There are three big emissions sources that are really hard to electrify: 1. Long haul trucking 2. Aviation 3. Shipping The batteries required to power the above type of transport plus cargo load, would just be too heavy and take up too much space, because batteries have way lower energy density compared to fuel. (Source: https://lnkd.in/gFhz9r62) Hydrogen will be an indispensable part of the solution needed to achieve decarbonization targets while powering trucks, planes and ships. What are your thoughts?

What do you know about the fuel sources powering sustainable aircraft?

I was just talking yesterday about Scottish Outer Isles sustainable marine connectivity. May I suggest that Central & Devolved Government should study and embrace Rolls Royce's innovative, carbon efficient, marine propulsion solution. This will encourage zero carbon, all battery propulsion systems for smaller craft. Then what we need to focus on is building port-side electrical infrastructure plus beefing up the local supply network at LV-substation. At night, when ferry ops are suspended, these vessels will create a virtual portside power hub thru V2X, delivering power network distribution resilience. [With thanks to RR] "Powered by [RR] mtu Hybrid Propulsion Packs, the Vittorio Morace ferry provides a quiet, emissions free, purely electric mode of transport around ports. When it hits the open ocean, switching to hybrid mode enables the combustion engines to reach top speeds while simultaneously driving the electric machines to recharge the batteries and provide onboard electricity. It’s the first of nine ships with hybrid power that was delivered to the Italian shipping company @Liberty Lines. The sister ships will follow until the first half of 2026." https://ow.ly/RQ1z50Se2hK #hybridpower #mtusolutions #ferrypower #V2X #lowcarbonmarinepower #guptasmartenergy #innovateuk #innovationnorway #ukgov #scottishgov #scottishouterislands

The aviation industry is soaring towards a low-carbon future, embracing innovative technologies to meet the net-zero carbon emissions target by 2050. While there, of course, are some uncertainties overall prospects are truly bright! 🔍 Increasing Carbon Emissions, Mounting Urgency  The aviation industry, responsible for 3.5% of human-caused carbon emissions today, faces urgent calls to decarbonize. With 25% emissions projected by midcentury, the race is on to explore solutions such as Sustainable Aviation Fuel (SAF), electrified fuels (PtL), battery-electric aircraft, and hydrogen fuel cell aircraft. 💡 Sustainable Aviation Fuel (SAF)  Blending SAF into jet fuel offers a promising solution with minimal infrastructure changes. However, challenges like limited supplies and sustainability concerns need addressing. The U.S. government's $4.3 billion investment aims to scale up SAF production. 🔄 Power to Liquid and e-Fuels  Synthetic hydrocarbons present a cost-effective alternative to SAF. Power-to-Liquid (PtL) methods, including hydrogen conversion, show potential for widespread adoption, contributing significantly to decarbonization goals. 🏗️ Infrastructure Planning for Carbon Neutral Flights  Airports play a crucial role in supporting diverse decarbonization strategies.

Why Sustainable Aviation Fuel (SAF) is crucial for the aviation industry to achieve net zero emissions: - Drop-in fuel compatibility is key: Given the 20-30 year lifespan of commercial airliners, the fuel used today will impact emissions well into 2050. - Long-term challenges of battery and hydrogen solutions: While electric and hydrogen-powered aircraft show promise, they present significant obstacles in the medium term. Electric flight is limited by battery energy density, and hydrogen faces challenges related to storage, infrastructure, and aircraft fuel tank modifications.

Interesting article from Yale School of the Environment. Flying Green: The Pursuit of Carbon-Neutral Aviation Revs Up To eliminate global aviation’s sizable carbon footprint, researchers are working on a range of alternatives to fossil jet fuel. Recent test flights powered only by hydrogen or biofuels have been successful, but steep challenges remain before aviation can become carbon-free. #sustainableaviation #carbonemissions https://lnkd.in/eTBG53Hs

The aviation industry’s shift towards #zeroemission solutions has been driven by heightened concerns about greenhouse gas emissions. With air travel demand rebounding since the pandemic, there’s a pressing need to address the industry’s significant contribution to global greenhouse gas emissions.   Jonathan Douglas-Smith, Head of Sales for our aerospace products at Intelligent Energy, discusses the readiness of the UK for fuel cell aircraft.   "Hydrogen fuel cells hold a strong position as we journey towards zero-emission aviation, promising not only environmental advantages against fossil fuels, but also the ability to transport significant numbers of passengers across meaningful distances compared to batteries."

