Mr. Chairman and Members of the Committee. Thank you for the opportunity to be here today to testify on behalf of General Motors. I am Byron McCormick, Executive Director of GM's Global Fuel Cell Activities, and I head the team that is developing our hydrogen-powered fuel cell vehicles.

The Promise of Hydrogen Fuel Cells

Fuel cells and hydrogen are core to GM's advanced propulsion strategy. We are committed to improving the fuel economy and emissions performance of our vehicles by executing a comprehensive three-phase technology plan that includes advanced internal combustion engines and new transmissions in the near term, followed by hybrid vehicles … but our ultimate vision is to establish leadership in hydrogen fuel cells.

Today, I would like to tell you why General Motors believes hydrogen fuel cell vehicles are so important.

· Fuel cell vehicles running on hydrogen fuel are the ultimate environmentally friendly vehicles because their only emission is water. The fuel cell supplies electricity to an electric motor that powers the wheels. The fuel cell produces electricity by stripping electrons from hydrogen that travels through a membrane to combine with oxygen to form water.

· Fuel cell vehicles are on the order of twice as energy efficient as the internal combustion engine, have no pollutant emissions, and are quiet.

· Fuel cell vehicles enable energy feedstock diversity, which will increase energy independence and introduce competition into energy pricing - potentially bringing down fuel and energy costs in the long term and making prices more stable.

· Hydrogen fuel cells can substantially reduce greenhouse gas emissions. When we look at fuel cell vehicles on a "well-to-wheel" basis, they demonstrate outstanding potential to reduce or eliminate well-to-wheel greenhouse gas emissions and improve overall energy efficiency, even taking into consideration how we make hydrogen today. In the future, we can do even better, producing hydrogen using methods that are renewable and have no adverse environmental impact.

· Fuel cells also enable innovative vehicle designs that show promise of being more compelling, affordable, and sustainable than today's vehicles. Today, there are over six billion people in the world. By the end of this century, that number will approach 10 billion. Most of these people will reside in emerging economies where the demand for personal transportation is expected to escalate rapidly. Since only 12 percent of the world's population currently own automobiles, if we are to fulfill the aspirations of the remaining 88 percent for the personal freedom that the automobile provides, we must find the means to make our vehicles sustainable, more functional, and more affordable.

· Finally, fuel cells are a potential source not only of transportation power, but also of electrical power. The development of this technology will create new, more environmentally compatible distributed electric power-generation possibilities. The automobile could provide electrical power to homes and worksites. Power on today's electrical grid could be supplemented by the generating capacity of cars in every driveway. For example, if only one out of every 25 cars in California today was a fuel cell vehicle, their generating capacity would exceed that of the utility grid. A typical midsize fuel cell vehicle would produce 50 to 75 kilowatts of electrical power, where a typical household may use 7 to 10 kilowatts at peak load.

General Motors' Fuel Cell Development Program

Recognizing the potential of fuel cell technology, approximately six years ago General Motor consolidated and accelerated its fuel cell activities. The GM fuel cell team was given an important directive by management: Take the automobile out of the environmental debate. Regardless of whether the environmental debate is focused on air quality, climate, or overall sustainability, GM leadership recognized that global conditions must inspire bold, thoughtful actions. Our commitment to fuel cells is clear in the significance of our investment - we have spent more than a billion dollars to date, and growing.

This investment in our fuel cell program has yielded outstanding results:

· In the last four years, we have decreased the size and weight of our fuel cell stack for a given power by a factor of ten.

· With each new generation of technology, we have also reduced the cost and complexity of our stack.

· We also are now able to start fuel cells from freezing - minus-40° Celsius (minus-40° Fahrenheit) - in substantially less than a minute.

· We have developed a series of hydrogen fuel cell vehicles, which demonstrate how fuel cell propulsion can be optimized for the existing automobile. Our HydroGen1 prototype holds 15 fuel cell vehicle performance records and has been demonstrated around the world. HydroGen3 is our first fuel cell vehicle able to dispense with a buffer battery, needed in previous generations to meet performance peaks. With an improved electric drive and optimized fuel cell system architecture, HydroGen3 has outstanding acceleration and is capable of easily cruising at 100 miles per hour.

