Asset Redeployability and Biodiversity Risk

Business Strategy and the Environment, EarlyView.
ABSTRACT We examine how asset redeployability influences a firm's exposure to biodiversity risk. Our empirical analysis provides robust evidence that firms possessing greater levels of redeployable assets exhibit significantly lower biodiversity risk.

Prospective LCA of E‐Methanol Along the Transformation of Steel Industry

Chemie Ingenieur Technik, EarlyView.
The environmental effects of change in steel production route on e‐methanol production are analyzed as they shift from blast furnace route to direct reduction route. Specific hydrogen demand reduces, as do the avoided CO2 emissions. E‐methanol's overall carbon footprint stays in a narrow range of −1 to −1.1 kg‐CO2‐eq./kg‐methanol.

Study on Dynamic Response of Offshore Wind Turbine Structure Under Typhoon

Polish Maritime Research, 2022
Floating offshore wind turbines are easily affected by typhoons in the deep sea, which may cause serious damage to their structure. Therefore, it is necessary to study further the dynamic response of wind turbine structures under typhoons.

Accessing offshore wind turbines for maintenance : calculating access probabilities, expected delays and the associated costs using a probabilistic approach [PDF]

, 2012
There are ambitious plans in place for the expansion of offshore wind-power capacity in the EU and elsewhere. However, the cost of energy from offshore wind is much higher than that from land-based generation and anything between 15% and 30% of this cost

Structured Replacement Policies for Offshore Wind Turbines

Probability in the Engineering and Informational Sciences, 2023
AbstractWe consider the problem of optimally maintaining an offshore wind farm in which major components progressively degrade over time due to normal usage and exposure to a randomly varying environment. The turbines exhibit both economic and stochastic dependence due to shared maintenance setup costs and their common environment.

Hybrid Simulation–Machine Learning Surrogates for Coordinate‐Based Solar and Wind Energy Yield Assessment in Iraq: A Streamlit Decision‐Support Tool

Energy Science &Engineering, EarlyView.
This study integrates climatic simulations with machine learning to predict solar and wind energy across Iraq. Results show Random Forest excels for solar (R2 = 0.98) and neural networks for wind (R2 = 0.97), enabling a practical web tool for renewable energy planning. ABSTRACT Driven by the global shift away from fossil fuels, solar and wind resources
