2.供应链挑战仍然存在

2.Supply chain challenges persist

英国储能业发展受制于不成熟的供应链以及过度依赖海外生产。大多数英国电池制造商只生产比锂离子电池成本更低的钠离子电池。为了真正从低成本的钠离子电池中获益，英国必须加强制造能力。他们的理由是，这对于英国通过该方式减少碳排放以实现气候目标至关重要。从国内供应商采购电池产品，而不是从中国进口，可以最大限度地减少二氧化碳排放。

The advancement of the UK energy storage industry is being held up by an immature supply chain with an over-reliance on overseas production lines. This means that most UK manufacturers produce sodium-ion cells – which can be produced at a lower cost than, say, lithium-ion batteries – only in low volumes. To truly benefit from the much lower environmental cost of sodium-ion cells, the UK must build out manufacturing capacity onshore. The argument is thatthis is essential to truly fulfil climate goals by reducing the carbon footprint of the industry and that of the UK. Sourcing cell products from domestic suppliers, as opposed to importing from China, minimises CO2 emissions.

3.丞待长时储能发展的政策框架

3.No policy framework for long duration storage

要充分利用储能，包括抽水蓄能，英国政府需要制定长时储能政策框架。长时储能技术理事会强调”政策前景的不确定性”是长时储能商业化发展的主要障碍之一。推动长时储能发展的政策包括：制定容量目标和采购目标，将储能纳入电网规划工作；提高行业收入并提供长期稳定的创收机制，如差价合约、上下限、能源证书、购电协议和基础的资产监管政策；公私合作、补助和激励措施；以及有针对性的招标，以加快早期项目及其所需的基础设施建设。
