Monday April 9th… Dear Diary. The main purpose of this ongoing post will be to track United States extreme or record temperatures related to climate change. Any reports I see of ETs will be listed below the main topic of the day. I’ll refer to extreme or record temperatures as ETs (not extraterrestrials)😊. Here is today’s main climate change related topic:
Hydrogen as a Fuel?
Around the dawn of the 21st century I heard a lot about hydrogen being a good alternative for fossil fuels in cars. Gradually electrics filled that void, so I saw less news about automobile companies coming up with new vehicle designs to employ the hydrogen fuel cell. Last week I did see one more though:
The article that I’ve referred to doesn’t mention climate change, just the fact that fossil fuels are a finite source of energy. They do bring up a good point which I will quote: If you eliminate infrastructure issues from consideration for a moment, utilizing the most abundant element in the universe, hydrogen, as an energy source makes a lot of sense. Hydrogen as a vehicular fuel, according to Hyundai, is also a question of when. Unlike energy-storage devices such as batteries or capacitors, once H2 is captured and pressurized, the losses are minimal. Storing 100 kilowatt-hours in a battery for a year is impossible because the state of charge drops over time. Fuel cells do lose some efficiency in cold climates, but not nearly as dramatically as one will encounter with batteries. Yes, pressurized hydrogen can be dangerous. However, there are other ways to store hydrogen for long durations—in ammonia, for example—that involve less risk.
At $55,000 the 2019 Hyundai Nexo is pretty pricey, so for the next several years even the all electric but cheaper Tesla models will probably be more popular with the public. Being someone who thinks that some capitalism should get us out of climate change mess I welcome competition to bring cost of alternative solutions down. P.S. Elon Musk, the CEO of Tesla really frowns on hydrogen fuel cells. Yet, the hydrogen fuel cell might be another tool in the toolkit to help solve the climate crisis. Here is more science behind the fuel cell stack:
Hydrogen might also be an alternative to generate power plant electricity:
The above linked U-Tube video shows the largest hydrogen electric generating plant in the world in South Korea. I would invite all to look at other videos from the same link to see the pros and cons of hydrogen. My biggest problem with hydrogen is its volatility. Remember the Hindenburg from 1937? Well, you get the picture. Others see economic problems for hydrogen:
The more I look at the current cold wave hitting much of the U.S. the more I am impressed. This cold is going to put a real dent in those warm record stats not ending anytime soon:
This is still in track. It’s extremely hard to link a blizzard to global warming, but as noted a few days ago Arctic warmth and the breakdown of the polar vortex are interacting with storm systems:
