GULFSTREAM EXTENDS CONTRACT FOR LOW-CARBON SUSTAINABLE AVIATION FUEL
SAVANNAH, Georgia, September 14, 2020 — Gulfstream Aerospace Corp. today announced it has extended its contract with World Fuel Services to continue providing the business-jet manufacturer with a steady supply of sustainable aviation fuel (SAF) produced by World Energy.
Gulfstream President Mark Burns announced the deal today during the Virtual 2020 Business Aviation Sustainability Summit to discuss pathways to accelerate the market for SAF. Per gallon, SAF has at least a 60 percent smaller carbon footprint than conventional jet fuel on a lifecycle basis.
This contract extends Gulfstream’s original multiyear purchase agreement, which was the first of its kind in business aviation when it was signed in 2015. Since March 2016, Gulfstream has used SAF for its Savannah-based fleet, which comprises corporate, demonstration, completion, Customer Support and flight test aircraft. The company has made more than 650 flights with an SAF-JET A fuel blend, flying more than 1.3 million nautical miles and reducing carbon dioxide emissions by approximately 1,700 metric tons.
“This renewal marks another step in our ongoing commitment to promoting positive change in our industry,” said Mark Burns, president, Gulfstream. “Reducing our impact on the environment by using SAF is a move we all should consider making. Creating a sustainable future for aviation is a responsibility we share, and we appreciate the leadership, innovation and collaboration of World Energy in helping Gulfstream — and the industry at large — fulfill that responsibility.”
Gulfstream’s sustainability strategy helps support industry goals established by the National Business Aviation Association, the General Aviation Manufacturers Association and the International Business Aviation Council. The goals are a 50 percent reduction in carbon dioxide emissions by 2050 relative to 2005 levels; a 2 percent improvement in fuel-efficiency per year from 2010 to 2020; and carbon-neutral growth from 2020 onward.
The renewable fuel used by Gulfstream is produced by World Energy at its refinery in Paramount, California, from a feedstock of agricultural waste, fats and oils. Fuel and aviation services provider World Fuel Services manages the logistics, including distribution of SAF to Gulfstream on both U.S. coasts. In addition to using the 30/70 blend of low-carbon, drop-in SAF at its Savannah headquarters, Gulfstream makes it available for customers at its Van Nuys and Long Beach, California, service centers. SAF is the only fuel on-site at Gulfstream Long Beach, which also uses it for completions and delivery flights.
“The innovative partnership between Gulfstream and World Energy paved the way for a larger sustainability movement,” Burns said. “For almost a decade, we have leveraged our collaboration with World Energy to increase awareness and availability of SAF around the world. We look forward to continuing that work.”
Munich, 08 September 2020: Lilium, the Munich-based aviation company developing an all-electric, vertical take-off and landing aircraft for regional air mobility, has agreed with both Dusseldorf Airport and Cologne/Bonn Airport to explore how the two airports can become hubs within a regional air mobility network spanning North Rhine-Westphalia. Lilium plans to establish regional air mobility as a new mode of transportation, using its fully electric, 5-seater aircraft by 2025.
The announcement was made today in Dusseldorf in the presence of the Transportation Minister of North Rhine-Westphalia Hendrik Wüst. As the largest and most densely populated German state (18 million inhabitants), including ten cities with over 300,000 inhabitants, as well as more than 40 universities and colleges and four international trade fair locations, North Rhine-Westphalia is an ideal location for Lilium landing sites. The Rhine-Ruhr metropolitan area is the largest in Germany and the third largest in Europe. It now aims to become home to mobility in the third dimension.
North Rhine-Westphalia Transport Minister Hendrik Wüst explained: “What sounds like science fiction today may soon be reality. In the federal state with the highest mobility needs, smart ideas for better mobility are always welcome. We need all modes of transport in order to provide people with a convincingly diverse range of mobility options.“
He added: “North Rhine-Westphalia is a model region for the mobility of the future. We want digitally-networked mobility in North Rhine-Westphalia not only to be researched and developed, but also experienced as soon as possible. This is why we support and promote many future-oriented projects and research projects here in North-Rhine-Westphalia.”
