…marketed as AirCarbon. The product is said to be carbon negative, biodegradable, strong, “never soggy”, dishwasher safe. Our AirCarbon technology review found some good underlying innovations, but was unable to…
…need for clean, small-scale generation in the energy transition (note here). How does a solid oxide fuel cell work? A solid oxide fuel cell draws in air at the cathode,…
…reduces anthraquinone. The reduced anthraquinone can later be oxidized, in the presence of air, forming both H2O2 and H2O, and regenerating the anthraquinone. The process uses a palladium catalyst. It…
…other hand, new categories of demand, such as air conditioning and other appliances, have more than offset the efficiency improvements in individual devices such as refrigerators. Heating demand for houses…
…world aviation (page 12), US air conditioning (page 13-14) and US residential electricity use (page 15). Our conclusions from the analysis suggest it will be harder to use energy efficiency…
…the demand is highly variable, troughing at 15GW in April-2022 and peaking at over 61GW in July-2021. Summer demand is almost 50% higher than winter demand due to air conditioning….
…Cost of medium duration energy storage solutions from lithium batteries to thermal pumped hydro and compressed air Energy storage and power ratings can be flexed somewhat independently. You could easily…
…But anions and gases are impeded. This is even the reason that the SpaceX’s Dragon space probe used Nafion membrane to dehumidify air against a vacuum. Costs of Nafion membranes…
