Heart Aerospace, on the airport at Gothenburg Airport in southern Sweden, wants to bring inexpensive, four-motor electric flight to the masses.  With $35 million (29.4 million euros) in recently acquired backing, the small team at Heart is working toward making a 19-passenger, four-motor airliner a reality.  Their ES-19 is a single-aisle design with eight-rows of single seats and three-seat row at the cabin’s rear. Those 19 seats are a selling point, with United Airlines signing purchase contracts for 100 of the $ 9 million machines.  Mesa Airlines follows suit for another 100 and Finnair, Finland’s national airline, has expressed interest in another 20.  Funding from Bill Gates’ Breakthrough Energy Ventures and other investors totals over $35 million.  For a niche …

“Cannot be more proud and humbled to be a part of this stellar team!”  That’s power system developer Gabriel DeVault’s response to ZeroAvia’s Chief Financial Officer Katya Akulinicheva’s enthusiastic endorsement of Bloomberg LP’s news.  She listed the investors taking an active interest in ZeroAvia, including Ecosystem Integrity Fund, Breakthrough Energy Ventures, the Amazon Climate Pledge Fund, Horizons Ventures, Shell Ventures and Summa Equity. Already benefiting from a $16.3 million grant from Innovate UK, Aerospace Technology Institute and Department for Business, Energy and Industrial Strategy (BEIS), ZeroAvia will be able to push forward on plans to create a 19-seat hydrogen-powered commuter liner. According to Bloomberg, “ZeroAvia aims to demonstrate that it can fly a plane 500 miles (804 kilometers) with as …

Quantumscape Batteries – an Emerging Answer

Dean Sigler Batteries, Sustainable Aviation Leave a Comment

Hiding in plain site next to the San Jose, California International Airport, Quantumscape has been quietly developing a solid-state battery now emerging and trending toward mass production.  With backing from Volkswagen, Bill Gates and a founding member of Tesla, the battery company would make big splash if it used a liquid electrolyte.  It doesn’t.  Wired goes a bit dramatic in describing the faults of batteries with liquid electrolytes.  “IF ELECTRIC VEHICLES are ever going to fully supplant gas guzzlers on the world’s roads, they’re going to need an entirely new type of battery. Despite steady improvements over the past decade in the energy density and lifetimes of lithium-ion batteries, the cells in new EVs still lag behind internal combustion engines …

Making Greener-Than-Green Hydrogen

Dean Sigler Biofuels, Fuel Cells, Hydrogen Fuel, Sustainable Aviation Leave a Comment

What if we could make “clean” hydrogen from plain water, with none of the problems associated with coal, oil or gas extraction and the waste byproducts produced in extracting brown or blue H2?  Several approaches such as artificial leaves have been developed, but a totally different new approach seems incredibly promising.  A promising approach may lead to greener-than-green hydrogen. The Race to Invent the Artificial Leaf Varun Sivaram, in his book Taming the Sun discusses how Nate Lewis at Caltech and Daniel Nocera at Harvard “determined to find a way to wring fuel out of thin air.”  Each has created an “artificial leaf” that emulates the photosynthesis performed naturally by real leaves. A real leaf is far more complex than …