✈️“Sustainable” or synthetic Aviation Fuel (SAF): The future of flight needs Green Hydrogen”✈️ Here’s a bold idea: To replace fossil kerosene, Boeing is betting big on “Non Fossil Kerosene” or so-called “Sustainable” Aviation Fuels (SAF). But there’s a key ingredient needed to scale SAF: Green Hydrogen. Why? Because the best way to create sustainable feedstock for SAF is through Power-to-Liquid (#PtL) technology, which relies on green hydrogen. But here’s the challenge: Today, 98% of hydrogen isn’t green. It’s made using fossil fuels, meaning it can worsen the problem instead of solving it. Boeing is aware of these hurdles. They’ve been studying sustainable propulsion for decades and are actively working to integrate green hydrogen and SAF into the future of aviation. The vision? A world where flying doesn’t cost the earth. Here’s my question to you: ✈️ Do you think green hydrogen is the key to scaling SAF? Or is there another way? <source https://lnkd.in/eumxy8v2> #SAF #GreenHydrogen #SustainableAviation

Always appreciative of the thoughts of my colleague Jim Hileman, formerly chief scientist at Federal Aviation Administration and now at Boeing! See synopsis of his great talk on driving down the climate impact of aviation sector. Backing up a step, when we talk about RD&D needs for aviation in a decarbonizing sector, it’s crucially important to differentiate between four different options which can be organized in a 2x2 matrix: Matrix axis 1: (1) economy wide decarbonization (where different sectors, such as ground transport, buildings, industry, etc.) contribute in a coordinated way achieving the macro goal of zeroing out our climate impacts, and (2) sector by sector decarbonization, where each sector individually zeroes out its contributions. Matrix axis 2: (A) Net zero carbon emissions (ie, we continue to use renewable hydrocarbons, like SAF) (B) zero emission- ie no CO2 emissions at all Your preferred option of these four depends upon what metric you are trying to optimize. If your metric is “eliminate our CO2 emissions at least overall cost”, then option 1A is far away what you want to do. I bring this up because well meaning efforts to make aviation sector net zero or zero CO2 emissions sound good on paper, but they are also more expensive. If your goal is to minimize cost, we are much better to let aviation be a positive CO2 emitter, and use those dollars on stationary negative emissions technologies

International Air Transport Association (IATA) with its partners released the "Aviation Net Zero CO2 Transition Pathways Comparative Review". This publication compares 14 leading net zero CO2 transition roadmaps for aviation and attempts to better understand the key similarities and differences between the various roadmaps, and their visions for achieving net zero carbon emissions for aviation by 2050. The report compares the selected roadmaps in terms of their scope, key input assumptions, modeled aviation energy demand, respective CO2 emissions, and the emissions reduction potential of each mitigation lever (new aircraft technologies, zero-carbon fuels, SAF, and operational improvements). Highlights: - All roadmaps assume that Sustainable Aviation Fuels (SAF) will be responsible for the greatest amount of CO2 reductions by 2050. The role of SAF varies from 24%-70% (with a median value of 53%). - Technology and operational efficiency improvements are expected to together contribute to about 30% of the emissions reduction in 2050. - The emissions savings by hydrogen and battery-powered aircraft vary greatly. - To achieve net zero CO2 emissions in 2050, the aviation sector will need help from market-based measures and carbon removals to address the residual emissions in 2050. - Even if carbon removal technologies are considered an out-of-sector mitigation measure, it is still both urgent and critical to develop these technologies as CO2 will be needed as feedstock for producing power-to-liquid (PtL) fuels.
