US DOE to award $4M to support projects on hydrogen delivery technology for fuel cell vehicle refueling
16 November 2013
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.
