Last week NASA announced that it was putting the launch
of STS-107 - and future Shuttle missions - on hold after small cracks were discovered in
the flowliners within the plumbing that feeds liquid hydrogen (LH2) to the Space Shuttle
Main Engines (SSME). Cracks a fraction of an inch in size were discovered in LH2
flowliners in Shuttle Orbiters Discovery (OV-103) and Atlantis (OV-104). [see links below
for two NASA briefings on these cracks]. Cracks have also been found in a Shuttle
propulsion test structure. Orbiters Columbia (OV-102) and Endeavour (OV-105) have yet to
be examined.
An interesting concept currently being explored in
Germany is that of hydrogen-powered cars. Journalists were given an idea of how this
system works during a visit to the world's first public filling station for liquid and
gaseous hydrogen at Munich International Airport. In principle, the hydrogen engine is
nothing other than a machine that uses water for its fuel to eliminate the emission of
dangerous emissions. And what is more, many experts predict that in the long run fossil
energy resources will run out, so the alternative hydrogen is an ideal option.
UCA Assistant Professor of Chemistry Patrick
Desrochers shows off vials of substances that may someday be used to fuel hydrogen-powered
cars. He has authored several manuscripts and made formal presentations on research in
chemistry, particularly with the element nickel. Several works have cited his research
with nickel.
Oil companies can wrest the initiative from the green
lobby by making the clean fuels of the future from their own refineries, but they will
need to act quickly if they are to stay ahead of the game, a Shell executive said on
Friday. Hydrogen was likely to be a vital clean source of energy, Michiel Boersma, the
head of Shell's Global Solutions consultancy, told an industry conference. But he said
producing it through the solar-powered electrolysis of water, as green groups would like,
would remain costly and difficult for a long time. "While some environmentalists are
reluctant to admit it, the refining industry offers a number of very practical ways
forward on hydrogen. Refineries can convert fossil fuels to usable hydrogen by
gasification far cheaper than the solar model," Boersma said. "This would set
the ball rolling on hydrogen, build public acceptance and attract investments into
research."

Double World Record with the Solid Oxide Fuel Cell - Research Center Julich
(Germany)
Scientists at Research Centre Jülich (Germany) report an
important step forward in the international race to develop efficient high-temperature
fuel cells. A fuel cell stack put into operation in mid April consisting of just 40 single
planar cells delivered a power of 9.2 kilowatts at an average operating temperature of
850°C with hydrogen as the fuel gas. Operated with methane the stack still managed to
achieve 5.4 kilowatts. This is a new world record for a planar system both with respect to
power and also to the cell size of 20 x 20 centimetres. Fuel cells convert the chemical
energy of hydrogen directly into electricity. Solid oxide fuel cells (SOFCs) are of major
interest for stationary electricity and heat generation in power stations or buildings.
However, they also attract increasing attention for mobile applications. SOFCs promise
very high efficiencies for electricity generation and thus an economical and
environmentally friendly fuel utilization. Scientists at Research Centre Jülich are
working on advanced SOFCs with planar cells and thin electrolytes. Many experts predict
that this design will have a great market potential since systems with planar SOFCs
already achieve high efficiencies with small volumes and low operating temperatures. SOFC
research at Jülich is also being supported by the Federal Ministry of Economics and
Technology (BMWi).
Scientists from the Jülich Institute for Materials and Processes in
Energy Systems (IWV) and the Central Department of Technology (ZAT) first directly
operated the record-breaking stack of 40 single cells with hydrogen at an average
temperature of 850°C. This stack delivered a power of 9.2 kilowatts - more than twice
that of the best performance in the previous year. Furthermore, temperatures of less than
900°C are regarded as low in the world of high-temperature fuel cells. This is beneficial
for the lifetime of all materials and allows relatively cheap metallic materials to be
used. The scientists then adapted the stack to use methane as fuel gas, which is directly
converted into hydrogen in the cell. There is thus no need for a prior conversion step
which would cost extra energy and natural gas can be used as a fuel without elaborate gas
processing. "In comparison to last year we have been able to increase performance in
methane operation more than fivefold", Dr Robert Steinberger-Wilckens, who has been
head of the fuel cell project at Research Centre Jülich since February 2002, is delighted
with the progress made. "This is above all thanks to the ingenious design and the
very efficient materials development at Jülich."
At the moment, the major barrier to commercialization of the SOFC is
the high cost of materials, components and manufacturing. However, the Jülich scientists
are well equipped to take these hurdles in their stride. They are already working
intensively on new materials in order to further increase the power and longevity of their
cells whilst at the same time lowering costs. Their declared goal is a 20-kilowatt system.
