Fuel Cells Will Be Viable As Adoption Curve Emerges

 

Dec 12 - Power Engineering

The following report could have been ripped from a newspaper 30 years ago:

The technology may one day transform the industry, but so far hype has outpaced reality. Costs must decrease and product life increase to achieve market adoption on a mass scale. Early adopters are few and far between. Research is mounting in different directions.

Such a report would have accurately assessed the state of the microelectronics industry at the time. It also sounds like a current assessment of fuel cells. In other words, such a 30-year-old news clip bodes well for the future of fuel cells, because from the hype and uncertainty of the 1970s emerged an adoption curve that made mass marketing of microelectronics practical while advancing innovation. That same type of curve is now emerging for fuel cells - and with the presence of certain drivers, it can point the way to a more stable blend of grid and distributed generation in the years ahead.

The Home. Energy Station is a joint effort with Honda and Plug Power that provides heat and hot water for the home and hydrogen for the fuel cell car.

Many new industries begin with grand projections, and fuel cells are no exception. Even six or seven years ago, "a fuel cell in every home" seemed, to some proponents, achievable in a few short years.

That overarching dream has been replaced by a wide assortment of research paths - many pursued by global industry leaders, and many likely to contribute to a solid foundation for future commercialization. To cite a few examples: Plug Power and Vaillant, a $2.5 billion manufacturer of wall-hung boilers for Europe, have begun developing fuel cells that provide combined heat and power (CHP) to commercial and residential customers. Major automakers are actively researching the viability of fuel cell vehicles. Honda and Plug Power are working on home refueling systems for these vehicles- systems that also provide heat and electricity to the home.

Supporting such efforts is the U.S. Government, which has stimulated innovation through research funding, tax credits and other initiatives. Most visibly, President Bush has instituted a $1.2 billion hydrogen fuel cell initiative to reverse the U.S. dependence on foreign oil. Washington has also announced its FreedomCAR program, a partnership with automakers and others to fund key research in automotive fuel cell technology.

All these resources have contributed to the progress of fuel cells. And all will be necessary to overcome, among other things, the daunting challenge posed by a vicious cycle of cost and market viability. To make fuel cells commercially viable, manufacturers must lower unit costs. One path to lower unit costs is higher manufacturing volume, which creates economies of production. Higher volume, in turn, can only occur with demand from a critical mass of customers.

Yet only a few customers can invest in fuel cells because of high unit costs. Microelectronics faced the same dynamic. Large mainframe computers worked well for large enterprises but hardly fit the consumer market. Yet we saw the industry transform the vicious cycle into one of dizzying innovation, lower costs, smaller size and massive market acceptance. How can fuel cells follow suit?

EARLY ADOPTERS

In the last few years, a viable curve has begun to take shape. Early adopters of fuel cell technology have already emerged in a variety of applications. Portable fuel cells for mobile electronics are finding their way into military and industrial applications. A number of companies, including giants like Motorola and Samsung, are working to develop the technology. On the stationary front, the Long Island Power Authority has invested heavily in fuel cells to supplement its grid during peak load times, while also installing them on a limited basis in residential and small commercial sites.

BACKUP POWER

An urgent need in several industries has brought the next point on the curve into view. Burgeoning consumer demand for new telecom products, such as DSL and wireless broadband, is placing ever- higher demands on networks, while reliability and quality requirements remain deep into the nines. These trends have telecom network planners scrambling to upgrade and optimize plant infrastructure - including backup power - amid severe competitive cost constraints.

In this backup power market, fuel cells are beginning to find a niche. Their light weight, quiet operation, zero emissions (when operating on hydrogen) and peak performance in a broad temperature range have made them an excellent fit for backup power applications in the outside plant, where traditional backup power solutions have fallen short. Already the case can be made for fuel cells being economical - in price, life-cycle cost or both - compared with other options in this market, such as lithium-ion batteries.

These advantages in backup power will find ready application in other industries too, most notably broadband and uninterruptible power supply. Also around this stage, certain mobile vehicles - rider trucks, for example, and forklifts - will find that the predictable runtime, high state of charge and affordable cost of fuel cells are valuable qualities.

STATIONARY FUEL CELLS

Only as these markets mature - as performance feedback from the field informs further innovation, which in turn drives costs and prices down - will stationary applications begin to take hold on a wider basis. As with backup power, the first uses will come in the areas of greatest need: remote residential customers and others who are off-grid. By this point in the adoption curve, fuel cells can replace incumbent technologies that have proven either too unreliable or too expensive for consistent operation. This application will enable fuel cell manufacturers to begin field- testing other uses of fuel cells: for CHP, perhaps, or as a hydrogen home refueling station.

