Ethane cracking: the economics?
…low carbon heat and power. This solution can work well, as there are minimal process emissions, other than the heat and power demands. Although passable ethylene economics should avoid inflating…
Forest fires: what climate conclusions?
…occur: heat, fuel and oxygen. There is little chance of controlling heat or oxygen in the environment. Hence the only practical option to prevent wildfires is to remove fuel. Note…
Switching gears: the most potent GHG in the world?
…It has 3.7x higher specific heat than air, absorbing excess heat without transmitting it onwards. It is non-toxic. It is non-flammable. Hence it has become a dominant solution to ‘fill’…
Helion: linear fusion breakthrough?
…plasma to expand. Energy is then captured from the expanding plasma. It is like fuel in a diesel engine. (3) Direct electricity generation. Most power generators work by producing heat….
How does CO2 increase global temperature?
…any heat itself. It is simply re-radiating and re-scattering heat that would otherwise be travelling in a more direct path back into space. This effect of CO2, and other greenhouse…
Building automation: energy savings, KNX case studies and companies?
…average energy saving is 40%. Typical functionality is similar to heating described above. In addition, the KNX system might close blinds during the day to prevent heat gain in a…
Gas turbines: operating parameters?
A typical simple-cycle gas turbine is sized at 200MW, and achieves 38% efficiency, as super-heated gases at 1,250ºC temperature and 100-bar pressure expand to drive a turbine. The exhaust gas…
Naphtha cracking: costs of ethylene, propylene and aromatics?
…are associated with heat, electricity and CO2 prices, which can also be varied in the data-file. Energy costs are quantified from technical papers, across electricity use and heat use, both…
Thermodynamics of prime movers: energy from first principles?
…flat on 1960, with around 60 million horses in the world today, showing how hard it is to disrupt established technologies. https://thundersaidenergy.com/downloads/the-2050-energy-mix-a-simple-model/ Heat engines changed the world, starting with coal-fired…
Compressed air energy storage: costs and economics?
…gases cooling during storage (see below). When gases are compressed they tend to heat up. For example, in an isentropic process — where heat is not exchanged with the external…
