The UK Government has committed to help fund innovative technologies and fuels to reduce maritime emissions and create a zero-emissions sector. The government, in partnership with industry, has committed to spending more than US$8m on funding trials of innovative energy-saving devices, such as state-of-the-art propellers. onboard waste heat recovery and rotor sails that use wind power to cut fuel consumption. In addition to funding trials, the UK Government is now providing technical backing and expertise through the Maritime and Coastguard Agency for the following projects: work in Scotland to prove the use of hydrogen fuel cells for ferries in the UK; and Caledonian MacBrayne Ferries ongoing work to deliver innovative vessels such as hybrids, and its longer-term efforts to prove the use of innovative propulsion and fuels for the next generation of ferries. By 2025, the UK Government expects the majority of new ships to be 30% more efficient than current designs. Reportedly, maritime transport emits around 1,000 million tons of CO? annually worldwide, and is responsible for about 2.5% of global greenhouse gas emissions. If emissions from international shipping are not addressed, studies suggest they will account for almost a fifth (17%) of global emissions by 2050. Maritime minister John Hayes said: The UK is home to a wealth of expertise in maritime technology, but more needs to be done to move this sector towards a zero-emissions world. Thats why this government is committed to backing vital technology to meet this goal, and we are looking to deepen our technical expertise to further support industry.
