With battery electrical automobiles (BEVs) charging into the worldwide market, it’s clear to see that the long run is certainly electrical. That being stated, there are fairly lots of people who’ve acknowledged the potential of hydrogen power – each in the case of utilizing it as a gasoline cell to energy electrical automobiles, in addition to a gasoline supply for internal-combustion engines.
We’ve talked about fairly a number of hydrogen-focused initiatives from the likes of Yamaha and Fraunhofer IWU. This time round, it’s the Massachusetts Institute of Technology who’s showcased its hydrogen-powered initiatives. MIT’s Electric Vehicle Team has lengthy had expertise in the case of constructing and racing modern electrical automobiles. This time round, the group is popping its eye to the two-wheeled world, and is venturing into hydrogen-powered electrical bikes in 2024.
MIT’s Electric Vehicle Team is conducting rigorous testing on a hydrogen electrical bike prototype.
Back in October 2023, MIT’s EV group carried out a profitable demonstration of its hydrogen-powered prototype. To make issues even higher, the group isn’t protecting the prototype all to itself. The new hydrogen-electric machine was designed as an open-source prototype, with all of the plans accessible on-line. This signifies that improvement can proceed and department out as different parts may be put in and additional experimentation may be carried out on the prototype.
The total challenge is spearheaded by Aditya Mehrotra, a graduate pupil working with Alex Slocum, a mechanical engineering professor. Mehrotra has been specializing in power methods, and can be a motorbike fanatic, and so he got here up with the concept of a hydrogen-powered electrical bike. The group defined that whereas batteries have superior leaps and bounds lately, they nonetheless have their limitations. One of the most important limitations is their charging time, with even the quickest chargers at this time taking a number of minutes to juice up a battery. Meanwhile, refueling with hydrogen might, theoretically, be as fast as filling up a fuel tank.
The hydrogen-powered electrical bike works equally to a battery electrical bike with a variety extender.
So how does all of it work? In a video uploaded to MIT’s official YouTube channel Mehrotra explains that the hydrogen bike works equally to a battery electrical bike with a variety extender. There’s a motor that drives the wheel, and a motor controller that converts DC energy into AC energy for the motor. This controller will get energy from a battery and provides it to the motor to show the wheel. Pretty easy, proper? The hydrogen system right here works in parallel with the battery, appearing like a charger. As such, because the bike drives alongside, it depletes the battery which in flip, is constantly recharged by the hydrogen gasoline cell.
Mehrotra explains that so long as the typical energy output of the battery is decrease than the typical output of the hydrogen gasoline cell, the battery by no means drains cost. When the gasoline cell is depleted, it’s so simple as changing it with a brand new one, one thing that takes a number of seconds or a few minutes at most.
MIT’s Electric Vehicle Team has taken some big strides previously, because the challenge was offered at Hydrogen Americas Summit and can be deliberate to be showcased on the World Hydrogen Summit. The prototype additionally made an look on the Consumer Electronics Show, one of many largest expos in Las Vegas, Nevada, meant to showcase improvements on this planet of electronics – EVs included.
Naturally, the following step could be to push the restrict of what hydrogen technology is able to. Indeed, Toyota has a hydrogen-powered electrical automotive referred to as the Mirai, though it has struggled to achieve mainstream recognition due to the shortage of infrastructure surrounding hydrogen. As such, it’s a part of MIT’s EV group’s purpose to extend demand for hydrogen so extra infrastructure and know-how surrounding hydrogen may be developed. The group hopes that sooner or later, fossil fuels may be fully changed by hydrogen, all whereas offering the identical stage of effectivity and comfort as gasoline.
Battery Electric Vehicles (BEVs) have taken the world by storm, however their reign just isn’t absolute. Croatian hypercar producer, Rimac, is peering right into a future the place batteries are out of date, changed by a revolutionary expertise: liquid-fueled electrical energy era utilizing nanotubes.

More Efficient Compared To Traditional Gasoline Engines
Rimac
While the liquid-fueled nanotube technology remains in its early stages, its potential for effectivity surpasses conventional gasoline engines. Estimates counsel it may obtain as much as 80% gas effectivity, in comparison with the typical 20-30% for gasoline engines. This interprets to considerably much less gas consumption and probably longer driving ranges. However, it is necessary to notice that these are theoretical projections, and precise effectivity might differ relying on elements like gas sort, working circumstances, and manufacturing scale.
Implications For Zero-Emission Goals
While the expertise guarantees elevated effectivity, its environmental affect stays a important query. The emissions profile will rely closely on the particular gas used. Utilizing renewable fuels like hydrogen or biofuels could significantly reduce CO2 emissions in comparison with gasoline. However, if fossil fuels are employed, the emissions may nonetheless be greater than electrical autos charged with renewable power. Further analysis and improvement are essential to optimize the expertise for minimal environmental affect.
Lighter And More Powerful Electric Vehicles

Rimac’s latest exploration of liquid-fueled nanotube expertise for EV powertrains is a major instance of this forward-thinking strategy.
In the first six months, 321,600 all-electric vehicles (BEVs) were handed over to customers, compared with 217,200 in the same period last year
In Europe, the Group is the market leader in the BEV segment and gained market share, with deliveries increasing by 68 percent to 217,100 vehicles (H1 2022: 128,900)
Order bank in Western Europe remains good at around 200,000 BEVs
Hildegard Wortmann, member of the Group’s Extended Executive Committee for Sales: “With an increase in all-electric deliveries of around 50 percent in the first half of the year, the Volkswagen Group is systematically continuing its transformation. We are the market leader in Europe in this segment and have gained market share. Since May, we have again seen an improved trend in incoming orders here, after a certain reluctance on the part of our customers at the start of the year due to reduced subsidy programs, partly long waiting times and high inflation. In view of the recent significant reduction in delivery times, we expect this positive trend to continue in the coming months.”
The Volkswagen Group increased its deliveries of all-electric vehicles (BEVs) by 48 percent year-on-year to 321,600 vehicles in the first half of the year. The BEV share of total deliveries rose to 7.4 percent, up from 5.6 percent in the first six months of the previous year. The Group achieved the highest growth in Europe, where deliveries rose by 68 percent to 217,100 BEVs. Here, the Volkswagen Group is the market leader and gained market share. Significantly more customers of a Group brand took delivery of their all-electric vehicles in the USA, too. The increase here was 76 percent to 29,800 vehicles. In China, deliveries were around two percent below the previous year’s level at 62,400 BEVs in a particularly competitive market environment. Recently, however, the trend here has also been positive. Following a lower first quarter, 18 percent more BEVs were handed over to customers in the world’s largest automotive market in the second quarter than in the prior-year period. Worldwide, the increase in the second quarter was 53 percent to 180,600 vehicles (118,000), and the BEV share of total deliveries rose to 7.7 percent (6.0) in this period.
Around 68 percent of the Group’s BEV deliveries were in its home region of Europe, followed by China with 19 percent and the USA with nine percent. Four percent went to other markets.
