This is fundamental chemistry and physics. No ranting and raving or spending campaign is going to change it.

The tools of biocommodity engineering are starting to mature, and this is where we need to put more resources.

But we don't have to wait - FFVs (Flexible Fuel Vehicles) are on the market today, thanks to tax incentives. People need to be made aware of this alternative. The problem? Outside of the midwest and corn based ethanol, it's hard to fuel up on fuel grade ethanol at the pump. More investment in building production facilities and developing distribution channels to the pump is needed for the several million FFVs already on the road, and a government-financed consumer awareness campaign would also go a long way to supporting this effort.

Electric assist makes a huge difference in the car's feel, especially for those who shun anything that won't pop off a light like a Roman candle.

    The Honda Dualnote concept car is an excellent example of this idea, the combustion engine charges an ultracapacitor while idling or braking. Said capacitor gives an extra umph (100hp worth) when accelerating. If you were to stick such a system on a high efficiency yet power deprived car like the TDI Lupo it'd make for a fair bit of go juice without expending a ton of gas juice. Citroën and Audi have shown that it is possible to make exceptionally clean burning Diesels which is promising for the Diesel-smells-like-poo opponents. Nissan's Gloria is making some great advancements using toroidal CVTs instead of conventional gearboxs.

    These sorts of advances lend well to designing a really badass Diesel hybrid. From conception to fruition Diesels are going to be far cheaper than any hydrogen powered car for the next several decades. Diesel fuel is much easier to store and transport than pure hydrogen, it is more robust than methanol, and with biodiesel is renewable and is only pumping the CO2 back into the environment that was used to grow it.

    Personally I don't believe that until oil runs out we'll ever wean ourselves from it: and given how big the reserves of oil producing states are, I don't believe it will run out for another several decades unfortunately...

  29. An H2 based economy will happen by pcb · · Score: 2, Insightful

    An H2 based economy will happen. There is absolutely no doubt about this. The general trend throughout history is to go from high carbon fuels to a zero-carbon fuel (wood -> coal -> oil -> gas -> H2). This transition will happen probably over the next 100 years. H2 will be piped into every home and used for both electrical energy (fuel cells) and heat (a furnace).

    The most important thing to remember about H2 is that it is NOT an energy source, but an 'energy storage' system. An H2 tank is basically an chemical battery (all batteries are chemical, but you know what I mean). H2 allows energy to be generated in one location (wind-mills on the prairies) and moved to another location (a car manufacturer in Toronto). Currently, generated electrical energy (wind, hydro, etc.) must be consumed at the same time. By converting it into H2 it allows the energy to be stored.

    The real question is not if it will happen, but how. There are two broad possibilities. One, the H2 will be distributed in a similar fashion as natural gas is today: Through pipelines that are controlled by state sanctioned monopolies (i.e. the Gas Company). There might be limited competition at the high volume end of things between large companies. These companies will control generation and distribution (and hence the price).

    The second model is much more democratic. The pipelines will be owned by the public (like most roads are today) and the mechanism of transmission will be operated by some body (public or otherwise); that is, they'll look after the physical infrastructure. Here's the kicker: the generation and sale of H2 will be open to anybody. Most people will still choose just to buy the H2 at the market price, but people will also be able to store H2 if they want. They will be able to purchase the H2 when the price is low (night), store it in tanks, and sell when the price is high (day). Very complex computer programs will be written to try maximize their profits. Furthermore, people with small wind-mills or solar cells will be able to sell the extra energy that they do not consume by generating H2 and selling it on the open market. Farmers on the prairies will be able to build windmills to generate H2 and supplement their incomes. In this model, the free market is in driving force for the price of H2, not monopolies.

    It is important to understand what is happening with H2 based economies because it is up to the people to ensure that the second model happens. Big oil/gas companies will oppose it every step of the way and try to maintain control. It will be interesting to see what happens.

  30. Biggest Problem with the Article by Henry+V+.009 · · Score: 4, Insightful

    Currently, the least expensive method is a process known as steam reforming, in which natural gas reacts chemically with steam to produce hydrogen and carbon dioxide, a greenhouse gas. Far preferable would be to use carbon-free resources like solar, wind, and hydropower to produce electricity for electrolysis, which splits water into hydrogen and oxygen. Hydrogen would make renewable energy practical, acting as a storage medium for the modest amounts of energy such resources produce. Wind power, especially, lends itself to this sort of use.