· We also have created the AUTOnomy fuel cell concept and a drivable prototype called Hy-wire. These vehicles combine fuel cells with by-wire electronics and other advanced technologies in a revolutionary design that "reinvents" the automobile. These designs could make vehicles both more affordable and more compelling for our customers because they enable substantially enhanced functionality with fewer vehicle components, a longer-life chassis, and a smaller number of vehicle architectures - all of which have the potential to reduce manufacturing costs.

· We also are testing our fuel cell vehicles in the real world. Over the next few years, we will be fielding several small demonstration fleets. GM and Shell Oil recently began a joint demonstration program here in Washington, D.C. to test fuel cell vehicles and hydrogen fueling technology. The two-year program, which began earlier this month, will give government officials - like you and your staffs - the chance to experience firsthand what driving a fuel cell vehicle is like. Next month, in partnership with FedEx, we will begin our first commercial trial of a fuel cell vehicle. This program, which will take place in Japan, will run for one year. Our HydroGen3 vehicle is being used in both demonstration programs.

These milestones represent remarkable progress. In fact, we believe our rate of progress will allow us to market stationary fuel cell units by mid-decade and to introduce hydrogen fuel cell vehicles by 2010. But even as we are encouraged by our progress to date, it is crucial to recognize that the race for fuel cell development is a marathon, not a sprint. No one should overlook that major economic and technical obstacles must be conquered before these vehicles can be brought to market and can become commercially successful.

Fuel Cell Commercialization Challenges

Hydrogen storage, cost, and fuel infrastructure are the major barriers to commercialization.

Hydrogen Storage: With respect to the vehicle, hydrogen storage is the toughest hurdle. GM has demonstrated both cryogenic liquid and compressed hydrogen storage tanks in our prototype vehicles. While these methods will suffice for early market introduction, over the long term, we should seek "solid" storage techniques such as chemical or metal hydrides, which will more efficiently and cost-effectively store significant amounts of hydrogen on board the vehicle.

Cost: The key economic challenge over the coming years is to reduce cost. Our goal is to attain a cost target of $50 per kilowatt for our fuel cell propulsion system (from stored hydrogen to torque at the wheels) by 2010. This equates to the cost of a conventional internal combustion engine. To this end, we have achieved a cost improvement with each new generation of fuel cell stack technology, and we have a good understanding of the additional progress we must make in reducing the cost of each subsystem to achieve total system affordability.

As we reduce cost to get to automobile-scale applications, many attractive business applications for stationary fuel cells are developing. In fact, we see distributed generation as a key steppingstone to the introduction of fuel cell vehicles. Working with our strategic partners, we have developed several fuel cell power generators using the same fuel cell stack technology as we are developing for our fuel cell vehicles. Earlier this month, here in Washington, we announced an agreement by Dow Chemical to purchase 35 megawatts of fuel cell power from GM. This is the largest contract to date in the fuel cell industry. Under the seven-year agreement, 500 GM fuel cell units will convert co-product hydrogen from Dow's chemical manufacturing processes into electricity and heat for its facility in Freeport, Texas. Dow is also considering using fuel cell power at several of its other plants worldwide.

We also recently announced that we will conduct a demonstration of a 75-kilowatt direct-hydrogen unit in both the U.S. and Japan. We expect to be able to market these units in the 2005 timeframe. Early units are intended to provide backup electricity for uninterruptible power supply systems, such as hospitals and high-reliability data communications networks, and to handle peak power demands. Real-time power markets and common interconnection standards for small-scale fuel cell power units could be a key enabler to the early roll out of stationary applications of our fuel cell technology and, by extension, the early rollout of fuel cell vehicles. It should be emphasized that every hydrogen-fuel cell distributed electric generator is a potential vehicle filling station, since the hydrogen is by definition available at that location - which means that distributed electric generation is a critical steppingstone to the hydrogen refueling infrastructure.

Fueling Infrastructure: The third challenge we have to overcome is developing business models for the deployment of a hydrogen infrastructure and piloting technologies to support it.

One of the more exciting aspects of hydrogen is that there are many scenarios for producing and delivering it. Hydrogen could be generated at local filling stations from gasoline or natural gas, using an appliance-like devise called a "reformer." Hydrogen also offers the potential for refueling at home using an electrolyzer or natural gas reformer. This takes advantage of the fact that water, electricity, and natural gas are already available in our homes and businesses.

