After years of promises, hydrogen-powered vehicles are finally arriving on the scene.

Toyota has finally released its vision of the future, 20 years in the making!

With several starts and stops over the last 20 years or so, hydrogen fuel cell vehicles (FCVs) are finally hitting the roads.

The real competition for green tech is not other green tech, but the old, dirty incumbents.

Hydrogen is abundant in water and full of energy. We just need a cheap way to get the hydrogen where we need it.

Goodbye car ownership, hello "mobility as a service."

They are not efficient, there is no infrastructure, and they are shills for the fossil fuel industry.

In a bid to highlight the clean air advantage of the Toyota Mirai, a hydrogen fuel cell electric car, the company is putting up pollution-scrubbing billboards.

The forthcoming Tri-Gen facility is being called "the world's first megawatt-scale 100% renewable power and hydrogen generation station."

The unique paint could provide clean power to homes at a low cost.

They actually might in certain cases, using off-peak power at peak times.

The technology could lead to cheaper hydrogen cars in the future.

E-bikes will eat cars, and H2 bikes will eat Toyotas.

BMW has built the first of their Hydrogen 7 cars for public use, and handed the first set of keys over to US funny-man, Will Ferrell. 25 of the first 100 cars will be handed out to celebrities in order to promote their hydrogen cars in a predictable PR

Hydrogen trains are now running in Germany. But are they really green and do they make any sense?

Stanford scientists figure out a way to get hydrogen out of seawater. Does this matter?

In two words: It's not.

Yes, in theory. Doing it in practice is a whole other story. This is another example of how the hydrogen economy is a fantasy.

So many flavors and colors of gas these days. They are all problematic.

New technology might actually pull hydrogen out of the Alberta tar sands and leave the carbon behind.

Everybody is hopping on the hydrogen train, but it's being driven by natural gas.

The only people who benefit from the hydrogen economy are the oil and petrochemical companies that make the stuff.

It could move goods, transport hydrogen, reduce CO2 and water the lawn all at once.

Hydrogen was used instead of liquefied petroleum gas.

Schemes to look at cutting emissions in sectors such as transport in push to meet 2050 ‘net zero’ target

Researchers at the University of Chicago used data from the Spitzer telescope to examine the planet, called KELT-9b, and find out just how inhospitable it is.

Professor Sara Seager from the Massachusetts Institute of Technology (MIT) believes astronomers should broaden their horizon's as they scan the cosmos for signs of life.

Hydrogen has long been touted as a clean alternative to fossil fuels. Now, as major economies prepare green investments to kickstart growth, advocates spy a golden chance to drag the niche energy into the mainstream of a post-pandemic world.

A new research paper suggests that life forms, if occurring in other planets, do not need to be similar to what we know of them on Earth.
