Exploring Tomorrow’s Aviation with New Energiess

In the quest for sustainable transportation, the aviation industry stands at a crossroads. With increasing environmental concerns and a growing demand for air travel, the need for cleaner, more efficient energy sources has never been more pressing.

Here, we delve into some of the most promising new energies that hold the potential to transform tomorrow’s aviation landscape;

Biofuels

Biofuels have emerged as one of the leading contenders for reducing aviation’s carbon footprint. These fuels, derived from renewable biomass sources such as algae, waste oils, and plant matter, offer a promising alternative to traditional jet fuels. Unlike fossil fuels, biofuels produce fewer emissions and can be used in existing aircraft engines with minimal modifications. Airlines like Turkish Airlines, United, KLM have already conducted successful flights using biofuels, demonstrating their viability as a sustainable aviation solution.

Hydrogen

Hydrogen has long been touted as a clean and abundant energy source with the potential to power various modes of transportation, including aircraft. Hydrogen fuel cells generate electricity by combining hydrogen with oxygen, producing only water vapor as a byproduct. While hydrogen-powered aircraft are still in the early stages of development, companies like ZeroAvia and Airbus are actively working on prototypes and conducting feasibility studies. With advancements in hydrogen storage and infrastructure, hydrogen-powered aviation could become a reality in the coming decades.

Electric Propulsion

Electric propulsion systems offer another promising pathway towards sustainable aviation. By replacing traditional gas turbines with electric motors powered by batteries or fuel cells, electric aircraft can significantly reduce emissions and noise pollution. While electric propulsion is currently limited to smaller aircraft for short-haul flights, ongoing research and development aim to scale up the technology for larger commercial planes. Companies like Lilium and Eviation are leading the charge in electric aviation, with plans to bring emission-free air travel to the masses.

Solar Power

Solar power holds immense potential for extending the range and endurance of electric aircraft. Solar panels installed on the wings or fuselage of an aircraft can capture sunlight and convert it into electricity, supplementing the onboard power supply and reducing the reliance on traditional energy sources. While solar-powered aircraft are primarily used for experimental purposes and unmanned aerial vehicles (UAVs) at present, advancements in solar cell efficiency and lightweight materials could pave the way for commercial solar-electric aircraft in the future.

Hybrid Solutions

Hybrid propulsion systems, combining multiple energy sources such as fossil fuels, biofuels, batteries, and fuel cells, offer a flexible approach to sustainable aviation. By leveraging the strengths of each energy source, hybrid aircraft can optimize performance, range, and emissions according to the specific requirements of the mission. This hybridization approach allows for gradual transitions towards greener technologies while ensuring compatibility with existing infrastructure and regulatory frameworks.

As the aviation industry strives to decarbonize and mitigate its environmental impact, the adoption of new energies is essential for driving innovation and ushering in a new era of sustainable air travel. While significant challenges remain, including technological barriers, regulatory hurdles, and economic viability, the collective efforts of stakeholders across the aviation ecosystem are propelling us towards a future where flying is not only faster and safer but also cleaner and greener. By embracing new energies and fostering collaboration, we can soar to new heights while preserving the planet for generations to come.

New Aviation Energies at Turkish Airlines

Turkish Airlines, the flag carrier airline of the Republic of Türkiye, has taken its place among the largest airline companies in the world with its rapid growth trend since its foundation in 1933, with the objective of carrying out domestic and international passenger and cargo air transportation activities. As the airline that flies to more countries than any other airline in the world, Turkish Airlines currently has a network of 370 destinations in 130 countries with its 454 aircraft fleet.

This huge network and operations make efficient energy practices inevitable. The company is at the forefront of embracing new energies to propel the aviation industry towards sustainability. With a commitment to reducing carbon emissions and embracing cleaner technologies, the airline is actively exploring innovative solutions.

Turkish Airlines adopts the principles of using energy with maximum efficiency, reducing the use of natural resources and sustainable development. In this context, Turkish Airlines declares its Energy Policy to bring together its employees, customers, suppliers, subcontractors, affiliates, all business partners, and shareholders for the same purpose.

According to IATA projections, the aviation sector is expected to have a significant share in human-induced greenhouse gas emissions in the future. Accordingly, the sector aims to reach a net zero emission level in 2050 in line with the 1.5ºC target of the Paris Agreement. To this end, IATA emphasises sustainable aviation fuel (SAF), new aircraft technologies, use of electricity and hydrogen energy, offsetting carbon emissions and carbon capture practices.

Turkish Airlines shapes its climate action efforts in this direction. Fuel efficiency applications are a prominent field of study in terms of emission reduction and cost savings. While adding new aircraft to its fleet, Turkish Airlines also favours models with high fuel efficiency and low emission levels. In addition, the acquisition of efficient aircraft models with high fuel efficiency to the fleet provides savings in maintenance, repair and operating costs. On the other hand, the fact that the interior design and features of new generation aircraft respond more accurately to changing passenger expectations has a positive impact on customer satisfaction and loyalty.

From biofuels derived from renewable sources to electric propulsion systems, Turkish Airlines is also exploring a range of alternatives to traditional jet fuels. These technologies not only reduce environmental impact but also pave the way for more efficient and eco-friendly air travel.

By investing in research, development, and partnerships, Turkish Airlines is positioning itself as a leader in the adoption of new aviation energies. Through these efforts, the airline aims to create a greener future for aviation while continuing to provide exceptional service to passengers worldwide.

Turkiye’s national flag carrier has started using sustainable aviation fuel on its flights to help reduce its carbon footprint.Turkish Airlines’ first flight using aviation fuel obtained from sustainable sources departed from Istanbul Airport on February 2, 2022 for the Charles De Gaulle Airport in Paris.

While sustainable fuel, which reduces emissions by 87%, has been used for one day a week on the chosen route, the airline is currently using it on different routes on a wider scale.

Sourced from oil refining company Neste, the environmentally friendly fuel is stored by Turkish Airlines subsidiary Turkish Fuel Services (TFS) to be loaded onto aircraft after getting blended with jet fuel.

As Turkish Airlines is making waves in the national and international arena with its sustainability-focused activities and awards, flag carrier was awarded the “Airline Sustainability Innovation of the Year” award by CAPA – Centre for Aviation for its innovative efforts within the scope of sustainability.

The global carrier, which puts sustainability at the center of its business model, won this award within the scope of sustainable innovation with the “Microalgae Based Sustainable Bio-Jet Fuel Project (MICRO-JET)”, in which it worked closely with scientists to develop the world’s first carbon negative sustainable aviation fuel (SAF).

Within the scope of the “Microalgae Based Sustainable Bio-Jet Fuel Project (MICRO-JET)”, jointly carried out with Boğaziçi University, it is aimed to produce biofuels from microalgae using hydro-processed fatty acids and hydrothermal liquefaction methods.

Once the project is completed, the first carbon-negative integrated bio refinery of Turkey and Europe will begin service.

Turkish Airlines also implemented over 100 operational optimization projects since 2008 to lower its carbon footprint; saving  57,581 tons of fuel, offsetting 6,619 tons and preventing nearly 181,379 tons of carbon dioxide from being released into the atmosphere in 2022.
