Groningen Gas Field: TNO Calls for Strategic Reserve Amidst Import Risks

The debate surrounding the complete closure of the Groningen gas field has intensified, with the Dutch research institute TNO advocating for its retention as a strategic reserve. This recommendation comes as the Netherlands increasingly relies on imported gas, facing growing geopolitical uncertainties that threaten supply security. While not proposing a return to commercial gas production, TNO argues that maintaining a reserve within the Groningen field is crucial to mitigate potential shortages.

Growing Reliance on Gas Imports

Currently, approximately 80 percent of the Netherlands’ natural gas supply is imported according to NOS. This dependence exposes the country to vulnerabilities stemming from global events and political influences. Large pipelines from Norway are susceptible to sabotage, as demonstrated by the Nord Stream incidents, while Liquefied Natural Gas (LNG) supplies from the US and the Middle East are subject to political pressures and potential disruptions, such as closures of key shipping routes like the Strait of Hormuz.

TNO’s Proposal: A Strategic Reserve

René Peters, director of gas technology at TNO, emphasizes the need for a non-depleted emergency gas supply. He suggests that the Groningen field, which still holds an estimated 550 billion cubic meters of gas as reported by NL Times, is a suitable candidate for this purpose. This reserve would be similar to the strategic oil reserves the Netherlands has maintained since the 1970s – available for use only in crisis situations.

Peters clarifies that his proposal is not about resuming regular gas production. He envisions the reserve as a “last resort” measure, to be utilized only when other supply sources are compromised. He highlights that existing underground storage facilities, such as Norg and Grijpskerk, are routinely emptied during winter and do not provide a true strategic reserve.

Political Opposition and Concerns

Despite TNO’s warnings, the proposal has faced resistance from political parties, including those within the governing coalition as reported by Dagblad van het Noorden. Some right-wing parties have even used the argument to advocate for continued regular gas extraction, a position Peters explicitly rejects.

Ongoing Field Closure

Currently, the NAM is actively dismantling and sealing gas wells in Groningen. As of February 2026, 70 of approximately 300 wells have been sealed, and 22 locations have had six dismantled according to NL Times. The debate continues as to whether this process should be completed entirely, or if a portion of the field should be preserved as a strategic safeguard against future energy disruptions.

Key Takeaways

• The Netherlands is increasingly reliant on imported gas, making it vulnerable to supply disruptions.
• TNO proposes retaining a portion of the Groningen gas field as a strategic reserve for emergency situations.
• The proposal is not for resuming commercial gas production, but for maintaining a safeguard against geopolitical risks.
• Political opposition remains strong, with many advocating for complete field closure.
