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…

Hot potassium carbonate CCS: energy economics?
Hot potassium carbonate is a post-combustion CCS technology that bypasses the degradation issues of amines, and can help to decarbonize power, BECCS and cement plants. We think costs are around $100/ton and energy penalties are 30-50%. Potassium carbonate CCS can be stress-tested in this data-file, across 50 inputs.

Thermoelectrics: leading companies and products?
Thermoelectric devices convert heat directly into electricity, or conversely provide localized cooling/heating by absorbing electricity. This data-file screens leading companies in thermoelectrics, their product specifications, applications and underlying calculations for thermoelectric efficiency.

Costs of biogas upgrading to biomethane?
Costs of biogas upgrading into biomethane are estimated at $7/mcf off of capex cost of $400/ton, in this data-file. The largest contributor to total costs is carbon filtering, to remove siloxanes, VOCs and H2S, which we have modelled from first principles, at $2/mcfe. Underlying data into biogas compositions and impurities are also tabulated for reference.

Gas power: levelized costs of combined cycle gas turbines?
Levelized costs of combined cycle gas turbines are built up in this data-file. Our base case costs of gas-fired power generation are 8c/kWh, at a combined cycle turbine converting 55% of the thermal energy of natural gas into electrical energy, for a total CO2 intensity of 0.35 kg/kWh.

Fuel costs and CO2 intensities?
We have produced a cross-plot of the costs and CO2 intensities of different fuels, in $/boe and kg of CO2 per boe, to compre the relative attractiveness of decarbonization options. Favored decarbonization options are nature based solutions, CO2-EOR, blue hydrogen and coal-to-gas switching.

CO2 capture: a cost curve?
This data-file summarizes the costs of capturing CO2. The lowest-cost options are to access pure CO2 streams that are simply being vented at present. Next are blue hydrogen, steel and cement, which could each have GTpa scale. Power stations place next, at $60-100/ton. DAC is carbon negative but expensive.

European shale: an overview?
Europe has 15 TCM of technically recoverable shale gas resources. This data-file aims to provide a helpful overview, as we expect exploration to re-accelerate. Ukraine has the best shale in Europe, which may even be a motivation for Russian aggression. Other countries with good potential, held back only by sentiment are Romania, Germany, UK, Bulgaria…

Offshore vessels: fuel consumption?
This database tabulates the typical fuel consumption of offshore vessels, in bpd and MWH/day. We think a typical offshore construction vessel will consume 300bpd, a typical rig consumes 200bpd, supply vessels consume 150bpd, cable-lay vessels consume 150bpd, dredging vessels consume 100bpd and medium-sized support vessels consume 50bpd. Examples are given in each category, with typical…

Aluminium producers: company screen?
Leading aluminium producers are reviewed in this data-file, across ten companies, producing half of the world’s global output. Scale ranges 1MTpa to 7MTpa. CO2 intensity of primary aluminium production ranges from 3 tons/ton to 17 tons/ton, in aggregate across these companies.
