New energies: filter feeder?

Harmonic distortions have several detrimental effects on electrical systems. Harmonic filters reduce the amount of total distortions in a system, providing power savings and reducing equipment degradation.

…otherwise jagged, causing resistive losses, excess heat generation and equipment degradation. These issues are explained on pages 2-4. Case studies of harmonic distortion, and their negative consequences, are described on…

CCS: what CO2 purity for transport and disposal?

CO2 purity required for various purposes. The highest purities are required by food, beverage, and medical purposes, as well as shipping and liquefaction. CO2 disposal has the highest variability. For any purpose the purity must still be at least 90%.

…less than 100% CO2, then by definition, it must contain something else. Clearly, issues will arise is the ‘what else’ is toxic or hazardous (e.g., H2S, amine degradation products such…
