Will megawatt charging nix hydrogen gas cell tech in semis?

The Megawatt Charging Customary (MCS) formalized simply final summer time will pave the way in which for extra electrical huge rigs on the expense of hydrogen fuel-cell vans, an electric-truck guide predicts.

Enthusiasm for hydrogen fuel-cell passenger automobiles has largely performed out, and megawatt charging will do the identical for fuel-cell vans, Rustam Kocher, former Charging Infrastructure Lead at Daimler Vehicles North America, and now a guide, mentioned in a latest interview with Charged EVs.

Kocher is just not constructive about hydrogen, saying it is major function is to be “a method that the oil and fuel business can keep related.” Hydrogen may make the most of fossil-fuel business knowhow as a result of it may be pumped by means of pipelines and saved in tanks like oil and pure fuel, Kocher famous, however mentioned hydrogen gas cells are much less environment friendly than batteries and “extraordinarily costly.”

“Huge Oil’s received a variety of sources and cash to push this narrative” concerning the promise of hydrogen, Kocher mentioned. However he believes megawatt charging will “put a bullet in hydrogen” by matching its fast refueling time, which he views as hydrogen’s solely potential benefit.

“With MCS, it is the identical pace,” he mentioned. “Actually, it is likely to be quicker, so hydrogen can go pound salt.”

When introduced final summer time, MCS was mentioned to supply a “affordable” cost time for Class 6, 7, and eight business autos. These autos are anticipated to make use of very massive battery packs, requiring rather more energy for fast charging than the 350 kw that is at present the higher finish for the Mixed Charging Customary (CCS) utilized by passenger automobiles.

MCS goals to ship quick charging a package deal that, very similar to CCS, permits for charging stations to be appropriate with autos from totally different producers. Even Tesla, which went its personal method with passenger-car quick charging, has confirmed megawatt charging tech for each the Cybertruck and Semi, nevertheless it hasn’t signed on for using the cumbersome MCS connector.

Megawatt charging stations for vans current harder challenges for siting than these designed for passenger automobiles, nonetheless, as a result of they not solely must make room for larger vans however be at some extent within the grid that may assist an influence degree of 10 MW or extra.

One of many first such stations is Portland’s Electrical Island web site, developed by Daimler Vehicles North America (Kocher’s former employer) and utility Portland Normal Electrical. One other template would be the electrical truck cease deliberate by startup WattEV in Bakersfield, California, aiming for 40 charging stalls and 25 MW of solar-supplemented charging.

Maybe extra complicated although is that corporations which have championed MCS—like Daimler Vehicles—are additionally investing in hydrogen fueling. So it is honest to say the conflict between these applied sciences is not anyplace close to over but.
