Crop production: how much does nitrogen fertilizer increase yields?
How much does fertilizer increase crop yields? Aggregating all of the global data, a good rule of thumb is that up to 200kg of nitrogen can be applied per acre, increasing corn crop yields from 60 bushels per acre (with no fertilizer) to 160 bushels per acre (at 200 kg/acre). But the relationship is logarithmic,…

Cryogenic air separation: costs and energy economics?
This data-file calculates the costs of cryogenic air separation units, which are important in the production of industrial gases, ammonia, metals, materials, medical applications and new energy technologies such as blue hydrogen. Good base cases are $100/ton oxygen, $20/ton nitrogen, $200/Tpa capex and 60kWh/ton of electricity (on an input air basis).

Ammonia: production costs and energy economics?
This data-file captures ammonia production costs and energy economics, starting from inputs of hydrogen and nitrogen, using the Haber process. Our base case is $450/ton NH3 and 2.4 tons/ton CO2 intensity. This matters as fertilizer production thus explains over 1% of global emissions.

Cost of capturing CO2 using membranes?
This economic model captures the costs of capturing CO2 using membranes, with a base case of $50/ton to earn 10% IRRs on early commercial deployments, and a possibility of deflating to $20/ton in next-generation membranes. This requires $50/m2 membranes, with 100-2,500 GPU permeance and 125-200x selectivity.

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…

Density of gases: by pressure and temperature?
The density of gases matters in turbines, compressors, for energy transport and energy storage. Hence this data-file models the density of gases from first principles, using the Ideal Gas Equations and the Clausius-Clapeyron Equation. High energy density is shown for methane, less so for hydrogen and ammonia. CO2, nitrogen, argon and water are also captured.

LNG liquefaction technologies: an overview?
This data-file is an overview of different LNG liquefaction technologies: APCI, APX, Optimised Cascade, Fluid Cascade, DMR, SMR, PRICO and MMLS. A typical LNG liquefaction plant has energy intensity of 280kWh/ton, consuming 5% of the input gas entering the plant, with 20kg/boe of Scope 1&2 CO2 intensity. But efficient and electric-drive compression can lower these…

Small-Scale LNG liquefaction Costs: New Opportunities?
Small-scale LNG technologies can be economic at $10/mcf, generating 15% pre-tax IRRs, off $3/mcf input gas. This data-file tabulates the line-by-line costs of typical small-scale LNG technologies (SMRs, N2 expansion). Against this baseline, we model a more cutting-edge technology, which preserves strong economics at c25x smaller scale.

Rocket fuels: an overview?
This data-file profiles five rocket fuels, based on data from 100 rockets: kerosene, hydrogen, solid fuels, nitrogen tetroxides and an exciting new-comer, LNG. Notably, SpaceX and Blue Origin are tilting away from hydrogen/kerosene and towards LNG.

Crop production: what CO2 intensity?
The CO2 intensity of producing corn averages 0.23 tons/ton, or 75kg/boe. 50% is from N2O emissions, a powerful greenhouse gas, from the breakdown of nitrogen fertilizer. Producing 1 kWh of food energy requires 9 kWh of fossil energy.
