Xcalibur Multiphysics and MONTE Announce a Partnership to Retrofit Aircraft to Zero Emission Propulsion

MONTE - Xcalibur MPH

Xcalibur Multiphysics is pleased to announce an exclusive partnership with MONTE Aircraft Leasing Limited – an alternative asset-based management company focused on the leasing and financing of zero-emission aircraft and the retro-fitting of existing aircraft with electric, hybrid or hydrogen propulsion technologies. Xcalibur and MONTE will join forces to provide a conversion of Xcalibur’s fleet of aircraft to electric, hybrid or hydrogen versions.

The aircraft conversion will consist initially of, amongst other characteristics, the integration of an electric, hybrid or hydrogen propulsion system in the Cessna Grand Caravan 208B aircraft in Xcalibur’s fleet to convert them into low-emission aircraft. In future, other aircraft in Xcalibur’s fleet (Air Tractor AT502 & AT802 and Twin Otter) will be also considered for conversion.

Together, Xcalibur Multiphysics and MONTE will strive to identify the most suitable zero-emission propulsion technology for their operations. Once the technology is approved and certified, the appropriate conversions will take place.

MONTE is a clean technology business focused on retrofitting existing aircraft with zero emission propulsion systems and acquiring and financing new, zero emission aircraft as they are produced and certified for use.

Xcalibur Multiphysics is a world leader in Multiphysics. It owns more than 25 specialised aircraft with 85 geophysical systems and has executed over 1,000 projects globally. Throughout its 100 years of experience, and 13 office locations in all continents, Xcalibur plans to grow its aircraft fleet up to 40 aircraft within 2 years. Xcalibur has acquired more than 50 million linear kilometers of collected data. The multinational Group continues to execute projects with safety, sustainability, technological innovation, operational excellence, and cost leadership at the center of its core values.

Environmental Sustainability is a key component in Xcalibur’s ESG strategy, and this agreement is another great step in its path to become a reference player in the natural resources and energy transition map, while promoting the highest standards of Health, Safety and Environment protection and operates according to the world’s best HSE practices.


We are excited to announce our partnership with Xcalibur Multiphysics and to support the transition of their fleet to a more sustainable future. We believe the mission profile and route network of Xcalibur’s fleet to be well suited to zero emission propulsion technologies, and look forward to working with the entire Xcalibur team on this exciting and necessary transition. This partnership is another important step in our journey to become one of the world’s first zero-emission aircraft lessors, as we look to finance zero emission solutions for turboprop operators around the world.

Timothy Eyre, Investment Director, MONTE Aircraft Leasing Limited.


“We are delighted to cooperate with MONTE in this necessary journey towards ZERO emissions plan. Today more than ever we must actively participate in this energy transition process where Xcalibur wants to be a key player from its leadership position in the airborne Multiphysics market. With this partnership cooperation and development agreement with MONTE, Xcalibur shows again its commitment to The Sustainable Development Goals 2030 and beyond.
