Alternative marine energy carrier impact on ship powering and the environment: A comparative conceptual LCA of the operational stage of ship types with alternative marine energy carriers

This thesis investigates the total environmental impact of various alternative marine energy carriers while taking the powering increase into account due to their disadvantageous spatial requirements compared to conventional fuel. A parametric design tool for bulk carriers, tankers, container ships, and trailing suction hopper dredgers has been...

Alternative Energy Carriers in Naval Vessels: Design Options and Implications for RNLN Large Surface Vessels

Climate change and greenhouse gas emissions have been at the forefront of both public and academic debate for some years. Although the shipping industry has managed to remain relatively free of climate regulation this is changing with the IMO goals for 2050. The military sector has also escaped scrutiny on sustainability issues. But this is also...

The effects of country wealth on the energy mix

The total investments in the global energy system amounted to 1.85 trillion in 2018 [1]. Globally over 400 exajoule [2] was provided to energy consumers. The energy consumption is closely related to the emission of green house gasses [3] [4] [5]. In the Kyoto and Paris agreements the international community formalized the intention to reduce the...

Design of a control strategy for optimal operation of an autonomous distributed generation system for electricity and heat

The increasing demand for developments in energy efficiency, the emerging distributed generation technologies like CHP units, the strong development of alternative energy sources such as wind energy, the aim to achieve low production costs, and the new environmental regulations that ask for greenhouse emission reductions are just a few of the...
