Cable installation vessels: costs and operating parameters?
This is a database of cable installation vessels for offshore wind and power transmission; tabulating costs (in $M), contract awards (in $/km), capacity (in tons), installation speeds (in meters per hour), power ratings (in MW), crew sizes and positioning systems. There is a paradox over costs.

Offshore wind: installation costs by vessel?
An offshore wind project is likely to cost $2,500/kW, of which c$1,500/kW is turbines and $1,000/kW is offshore installation costs. This data-file aims to estimate the breakdown by vessel type, day-rates and costs per turbine.

Gas turbines: operating parameters?
A typical simple-cycle gas turbine is sized at 200MW, and achieves 38% efficiency, as super-heated gases at 1,250ºC temperature and 100-bar pressure expand to drive a turbine. The exhaust gas is still at about 600ºC. In a combined cycle gas plant, this heat can be used to produce steam that drives an additional turbine, adding…

Prime movers: efficiency of power generation over time?
How has the efficiency of prime movers increased across industrial history? This data-file profiles the continued progress in the efficiency of power generation over time, from 1650 to 2050e. As a rule of thumb, the energy system has shifted to become ever more efficient over the past 400-years.

US electric utilities: leading companies in transmission and distribution?
The average US electric utility has 25 GW of generation, 15,000-miles of power transmission, 100,000 miles of distribution, 8M customers, 3.5% dividend yields and 6.5% long-term target growth. We wonder if there is upside on expanding power grids? A dozen companies are in our screen.

Direct reduced iron: costs and projects?
Direct reduced iron (DRI) is produced by reacting iron ore with H2-CO syngas, fueled by natural gas, in over 150 facilities worldwide. Direct reduction iron costs $300/ton, consuming 3,000kWh/ton of energy and CO2 intensity of 0.6 tons/ton. The process can be decarbonized via low-carbon hydrogen in the syngas, as the world strives towards decarbonized steel.

Cement costs and energy economics?
This data-file captures cement costs, based on inputs, capex and energy economics. A typical cement plant requires a cement price of $130/ton for a 10% IRR, on capex costs of $200/Tpa, energy intensity of 1,000 kWh/ton and CO2 intensity of 0.9 tons/ton. Cement costs can be stress tested in the data-file.

Residential energy consumption over time?
Global residential energy demand runs at 2.5 MWH pp pa, of which c40% is from electricity, 40% is gas, c13% is biomass and c7% is oil. In our gas and power models, electrification rises to 65% by 2050, to help renewables reach 50% of global electricity. Heat pumps improve efficiency and lower primary demand in the developed world.

Origen Carbon: DAC breakthrough?
Origen Carbon Solutions is developing a novel DAC technology, producing CaO sorbent via the oxy-fuelled calcining of limestone with no net CO2 emissions. It is similar to the NET Power cycle, but adapted for a limestone kiln. The concept is very interesting. Our base case costs are $200-300/ton of CO2. This data-file contains our Origen…
