Traction fuel cells reach investment point on hype curve

Toyota, Nissan, Honda and Hyundai are all enthusiastic about the technology, whilst companies such as Yutong, GM, BMW, Daimler, Ford and Suzuki expecting traction fuel cells to comprise part of their future toolkits. Scepticism has been encountered from Volkswagen, Chrysler, PSA, Fiat, Mazda and Proton, whilst Tesla and BYD have expressed negative opinions regarding the technology.

Analysts at IDTechEx feel that it is particularly significant that, for use in open systems, electricity is ubiquitous - the more so with multiple forms of energy harvesting appearing on vehicles and their charging stations to produce substantial amounts of electricity. Hydrogen distribution will never be ubiquitous in private homes, though Honda has developed a small photovoltaic hydrogen-making station for vehicles.

Nevertheless, it is now, at the bottom of the hype curve, that prudent investment in the vehicle fuel cell value chain can be worthwhile. A large number of significant improvements are promised from viable green hydrogen to replacement of expensive platinum in the devices and some must surely be successful, mainly from 2020 onwards as the IDTechEx timelines in the report testify.

However, whereas there is great scope for consolidating the finished EV business, as Polaris Industries is proving with the highly fragmented industrial, leisure and commercial light EV sectors, there is only limited scope for consolidating the vehicle fuel cell business as yet. That is because technological change is accelerating and many fuel cells are made by vehicle manufacturers.

Dr Peter Harrop, Chairman, IDTechEx, believes: "Fuel cells will have significant, profitable use in a significant minority of vehicles by 2025, maybe a few percent. However, time waits for no one and a window of opportunity is closing: there is little scope for further slippage in timescales as pure electric alternatives are rapidly improving too and they are already successful in a huge variety of vehicles".
