The Tidal In-Stream Energy (TISE) industry is growing at a relatively fast pace. Crucial and augmentative to TISE’s development is the existence of an appropriate ecosystem of methodologies, tools, and protocols for assessment and planning of resources, technology / devices, environment, economics, installations, social impact, and policy. Current TISE evaluation rarely combine site suitability, resource assessment, and technology / device matching; and hardly can any of these tools be described as rapid, labelled as integrated nor deemed as flexible.
This work develops, studies, and proposes: (1) a simpler TISE metric for resource estimation, (2) a novel Tidal Resource Investigation, Device and Energy Tool (TRIDEnT), and (3) a method for assessing multiple sites and multiple devices using adapted power development planning criteria. Validation and benchmarking of the proposed metric and developed tool against in-situ measurement and selected methods / tools (EPRI, STEM, ESRU, GeorgiaTech) for resource assessment are done. Energy density maps are generated via TRIDEnT and are presented for four sites in the Philippines, namely: Matnog-San Bernardino Strait, Verde Island Passage, Cebu-Santander Strait, and Davao Samal-Talicud Channel.
Case studies for TRIDEnT featuring its key capabilities, such as resource analysis, device performance assessment, site-device suitability scoring scheme for 4 sites and 8 TISE conversion (TISEC) devices, and decision support mechanism (using depth constraints, and factoring in of power demand), are demonstrated. The TISE potential of selected sites in the Philippines is quantified for the first time. Selected TISEC devices are nominated, matched, and ranked (in order of suitability) as candidate tidal power plant installations: RTT2000, HS1000, Open-Center for Matnog-San Bernardino Strait, RTT2000, Open-Center, GCK Gorlov Verde Island Passage, and RTT2000, Gen5, HS1000 for Davao Samal-Talicud Channel.
Five key contributions for the field of TISE evaluation are presented in this work, namely: (1) a macro-level resource assessment using an energy potential metric based on tide-height differences at the boundaries of a channel of interest; a MatlabTM-based integrated, rapid evaluation tool (2) with multiple site resource analysis (equipped with velocity histograms, frequency-intensity-direction diagrams, time- series plots, and energy density maps) capability, (3) multiple device (featuring a flexible database with parameters of interest) performance assessment capability, (4) a combined multi-site, multi-device suitability scoring scheme, and (5) a decision support system for use in pre-development / feasibility studies.
