Sustainability is a key consideration in the aviation industry, according to aPictet Asset Management webinar, “The Sun Shines in the New Dawn of Aviation Technology,” held yesterday. I investigated.
Hydrogen fuel cells are a sustainable option, such as ultralight materials and synthetic fuels, while significantly reducing greenhouse gas emissions. In addition, other options for engine and battery-powered short-haul flights are being considered.
Andre Borschberg, co-founder and chairman of Swiss technology company H55, said: about.
“We will either modify these planes and clean them up, or build new planes.”
While there are many solutions to improve aircraft efficiency, hydrogen as a fuel is key. Liquid hydrogen must be produced at extremely low temperatures and distributed and stored as is. As a result, the use of liquid hydrogen will soon or become uncommon.
Rolls-Royce Electrical Customer Director Matheu Parr said:
“This is an ongoing deal in the industry. In Advanced Air Mobility, we are excited about the use of fuel cells in our domestic aircraft.”
There is currently no liquid hydrogen available in Switzerland, but it will be available in the future. Surveys, studies, and tests have demonstrated this appeal.
It is expected that the number of gas turbine systems will increase and the efficiency of gas turbine systems will increase.
Parr said: We are looking at ways to improve the efficiency of gas turbine systems through increased electrification.
“If you look at an aircraft flying across the Atlantic, you can improve efficiency by 2% to 4% by incorporating more electrical technology. Over the past 30 years, we have improved our gas turbine systems by 15%. ”
There are many solutions to replace oil, such as electric motors, battery systems, fuel cells and hybrid solutions, but battery and hydrogen options are not as energy dense as traditional options.
For products to be developed, it is important that the aviation industry continues to encourage technology programs and promote sustainability agendas.
Opportunities in this market are increasing as current solutions such as combustion engines are seen as inefficient. No matter which engine you use, the engine requires maintenance, but electric motors require less maintenance because they have less friction.
H55 and Rolls-Royce Electrical provide solutions that enable aircraft manufacturers to develop cleaner aircraft. Various projects are underway to spread the risk.
H55’s products include lightweight, modular energy storage and management systems, and Rolls-Royce Electrical’s focus is on propulsion and energy systems for the urban and regional air mobility market.
The aviation industry is becoming more receptive to change to address sustainability, fueled by expectations of government support on the regulatory side. The frameworks used to certify aircraft are evolving in line with sustainability.
The level of sustainable aviation fuel available is another aspect that government support could impact.
