“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.

Ultracapacitors for EVs

“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.

“How can we produce Hydrogen Gas using Ethanol?”

 

Natural Gas Reformation is currently the most popular way to produce hydrogen gas. However, a large amount of greenhouse gases are released in the process, contributing to climate change. So is there a more sustainable way to produce hydrogen gas? Well, it turns out that Ethanol is an amazing substitute for natural gas! Therefore, we can Produce Hydrogen Gas using Ethanol.

“How can we produce hydrogen using electricity?”

 

Hydrogen is an amazing material. However, extracting it can be quite difficult. One way to do it is to take an anode and a cathode separated by an electrolyte and a membrane. The water will react at the anode to produce oxygen and positively charged hydrogen ions. The electrons will flow through the circuit and the hydrogen ions will move across the membrane to the cathode side. They will then meet and recombine to form hydrogen molecules. This way, we can Produce Hydrogen using Electrolysis. Since the only thing that needs to be added to the system is electricity, if our grid is powered by renewables then we can have a carbon neutral method of hydrogen production!

“How can we obtain Hydrogen from Natural Gas?”

 

Hydrogen is just as difficult to extract as it is useful. But luckily, there is one method which is able to produce it in a cost effective manner. Most of this is done in a process where high-temperature steam (700°C–1,000°C) is combined with a methane source such as Natural Gas under high pressures (around 2-35 bar) to produce hydrogen, carbon monoxide, and a relatively small amount of carbon dioxide. This process is known as Natural Gas Reforming and is used to create 95% of the natural gas supplies in the U.S.