This power range is interesting because it opens up a wide field of possible applications.
"Starting from a 20-kilowatt SOFC system you can operate in all directions, so to
speak. This performance is at the upper limit of what is required to supply a multiple
dwelling estate with electricity and heat, and is at the lower limit of a combined heat
and power station for a residential area", Robert Steinberger-Wilckens explains the
significance of the development and adds: "For 2004 we have set our sights on a
complete 20-kilowatt SOFC system for use in buildings."

The project, bringing together DaimlerChrysler AG, BMW
AG, GM unit Adam Opel AG, and Ford's German research centre, will set up a hydrogen
refuelling centre in Berlin and a fleet of 30 cars to test the new technologies. European
car makers have been investing in green technology to safeguard their long-term survival
against the risk of fossil fuels running out and increasing government pressure to build
cars which damage the environment less. The five-year programme has similarities to one
set up in California two years ago to test fuel cells, which use hydrogen to create
electricity, said Wolfgang Scheunemann, a DaimlerChrysler spokesman.
The drive will end when engineers drive across the
Potomac River into Washington, D.C., from Arlington, Va., after starting in San Francisco
May 20 in a Mercedes-Benz A-Class subcompact car. The final miles will be a ceremonial
finish that signals what appears to be a new commitment by car companies to pollution-free
fuel cells. "A vehicle that is robust enough to actually drive over 3,000 miles
through the dust, dirt and grit of the real world is a major accomplishment," says
Kim Bergland, outreach director of the National Fuel
Cell Research Center at the University of California-Irvine. She predicts that
fuel-cell vehicles will begin appearing in showrooms by 2008. Automakers plan to put them
into government and test fleets within the next two years to rack up valuable experience
before then.
Rasul was quick to sense the need for
political as well as corporate allies. In the late 1980s, smog-choked California led the
nation in imposing tough deadlines on the auto industry. By the early 1990s, some of the
state's demands had begun to seem unrealistic because of slow progress in the development
of electric vehicles. Until Rasul came on the scene, few experts saw fuel cells as an
option. But Rasul had shrewdly named Larry Berg, a former state air-quality regulator, to
Ballard's board. When California's rules were redrafted in 1995, Berg saw to it that fuel
cells figured prominently. "I inserted the language," Berg says. "But I
couldn't have done it without Firoz." Rasul went on to co-found the California Fuel
Cell Partnership, which today includes eight automakers, four oil giants, and six
government agencies. Rarely has a development effort united so many adversaries: At its
facility in Sacramento, Ford, General Motors (GM), Toyota, and others work in side-by-side
bays on 19 test vehicles, 13 of them equipped with Ballard fuel cells. "No one has
done more than Firoz to take the fuel cell from the bench onto the roads," says Alan
Lloyd, chairman of the California Air Resources Board.
Now this island of lava on the edge of the Arctic plans
to become the world's first society to ditch fossil fuels entirely, relying instead on
hydrogen made using the power of its roaring rivers and volcanoes. Enthusiasts even talk
about it one day becoming the "Kuwait of the North" as an exporter of the new,
green fuel to markets in Europe.
Global distributed generation capacity will
increase from 20,000 MW (megawatts) to near 300,000 MW by 2011 according to
Distributed Generation Global Market Analysis, Technology Assessment and
Outlook, a new study by Allied Business Intelligence (ABI). different business and
regulatory landscape and DG stakeholders will need to customize their solutions for
varying market applications in each region.
"In many ways, we've been held hostage
to petroleum for a century," [Larry Burns, GM Directer
of R&D] said. Breaking those shackles with new energy
sources will have huge ramifications not only for automakers but also for economies,
nations and the planet, he said. The technology will spawn competition among oil, gas and
electricity companies to power the so-called hydrogen economy, potentially lowering prices
for consumers, he said. ...Drivers could fuel their vehicles at home at night, paying
off-peak charges for the electricity or gas they convert to hydrogen. Vehicles themselves
could become a power source for homes or businesses. If just one of 25 vehicles currently
in California had a fuel cell, those one million vehicles could generate more juice than
the state's entire utility grid, Burns said.
