There is value in reading stuff that you disagree with, it provokes your mind to sharpen and formulate your own views precisely. This report provides some fertile ground. “[R]eaching the 2050 targets will require new vessels burning new sustainable fuels.” This is an example of fuel-centric thinking, disregarding possible innovation away from fuels 1.     Wind propulsion is the obvious example for cargo transport, especially on predictable routes 2.     Plug-in electric vessels probably won’t cause oceans, but are an increasingly viable alternative for ferries 3.     We’ve seen that solar yachts are viable in an upscale segment, so it’s a matter of time and cost-curve dynamics until this technology is also applicable to specific market niches. While it may be difficult to replace fuels all together I believe that some market segments offer good opportunities away from them.   … this post started becoming too long, to be continued… Full report: https://lnkd.in/gFtYUf5j

Aviation Energy and Decarbonization - on YouTube The Plenary Lecture on Aviation Energy and Decarbonization that I gave to the ICAS meeting on September 9 is now available online - https://lnkd.in/eN-N9wam. As I posted last week, I had the honor of giving a plenary lecture to the 34th Congress of the International Council of the Aeronautical Sciences (ICAS) in Florence, Italy. In it, I used the Boeing Cascade Climate Impact Model (https://lnkd.in/efvvBdMM) to examine different paths aviation could take to get to net zero. I start the lecture with a summary of the challenges facing aviation in terms of reducing climate impacts. The aviation industry is utilizing a decarbonization strategy based on better airplanes, more efficient operations, sustainable energy, and offsets and removals. The majority of the lecture is focused on sustainable energy as efficiency alone cannot get us to zero. This is in spite of the fact that today's fleet of aircraft is as efficient as a modern hybrid electric car (58 passenger-miles per gallon in 2019), and we are doing much to get to 100 passenger-miles per gallon by 2050. The portion of the lecture on sustainable energy starts with conventional jet fuel as it is a critical component of the safe, reliable, and efficient global air transport system we have today. I then discuss the promise of Sustainable Aviation Fuels (SAF) along with the challenges we are facing in scaling them up. When thinking about SAF, it is important to consider the different types of SAF. I categorize SAF based on four broad feedstock types to better understand where we are today and the potential to achieve substantial growth in the future. I also discuss efforts in Boeing to enable the use of 100% SAF and the importance of aromatic compounds. I then consider electricity and hydrogen as aviation fuels. Batteries could power aviation over relatively short distances thus helping to decarbonize urban and regional aviation. Hydrogen has long been of interest as an aviation fuel with efforts focused on overcoming challenges from the aircraft design perspective. In this lecture, I discuss some of the challenges that need to be overcome from infrastructure and geopolitical perspectives. I conclude the lecture with the work we are doing in Boeing to address the climate impacts of persistent contrails. The key message in my lecture is that aviation decarbonization requires us to solve a system of systems problem that goes well beyond aerospace. It's a challenging problem that requires experts coming together from a wide range of disciplines covering aerospace, energy, infrastructure, policy, among many others. I also used the lecture as an opportunity to highlight the future direction of Cascade. I would also like to thank the incredible team that helped assemble the lecture - Neil Titchener, Bridget Boland, Jamie Abel, Addison Salzman, and Ellen E. Curious to hear what others think.

This is a great lecture by Jim Hileman of Boeing at the ICAS conference. However, the battery electric pathway is far more attractive than shown in this presentation (see from minute 36 onwards). This lecture suggests that with current technology (200-300 Wh/kg energy density) the maximum battery electric range would be around 100 NM. This is based on incorrect assumptions, which are pretty persistent in the aeronautical industry. The line of reasoning is roughly like this: a battery electric aircraft would be for short ranges, so current short range (turboprop) aircraft are the reference. These aircraft have an empty weight ratio of at least 55% and carry 20+% payload, so the maximum energy mass fraction (energy mass divided by maximum take off mass) is around 20-25%. The Lift-Drag ratio of these aircraft is around 16-17 and with these inputs you calculate the Breguet range, subtract the range required for reserves and you get to the ~100 NM. However, there is another design space, much more inspired by first generation jets like the Boeing 707 and Douglas DC8, which enable you to reach far higher energy mass fractions and much higher Lift-Drag ratios. This does NOT require any new lightweight technology or advanced aerodynamics. It is purely driven by how the energy weight fraction and lift-drag ratio scale with different tube & wing configurations. Our research, in collaboration with the Delft University of Technology faculty of Aerospace Engineering, shows that when batteries reach a usable pack level energy density of 300 Wh/kg, the theoretical range can be as high as over 1000 km (check our papers via the link below). This is the basis for our E9X design, which can carry 90 pax over initially 800 km, growing to 1000 km, fully battery electric. Reserves will be covered by a turbine-based Reserve Energy System. This will make short range aviation fully sustainable, addressing both CO2 and non CO2 emissions. We will share further details on the total ecological footprint during Climate Week this week in NYC. Spoiler alert: the conclusion is that on distances where you can fly battery electric, you should. In summary, I believe this lecture very well highlights the enormous challenge of decarbonizing aviation. This requires us as an industry to work together and use every available technology pathway. Battery-electric for sure is one of these pathways and we at Elysian Aircraft are committed to do so.

🌍 Breaking Down the Three Scopes of Carbon Emissions 🌿 When it comes to calculating a company’s carbon footprint, the framework of the three scopes offers a clear way to understand and act on emissions: 1️⃣ Scope 1: Direct emissions from sources the company owns or controls, like fuel used in vehicles or onsite energy production. 2️⃣ Scope 2: Indirect emissions from purchased energy, such as electricity, heating, or cooling. 3️⃣ Scope 3: All other indirect emissions throughout the value chain, from the production of raw materials to the disposal of products. Addressing emissions across these three scopes is essential for meaningful progress toward sustainability and reducing global carbon impact. The more comprehensive our understanding, the more impactful our solutions can be. 🌱 Let’s continue the conversation on building a greener future! 💡
