Is hydrogen the answer for jet fuel?

Something has happened in China — leading the USA in research for the past three years — with electrolyzer design and efficiency. What’s an electrolyzer? It’s the machine that splits water into oxygen and hydrogen and, in China, they have produced a commercial electrolyzer — already on sale — that is 80% more efficient than the models that we make and sell in the USA. Oh, and theirs are now being exported throughout the world.

Why? Because, pound for pound, hydrogen is 3.3 times more powerful — produces more kWh/kg — than jet fuel. And jet fuel is 1.5 times for powerful than the gasoline you pump into your car. That means if your car was using hydrogen — yes, in the same engine you already have (albeit with a different carburetor and computer control) — you would get a fuel efficiency almost five times as great. You get 20 mpg now? You would get almost 100 mpg. But hydrogen is currently really expensive… well, not anymore. With the electrolyzers from China, the cost per gallon (remember that’s five times the energy) is about three times the cost of premium gas — you make a saving either way.

Oh, and when you burn hydrogen there is no tailpipe, just a drain dropping clean distilled water on the road. In arid areas, you can collect it and water your plants.

Now, in cars, that install and use is easily possible and, in fact, Honda and Toyota already have sold vehicles in California and Washington, D.C., in tests much like they did for the Prius in 1995. But the real secret here is air travel. Hydrogen works perfectly with existing jet engines.

The electrolyzer uses a lot of electricity to break apart the water into oxygen (pumped into the air) and then to collect hydrogen under pressure. The larger the plant, the more juice it needs yet bigger the efficiency. Putting commercial electrolyzers next to nuclear power plants that waste unwanted electricity at night makes sense for everyone — especially the environment.

Yes, liquefaction problems exist. Safety concerns exist. Weight of tanks to safely hold the hydrogen in airplanes exist. But these are technical and engineering issues we can solve. Imagine taking off from New York, flying to Hawaii, using a fifth of the fuel and making a clean water contrail along the way. Cheaper, cleaner, environmentally friendly.

OK, there is an issue, which China is advancing ahead of every other nation: Electrolyzers depend on rare earth metals, especially platinum and iridium. The world-wide search is on, with China cornering the market (no surprise since we gave up on joint world trade for four years). One last tidbit though… Japan recently returned soil samples from an asteroid to earth. Guess what elements seemed plentiful in their sampling? The space race is about the get really interesting.

Farewell to a visionary leader: Amy Wynn departs AMP after seven years

When longtime arts administrator Amy Wynn became the first executive director of the American Mural Project (AMP) in 2018, the nonprofit was part visionary art endeavor, part construction site and part experiment in collaboration.

Today, AMP stands as a fully realized arts destination, home to the world’s largest indoor collaborative artwork and a thriving hub for community engagement. Wynn’s departure, marked by her final day Oct. 31, closes a significant chapter in the organization’s evolution. Staff and supporters gathered the afternoon before to celebrate her tenure with stories, laughter and warm tributes.

The Norfolk Library will screen the acclaimed documentary “Kings of Pastry” on Friday, Nov. 14, at 7 p.m. The film will be introduced by its producer, Salisbury resident Flora Lazar, who will also take part in a Q&A following the screening.

Directed by legendary documentarians D.A. Pennebaker (“Don’t Look Back,” “Monterey Pop”) and Chris Hegedus (“The War Room”), “Kings of Pastry” offers a rare, behind-the-scenes look at the prestigious Meilleurs Ouvriers de France (Best Craftsmen of France) competition, a prestigious national award recognizing mastery across dozens of trades, from pastry to high technology. Pennebaker, who attended The Salisbury School, was a pioneer of cinéma vérité and received an honorary Academy Award for lifetime achievement.

On Saturday, Nov. 15, the Stissing Center in Pine Plains will be host to the Hudson Valley premiere of the award-winning music documentary “Coming Home: The Guggenheim Grotto Back in Ireland.” The screening will be followed by an intimate acoustic set from Mick Lynch, one half of the beloved Irish folk duo The Guggenheim Grotto.

The film’s director, Will Chase, is an accomplished and recognizable actor with leading and supporting roles in “Law & Order,” “The Good Wife,” “Rescue Me,” “Nashville,” “The Deuce,” “Stranger Things” and “Dopesick.” After decades of acting on television and on Broadway, Chase decided to take the plunge into directing his own short films and documentaries.
