EV batteries are not efficient for storing energy in the long term because of the huge amounts of materials that go into them. > using that electricity to charge EVs is still orders of magnitude MORE EFFICIENT

However, the technology is developing rapidly, from Toyota’s portable canisters to hydrogen pastes and advanced aluminium fuel pucks.

EVs are getting better than ever, and hydrogen production typically involves more fossil fuels than you might expect. It’s hard to see Toyota’s vision from the present day. With these hydrogen canisters, Toyota “envisions hydrogen evolving into a familiar, broadly-used form of energy.” It’s invested big in hydrogen cars, and still lags behind its competitors when it comes to battery-electric vehicles. Toyota has big hopes for hydrogen as a fuel of the future. Instead, charging up a bunch of canisters makes it easy to move hydrogen around to where it’s needed. Unlike liquid fuels, hydrogen can’t easily be poured from one tank to another. The general idea is that the canisters are an easy way to deliver hydrogen energy in a portable format. The cartridges take a difficult and fussy fuel and put it into a no-mess, no-fuss format. There, they will be used to run a “broad range of daily life applications in and outside of the home.” Potential applications could be running hot plates at an outdoor picnic, or providing lighting for a campground without the noise of a combustion-engine generator.

The canisters will be tested in Toyota’s Woven City, a future-looking “smart city” in Japan that hopes to trial new technologies. Instead, it appears Toyota sees the canisters as a way to deliver clean electrical power in a more weight-efficient format than using batteries. 3.3 kWh might run your electric scooter for a decent long ride, but you’d need to have a fuel cell and a 5 kg canister hanging off it, somehow. Most electric cars have batteries exceeding 70 kWh in capacity it would take over 18 such canisters to provide the same amount of power.

Toyota demonstrated a twist-and-lock insertion method for the hydrogen canisters which feels very futuristic indeed.Įven better is if the machine sucks them in automatically like those magic Macintosh disk drives of the 1980s. Even given the fancy plastic casing, it’s still better than lithium-ion batteries, which come in around 260 Wh/kg at best. While it’s not a lot of power, the total capacity works out to roughly 660 Wh/kg. Regardless, the press release notes that this is derived from a typical capacity of 3.3 kWh when the canister is used with a “typical FC system.”

One cartridge should generate “enough electricity to operate a typical household microwave for approximately 3-4 hours.” Given microwaves are typically operated in minutes at a time, one suspects the TV dinners at Toyota HQ may be more than a little frazzled. Toyota discusses the canister’s power output with a curious metric.

They come in much lighter than a typical tank of propane (~30 kg) or a full jerry can of gasoline (~25 kg). Thus, the canisters can readily be manipulated and carried by a single person, serving as a lightweight store of energy. The target weight for the canisters is 5 kg. Footnotes from Toyota indicate they rely on a “high-pressure hydrogen tank,” suggesting storage in gaseous form. The dimensions of Toyota’s attractive round canisters are quite compact- 400 mm long and 180 mm in diameter. It’s commonly stored as a compressed gas or liquid, or within solids in special metallic forms. Thus materials must be selected carefully to store hydrogen safely. This can cause problems, such as leaks, or hydrogen embrittlement in metal components. Molecules of H2 are so small that they tend to leak out of most containers, finding a way to slip between other molecules.

The company’s latest efforts involve a toteable hydrogen cartridge – letting you take hydrogen power on the go! Toyota has been pushing hard for hydrogen technology, and has worked to develop vehicles and infrastructure to this end. It’s also been put forth as a replacement for everything from natural gas supplies to laptop batteries.

When used in fuel cells, the only emissions from its use are water, and it eliminates the slow recharging problem of battery-electric vehicles. Hydrogen has long been touted as the solution to cleaning up road transport.
