High-quality, environmentally friendly diesel substitute fuel: Roth Werke expands its range of sustainable container systems

All tanks are "Green Fuels Ready"

Flexible and sustainable: Roth Werke in Central Hesse offers consumers a future-proof solution for climate-friendly mobility and environmentally friendly oil heating in turbulent political times.

The manufacturer of energy and sanitary systems not only offers heat pump systems and solar solutions, but also actively conducts research in the field of alternative synthetic fuels, known as "green fuels". With success: The Roth tanks "KWT", "DWT" and the "Unitech and Multitech" tank series specially developed for the industrial sector, including the associated filling systems, have been officially approved by the German Institute for Building Technology for the use of these alternative fuels, thus emphasising the use of "green fuels"

Today's container creates safety for tomorrow

"A decisive step for our container division," emphasise Business Unit Manager Christian Roßbach and Sascha Allissat, Member of the Management Board of Roth Werke. "With our tanks and containers of today, we are securely positioned for the fuel of tomorrow.

HVO100 ("Hydrotreated Vegetable Oil") is a synthetic diesel fuel. It consists of residual products such as used cooking oil or used vegetable oils. During production, the fuel undergoes a hydrogenation process in which oxygen is removed and hydrogen is added. HVO100 is 90 percent climate-neutral, produces significantly fewer particulate emissions and is practically odourless. HVO100 burns cleaner than fossil diesel and has technical advantages such as very high cold resistance and long shelf life. The fuel can be mixed with fossil diesel in any ratio, making its use particularly flexible and attractive.

Roth Werke was the first manufacturer in Germany to receive "Green Fuels Ready" approval for its tanks and associated filling systems last year. The Roth small tank systems, which are used by farmers and others, are also "Green Fuels Ready" - and therefore also "HVO100 Ready".

"A real milestone, especially for drivers who want to travel long distances in a climate-friendly and environmentally friendly way," emphasise Christian Roßbach and Philipp Wagner, Technical Sales. In his discussions with interested parties, he has noticed an increasing demand for HVO100-compatible systems: "Mobility is essential for people, while at the same time more and more drivers are looking for ways to be  climate-neutral when travelling." 

Fit for fuel and versatile applications - also with transport approval

It is also conceivable that heating systems will increasingly be operated with HVO100 or other bio-based, renewable fuels in a climate-friendly manner in future. "The Building Energy Act already stipulates a mandatory increase in the proportion of renewable fuels for oil-fired heating systems installed during the transition period until municipal heat planning is finalised," explains Christian Roßbach. Sascha Allissat adds: "With HVO100, there is already a widely available technical solution for this, which, as a biogenic fuel, would also be exempt from CO2 pricing."

Plastic tanks that have been filled with fossil fuels for decades

However, tanks that have been refuelled with fuels should not be filled with pure HVO without further ado. For older tanks, it is generally advisable to switch to new double-walled plastic tanks

The Roth "KWT" double-walled plastic sump tank is an all-plastic product with an inner tank and integrated polyethylene (PE-HD) drip tray. In the Roth double-walled "DWT" tank, an integrated drip tray made of fully galvanised sheet steel encloses the PE container. This steel-plastic composite solution has proven its worth for more than 30 years, especially in private applications, and is still considered to be up to date.

Roth completes its delivery portfolio with a double-walled tank with UN transport authorisation which, thanks to its dimensions, is particularly versatile in the commercial sector.

"We are also seeing increased interest in HVO 100 in the industrial sector. With our Roth Multitech tank series, we can offer a fully approved tank that can be used as a stationary tank and also keeps our customers mobile," says Sales Engineer Philipp Wagner. "Roth offers the perfect solution for transporting and storing climate-neutral fuel, especially for energy-intensive applications such as agriculture with large machines or construction site heating systems," adds Christian Roßbach

Synthetic fuels offer numerous advantages

The German Institute for Building Technology certifies the unrestricted suitability of Roth heating oil tanks for alternative fuels in accordance with DIN EN 15940 and DIN/TS 51603-8: so-called "green fuels", which are produced using renewable energies and produce significantly fewer harmful emissions than conventional fossil fuels. These include hydrogenated vegetable oils (HVO), hydrogenated used oils (HUCO) and "Fischer-Tropsch synthesis" products. These fuels not only help to reduce greenhouse gas emissions, but also offer other significant advantages: For example, higher energy efficiency, better environmental compatibility and greater independence from fossil fuels

"The approval of our tanks for so-called "green fuels" underlines our diverse development activities in the field of sustainable energy systems," emphasises Christin Roth-Jäger, Managing Partner of Roth Werke.
