Globally, marine energy feasibility studies and equipment development continue

Indonesia – MoU for Phase II tidal array development
SBS Intl. Ltd. announced it has signed a memorandum of understanding with PT. Indonesia Power to conduct a feasibility study to expand the 12 MW Phase I, currently being constructed, of the planned 150-MW tidal array project at the island of Lombok in Indonesia.

Phase 1 uses eight 1.5-MW Nautilus tidal turbines and is scheduled for completion in 2020. The MoU signed on Jan. 16 begins discussions to study the Phase II expansion, which developers say could be up to 70 MW.

SBS said the tidal project will need an experienced electrical transmission contractor for power transmission extension works on Lombok to receive ocean energy power from the tidal-stream turbines when installed.

In October 2017, Indonesia’s first ocean energy independent power producer, SBS Energi Kelautan, announced it completed final investment decision with SBS to move forward with Phase I. Energy generated by the project will be sold to state-owned utility Perusahaan Listrik Negara through a 25-year power purchase agreement.

In April 2016, HydroWorld.com reported marine energy developer Atlantis Resources Ltd. signed a memorandum of understanding with SBS Intl Ltd. to establish the tidal stream array project.

Per the initial agreement, the project would be constructed in stages, with an estimated cost of US$750 million.

Canada – Schottel Hydro and subsidiaries revise business plans
Germany-based Schottel Hydro and its wholly-owned subsidiaries TidalStream Ltd. (TSL) and Black Rock Tidal Power (BRTP) have revised their business strategy.

The group says it is moving away from large arrays, similar to BRTP’s Triton platform, towards smaller units, according to Schottel Hydro.

BRTP is developing and installing the Triton S40 at FORCE, according to the Fundy Ocean Research Center for Energy (FORCE), located in the Bay of Fundy, Nova Scotia, Canada. The Triton S40 supports 40 lightweight-horizontal axis Schottel instream turbines and related electrical power conversion equipment for the autonomous production of 2.5 MW of electrical power in high tidal flow velocities.

Following the company’s comprehensive review, BRTP will initially plan to use smaller floating platforms, such as the Sustainable Marine Energy Ltd. PLAT-I platform, for its FORCE project.

“Schottel Hydro and its subsidiaries remain convinced about the positive future of the tidal energy sector in Nova Scotia, and around the world,” said Niels A. Lange, managing director of Schottel Hydro, the tidal power division of Schottel Group.

“We remain committed to tidal energy power generation and firmly believe in its viability. We will initially focus on modular, scalable floating platforms,” Lange said. “Schottel Hydro will also continue to provide services as a tidal turbine and power take-off systems expert.”

Lange also said Schottel Hydro is excited by opportunities in Nova Scotia and Southeast Asia and sees a strong development opportunity working with other platform partners.

Northern Ireland – Funding supports new marine energy research center
About US$11.46 million in funding and support has helped launch the Bryden Centre for Advanced Marine and Bio-Energy Research (Bryden Centre), in Northern Ireland.

The funding is from the European Union, the Department of Business, Enterprise and Innovation in Ireland, and the Department for the Economy in Northern Ireland.

Located at Queen’s University in Belfast, in partnership with the University of the Highlands and Islands, Bryden Centre will recruit 34 PhD students working in a range of marine and bio-energy disciplines and focus on technologies such as tidal power.

This will involve staff completing research at ocean energy sites in Western Scotland, Ireland and in Northern Ireland.

Partners include Letterkenny Institute of Technology, Ulster University, Donegal County Council, and Dumfries and Galloway Council.
