EnviroShips are a zero emissions way of generating clean base load electricity using a ship. The vessels will generate in excess of 300 megawatts of electrical power, and connect to the existing electrical national grid transmission network. EnviroShips will also be capable of capturing the carbon dioxide and storing it onboard before exporting it by pipeline or feeder ship to a storage site. EnviroShips set a path for clean energy production whilst at the same time bringing an intelligent solution to the challenge of Carbon Capture and Storage (CCS). This resolution is a well thought plan that can compete commercially with any other clean alternative available. It will also be the first of its kind in the world, and pioneers offshore base load power.
The 'Inshore' EnviroShip can be moored in a port, on a jetty, next to a quayside or in a drydock. Alternatively, the vessels can be moored in other protected calm water areas such as a bay, fjord, estuary, or a loch.
These vessels will be fuelled through the standard natural gas network, from Liquid Natural Gas brought by carriers, or by standard hydrocarbon based fuels.
The Inshore EnviroShip also has the capability to switch over onto a green fuel source at a later date. The electricity produced onboard will be exported to the national grid network.
The mobility the vessel has enables the national grid voltage drop problems to be controlled through EnviroShips in ports around the country.
The ‘Offshore’ EnviroShip by comparison can be moored a safe working distance from an offshore wind farm and utilise the existing offshore electricity transmission infrastructure that is currently severely underutilised by the offshore wind farm industry, bringing an additional income stream into the Offshore Transmission Owners.
The Offshore EnviroShip uses under-utilised gas fuel sources available offshore such as stranded gas, vented gas, flared gas, or renewable gas. This significantly drives the cost of fuel down to enable clean electricity to be generated offshore commercially and capture the emissions for export to depleted oil fields in the North Sea.
