“How can aircraft be powered by hydrogen?”

The worst problems with aircraft and sustainability is the fact that they are powered by GHG-ridden fuels. This can be offset by creating aircraft powered by electrolysis-based hydrogen. This results in Hydrogen-Powered Aircraft.

“What are the dangers of liquid hydrogen fuel in vehicles?”

Hydrogen fuel cell vehicles are a very hot research topic. However, liquid hydrogen vehicles present some strong dangers. Although sealed hydrogen is relatively safe, exposed hydrogen has some factors which can make it less so. First of all, hydrogen can catch fire really easily as it only requires 1/10th of the energy to combust compared to gas. Hydrogen flames are also nearly invisible and can displace oxygen in human lungs, making it a very silent killer. This is Why Liquid Hydrogen in Vehicles Can Be Very Dangerous.

“What is a more optimal fuel than gasoline?”

 

While gasoline is the most widespread vehicle fuel in the world, recent advances in science and technology have created competitors. One in particular comes in the form of Methanol Fuel. Methanol fuel is synthesized from carbon dioxide and hydrogen burns cleaner and is cheaper to produce sustainably than ethanol. Since it does not produce a thick cloud of smoke upon use, it is often used in racing applications. Although methanol is less toxic than petroleum, there exist very few methanol refueling stations, it is commonly found in a mixture with other fuels.

“What is one possible way to speed up EV recharge times?”

 

In order to achieve deep-decarbonization of transportation, the global vehicle fleet needs to become much more electrified. However, the long recharge times associated with electric vehicles are a roadblock for this to happen. One way to solve this would be to implement Ultracapacitors for EVs. Ultracapacitors have quick recharge times, low weight, and low degradation, making them a formidable option. The downside is that manny ultracapacitors lack the storage capacity found in traditional solid-state batteries. But if this problem gets solved, then expect a paradigm shift in the EV industry!

“Why might hydrogen fuels cells be the future of heavy trucking?”

 

In order to decarbonize heavy trucking freight transport, the replacement system needs to have high energy density and low weight so it doesn’t bog down the cars on their long rides. This way Hydrogen Fuel Cells would be perfect due to satisfying both of these. This is Why Hydrogen Fuel Cells Work for Heavy Trucking.

“What will be one of the biggest drivers of energy sustainability with batteries?”

 

Battery supplies are increasing at an exponential rate. But one of their greatest applications will be in night-time energy storage. By being able to integrate with solar and wind, people will be able to reduce their reliance on pollutive peaker plants for energy generation during night time. This is Why Increasing Battery Supply for Night Time Energy Supply Can Result in Massive Decarbonization.
