"Never Stop Your Learning"
Prem Murjani : No words for this level of explanation
Pranoti P : Short, simple and satisfactory. Keep up the good work guys!
Guilherme Teixeira : Which type of material is the fuel cell made of?
Salif Yoda : Could this application be used in order to generate electricity in coastal regions as well as the developers working on floating cities.

The only thing missing are water fuel center stations ⛽
Mark Indiongco : If eGallon is the cost of fueling a vehicle with ELECTRICITY compared to a similar vehicle that runs on gasoline, what do you call the cost of fueling a vehicle with HYDROGEN compared to a similar vehicle that runs on gasoline?

How Fuel Cells Work

An overview on how our fuel cell plants produce megawatts of power - cleanly and efficiently.
MrLaftis : Is there a way to scale down a carbon capture unit to be use on a semi-trailer truck and other vehicle mufflers to reduce carbon dioxide?
Rey Police : @ fuel cell energy.

Thank you for your video describing your technology.

Some questions need to be answered please.

1. For giving amount of BTUs natural gas what is the given amount of output BTUs in electrical DC for your unit?

What is the actual efficiency?

2. To convert DC to AC to power the grid there is a 30% loss of DC power to AC in transforming from DC to AC.

3. After it is stepped up to AC for high voltage transmission there is a 40% loss in AC transmission lines to end user.

4. Since your system produces some CO2 and possibly other gases what capture system do you have that captures the CO2, as your unit is quite large it's producing quite a lot of co2.

A) what amount of CO2 / nitrous oxide, and other gases is your unit producing, per kilowatt or per a megawatt?

B) what scrubber systems do you have in place that will handle the capture of the CO2 and other toxic gases produced by your unit.

5. Your system still slaves people to natural gas, or biogas. Can you please build a system that works off of hydrogen. Hydrogen is much cleaner and easier to produce than natural gas or biofuels from tires.

In closing:

What is the smallest unit you produce for home installation? Do you have a 2 KWe to 5 KWe for home installation or greater for factory installation.

As I already have access to natural gas and or biofuel, and have a way to do carbon and other toxic gas scrubbing.

Please respond thank you.
Zane Farmer : this is the best “how it works” video i’ve ever seen
Lem Bajarias : wow...
xTheKingsGuard : Is this technology going to start getting more popular now that the world seems to be switching to clean energy ?

Hydrogen \u0026 Fuel Cells | Reactions | Chemistry | FuseSchool

In this video, you will learn about how we are trying to design a way to power vehicles of the future on hydrogen, oxygen and sunlight.

In order to obtain energy for the vehicle from hydrogen (that is stored as a fuel cell for motor vehicles), we need to rejoin the hydrogen with oxygen. This is done most efficiently in what is called a fuel cell.

In an ordinary electric cell, a metal, say zinc, ionizes at one electrode, the anode, giving off two electrons. The electrons are pushed around the circuit carrying energy, to, for example, a motor and absorbed by metal ions of a less reactive metal, say copper. The circuit is completed by the movement of metal ions through the solution.

In a fuel cell, the reactants are gases instead of metals. Hydrogen gives its electrons. The electrons flow round, driving the motor, and arrive at the cathode where they are recombined with hydrogen in the presence of the reactive gas oxygen, which provides the driving energy to form water again. The electrodes can be made of porous carbon coated with a catalyst, such as platinum or nickel.

The advantage of combining a fuel and oxygen in a cell is that you can in theory convert most of the chemical energy to electricity whereas burning them, as happens in the internal combustion engine of a car, has a maximum efficiency of about 50% and in practice only about 25% of the chemical energy does useful work in driving the engine - the rest comes out as waste heat.

There are two major problems to using hydrogen fuel cells in vehicles.

Firstly, where do you get the hydrogen? Currently most industrial hydrogen is derived from methane and the carbon is rejected as carbon dioxide, thus adding to the greenhouse effect. The hope is that we can learn to mimic photosynthesis by using sunlight to split water molecules apart, giving us a clean and simple source of hydrogen. Currently this is achieved by using photovoltaic cells to generate electricity, which then electrolyses water, forming hydrogen and oxygen. To take the analogy further, the hydrogen is transported to the fuel cell, like biomass passing along a food chain, and the oxygen, which we tend to take for granted, is vented to the atmosphere. The fuel cell then gets its oxygen from the atmosphere, just like in respiration. The energy is stored whilst the hydrogen and oxygen are kept apart.

The other problem is how to store and transport the hydrogen gas once you've got it. It's extremely difficult to liquefy and rather dangerous if kept as a gas under pressure, particularly if the vehicle crashes. Research is therefore focusing on hydrides, compounds of elements with hydrogen, which are solid or liquid at room temperature and which give out their hydrogen reversibly and without too much energy input. This allows hydrogen to be pumped in, reacting to form the hydride and, then, on the journey, the hydrogen is given off to be used in the fuel cell to drive the vehicle. For example, ammonia borane, a solid at room temperature with the same structure of ethane, gives up its hydrogen on heating.

However, it will probably be more energy efficient to run the cars on batteries which are charged from green electricity.

Fuel cells generate electricity from the reaction between a fuel and oxygen. Using them on vehicles means that we need to develop a way of storing hydrogen, which is difficult. It is more likely that vehicles of the future will be powered by batteries.

Angus Chandler : The one big advantage of using hydrogen fuel cells over current electric cars (no pun intended) is lithium ions only have an energy density of 250wh/kg, whereas hydrogen has roughly over 39,000wh/kg
Jeff Tormey : It’s crazy how he casually writes off the ability to store hydrogen safely.
Coolnessmortez Channel : Lots of processing goes into hydrogen about the only thing I didn’t like about hydrogen was the explosive effects and batteries are near solid state level with out blowing up / you can use algae to produce hydrogen and make more efficient hydrogen stations/ with discharge water disposal and electrolysis in case you need more hydrogen or algae hydrogen overflow and balance it out with ultra capacitors
G. Dave3 : Hydrogen can be compressed like any other gas, and can be made in situ at fuel stations and even houses. If a Wind or Water turbine( perhaps a micro hydro turbine powered by water mains pipes, which are already being installed in a few places). Combined with some Solar for back up. It would be very easy to make and compress Hydrogen at fuel stations. The Orkney Islands are using their excess Wind energy to split water to make Hydrogen, which they use in a Fuel Cell at the ferry port to power the Port and associated buildings etc, they also use the heat generated to heat the Port buildings. The excess Hydrogen is sold to the mainland and brings an income to the Island. They plan on using their Hydrogen in Fuel Cells to power the Ferries to the mainland when the current Ferries come to the end of their service life. Here’s a link from one of the Islanders who explains how it works.
Vishank : This is beautiful on multiple levels! Really appreciate your work sir.
