Diesel Substitution with Hydrogen for Marine Engines
Modelling and Optimisation of Ship Energy Systems 2023, 2023 Zero-carbon fuels are expected to catalyse the decarbonisation of the maritime industry, with hydrogen being considered a long-term solution. This study aimed to investigate the feasibility of using hydrogen as a secondary fuel in marine diesel engines.

Simulation of the dynamics of a marine diesel engine [PDF]
Journal of Marine Engineering & Technology, 2009 This paper presents a simulation model of a turbocharged four-stroke diesel engine with eight cylinders in transient conditions, attached to a propulsion system. Having an engine model that is accurate but not complicated is desirable when working with on-board diagnosis or engine control. The model presented here is relatively simple, but sufficiently

Business Strategy and the Environment, EarlyView.ABSTRACT This study investigates how directors with environmental protection (EP) backgrounds influence corporate biodiversity concern (BIO) among Chinese A‐share listed firms from 2008 to 2023. Drawing on Upper Echelons Theory, we argue that directors' environmental expertise shapes firms' biodiversity strategies.

Business Strategy and the Environment, EarlyView.ABSTRACT Global imperatives, such as climate change, environmental concerns, and carbon emissions, make green transformation an inevitability in the logistics sector. Green logistics strategy formulation is an economic choice problem, but it also turns out to be a multicriteria decision‐making (MCDM) process that encompasses the triple bottom line (TBL)

Carbon emission assessment of tunnel infrastructures: From construction to operation
Deep Underground Science and Engineering, EarlyView.This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...
