Rubis Renewable Diesel -FAQs

What is Rubis Renewable Diesel – RD100?

RD100 is an entirely new type of fuel. It is produced from 100% renewable materials so over its lifecycle it can help reduce global greenhouse gas emissions by up to 90%. It is sulphur free, oxygen-free and odourless and is suitable for very cold conditions and can be stored over long periods without deterioration in quality or water accumulation, unlike some 1st generation biofuels.

How is it made?

RD100 is produced using waste fats, residues and vegetable oils and is classified as a Hydrotreated Vegetable Oil. RD100 has an identical chemical structure to regular diesel and can therefore replace fossil diesel today. It has better combustion, filterability and cold temperature resistance meaning it is better for diesel vehicles, particularly in Jersey where most journeys are short, and engines don’t always reach full operating temperature.

Does RD100 contain Fatty Acid Methyl Ester (FAME)?

RD100 uses the same feedstocks as FAME but a different refining process that removes some of the issues experienced with FAME such as microbiological growth, long-term stability problems, water contamination and in some circumstances, higher vehicle maintenance costs.

Does RD100 contain Palm Oil?

Yes, RD100 contains a small amount of palm oil, up to 7% in 2021. We have the intention of 0% palm oil in RD100 by 2023.

We have selected to work with a refinery that only uses a small amount of sustainably grown palm oil. The palm oil is sourced from farms which are traced and audited and only use trees which are over 10 years old.

The refinery, Neste, is a member of RSPO and the palm oil used is RSPO certified. Neste requires all their palm oil suppliers to be members of the Roundtable on Sustainable Palm Oil (RSPO) organization. The organization requires its members to commit themselves to respecting human rights and protecting rainforests.

The WWF highlights that as the palm oil is RSPO certified it ‘give you the confidence that the palm oil was produced in a socially and environmentally responsible way.’ More from the WWF can be found here.

What does sustainably grown and traced mean?

Renewable Diesel is available from many distributors and refiners , some of them still use a significant proportion of palm oil in there feedstock.

That is why Rubis has decided to source its Renewable Diesel directly from Neste, a company who has managed to transform from a regional oil refining company into a global leader in renewable fuels.

Neste’ raw material feedstock is made of more than ten different raw materials and is focusing on waste and residue oils. However Palm Oil still accounts for approximately 20% of the raw material feedstock.

All of it is certified and fully traceable and represents less than 0.5% of the global consumption of palm oil, and less than 3% of the global consumption within the biofuel industry.

Traceability goes all the way to the plantation level. Oil is sourced carefully from screened, responsible producers in Malaysia and Indonesia that are committed to certification and principles of sustainability. Palm oil is sourced directly from the producer companies instead of purchasing separate certificates from the world market.

Rubis and Neste share the same value of regularly engaging directly with their own suppliers. Buying directly provides better transparency and influence in the supply chain – the more direct the supply chain, the better.

Rubis chose Neste because they transparently disclose their forest footprint as part of the CDP Forests program. In January 2019, Neste’s deforestation risk management performance was evaluated as belonging to the leading performers lists.

Why is it good for reducing carbon emissions?

Because RD100 is produced from 100% renewable sources, over its lifecycle it can help users reduce greenhouse gas emissions by up to 90%, when compared to conventional diesel. The carbon dioxide released through combustion offsets the amount that the renewable source has absorbed earlier, bringing greater balance to the carbon lifecycle.

RD100 does not add additional carbon into the atmosphere; this is the key benefit when compared with products based on fossil fuel like diesel and 1st generation biofuels. There is no Carbon extracted from the ground.

How will it help me make an impact on climate change globally?

RD100 will help reduce local traffic emissions, in particular with vans and trucks in town. This is especially beneficial when you consider most local drivers make short journeys and spend a lot of time in traffic congestion, especially at the start and end of the day. Scientific studies show that when RD100 is used in its 100% renewable form it can result in:

RD100 will help reduce local carbon emissions immediately and the older and less developed the engine is, the greater the impact will be.

I have a diesel vehicle, can I use RD100 now?

RD100 can be added to your tank now and drivers of diesel vehicles can start to reduce their emissions immediately. RD100 is fully compatible with the existing fuel distribution infrastructure. It can be used as 100% renewable diesel or blended with conventional diesel, which means you can put it in your tank now and there is no need for any modifications to your vehicle.

If you have any concerns it is always worth speaking with your vehicle manufacturer.

Will my engine performance be affected?

RD100 may actually improve your engine performance because it has a higher cetane rating than conventional diesel (70 vs 50) and therefore operates more efficiently with cleaner combustion.

Why is Rubis introducing this fuel?

Rubis is a local business and has been supplying high quality fuels in the Channel Islands for over 65 years. We have always moved with the times and invested in our infrastructure to make sure our products and services are of the highest possible standard.

We recognise the global climate emergency and the contribution to this of fossil fuels. We are committed to helping our governments meet their commitments to reduce carbon emissions in the most practical way, particularly in the two main areas of our business: fuel for home heating and for road and marine use.

Because we are part of a global company, we are now able to use our purchasing ability and international reputation to introduce RD100 to the local public, commercial and private transport sector.

How is RD100 different from other biofuels?

Unlike some 1st generation biofuels containing FAME, which are blended into fossil fuels, RD100 does not have to be blended and meets the toughest requirements set by the automotive industry, avoiding the storage issues sometimes associated with them. It is fully compatible with all modern diesel engines in cars, buses, trucks and non-road machinery and is also suitable for marine and shipping clients, who have so far had to avoid using biofuels with FAME.

At a local level the exhaust emissions will improve air quality when compared to 1st generation biofuels and fossil diesel; there is a significant reduction in particulates, NOx and carbon monoxide. Then at a global level the carbon emissions are reduced by up to 90%, due to no new carbon being released in the atmosphere during the lifecycle of the fuel, creating a virtuous global carbon cycle.

Why shouldn’t I just switch to electric?

At the moment everyone is talking about electric vehicles and, of course, they are one option as part of the mix of opportunities to cut carbon emissions. But they are expensive to buy, not in plentiful supply and may not be the best long-term solution, because of the environmental and financial cost of building, replacing and recycling the batteries and the amount of new infrastructure that has to be invested in to encourage mass adoption.

The amount of carbon emissions related to car manufacturing and recycling is significant, sometimes even more for long range EVs and its batteries; keeping your existing car avoids it.

This may not be a challenge locally but for people who want to take their vehicles to the UK or Europe, range is a concern. Significant sums need to be invested to make electric vehicles a common reality on our roads

Many vehicles that currently run on conventional diesel will still be on the roads for years to come so we are in a transition period and nobody can say how long that will last. RD100 can have an immediate impact and start reducing carbon emissions during this transition period.

More likely fuels such as renewable diesel and in the future hydrogen cell technology will provide a more sustainable answer in the longer term.

Where can I get it?

Rubis are currently supplying selected forecourts in Jersey and Guernsey with more forecourts expected to come on board shortly.

We can also supply direct to businesses in both islands for their fleet vehicles.
