen and oxygen – to create biomethanol, which is then synthesised into aviation fuel.

Hehe yeah too much is not always a good thing.
There seem to be a lot of these air scrubbers, but i am not aware of their actual performance, but the way things are going something like that probably have to be deployed, so someone i do think stand to make a pretty penny / create some jobs.

Again this is not something that is patented i think, so anyone could probably just copy it.
My constant frustration government constantly saying what we Danes must live off in the future is knowledge, but i do not really see any increase in Danish intellectual property, so i cant trust the people who say things like that.

It would be nice that in the future people of the world would fly and drive on Danish Sh.. instead of oil

There is of course the "Danish oil" for treatment of wood, but you cant really drive on that, but if we put a few of those gismos in our parliament the BS they let out in there can probably power most of the western world.

I don't have much hope for most of "these air scrubbers" being successful, but this technology produces a valuable product in the form of CO2 negative standard aviation fuel, which is hard to beat for intercontinental travel, so likely to stay profitable, and it stores a significant amount of CO2 as biochar, which appears to be a form that can actually be stored safely and securely for milenium. and it helps the agricultural sector dispose of its waste without CO2 emissions. Looks very promising. Not sure if they can manage to enforce patents on it worldwide to make a fortune though, and it will be easy to copy once it is seen to be successful, so they can't sell expertise.

 

[kamkar]

yeah making a product that can be used again VS just make a product you pump into the ground or what ever people want to do with captured Co2

 

[kamkar]

If the world could do something about "cow farts" that is actually belching, then the world would indeed be a better place, and vegans would loose one of their favorite arguments.
Industrial animal farming as we Danes excel in, is quite expensive for the environment.

 

[Dashmellow]

The SkyClean technology sounds very promising but how much energy needs to be expended for the process and where does that energy come from? Perhaps they can use the fuels they create to power their plants but one way or another this will require lots of energy for this process to work. Pyrolysis is the process used to create coke from coal for example, used in iron ore smelting. They are talking about a 20MW "demo" plant.

 

[Nigel]

but how much energy needs to be expended for the process and where does that energy come from?

Lots of energy, sourced from the green hydrogen, which in Denmark will come from wind turbines, but could be solar nearer the equator. I assume some power comes from the agricultural waste too, it certainly contains power, but maybe only enough to fuel the process, thus making the hydrogen to methanol conversion effectively 100% efficient?

Using lots of energy is not a big issue since most of it ends up in the aviation fuel where it is useful. OK, it is not 100% efficient, but most of these carbon capture technologies use energy and don't produce anything useful! The real question is the cost of the aviation fuel compared to other methods of making aviation fuel which may be a bit cheaper but which don't store as much carbon, and how much they can effectively make from the carbon storage, for which they will presumably be able to sell carbon offset credits which can subsidise the aviation fuel.

Early stages yet, some of these technologies need to succeed and this one is looking promising.

Yes, the cost is a big question. Ultimately, the efficiency will be a big question too! So often, these promising sounding startups sound great on paper and in their initial prototype phases but then don't end up coming to fruition due to some insurmountable fly in the ointment that wasn't foreseen or sometimes not revealed in the first place thinking they would eventually figure it out.

 

[Nigel]

Ultimately, the efficiency will be a big question too!

From the point of view of climate change, the efficiency does not matter. Since it is CO2 negative, less efficient is better for CO2 emissions!
The efficiency only affects the cost of production, which of course affects its competitiveness.

If it is powered by wind then less efficiency means more wind turbines, but wind turbines will soon be carbon neutral, so that is not a problem other than to its competitiveness.

I don't buy your thinking. It needs to be efficient for it to be a viable alternative, even if it does suck up CO2. Unfortunately, Pollyanna thinking only will get you so far in a world subsumed by suicide capitalism. Just look at what has happened to and continues to happen to the Brazilian rain forests under Jair Bolsonaro.

Maersk shipping, have committed to this E - methanol ( that company pollute with their ships as the whole of Denmark do )
But so far it is small amounts of fuel they can get their hands on generated that way ( a drop in the massive crude / MGO fuel tanks on their ships )

Even if we Danes went all in on this with our power to X efforts, you cant have a global shipping company that can only refuel at home in Denmark.
And they probably still need more fuel that we can generate here on the best of days and with a infrastructure we will not have anytime soon ( super massive wind energy parks and energy islands out in the sea )
