“Beyond 25 years the real betting is hydrogen engines from which the only emission is a little water out of the exhaust.”
Where are you getting your hydrogen?
FDB would be in trouble if we ran out of the formula for ice.
Cambria your man has the wrong business model for his car. He’s putting on a brave face if he thinks he can make hydrogen safe and cost-effective to be produced centrally and tanked. There is just no need for that since hydrogen is wonderfully easy to produce.
Not only is hydrogen a wonderfully easy thing to produce it can be produced intermittently with solar and wind power or anything else. You see solar and wind aren’t really suited for adding to the grid. You can do it but its a big fat hassle and an expense.
And compressing hydrogen to a great degree to make it suitable for mass distribution is in itself a waste of energy. The best deal is to make the hydrogen at home yourself. Just make it at home. Anyone with a suburban house at least can do it. And if I invested in a solar and wind system to make hydrogen at my house I could one day bring it in as part of the leasing contract.
BMW has the right idea for building the car. It ought to be a diesel hydrogen hybrid. And with nuclear electricity everyone can make just enough hydrogen at home to get to work and back. Since that level of compression will be safe and cheap and no waste of energy at all.
For blokes who are renting, or who live in the smaller apartments, there ought to be one fellow at the corner shop who will produce hydrogen and have a self-service pay and swap situation at the front of his shop. The idea is just to swap your little hydrogen tank and enough compressed hydrogen to get to and from work for one quarter the price of the diesel. Its when you try and go for strong compression and carrying the hydrogen long distances. Thats when the costs add up.
If you were in Anatarctica you ought to be able to produce the hydrogen for out and back fishing trips with diesel backup. You ought to be able to do this continually with wind power.
Its in this limited way that hydrogen is the fuel of the future. Always for the out and back trip only. And for the hydrogen to be manufactured locally. I mean HYPER-LOCALLY. If not in your house, then at least on your street. Its simply not suitable for centralised manufacture. Hydrogen is not suitable for tankers of hydrogen distributing it to the service station. And it is in precisely this way also that wind and solar power can play a part. Not for the grid, except where desert heliostats are concerned. Desert heliostats work in with peak demand electricity. But normal solar is feeble in this regard and can become so much more effective for intermittent production of hydrogen just for commuting. Wind promoters say that wind is fine with the grid but this is bullshit. It requires too much investment in “spinning” power. Like gas stations that can be cranked up quickly. This sort of extra gear. Apart from heliostats, wind and solar are a hassle for the grid. Wind power is usually in remote farm areas. But this is grand stuff for the intermittent production of ammonia and for the production of as much low-compression hydrogen as can be used locally. But not transported far and wide.
Another magnificent by-product is all the pure oxygen produced which will be incredibly helpful in aquaculture. As we all should know by now (he says sternly) overfishing is a real problem, and one which can and must be solved by taking aquaculture out of the tax system and by getting our homesteading of small ocean properties right. If we can get people producing hydrogen domestically or semi-domestically they could be selling tanks of pure oxygen also. The rapid expansion of aquaculture and the provision of all this pure oxygen, is a precurser also for accessing the holy grail of all hydro-carbons. That is the oceans methyl-clathrates. We have a potentially grand future and vision of the end of poverty and lush nature existing with and surrounding great bejewelled cities of incredible opulence and opportunity for all. But we have to take it. We must have the WILL and the leadership for such a future.
All it takes is this conceptual shift and we can have most of our consumer transport, in practice, running on hydrogen. We still need the big diesel trucks. We still need the big diesel ships. And we still need the nuclear energy and liquified coal. But getting most commuting on hydrogen. Well surely thats a good thing right?
One bloke on your street may be able to pipe hydrogen around at low pressure, for on the spot water and house heating and for the blokes who did not have the home production for their care. And that would work too. But always with hydrogen the concept must be hyper-local production. And low levels of compression.
