Hydrogen Is Worse for the Environment Than CO2, a New Study Finds

In case you are not aware, hydrogen as a source of energy has become controversial. It is promoted as a clean replacement for fossil fuels, without greenhouse gases at the tailpipe.

Even so, producing and storing hydrogen is energy-consuming, questioning its potential as a green solution.

Somehow Hydrogen is attractive to developers, but we were pointing out 30 yeares ago that you need to ultra compress it in hugely strong and expensive tanks, even then it will ALWAYS leak and the process may release more CO2 than you save .

(Totally neglected is NH3, ammonia where the nitrogen N stores the hydrogen H3 at minimum pressure. Buses ran on NH3 100 years ago, and nowadays it can be produced by electrolysis on green electricity, and it’s CO2 free oif course. The downside of NH3 is it’s toxic and it can produce NO when burned, which is WORSE than CO2 for the climate, though they say this can be avoided. see; https://co2freefuelexistsnow.wordpress.com/ )

-A new study shows that hydrogen has another big problem, as it becomes itself a greenhouse gas when released into the atmosphere. Long term, it might be 11 times worse than CO2 for the climate.

Light-duty vehicles have passed the phase when hydrogen can be a viable solution. Battery-electric vehicles have already proved better and gained traction with consumers.

But for other areas like maritime transport, heavy trucks, trains, and industrial applications, hydrogen still promises to be a clean alternative to fossil fuels. Not to mention being an almost drop-in replacement for other gaseous fuels like methane or propane.

Despite all its advantages, hydrogen also has drawbacks. The most important one: it’s very hard to produce hydrogen without creating greenhouse gases. Indeed, most hydrogen (around 95% as of 2020) is produced out of fossil fuels. The rest is obtained by water electrolysis using a lot of electric energy, which is also mostly produced by burning fossil fuels. So, yeah, either way, not quite green, unless the electricity is produced from renewable sources

But there’s another problem that scientists have overlooked. According to a new UK Government study, the hydrogen tanks all leak hydrogen, and the leaked gas is worse for the environment than the CO2. O

ver a 100-year time period, a ton of hydrogen released in the atmosphere will warm the Earth 11 times more than a ton of CO2. This is because hydrogen interacts with other gases and vapors in the air to produce powerful warming effects.

According to another study, compressed gas cylinders lose about 0.12-0.24% per day, while hydrogen transported as cryogenic liquid loses about 1% per day. This gets into the higher layers of the atmosphere, where it interacts with the same tropospheric oxidants that “clean up” methane emissions. This leads to increased concentrations of methane and the methane staying in the atmosphere longer.

The presence of hydrogen also increases the concentration of both tropospheric ozone and stratospheric water vapor, pushing the temperatures even higher.

Despite the new findings, even in the worst-case scenario where the hydrogen leakage rate gets to 10%, using hydrogen will offset a 4% carbon emissions reduction. This is still an enormous improvement over using fossil fuels. But the study “clearly demonstrates the importance of controlling hydrogen leakage within a hydrogen economy.”
