Toyota and DOE look at how hydrogen fuel-cell tech could help smooth the grid

Toyota introduced final week that it’s collaborating with the U.S. Division of Vitality and its Nationwide Renewable Vitality Laboratory (NREL) to offer a brand new proof level for hydrogen fuel-cell tech—in a megawatt-scale, multitasking power-generation bundle which may probably be used for renewable power storage and smoothing the grid.

The undertaking will embody a consideration of how hydrogen could be created with power from photo voltaic and wind sources, then saved, and used to generate electrical energy when wanted.

The three-year, $6.5 million undertaking is being funded by the DOE and is aiming to “construct, set up, and consider” a 1-megawatt proton trade membrane fuel-cell system at NREL’s Colorado campus. 

It is a part of the DOE’s [email protected] initiative, aiming “to advance inexpensive hydrogen manufacturing, transport, storage, and utilization.” It’s not as controversial because the hydrogen hubs, for trucking and extra, that had been written into the 2021 infrastructure regulation. 

As Toyota factors out, the system for the facility plant that shall be absolutely commissioned by the tip of the 12 months, generates about 15 instances the facility of a earlier NREL demonstrator. Or that is practically 9,000 instances the automotive-grade gas cell stack used within the Toyota Mirai. 

Along with the 1-mw fuel-cell generator, the undertaking features a 600-kg hydrogen storage system (greater than 100 instances the storage within the Mirai) and a 1.25-mw PEM electrolyzer. It’s half of a bigger NREL undertaking looking for to reveal “direct renewable hydrogen manufacturing, power storage, energy manufacturing and grid integration on the megawatt scale,” in line with Toyota.

With the undertaking, researchers additionally plan to discover new functions for the know-how and the way it would possibly combine with different techniques—probably in industrial makes use of, or to mix in powering heavy-duty gear. 

From this, sooner or later, such techniques could be used to strategically retailer and launch—with hydrogen—renewable power like photo voltaic and wind, instead of massive scale battery packs that might require extra uncooked supplies to construct. 

It’s working with techniques integrator Telios on the design of the plant, and so they plan to  “push the operational boundaries of the gas cell system design” to get an understanding of the restrictions and degradation.

Toyota, which hasn’t embraced battery electrical autos as quickly as different automakers, however like Hyundai it has continued to broaden its hydrogen fuel-cell plans for the U.S.—particularly pushing the tech into bigger autos. It has for years been utilizing fuel-cell semis for Southern California port responsibility, and in an enlargement of plans to make use of the tech for vehicles and industrial makes use of it introduced that it’s going to make fuel-cell modules within the U.S. beginning in 2023, in Kentucky. Toyota has even introduced that it’s growing hydrogen combustion engines for racing.
