Energinet explores electrolyzers as balancing assets in Danish grid

Energinet published analysis on the balancing value of electrolyzers in the Danish zone, framing the question around two competing flexibility mechanisms: linepack flexibility, which uses the gas network as a buffer, and onsite hydrogen storage, which lets the electrolyzer shift its power consumption profile independently of the gas grid.

A companion piece, titled "Electrolysis and hydrogen balancing", sets out the broader case for integrating electrolyzers into balancing markets. The core argument is that electrolyzers are fast-ramping, controllable loads that can respond to real-time grid signals, making them structurally similar to demand-response or BESS assets from the TSO's perspective.

No quantitative results are available from the headlines and summaries alone. The framing, per Energinet, is that the choice between linepack and onsite storage materially changes the economic and operational value an electrolyzer can deliver to the balancing market. Both publications are by Energinet.
