Ask yourself exactly how. Btw... You do know that from an energy perspective it would be better to burn NatGas in a hybrid rather than use NatGas to create hydrogen for use in a fuel cell.

In liquid form it gets much better but still not on par with fossil fuels and then you have the problem of long term storage. No matter how well you insulate the tank, you'll lose a substantial amount of fuel (=range) while you park your car at an airport for 2 weeks. Look at the most powerful and efficient rocket engines. What is their fuel? Hydrogen! Pound for pound it packs more energy than anything else. I do like the idea of hydrogen, but the storage and distribution are MAJOR obstacles. I am curious to see how the aviation industry, that is now trying out a transition to hydrogen, is going to tackle that problem. |

Interested in knowing where you got this and what it means.
Where does the other 70% go?

Let's assume the figure is correct. The system can only absorb so much.
This is why C02 levels have been increasing dramatically since the industrial revolution.

Oh I know, my buddies rock crawler runs on LPG. He likes it because he can never flood on extreme inclines or angles. But there is still spent gas coming out of the pipe, albeit much less. The conversion was easy and most motors can swap to this. But to be scared of the engineering needed to make hydrogen feasible is silly when it comes with the most acceptable byproduct. You know that Toyota did this already with the Mirai? You did nail it when you said it’s not known for performance but that’s what BMW and mostly all auto manufacturers do. They push the engineering into function. If it were my call……I’d like to stay with petrol because the sound and performance is amazing. Not to mention the motors are runnining cleaner and cleaner with each iteration. I guess all I’m getting at is that it could be done and will be done.

Hard to believe only 30% is absorbed and 70% isn't. I realize he said "today" but tomorrow will be another day of 30% absorbed and 70% that isn't. Seems far worse than I would have expected. Imagine someone that said that each day they burn 30% of the calories they take in each day. Still interested in hearing where this number came from.

The accumulation and what it means is at the center of the debate of course. Saying it is increasing means nothing really. Deciding on what is a proper or correct level in the atmosphere is just a guess. CO2 is good. It just depends on how you look at it. I plan on exhaling it for the rest of my life. To help the trees of course. Last edited by Efthreeoh; 09-14-2024 at 08:53 AM.. |

Neither say anything about automotive CO2 and both are talking about role forests play in the the total CO2 from burning fossil fuels.

No it won't because the amount of emissions continues to grow. This is why companies are working on sequestering carbon.

The terrestrial carbon sink (forest) consumes "about 30% of carbon emissions from burning fossil fuels" (read in the attachment to my previous post). NASA states "Forests and other land vegetation currently remove up to 30 percent of human carbon dioxide emissions" by photosynthesis (read in the attachment to my previous post). NOAA states about 31% of CO2 in the atmosphere is absorbed by the earth's oceans. The ocean can sequester CO2 for hundreds or even thousands of years. CO2 in the atmosphere is CO2, the source of the CO2 is immaterial to the discussion; all CO2 sources mix together in the atmosphere. So, add the terrestrial carbon sink with the ocean carbon sink and that's around 60% of automotive emissions are recycled by mother earth. 60% of the carbon emissions from electricity generation are also recycled by mother earth. Mother earth doesn't recycle the toxic chemicals in EV batteries. In fact, once EV battery recycling comes on line in significant capacity, that industry will produce additional carbon emissions because most recycling activities require energy for the recycling process. Believe the science. We need more forest, more oceans, and less cities.

As for the disposal problem, you are acting like CO2 is the only pollutant ICE is producing. Note the brown haze that hangs over most major cities that we breath in. Batteries, if recycled, disposed of properly I won't ingest any of it. As for the net result of batteries, there are ways to recyle most of the battery, there are ways to dispose of the waste properly. Plastics don't decay in a reasonable amount of time, neither does nuclear waste. No idea what you are proposing with the "we need more forest, more oceans, and less cities" --- We aren't getting more oceans, if everyone from the city left and went to the country it would be far worse for society.

Oceans absorb some but eventually it'll reduce the pH of saltwater which can have a negative impact on fish stocks. https://oceanservice.noaa.gov/facts/acidification.html
