Decarbonization of the energy sector, requires a strong expansion of renewable energy, which combined with effective and efficient use of resources, enables the development of models based on the green economy. Tidal energy, which is currently underutilized, can contribute to this change by...

The optimal flow allocation in the Zambezi system, the largest multi-reservoir water resources system in southern Africa, is analysed. The problem is formulated in network terms and solved with a network flow algorithm. The present configuration of the system is taken as the reference to...

As devices move from full-scale prototype to commercial installations, it is important that developers have detailed knowledge of the tidal energy resource. Therefore, the spatial distribution of the tidal currents over the northwest European shelf seas has been examined to improve understanding...

Tidal-stream energy devices currently require spring tide velocities (SV) in excess of 2.5 m/s and water depths in the range 25–50 m. The tidal-stream energy resource of the Irish Sea, a key strategic region for development, was analysed using a 3D hydrodynamic model assuming existing, and...

Wave energy conversion (WEC) and Ocean thermal energy conversion (OTEC) are two potentially significant sources of renewable energy that are available to help the Asian Development Bank’s (ADB) developing member countries (DMCs) reduce their dependence on fossil-fuel based energy generation...

Large-scale extraction of power from tidal streams within the Pentland Firth is expected to be underway in the near future. The Inner Sound of Stroma in particular has attracted significant commercial interest. To understand potential environmental impacts of the installation of a tidal turbine...

Hydrodynamic characteristics like lift and drag coefficients of a cascade of blades as well as comprehensive data of pressure loss and flow deflection are important for the design of a hydroturbomachine. In the present paper numerical investigation of flow over a cascade of S-shaped hydrofoils...

As interest in marine renewable energy increases, observations are crucial for understanding the environments that prospective turbines will encounter. Data from an acoustic Doppler velocimeter in Puget Sound, WA are used to perform a detailed characterization of the turbulent flow encountered...

Integrating variable and non-dispatchable renewable power generation into existing power systems will have consequences for their operation and future expansion. These impacts will depend on two factors: (1) the variability of the total renewable power generation on different time scales and (2)...

Tidal hydrokinetic power generation involves the conversion of the kinetic power in swiftly moving tidal currents to renewable electricity. Resource assessment is critical to understand the tidal hydrokinetic potential, but is complicated by a number of factors, including far-field effects....