Initially, hydrogen will likely be produced from many sources. Steam reforming of natural gas will probably be the first source because industry already uses this technique to produce large amounts of hydrogen - nine million tons per year. This process does produce carbon dioxide - about half as much as gasoline on a well-to-wheel basis. The cost of natural gas would presumably go up due to limited supply. However, it is doubtful that hydrogen demand will increase so rapidly as to adversely affect the supply of natural gas. There should be sufficient supplies to produce hydrogen for the early years of fuel cell introduction. We estimate that if we had one million fuel cell cars on the road and all of the hydrogen for those cars came from reformed natural gas, it would increase the current demand for hydrogen by 0.2 percent. If you had ten million fuel cell vehicles, it would increase current demand by 2 percent.

Petroleum companies have said that hydrogen can be generated from natural gas today at approximately the same cost as conventional fuel. A key issue will be implementation of an efficient new hydrogen distribution system. Implementation would include "on site" creation of hydrogen from various feedstocks via electrolysis and reformer technologies. Again, a key ingredient will be nationally uniform codes and standards to ensure rapid implementation.

Call to Action

GM has always believed that it will take a three-way partnership involving the auto industry, energy companies, and government to successfully commercialize hydrogen fuel cells for vehicles and stationary applications. There are a number of areas where government could have an immediate impact:

We would welcome a major new national R&D initiative on hydrogen storage and production that would leverage the creative capabilities of our government labs, universities, and industrial research facilities.

We would also like to see a similar aggressive R&D program focused on breakthrough fuel cell materials.

We believe the Department of Transportation should "undeclare" hydrogen as a hazardous material and treat it as a fuel.

And since federal and state agencies will have a role in the transition to the hydrogen economy and they should begin that process today by evaluating the use and impact of hydrogen and fuel cell technologies in their operations.

Finally, the government should take the lead on development of a national template for the codes and standards that will be required for hydrogen, fuel cells, and distributed electric generation.

Summary

To summarize GM's position on the emerging hydrogen economy:

1. We see fuel cells as the long-term power source. GM's global fuel cell program seeks to create affordable, full-performance, exciting fuel cell vehicles that meet or exceed customer expectations and emit only water vapor from their tailpipes. We believe that customers will want to buy these vehicles.

2. We see hydrogen as the long-term fuel.

3. With continued progress on technology, we think fuel cell vehicles could be cost competitive by the beginning of the next decade.

4. We think stationary fuel cells will pave the way for fuel cell vehicles. By taking our vehicle fuel cell technology to the stationary power market, we are learning how to improve fuel cell reliability and durability, move further down the cost curve, build the required manufacturing and supply base, and accelerate infrastructure development.

5. When we think of hydrogen infrastructure, we think of appliances not just pipelines. Traditional infrastructure such as pipelines and centralized plants is not the only means to provide hydrogen for fuel cell vehicles, although it will be part of the solution. If hydrogen is made from natural gas at fueling stations or homes, it will not be necessary to transport hydrogen. We will need cost-effective and efficient reformer appliances. Similarly, if hydrogen is made via electrolysis, we will need practical and affordable electrolyzer appliances. This is an area ripe for entrepreneurial exploration and rapid implementation. For this reason, we are stressing the need for governmental action on nationally uniform standards for distributed electric generation, hydrogen storage, and safety codes.

6. We are focusing on small demonstration projects for the next 3-5 years, to gain engineering knowledge that we will apply to technology development still needed for the vehicle and to increase our cycles of learning with respect to infrastructure requirements and the codes and standards that need to be addressed to enable the use of hydrogen as our future automotive fuel. I would just caution that demonstration projects are costly and require many of the same resources we are using to refine fuel cell technology, particularly on the vehicle side. In the next couple of years, the goal should be to have a limited number of small-scale - but integrated - demonstration projects and then expand those projects later in this decade.

7. In the 5-10 year timeframe, we see industry cooperating with government on larger-scale, real commercial projects that leave a legacy of infrastructure.

In closing, I believe hydrogen and fuel cell-based transportation are the future. The pace of technical progress is accelerating. The U.S. cannot be left behind or sitting on the sidelines. It is clear that we are in an intense global competition for leadership in this race to establish and commercialize fuel cell technologies. In Japan, the kyogikai (which are companies operating under government auspices) are developing a program for the implementation of fuel cell technology. Now is the time for the U.S. government, U.S. industry, and U.S. universities to create a partnership that can lead the world in the charge to achieve this vision.

General Motors and our partners are driving to bring first-generation fuel cell technology to market as rapidly as possible.

Thank you.

I look forward to responding to your questions.
