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…
Semiconductors: outlook in energy transition?
…will underpin 1,000 TWH of internet energy consumption, in turn boosting demand for gas, gas pipelines, gas turbines, uranium, industrial cooling equipment, fiber optics, and unlocking transformative new technologies including…
Post-combustion CCS: what energy penalties?
…a coal plant can meet all of its amine reboiler duty using waste heat, which would otherwise simply have condensed in a cooling tower, then its CCS energy penalties are…
Gas fractionation: NGL economics?
…butane, C5s and C6+ fractions, which are entrained in the gas. These condensates or natural gas liquids (NGLs) can be removed by first dehydrating the gas, then, cryogenically cooling it,…
Energy needed to produce steam: enthalpy and entropy data?
…the water phase. And less energy must be re-added to compensate for the cooling effects of gas expansion. Critical point of steam illustrated via the enthalpy of saturation steam versus…
NEL: green hydrogen technology review?
…our usual framework. A large majority of NEL’s recent patents are focused on hydrogen fuelling stations, including compression, storage tanks, safety features, cooling the hydrogen stream, testing the fuelling stations…
Albedo of different landscapes: a challenge for reforestation?
…8%). However, overall, a 7pp heat absorption delta on 2.4% of the world’s land is a rounding error. And it may itself be counteracted… (3) Clouds and the cooling impacts…
How does methane increase global temperature?
…numbers. Aerosol interactions. Recent research has also alleged that methane lowers the prevalence of climate-cooling aerosols in the atmosphere, and this may increase the warming impacts of CH4 by as…
Prysmian: power cable technology breakthroughs?
…around its optical and power cabling solutions: from real-simplified testing while installing ultra-deepwater HVDCs to cooling EV fast-charging cables. Full details on Prysmian power cable technology are in the data-file….
Energy security: volcanos versus solar panels?
…upper atmosphere, dimming the sun, and thus cooling the climate by 0.5-1.2 C for 1-3 years. Solar energy implications? So what happens as we build out solar generation in our…
