Commission releases 8th nuclear illustrative programme under Euratom Treaty

The European Commission has published its eighth Programme Illustrative Nucleaire (PINC) under Article 40 of the Euratom Treaty, assessing €241bn in nuclear investment needs through 2050. The programme outlines regulatory priorities including enhanced nuclear safety standards, waste management protocols, and measures to accelerate licensing through regulatory cooperation. The Commission will finalise the PINC following an Opinion from the European Economic and Social Committee (EESC), with discussion scheduled at the Energy Council on 16 June 2025 in Luxembourg. The assessment aligns with EU decarbonisation targets, the REPowerEU Plan and Clean Industrial Deal objectives.

DESNZ announces £500m investment to develop UK’s first regional hydrogen transport and storage ...

The Department for Energy Security and Net Zero (DESNZ) has announced a £500m investment to develop the UK’s first regional hydrogen transport and storage network. The network will connect hydrogen producers with end users—such as power stations and industrial facilities—in regions such as Merseyside, Teesside and the Humber. It will further advance low carbon hydrogen production through continued Hydrogen Allocation Rounds (HAR), building on the £2bn in government funding previously awarded to 11 projects under HAR1.

DESNZ announces £9.4bn funding package for carbon capture and storage projects

The Department for Energy Security and Net Zero (DESNZ) has announced £9.4bn in funding to support a range of carbon capture and storage (CCS) projects as part of the government’s 2025 Spending Review, including the Acorn project in Aberdeenshire and the Viking project in the Humber. This includes £200m in initial development funding for the Acorn project, subject to business case approval. At peak construction, the Acorn and Viking projects are anticipated to support approximately 15,000 and 20,000 jobs respectively, with both projects targeting financial closure later in this Parliament, subject to project readiness and affordability. Once operational, they are expected to collectively remove up to 18 million tonnes of CO₂ annually. The funding will also support the National Gas SCO₂T Connect project, which involves repurposing an existing 175-mile gas pipeline and constructing an additional 35 miles of new build pipeline, to transport CO₂ captured at Grangemouth to storage facilities under the North Sea.

UKIFS announces £2.5bn funding commitment for world’s first prototype fusion power plant

UK Industrial Fusion Solutions (UKIFS) has announced an additional £2.5bn in funding for the Spherical Tokamak for Energy Production (STEP) programme, aimed at developing the world’s first prototype fusion power plant. The facility will be constructed at the site of the former West Burton A coal-fired power station near Retford and Gainsborough, and is expected to be operational by 2040. STEP operates by fusing the hydrogen gases—deuterium and tritium—which are heated to over 150 million ˚C and confined within a magnetic field. The resulting energy will be used to produce steam, which will turn a turbine to generate electricity.
