Hydrogen fuel source ?

Question

I'm writing a persuasive speech on why hydrogen would make a good alternative energy source, but I'm stuck. I'm not sure how to say how hydrogen is efficent. any ideas ?

this is the first sentence of it :

Another myth is that hydrogen will be inefficient. Hydrogen is, in fact, very efficient.

Answer 1

Sorry, hydrogen is very inefficient because the input of energy needed to get pure hydrogen from H2O is far greater than the output when hydrogen is burned.

Answer 2

The energy that it takes to make water hydrogen out of water is very inefficient. It may take 10 times the electricity to produce hydrogen as to how much power U could generate.

Answer 3

Bad news. H2 isn't a fuel  source. It's an energy transfer method, and not a good one for transportation.

But for the sake of argument, you could focus on the chemical reaction itself, and the use of fuel cells. Just don't mention storage or infrastructure.

Answer 4

Here's a great page about Hydrogen fueled vehicles:

Answer 5

Hydrogen has more combustion power than gasoline. A cars own alternator could produce what  electricity is needed to produce hydrogen. And the exhaust left from the burning of hydrogen  is water, that can run right back to the main water(fuel) tank. Can you imagine never having to fuel your car. A photovoltaic could be a back up carging system. The whole cars' skin could be made of that flexible PV stuff, seen on eco-tech on the science channel on direct tv. More and more things not thought possible before, is starting to happen all over the world. Everything has to do with how  things are being done. Everything is possible.

Answer 6

Maybe you should read some ( if not all) of these books.

You can also mention how Iceland plans to be the first Hydrogen economy, with all of their private automobiles, fishing boats, and public transportation running on hydrogen fuel, Iceland began opening stations in 2003.  Also talk about how  Since the turn of the millennium, filling stations offering hydrogen have been opening worldwide. Germany & Japan have many Hydrogen Stations, and that British Columbia, Canada is building a seven node hydrogen refueling station network from Victoria to Whistler timed to coincide with the 2010 Winter Olympic Games. Hynor, Norway's first hydrogen fueling station was opened in February, 2007, and. the UK has opened its first hydrogen filling station at the University of Birmingham. Stations in California opened by the California Fuel Cell Partnership, and under Governor Arnold Schwarzenegger's California Hydrogen Highway program. In 2000, Ford and Air Products opened the first hydrogen station in North America in Dearborn, MI. Proton Energy Systems and Northern Power, both wholly owned subsidiaries of Distributed Energy Systems, were contracted by EVermont to build an advanced demonstration hydrogen fueling station in Burlington, VT. The project was partially funded through the U.S. Department of Energy’s Hydrogen Program.  You can then go into how  It is estimated that more than a thousand hydrogen-powered vehicles were produced in Germany before the end of the World War II, or that  major car companies such as DaimlerChrysler and General Motors Corp, are investing in the more efficient hydrogen fuel cells instead.Ford Motor Company is investing in both fuel cell and hydrogen internal combustion engine research. BMW — The BMW Hydrogen 7 is powered by a dual-fuel Internal Combustion Engine and with an Auxiliary power based on UTC Power fuel cell technology. The BMW H2R speed record car is also powered by an ICE. Both models use Liquid Hydrogen as fuel. Daimler AG — F-Cell, a hydrogen fuel cell vehicle based on the Mercedes-Benz A-Class. Fiat - Panda hydrogen, a hydrogen fuel cell vehicle utilizing Nuvera's Andromeda fuel cell stack Ford Motor Company – Focus FCV, a hydrogen fuel cell modification of the Ford Focus, and E-350 buses, which began being leased in late 2006. General Motors — multiple models of fuel cell vehicles including the Hy-wire and the HydroGen3 Honda – currently experimenting with a variety of alternative fuels and fuel cells with experimental vehicles based on the Honda EV Plus, most notable the Honda FCX, powered by a front-mounted 80 kW AC electric motor, with 20 kW pancake motors providing supplemental power to the rear wheels. Electrical energy is provided by a 100 kW hydrogen fuel cell, with regenerative braking energy stored in ultracapacitors. The first production version of the FCX, dubbed the FCX Clarity, was announced at the 2007 Greater Los Angeles Auto Show. The vehicle is expected to be available in limited numbers for lease only in the Los Angeles area. mid-2008. In November 2007, Honda announced its new Home Energy Station IV that uses steam reforming of natural gas to derive hydrogen from both the steam and natural gas in equal parts. The Home Energy Station IV is 75-percent smaller than older units and provides hydrogen for a car as well as heat and electricity for the home. Hyundai — Tucson FCEV, based on UTC Power fuel cell technology Mazda - RX-8, with a dual-fuel (hydrogen or gasoline) rotary-engine Mazda - Mazda Premacy Hydrogen RE Hybrid, with a dual-fuel (hydrogen or gasoline) rotary-engine Nissan — X-TRAIL FCV, based on UTC Power fuel cell technology. Morgan Motor Company – LIFEcar, a performance-oriented hydrogen fuel cell vehicle with the aid of several other British companies Toyota – The Toyota Highlander FCHV and FCHV-BUS are currently under development and in active testing. In November 2007, ten new hydrogen powered Prius cars were delivered to three companies in Iceland by VISTORKA, a shareholder in Icelandic New Energy.Volkswagen also has hydrogen fuel cell cars in development. Mazda leased two dual-fuel RX-8s to commercial customers in Japan in early 2006, becoming the first manufacturer to put a hydrogen vehicle in customer hands. BMW also plans to release its first publicly available hydrogen vehicle in 2008, as does Honda. You can bring up that any Internal Combustion Engine (ICE) can be modified to run on Liquid Hydrogen.  How about the fact that Hydrogen is what sends the Space Shuttle into Orbit. The following companies modify automobiles to run on hydrogen:

