Opportunity Summary:
The U.S. Department of Energy (DOE), through the Fuel Cell Technologies Office (FCTO) within the Office of Energy Efficiency and Renewable Energy (EERE), issued this Request for Information (RFI) to gather input on how to reduce cost and improve performance of 700 bar compressed hydrogen storage systems used onboard vehicles. The focus is on composite overwrapped pressure vessels (COPVs), which are the dominant technology for high-pressure hydrogen tanks in current fuel cell electric vehicles (FCEVs). DOE is looking for practical strategies and longer-term research pathways that could help meet future hydrogen storage system cost targets and make light-duty FCEVs more commercially viable.
The RFI centers on Type III and Type IV COPVs. Type III tanks use a metallic liner with a composite overwrap, while Type IV tanks use a non-metallic (polymer) liner with a composite overwrap. Both tank types typically rely on carbon fiber reinforced polymer (CFRP) composites because carbon fiber provides the high strength-to-weight performance needed to safely store hydrogen at up to 700 bar. DOE highlights that, despite successful deployment in market vehicles, the current high cost of these systems remains a major barrier to broader adoption, especially in light-duty applications where cost sensitivity is high.
A major portion of the RFI is aimed at cost reduction pathways for the tank components, especially the composite materials. DOE is explicitly seeking ideas related to lower-cost carbon fiber precursors, cheaper and more efficient carbon fiber conversion/production processes, and potential alternative fibers that could substitute for carbon fiber while still meeting pressure vessel requirements. The agency is also interested in innovations in polymer resins and resin additives, since matrix materials and processing choices affect both performance and manufacturing cost. Beyond the composite overwrap, DOE is also asking for strategies to reduce costs in other key components such as liners and bosses (the fittings/ports and structural interfaces that connect the tank to the fuel system), including alternative materials and designs that could simplify manufacturing or improve durability.
In addition to cutting material and component costs, DOE is seeking approaches that improve overall system performance in ways that reduce how much expensive composite is needed in the first place. This includes concepts that increase structural efficiency so the tank can achieve required capacity and safety with less carbon fiber, as well as new designs that improve conformability and packaging. Conformable or better-packaged storage concepts matter because onboard tanks must fit within vehicle design constraints; improved packaging efficiency can increase usable hydrogen capacity without simply adding more high-cost material. DOE also invites ideas that could lower operating costs and improve refueling performance, including design improvements that might reduce or eliminate the need for hydrogen pre-cooling during fast fills, which is currently used to manage temperature rise during compression and protect tank limits.
The purpose of the RFI is planning and strategy development rather than awarding funding. DOE emphasizes that this notice is not a Funding Opportunity Announcement (FOA), so it is not accepting grant applications. Responses are intended to help DOE identify promising research and development directions it might pursue in the future, and DOE may or may not issue a related FOA later. Submitting a response provides no competitive advantage or disadvantage if a future FOA is released, and any future funding would depend on Congressional appropriations and program direction.
From an administrative standpoint, eligibility is listed as unrestricted (open to any type of entity, subject to any additional clarifications in the full notice). DOE states that information received will be used on a non-attribution basis for government planning, respondents will not be reimbursed for preparation costs, and DOE is not obligated to acknowledge receipt or provide feedback. Responses had to be submitted by email to H2Storage@ee.doe.gov by 5:00 PM Eastern Time on June 30, 2016, as Microsoft Word (.docx) attachments, limited to five pages with standard formatting (12-point font and one-inch margins). Attachments over 25 MB were recommended to be compressed for delivery. The full RFI was posted on the EERE eXCHANGE website under Funding Opportunity Number DE-FOA-0001596 (CFDA 81.087), categorized under Energy and listed as a discretionary opportunity with an “Other†funding instrument type, reflecting its information-gathering nature rather than a direct grant competition.
