In early July 2026, Croatia completed an 11 MW solar farm at the INA refinery in Rijeka, a key component of the country’s first commercial green‑hydrogen plant slated to deliver renewable hydrogen from 2027. Around the same time, Hungary launched a public‑charging incentive programme, offering up to €3.6 million to partners that install high‑power DC EV chargers and share revenue for ten years.

By late July, the momentum in Hungary intensified when Greek‑based DEI Group, through its DEI Renewables subsidiary, formalised the acquisition of a 57.5 MW photovoltaic park in Királyegyháza, southern Hungary, and secured rights to a neighbouring 49 MW battery‑energy‑storage system capable of four‑hour discharge. The solar plant, already in commercial operation since July 2024 under a 25‑year state‑backed fixed‑price contract, marks DEI’s first entry into Hungary’s rapidly growing clean‑energy market and is part of a €24 billion 2026‑2030 strategy to double its capacity and create a regional renewable‑energy platform linking Greece with Central and South‑Eastern Europe.

Together, these developments illustrate a rapid scaling of renewable infrastructure in the region—from solar‑enabled hydrogen production and EV‑charging incentives to large‑scale solar generation and integrated storage—highlighting expanding corporate investment and policy support for a low‑carbon energy transition in Central Europe.