From remote areas, the adoption curve takes us inward. Further innovations and accompanying price reductions will make stationary fuel cells a power option for commercial, industrial and eventually residential customers. Even with home users, however, fuel cells will almost undoubtedly serve to complement the grid.

AUTOMOTIVE APPLICATIONS

Alongside the emergence of stationary applications, we should see the first generation of automotive fuel cells begin to achieve market acceptance. Hand in hand with this will be the increasing use of residential fuel cells as home relueling stations, providing heat and power to the home while generating hydrogen fuel for the family vehicle. Such refueling stations may help to explain why transportation applications, which receive so much current attention, might be so late to market - not because of the pace of current research, but because we currently lack the hydrogen infrastructure to make fuel cell vehicles practical on a wide scale.

Refueling stations, of course, mean on-site hydrogen generation - an application that is already in development. Plug Power, for instance, has just begun to market an on-site fuel cell that generates hydrogen for industrial uses.

It would be lovely to think that fuel cells will evolve effortlessly, driven by a positive cycle of innovation, lower unit cost, higher sales and more funding for more innovation. In reality, fuel cell development will require certain drivers, especially at sensitive points on the curve, and transitions between stages. Several players on the energy stage are well positioned to provide those drivers.

OF GOVERNMENT AND INDUSTRY

Federal and state governments are significant players. Already an early adopter, Washington could further mitigate the vicious cycle by powering more of its operations through fuel cells. The Renewable Portfolio Standards enacted in some states include fuel cells as a renewable resource, providing yet another early-adopter market.

On another critical front, government could work to remove competitive barriers, especially in interconnection standards. Lengthy application processes and high fees have made it cost- prohibitive for fuel cells to operate in many areas. To optimize fairness in the energy market, several states have developed interconnection standards that protect utilities while facilitating the use of fuel cells. The creation of a national standard - perhaps along the lines of IEEE 1547 -could promote cross-border commerce for iuel cells and instill confidence that the grid is being preserved.

Many drivers can also come from within the fuel cell industry. The active presence of Fortune 100 companies in research provides a powerful force for moving fuel cells toward commercialization. Now the challenge is to coordinate their efforts, and those of others, in a way that accelerates development.

A roadmap generated by a respected source would serve the same function, and provide the same benefits, as a corporate strategic plan. Fortunately, such sources exist. Established industry organizations, like the U.S. Fuel Cell Council, command sufficient respect to initiate a wide-ranging roadmap that would draw the attention of most involved with fuel cells. Such a roadmap could recommend a timeline and action steps for completing various applications. With this in hand, industry players could direct their research and production energies to the applications with highest near-term potential, with the thought that such e\arly success would drive the industry on to longer-term accomplishments.

Another self-help strategy for fuel cells takes yet another page from the microelectronics handbook. By forming consortia like International Sematech to conduct pre-competitive research, the semiconductor industry has driven innovation while allowing the consortia members to direct resources toward more bottom-line concerns. The same could easily happen with fuel cells, especially given the number of companies in the field and the collective research capability they represent.

If fuel cells can play a significant role in industrialized nations as a supplement to the grid, how much more can they contribute in developing countries where no grid is available-now or in the foreseeable future. The industry can begin preparing now for what will eventually grow into a global market: creating international organizations to enhance cooperation, engaging in international advocacy, working to help other nations develop viable standards, helping open markets to drive industry growth and competition.

The first steps toward the global market have just recently been taken. Last year, the world's leading fuel cell organizations signed an agenda that will initiate collaboration on a variety offrants. Among other activities, the organizations agreed to stage a second Fuel Cell Summit of Vehicle Demonstration Programs, share information over the Internet, exchange information on test protocols and explore other avenues of cooperation.

THE VALUE OF PATIENCE

As we have seen, fuel cell companies need not play this out in a vacuum. Instead, they can look to their counterparts in microelectronics for a template. Microelectronics has, for instance, had to develop standards to drive volume and ensure market readiness. It has lobbied before government for research funding and purchase programs. It has expanded into a global market on a tumultuous scale.

It has also taught the value of patience. Even in an industry that most equate with speed, personal computers took 15 years just to reach 25% commercialization - and even that is an exceptionally last adoption rate by the standards of many inventions. The lesson here is for fuel cell enthusiasts to maintain focus without expecting too much too fast.

Will these lessons from microelectronics play a role in the unfolding adoption curve for fuel cells? It depends on the extent to which the industry pays attention to them. If fuel cell manufacturers, research concerns and other supporters apply the microelectronics paradigm, the future of fuel cells - and the future of power generation - may fare well for many years to come.

EARLY ADOPTERS OF FUEL CELL TECHNOLOGY HAVE ALREADY EMERGED IN A VARIETY OF APPLICATIONS.
