Britain's Energy Cyber Plan Meets a China Supply Chain It Cannot Quickly Replace

Britain's Energy Cyber Plan Meets a China Supply Chain It Cannot Quickly Replace A security think tank says the UK's new energy cyber strategy has merit, but unwinding dependence on Chinese clean-energy hardware will be slow and expensive. A security and defence think tank delivered a measured verdict on Britain's new energy cyber security strategy on Tuesday (2026-06-02). The plan has value as an action plan, its analysts told Montel, but fully diversifying away from China will be "a difficult process."⁶ That matters because the hardware Britain is installing to decarbonise, from solar modules to batteries to grid components, sits on supply chains that China dominates from the mine to the finished cell. A cyber strategy governs who can reach into the system. It does little about who built the kit in the first place.⁶ The numbers behind that dependence are stark. China refines 60% of the world's lithium and 80% of its cobalt, the two core inputs for high-capacity electric batteries, according to Economist figures published on 2026-05-19.³ Europe imports 98% of its rare earths from China, more even than the United States at 80%.³ These are not commodities a country re-sources within a budget cycle. The warning is the second in a series. In late May (2026-05-21) the same line of analysis framed China as a direct security threat to the UK energy system, arguing that Britain would need a coordinated response with allies rather than a national fix.¹ The analyst told Montel the biggest challenge lay in the scale of the exposure itself.¹ Europe has walked into a version of this before. A Dutch-based think tank argued on Monday (2026-05-18) that the continent's move away from Russian energy removed one major vulnerability while risking another, as growing reliance on US LNG opens it to fresh economic shocks.² The lesson for London is uncomfortable. Swapping one concentrated dependence for another is not the same as removing it. The EU has at least put a figure on its ambition. Its Critical Raw Materials Act sets a target that no more than 65% of annual consumption of any listed material should come from a single country by 2030.³ That still tolerates heavy concentration, and the trend has run the wrong way: the share of German subsidiaries' activity tied to China rose from 2% in 2002 to 52% in 2012 and a record 85% in 2022.³ Why the grip is so hard to break comes down to where China sits in the energy transition. Electricity now accounts for roughly 30% of China's final energy consumption, above the level in Europe or the United States, according to analysis published on 2026-05-19.⁴ That lead in clean-energy manufacturing is backed by state guidance funds taking equity stakes, cheap loans from state banks, and local governments competing to subsidise firms.⁵ The more the world electrifies, the more it leans on Chinese equipment. For the UK, that leaves the cyber strategy doing useful but narrow work. It can harden control systems and vet who connects to the grid. It cannot manufacture a domestic battery supply chain or conjure rare-earth refining capacity that does not yet exist outside China.^6,3 The real trade-off is between speed and security. Diversify slowly and the exposure persists for years. Diversify fast and the cost lands on energy bills and project timelines, exactly when Britain is trying to accelerate renewables rather than stall them.⁶ What to watch is whether the strategy arrives with procurement rules that bite: sourcing thresholds, allied supply agreements, or stockpiles of critical inputs. The EU's 65% benchmark and its 2030 deadline are the nearest reference point on offer.³ Without something equivalent, a cyber action plan risks bolting the front door of a house whose foundations were poured in China.⁶