Berliner Verkehrsbetriebe (BVG), the biggest
German urban transport utility, and the French oil company TotalFinaElf have made an
agreement on joint research on hydrogen on 7. May in Berlin. Starting in autumn BVG will
operate a fuel cell bus in public transportation in Berlin in the framework of a research
project supported by the European Commission. Until 2005 five to ten buses which use this
technology will be running in Berlin. A hydrogen competence center with filling station
and maintenance workshop will be established on one of the bus yards of BVG. The Berlin
model project is related to similar projects, also EU funded, in Lisbon and Copenhagen.
On 26. April 2002 a competence network "Future
Technology Fuel Cell Rhineland Palatinate" was created in Mainz, the capital of the
German state of Rhineland Palatinate. The network will be a forum for the parties active
in the state in this field, and it is a continuation of the former efforts towards
sustainable energy generation with low emissions. The driving force for the initiative was
the ministry for environment. The ministries for science and the ministry for economy and
transport support it. The German Hydrogen Association has been an expert partner for the
environment ministry for a long while. A hydrogen and fuel cell initiative for the state
of Hesse was founded on 30. April 2002 at Frankfurt-Hoechst. The German Hydrogen
Association has a coordination function in the initiative, while the company Infraserv
Hoechst, located in the industrial area of Frankfurt-Hoechst, supports it and the state
ministries for environment and economy accompany it.
The study, released at the Hart World Fuel Conference,
assessed fuel sources, processing techniques and propulsion systems. A total of 36 fuel
pathways and 18 propulsion concepts examined for the 2010 timeframe, from conventional
engines to advanced concepts, were analyzed under European driving conditions. (The study
assessed energy efficiency and greenhouse gas emissions, but not costs.) Experts examined
the complete chain, from the production of fuels from their basic feedstock components to
the actual consumption of the fuel in the car, what scientists call
"well-to-wheel" analysis. Ludwig Bolkow Systemtechnik (LBST), a research
institute in Ottobrunn, Germany (near Munich) acted as a scientific advisor and
consultant. BP, ExxonMobil, Shell and TotalFinaElf energy companies provided additional
data and analysis. A principal finding of the study was that fuel cell vehicles using
hydrogen produced from natural gas could be attractive in terms of well-to-wheel gas
emission depending on the source of the natural gas. However, optimum results are realized
when renewable energies such as biomass or wind power are used to produce the hydrogen.
The activities were part of "Fuel Cells: Driving the
Future," GM's nationwide in-school fuel cell education program, which is expected to
reach nearly 3.5 million middle school students. Developed by Lifetime Learning Systems, a
division of Weekly Reader Corp., the program provides science teachers with an engaging
curriculum that highlights the fundamentals of hydrogen fuel cell technology. "Within
their lifetimes, fuel cell technology will be part of these students' daily lives,"
said Elizabeth A. Lowery, GM vice president of environment and energy. "By creating a
curriculum that explores the technology now, we hope revolutionary ideas and research will
make that day come a little sooner."
The report concludes that the car of the
future will be powered by a hydrogen fuel cell, producing no emissions other than water,
and that such motors will start to outnumber "conventional" engines from about
2030. "A small number of internal combustion engines may remain in production as late
as 2050 to power `enthusiast' cars for pure driving enjoyment," it says. "While
the change over to fuel cells is taking place, the hybrid internal combustion/electric car
will be built in considerable numbers to fulfil a transitional role."
The much-anticipated launch date of a portable generator
powered by a Ballard fuel cell is "going to be soon," said Firoz Rasul, chief
executive of Ballard Power Systems Inc. Originally scheduled for launch at the start of
the year, Coleman Powermate's portable generator -- described as the world's first
fuel-cell based consumer product -- has attracted a lot of attention from industry
observers keen to measure the public's acceptance of the technology. At Ballard's annual
meeting yesterday, Mr. Rasul said the foray into home generator market is one of a number
of efforts undertaken by the company to broaden its market and hasten the date when it
will become profitable. However, he declined to give a date when the company will turn the
corner.
The new chairman of the Japan Automobile
Manufacturers Association said Thursday he will work to promote fuel cells and other
technologies less harmful to the environment than the combustion engine. Yoshihide
Munekuni, also chairman of Honda Motor Co., called on the government to provide
infrastructure and promote deregulation necessary for green vehicles to become a success.
Scientists from the Scottish Fuel Cell Consortium(SFCC)
told island entrepreneurs of the vast potential that exists to use hydrogen to power
everything in the home and in the workplace. There was even talk of the potential to
manufacture cars, powered by low cost hydrogen-based fuel cells, on the island. Professor
Sinclair Gair, a leading member of the consortium, said that, if financial backing was
forthcoming, they could be producing hydrogen on the island in a year. And within 18
months they could be packing that hydrogen into power cells, ready for use. ...If the
island becomes home to the project a second wave power station will be built and water
would be electrolysed, to produce hydrogen, which would then be put into fuel cells.
