NY Roosevelt Island Tidal Energy Project Progressing (Ind. Report)
Verdant Power
Date: 2021-01-05
As previously reported, NYC-based marine renewable energy start-up Verdant Power has installed three tidal power turbine generators at its Roosevelt Island Tidal Energy (RITE) project in the city’s East River tidal strait as part of the company’s 5th generation tidal turbine system. The deployment of Verdant’s technology also marked the first licensed tidal power project in the US.

The RITE project received $6m in US DOE funding and support from New York State Energy Research and Development Authority (NYSERDA), in addition to New York-based private equity capital support. The company is also waiting for an independent performance assessment from the European Marine Energy Centre (EMEC) tidal testing facility to deploy the technology outside of the US.

According to Verdant Power co-founder and chief marketing officer Trey Taylor: “Given the East River’s depth and tidal current speed of 2.25m/s, the company’s fifth-generation system or ‘commercial standard system’ has been tailored to this site by using five-metre diameter rotors with 35kW nameplate generators -- three to a single TriFrame or 105kW. Since installation on 22 October, the TriFrame has generated an average 1MWh per day or enough power for 500 Manhattan apartments.” (Source: Verdant Power, Website, PowerTechnology, 4 Dec., 2020) Contact: Verdant Power, Trey Taylor, CMO, www.linkedin.com/company/verdant-power

$38Mn Funding for Hydrokinetic Turbine Tech. Development (Funding)
US DOE
Date: 2020-04-13
The U.S. DOE is reporting the availability of up to $38 million in funding through its Submarine Hydrokinetic And Riverine Kilo-megawatt Systems (SHARKS) program for the design of economically attractive hydrokinetic turbines for tidal and riverine currents.

The turbine devices can be designed with low visual profiles and minimal environmental impact. They are also uniquely suited for micro-grid applications, supplying energy to remote communities and other "blue economy" and utility-scale applications. Hydrokinetic energy can also be used for climatological observation, aquaculture, desalination, ocean floor and seawater mining, disaster recovery, powering isolated communities and autonomous underwater vehicle support.

Currently, significant technical and environmental barriers make current hydrokinetic turbine systems prohibitively expensive. SHARKS will fund the development of solutions for hydrodynamics, mechanical structures, materials, hydro-structural interactions, electrical energy conversion systems, control systems, numerical simulations and experimental validations.

SHARKS projects will work towards a reduction in Levelized Cost of Energy (LCOE) of up to 61.5 pct compared to current state-of-the-art hydrokinetic turbine systems. (Source: US DOE, April, 2020) Contact: SHARKS, arpa-e-foa.energy.gov › FileContent PDF

Cross-Flow Tidal Power Turbines Tested at U. Washington (Ind. Report)
University of Washington
Date: 2019-08-19
In Seattle, Engineers at the University of Washington Applied Physics Lab report they are testing the performance of "cross-flow" turbines on Lake Washington with the view of developing reliable tidal power.

In early early testing, the team is driving a test boat with a pilot model cross-flow turbine at variable speeds and monitoring the turbine's energy output.

The cross-flow turbine blades are a simpler shape than those used for axial turbines, which generate energy from the drag that wind or water flow puts on their blades. Cross-flow turbines generate energy from a "lift" effect similar to airplane wings. And, unlike axial turbines, cross-flow turbines do not need to adjust the position of the blades or the direction the turbine faces, but they do need to regulate the speed to get the maximum energy output.

Orbital Marine Power Demo Set for Morlais Tidal Energy (Int'l)
Orbital Marine Power
Date: 2018-12-07
In Scotland, Orbital Marine Power -- fka Scotrenewables Tidal Power -- is reporting an agreement to demonstrate its recently unveiled "O2" 2MW tidal turbine technology at the Morlais Tidal Energy Project in Anglesey. Orkney-based Orbital claims its "O2" 2MW tidal turbinewill be the most powerful tidal generating platform in the world - with each 2 MW unit capable of producing electricity equivalent to the demands of 1,500 typical UK homes.

Orbital has also launched a £7 million crowdfunding effort.

Tidal Turbine Specialist Generates Private Investment (Int'l)
Scotrenewables
Date: 2018-09-28
Orkney Islands-based floating tidal turbine developer Scotrenewables Tidal Power Ltd reports it has secured a multi-million pound investment from the McGrath family and Matthias Haag -- the former CEO of the company behind the 600-MW Gemini offshore wind park. Scotrenewables also received support from the Scottish government's Energy Investment Fund.

Scotrenewables is preparing for a 2019 construct and installation of its SR2-2000 tidal power turbine. (Source: Scotrenewables Tidal Power Ltd., Renewables, 26 Sept., 2018) Contact: Scotrenewables Tidal Power Ltd., office@scotrenewables.com Telephone: 01856 851641 www.scotrenewables.com
