INDUSTRY NEWS: Innovation from North-East pioneering green technology company on track to revolutionise decarbonisation of vessels

Oasis Marine, a small company in North-East Scotland, is leading the way in the decarbonisation of vessels with pioneering technology.

Initially providing a successful range of smaller mooring buoys, Oasis Marine has developed several industrial solutions, the Oasis Hydrogen Buoy and the Oasis Power Buoy, to provide offshore hydrogen bunkering and electric charging, allowing vessels to switch from diesel to green power.

The ground-breaking technology, using hydrogen for offshore bunkering, is thought to be a first for the industry.

The Oasis Hydrogen Buoy will be able to transfer green hydrogen produced by offshore wind farms, potentially becoming part of an offshore hydrogen highway, whereby hydrogen is stored at an offshore location before being transferred by buoy to vessels transporting hydrogen or using it as their fuel source.

It is estimated that shipping currently produces more than three percent of all CO2 emissions and the industry has been set a global decarbonisation target of a 20 percent reduction in emissions by 2030, rising to 70 percent in 2040, with full decarbonisation by 2050.

George Smith, Managing Director of Oasis Marine, said the Oasis Hydrogen Buoy and the Oasis Charging Buoy have huge potential in reducing the global shipping industry’s CO2 footprint.

“These buoys will have a tangible impact in our shift from hydrocarbons towards a green energy future,” he said. “Initially we are looking at deploying them in the North Sea offshore wind market.

Currently windfarm maintenance vessels rely on fossil fuels and make up the largest component of an operational windfarm’s carbon footprint. While that will be our initial focus, the technology could be applied to other vessels across the maritime industry.

“The maritime energy mix of the future won’t be a single solution but will be made up of different renewable sources. Our Oasis buoys deliver two of those through hydrogen and electric charging, both of which come from renewable, low-cost energy generated by wind farms.”

With funding and support from the Scottish Government via the Emerging Energy Technologies Fund (EETF) Hydrogen Innovation Scheme (HIS), mooring analysis of the hydrogen buoy was tested as part of the TestHOTS (Tank Testing of Hydrogen Offshore Transfer System) project demonstration.

The demonstration, at the Kelvin Hydrodynamic Laboratory in Glasgow, showed how the mooring buoy connects to vessels and scale model tank testing gathered valuable technical data such as the impact of wave conditions and sea states on mooring loads while bunkering.

The project has already optimised the Oasis Hydrogen Buoy from numerical analysis and aims to further validate these findings from the wave tank testing. The demonstration followed a Clean Maritime Demonstration Competition (CDMC1) project, funded by the Department of Transport through Innovate UK, which allowed Oasis Marine to develop the design of the hydrogen buoy and prove the concept viable.

Oasis Marine partnered with Strathclyde University and ship owner O.S. Energy to conduct the hydrodynamic analysis and wave tank testing. One of O.S. Energy’s vessels is being retrofitted for hydrogen fuel and a model of the ship was used during the demonstration and tank tests.

Martin Nuernberg, Managing Director of O.S. Energy UK added: “The development and validation of technologies like the hydrogen buoy will enable our vessels to transition to cleaner alternative fuels and have significant impact on the offshore endurance of our fleet.”

AREG is the original energy transition organisation, working on behalf of members to empower the energy supply chain and champion its expertise. Please get in touch if you have any questions or would like to find out more about membership.

AREG has played an important role in the growth of Scotland’s renewable energy sector, engaging the supply chain and developing the European Offshore Wind Deployment Centre. However, we are only at the very beginning of the transition that AREG was established to both lead and support so there are still opportunities for companies to get into the constantly evolving renewables supply chain. We look forward to continuing our work together as renewables builds on its place as Scotland’s main source of power, and as we seek to deliver real change in the crucial areas of heat and transport.

Aberdeen & Grampian Chamber of Commerce has worked closely with AREG since its formation. The recent progress in the developments of offshore wind projects by Equinor and Vattenfall are as a result of the work of the group over many years. The north-east is known as the oil and gas capital of Europe. At the Chamber, we believe the region must evolve its position to being recognised as the energy capital. Whilst hydrocarbons will continue to be essential in driving our economy for years to come, the generation of renewable resources will play an increasingly important role in providing cost-effective power, innovative development and economic growth.

The enthusiasm and dedication of the early group that would become AREG was fundamental in us choosing to launch All-Energy in Aberdeen. The first tiny show was held in 2001, and AREG’s Chairman at the time, Jeremy Cresswell, played such an active role that I often describe him in terms such as All-Energy’s ‘midwife’. All-Energy is now the UK’s largest renewable and low carbon energy exhibition and conference in terms of number of attendees, space booked, and number of exhibiting companies. As AREG became firmly established, their presence and support for the event grew spectacularly over the years. We thank them most sincerely for their invaluable input.


Vattenfall has forged a strong working relationship with AREG through the development of the European Offshore Wind Deployment Centre. AREG has worked tirelessly on behalf of the North East and it can take enormous credit for the growth of sustainable energy in the region and the path it has cleared for the region to capture further investment.


Aberdeen City and Shire is emerging as a key location for renewables by successfully transferring its world-class oil and gas expertise into the sector and AREG has done much to advance this through a broad range of initiatives. It has acted as a catalyst in driving further investment in the local economy by engaging with companies, Government, public bodies and existing projects and we have been pleased to support their efforts. Scottish Enterprise will continue to engage with AREG as we increase Scotland’s use of renewable energy.
