Northern Lights CCS: the economics?
We have modeled out simple economics for Northern Lights, the most elaborate CCS scheme proposed by the energy industry (Equinor, Shell, TOTAL). The project involves capturing 1.3-1.5MTpa of industrial CO2, shipping it, piping it 110km offshore, then injecting it 3,000m below Norway’s seabed. Costs are expensive. But phase 2 could benefit from scale, offering “CO2…

LNG liquefaction: the economics?
This model captures the economics for a typical LNG liquefaction project, breaking down IRRs and NPVs as a function of key input-variables. In our base case, a new LNG project costing $750/Tpa must charge a $3.6/mcf liquefaction spred for a 10% IRR.

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.

CO2 Emissions from Working?
This model helps you estimate the CO2 emissions associated with working, as a function of 30 input variables. The average CO2 footprint is estimated at 10T per person per year (which could currently be offset for c$150) within a possible range of c5-50T.

Fuel Cell Power Project Economics
This data-file models the economics of constructing a new fuel-cell power project: generating electricity from grey, blue or green hydrogen. The model is based on technical papers and past projects around the industry. Economics look challenging. Our base case estimate is a 24c/kWh incentive price.

Plastic products: energy and CO2 intensity of plastics?
The energy intensity of plastic products and the CO2 intensity of plastics are built up from first principles in this data-file. Virgin plastic typically embeds 3-4 kg/kg of CO2e. But compared against glass, PET bottles embed 60% less energy and 80% less CO2. Compared against virgin PET, recycled PET embeds 70% less energy and 45%…

Carbon Funds to Decarbonize Natural Gas
Natural gas can be decarbonized for a $1/mcf premium, which is used to seed new forests. Attractive cash flows and economics are modelled here. c50% of the carbon premia are dedicated to a carbon fund. It guarantees future CO2 obligations, optimizes emissions reductions, and finally disburses remaining funds.

Working remotely: the economics, the opportunity?
The economic benefits of working remotely are between $5-16k per employee per year, as modelled in shit data-file. Hence we quantify that remote work could step up to displace 30% of all commutes from a typical developed world economy by 2030. The conclusions are substantiated using US data.

Direct air capture of CO2: the economics?
We model Direct Air Capture of CO2 is likely to cost $150-300/ton, based on granular data on its capex, opex and energy-intensity. This data-file outlines the process, our key conclusions, and allows you to stress-test your own input assumptions.

CO2 disposal in geologic formations: the economics?
Costs of disposing of CO2 are extremely variable and project-dependent, ranging from $5-50/ton, with a base case of $22.5/ton. This is the disposal price needed to earn a 10% post-tax IRR, transporting, injecting and monitoring CO2 in the subsurface.
