''Blue'' hydrogen typically refers to hydrogen which has been made using methane or other carbon-based gases. The carbon dioxide produced is then captured ready for long-term geological storage.
Another difference is economic. Blue hydrogen has a lower initial production cost due to the use of hydrocarbons, among other reasons; green hydrogen has a higher production cost for the time being, but the development of new green hydrogen plants and the convinced commitment to the generation of this element means that, little by little, the
Blue hydrogen is often touted as a low-carbon fuel for generating electricity and storing energy, powering cars, trucks and trains and heating buildings. An icon of a desk calendar. An icon of a
Blue hydrogen. Blue hydrogen is produced mainly from natural gas, using a process called steam reforming, which brings together natural gas and heated
The process of making blue hydrogen requires a lot of energy. For every unit of heat in the natural gas at the start of the process, only 70-75% remains in the hydrogen product. In other words, 25% more natural gas would be needed to make the blue hydrogen used to heat a building than just using the natural gas instead.
Blue hydrogen can be clean — if it''s able to restrict its methane emissions and successfully capture 95 percent of the carbon emissions from producing the hydrogen. That isn''t achievable.
In 2020, of all the low-carbon hydrogen produced, 95% of it was blue, according to a recent report from the IEA. But by 2050, as the green-hydrogen industry develops, it should be more
Blue Hydrogen. The same chemical processing technique used to make gray hydrogen is also used to produce blue hydrogen. The big difference, however, is the management of CO2. With blue hydrogen, the CO2 produced does not escape into the environment. Instead, it is captured at the production facility and stored separately.

Hydrogen, a colorless, odorless, tasteless, flammable gaseous substance that is the simplest member of the family of chemical elements. The earliest known chemical property of hydrogen is that it burns with oxygen to form water; indeed, the name hydrogen is derived from Greek words meaning ''maker of water.''.
There are two ways to move toward cleaner hydrogen production. One is applying carbon capture and storage to the fossil fuel-based hydrogen production
Blue hydrogen differs from gray hydrogen in that, with blue hydrogen, some of the carbon dioxide released by the SMR process is captured. In another version
Blue hydrogen is produced using the same reforming process that is used to create grey, brown and black hydrogen, but the
blue hydrogen production. Large-scale production of low-carbon hydrogen (known as blue hydrogen) is an important step towards reducing global carbon dioxide emissions. The technology is comparable with today''s grey hydrogen production from fossil fuels but includes additional carbon capturing and sequestration (CCS) to permanently remove
Only a tiny percentage of hydrogen produced today is green; in fact, all low-carbon types of hydrogen (that includes blue, pink, yellow, turquoise, and aqua) account for less than 1% of global
On average, the cost of hydrogen produced via ATR with CCS was only €0.02/kg more expensive than unabated SMR in the Netherlands over the second quarter, and €0.10/kg more expensive in the UK, according to ICIS calculations. This represents a continued decline from the €0.04/kg and €0.16/kg premiums identified in the Netherlands
''Blue'' hydrogen typically refers to hydrogen which has been made using methane or other carbon-based gases. The carbon dioxide produced is then captured ready for long-term geological storage.
What role will blue hydrogen play in decarbonizing the world''s energy systems? MIT Energy Initiative Research Scientist Emre Gençer discusses findings from research analyzing the climate impacts of
A fuel without a future. Despite industry claims, blue hydrogen — which is made from methane, a climate pollutant — is not the fuel of the future. Here''s why: The cost of blue hydrogen production is tied to volatile gas prices; Its production relies on costly carbon capture technology that has failed to meet the industry goal in real
Blue hydrogen starts with converting methane to hydrogen and carbon dioxide by using heat, steam and pressure, or gray hydrogen, but goes further to capture some of the carbon dioxide. Once the byproduct carbon dioxide and the other impurities are sequestered, it becomes blue hydrogen, according to the U.S. Department of Energy.
However, both blue and green hydrogen meeting the proposed definitions would benefit from the Package''s proposed dedicated hydrogen infrastructure and market outlined below at least until 2030. The expectation is that by 2030 the EU will introduce a stricter GHG reduction threshold for the definition of low-carbon ("blue") hydrogen.
The colours of hydrogen. Hydrogen has many colours, and we frequently refer to green, turquoise, blue and grey hydrogen. Since this versatile energy carrier is actually a colourless gas, one might well ask what these colours actually mean. We show what colours hydrogen is classified as, what the meaning behind these colours is, and how they are
Blue hydrogen is primarily produced from natural gas using the Steam Methane Reforming (SMR) technique. This method generates hydrogen and emits carbon dioxide as a by-product. To mitigate its environmental impact, Carbon Capture and Storage (CCS) is employed. While this method substantially reduces greenhouse gas emissions,
The UK has made life a little easier for blue hydrogen producers by choosing to use a global warming potential (GWP) of 100 years in its calculations. The GWP100 for methane is 29.8, according to the latest IPCC report — meaning it is 29.8 times more potent a greenhouse gas than CO 2. By contrast, if a 20-year GWP was used, that
Mature carbon capture technologies can remove 95% of CO 2 in blue H 2 production. Hydrogen is expected to play a key role in the world''s energy-mix in the near future within the context of a new energy transition that has been ongoing over the past decade. This energy transition is aiming for hydrogen to meet 10–18% of total world
Blue hydrogen in a low-carbon energy future. The energy industry is rising to the challenge of a hydrogen economy. For many, it is essential to a clean energy future. Hydrogen can be produced in several ways, but if it is to help in the battle with climate change, the hydrogen produced will need to be low carbon.
Blue hydrogen is hydrogen produced from natural gas with a process of steam methane reforming, where natural gas is mixed with very hot steam and a
Blue hydrogen remains cheaper than green in all scenarios and is the only form of hydrogen that directly reduces CO2 emissions. There is enough natural gas to last for years, and residual gases from refining or biogas, for example, can be split into hydrogen and CO2 in the same way. However, it is expected that towards 2050, the supply of green
Hydrogen is a chemical element; it has symbol H and atomic number 1. Hydrogen flames in other conditions are blue, resembling blue natural gas flames. However, in all likelihood, "sulfureous" should here be
Production Process: Green hydrogen''s production is entirely clean, leveraging renewable energy for water electrolysis. On the other hand, blue hydrogen is derived from natural gas, with carbon capture technology reducing but not entirely eliminating its carbon footprint.
Blue hydrogen from fossil sources coupled with carbon capture and storage (CCS) is a more ambiguous option and requires further evaluation: Due to its fossil fuel supply chain, it is often regarded as unfit for climate neutrality or is only assigned a transitional role [5]. The different stances on eligible hydrogen pathways are highlighted
Next on the spectrum is blue hydrogen. Blue isn''t all that different from gray (womp womp) in that it is produced using fossil fuels. What sets the two apart is the capture and storage
But what does this decision mean for the UK''s blue hydrogen ambitions, One of these was the Grangemouth refinery, owned by British chemicals giant Ineos, which plans to develop a blue hydrogen plant based on transporting and storing emissions to Acorn''s site 2.5km under the North Sea.
What does all this mean for the cost of green hydrogen in Europe? First, that it may indeed take more time for the cost of green hydrogen to come down to levels near those of grey and blue hydrogen. The scale-up of electrolysis needs to drive down the cost. Even more critically, mass production will require large volumes of cheap green