AFVTech

Hydrogen Vehicle Systems

Intergalactic Hydrogen

The Hydrogen Car Company

Quantum Technologies converts new Toyota Priuses to run on hydrogen.

Other Uses of Hydrogen

Hydrogen is used extensively today to make ammonia, methanol, gasoline, heating oil, and rocket fuel. It is also used to make fertilizers, glass, refined metals, vitamins, cosmetics, semiconductor circuits, soaps, lubricants, cleaners, and even margarine and peanut butter.

Hydrogen can fuel today’s internal combustion engine vehicles. Hydrogen can fuel tomorrow’s fuel-cell vehicles.

Hydrogen can replace today’s natural gas for heating and cooling homes and powering hot water heaters. Existing wind and hydroelectric plants can produce hydrogen to store energy during off-peak hours. Hydrogen production from hydrocarbons can also produce carbon, which, made into carbon fiber, has ten times the strength of steel. With more research, this carbon could be used for automobile bodies and structural members. Sources of HydrogenHydrogen is now made from natural gas (methane), petroleum, coal, various chemical reactions, and from biomass (landfill waste, wastewater sludge, and livestock waste). It can also be made from water by electrolysis. Hydrogen can be made from renewable resources, such as wind or solar. Hydrogen is currently made primarily from natural gas (methane), which is non-renewable. Methane is a recycled fuel (and therefore renewable) when made by anaerobic digestion of biomass. Hydrogen production from hydrocarbons can also produce carbon, which in some forms has ten times the strength of steel. With some research this carbon could be used for automobile bodies and structural members.

With this you should be able to convince anyone.

Answer 7

Perhaps next time they could assign you to make a persuasive speech about why two plus two equals five.  That's about the same sort of argument you've been asked to make.  

You don't have the engineering background to make any pertinent points, nor should you be expected to.  Debate is for matters of law, ethics, religion, and politics.  It's not for technical matters that are properly be proven in the laboratory or by mathematics.  You can read this to whoever thought up this silly exercise.

Answer 8

hydrogen COULD be efficient if it is extracted through electrolysis of water in a clean renewable matter, such as geothermal, solar, or wind. (Like in Iceland and Denmark)

But then again it still wouldn't be as efficient as just using the electricity produced to power an electric car.

One way hydrogen can be efficient is to use algae to produce it organically.
