Jet Zero consultation – what it says on “sustainable aviation fuels” (spoiler…crazy over-optimism)

The DfT’s consultation on reducing aviation carbon emissions, “Jet Zero” places a lot of faith in finding novel, low carbon fuels, so people can continue to fly as much as they want. These are called “Sustainable Aviation Fuels” (SAF). The consultation says SAF “could play a key role in decarbonising aviation, whilst also representing an industrial leadership opportunity for the UK.” The economic opportunity aspect, and producing jobs, is key for the DfT.  They say “Many experts view SAF as the only alternative for long-haul flights up to 2050, which are the flights with the biggest climate impact.” The DfT is hoping SAF could “result in over 70% CO2 emissions saving on a lifecycle basis and could deliver net zero emissions with the addition of greenhouse gas removal technologies.” SAF would either be biogenic, non-biogenic (from wastes) or made using zero-carbon electricity.  There are huge problems, glossed over by the consultation. A key problem is that “there is currently no comprehensive global regulatory standard for SAF sustainability. The UK is therefore active at ICAO in negotiating for a full set of sustainability criteria for SAF.” The DfT “will shortly consult on a UK SAF mandate setting out our level of ambition for future SAF uptake.” .Tweet   The Jet Zero consultation “Achieving net zero aviation by 2050” From:   Department for TransportPublished14 July 2021 https://www.gov.uk/government/consultations/achieving-net-zero-aviation-by-2050 Some extracts of the text relating to Sustainable Aviation Fuels (SAF) P 26 – 29 Sustainable aviation fuels could play a key role in decarbonising aviation, whilst also representing an industrial leadership opportunity for the UK. 3.13 As well as improving the efficiency of aircraft, we need to reduce the climate impact of the fuels that they use. 3.14 SAF are a ‘drop in’ option, meaning they can be blended into fossil-based aviation fuel and used in existing aircraft without modification and therefore could deliver both medium- and long-term CO2 emissions savings. Many experts view SAF as the only alternative for longhaul flights up to 2050, which are the flights with the biggest climate impact; it is estimated that flights greater than 5,000km (equivalent to a flight from London to Bahrain), which make up just 10% of overall flights, are responsible for over 60% of UK aviation emissions.27 3.15 When compared to conventional fossil aviation fuel, SAF produced from feedstocks with strong sustainability credentials can result in over 70% CO2 emissions saving on a lifecycle basis28 and could deliver net zero emissions with the addition of greenhouse gas removal technologies. Most SAF also emit less soot and particulate matter compared with conventional fossil jet fuel which is expected to reduce non-CO2 climate impacts. What are SAF? “SAF” are low carbon alternatives to conventional, fossil-derived, aviation fuel – ‘drop in equivalents’ that present similar characteristics to conventional jet fuel. Generally, SAFcan be produced from three types of feedstock: • Biomass: this includes biogenic waste, e.g. used cooking oil.• Non-biogenic waste: e.g. unrecyclable plastics or waste fossil gases from industry.• CO2 + green hydrogen: zero-carbon electricity is used to produce hydrogen through water electrolysis; hydrogen then reacts with CO2 captured from the air or waste industrial exhaust streams to produce a synthetic fuel. This process is known as Power-to-liquid (PtL). …. The benefits of sustainable aviation fuel 29 A UK SAF industry could generate between £700m–£1.6bn in Gross Value Added (GVA) per year. Creating between 5,000–11,000 green jobs. Helping the UK to ‘level up’ and not rely on oil imports, with production facilities across the whole of the UK. —- The Jet Zero Council SAF Delivery Group has been set up for government and industry to work together to establish UK SAF production facilities and accelerate the delivery of the fuel to market. It is focused on the development of a UK SAF mandate, the commercialisation of the sector, and the technologies and feedstocks that the UK should prioritise. 3.17 SAF supply is already rewarded through the Renewable Transport Fuel Obligation (RTFO) which provides tradeable certificates for every litre of certain sustainable fuels used for aviation. The Government has also provided grant funding to businesses through our Advanced Biofuel Demonstration Competition (2014) and Future Fuels for Flight and Freight Competition (2017), putting the UK in a strong position to develop advanced fuels capable of decarbonising harder-to-decarbonise sectors. We are now building on this ambition through the Green Fuels, Green Skies competition which is providing £15m in 2021-22 to support the early development of first-of-a-kind commercial SAF plants in the UK. 3.18 Our strategy will build on this commitment. We are continuing to develop plans for a SAF clearing house and will shortly consult on a UK SAF blending mandate to kickstart the market which could enable greater SAF uptake than is within the CCC’s Balanced Pathway. We are keen to maximise the e
