Hydrogen production takes system to new levels
Green hydrogen from offshore wind energy at an industrial scale using electrolysis
Putting the brakes on climate change and meeting the challenges of the energy transition is now more urgent than ever. An experienced team of energy experts from Tractebel Engineering GmbH and offshore engineers from Tractebel Overdick GmbH are therefore developing a unique concept for an offshore platform. This makes it possible to produce environmentally friendly “green” hydrogen from offshore wind energy at an industrial scale using electrolysis.
Delivering up to 400 MW, this kind of plant exceeds the output of previous technologies many times over. It could already be put into practice today, for example in the North Sea. The innovative offshore platform can enable a number of tasks to be solved simultaneously. The proportion of “green” hydrogen (H2) in the energy mix can be increased on a CO2-neutral basis. In addition, the wide range of options for transporting H2 provide relief for the electricity transmission grid, the capacities of which are limited. Furthermore, H2 as an efficient energy storage medium can balance out seasonal fluctuations in renewable energy sources.
Enormous potential
The role of Hydrogen (H2) is gaining importance in the energy mix, because it serves as an efficient form of storing energy and is easily transportable. Existing infrastructure can be used for the purpose. H2 is used to power gas turbines and fuel cells, can be used along with natural gas in private households and is also a key industrial raw material. It can be used as a CO2-neutral reducing agent to substitute coke in steel production. In large-scale offshore wind farms Tractebel sees enormous potential for CO2-neutral production of “green” hydrogen.
On the basis of the new type of platform model, the Tractebel team are currently working on a detailed solution for the use of the platform at an industrial scale (400 MW). It accommodates all the technical components required for production – including electrolysis units, transformers and desalinisation plants.
