Comparative Life Cycle Assessment of tidal stream turbine blades

International Marine Energy Journal, 2022
Renewable energy allows electricity generation with lower environmental and resource impact than generation from fossil fuels. However, the manufacture, use and ultimate disposal of the equipment used to capture this energy has an environmental impact, which should be minimised. Tidal turbine blades are currently primarily manufactured from glass-fibre

Water‐Borne Erosion of Reinforced Polymer Composites: Application to Shallow Offshore Marine Environment

Polymer Composites, Volume 47, Issue 5, Page 4102-4126, 10 March 2026.
Comparison of experimental and model‐predicted erosion rates for carbon fibre‐reinforced polymer (CFRP) and glass fibre‐reinforced polymer (GFRP) under low‐velocity (2 m/s) and at varying angles and sand concentrations (0.0, 0.05, 0.4 g/L). The results demonstrate good agreement between experimental data and model predictions across different erosive ...

Experimental Analysis and Evaluation of the Numerical Prediction of Wake Characteristics of Tidal Stream Turbine

Energies, 2017
It is important to understand tidal stream turbine performance and flow field, if tidal energy is to advance. The operating condition of a tidal stream turbine with a supporting structure has a significant impact on its performance and wake recovery. The

CFD Simulations of the Effects of Wave and Current on Power Performance of a Horizontal Axis Tidal Stream Turbine

Journal of Marine Science and Engineering, 2023
To ensure the long-term reliability of tidal stream turbines, waves and currents must be considered during the design phase. In this paper, a three-bladed horizontal axis turbine with a diameter of 0.9 m was used as the baseline model.

A Conceptual Framework and Methods for Studying the Connectivity of Fishes

Fish and Fisheries, Volume 27, Issue 2, Page 342-369, March 2026.
ABSTRACT Connectivity is a multifaceted concept that has important implications for the management and conservation of marine and freshwater fishes. We developed a conceptual framework that encompasses multiple, interrelated categories of connectedness, including landscape (e.g., structural, functional) connectivity and ecological (e.g., trophic ...

Shrouded Wind and Water Turbine Analytical Model Extensions for Tip Gaps, Center Bodies, and Flow Blockage

Wind Energy, Volume 29, Issue 2, February 2026.
ABSTRACT This paper provides improvements to a previously presented simple, accurate, lower order analytical model for predicting the performance of horizontal‐axis shrouded turbines for a wide range of shroud airfoil shapes varying in length, camber, and thickness. The new, extended model incorporates explicit quantitative predictions of those effects

Impacts of the renewable energy transition on global plant diversity: A review

PLANTS, PEOPLE, PLANET, Volume 8, Issue 1, Page 87-115, January 2026.
People and nature need a renewable energy transition to help address the growing, and catastrophic, effects of climate change. A sustainable energy transition involves rigorously examining the potential impacts on nature – including plant life – and creating pathways for impact mitigation that strike a clear balance between energy production and ...
