As we barrel towards an EV and autonomous future, one piece of interesting engine tech gets short shrift: hydrogen. It's the simplest and most abundant element in the universe; it would be nice if we could use it for powering our lives. But unfortunately, there are only two hydrogen cars on the roads today: the Toyota Mirai and Hyundai Nexo.

Both companies are looking at the fuel for future vehicles, but it's Hyundai that will be the one hosting the online Hydrogen Wave Global Forum on September 7. The Hyundai Motor Group will showcase its plans for a future hydrogen society, "including breakthrough hydrogen mobility ideas and technologies." It certainly sounds interesting, and we'll be watching to bring you the news.

Hyundai published three short teasers about the event on its YouTube channel. The first shows a hydrogen-powered race car tearing up the track. The second shows a semitruck, we're guessing hydrogen-powered with script saying, "with a single charge of hydrogen, a long journey of freight begins." The third is a quick clip showing all of the places you can fill up with H.

The online forum lands on the 'International Day of Clean Air for Blue Skies', an annual September 7 event that was proposed by South Korea and ratified by the United Nations. After the forum, a physical exhibition will take place in Goyang, South Korea from September 8-11.

Hyundai says it will show off "state of the art fuel cell electric vehicles" at the show, as well as other applications. We'll also get presentation and products from its affiliates, "further showcasing and detailing how a hydrogen society can be formed and realized."

We're sure we'll hear about its Nexo, is the only hydrogen fuel cell crossover for the US market. It has a range of 380 miles to go along with its 161 hp and 291 lb-ft of torque. It's only sold in California for now, as the state has the one of the country's best hydrogen infrastructures. We've driven a few of these hydrogen cars, including the Nexo, and found them to be perfectly adequate daily drivers. Maybe Hyundai can convince a few more buyers next month, as it's currently offering huge discounts on the slow-seller.
