Can Chemical Energy Generation Compete with Nuclear Energy's Safety and Economy?

Click For Summary

Discussion Overview

The discussion explores the potential for generating energy from chemical processes and whether these methods can be more economical and safer compared to nuclear energy. It includes considerations of various chemical reactions, energy efficiency, and situational factors affecting energy generation.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Exploratory

Main Points Raised

  • Some participants inquire about the feasibility of generating energy from chemicals in a manner that is both economical and safer than nuclear energy, mentioning processes like electron removal.
  • One participant references a method involving the electrokinetic properties of water in microchannels as a potential energy generation technique.
  • Another participant discusses the combustion of hydrocarbons (CnH(2n+2) + O2) as a more economical option than nuclear energy, while noting concerns about safety.
  • There is mention of hydrogen combustion (H2 + O2 --> H2O) but with a caveat that its safety and economics are still under development.
  • Concerns are raised about the energy efficiency of electrolysis, with a participant stating that it consumes more energy than it produces through combustion or fuel cells.
  • One participant suggests that the context of energy use (location, application) significantly influences the economic viability of different energy sources, citing solar collectors as an example in remote areas.
  • Challenges related to the storage of energy generated from chemical processes are also highlighted, indicating that current methods are not yet effective.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility and safety of chemical energy generation compared to nuclear energy. There is no consensus on which method is superior, and several points remain contested, particularly regarding the efficiency of electrolysis and the practicality of hydrogen as an energy source.

Contextual Notes

Participants note limitations regarding the energy efficiency of chemical processes, the dependence on specific conditions for energy generation, and the unresolved challenges related to energy storage and safety.

Is it possible to generate energy from chemicals in a way that would be economical, and safer compared to nuclear energy, such as the removal of electrons, etc?
 
Chemistry news on Phys.org
Well there's one way I read about that uses water in some weird way
http://www.sciencedaily.com/releases/2003/10/031020054036.htm

new method of generating electric power by harnessing the natural electrokinetic properties of a liquid, such as ordinary tap water, when it is pumped through tiny microchannels

What do you mean by "removal of electrons"? Do you mean something like a plasma or do you mean ionic compounds?
 
Well, there's always:

CnH(2n+2) + O2 --> CO2 + H2O

It's more economical then nuclear energy, but arguably less safe.

There's:

H2 + O2 --> H2O

But the safety and economics of it is still in the early development stage.

That won't work. The electrolysis takes more energy than the combustion (or fuel cell) gives off.
 
The answer depends on where, when, for what, how you are using the energy. For example, a solar collector would be cheaper in a deserted place than nuclear power 1,000 km far.

That's why it's not very economical. Obviously if they tried to make it from water it wouldn't work. Most nowdays comes from oil reserves. They're working on ways to make it biologically. There's also problems with storing it. So we're aways from making it work well.
