Hydrogen as a solution to ease power grid congestion
July 9, 2020
A study by DNV GL in partnership with Enexis, Gasunie and the NAM demonstrates that local hydrogen production through electrolysis near wind and solar farms is a promising solution to ease the problems arising from the current situation related to the power grid congestion.
The study focused on Emmen, The Netherlands as a case study as this area faces significant problems with power grid congestion.
The study further underlines that local hydrogen production can ease congestion in the electricity grid, mainly because electrolysers can be located strategically and close to the power source such as solar and windfarms. including that hydrogen can be transported instead of electricity. Importantly, using hydrogen as a form of storage could help improve utilisation of existing network assets and manage network congestion. This could reduce the need for ‘over-build’ of generation while also enabling larger renewable energy projects than the electricity system could otherwise support by providing an off-take for the excess electricity.
Moreover, the locally produced hydrogen can be transported through already existing gas infrastructure and supply local industry. Namely, already existing gas pipelines, such as those of the NAM and Gasunie have sufficient capacity and can be rebuilt to supply large quantities of hydrogen. The existing gas pipelines can also offer possibilities for the storage of hydrogen. This increases the flexibility of the electricity network.
