Power grids: tenet?
…as clearly as possible. The fundamentals of electrical power, including key units of measurement, are covered on pages 4-5, again introducing the key concepts from first principles. Conventional power turbines…
Neodymium market: our top ten facts?
Neodymium is a crucial Rare Earth metal, used in permanent magnets for the ramp-up of wind turbines and electric vehicles. The market is small, growing rapidly. This could create opportunities,…
Wind power: energy costs, energy payback and EROEI?
…turbines (0.3 MWH/kW) and the tail of 20-40 smaller vessels that support offshore operations (data here). The average CO2 intensity of wind turbines is suggested at 10-20g/kWh (0.01-0.02kg/kWh). This coheres…
Glass fiber: the economics?
This data-file models the economics of producing glass fiber, the key component in fiberglass, which is used in wind turbine blades and the light-weighting of transport; but also an insulation…
Energy costs of energy transition?
…However, building all of these things absorbs energy. There are energy intensive materials in a solar plant. There are energy intensive materials in a wind-turbine. And in electric vehicles. Around…
CO2-EOR in shale: the holy grail?
…to shales across the Permian, D.J. and Powder River basins” On decarbonised gas power: “What it does is, it takes natural gas combines that with oxygen and burns it together,…
Decarbonized power: how much wind and solar fit the optimal grid?
…Pages 21-23 quantify the residual reliance on natural gas. Amazingly, even our most aggressive battery scenarios only permit 10% of gas-power capacity to be shuttered. Low-utilization gas is costly. High-utilization…
Biogas: the economics?
…landfill taxes and gas prices in different countries. Biogas production in Europe currently comprises around 1-2% of the total gas grid, although some studies have estimated that total biogas production…
UK grid volatility as renewables gain share?
…up wind today, as shown in the fascinating chart below. Gas has always been a flexible supply source. And the total share of gas has remained relatively constant at about…
Gas-to-liquids: the economics?
This data-file captures the economics of gas-to-liquids, including the formation of syngas in an auto-thermal reformer, then the subsequent upgrading into liquids via the Fischer-Tropsch reaction. Our base case is…
