Daikin to supply Hitachi Energy with C4-FN, supporting the rapid expansion of Hitachi Energy's EconiQ^® portfolio of SF₆-free grid technologies

• Hitachi Energy and Daikin Industries, Ltd. sign MoU for the supply of C4-FN, a specialty gas component in Hitachi Energy's SF₆-free switchgear, from its Frankfurt facility starting in 2027 
• Partnership strengthens a multi-region supply chain and secures long-term availability of a critical technology
• New production capacity supports the manufacturing of clean energy technologies in Europe

ZURICH, Sept. 3, 2026 /PRNewswire/ -- Hitachi Energy and Daikin Industries, Ltd. today announced an agreement to establish a long-term strategic supply relationship for Hitachi Energy's EconiQ^® portfolio of sulfur hexafluoride (SF₆)-free high-voltage technologies. As part of the agreement, Daikin Chemical Europe GmbH, a subsidiary of Daikin Industries, Ltd., will supply C4-FN, a specialty gas component used in insulating gas mixtures. The C4-FN will be produced by Daikin Refrigerants Frankfurt GmbH at its facility in Frankfurt, Germany, leveraging advanced manufacturing capabilities, high quality, and environmental standards. The new production capacity will become available in 2027 and is part of a resilient global supply strategy for critical materials used in Hitachi Energy's SF₆-free EconiQ technology.

SF₆, a strong greenhouse gas with a global warming potential 24,300 times greater than CO₂, is commonly used in high-voltage equipment for its superior insulation and switching properties. Utilizing C4-FN gas, the EconiQ portfolio reduces CO₂-equivalent emissions by 99 percent compared with conventional SF₆-insulated equipment, while retaining the same technical performance, reliability, and compactness.

The announcement comes as demand for EconiQ continues to grow worldwide. The portfolio has attracted more than 4,000 orders across 40 countries, as utilities and industries expand and modernize their power grids while eager to reduce the environmental impact of their infrastructure.

To support this growth, Hitachi Energy is pursuing a multi-sourcing strategy for key materials. The addition of Daikin as a supplier strengthens the supply chain behind the EconiQ portfolio, complementing existing qualified sources in Asia with capacity in Europe.

"As the demand for eco-efficient equipment continues to grow around the world, strengthening our supply chain is essential," said Markus Heimbach, CEO, High Voltage Products Business Unit, Hitachi Energy. "Adding a world-classproduction site in Germany enhances supply resilience and supports the manufacturing of clean energy technologies in Europe. We want to be sure that we can continue meeting customer demand."

"This agreement reflects a shared commitment to supporting the energy transition through innovation, quality, and long-term collaboration," said Yasuhisa Hirao, General Manager, Chemicals Division, Daikin Industries, Ltd. "We are proud that our group company, Daikin Refrigerants Frankfurt GmbH, will produce an essential component of the global value chain for power grids."

Daikin brings nearly a century of experience in chemical manufacturing, a global network spanning Asia, North America, and Europe, and long-standing sustainability commitments under its Environmental Vision 2050, including targets for greenhouse gas emissions reduction certified by the Science Based Targets initiative.

Im Magdeburger Landtag steht ein Einschnitt in der bundesdeutschen Parlamentsgeschichte bevor: Erstmals könnte ein Abgeordneter der AfD das Amt des Landtagspräsidenten übernehmen. Der 35-jährige Tobias Rausch, seit 2016 Mitglied des Landtags von Sachsen-Anhalt und Generalsekretär der AfD im Bundesland, geht mit einer komfortablen Mehrheit in die konstituierende Sitzung. Nach ihrem klaren Wahlsieg stellt die AfD künftig 39 der 83 Abgeordneten und ist damit die mit Abstand stärkste Fraktion.

Den entscheidenden Schub liefert das Bündnis mit dem Bündnis Sahra Wagenknecht (BSW). Die fünf BSW-Abgeordneten wollen geschlossen für Rausch stimmen und kommen gemeinsam mit der AfD auf 44 Stimmen. BSW-Fraktionschef Thomas Schulze verweist auf parlamentarische Gepflogenheiten: Als stärkste Fraktion habe die AfD laut Geschäftsordnung Anspruch auf den Vorsitz im Parlament. Eine politische Blockbildung gegen die AfD lehnt Schulze ab und präsentiert die Zustimmung zur Wahl des Landtagspräsidenten als Signal eines „neuen Politikstils“.

Die übrigen Fraktionen reagieren gespalten. CDU, SPD, Grüne und Linke verfügen zusammen ebenfalls über 39 Mandate, treten aber nicht geschlossen gegen die AfD an. Die CDU hat angekündigt, sich bei der Wahl zu enthalten – Enthaltungen zählen in diesem Verfahren nicht als abgegebene Stimmen. SPD, Grüne und Linke wollen gegen Rausch stimmen. Spannend bleibt damit vor allem die Frage, ob der AfD-Kandidat über die absehbaren 44 Ja-Stimmen hinaus zusätzliche Unterstützung erhält. Vor der geheimen Abstimmung spekulieren die Lager bereits über mögliche Abweichler; aus der AfD-Spitze heißt es, zusätzliche Stimmen könnten auch aus dem Kreis der erklärten Gegner stammen.

Parallel zur Präsidentenwahl testet die AfD aus, wie weit ihr neuer Einfluss im Landtag reicht. Die Fraktion will die Geschäftsordnung ändern, um neben dem Präsidenten auch einen der drei Vizepräsidentenposten zu besetzen – vorgesehen ist der Abgeordnete Hans-Thomas Tillschneider. In der Vergangenheit sorgten seine Beiträge zur Bildungs- und Kulturpolitik regelmäßig für Kritik in anderen Fraktionen, die den Personalvorschlag daher als Provokation werten dürften. Ob das BSW diese Personalie ebenso mitträgt wie die Wahl von Rausch, ist bislang offen. Unabhängig vom Ausgang der Abstimmungen wird die erste Sitzung des neu gewählten Landtags damit zum Testfall für künftige Zusammenarbeit und Machtarithmetik in Sachsen-Anhalt.
