Haveblue is independent of energy production and distribution infrastructures because the entire process occurs onboard the vessel, utilizing reliable, “off-the-shelf” systems and equipment. Here is a basic description:
PRODUCTION AND STORAGE
- A marine vessel obtains water from where it happens to be afloat (if necessary, it can also obtain water from a public utility).
- A standard water purification device processes the water to the required level of purity. (Some hydrogen generation devices do not require such processing.)
- An electrolysis unit produces hydrogen and oxygen from the purified water.
- The hydrogen is stored as compressed gas or in metal hydride tanks. (“On demand” hydrogen generators, when they become available, may also be used.)
USING THE HYDROGEN
- Hydrogen-consuming fuel cells (working with the vessel’s battery bank, much like in a hybrid automobile) produce electricity for onboard needs and/or propulsion
- An internal combustion engine burns the hydrogen to produce power for propulsion and/or to generate electricity for onboard needs and/or propulsion.
POWERING THE PROCESSES
- Renewable energy sources such as solar, wind, and/or a vessel’s regenerative electric motor primarily power the production and storage of hydrogen while the vessel is at rest and/or underway.
- Shore-power and power from high-output marine alternators can also be used.
HaveBlue can be configured to produce the energy needed to power a vessel’s propulsion and “hotel” energy needs, just service its “hotel” needs, or help marine vessels reduce their emissions by injecting hydrogen into their fossil-fuel combustion processes.
