What is gray, blue and green hydrogen?
There are three variants of hydrogen production. Gray hydrogen is made with oil, gas or coal. This process produces hydrogen, but it also releases CO2. Because CO2 emissions have a negative impact on the climate, this is the most polluting form of hydrogen.
However, the CO2 released during the process can be captured and stored. This is blue hydrogen.
The most sustainable form is green hydrogen. This is produced using sustainably generated electricity, such as wind and sun. In a nutshell, by applying electrical current to water, it is split into hydrogen and oxygen. No CO2 is released during this process.
Launch at the end of 2028
Within the partnership,
Production is expected to start by the end of 2028 or early 2029. The blue hydrogen plant will be connected to both Dutch and German pipelines.
Battolyser
Last year, Eemshaven was already enriched with a hydrogen development: the first Battolyser. This is a combination of an electrolyser (which produces hydrogen) and a battery. A demonstration unit of the Battolyser was placed at RWE's gas-fired Magnum power plant. That is one of the largest power plants in
According to RWE, the hydrogen produced by the Battolyser system would be used to cool the generators in the power plant. RWE wants to test how that works. The intention is for the system to store renewable energy or process it into green hydrogen on an industrial scale.
