JAKARTA (AFP) –
Les négociations sur le réchauffement climatique cette semaine à
Bangkok s'inscrivent dans un contexte de critiques sévères contre les
biocarburants, qui ne sont plus désormais considérés comme une
solution miracle.
La combustion d'un carburant issu de la canne à sucre, du maïs ou du
palmier à huile est plus propre que celle d'un carburant fossile.
Mais les experts assurent que la demande en biocarburants entraîne des
effets fâcheux pour l'économie et la sécurité alimentaire mondiales, et
pourrait finalement causer davantage de mal que de bien à
l'environnement.

"It is widely understood that as populations and
economies grow global demand for energy will
increase, but the hard truth is that energy demand is
accelerating.
Under a business-as-usual scenario worldwide
energy demand is estimated to grow by 60% over
today's levels.
Demand for energy in China and India alone is
expected to grow at over 3.4% per annum to exceed
5300 million tonnes of oil equivalent by 2030."
"If provided by an energy system similar to
today's, that is to say largely using energy from
fossil fuels, carbon dioxide emissions can be
expected to exceed 14.7 billion tonnes by 2030, an
increase of fifty five percent above current levels.
This would spell imminent disaster for mankind."
"We believe that coal use will increase under any
foreseeable scenario because it is cheap and abundant.
Coal can provide usable energy at a cost of between $1
and $2 per MMBtu compared to $6 to $12 per MMBtu for
oil and natural gas. Moreover, coal resources are
distributed in regions of the world other than the Persian
Gulf, the unstable region that contains the largest
reserves of oil and gas."
"In particular the United States, China and India have
immense coal reserves. For them, as well as for importers
of coal in Europe and East Asia, economics and security
of supply are significant incentives for the continuing use
of coal. Carbon-free technologies, chiefly nuclear and
renewable energy for electricity, will also play an
important role in a carbon-constrained world, but absent a
technological breakthrough that we do not foresee, coal,
in significant quantities, will remain indispensable."
GM awards battery development contracts for Volt : Detroit, June 5 2007 (Reuters) - General Motors Corp. said on Tuesday that it had awarded two advanced battery development contracts for work on its electric-driven Chevrolet Volt car.A division of Germany's Continental AG and Compact Power Inc., a unit of South Korea-based LG Chem Ltd. won the contracts to develop the next-generation lithium-ion batteries for the Volt.
GM has said it was aiming to build the mass-market Volt by 2010 if it makes a battery pack to drive the vehicle cheaply enough and ensure its safe operation......
The push to develop environmentally friendly cars is an attempt by GM to distance itself from its close association with gas-guzzling sport utility vehicles, a reputation executives say has hampered its sales in some markets.
Once the media have convinced the general public that
hydrogen is the key to our energy future, no politician will
dare to claim the opposite.
Search Google for:
"Hydrogen sustainable transport" : 2 470 000 web pages
"Hydrogen inefficient transport" : 511 000 web pages.
How many press articles ask the question where this
marvellous fuel came from, and how much energy was
consumed (elsewhere) to produce it ?
"In a culture like ours, long accustomed to
splitting and dividing all things as a means of
control, it is sometimes a bit of a shock to be
reminded that, in operational and practical fact,
the medium is the message."
Marshall McLuhan,
University of Toronto, 1964
Four months later, on May 31, 1807, Emperor
Napoleon granted a 15 year patent to Isaac
François de Rivaz, citizen of the Republic of
Valais, for his discovery of the hydrogen-fuelled
Internal Combustion engine. The decree was
published in the October 1807 issue of the
"Bulletin des Lois de l'Empire Français".
For a brief historical introduction, please refer to the
hydrogen page of www.aecono.com. Many thanks to
the personnel of the Archives de l'Etat du Valais, in
Sion, who kindly provided numerical copies of the
1807 patent granted to Isaac de Rivaz, a remarkable
personality who more than 200 years ago invented
the hydrogen-fuelled internal combustion engine.
In 1789 Napoleon was elected member of the French Academy of Sciences
In 1799, he staged a coup d'état and became First Consul of the French Republic
In 1801 he was appointed President of the French Academy of Sciences
In 1803 he became Mediator of the Swiss Republic
In 1804 he crowned himself Emperor of the French
In 1805 he was crowned King of Italy

Any analysis of the hydrogen-vehicle concept must take into account the steps necessary to make the hydrogen and then get it into the fuel tank. And any comparison between hydrogen vehicles and other existing and potential technologies must include all steps in the technology, a process called well-to-wheel analysis.

ABSTRACT : The establishment of a sustainable energy future is one of the most pressing tasks of mankind. With the exhaustion of fossil resources the energy economy will change from a chemical to an electrical base. This transition is one of physics, not one of politics. It must be based on proven technology and existing engineering experience. The transition process will take many years and should start soon. Unfortunately, politics seems to listen to the advice of visionaries and lobby groups.

As access to oil and natural gas becomes more difficult
and costly, hydrogen will increasingly be produced by
gasification of coal under the form of syngas (a mixture of
hydrogen and CO) which is burned in a gas turbine to
drive an electricity generator. Such IGCC (Integrated
Gasification Combined Cycle) technology can also be
fuelled by asphalt, refinery waste or petroleum coke. The
syngas can also be converted by Fisher-Tropsch
technology to produce synthetic high-quality diesel fuel,
naphtha, LPG and methanol. The methanol can be used
as base chemical, it can power fuel cell vehicles, or it can
be upgraded to high-octane gasoline.
Coal-based power generation and fuel synthesis,
however, generate large amounts of CO2, and are
sustainable only if the carbon dioxide is efficiently
captured and sequestered. Industrial sites that integrate
coal gasification, power generation and the production of
syngas-derived chemicals with reliable sequestration of
CO2 will provide opportunities for buffering electric
power requirements through large-scale storage of
hydrogen. Such storage facilities may also serve to fuel
buses and other transportation vehicles for which the low
energy to volume ratio of hydrogen is not as serious a
problem as for private cars.
The British chemical concern ICI stores hydrogen in three
brine compensated salt caverns in Teeside, England. The
hydrogen is stored at pressures up to 50 bar in these up to
366 m deep caverns. From 1957 until 1974, GAZ DE
FRANCE stored towngas with a 50% hydrogen content
without problem in a 330 Mio. m3 aquifer storage. This
underground hydrogen storage method is about two
orders of magnitude cheaper than tank storage.

Madrid, Spain; partners are Air Liquide, Gaz Natural, Repsol YPF and EMT Madrid; hydrogen is produced onsite from natural gas by a Carbotech compact reformer, H2 back-up supply is provided by CGH2 tube trailers from chemical by-product generation, This is the first CUTE station to become operative by APR2003 (http://www.h2cars.de/filling/h2fueling.html)
In addition, safety precautions required by the
characteristics of hydrogen (low ignition energy, broad
flammability range, risk of destructive shock-wave
detonation when confined) will be more reliably mastered
in an industrial site than at a highway gas station.
Preparing a possible future for hydrogen as an energy
carrier, I would argue, does not require highway filling
stations, but technology for large-scale sequestration of
CO2, development of industrial fuel cells and efficient
electrolysers for power buffering, and large-scale, safe
storage of hydrogen that preferably avoids energy-
intensive liquefaction.