    And there's the rub. Even neglecting the astronomical capital costs, no one has concieved a renewable energy program that will fulfill our energy needs. Most hydrogen will have to be produced from natural gas. The rest will have to be produced using electricty generated by nuclear, fossil fuel, and hydroelectric plants. No renewable technology has yet been proposed that could possibly generate enough power to do this a bearable cost. Hence, our dependance on foreign oil remains.

  32. Hydrogen is a distraction. by cryptochrome · · Score: 4, Insightful

    People go on and on about the hydrogen future, but it's a mere distraction. Hydrogen will not replace oil, or coal, or gas. It may replace gasoline. Because hydrogen is an intermediate energy form - it's temporary storage between production/harvesting of energy and use of energy. And for all its supposed advantages, it's got a lot of faults. IMHO, diesel/biodiesel is a much more flexible and practical intermediate fuel - and if anyone could come up with a better battery, it would beat both.

    The real question is energy generation/production/harvesting. We need to stop shipping in oil and burning up coal and start harvesting it from renewable (AKA "effectively infinite") sources, particularly the ones with low environmental impact. That means solar, wind, microhydro, biodiesel, cellulositic ethanol, tidal and current turbines, and geothermal. We need on-site off-grid power generation. We need to distribute energy generation and storages so that we don't need delicate, wasteful shipping methods - be they the power grid or fuel trucks. And we need to stop letting everyone get away with building structures and devices that waste energy with wild abandon.

    Long story short - hydrogen may have potential, but it's being sold like snake oil and it's years away from reality. If we focused on simpler, proven technologies and put some real effort into some rather obvious fields of research (like high efficiency solar) we could have a working system in much shorter order.

    There is a major shortsight to a hydrogen economy not mentioned in Schwartz' article. I apologize if this has already been mentioned and I have been too lazy to scroll through the replies.

    Peter Schwartz neglects to mention something that is perhaps not immediately obvious - hydrogen is currently produced from petroleum. It is going to be extremely, extremely difficult to transition to a hydrogen economy while leaving petroleum behind. To do this is going to require a major advance in science - namely the development of an inorganic system for splitting water to produce hydrogen and oxygen. There have been many great minds working on this for years and currently the record for doing this is around 1% at best (based on the conversion of hydrogen from a single photon).

    Clearly, a hydrogen economy devoid of an intimate connecting with fossil fuels is not going to be a reality any time in the near future.

    The first way to begin easing the dependency on petroleum is to both decrease consumption and increase the efficiency of processes that consume energy. The first of these is obviously not a simple task. The second is. John Deutch (MIT) has argued that if all cars in the US were hybrid, we would reduce the daily consumption of petroleum by approximately 30% (I recall it would be around 3 million barrels/day vs 30 million). And this is just the start - think about all of the other technologies that could be improved by improving efficiency.

    My point is not to shoot down the article, but simply to note that the switch to a hydrogen economy is absolutely going to be connected to petroleum - there is currently no other way to produce hydrogen as efficiently (currently steam reforming hovers around 60-80% in terms of the yield).

    a) Where the energy is generally doesn't have good grid connections. For example, there is enough wave energy off the west coast of Scotland to run the entire UK, and enough wind to run about half the country. There are simply no Supergrid connections to the entire region. It would be very expensive and fairly difficult to build them. But we already have gas pipelines to supply the towns with natural gas.

    b) You can't regulate them by demand, as you can with fossil powered turbines. When the wind blows, you get electricity, regardless of whether you want it or not. The Grid can't store electricity - it has to produce exactly as much as is being used at any one time. Any imbalance is taken out of the kinetic energy in the spinning turbines, which leads to a.c. frequency fluctuations. Too much wind/wave/solar power feeding straight into the Grid would rapidly lead to desynchronisation.

    However, both these problems could be solved by using Hydrogen, as it's a simple method of storing energy, which could be piped ashore/around using existing natural gas pipelines and stored until needed (porosity issues aside).
