    IWA SUBMISSION ON THE ENVIRONMENT BILL – APPENDIX A IWA VISION FOR SUSTAINABLE PROPULSION ON THE INLAND WATERWAYS EXECUTIVE OVERVIEW 1. Recognising the UK Government’s strategy to reduce emissions from diesel and petrol engines, IWA formed its Sustainable Propulsion Group in 2019 to identify and monitor developments which will enable boats on the inland waterways to fully contribute to the Government’s stated aim of zero CO2 emissions by 2050. 2. The Group has identified a number potential solutions that it recommends should be progressed in order to ensure that boats used on the inland waterways do not get left behind in technological developments. These are outlined in more detail in this paper. 3. To ensure that the inland waterways continue to be sustainable for future generations, and continue to deliver benefits to society and the economy, IWA has concluded that national, devolved and local government should progress the following initiatives: Investment in infrastructure through the installation of 300 shore power mains connection charging sites across the connected inland waterways network. This would improve air quality by reducing the emissions from stoves for heating and engines run for charging batteries, as well as enabling a move towards more boats with electric propulsion. Working with navigation authorities, investment in a national dredging programme across the inland waterways to make propulsion more efficient. This will also have additional environmental benefits on water quality and increasing capacity for flood waters. Research and investment into the production, use and distribution of biofuels. This will be necessary to reduce the environmental impact of existing diesel engines which, given their longevity, will still be around until well after 2050.

  • A Review of Solar-Powered Boat Development
    IPTEK, The Journal for Technology and Science, Vol. 27, No. 1, April 2016 1 A Review of Solar-Powered Boat Development Adi Kurniawan1 Abstract Research in the application of renewable energy has intensified in recent years. The possibility of petroleum extinction in the future is forcing researchers to enhance the utilization of renewable energy resources as a substitute for fossil fuel-based technologies in all fields. Ships as one of the most important transportation in the world also require diesel oil as fuel for main propulsion systems and for diesel generators which supply electrical needs. Solar energy has been considered as the most suitable renewable energy resources to substitute the role of fuel in the ships. In this paper, the latest research on the utilization of solar energy in the ship are presented and analyzed to provide information for the researchers who developed the technology of solar-powered boat. The best possible method to utilize the solar energy in the ship is by using catamaran boat with the flat top structure to provide room for placing solar panel. Furthermore, the solar energy extracted from the panel can be optimized by using quadratic Maximization Maximum Power Point Tracking (MPPT) that executed by KY converter, and converted to AC voltage using a multilevel inverter. The use of quadratic MPPT with KY converter is expected to generate a high output power with small DC voltage ripple from the solar panel while the use of a multilevel inverter is expected to convert the DC voltage into high-efficiency AC voltage before supplied to the electric motor propulsion system.

Ayhan Zora, Deere & Company c American Society for Engineering Education, 2011 An Undergraduate Research Project: The Design and Development of an Environment Friendly Hybrid Boat As the concern for environmental protection of the Earth increases, clean renewable energy resources attract more attention. The technical development of renewable energy such as solar energy, wind energy, wave energy, thermoelectric energy, and kinetic energy (human power) are being pursued on an ever-growing basis. One example of a renewable energy source used for everyday living is the possibility of a propulsion system that combines renewable energy sources (wind, solar, and human power) with the hydrogen fuel cell system for a kind-to-the- environment hybrid boat. Boats which run on battery power have existed for some time. However, the low energy-density in batteries has made it difficult for applications to a larger ship. Accordingly, a system which can be applied to a battery-powered boat has been developed, known as Hybrid Electric Boat (HEB). An 18 ft-length Pursuit 2000 S2 boat was converted to be completely battery powered, with the batteries charged by renewable energy systems such as solar and hydrogen fuel cell systems.

The advantages of all-electric or partial-electric boats are the reductions in pollution, noise, vibration, and potentially, cost. The Nova Scotia marine community has a growing interest in the business opportunities offered by all-electric and hybrid-electric propulsion systems. The Nova Scotia Boatbuilders Association has therefore undertaken this review, which provides a snapshot of the current state of all-electric and hybrid-electric propulsion technology for small vessels – and takes a look at what developments we can expect in the near future. All-electric systems are comprised of an electric motor driven by a battery pack. Hybrid-electric systems include an internal combustion engine, generator, battery, and electric motor, typically allowing the diesel or gasoline engine to do the heavy work when needed, and charge the electric system and allow it to respond to lighter loads such as low-speed cruising or providing power for lights and electronics, and other “hotel” loads. There are many technical challenges associated with the proper design and engineering of all- electric and hybrid-electric propulsion systems, both in terms of current technical limitations such as battery life, charge rate, size, and weight and the larger issue of integrating and controlling the added complexity of hybrid systems and obtaining components that are properly designed and certified for use in a marine environment.

  • The Impacts of High V2G Participation in a 100% Renewable Åland Energy System
    energies Article The Impacts of High V2G Participation in a 100% Renewable Åland Energy System Michael Child 1,* ID , Alexander Nordling 2 and Christian Breyer 1 ID 1 School of Energy Systems, Lappeenranta University of Technology, 53850 Lappeenranta, Finland; Christian.Breyer@lut.fi 2 Faculty of Science and Engineering, Åbo Akademi, 20500 Turku, Finland; alnordli@abo.fi * Correspondence: Michael.Child@lut.fi; Tel.: +358-40-829-7853 Received: 27 July 2018; Accepted: 22 August 2018; Published: 23 August 2018 Abstract: A 100% renewable energy (RE) scenario featuring high participation in vehicle-to-grid (V2G) services was developed for the Åland islands for 2030 using the EnergyPLAN modelling tool. Hourly data was analysed to determine the roles of various energy storage solutions, notably V2G connections that extended into electric boat batteries. Two weeks of interest (max/min RE) generation were studied in detail to determine the roles of energy storage solutions. Participation in V2G connections facilitated high shares of variable RE on a daily and weekly basis. In a Sustainable Mobility scenario, high participation in V2G (2750 MWhe) resulted in less gas storage (1200 MWhth), electrolyser capacity (6.1 MWe), methanation capacity (3.9 MWhgas), and offshore wind power capacity (55 MWe) than other scenarios that featured lower V2G participation. Consequently, total annualised costs were lower (225 M€/a). The influence of V2G connections on seasonal storage is an interesting result for a relatively cold, northern geographic area. A key point is that stored electricity need not only be considered as storage for future use by the grid, but V2G batteries can provide a buffer between generation of intermittent RE and its end-use.
