China's hydrogen production capacity is about 40 million tons per year, and the output is about 33 million tons per year. However, most of the hydrogen is produced from fossil fuels or industrial by-products, which is regarded as grey hydrogen. Specifically, nearly...
But Liebreich continued to press that direct hydrogen fuel would never work in aviation simply due to logistics, which he described as “a priori absurd”. “Even if you took those planes and wanted to fill them with hydrogen, you would need to have 2.7GW of power going into Heathrow [jus...

hydrogen. Carbon emissions generated during this process are captured and stored, rather than being released into the atmosphere. This makes blue hydrogen a lower-carbon alternative to traditional grey hydrogen where the emissions are not captured, though it still produces some carbon emissions whe...
“Brown” hydrogenrefers to hydrogen extracted from brown coal (and “black” hydrogen from black coal), while “grey” hydrogen uses natural gas as the source. When using these fossil fuels, hydrogen is stripped from the hydrocarbons using steam or oxygen (in a process known as reforming), ...
Hydrogen from these technologies is often associated with the respective colors grey, blue, turquoise, and green. The critical comparison of the technologies is objectified and quantified based on the methodology of life cycle assessment. For this purpose, the environmental impacts of the hydrogen ...
Hydrogen is a promising energy carrier and feedstock alike for decarbonizing the energy, transport, and chemical sector and mitigating the effects of global warming. Identifying and realizing environmentally friendly hydrogen production pathways is, however, significantly impeded by the need for step-wis...
However, green steel will not become cheaper than coal-based grey steel in China until “sometime close to 2040”, Rethink says, due to the low price of domestic coal. The $433bn Inflation Reduction Act of 2022 creates a tax credit that would pay clean hydrogen producers up to $3 per ...
Grey hydrogenis made from natural gas reforming like blue hydrogen, but without any efforts to capture carbon dioxide byproducts. Pink hydrogenis hydrogen made with electrolysis powered by nuclear energy, which does not produce any carbon dioxide emissions. (Although nuclear energy createsradioactive ...
but those are still small compared to current grey hydrogen production plants. Second, building the infrastructure for large scale hydrogen use, such as pipelines or export/ import terminals, will take many years—it takes seven to twelve years to plan and build a pipeline, for example. Ideally...
