Williams Jet Tenders

Williams Jet Tenders has approved HVO100 fuel (hydrotreated vegetable oil) after successful first-stage testing on selected DieselJet engines.

HVO is a diesel-like fuel made from renewable waste, residue and vegetable oils. The environmental benefits of Used Cooking Oil (UCO) HVO fuels include reduced greenhouse gas emissions, fewer particulates, sulphur and nitrogen oxides than conventional diesel, and reduced air pollution.

Williams has approved HVO100 for use on all its Yanmar 4JH engine-powered tenders, including the DieselJet 415, 445, and 505, and SOLAS 505. The firm says it encourages customers with these engines to use HVO100 fuel to reduce their carbon footprint, as it can decrease emissions without impacting performance.

As a result, all new product developments and product testing powered by these diesel engines will utilise HVO100. Williams’ fleet of vehicles, including delivery vans and lorries, as well as the Yanmar 4LV powered models, are also looking to transition to HVO100 once further testing has been completed.

“We are committed to finding innovative sustainable solutions that reduce the direct emissions impact from our factory and our vehicles,” says Sarah Moore, sustainability specialist at Williams Jet Tenders. “By using UCO HVO, a renewable fuel made from waste cooking oil, we will accelerate our efforts to decarbonise.

“We hope that by using HVO in our fleet and in our approved test boats, we will raise awareness of the benefits of switching to alternative fuels. As we carry out exploratory testing on our products, it will allow us to confirm HVO use in more of our tenders, enabling us to achieve a greater reduction in our carbon footprint as more Williams Jet Tender engines are approved for use.”

Floris Lettinga, director of sales and marketing at Yanmar Marine International adds: “Yanmar Marine International is proud to partner with Williams Tenders, a collaboration perfectly aligned to Yanmar’s commitment to sustainability.

“By integrating Yanmar’s HVO-approved engines across the Williams Tenders’ range of boats and vehicles, we are not just propelling innovation; we are supporting our customers in propelling a sustainable journey towards a cleaner future.”

Williams says the announcement is part of its broader commitment to sustainability. The firm was recently awarded a grant by Innovate UK Edge to test alternative, more sustainable composite materials and complete Life Cycle Analysis (LCA) for its TurboJet 325 and DieselJet 415 to calculate their carbon footprint.

Williams Jet Tenders also hired Moore as its full-time sustainability specialist in 2023. It says further sustainability updates will be released in 2024.
