.. will yield hydrogen that’s the same price as diesel by 2030 yet with a well-to-wheel supply chain that pumps out 75 per cent less CO2. By 2050, the hydrogen infrastructure from production through to user could yield zero net emissions... ML1...diesel!! about time they banned that stuff from all but heavy commercial vehicals...it's healthier to smoke a cigarette than it is to breath in diesel fumes... now a lot of people don't know this, time they did!! ____________ The Kite Fliers -------------------- Kite fliers: An imaginary club of solo members, those who don't yet belong to a formal team so "fly their own kites" - as the saying goes. | |

By 2050, the hydrogen infrastructure from production through to user could yield zero net emissions... ========================================================== bio diesel has very low sulfur and being renewable sequesters as much co2 as it generates, hemp seed is a very good source. pity we can't grow it in the states. ____________ | |

Slowly moving ahead: ======================================================================== while all of what you say is true it leaves out that hydrogen has to be made. this means either cheap electric power or processing from natural gas. with phase 4 nuclear cheap power could be possible, processing from natural gas produces greenhouse gases to. hydrogen is what you do when you have an excess of cheap electricity. as no hydrogen wells exist. ____________ | |

hydrogen is what you do when you have an excess of cheap electricity. Ideal for storage when there is excess wind/wave/tidal/solar electrical power... as no hydrogen wells exist. Which is what oil and gas wells are... There is a simple process for breaking the hydrogen out of the hydrocarbons at or near the well. The CO2 produced can then be pumped back underground to keep the well pressured and productive. The same strata that has held the oil and gas in place for millennia should also be suitable for keeping the CO2 trapped for further millennia...

An interesting twist to the power equation: | |
| ID: 1334783 · | |
hydrogen is what you do when you have an excess of cheap electricity. For long term storage it needs to be changed back to base carbon, and then it will store underground. Which could potentially be the equal of coal for the future. And yes that would be energy intensive.. thus the myth of "clean coal". ____________ Janice | |

One trend in the right direction, despite the politics: Ah, Guardian says that Bloomberg says that report of ... quote someone, quoting someone, quoting someone, quoting someone. We all know the game of telephone. Try a little truth. US carbon emissions continue to fall as production continues to be off-shored. Question is from a planet wide perspective is building it in China with dirty power, slave labor and shipping it across the ocean cleaner than building it in the USA? We know it costs less. We know it looks good on paper for US emissions. But planet wide? ____________ | |

Now, how much warming is acceptable? Zero? This just isn't making sense. I know you meant something, but zero is already impossible. Unless you mean that even with a population of 2 they can't start a fire to keep themselves warm at night. I'm wondering if you meant, no additional. That also isn't really possible. Enough CO2 has already been emitted to continue the raise for at least half a century even with the assumption there are no more humans on the planet. If you meant for the world to instantly stop producing CO2 emissions, then you are far to idealistic. Assuming that reduction in population growth is going to be a required part of the solution ... A very minor step which isn't enough. O/T I thought the last of those laws outlawing it were struck by SCOTUS and the last I checked a pack of condoms wasn't prohibitively expensive. Considering the hegemony of the US, do you have a better plan? Assuming that some reduction in the rate of industrialization is going to be part of the solution ... That is likely going to cost a lot of money. How is a non-industrialized country going to pay for it? Don't forget the industrialized world is already operating under austerity. As to the US, if you want to immediately shut all those non-clean energy things, then someone is going to have to pay the owner to shut it, and build a clean energy replacement. Where is that money coming from? We need ideas and plans on things which can actually be implemented given the economic and political realities that exist today. Pipe dreams need not apply. ____________ | |

Gary, if the warmers are correct, and I think they are, the problem will solve it's self and neither of us will be around to see the results. We will deindustialize as we know it or become Venus like. | |

Gary, if the warmers are correct, and I think they are, the problem will solve it's self and neither of us will be around to see the results. We will deindustialize as we know it or become Venus like. Are you saying there is no possibility of an economically feasible and politically feasible solution? That does leave open dictatorially imposed solutions or the actions of insane mad men, absent some natural global epidemic. ____________ | |

Gary, if the warmers are correct, and I think they are, the problem will solve it's self and neither of us will be around to see the results. We will deindustialize as we know it or become Venus like. If we can move beyond inertia, we have the technology to move to a carbon neutral society. It is even possible to correct some of the damage to the oxygen producing systems(oceans/forests) that we are in the process of destroying. Lighting a fire is fine, if all the wood used is replanted and the oxygen absorbed back in equal amounts. So Zero is a very reasonable STARTING goal. We will not be there tomorrow, but it certainly is not impossible. Unless we keep digging up fossils as if there is no tomorrow. For then there would certainly be no tomorrow much too soon. ____________ Janice | |

So where did we get all our coal and oil and gas from?... So how does soil and humus accumulate?... Rather than spouting random FUD, can you give a useful article to back up your random rants? Sure is easy to try to smash all threads rather than to be positive and helpful and add to useful discussion... Try turning a new more helpful leaf please? Meanwhile, the rest of the world have a life and a future to live. Regards, Martin ____________ Mandriva Linux A user friendly OS! See new freedom Mageia2 The Future is what We make IT (GPLv3) | |

Lighting a fire is fine, if all the wood used is replanted and the oxygen absorbed back in equal amounts. So Zero is a very reasonable STARTING goal. I don't believe I said rot was 100% efficient in releasing the hydrocarbons in the plant matter. As we are able to find a forest floor it has to be rather efficient however or all the plant matter that didn't rot would pile up hundreds of feet deep. It is also the major source of nitrogen for the next generation of plant matter. You can't just collect the wood and use it elsewhere and expect to have a forest no matter how many seeds you plant. ____________ | |

Gary, if the warmers are correct, and I think they are, the problem will solve it's self and neither of us will be around to see the results. We will deindustialize as we know it or become Venus like. IMO the only thing which could work democratically is when clean energy is more cost effective than what most of the world's population is doing. ____________ | |

We will deindustialize as we know it or become Venus like. the same "cradle to the grave" responsibility applied to asbestos could be extended to fossil fuels. The new clean alternatives would instantly be far superior.LINK And capitalism could continue unabated. ____________ Janice | |
