National Grid Ventures (NGV), the arm of National Grid that develops and operates LionLink, has completed a fresh series of primary school activities across Suffolk as an extension of British Science Week.

Designed specifically for LionLink, the first hybrid electricity interconnector between Great Britain and the Netherlands, the sessions helped pupils aged four to eleven understand how the project works beneath the surface, while building broader awareness of renewable energy across the region.

This is the second year the LionLink team has visited schools in Kelsale, Southwold and Snape, with Yoxford joining for the first time. In total, 355 pupils took part in an age‑appropriate energy journey explaining how offshore renewable power is generated, transported safely between countries, and delivered to homes across Great Britain.

Through hands‑on demonstrations, children explored wind energy using airflow experiments that showed how offshore turbines generate power; energy control and grid stability through a visual balancing activity linked to LionLink's converter stations and High Voltage Direct Current (HVDC) systems; solar energy and the connection between sunlight, wind and the wider renewable‑energy system, reinforced with flash‑paper experiments; and subsea interconnection, described as an 'invisible river of energy' travelling beneath the North Sea to support up to 2.5 million homes.

A whole‑school rainbow‑light activity saw every child use diffraction glasses to reveal the hidden colours within white light—a metaphor for understanding unseen energy through science and engineering.

The 40‑minute interactive STEM show, themed Currents Unseen, was delivered in partnership with Mad Science. Presenters Dr Dee Enay (Laura Bird) and Prehistoric Paul—known for a dynamic, theatrical approach to science education—used immersive demonstrations, visual experiments and humour‑driven teaching to explain the invisible forces behind renewable energy and subsea electricity transmission.

Members of the LionLink project team attended to support Mad Science and answer pupils' questions about clean energy and the future of electricity.
