- EMEC completes full hybrid test using tidal generation, batteries and hydrogen systems.
- The trial enables stable hydrogen output using a predictable tidal energy cycle.
The tidal-to-hydrogen energy integration trial at EMEC’s site in Eday marks a significant step for clean power innovation. EMEC completed a full demonstration that combined tidal generation, battery storage and hydrogen production in one coordinated system. The achievement strengthens efforts to create reliable renewable solutions. It also demonstrates how the tidal-to-hydrogen energy integration model can support future energy networks.
The project used Orbital Marine Power’s O2 tidal turbine as its primary generation source. EMEC paired this with Invinity Energy Systems’ vanadium flow batteries and an ITM Power 670 kW electrolyser. This combination allowed several operating scenarios that simulated real-world conditions. The team confirmed strong system performance throughout the trial.
Tidal power charged the battery system during strong ebb and flow periods. The battery then supplied energy to the electrolyser when the output from the turbine dropped. This method smoothed the natural cycle of tidal generation. It also enabled the stable production of hydrogen on demand, which supported the project’s primary aim.
The team tested grid export, battery charging and hydrogen generation in different configurations. Each test delivered essential insights into system reliability. The trial also showed how hybrid setups can support continuous operation, even when tidal cycles fluctuate.
EMEC reported that all planned scenarios ran successfully. The additional safety measures performed well during every stage of the demonstration. These results confirm that the hybrid model can operate safely within a commercial environment.
The project formed part of the Interreg North-West Europe-funded ITEG initiative. It also received support from the Scottish Government through Highlands and Islands Enterprise, alongside the EU-funded FORWARD2030 programme. These partnerships strengthened development and ensured long-term knowledge sharing.
Leaders from partner organisations praised the outcome. They highlighted the importance of innovation in expanding renewable energy capacity. Their comments also underlined the value of high-cycling flow batteries and predictable tidal power.
The successful trial provides a clear pathway for future hybrid energy projects. It shows how integrated systems can increase resilience while reducing dependence on fossil fuels. EMEC plans to continue exploring similar solutions to advance energy security.
