Calor, which is part of the European SHV group, is intent on switching to renewable sources of these fuels by 2040 and as such is investing heavily in research in the various production pathways for these advanced fuels both BioLPG and Biomethane/Synthetic Natural Gas.

Argent Energy (UK) Limited

Argent Energy has been producing biodiesel since 2005. The first plant in Motherwell, Scotland was the demonstration plant for Europe and the first commercial plant to use waste animal fats. Their second plant in Ellesmere Port, England includes further technology developments and enables them to produce top spec biodiesel from the very worst and degraded waste fats and oils, including fatbergs. Argent also acquired a biodiesel plant in Amsterdam in 2018 bringing their total production capacity up to 230,000t/yr.

Argent’s fuel is sold in the UK and across Europe. In the UK they have developed a blending and supply service for high biodiesel blends to allow fleet operators to make huge GHG savings at a competitive price to standard diesel.

ALCOGROUP SA

With headquarters in Brussels and operations on several continents, Alco is one of the biggest producers and distributors of ethanol for fuel in Europe. Globally we provide ethanol to various industries: from cosmetics to pharmaceuticals, biochemistry, food and beverage.

Electricity

The attraction of an electric drive train is that there are zero tailpipe emissions. The well to tank emissions from an electric vehicle will depend on how the electricity is produced.

The production of electricity from any form of combustion source results incurs losses of around 40 to 50%. Renewable electricity from non-thermal sources such as wind and solar, is not subject to these losses. The transmission and distribution of electricity results in further losses of energy (around 8%).

During the recharging process there are further energy losses (up to 12%) in the cable and the battery itself. (This is why it is difficult to fast charge a Nissan Leaf in hot weather as their batteries are air-cooled).

Electricity has no fuel duty and pays VAT at 5%.

Renewable Fuels of Non-Biological Origin (RFNBO)

Renewable hydrogen is the most straight-forward RFNBO. Renewable hydrogen can be reacted with CO₂ and synthesised to produce more complex liquid hydrocarbons via the Fischer–Tropsch process. These are referred to as e-fuels or paraffinic diesels.

Hydrogen

The attraction of hydrogen is that it has zero harmful tailpipe emissions when used in a fuel cell, and vehicles using it can be refuelled quickly and have a long range. Set against this are the energy losses involved in producing the hydrogen.

There are various different ways of producing hydrogen, and the upstream (or “well to tank”) emissions vary significantly depending on the production pathway. Renewable hydrogen can be made by electrolysing water using renewable electricity. This is the simplest form of a Renewable Fuel of Non-Biological Origin – or RFNBO for short. Another route for making renewable hydrogen is from syngas produced from biomass. This is known as biohydrogen.

Hydrogen from steam reforming natural gas requires carbon capture and storage in order to be a low carbon proposition.

For use in fuel cells the hydrogen has to be extremely low in moisture and very high purity (99% plus), but if used in an ICE the purity requirement is less stringent. At standard room temperature and pressure hydrogen has one third the calorific value of natural gas and half the calorific value of diesel. Pressurising and then storing hydrogen in excess of 700 bar to enable high-pressure filling is energy intensive.

Hydrogen currently pays no fuel duty but does incur VAT at 20%.

Sustainable Aviation Fuel

SAF is a low carbon alternative to kerosene jet fuel.

Aviation fuel has stringent specification criteria and fuels must be certified in order to be used in commercial flights. There are a number of aviation fuels derived from biomass that have been certified, and several others are in the approval process. SAF can be made from oil-based feedstocks such as Used Cooking Oil. SAF made this way is referred to as HEFA (Hydrotreated Esters and Fatty Acids). It can also be made from wastes, such as residual Municipal Solid Waste (Waste-to-SAF); renewable hydrogen and carbon dioxide (Power-to-SAF or e-SAF) or from recycled carbon sources, such as industrial off-gases e.g. from steel production. This process involves fermenting the off gases to make ethanol, which is then synthesised into aviation fuel via A2J (alcohol to jet) technology. Renewable bioethanol sources can also be used for A2J.

Drop in fuels

Any renewable or sustainable fuel that can be blended with conventional fossil fuels at any level, whilst still meeting the relevant fuel standard (be that for petrol, diesel, aviation or gaseous fuels) is known as a “drop in” fuel. The Department of Transport regards renewable liquid drop in fuels that can be blended with petrol and diesel as strategically important, and is encouraging their development through the Renewable Transport Fuels Obligation via the development fuels sub-target. Biomethane made from the thermal treatment of wastes, as being developed by Advanced Biofuel Solutions Ltd at its Swindon plant is also regarded as a development fuel.

To qualify as development fuels, these fuels must be made from wastes or residues, but not feedstocks that typically go to make biodiesel (i.e. not made from segregated oils or fats). They can also be made from renewable fuels of non-biological origin. See below.

A typical feedstock for producing this fuel would be residual waste. This is a mixture of biomass waste and waste plastics that cannot be recycled. The resulting fuel would be partly renewable, and partly recycled carbon fuel.

Recycled carbon fuels

Recycled carbon fuels are liquid and gaseous fuels produced from liquid or solid waste streams of non-renewable origin which are not suitable for recycling, or from waste processing gas and exhaust gas of non-renewable origin which are produced as an unavoidable and unintentional consequence of the production process in industrial installations.

Fuels such as that which RTFA member Velocys is developing will be made from municipal solid waste. This is a mixture of biomass (roughly 65% by energy) and non-recycled plastics. The resulting fuel would be a combination of renewable and recycled carbon fuel.

The Department for Transport is considering whether to include these fuels within the Renewable Transport Fuel Obligation. The EU Renewable Energy Directive allows Member States to support recycled carbon fuels alongside renewable fuels, provided they achieve a minimum greenhouse gas saving threshold. The threshold and the methodology for determining it will be agreed by the end of 2021, under a delegated act.