As international traffic hubs with excellent connections to air, rail and road traffic, the two airports Cologne/Bonn and Dusseldorf are an ideal starting point for the development of networked mobility, which also includes air taxis.
“We are excited to bring our innovative service to North Rhine-Westphalia,” says Lilium COO Dr. Remo Gerber. “Cities such as Aachen, Bielefeld, Münster and Siegen will be directly connected to the region’s largest international airports within 30mins, providing emission-free, high-speed connectivity at an affordable price.”
Remo Gerber added: “North Rhine-Westphalia and its airports are ideal partners for us to implement this ambitious project of the future – we are grateful to receive this support from both the Ministry and our partners at the airports to implement our vision”.
LG Chem has succeeded in flying at the highest altitude with a lithium-sulfur battery for the first time in Korea

■ CTO / President Kisu Ro,
“LG Chem will consolidate its position as the leading firm in the global battery market by focusing on research and development of the next generation battery sector.”
LG Chem has succeeded in flight testing of an unmanned vehicle at the highest altitude using the next generation battery for the first time in Korea.
In respect of this LG Chem announced that a high-altitude long-endurance solar-powered unmanned vehicle (EAV-3) developed by Korea Aerospace Research Institute has successfully finished flight testing in the environment of the stratosphere using its lithium-sulfur battery, on 10.
* Stratosphere: it is an atmospheric layer ranging from 12-50km altitude between the troposphere (the ground – 12km) and the mesosphere (50-80km).
EAV-3 is a small aircraft which can fly in the stratospheric altitude of 12km or higher for a long period of time using solar energy and batteries. It charges energy using a solar cell placed on the top of the wing. During the daytime, it flies utilizing a solar cell and battery power as a source of energy and during the night time, it utilizes battery power charged during the day time. It has wings of 20m long and a body of 9m long.
On 30 August, LG Chem loaded a lithium-sulfur battery on EAV-3 at the Aviation Center of Korea Aerospace Research Institute in Goheung and conducted flight testing approximately for 13 hours from 08:36AM to 09:47PM. LG Chem is the first company in Korea which conducted flight testing using a lithium-sulfur battery.
Especially, EAV-3 flew in the altitude of 22kms, which is unprecedented for a domestic unmanned aircraft, and achieved a new record of flying at the highest attitude in the stratosphere in Korea. Also, it flew for 7 hours out of a total of 13 flight hours with a stable output in the stratospheric altitude of 12-22km where a general aircraft cannot fly.
This fight testing is highly significant as it confirmed a stable charge/discharge function of a lithium-sulfur battery, the next generation battery in the extreme environment of the stratosphere with a low temperature of 70 degrees below zero and atmospheric pressure of 1/25 of one at ground level, which is close to a vacuum state.
A lithium-sulfur battery is one of the next generation batteries which will replace a lithium-ion battery, and its energy density is 1.5 times higher than the existing lithium-ion battery, which has a high energy density per weight, as it uses lightweight materials such as sulfur and carbon compounds for anode materials and lithium metal, etc. for cathode materials. The merit of the lithium-sulfur battery is that it is lighter and more competitive in terms of price compared to the existing lithium-ion battery as it does not use rare metals.
Also, it is considered as a key component that would determine the function of the future transportation such as electronic cars as well as long-endurance drones and personal aircraft, etc. and many countries in the world are competing intensely for the development of the same.
For a year and 6 months, LG Chem Future Technology Research Center’s Innovative Battery Project Team has conducted research on the development of a lithium-sulfur battery in the low temperature and atmospheric pressure by creating the extreme environment similar to the stratosphere, and could successfully complete this flight testing based on such research.
LG Chem plans to demonstrate a long-endurance flight that lasts more than a number of days by producing additional trial products of lithium-sulfur batteries in the future. Moreover, it plans to mass-produce a lithium-sulfur battery that has an energy density more than twice that of the present lithium-ion battery after 2025.
Kisu Ro, the CTO/President of LG Chem, mentioned “LG Chem has proved that it has the world’s best technology in the sector of the next generation battery with a high energy density from this flight testing” and “it will consolidate its position as the leading firm in the global battery market by focusing on research and development of the next generation battery sector”.
