Installation of batteries and shore power systems is spreading in the maritime sector, with a record high number of applications to Enova from large fishing boats to service vessels in aquaculture. Battery hybridization has contributed to the introduction of batteries in virtually all vessel segments, but is not a measure that in itself will take us to zero emissions. For many, the transition to zero emissions in the maritime sector will require other solutions in addition to batteries, such as further energy efficiency and the development of zero-emission fuel. Now that batteries have been introduced, Enova is adjusting the support rates in the Battery in Vessels program and directing the focus further on innovation and the development of zero emissions.Just before the summer, Enova announced support for the establishment of five production facilities for renewable hydrogen along the Norwegian coast with NOK 669 million as well as seven ground-breaking hydrogen and ammonia-powered vessels with NOK 451.3 million.Battery in vessels was launched in November 2020. Through a simple application solution, Enova was to contribute to selected vessel segments choosing battery solutions over conventional diesel engines, and support rates are adjusted in line with market developments. Since its inception, Enova has supported a total of 124 aquaculture vessels and 33 fishing vessels through the Battery in vessel programme. Now Enova sees that battery solutions have been introduced in all parts of the maritime market and that several market players offer hybrid vessels as standard. Energy use overall for the sector must be kept as low as possible in the transition to zero-emission solutions, and several vessels are applying for support for energy efficiency measures at the same time as they install batteries.-Commercial use of batteries on board, especially in aquaculture, has progressed faster and to a greater extent than they would otherwise have been, says Fottland, and continues: -Among the largest workboats, longer than 15 metres, we have supported 79 vessels. We receive feedback from the market about increasing demand for climate-friendly service vessels from the aquaculture industry.
