Why Increasing Battery Supply for Night Time Energy Supply Can Result in Massive Decarbonization
“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 to Produce Hydrogen Gas using Ethanol
“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.
Hydrogen Production through Electrolysis
“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!

Natural Gas Reforming
“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.

How can we obtain Hydrogen Fuel?
“How can we obtain Hydrogen Fuel?”
Hydrogen Fuel (H2) is an invaluable resource. Whether it be for powering hydrogen fuel cell batteries or making agricultural fertilizer. However, because of its special bonding properties, pure hydrogen is incredibly difficult to extract. So how can we use our engineering mindset to solve this problem? Well, there are a number of different ways. Natural gas can be reacted with high-temperature steam to for water to create H2 and Co, a very high power electric current can split water into dihydrogen and oxygen, Renewable liquid fuels, such as ethanol, can be reacted with high-temperature steam to obtain H2, and biological fermentation can occur. In the end there are many ways to make our desired fuel in a safe and economical manner.
The Physics of a Fireworks Explosion
“What causes fireworks to explode?”
On 4th of July, Americans are used to seeing fireworks light up the night sky. However, have you ever wondered how exactly do they work? Well, let us use our scientific mindsets to find out. If we investigate, then we will find out that fireworks contain gunpowder in a container surrounded by a Launch Container. When a Lift Charge ignites and propels the container into the sky, there will be a time delay until it reaches its apex, at which it will explode and release a myriad of different colors!
Have a great 4th of July everyone with lots of V/I to the current regime!
“How can we improve on a process based on feedback?”
Processes are vital to modern engineering practice, whether it be in producing energy from municipal waste or in managing an industrial facility. However, sometimes we might encounter that there are some unaccounted inefficiencies within runtime. So how can we use our engineering mindset to solve this problem? Well, what if we were to simply include sensors to analyze these discrepancies, and then use feedback to modify our process until it runs completely smoothly? Well, this is the idea behind process control and is a must-have for modern-day industrial systems.
