Nature-based CO2 removals: a summary?
This data-file aggregates the details of different nature-based CO2 removals projects that we have been supporting at Thunder Said Energy. The average nature-based reforestation initiative that we supported in 2022 scored 70/100 on our framework. Statistical details and distributions are explored.

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.

NET Power: gas-fired power with inherent CO2 capture?
Our NET Power technology review shows over ten years of progress, refining the design of efficient power generation cycles using CO2 as the working fluid. The patents show a moat around several aspects of the technology. And six challenges at varying stages of de-risking.

Boston Metal: molten oxide electrolysis of steel?
Boston Metal aims to decarbonize steel, using molten oxide electrolysis, absorbing 4MWH/ton of steel. This data-file is a Boston Metal technology review, based on assessing 55 patents across 3 families. We were unable to de-risk the technology. A key challenge is conveying current into the cell, as it operates around 1,600C, which is above the…

Diesel power generation: levelized costs?
A multi-MW scale diesel generator requires an effective power price of 20c/kWh, in order to earn a 10% IRR, on c$700/kW capex, assuming $70 oil prices and c150km trucking of oil products to the facility. Economics can be stress-tested in the Model-Base tab.

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.

MHI CCS technology: performance, costs and emissions?
MHI has deployed an amine-based CO2 capture technology, in 15 plants globally, going back to 1999. Reboiler duties are around 2.6 GJ/ton on a 10% CO2 feed. Capture rates and capture purity are high. Degradation and amine emissions are controlled, and c80-90% below MEA. CCS costs and complexities remain high. In our view, this is…

Offshore wind: levelized costs?
This model estimates the levelized cost of offshore wind at 13c/kWh, to generate a 7% IRR off of capex costs of $4,000/kW and a utilization factor of 40-45%. Each $400/kW on capex adds 1c/kWh and each 1% on WACC adds 1.3 c/kWh to offshore wind levelized costs.

Plug power: green hydrogen breakthroughs?
Our Plug Power technology review is drawn from the company’s recent patent filings, which offer some of the most detailed disclosures we have ever seen into the manufacturing of PEM electrolysers and fuel cells, underlying catalyst materials, membranes and their manufacturing. One patent seems like a breakthrough. Other patents candidly presented challenges.

Energy transition: ten positive themes?
It can feel gloomy, forecasting 2-6% global energy shortages, bottlenecks on material value chains that must scale by 3-30x, and even fearing that global conflicts will volatilize commodity prices. Yet there are ten themes that particularly excite us, presented here, from faster technology progress, to world-changing efficiency technologies and a new age of ‘advanced materials’.