...BMW has already expressed an interest in the consortium's work, as has the industrial
arm of Rolls Royce.
Scientists want to turn Islay into the world's first
hydrogen-powered island. They plan to make the clean fuel by treating water with
electricity generated from a wave power station already operating on the island. ...The
plan is the brainchild of the Scottish Fuel Cell Consortium, a grouping of scientists and
businesses backed by Scottish Enterprise. ...Islay was picked because of its
ground-breaking Limpet power wave power station in the village of Portnahaven. Built by
the Inverness company Wavegen, the Limpet is the first wave-driven power station to feed
renewable energy directly into the national grid. The Islay project is a UK leader at a
time when governments and industry across the world, faced with diminishing fossil fuel
resources, instability of oil supply, and rampant global warming, are engaged in a dash to
master hydrogen fuel cell technology.
When Wolfgang Reitzle, the head of Ford's
luxury car division, known for his glamorous lifestyle, fast cars and marriage to gossip
queen Nina Ruge, was appointed Linde's new CEO-to-be in late April, the company's dusty
image became the talk of the business community. ...He has recently hinted at expanding
Linde's fledgling fuel systems business into a "new business leg". In contrast,
Linde's outgoing management used to play down the group's immediate earnings potential in
hydrogen fuels. Although their application in cars is still at an early phase,
emission-free fuels are widely considered the answer to global warming. Linde already
co-operates on developing zero-emission hydrogen fuel cells with BMW, where Mr Reitzle
headed its production before being ousted in a management reshuffle in 1999.
The research arm of Honda Motor Co. and a
Latham, N.Y., firm that produces electric generators announced Tuesday that they will work
together to tackle one of the peskiest obstacles to mass production of fuel-cell vehicles.
Honda R&D Co. and Plug Power Inc. said they will collaborate on research into
home-based hydrogen vehicle refueling stations. The refueling stations they will work on
will provide heat, hot water and electricity to a home while also producing hydrogen for a
fuel-cell vehicle. The stations will be fueled with natural gas. Home refueling units
could help speed public acceptance of fuel-cell vehicles, further building a case for
automakers to build them, said Mark Sperry, Plug Power vice president.
The company is doing research on the
improvement of structural membranes. Usually, a porous membrane carrying particles of a
proton conductor of the fullerene system is used. But Sony is considering the use of a
structural substance produced by the materials of fullerene system only, namely, a polymer
of a proton conductor of the fullerene system.
The United States continues to import more than 50
percent of its petroleum from other countries. That remains a concern for some. "Our
over-reliance on foreign oil has become a national security issue," said U.S. Rep.
Chet Edwards, D-Waco. The Bush administration has made drilling for oil in Alaska's Arctic
National Wildlife Refuge a top priority, recognizing that the importation of some 10
million barrels of foreign oil each day cannot continue, according to a federal Department
of Energy news release. The release announced a partnership between that agency and the
nation's biggest three auto makers to develop an automobile fueled by hydrogen.
Ohio must become a national leader in developing fuel
cell technology or risk losing auto-related jobs that are a cornerstone of the
states manufacturing economy, Gov. Bob Taft said Thursday. Taft struck an urgent
note as he unveiled his three-year, $100 million fuel cell initiative in this Cleveland
suburb at Graftech Inc., which provides graphite plates used in fuel cells.
The second of three fuels it plans to use
for fuel cell demonstrations, the California Fuel Cell Partnership (CaFCP) recently opened
a new methanol fueling station at its fuel cell vehicle demonstration center in West
Sacramento. Many technological advances are incorporated into the CaFCP methanol fueling
station. These include anti-siphoning devices and a user-friendly, fixed lock system
between the fuel nozzle and the vehicle that improves safety and lowers spill potential.
The station was designed and built by the Methanol Fuel Cell Alliance, which is an
industry group that includes several CaFCP members such as Methanex, DaimlerChrysler, BP and Ballard Power
Systems.
The truck demonstrated near GM's fuel-cell
research facility is equipped with a processor that reforms low-sulfur gasoline though a
series of chemical reactions. The fuel is mixed with air and water and passed over a
series of catalysts that separate hydrogen from carbon. The hydrogen is sent to the
fuel-cell stack, where it is combined with oxygen from the air to produce electricity.
