US decarbonization: energy and CO2 emissions?
The US consumes 25,000 TWH of primary energy per year, which equates to 13,000 TWH of useful energy, and emits 6GTpa of CO2. This model captures our best estimates for what a pragmatic and economical decarbonization of the US will look like, reaching net zero in 2050, with forecasts for wind, solar, nuclear, hydro, oil,…

Natural gas: the EU green taxonomy’s 270g/kWh CO2 target?
The EU taxonomy is a set of guidelines that label some investments as ‘green’. This includes gas power with a CO2 intensity below 270g/kWh. Most conventional gas projects will not meet this hurdle, but CHPs and 20-30% blends of lower-carbon gas could accelerate.

CH4 context: the largest methane leaks of all time?
Global methane emissions run to 360MTpa. 40% is agriculture, 40% is the energy industry and 20% is landfills. Within energy, over 30% of the leaks are from coal, 30% are from oil, 27% are from gas. This short note quantifies some of the largest methane leaks of all time, and provides context for the recent…

Electrostatic precipitator: costs of particulate removal?
Electrostatic precipitator costs can add 0.5 c/kWh onto coal or biomass-fired electricity prices, in order to remove over 99% of the dusts and particulates from exhaust gases. Electrostatic precipitators cost $50/kWe of up-front capex to install. Energy penalties average 0.2%. These systems are also important upstream of CCS plants.

Nature based solutions to climate change?
Nature based solutions are likely to deliver c20-25% of the decarbonization in a realistic roadmap to net zero. Reforestation is low-cost (c$50/ton), technically ready, convenient and helps nature. Key challenges are improving the quality of nature-based CO2 removals and accelerating momentum. We see upside for companies that can clear these hurdles. Our top ten conclusions…

Biofuel technologies: an overview?
Biofuels are currently displacing 3.5Mboed of oil and gas. But they are not carbon-free, and their weighted average CO2 emissions are only c50% lower. This data-file breaks down the biofuels market across seven key feedstocks, to help identify which opportunities can scale for the lowest costs and CO2, versus others that require further technical progress.

MIRALON: turquoise hydrogen breakthrough?
MIRALON is an advanced material, being commercialized by Huntsman, purifying carbon nanotubes from the pyrolysis of methane and also yielding turquoise hydrogen. This data-file reviews MIRALON technology, patents, and a strong moat. Our model sees 15% IRRs if Huntsman reaches a medium-term cost target of $10/kg MIRALON and $1/kg H2.

Turn the Plastic Back into Oil
Due to the limitations of mechanical recycling, 85% of the world’s plastic is incinerated, dumped into landfill, or worst of all, ends up in the oceans. An alternative, plastic pyrolysis, is on the cusp of commercialisation.
