“…The use of towpreg, where resin is impregnated into the carbon fibers in advance, is a viable option. Several studies have analyzed hydrogen pressure vessels made with towpreg [239,240]. However, the high cost [241] remains a challenge compared with the process advantages.…”

“…Another approach is to use low-density, low-cost resin [214,245]. The density of commonly used epoxy resin is 1.25 g/cm 3 , and when made into a composite layer, the density is 1.58 g/cm 3 [240]. By applying polyester, which is relatively low in density (1.25 g/cm 3 ) and cost, as the resin system [245] and manufacturing it into a full-sized tank, the resin requirement decreases by 6.08-8.7 kg, and the total weight reduction is 9%, which leads to cost savings for the hydrogen storage tank.…”

The most practical way of storing hydrogen gas for fuel cell vehicles is to use a composite overwrapped pressure vessel. Depending on the driving distance range and power requirement of the vehicles, there can be various operational pressure and volume capacity of the tanks, ranging from passenger vehicles to heavy-duty trucks. The current commercial hydrogen storage method for vehicles involves storing compressed hydrogen gas in high-pressure tanks at pressures of 700 bar for passenger vehicles and 350 bar to 700 bar for heavy-duty trucks. In particular, hydrogen is stored in rapidly refillable onboard tanks, meeting the driving range needs of heavy-duty applications, such as regional and line-haul trucking. One of the most important factors for fuel cell vehicles to be successful is their cost-effectiveness. So, in this review, the cost analysis including the process analysis, raw materials, and manufacturing processes is reviewed. It aims to contribute to the optimization of both the cost and performance of compressed hydrogen storage tanks for various applications.

“…The authors recognize the rising production figures for products such as composite pressure vessels and pipelines/tubes made of these towpregs as part of the ongoing energy transition. 4,5 Despite towpregs being commercially available, their gradual incorporation into existing composite materials production facilities is hindered by economic considerations and a lack of expertise in their characterization. The cost of carbon-fiber (T700 or equivalent) range between 50 and 130 €/kg.…”

In the field of textile technology, this study centers on towpreg—an integral component utilized in production techniques like tape laying and filament winding. Here, fibers are pre‐coated with resin, typically epoxy but not exclusively. Notably, towpreg retains a partially cured state, maintaining tackiness throughout the processing stages. The ultimate quality of the product manufactured with this towpreg is highly dependent on this initial material. This research highlights the importance of considering various factors that impact product quality. While not exhaustive, a systematic analysis of diverse towpreg parameters, including tack, resin content, and width, is provided. The work encompasses findings, challenges, and insights derived from towpreg manufacturing, incorporating the investigation of various experimental methodologies. The study also evaluates methodologies for laminated coupon production with towpreg, assessing their applicability in characterizing filament‐wound components. Although the article seems like a review, the authors aim to give a clear and holistic picture in one work instead of spreading information across many articles.Highlights Techniques for the quantification of towpreg tack are presented. Resin content distribution along towpreg length is presented. Towpreg width variation was investigated, seen to be one of the major causes for the gaps and voids in a filament wound composite. Coupon‐level characterization of towpreg through filament winding approach is presented. Other filament winding parameters influencing the quality of the manufactured composite are discussed.
