Global CO2 emissions breakdown?
Global CO2 emissions rose from 32GTpa of CO2-equivalents in 1990 to 54GTpa in 2024, and are seen optimistically declining to 30GTpa by 2050, on a gross basis. This global CO2 emisisons breakdown covers 33 sources that each explain over 0.5% of global CO2e emissions, as a way of tracking emissions by source, by year, and…

Oxycombustion: economics of zero-carbon gas?
Oxy-combustion is a next-generation power technology, burning fossil fuels in an inert atmosphere of CO2 and oxygen. It is easy to sequester CO2 from its exhaust gases, helping heat and power to decarbonise. We argue that IRRs can be competitive with conventional gas-fired power plants.

Chemical Looping Progress?
Chemical Looping Combustion could clean up future coal or gas-fired power. But will it work? We have tabulated data from the technical literature on 40 chemical looping combustion pilots. They have run collectively for 10,000 hours. They promise 38% energy efficiencies for zero carbon emissions.

Energy Transition Technologies?
This data-file “scores” the top technologies to transform the global energy industry and the world, as assessed by Thunder Said Energy. Each one is scored based on technical readiness, economic impact and the level of work we have conducted.

The World’s Great Gas Fields and Their CO2
This data-file tabulates 30 major gas resources around the world, their volumes, their CO2 content and how the CO2 is handled. This matters because higher CO2 gas fields are more costly to develop into LNG, while CO2 venting is no longer acceptable without CCS. Permian & Marcellus LNG are best positioned.

Decarbonized gas: ship LNG out, take CO2 back?
This note explores an option to decarbonize global LNG: (i) capture the CO2 from combusting natural gas (ii) liquefy it, including heat exchange with the LNG regas stream, then (iii) then send the liquid CO2 back for disposal in the return journey of the LNG tanker. There are some logistical headaches, but no technical show-stoppers.…

Decarbonizing global energy: the route to net zero?
The global energy system can be fully decarbonized by 2050, for an average CO2 cost of $42/ton. Remarkably, this is almost half the cost foreseen one year ago. 85Mbpd of oil and 375TCF pa of gas are still required in this 2050 energy system, together with efficiency technologies, carbon capture and offsets.

Ethane cracking: the economics?
This data-file captures the economics of ethane-cracking to produce ethylene. A typical US Gulf Coast facility could generate 15% IRRs at typical capex cost of $1,135/Tpa. CO2 intensity can be as high as 1.7T of CO2 per ton of ethylene, or potentially much lower depending on the facility’s energy efficiency.

Cost and CO2 intensity of home cooking technologies?
The most important determinant of cooking’s CO2 intensity is consumer behaviour. At today’s energy costs and grid mix, gas-fired cooking yields the lowest costs. Sometimes electrification of cooking will decrease CO2 and sometimes not. Electric induction is most efficient, but 2-3x more expensive than gas and electric hobs.

Drone companies: OEMs, inspection, defense and delivery?
This data-file is a screen of 40 leading drone companies, which either manufacturing drones for consumer, commercial and defense purposes; offer drone inspection services; or offer drone delivery services. It is a vibrant landscape, with over half of the companies founded after 2010, worth c$40bn pa, and creating c$120bn pa of economic benefits.
