But range was a matter of battery capacity development, and hopes were high for a similar situation and development for aircraft.<\/p>\n<p>As is the case with almost every technological leap, the progression of alternative propulsion aircraft projects followed the Gartner Technology Hype curve (Figure 2).<\/p>\n<div id=\"attachment_48331\" style=\"width: 604px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/leehamnews.com\/wp-content\/uploads\/2025\/11\/Gartner-Hype-Curve-electric-aircraft.png\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-48331\" class=\"wp-image-48331 size-full\" src=\"https:\/\/leehamnews.com\/wp-content\/uploads\/2025\/11\/Gartner-Hype-Curve-electric-aircraft.png\" alt=\"\" width=\"594\" height=\"400\"\/><\/a><\/p>\n<p id=\"caption-attachment-48331\" class=\"wp-caption-text\">Figure 2.

In the 11 years since 2014, we\u2019ve had hundreds of entrepreneur-driven projects declare they will make environmentally friendly aircraft and airliners a reality.<\/p>\n<p>Nothing useful has come out of these projects, so today, we are passing the Trough of Disillusionment. Investors have stopped funding alternative propulsion startups as these have not produced useful air transport. The result is a mass death of projects, most silently, some more openly.<\/p>\n<p>The core of the remaining projects are run by experienced teams with solid aeronautical knowledge. These are now passing into the Slope of Enlightenment and will make real progress. Given that we are now entering a more productive phase, we take stock of these developments and their programs.<\/p>\n<p>To help the analysis, we use our Aircraft Performance and Cost Model, APCM, to show what the challenges are and how alternative propulsion can address these challenges.<\/p>\n<\/p><\/div>\n\n","protected":false},"excerpt":{"rendered":"<p>Subscription required By Bjorn Fehrm November 13, 2025, \u00a9 Leeham News: The interest for new and more environmentally friendly aircraft got underway in 2014, when Airbus flew the battery-electric E-fan demonstrator at the Farnborough Air Show in July, Figure 1.
