Several companies are developing technologies that aim to generate energy from ocean waves. (Pretty cool looking)

One Response to “Waves and Tides Next Frontier for Energy Exploration”

  1. Starting around the second decade of the twentieth century, developers started assessing the tides for the generation of electricity. Dexter Cooper, an engineer with a summer home in Campobello (New Brunswick), designed a power scheme utilizing the tides of Passamaquoddy Bay and Cobscook Bay. For one mode of development, Cooper proposed an international project capable of continuously generating electricity with a two-pool mode of operation; i.e., using Passamaquoddy as a high pool and Cobscook as a low pool with the installation of power plant and barrages (dams) between the two bays.

    In the 1930s, the United States under President Franklin Roosevelt appropriated funds to construct an “All-American” project based in Cobscook Bay and intrinsically connected to Passamaquoddy Bay. In this case, Cobscook Bay was defined as the high pool and the generation of electricity would have started shortly after high tide once an adequate elevation differential was established between impounded waters in Cobscook Bay and the receding waters of the Bay of Fundy. After two or three years of construction activity, the project was suspended due to concerns associated with economic feasibility and the inability to fully integrate electricity into a regional grid. Other factors included opposition from private utilities for public power and political complications.

    President Kennedy brought back the Cobscook Bay project in the 1960s while combining tidal power with a pumped storage (hydro-electric) project at Dickey-Lincoln (Aroostook County – Maine) for the generation of continuous power. Once again, the scale of the project and concerns associated with public utility integration combined with environmental issues with Dickey-Lincoln resulted in a decision against development.

    During the energy crisis of the 1970s, large scale tidal power for Cobscook Bay and Passamaquoddy Bay was resurrected in terms of an International and all-American project. During this period, the Passamaquoddy Tribe at the Pleasant Point Reservation proposed the construction of the Half-Moon Cove project as both a demonstration project and a decentralized source of energy. Dr. Normand Laberge was hired to develop plans for Half-Moon Cove which eventually led to the filing a license application with the Federal Energy Regulatory Commission (FERC). The project was deemed technically feasible but marginally viable on economic grounds due to the fee structure established in Maine for renewable energy projects during the early 1980s….
