ZeroAvia has taken delivery of a 76-seat Bombardier* Q400 airplane from Alaska Airlines.  The craft could become a test bed for ZeroAvia’s modular HyperCore motors and hydrogen fuel systems.  The Q400 will carry four times the number of passengers of the company’s current Dornier 228 twin-engine test aircraft – already having made five successful test flights. ZeroAvia proclaims, “The future of flight is renewable hydrogen,” and explains with a mission statement.  “From 20 seat regional trips to over 100 seat long-distance flights, ZeroAvia enables scalable, sustainable aviation by replacing conventional engines with hydrogen-electric powertrains.” Two Dorniers, one in the United Kingdom and one in Hollister, California, are undergoing test flights (five so far in the Cotswolds in England) or awaiting FAA approval for such flights in Hollister. Acquiring the Bombardier brought a lot of attention to the Everett, Washington area recently, where ZeroAvia has a development center.  Governor Jay Inslee came to inspect the project Q400 and prophecy about an increasingly …

We covered Washington Governor Jay Inslee’s visit to the Group 14 Technologies battery plant in Woodinville last year.  Now the Group is getting attention from Porsche, among other funders.  The startup company announced raising $400 million from investors including the Teutonic automaker. According to Reuters, part of those funds will be used to build a second battery materials plant in eastern Washington State.  The company is now valued at over $1 billion, money which will help expand battery materials production for the silicon-lithium cell market. Silicon is a desirable material in batteries, capable of storing more energy than lithium or other metals.  It has a major drawback, though.  In expanding and contracting during charge-discharge cycles, it eventually deteriorates, crumbles, and brings the battery’s usefulness to an end. Dr. Yi Cui of Stanford University has tried various methods over the years to prevent such crumbling.  His firm, Amprius, has developed a silicon nanowire anode that enables a battery with 450 Watt-hour …
