Albedo of different landscapes: a challenge for reforestation?
…true that land uses with a lower albedo will absorb more heat. But how much more heat? (2) Albedo impacts are a rounding error? Overall, our roadmap to net zero…
Prysmian E3X: reconductoring technology?
…sag causing electrical hazards. For comparison, note that bare aluminium cables have a notoriously poor heat emissivity factor, around 0.16x, which is one of the key reasons they heat up…
The green hydrogen economy: a summary?
…in the energy transition. For example, we estimate that using blue hydrogen to decarbonize heat would raise an average household’s heating bill by c$670 per year, while green hydrogen would…
Energy Recovery Inc: pressure exchanger technology?
…of pressure exchangers, especially for the desalination industry, and increasingly for refrigeration, air conditioners, heat pump and industrial applications. Our technology review finds a strong patent library and moat around…
Thermodynamics of prime movers: energy from first principles?
…high-grade gas turbines. Muscle power was the original prime mover in the pre-industrial energy system (chart below). But a typical horse outputs 0.75 kW of power, converts only c10-30% of…
European gas and power model: natural gas supply-demand?
…residential heating, c10% in commercial heating, c25% in electricity generation, and smaller quantities in T&D and transportation (chart below). Gas demand is disaggregated across a dozen different industries in the…
Efficient frontiers: improvements from a CO2 price within oil and gas?
Efficiencies from an imposed CO2 price of $40-80/ton could double the pace of industrial gains in the oil and gas sector, eliminating 15-20% of its CO2 emissions, as outlined in…
Energy Technologies and Energy Transition
…energy mix, treble demand for natural gas, pursue industrial efficiency gains, make fossil fuels the most efficient and lowest carbon possible, and then capture or offset the remaining CO2. Total…
Heliogen: concentrated solar breakthrough?
…heliostats to be down-sized, conferring material cost-savings. This data-file summarizes the technology, the patents, the costs (in c/kWh and $/mcfe) and the opportunity to decarbonise industrial heat and power generation….
Methane leaks: by gas source and use
…consumers such as power plants, LNG plants, ammonia plants, hydrogen reformers, industrial heating and households. Hence in the title chart above, we have attempted to build up the methane intensity…
