Fuel Cells

Fuel cell electric vehicles, Li-ion battery-powered cars, and carbon dioxide removal strategies all work to reduce global CO2 emissions. IDTechEx has a multitude of sustainability reports that give outlooks on the shared efforts of various sectors to reduce CO2 emissions in the air, to promote a cleaner way forward.

Electric buses are booming, with sales growing in Europe, America, India, and other key regions. Transport operators have shown themselves keen to electrify urban transport and cut greenhouse gas emissions. As emissions regulations tighten, city buses are likely to be all-electric within the next few years.

There is undoubtedly a huge push to build global DC fast-charging networks. The US government is providing more than $5 billion in funding and incentives as part of the NEVI program to build a coast-to-coast fast charging network, and many countries in Europe are rolling out similar programs following the AFIR regulations to spur EV charging infrastructure growth. 2024 will be a big year for EV charging, but, as IDTechEx discuss in this article, there's more to the story.

The US Department of Energy's paper, "Grid Operational Impacts of Widespread Storage Deployment" analyzes requirements to 2050. It variously calculates 1.3 TWh required to just over 6.0 TWh in its 94% renewable electricity, Zero Carbon scenario. Earlier, other researchers calculated 80% wind and solar will require 5.4 TWh of energy storage so it is obvious that huge amounts of storage are needed. Even that is with massive over-production and therefore curtailment - electricity only being generated 10% to 20% of the time on average. Polluting peaker plants only have 11% capacity factor so, on that model, bad replaces bad in that respect.

On the face of it, 2021 was a good year for fuel cell electric vehicles (FCEV) in passenger car markets. Toyota, with their second generation Mirai FCEV, and Hyundai, with their NEXO FCEV, both had record sales, which largely made up for Honda announcing in June 2021 that it had decided to pull the plug on production of their Honda Clarity FCV (citing the lack of hydrogen infrastructure and weak demand).

Fires in electric vehicles (EVs) certainly gain a lot of media attention in comparison to their internal combustion engine (ICE) counterparts. But a crucial question for the future of mobility is whether EVs are actually any more likely to catch fire than an ICE vehicle. There is always a non-zero risk of Lithium-ion batteries entering thermal runaway but the key points are how likely is a fire, how problematic is an EV fire and what is being done to prevent or limit them in the future?

IDTechEx Technology Analyst Dr David Wyatt has recently published a report update "Electric Truck 2020-2030", focusing on electrification in the medium and heavy-duty truck markets, providing a comprehensive set of market forecasts.

Few of the giant car makers have shown urgency in transitioning away from the internal combustion engine. What's more, the automotive market is set to decline once again in 2019 whilst electrifying newcomers made huge gains in front of sleeping incumbents' noses. Although a large fraction of this is orders (not deliveries), if OEMs do not wake up now, they never will.

Toyota and Daimler presented at a recent IDTechEx conference on their fuel cell vehicle programs. A questioner asked them to reveal the unique selling proposition of fuel cell vehicles. They said there is no USP.
