Use of HVO in diesel engines

Hello everyone,

Has anyone of you had any experience using HVO as a fuel? Also, here's the translation:

"Also suitable for longer periods of time when stored in a tank (e.g., in a boat, RV, etc.)."

The DIN EN 590 standard allows for up to 26% HVO blending, and in some countries, blending levels of 40-50% are permitted (Norway, Sweden, California).

"My main interest is in the use of these products in larger diesel engines for trucks and marine diesel engines that are used as stationary power generators. Due to the constant preheating to 40 degrees Celsius and longer storage times in the tanks, there are special conditions here that prohibit the use of regular diesel fuel from gas stations, which contains a biodiesel (RME) blend (diesel plague)." Sometimes, the shelf life of diesel fuel sold at gas stations is only certified to be 90 days.

HVO is supposed to be regarding... Shelf life should be significantly improved.

Who here has relevant experience and would like to share it?

Sure, no problem!

We use ordinary heating oil in our 400kW CHP system, which features a V8 Deutz engine. This is officially approved because the waste heat is also used for heating purposes.

The generator was put into operation in 2006, and later, it was supposedly only allowed to be operated using vegetable oil.

Yes, heating oil free of RME (rape methyl ester) is currently still the best choice for emergency power generation. However, the CO2 issue is being strongly pushed from above, which is why I'm asking about experiences with HVO.

Hello,

After experiencing problems with regular diesel (containing biodiesel) in a parked tractor, where everything seized up, "expensive diesel" was used to flush the system. Okay, so the one without the RME at the gas station.

So far, after 2 years, it looks good, there are no visible leaks, it starts up perfectly, and it still runs after more than 5 minutes.
That's because the fuel filter was clogged before, which is why the Bio-Siff didn't work.

Heating oil also becomes sludgy over time, although much less so than the low-quality fuel containing rapeseed methyl ester (RME).

I would specifically look for a fuel additive from the marine sector, as there are products available that address such problems.

For long-term storage of boat engines or when using small amounts of diesel. The cleaning components contained in the product ensure optimal cleanliness of the entire fuel system. The corrosion protection also included perfectly protects metallic components.

Hi, have you ever thought about GTL diesel?
Since it's made of natural gas, the issue of "diesel plague" shouldn't be a problem.

Our requirement is clear: HVO.
Once again, it's all about that beloved CO2.

Starting in April, there will be HVO Diesel available, which, amusingly, will cost €0.15 per liter more and is subject to the CO2 tax .

Hello,

I know the question is months old, but I just saw it now.

Okay, I develop large diesel engines for industrial applications and marine propulsion. Currently, we also offer emergency generators tailored to specific requirements.

We are currently qualifying some of our product lines for operation with HVO. Of course, emissions and wear are the main focus, but the chemical stability of the fuel is also considered.

The samples that we have been artificially aging intensively for the past 2.5 years show no changes that are relevant for operation.

Our manufacturers state that their HVO has an operational fuel quality guarantee of between 4 and 10 years, depending on the storage conditions. Whether this is true remains to be seen, as one customer recently switched out their emergency generators, which are only started four times a year for testing. So far, no abnormalities.

Kind regards,

Bo.

Thank you for the feedback. We use three-digit number emergency diesel generators with a capacity of approximately 250kVA to 1,000kVA. Engines from Iveco, Volvo, MTU, and other manufacturers.

It's often a nightmare to get approval from engine manufacturers for specific engine serial numbers, especially for the largest systems. It's just inconvenient to have to order two different types of fuel. Mistakes are bound to happen.

It's definitely a good thing that HVO apparently doesn't cause any storage issues.

Okay, so, one of the manufacturers mentioned is based in my hometown. Therefore, there won't be any official approvals for existing products from that company in the future. However, for products introduced after 2014, there might be some progress gradually. Probably not for the classics.

The reasons are varied. The costs for insurance can be enormous. That's something one has to consider today.

Understandable. It doesn't bring the manufacturer anything other than customer loyalty. It's annoying when, as a customer, you're constantly being lectured by the company's self-proclaimed CO2-saving experts about it.

Perhaps this will help you...

Kind regards,

Thank you, that's already a step in the right direction .
