Metal organic frameworks: challenges and opportunities?
Metal organic frameworks (MOFs) are an exciting class of materials, which could reduce the energy penalties of CO2-separation by c80%, and reduce the cost of carbon capture to $20-40. This data-file screens companies developing metal organic frameworks, where activity has been accelerating rapidly, especially for CCS applications.

Drone companies: OEMs, inspection, defense and delivery?
This data-file is a screen of 40 leading drone companies, which either manufacturing drones for consumer, commercial and defense purposes; offer drone inspection services; or offer drone delivery services. It is a vibrant landscape, with over half of the companies founded after 2010, worth c$40bn pa, and creating c$120bn pa of economic benefits.

Gas treatment: an overview?
This data-file gives an overview of gas sweetening and treatment processes. The main method is chemical absorption using amines. We estimate that a mid-size facility of 500mmcfd must levy a $0.15/mcf cost and emits 3.5kg/boe to take out c7% H2S and CO2. Other processes are compared.

Turquoise hydrogen from methane pyrolysis: economics?
Turquoise hydrogen is produced by thermal decomposition of methane at high temperatures, from 600-1,200◦C. Costs can beat green hydrogen. This data-file quantifies the economics (in $/kg), how to generate 10% IRRs, possible capex costs, and remaining challenges for commercialization.

Power plants: average capacity?
This data-file aggregates granular data into the average capacity of different types of power plants: wind, solar, nuclear, gas, hydro, coal, biomass, landfill gas and geothermal. Energy transition is going to increase the number of inter-connections to the grid by 10-100x.

Ethylene vinyl acetate: production costs?
Ethylene vinyl acetate is produced by reacting ethylene with vinyl acetate monomer. This data-file estimates production costs, with a marginal cost between $1,500-2,000/ton, and a total embedded CO2 intensity of 3.0 tons/ton. EVA comprises 5% of the mass of a solar panel and could be an important solar bottleneck.

Flue gas desulfurization: costs of SO2 scrubbers?
This data-file captures the costs of flue gas desulfurization, specifically the costs of SO2 scrubbers, used to remove SO2 from the exhaust of coal- or distillate- fueled boilers and burners. We think a typical scrubber will remove 95% of the SO2 from the flue gas, but requires a >1c/kWh surcharge on electricity sales in order…

Global electricity prices vs. CO2 intensities?
Retail electricity prices average 11c/kWh globally, of which 50-60% is wholesale power generation, 25-35% is transmission and 10-20% covers other administrative costs of utilities. The average CO2 intensity of the global average power grid is 0.45 kg/kWh. Variations are wide. And there is a -35% correlation between electricity prices vs CO2 intensities in different countries…

Newlight AirCarbon: bioplastics breakthrough?
Newlight is converting (bio-)methane and air into polyhydroxybutyrate (PHB), a type of polyhydroxyalkanoate (PHA), a biodegradable bioplastic which it markets as AirCarbon. The product is ‘carbon negative’, biodegradable, strong, ‘never soggy’, dishwasher safe. Our AirCarbon technology review found some good underlying innovations, but was unable to de-risk cost and capex aspirations.

Bloom Energy: solid oxide fuel cell technology?
This data-file reviews Bloom Energy’s solid oxide fuel cell technology. What surprised us most was a candid overview of degradation pathways of solid oxide fuel cells, a focus on improving the longevity of fuel cells, albeit this sometimes seems to be via heavy uses of Rare Earth metals, and increasing complexity. The patents do suggest…
