  • Universal Hydrogen, pioneer of hydrogen-powered flight, goes bust

    By  Dominic Gates Seattle Times aerospace reporter Universal Hydrogen, the pioneering company that flew a partially hydrogen-powered flight out of Moses Lake in March last year, has burned through the $100 million it raised from investors and gone bust. The company was one of a few aiming to replace fossil-fuel powered flight with more sustainable,

    Aircraft Size Comparison – A320, A321, and Transcontinental/Transatlantic H2 Aircraft

    The image compares four narrow-body aircraft configurations: the conventional Airbus A320 and A321, alongside two hydrogen-powered concept variants labeled 'Transcontinental H2' and 'Transatlantic H2.' The H2 variants show large cylindrical hydrogen fuel tanks visible in the aft fuselage section, illustrating how liquid hydrogen storage would be integrated into the A320/A321 airframe for medium- and long-range zero-emission flight.

    Why electric airplanes are no panacea

    The (very) good news is that there is more than one zero-emission aviation technology coming. But at the risk of being Mr. Negative, at least for airport communities, electric airplanes are no panacea. And we say that not to inspire despair but to tell residents the realities, which are: Each of these alternatives comes with

Issues

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
