My friend Sam the CEO (who is an oilman) sent me the following:
The bl**dy K----ri carbon capture project is so st_p_d.
W@$ting Malaysian citizens' money to the tune of RM4.5 Billion.
Sinking f--king money into a sh_th*le.
Climate change my @$$.
We cannot even affect 1% of the world's carbon output.
Why is a 3rd world country doing this sh_t?
My comments :
They say they have no money. So they are down sizing, right sizing, capsizing etc.
Yet they are throwing RM4.5 Billion into a project which is totally unnecessary, unproven, super highly risky and really quite useless.
They call it Deep Sea Carbon Capture.
I asked Chat GPT what is Deep Sea Carbon Capture and it said the following (my comments in blue).
Deep sea carbon capture is a method of removing carbon dioxide (CO₂) from the atmosphere and storing it in the ocean's depths. This is often referred to as ocean carbon sequestration. There are different approaches to deep-sea carbon capture, but the main goal is to reduce atmospheric CO₂ levels and mitigate climate change. Here's a breakdown of how it works:
1. Carbon Capture (CO₂ Removal from the Air)
The first step involves capturing CO₂ from the atmosphere. This can be done using Direct Air Capture (DAC) technology, which filters CO₂ from ambient air, or through bioenergy with carbon capture and storage (BECCS), which involves capturing CO₂ from biomass-based energy production.
(OSTB : I cannot believe this. Removing CO2 from the air? Why not remove the salt from the sea? If the earth is warming up, can they create a huge space umbrella and block off the sunlight? You know, to create some shade?)
2. Transporting CO₂
Once the CO₂ is captured, it needs to be transported to the ocean. This is typically done by compressing the gas into a liquid form and then transporting it via pipelines or ships to locations where it can be injected into the ocean. The transport process must ensure the CO₂ is kept under high pressure to remain in its liquid state.
3. Injection into the Deep Ocean
The CO₂ is then injected into the ocean at a significant depth, typically between 1,000 to 3,000 meters (about 3,300 to 10,000 feet). This depth is important for several reasons:
Pressure and Temperature: At these depths, the high pressure and low temperatures allow the CO₂ to stay in a liquid or supercritical state, reducing the risk of it escaping back to the atmosphere.
Lack of Mixing: The deep ocean is less likely to have strong currents that can bring the CO₂ back to the surface, so it stays trapped in the deep ocean layers.
(OSTB : The freezing point of sea water (salt water) is minus 2 degrees Celsius. The natural temperature of the coldest sea water cannot go below that. At 10,000 feet depth, the temperature of seawater is between 1 degree Celsius to 4 degrees Celsius (according to Chat GPT).
The liquefaction temperature to liquify carbon dioxide (CO2) is minus 78 degrees Celsius (at 1 atm). Slightly warmer (minus 56 degrees Celsius) at 7 atm (Chat GPT again).
If you inject liquid CO2 at minus 78 Celcius or minus 56 Celsius into seawater at minus 2 Celsius, the CO2 is going to start boiling, bubbling up to the surface and evaporating back into the air.
What do they mean by is less likely' ? No one knows for sure?)
4. Long-Term Storage
Once injected into the deep ocean, the CO₂ is typically stored in the deep water columns or is deposited in geological formations on the ocean floor, such as undersea basins or depleted oil fields. The oceans are naturally capable of absorbing and storing CO₂ over long periods of time, though some studies have raised concerns about the long-term effects on marine ecosystems.
5. Chemical Reactions
In some cases, the CO₂ can react with minerals in the ocean to form stable compounds, such as carbonates. These reactions are a form of mineral carbonation and help to permanently lock away the carbon.
Challenges and Concerns:
While deep-sea carbon capture could theoretically be an effective tool for reducing CO₂ in the atmosphere, there are challenges and risks:
Marine Ecosystem Impact: Injecting CO₂ into the ocean could change the chemistry of the water, leading to ocean acidification and potentially harming marine life.
Leakage Risk: There’s a concern that the CO₂ could eventually leak back into the atmosphere if the storage is not secure enough.
Costs and Infrastructure: The technology, transportation, and infrastructure needed to implement this method on a large scale are currently expensive and not yet fully developed.
Overall, deep-sea carbon capture is still in the experimental or early development phase, and further research is needed to fully understand its potential effectiveness and ecological impacts.
My Comments : They are going to spend RM4.5 Billion of our money on "deep-sea carbon capture which is still in the experimental or early development phase" ?
This is exactly what Dr Mahathir did with that gas reduction method to smelt iron ore at Perwaja. It was an experimental method and it did not work. But at least the Japanese (Mitsubishi??) paid a compensation of over RM800 million (big, big money at that time).
If this RM4.5 billion pumpkin does not work, who is going to compensate us for RM4.5 billion?
No wonder that Missy went to Davos.
Do listen to President Trump. He has no time for hocus pocus, save the planet, carbon capture or the global warming crap.
