(Reuters) - Germany has looked to liquefied natural gas (LNG) imports to replace piped Russian gas since Moscow's invasion of Ukraine in 2022.

Its first move has been to deploy floating storage regasification units (FSRUs) to receive seaborne LNG, while longer term it plans shore-based regasification terminals and facilities to import and produce ammonia and green hydrogen.

Below are details of the latest developments:

MUKRAN

The terminal on Ruegen island in the Baltic Sea supplies onshore grids with LNG via pipeline firm Gascade's new OAL pipeline.

On April 4, private operator Deutsche ReGas launched a three-month bidding round for expanding Mukran's long-term regasification capacity by offering an additional 5 bcm per year from 2027 to 2043.

Currently, ReGas only employs Norwegian operator Hoegh's FSRU Neptune at Mukran, after ReGas cancelled a second FSRU, the Energos Power, in February, due to low utilisation.

ReGas has said it struggles to compete with fees offered by state-owned Deutsche Energy Terminal GmbH (DET) to attract cargoes at DET-supervised, more western lying, North Sea terminals while German LNG business is generally slow.

But it also said it was sticking to plans for restarting a second FSRU and restoring Mukran's full capacity of 13.5 bcm annually by 2027.

LUBMIN

ReGas and Hoegh in June 2024 signed an agreement to develop the Baltic Sea port, a forerunner of Mukran, into an ammonia/hydrogen import terminal.

STADE

Hanseatic Energy Hub (HEH) in 2024 took a final investment decision for a land-based, ammonia-ready terminal at the Elbe river inland port to start in 2027.

The terminal is expected to cost around 1 billion euros ($1.09 billion).

Employment of the FSRU Energos Force that was expected to run until 2027, ahead of the onshore terminal starting operations, is delayed until further notice after DET and HEH cancelled contracts with each other over unresolved disputes about construction schedules and payments.

WILHELMSHAVEN

Utility Uniper launched Germany's first FSRU operation, Wilhelmshaven 1, on the North Sea, in 2022.

Uniper plans to add a land-based ammonia import reception terminal and cracker in the second half of this decade to make green hydrogen, and build a 200 MW electrolyser to be fed with local wind power.

DET said there are plans for a second FSRU at Wilhelmshaven but has not specified a commissioning date.

BRUNSBUETTEL

The Brunsbuettel FSRU went into operation in 2023 on the North Sea coast, initially chartered and operated by utility RWE's trading arm before it was handed over to DET.

It is the forerunner of a land-based LNG facility which has been cleared to receive 40 million euros of state support.

It could start operations at the end of 2026, when a newly inaugurated, adjacent ammonia terminal could also start up.
