US DOE to award $4M to support projects on hydrogen delivery technology for fuel cell vehicle refueling

The US Department of Energy (DOE) will award at least $4 million (subject to appropriations) (DE-FOA-0000821) to support research and development efforts for hydrogen delivery technology for fuel cell electric vehicle (FCEV) refueling. DOE’s long-term goal of production and delivery research and development (R&D) is a high-volume hydrogen cost goal of $2-$4 per gallon gasoline equivalent (gge) (produced, delivered and dispensed, but untaxed) to allow FCEVs to be competitive on a dollar per mile basis with gasoline in hybrid electric vehicles.

Delivery’s portion of that cost goal is $1-$2/gge hydrogen. The solicitation seeks to move technologies towards reaching that cost target by addressing the cost of hydrogen compression, storage, and dispensing at the fueling station. The funding opportunity announcement (FOA) identifies three topics of interest:

Forecourt hydrogen compressors for 700 bar gaseous dispensing. DOE is seeking applications for R&D at Technology Readiness Level (TRL) 4 or higher for the development of gaseous and liquid compression systems for the delivery of gaseous hydrogen at a minimum pressure of 875 bar to allow for 700 bar gaseous dispensing.

(To dispense hydrogen at 700 bar in the FCEV tank quickly, (i.e. to the SAE J2601 protocol) the pressure at the point of delivery must be at least 875 bar to ensure the required flow rate is achieved during the delivery.)

Applicable compressor technologies include, but are not limited to, diaphragm; reciprocating; centrifugal; advanced liquid pumps; screw; ionic liquid; electrochemical compression; and other alternative compression technologies.

Proposed compressions systems must be oil free or include, and sufficiently demonstrate, the ability to perform gas cleanup which results in hydrogen that is compliant with quality standards. Compression systems may include the integration of more than one type of compression but must meet targets for small compressors (i.e. on the order of 100 kg/hr) in order to enable cost competitive hydrogen delivery.

Applications must show a feasible pathway for the technology to achieve a throughput of 100 kg H2/hr at inlet pressures of 20 bar and an isentropic efficiency of at least 73%.

Deliverables of the proposed work must include cost analysis of the design and a demonstration of reliable delivery at ≥10 kg H2/hr. For the purposes of this FOA, the applicant needs to provide a plan to demonstrate a 2x improvement in lifetime compared to the current status of the proposed technology.

Integrated Intelligent Hydrogen Dispensers for 700 bar Gaseous Refueling of Fuel Cell Electric Vehicles. The integrated intelligent dispenser includes the hose, meter, and control system necessary to delivery hydrogen safely per the SAE J2601 Technical Information Report (TIR) using a Type A dispenser for fast-fill capability. Intelligent controls should allow the dispenser to adapt to other fill methods as necessary.

DOE is encouraging proposals which include the development of innovative, low-cost components for robust communication to replace the current IR technology are encouraged. The dispensing accuracy must reach at least 5% over the full range of operation; the conditions range from -40 °C to +85 °C, at flow rates between 2 - 60 g/s and at service pressures up to 875 bar. Designs are encouraged which exceed the 5% target and move the technology toward meeting the 1.5% system accuracy and other requirements as defined in NIST Handbook 44.

Designs must be developed to be compliant with SAE J2600, SAE J2799 and other applicable refueling and dispenser standards. The dispenser must also be capable of refueling vehicles to the J2601 TIR Type A fills and able to maintain the fuel quality to meet the SAE J2719 standard.

In addition to the development and prototyping of the new dispenser technology deliverables of the proposed work must include the demonstration and verification of the dispenser’s ability to communicate with vehicles during fills and to provide robust dispenser operation during back-to-back fills at -40 °C and 875 bar.

DOE encourages proposals which demonstrate the potential of the proposed dispenser design to meet the technical requirements and to meet the 2015 dispenser high volume capital cost target of $40,000. Designs which do not advance the technology beyond the current capability and designs which use infra-red communication are discouraged.

Forecourt hydrogen storage at 875 bar or greater. DOE will consider designs which are projected to meet the DOE cost targets of <$1,000/kg H2 stored at pressures of 875 bar or greater. Projects proposing high pressure tube trailers that will remain onsite at the forecourt will be considered provided they are also projected to meet 2020 cost and pressure targets for tube trailers.

The storage system refers to the storage vessel and any required peripheral components (e.g. valves, fittings, heat exchangers (if applicable), etc.). The scalability and footprint of the storage system should be considered for versatility in applications. The storage system should ideally be applicable to various forecourt locations, such as urban forecourts, rooftops, and underground storage.



Is it dangeurous these tanks in fuelcell cars and suvs?


Dangerous .... in relation to gas and/or NG tanks and large battery packs? Not necessarily or inherently more so?


I would develop adsorbants to carry H2 at 1000 psi rather than 10,000.


It will sooner than many expect.


Just look at all the wiggling, squirming and thrashing about DOE is doing. At least they are only wasting 4 million on it this time.

Rather than generating pure Hydrogen and have all the handling, storage and transportation problems that come with it, why don't we just combine it with some other element to make a safe material that won't have all of pure H's problems.

What would be a good one?

Lots of good candidates. Methane and methanol are obvious.

Ammonia is a good one, too: no need to find carbon, as nitrogen is right there in the atmosphere (carbon is too, of course, but at much lower concentrations which are a bit annoying to deal with).


Methanol and DME are good. Diesel hybrid DME makes good buses and trucks that are cleaner and more efficient.


pissing away money


$4 million won't even cover routine monthly maintenance for one of 50 B2 bombers, who is "pissing" what away?

Successful implementation of H2 as a fuel in daily transportation, a most permeating gas that can go through even many metals, at incredible pressures of 700 bar, rarely used in the a testament to the ingenuity of human. Yet, it is happening, scheduled to arrive by a 7-11 near where you live, eventually.

The DOE has increasingly raised the bar higher and higher in giving out awards. This is a testament to the rapid advancement of H2 technologies and programs and projects. THe motivation for all this is clear: H2 is the most efficient and least expensive synthetic fuel to make, as well as being the cleanest.

A H2 fuel tank at 700 bar is practically bullet-proof, unlike a lithium battery that can burn or explode if hit by foreign debris, like what's been happening recently. The H2 tank will remain intact even in collisions so severe that no one can survive, unlike a gasoline tank that often explodes on often survivable impacts. The H2, if leaked from a cracked tank or ruptured piping, will immediately fly skyward, being such a light gas of extreme buoyancy, instead of hanging around and burn up everything around.


Don't forget that Hydrogen is not a fuel.

Roger Pham

Huh...H2 is not a fuel? Stuff that you put in a tank in your car to power it, to combine it with O2 to provide energy...Then, what is a fuel?


From Wikipedia


Once manufactured, hydrogen is an energy carrier (i.e. a store for energy first generated by other means).The energy can be delivered to fuel cells and generate electricity and heat, or burned to run a combustion engine. In each case hydrogen is combined with oxygen to form water. The heat in a hydrogen flame is a radiant emission from the newly formed water molecules.



Under that analysis petrol and coal are also just energy carriers, not fuel, as both consist of energy first generated by other means, ie solar and photosynthesis.

The distinction you are seeking to make between a fuel and an energy carrier is one without any meaning.


I am not making this shit up. What I reference here is widely accepted by science. I will not argue this with anyone here. Do your homework.
