Air Products and City of Santa Monica Open New Hydrogen Station; Fifth for the AQMD Hydrogen Prius Project

15 June 2006

A Series 200 fueling station.

Air Products, City of Santa Monica, Calif. and the California South Coast Air Quality Management District (AQMD) opened a new hydrogen fueling station located at the Santa Monica City Yards.

This is the fifth such station opened in support of a five-city AQMD hydrogen-fueling alternative energy demonstration program that features 30 Prius hybrids converted by Quantum to burn hydrogen in the engine. (Earlier post.)

The Santa Monica station uses an Air Products’ Series 200 system, a fully integrated vehicle fueling system, for the storage and dispensing of hydrogen with a capacity of 20-40 kg of hydrogen per day.

This model station provides flexibility in using hydrogen generated at the site, or delivered hydrogen, integrated with storage and dispensing capabilities.

On-site hydrogen at Santa Monica is provided to the fueling system from a production model HOGEN 6M Electrolyzer manufactured by Proton Energy Systems. Proton, a subsidiary of Distributed Energy Systems Corp., is a key supplier to Air Products, and the companies have a supplier arrangement for electrolyzer-based fueling stations.

The HOGEN 6M produces 6 Nm3/hr of hydrogen—12.94 kg/24hr—and consumes 6.8 kWh/Nm3 of power and 5.50 liters/hr of water (at maximum production rate) to produce that hydrogen. Hydrogen purity is 99.9995%.

For the AQMD five-city program, Air Products’ Series 200 systems are in operation at Santa Monica, Riverside and Burbank. Air Products’ HF-150 mobile hydrogen fueler is fueling vehicles at Santa Ana and Ontario.

"6 Nm3/hr of hydrogen"

What is an Nm3. A cubic nanometer? that would be an incredibly small amount

Normal cubic meter--the metric expression of gas volume at standard conditions, defined as being measured at 0° C and 1 atmosphere of pressure.

A cubic nanometer. Now that's going to get us on the Hydrogen Highway!! (sorry I couln't help have a chuckle...)

How many cars could be fueled in a daily basis assuming a 300 mile autonomy for those vehicles?

Well that depends on wha kind of h2 car they are talking about. Most h2 cars will be extremely eff hybrid designs that can prolly go 150plus miles per gallon equive of h2.

Porblem is I have no idea what a gallon equive IS:)

I do know an h2 car they showed awhile back had room for a max of 1.5 kg of h2.... so maybe 15 cars?

What's the feedstock? Methane?

Water.

On the Priuses used in the trial: the standard storage option holds 1.6 kg, and provides an effective hydrogen-fueled range of about 80 miles. The extended range storage option (2.4 kg) could kick that up to approximately 120 miles.

While water is the molecular feedstock for onsite hydrogen generation, electricity is the energy feedstock, so natural gas/hydro/nuclear/coal/renewables (in descending order) are the primary energy feedstocks in southern CA.

Additionally, the additional 27kg of hydrogen to be dispensed each day that is not generated onsite using the HOGEN 6M system is likely to be derived from methane reformation and transported to the filling station.

I’m wondering if the hydrogen station uses more energy than it creates? Assuming a Prius gets between 45 and 50 mpg of gasoline, and subtracting some well to wheel energy, does anyone know, 1, is it better than gasoline, and 2, does it take more energy to produce the hydrogen than you get back in miles traveled?

So if water is being used to create the hydrogen, where does all of the oxygen go? Does Air Products capture it for Oxygen tank supply sales?

re 1: at the current state of hydrogen infrastructure and fuel cell development, the well-to-wheels comparison of energy inputs vs. shaft work still favors gasoline and diesel by a significant margin.

re 2: please look up the 2nd law of thermodynamics on Wikipedia.

History repeats itself to an extent. Remember the CARB ZEV program. It was eventually killed by a concerted joint effort of automobile and oil concerns. The most visible outcome the GM EV-1, as well as Honda and Toyota electric vehicles were making great progress on extending usable range. Once the EV-1 switched from Lead Acid to more advanced battery packs, the driving range increased extensively. It seems the petroleum industry always finds a way to influence the various California air and energy regulatory boards. The Hydrogen experiment is just a red herring to extend the status quo that automobile and oil companies enjoy with the current ICE paradigm. It would be an interesting experiment to build a grass roots effort to bring back ZEV laws in California as well as other states. ZEV resulted in incredible innovations in electric vehicles that were available to consumers in under 5 years, as opposed to 25 years as promised by Hydrogen advocates.

The movie "Who Killed the Electric Car" is pre-screening now, and will be released in theatres over the next few months.

Unless the energy to produce this hydrogen comes from a clean source this is just bullshit.

Cleaning up powerstations and implementing more renewables should be way higher up the list of priorities than this.