HVO (Hydro-treated vegetable oil)

HVO is a drop in fuel, closely aligned to the chemical composition of diesel and with identical performance characteristics. Warranty concerns are therefore not an issue. GHG savings are typically around 90%.

HVO is made from similar feedstocks to biodiesel, but is more expensive to produce. There is no UK manufacture of HVO, although facilities are planned.

HVO pays full fuel duty (57.95 pence per litre) and VAT at 20%.

Biomethanol

Methanol is the simplest alcohol, with one carbon atom. It is also known as wood alcohol or methyl alcohol. It is used as a fuel, as a solvent and in antifreeze. Bio-methanol, the renewable form of ethanol, can be produced from syngas from the gasification of biomass and wastes, from biogas, or from reacting CO₂ with hydrogen. It can be blended with petrol and diesel, used as feedstock for other derivative fuels such as DME or used as a bunker fuel for shipping. It can also be used in fuel-cells. In comparison with bioethanol it has lower energy density and is poisonous for human consumption. It is used in the UK at about 1/10^th of the volume of bioethanol.

Biopropane (the renewable equivalent of LPG – liquefied petroleum gas)

LPG is a fossil fuel, and biopropane is the renewable equivalent. RTFA member Calor Gas Ltd supplies biopropane for both transport and heating. Biopropane is a by-product of the production of HVO. LPG is a mixture of propane and butane and is a by-product of natural gas and oil extraction and oil refining. It boils at a low temperature and is stored in pressurised steel vessels such as gas bottles or bulk LPG tanks. It can be used as a vehicle fuel, and is particularly used in forklift trucks.

Both LPG and Biopropane pay fuel duty of 31.61 p/kg (equivalent to 16.65p/litre) and VAT at 20%.

Biomethane (the renewable equivalent of natural gas)

Methane is increasingly used to fuel heavy duty vehicles in the UK. It is used in cars elsewhere (particularly in Italy) but this is not envisaged for the UK. Fossil methane, or natural gas can achieve a GHG saving of around 15% compared to diesel, but the renewable equivalent, biomethane, can achieve savings in the region of 85% – 110%. Biomethane achieves negative carbon emissions when produced from animal manure, as it is captured instead being released into the atmosphere during manure storage. Member companies CNG Fuels Ltd and Gasrec supply biomethane in the UK, and Advanced Biofuel Solutions Ltd will produce biomethane at its Swindon Plant.

It is used either in compressed from or liquefied, and predominantly in 42 tonne Heavy Goods Vehicles (HGVs). We will talk about biomethane from now on. Compressed biomethane requires more storage space on the tractor, and is generally used on 2 axle tractor configurations. Compressed biomethane is stored at pressures of [250bar], whilst liquified is stored at 5 – 10 bar but requires refrigeration at around -160 Celsius.

Compressed biomethane (CBM) may be supplied directly or via mass balance. LNG will always be mass balanced. Mass balancing in this context is putting biomethane in the gas distribution grid in one location, and taking an equivalent amount of gas out in another location, but having the sustainability characteristics of the biomethane follow the contractual pathway taken by the gas.

Natural gas and Biomethane both pay a fuel duty of 24.7p/Kg and VAT at 20%. This fuel duty rate is fixed to 2032, with a review in 2024.

Bioethanol

UK produced bioethanol can achieve GHG savings of over 85%. Bioethanol is made from fermenting starch rich biomass (such as feed wheat or corn). This process produces ethanol with by-products of CO₂ (which can be sold for use in the drinks industry) and DDGS. DDGS stands for distillers dried grains and solubles, and it is a protein-rich solid which is used as an animal feed. Feed wheat is high-starch, low-protein grain which is unsuitable for making milling flour for human consumption. The fermentation process turns the starch to alcohol, and concentrates what protein there is in the DDGS making it a superior animal feed in comparison with the unfermented grain.

There are three bioethanol facilities in the UK, Ensus UK Limited in Teesside, British Sugar in Wissington and Vivergo at Saltend, Hull. also owned by Associated British Fuels. Alcogroup manufactures ethanol at two facilities in the Netherlands. Nova Pangaea Technologies (UK) Limited is developing technology for converting lignin-rich feedstocks into ethanol, along with high value chemicals.

Bioethanol pays full fuel duty (57.95 pence per litre) and VAT at 20%.

Biodiesel

Biodiesel achieves greenhouse gas savings of 87% – 92% compared to diesel. It is made from oil and fat based wastes and residues and oil crops. Waste-based raw feedstocks are preferable, as these give the best greenhouse gas saving and sustainability credentials.

Standard diesel sold at fuel forecourts contains around 7% biodiesel, and for this reason is known as B7. This fuel meets the EN590 standard for ultra low sulphur diesel. Higher blends (of 20%, 30% and even 100% can be used) and typically require some modification to the engine and fuel storage infrastructure. B100 (100% biodiesel) must comply with European Biodiesel Standard EN14214, whilst B20 and 30 must meet EN16709.
Some bus and truck manufacturers (OEMs) do not warranty the use of higher blends in their vehicles. This may be due to the required tests not having been done, rather than genuine concerns over engine impact.

Biodiesel is produced by reacting waste oil with methanol to produce Fatty Acid Methyl Ester. Glycerine is produced as a by-product.

RTFA members Argent Energy, Greenergy International Ltd and Olleco manufacture biodiesel and supply it in a variety of blends.

Biodiesel pays full fuel duty (57.95 pence per litre) and VAT at 20%.

Vivergo Fuels

Vivergo’s £350 million plant is one of Europe’s biggest bioethanol producers (capacity up to 420 million litres of bioethanol per year) and the UK’s largest single source supplier of animal feed.
