Energy from tidal currents (innovation fund)

New Zealand has large, untapped sources of renewable marine energy

New Zealand has large untapped sources of renewable ocean energy. Tidal currents are a highly predicable renewable energy source, and Raukawa Moana/Cook Strait is arguably the best site in the world for generating power from tidal currents.

Kick-starting a new marine industry with huge potential

This project is developing the tools and methods needed to estimate the scale of investment required for wide-ranging scenarios of tidal farm sizes and locations.

Energy is the critical mainstay of our daily lives, from growing and transporting food to manufacturing and powering the vast array of technological innovations we depend on. New Zealand faces the conflicting imperatives of expanding our energy supply for a growing economy, while rapidly transitioning to green energy sources in order to mitigate the worst impacts of climate change. New Zealand’s renewable electricity generation must almost double by 2050, if we are to achieve a 100% renewable generation target. We are fortunate in having large untapped sources of renewable energy in the oceans surrounding us.

A critical first step to unlocking this huge potential is estimating the scale of investment required to meet current needs. New tools and methods are needed to address the huge computational requirements to make these estimates for different tidal farm scenarios.

Sustainable Seas features on Ocean Bounty S2 EP7

Sir Rob Fenwick,  our Chairman was interviewed about Sustainable Seas on S2 EP7 of Ocean Bounty. You can watch it here on TV 3 on demand.  (6.57 to 11.20).  

Consultation opens re 2019–2024 strategy

Improving marine management is critical to New Zealand's future health and wealth, but research in isolation is not enough. Excellent engagement with, and participation from, all users and sectors of society is essential.

We therefore invite comment on our draft strategy for Phase II (2019–2024). This strategy has been co-developed with Māori and stakeholders.

Sun, sea, sand – and marine science

During Seaweek, more than 4,600 school pupils joined 6 Sustainable Seas researchers for 3 days of marine science fieldwork in Tasman Bay, as part of the LEARNZ virtual field trip Sustainable seas – essential for New Zealand’s health and wealth.
