H2Fly's Breakthrough Flight Demonstration Bolsters the Case for Liquid Hydrogen Propulsion

Hydrogen propulsion pioneer H2Fly’s efforts to bring the technology to the air transport sector were energized by the breakthrough flight of its HY4 demonstrator aircraft at Maribor Airport in Slovenia last week. Co-founder and CEO Josef Kallo was visibly pleased when talking to media on the sidelines of the event, describing it as “a major milestone” and “world’s first.”

Scotland's Loganair Lays Out Plans To Decarbonize Regional Air Services

Scottish regional airline Loganair is evaluating options to bring new electric aircraft into its fleet. The carrier's head of sustainability says it needs to do more work to ensure that the business case for decarbonization would stack up, with operating economics that would support affordable airfares.

Bristow and Volocopter Partner to Bring eVTOL Air Services to the U.S. and UK

Bristow Helicopters has placed a firm order for two Volocopter VoloCity eVTOL aircraft with the option to purchase up to 78 additional vehicles in the future. The two companies have also signed a joint development agreement in which they pledged to collaborate on several aspects of the urban air mobility ecosystem, including infrastructure and regulations.

SkyDrive and JAXA Partner on eVTOL Noise Research

SkyDrive is embarking on a joint research project with the Japan Aerospace Exploration Agency (JAXA) to study ways to estimate, evaluate, and reduce the noise produced by eVTOL aircraft. The Tokyo-based start-up, which is developing a three-seat eVTOL air taxi, has been using JAXA’s largest wind tunnel since 2021 to evaluate the aerodynamics of its rotors. Now SkyDrive will employ the wind tunnel facility and JAXA's new noise-analysis technology to pinpoint and reduce the sources of noise emitted by the rotors.

Korean Lessor Solyu Orders 25 Eviation Alice Aircraft

South Korean leasing company Solyu has signed a letter of intent with Eviation covering 25 Alice all-electric commuter aircraft. The LOI, which also calls for an option on another 25 aircraft, marks the first such “order” for the nine-seat Alice since Eviation outsourced its design work to Seattle-based engineering firm TLG Aerospace.

Airbus, Rolls-Royce, EasyJet Headline Formation of UK Hydrogen Alliance

A group of leading companies in the UK aviation and renewable energy sectors has established the Hydrogen in Aviation (HIA) alliance to accelerate the delivery of zero-carbon aviation, the companies said Tuesday. HIA, whose partners also include Airbus, Rolls-Royce, EasyJet, Ørsted, GKN Aerospace, and Bristol Airport, said decarbonization efforts involving the direct use of hydrogen should assume more urgency at a time sustainable aviation fuel and batteries have drawn so much of the sector’s attention.
