The station will likely look similar to this self unit. It will cost about $3M USD and fuel 10 to 15 vehicles daily with hydrogen produced by hydrolysis. The energy to split the hydrogen from the oxygen will come from attached solar panels.  (Source: The Center for Energy Research)

Just as the future looks increasingly dim for hydrogen, the industry gets a boost

Prospects of seeing hydrogen vehicles available commercially anytime soon have looked increasingly bleak.  U.S. President Barack Obama has refused to provide significant federal funding to hydrogen vehicle development, supporting battery electric vehicles instead.  In addition, recent research reports indicate that hydrogen would actually release more net greenhouse gas emissions than traditional gasoline, when analyzed over the entire life cycle.

However, there's a ray of light for the hydrogen industry amid the darkness.  Connecticut-based SunHydro has announced plans to transform Interstate 95 into a hydrogen highway.  Those who live in the U.S. East Coast know that I-95 stretches from Maine to Florida and is one of the nation's busiest interstate highways. 

SunHydro will construct 11 stations on the highway.  Each station will be a self-contained hydrolysis unit with solar power collectors attached.  The solar power will provide energy to create hydrogen from water via hydrolysis.  The hydrogen production system will come from an Proton Energy, an alternative energy start-up.  The net process is expected to be much more carbon friendly than transporting hydrogen by truck to fueling stations.

The plan is ambitious.  Explains company president Michael Grey, "Our goal is to make it possible for hydrogen car to drive from Maine to Miami strictly on sun and water.  Having talked to several of the auto manufacturers, the indication that we’ve received is that there has to be a network of stations on the east coast for them to bring the cars here.  They want to bring the cars here, but there’s nowhere to fuel them."

Currently, the hydrogen industry is stuck in a chicken and egg dilemma of sorts.  Lack of vehicles makes stations a poor business investment, while lack of stations make developing hydrogen vehicles problematic.  Paul Williamson of the University of Montana College of Technology, notes,"There’s no sense having hydrogen cars if there’s no place to refuel them. Most of the development is happening in California. Why? Because they have refueling stations."

The initial SunHydro station aim for a gradual build up, initially producing enough fuel to fill up 10 to 15 vehicles a day.  The stations will be located in Portland, Maine; Braintree, Massachusetts; Wallingford, Connecticut; South Hackensack, New Jersey; Claymont, Delaware; Richmond, Virginia; Charlotte, North Carolina; Atlanta and Savannah, Georgia; and Orlando and Miami, Florida.

The stations may cost up to $3M USD a piece in private investment.  Mr. Grey says his company is taking a bold risk shouldering these high costs in order to bolster the market.  He states, "We’ve just decided that somebody needed to start this process. You have a lot of the big companies talk about it, but nobody’s stepped up to the plate and made it happen. You’ve got to have some visionary risk taking if you want to be a company of the future. Otherwise, you’ll fall by the wayside."

Currently, several companies still have hydrogen plans despite the cold reception by the research community and government.  GM has worked for several years on fuel cell-powered Equinox SUVs.  Honda has its FCX fuel cell test vehicle that has seen limited U.S. deployment.  And Mercedes-Benz plans to release F-Cell, a limited edition fuel cell vehicle to “selected customers” in Europe and the United States this spring.  Mazda and Volkswagen are also eying hydrogen plans.

there are significant issues though with this idea.

Lets role down the chart.

Large scale solar installations would be happy to produce electricity at 20 cents per kWh. Germanys Whole-Sale rate for Solar is above 50 cents per kWh... To believe that the solar power for the water spliting occurs at a cost less than 25 cents per kWh is... well extremely optomistic.

Small scale water spliting is at most 50% efficient.

A kilogram of Hydrogen has approx 40 kWh of energy. Meaning to split water into 1 kilogram of hydrogen takes a minimum of 80 kWh of electricity. Since it then needs to be compressed and pumped, probably more like 85 kWh is required to deliever a single kilogram of hydrogen fuel to the end user.

One can travel ~60 miles on 1 kg of Hydrogen in the FCX Clarity. Or roughly a hit of 1.4 kWh -per- mile (.71 miles per kWh collected from panel). That works out fairly significant costs even when electricity is sourced from the grid. When it based on a solar installation as such, its gets dramatically worse.

In comparison, a similar installation using a Sodium Battery or similar would acchieve closer to ~2.75-3 miles per kWh collected from panel (Tesla Roadster 28 kWh/100 miles measured from the wall).

