airports, Airlines and aircraft manufacturers are at the climate-pillory. In the discussion of the CO2-driven climate change refer to long-term self-commitments by 2050, emissions trading and voluntary offset programs. Because there is currently no Alternative to the Burning of large quantities of energy-rich kerosene.

This synthetic fuel can be recovered as Ethanol from biomass, or – with high energy costs – from the unlimited available hydrogen. A further Alternative reactors Solar.

A climate-neutral circuit

“We want to ensure that the air traffic-related CO2 emissions are reduced to zero. We know that this goal is only achievable if the kerosene is replaced by renewable fuels”, as stated in a recent Declaration of the German industry Association BDL.

“Power to X” is the formula: Under the use of large amounts of energy in water can be dissolved substance by electrolysis out of water, and then processed with ambient CO2 to fuel further. The X stands either for Gas or liquid fuels such as Diesel, gasoline or kerosene. If this is burned, it is put back CO2, which was deprived previously of the environment – a climate-neutral cycle.

heavy batteries

Electrically powered passenger aircraft holds, Lars Wagner, chief technology officer at Munich-based engine manufacturer MTU, for distant music of the future. “For 150 to 270 passengers, with today’s Battery technologies are not feasible,” he says. The batteries were much too heavy. Also, Wagner holds, therefore, the use of alternative fuels is the best way, because the current engines would not need to be rebuilt for it. If you create the fuel necessary for production of electricity is also sustainable, for example through solar power in the desert, one could improve the CO2 balance of conventional engines by 80 to 90 percent.

there is No production plant for Bio-Fuel

was Already in February 2008 completed a Jumbo of the company Virgin Atlantic is a first demonstration flight, in the case of the plant-produced Bio-Fuel and conventional kerosene mixed. Up to June 2019 followed according to the International Air Transport Association – the umbrella Association of all the airlines – more than 180’000 commercial transport flights. Nevertheless, it is still missing in the world production facilities.

the umbrella organisation of The airlines is to prefer air transport in the distribution of the “green” fuel compared to other transport sectors. In the case of the cars, the artificial fuels by environmentalists to be critical, because the energy losses in the production of hydrogen is expected to be very high. Far more efficient is to store the green electricity directly into the (battery)vehicles.

Lufthansa pröbelt also

The Swiss parent company Lufthansa trialled since 2011 on alternative fuels, which are mixed with the fossil kerosene beige. In the meantime, but it is far from clear that the cultivated areas of the world would not be enough competition for the production of food to satisfy the energy hunger of the growing Airline industry with Bio-Fuel.

4.2 million German tax money

This year, it was agreed, therefore, with the cooperation of the North German refinery in Heide, where, in the context of a 4.2 million euros in tax money funded research project in the future, wind power for the production of synthetic kerosene to be used.

A first pilot plant is scheduled to start by the end of 2023, and then five per cent of the demand at the airport Hamburg cover, says the refinery managing Director Jürgen Wollschläger. That would be a year or 20’000 tons of Eco-fuel.

Gigantic kerosene demand

The need is enormous: The international air travel has already been consumed, in 2010, approximately 142 million tons of conventional fuel. Experts of the civil aviation organization (Icao) assume that the demand could grow due to the continuous growth of air traffic by 2050, the six-fold, i.e., to about 860 million tonnes. Even with significant efficiency gains, there is a need of significantly more than 500 million tons, which can be according to the optimistic Icao forecast is only part synthetic, and climate-neutral production results for the year 2050 still.

Airbus has other ideas

The European aircraft manufacturer, Airbus is a part of electric drives or hydrogen fuel cells in the aircraft as a long-term Alternative.

The sustainably produced fuels would, however, urgently needed in order to achieve the short – and medium-term climate objectives of the air travel, the insured, the company has undertaken in the various programmes and initiatives for the Decarbonisation of the industry. Climate-neutral fuels would also be the charm of that with you today-built, conventional aircraft could be flown until the end of their often more-than-30-year cycle would.
