With an increasing emphasis on emission restrictions and environmental impact of carbon-based energies, transportation industries are rapidly focusing on research, development, and implementation of zero-emission fuels and technologies. In the United States, the maritime industry provides key transportation services for people and goods. Immediate and future legislation at the state and federal levels are beginning to push passenger vessel operators to seek more carbon-neutral propulsion methods and begin the necessary transition towards a zero-emission future. Small high-speed, zero-emission vessel concepts are being introduced in the United States, most notably the SWITCH project of San Francisco. The SWITCH project aims to put the first hydrogen fuel cell e-ferry into service in 2021. To date, the zero-emission fast ferry efforts have focused on smaller passenger vessels. This paper examines the potential design elements and operating conditions required for a large (450 passengers) high-speed vessel to meet zero-emission standards. Key ferry metrics of speed and passenger capacity are studied with this concept hull to compare a zero-emission propulsion system against a more traditional carbon-based system. To account for major project decision factors, the economics/cost and regulatory restrictions of a hydrogen fuel cell system are considered for a high-speed passenger vessel of this scope. A sensitivity analysis is performed to determine the technological and performance gains necessary for fuel cell power to match the current capabilities of carbon-based powers. Future development of zero-emission technologies is discussed to evaluate the continually improving opportunities for such a large high-speed vessel.

Energy Mix

As a party to the United Nation Framework Convention on Climate Change (UNFCCC), Malaysia is committed to reduce its greenhouse gases (GHG) emission intensity of gross domestic product (GDP) by 45% by 2030 relative to the emission intensity of GDP in 2005. One of the ways for Malaysia to reduce its GHG emission is to diversify its energy mix and to include hydrogen fuel cell (HFC) in its energy mix. Since Malaysia does not have any legal framework for HFCs, it is best to see how other countries are doing and how can it be replicated in Malaysia. This paper reviews the HFC legal framework in the United States, Germany and South Korea as these countries are among those that have advanced themselves in this technology. The researchers conducted a library-based research and obtained the related materials from online databases and public domain. Based on the reviews, the researchers find that these countries have a proper legal framework in place for HFC. With these legal frameworks, funds will be available to support research and development, as well as demonstration of HFC. Thus, it is recommended that Malaysia to have a proper HFC legal framework in place in order to support the development of the HFC industry.

Structured Interviews

Hydrogen fuel cell vehicles (HFCVs) are zero-emission vehicles (ZEVs) and their widespread adoption may help to mitigate some of the issues arising from fossil-fuel usage in the transportation sector. Only in recent years have these vehicles become available for purchase or lease in the United States, and only within the State of California. In 2018, nearly 5,500 HFCVs had been sold or leased in California, supported by a developing refueling infrastructure there. This population represents a unique opportunity, as previous studies on HFCV adoption have largely employed hypothetical stated preference surveys distributed to likely adopters. Seeking to investigate the real experiences of actual adopters from their own perspectives, semi-structured interviews were conducted with 12 early adopters of HFCVs in the Los Angeles metropolitan area. Thematic content analysis of these interviews was conducted to identify the prevalence of factors deductively derived from published literature. All respondents considered lifetime cost of vehicle ownership, engaged in comparison shopping, and assessed the adequacy of the refueling infrastructure by various geographical criteria. Environmental concerns motivated many respondents to pursue HFCV adoption, though only if it made financial sense. Respondents chose HFCVs over battery electric vehicles after consideration of range, refueling time, and cost. Early HFCV adopters consistently cast their adoption of the technology as a contribution to a diverse ZEV marketplace. Strategies for the promotion of HFCV technology must account for this range of variation in early-adopter motivations, concerns, and behaviors which might complicate targeted HFCV promotion strategies.

Introduction. The gradual and relentless development of alternative energy sources and the constant strug-gle of humanity with excess greenhouse gas emissions led to the simultaneous development of vehicles with alternative energy sources. Currently, vehicles that run exclusively on electricity and are virtually safe for the environment are becoming increasingly popular. Among the variety of vehicles running on electricity, it is necessary to single out vehicles that use compressed hydrogen to generate electricity. Hydrogen fuel cell vehicles (HFCV) are already widely used in the United States, Germany, Japan, and the rest of the world, and their governments are constantly expanding and developing the appropriate infrastructure for them.The purpose and objectives of the study. The paper analyses the basic structure of HFCV and identifies the main scenarios of possible emergencies, namely: fire or explosion of fuel tanks with hydrogen; leakage, flaming of hydrogen from fuel lines (tank) under the high pressure; high-pressure hydrogen jet fire; leakage of hydrogen in the compartment (garage, closed parking) without further combustion.Methods. In the work on the subsequent literature review, the probable dangers for the personnel of the emergency rescue units involved in the elimination of certain emergency scenarios were identified.Results. It is established that: during the combustion of HFCV the most probable jet fire of hydrogen (flame temperature can reach 2000 0C), and also possible explosion of hydrogen cylinders or gas-air mixture with a significant range. Secondly, leakage of hydrogen in the compartment can cause its destruction in a relatively short period (about 15 seconds), and/or poisoning (asphyxia) of people due to a sharp decrease in oxygen concentration.Conclusions. The analysis and generalization of existing knowledge on the potential hazard of HFCV is conducted, electric cars give us reasonable grounds to argue that the regulatory framework for the construction and installation of security systems for land and underground parking, places of accumulation of such vehicles is not adapted to today's realities. At the same time, the following studies should be directed at estimating probablee risks of such emergencies.
