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.

Solar water heaters: the economics?
Under our base case estimates, a $130/ton CO2 price is required to achieve passable economics and incentivize rooftop solar heaters. Once installed, solar heaters save around 1T of CO2 per household per year and lower water heating bills by 50-80%. This data-file models the economics.

Biomass to biofuel, or biomass for burial?
Greater decarbonization at a lower cost is achievable by burying biomass (such as corn or sugarcane) rather than converting it into bio-ethanol. This model captures the economics. Detailed costs and CO2 comparisons are shown under different iterations.
-
Green hydrogen: the economics?
We have modelled the economics of a green hydrogen project, electrolysing water using renewable energy. An H2 price of $8/kg ($60/mcfe) is required to earn a 10% return. Costs data are captured. The most challenging input variable is not capex cost or efficiency, but utilization rate, if the project is to be truly green.
