Hydrogen Car being Refueled

Where does HyGen obtain renewable electricity?

Power companies generate electricity by a variety of methods. Some of those methods are classed as renewable. These include electricity generated from solar, wind, wave, geothermal and small hydro (where available and environmentally developed). Tariffs can vary depending on the method of generation but, in California at least, renewable energy can be purchased and there’s an audit trail for how much is produced and sold.  

How far can a hydrogen FCEV travel on a full tank?

Range is dependent on several factors such as the size of the storage tanks, the pressure of the Hydrogen, power requirements of the engine and driving style. HyGen stations will dispense at 350 bar or 700 bar. 350 bar requires less energy and the cost per kilogram of hydrogen would be less. The customer can decide whether they wish to pay a premium for greater range. To quote a real world example: the range for the Hyundai ix35 is 369 miles.

How is a Hydrogen car refueled?

Refueling is almost identical to a gasoline-powered vehicle. There’s an additional locking-lever near the nozzle that must be engaged before fueling commences.

How long does it take to refuel a Hydrogen Fuel Cell Vehicle?

A trip to the station will be comparable to refueling a gasoline-powered vehicle with 3-5 minutes being typical.

What are hydrogen tanks in a FCEV made from?

Strong, lightweight carbon fiber.

How much does renewable Hydrogen cost?

Currently the market for hydrogen (as a transport fuel) isn’t sufficiently established. In addition, there are several methods of generating hydrogen and this can be done centrally or in a distributed model. HyGen plans to install 20 stations in Southern California using renewable electricity to generate hydrogen on site. The estimated cost of hydrogen at these facilities is expected to be less than gasoline on a GGE (Gallon Gasoline Equivalent) cost/mi. basis. 

When will Hydrogen cars be available?

They are available now in Southern California in limited quantities from companies like Honda and Mercedes. Mass produced vehicles are scheduled to be in showrooms in 2015.

How expensive are Hydrogen Fuel Cell Vehicles?

The government targets a figure of $30k/W for an 80kW fuel cell stack in order for light-duty FCEVs to be cost-competitive with equivalent gasoline cars. The most recently published analysis by the DOE estimates 2012 high volume manufacturing at $47/kW –  a >35% reduction since 2008 and >80% reduction since 2002—and well on the way to achieving the 2017 target of $30/kW. For 2015, expect the cost of a high performance hybrid

Fuel Cell Cost Estimates


Is a hydrogen car an electric vehicle?

Yes. Although, internal combustion engines can run on hydrogen, the most efficient use of energy is attained with a fuel cell to power an electric motor.

Are there really zero emissions from a FCEV?

That’s right. Water is the only emission from a hydrogen fuel cell electric vehicle.
