Hybrid Marine Power

In 2015 two significant developments made many operators, owners and builders of professional vessels consider hybrid marine power and propulsion.

Firstly the new emissions laws in ports and secondly there is now an incentive for high technology manufacturers to invest in developing highly efficient batteries.

Hybrid is ‘here and now’ technology that is being utilised by many industries around the world. The marine industry is now recognising the potential of utilising hybrid power and innovative propulsion systems for vessels in the sub IMO / sub 24 metre professional sector.

Hybrid Marine Technology and Green Ports

‘The Hour Of Power’ has been well received by the marine industry worldwide. This simple concept enables vessels to run in and out of port for an hour on electric with battery power - then carry out their open sea work on diesel power. The aim of this innovative hybrid solution is to enhance conventional propulsion systems. Vessels can reduce emissions and improve fuel consumption whilst extending engine maintenance periods and engine life.

This is not just green energy for the sake of it - ‘The Hour Of Power’ focuses on hybrid solutions linked to viable business cases. For commercial and professional organisations the concept of running vessels with zero emissions at up to 10 knots for one hour will shape decisions that lead to improvements of in-service systems and procurement of next generation vessels. The overall objective is fuel saving and improved efficiency by all means.

The Marine Industry can learn from Automotive & Aviation

For the marine industry to move forward it needs to utilise expertise from aviation and other sectors to drive this innovation and support relevant safety standards. Automotive manufacturers in Europe, the Far East and the US have recognised that hybrid technologies such as PHEV (Plug-in Hybrid Electric Vehicle) utilising lithium ion batteries will be dominant for the next decade.

Reducing emissions from busses and trucks in the world’s major cities has been a major driver for lithium ion battery power storage. The need for self sufficient land based grid applications has further extended the capabilities of next generation battery and hybrid technology.

Serial & Parallel Hybrid Systems

There are two main types of hybrid system. A serial hybrid is where the engine only powers a generator, and is not mechanically connected to the propeller shaft. A parallel hybrid is where the engine is mechanically connected along with an electric 'machine' that can operate as both propulsion motor and generator.

Certain sectors are potentially well suited to hybrid diesel / electric systems. These include wind farm service vessels and pilot boats that have relatively consistent duty cycles. We are entering a period of rapid change and commercial opportunity in the hybrid marine market. End-user organisations, boat builders, engine manufacturers and naval architects are now investigating systems for survey vessels, superyacht tenders, patrol vessels and unmanned craft.

Hybrid Marine Power & Propulsion Conference

Lifeboat College Poole UK – 6 to 8 October 2015

This unique event brings together an international group of experts, to identify the potential of utilising hybrid power and propulsion systems for vessels in the sub IMO / sub 24 metre sector.

Attendees will include professional, commercial and military end-users, boat operators, boat builders, engine manufacturers, mechanical & electrical engineers and naval architects.
