Offshore wind: levelized costs?

levelized cost of offshore wind

…Chrysler building. Base case IRRs would be in single digits. The model explores how hypothetical initiatives might uplift the returns, including power marketing, continued cost-deflation, leverage, carbon prices and feed-in…

Gas fractionation: NGL economics?

Gas fractionation

…important to provide feedstocks for advanced polymers used in new energies and energy efficiency technologies. But we also see a growing role for low-carbon natural gas in the energy transition….

Boltzmann energy overview?

Cathode active materials

…to occur in hotter thermodynamic systems. Arrhenius equation relating reaction rate coefficient to temperature and determining activation energy Carbon removal applications? Nature based solutions are low-cost and help nature, but…

DAC to the future?

Direct air capture

…costs and 500kWh/ton energy use (page 5). Liquid DAC (L-DAC) uses alkali solvents to react with ambient CO2, and has gained prominence through Carbon Engineering and Occidental. Advantages and challenges…

MOSFETs: energy use and power loss calculator?

MOSFETs are fast-acting digital switches, used to transform electricity, across new energies and digital devices. MOSFET power losses are built up from first principles in this data-file, averaging 2% per…

Pump costs: energy economics of electric pumps?

As pump power increases, pump costs per kWh decrease. The most significant reduction is in pump maintenance costs, while the total cost of electricity remains constant.

…industry are also modelled in two further back-up tabs. A typical Electric Submersible Pump (ESP) will contribute $0.3/boe of cost and 5kg/boe of carbon, if powered by diesel, at a…

Enhanced geothermal: digging deeper?

Initial costs of enhanced geothermal projects are likely 10-15 c/kWh-th, equivalent to $40/mcfe, but capex deflation can reduce costs by at least 30-50%, possibly more...

…and as pilot projects have de-risked novel well designs. This 18-page report re-evaluates the energy economics of geothermal from first principles. Is there a path to cost-competitive, zero-carbon baseload heat?…

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%.

…of CO2 disposal, across various technologies, from straight-run amine CCS, to DAC, CO2-EOR, blue hydrogen SMRs and ATRs, oxy-combustion, potassium carbonate, other sorbents, next-gen membranes. But what CO2 purity levels…

Bright green hydrogen from biomass gasification?

…sequesters the carbon in biomass, addressing challenges over the permanence of some nature-based CO2 removals. The economics of biomass gasification are modelled in this data-file, albeit screening as somewhat expensive,…