I think Hydrogen is a dead end. Too many things need to happen. Fuel Cell Stacks must somehow become affordable (they are in 100s range right now). Fuel Cell stacks must become more efficient. Electric components must become affordable for use in cars. Hydrogen generation must become efficient and renewable (Even reformulation NG doesn't make sense... why not just use the NG?!?). Hydrogen mobile and physical storage must become more affordable and safer. A completely new infrastructure must be constructed...

I rather have more of the Volt type transition. Gas --> Hybrid --> Mild PHEV --> Strong PHEV --> Full Electric

Reuse of technology implemented in other facets of life. Restoration and Expansion of infrastructure rather than whole new systems.

Also the stations can hardly be off-grid, they would need like 1000 solar panels then for the 15 cars a day. Of course it's a dead end.

However I don't really see the shift to full EVs unless "mobile charging stations" can go to you and quick charge your car if you run out of charge. "Strong" PHEV with synthetic fuels (or biogas) would probably be more realistic for those who wishes to phase out the oil. It might be odd only having to pump up for road-trips though. But everyone won't make the change at the same time. Any way it's along time away from now and the society will look totally different. It's however time for "mild" PHEV now. So maybe in ten years it's the standard for new cars.

1 Kg of hydrogen produces about 16 Kwh out of a fuel cell. 1 kg of hydrogen is equivalent to about 1 gallon of gas. The energy required to produce and compress that 1kg of hydrogen from small scale electrolysis fuel stations is more in the range of 70-75 Kwh. At $0.10 to $0.12 per kwh for electricity off the grid that is some damn expensive gasoline, even with a car that's getting an equivalent of 60 miles to the gallon.

And there are no large efficiency improvements in the system to be had. You might improve the fuel cell another 10-20%, and the electrolysis another 10-20% but that's about it.

As keeir states, hydrogen just makes a horrible inefficient energy storage medium. Even the fuel cell companies like Ballard Power systems can see the economic realities and have abandoned their automotive fuel cell programs.

Hydrogen fuel cells only remain as an Eco-green marketing campaign topic for companies but nobody in the know expects them to be deployed in any significant way in the next 20 years, if ever. The economics just don't add up. Not even close.

I absolutely agree that the best path is Gas --> Hybrid --> Mild PHEV --> Strong PHEV

I very much agree with this but there is also room for pure battery EVs in parallel with the PHEVs for those who do not require the range everyday or are looking to purchase the EV as their second vehicle. The simplicity of an EV means that servicing costs far less than any vehicle with an internal combustion engine. Even up front costs could be lower once battery prices improve. It's not for everyone but their exists a large market that could happily use these vehicles.

Vehicles such as the Volt seem to have the right idea for everyone else. The vehicle travels most days purely on battery power but then uses a generator to extend the range whenever needed using commonly available fuel. When better technologies come along, the internal combustion engine used as the generator could be replaced with a fuel cell or some exotic high efficiency engine, or whatever makes the most sense in the given market (such as LPG in countries where it is widely available).

Also I think one thing a lot of people don't understand is that a hydrogen fuel cell vehicle is an electric vehicle just with a smaller battery and the electricity generated through a fuel cell. A lot of people seem unaware of the significant overlap in the technologies.

There is room for battery improvement but I fully expect cars to have diesel or even kerosene heaters in the northern countries. Like Russia, Nordic countries, Canada, large parts of US, Central Asia and so on. Of course it can be offset (mostly) by heating the cars while plugged in (will also help the batteries.) but that won't cover the full extent of it.

I have already written a few other posts under this article, but PHEV or plug-in series hybrid powered by natural gas / biogas powered generator is probably best for the environment and air in cities. Local pollutants and the laws against it is really what is driving this development any way. Just as it's does laws that essentially removed fossil fuels from my countries electric power production. It's not like natural gas resources are fully developed either. Neither is biogas from waste. Sweden should be able to support a large PHEV fleet on energy from waste. (For the extending range fuels). It will always makes more sense then trying to power normal ICE on biofuels here. Just the Ethanol for mixing into the gasoline here in Sweden requires as much wheat as Norway eat for human consumption/food. Or the wheat from 2-3 counties. Fodder/feed wheat which has a yield of 6-7 tons per hectare. That's slightly more then twice the yield US has...