...Pure hydrogen-fed fuel cells produce no harmful emissions, while those using gasoline
or other fuels are not pollution-free.
How does open source car design work?
The honest answer is that we won't know until we have done
it. But we have plenty of ideas, which will develop over the coming months
as we share the designs for the Riversimple technology demonstrator and
start to produce collaboratively a production prototype.
There are lots of inspiring examples from open source
software, and we are being advised by people with experience in this area.
But there are many differences between open source hardware and software
design.
Differences between open source hardware and software
There are some major differences between open source software
and hardware design:
- There is a "gap" between the on-line design work and the finished
product delivered to the consumer. Not only is there substantial physical
testing to be done, but also there is significant work to be done to turn
the designs into an actual functioning product (we like the analogy of a
food recipe – a recipe is not a meal, you need a chef to turn it into a
meal). The answer we believe lies in establishing the right relationship
between 40 Fires and the manufacturers (the first of which is Riversimple),
where each party has its needs met.
- There’s a technical challenge to share ideas on-line, where there is
no satisfactory open source CAD (Computer-Aided Design) application. Our
solution is to use a low tech approach at first, using a wiki-based
website and freely available 3-D viewers to show the 3-D drawings. In time
we may get involved in developing a OS CAD program.
- Licensing. We cannot simply take the standard OS software license
(the GPL is the most common), since we are dealing with hardware, which is
not so well protected by copyright. See further down for some thoughts on
the licensing issues.
We'd like to hear from you!
As in Open Source software projects, we are not attempting to
do everything at once and we don’t have to. The designs that Riversimple
is licensing to 40 Fires resemble in many ways the code base which a
complex software project starts with.
However, because a car is different to software and requires
different development stages and processes, we will be asking for input
into specific areas, as well as procedural matters.
That's why we would like to hear from you, not only from
engineers or designers, but also if you have contributed to large scale
open source software projects and can help set up our project management
structure. Lawyers with an understanding of copyright and patents would
also be useful as we review the most appropriate license to use and if and
how we should be using patents for some new inventions which emerge.
To get involved, send an e-mail to
participate@40fires.org explaining your interest and skills.
The stages
We envisage different stages:
Stage 1 Over the coming months, starting this month (July
2009), we will make available design schematics from the Riversimple
technology demonstrator vehicle, together with a description of each
component's function in the whole system, and a vehicle design brief for
the production prototype. We will provide a mailing list or discussion
forum to enable comments and discussions. At this stage we expect
Riversimple, as the creator of the original designs, to be leading the
discussions.
Stage 2 As the detailed discussions develop, we expect a
broad consensus to emerge amongst the participants as to which is the best
solution to pursue for each design . By this stage, we expect the
conversations to be more democratic, with a broad cross-section of
collaborators participate, sharing their knowledge and insights.
Stage 3 We start creating detailed designs collaboratively
and publishing them on-line. Eventually an entire vehicle will be created,
and tested, on-line. We are aiming to complete the design of the
production prototype by the summer of 2010.
Stage 4 Riversimple and other entrepreneurs, under license
from 40 Fires, can start downloading the schematics and building and
testing the vehicles. With the lessons from this, work can start on an
improved production prototype.
Are our designs free (as in beer)?
Richard Stallman famously said that free software is "free as
in speech not free as in beer."
Are our designs free?
We consider that the designs themselves will be free in the
sense of free speech, with one exception. Currently we have chosen a
Creative Commons, non-commercial license. So the designs can be used,
modified, distributed under the same license terms but not for commercial
purposes.
We have chosen to be conservative at this stage and not
allowed commercial use. This may change - we intend to set up a discussion
group to debate this. The issue is that we don't want a large,
profit-focused organisation taking the designs and starting manufacturing
with them yet. We intend that when we grant a manufacturing license, this
will be for a small fee (say $10 per car) to cover 40 Fires running costs.
We are also keen on collaborating so if a commercial
organisation wants to use the designs, we'd like to chat with them first
before allowing them to use the designs for commercial purposes.
The licensing issues are very complex (patent law is not
copyright law; cars are not software) and we don't pretend to have all the
answers. It is quite possible that our license may in the end not meet the
strict requirements of the Free Software Foundation. But all we really
care about is that the license works to ensure that the cars can be built
in hundreds of different variations around the world, by local companies
and entrepreneurs as well as big multinationals if they like, and that no
one company (whether Ford or Riversimple) can dominate the market and keep
the ideas to itself.
