The high costs of hydrogen vehicles and hydrogen fuels also represent obstacles to wider adoption. For example, in China – the world’s largest hydrogen developer and the biggest FCEV market – current hydrogen-powered heavy-duty trucks can cost around 1 million yuan (US$138,400), almost trip...
Deuterium is madeby separating naturally-occurring heavy water from a large volume of natural water. Deuterium could be produced in a nuclear reactor, but the method is not cost-effective. How does hydrogen become deuterium? Hydrogen has no neutron, deuterium has one, and tritium has two neutron...
Volumetric energy density, other wise known as energy-to-size ratio, is how much energy can be stored in an energy storage medium per litre of that medium. It is measured in Wh/Litre or Wh/L, because the litre is a measure of volume. It is not to be confused with weight or mass ...
I decided to just go with it and use the last one I had in my hand…other than the bad staining, it was clean. I did not want to attract any attention by flipping through all the mugs on my first day at the job, oh boy! I bided my time but within a month all the teacups &...
There were many priorities in the discussion, for topics related to customs and trade, there were discussions on trade and investment; the mining industry and critical minerals and sustainable and renewable energy including green hydrogen and energy efficiency. Our take: It is worth noting that ...
How much does 1 kg of plutonium cost? Since the energy per fission from plutonium-239 and uranium-235 is about the same, the theoretical fuel value of fissile plutonium can be put at $5,600 per kilogram. Reactor-grade plutonium also contains non-fissile isotopes, reducing its value to abou...
Beware of over priming your beer. If you add too much sugar, too much CO2 will be produced by the yeast and it will have nowhere to escape. It will escape in the form of a'gusher' when you open your beerand it will gush out the next of the bottle like a geyser and go bloody ...
So what does this mean for you? How much vitamin C and sugar you have to mix into your cup of tea? The report didn’t mention this, but we can estimate from the ratio of EGCG to vitamin C and sugar. The drink contained 30mg of EGCG, 10mg of vitamin C and 1.2g of sugar. Your...
Even at home gas prices you could refuel at an equivalent of $0.70 per litre. Conversion of vehicles costs around $4000, but I am sure that this would be much lower if it was factory fitted. CNG should be equally attractive for industrial equipment. I am currently engaged in convincing a...
Fill your fermenter to 6 gallons of water or to the 23 litre mark. Stick with that, your malt kit recipe has been designed with exactly this amount of water in mind. If you add too much water, you will dilute your beer. Adding less water may result in a stronger beer but at the ...
