Compressed air energy storage: costs and economics?
Our base case estimates for Compressed Air Energy Storage costs require a 26c/kWh storage spread to generate a 10% IRR at a $1,350/kW CAES facility, with 63% round-trip efficiency, charging and discharging 365 days per year. Our numbers are based on top-down project data and bottom up calculations, both for CAES capex (in $/kW) and…

Electromagnetic energy: Planck, Shockley-Queisser, power beaming?
Electromagentic radiation is a form of energy, exemplified by light, infrared, ultraviolet, microwaves and radiowaves. What is the energy content of light? How much of it can be captured in a solar module? And what implications? We answer these questions by explaining the Planck Equation and Shockley-Queisser limit from first principles.

Japan oil demand: breakdown over time?
Japan’s oil demand peaked at 5.8Mbpd in 1996, and has since declined at -2.0% per year to 3.4Mbpd in 2023. To some, this trajectory may be a harbinger of events to come in broader global oil markets? While to others, Japan has unique features that do not generalize globally? Hence this report and data-file…

Overview of lasers: by type, market size and efficiency?
The global laser market is worth $20bn pa, of which half comprises diode lasers mainly used for fiber-optic communications and around 30% is fiber lasers mainly used for cutting, welding and heat-treating materials. These two laser types dominate because of their high, 30-80% efficiencies. This data-file is a brief overview of lasers.

Microwave Chemical: electrical heating?
Microwave Chemical is a small-cap company, developing microwave-based heating solutions, across over a dozen use cases, from acrylic recyling, to producing food/cosmetic compounds, to carbon fiber (particularly interesting!). We reviewed a dozen of the company’s patents in this data-file, which is a Microwave Chemical technology review and finds a moat in efficient microwave heating.

Leilac low-carbon cement technology?
This data-file explores Leilac low-carbon cement technology, which separates the calcination stage, within an indirectly heated reactor, so that 98% pure CO2 can be gathered and sequestered, with requiring post-combustion CCS (amines). Patents from parent company, Calix, lock up the technology, with clear and intelligible details, although this also shows where the challenges are.

Ecolab: water management technology?
Water is used in heat exchangers, in data-center cooling and power plant cooling. These are interesting areas, which have featured in our research. But what opportunities to raise performance and lower water use? Ecolab water management technology monitors the composition of industrial water and then optimizes additives against scaling, fouling and corrosion. Recent patents will…

EOG’s Digitization: Pumped-Up?
EOG patented a new digital technology in 2019: a load assembly which can be built into its rod pumps: to raise efficiency, lower costs and lower energy consumption (i.e., CO2). This short note reviews the patent, illustrating how EOG is working to further digitize its processes, maximise productivity and minimise CO2 intensity.

Subsea Services: Patent Leaders?
This data-file captures all the subsea patents from ten of the largest service providers. Priorities have shifted since the oil downturn. The data show who is most innovative and who is best placed, by category. Clear leadership is seen in subsea pumps, wellheads, or umbilicals. Other areas are more competitive.

Methane emissions from pneumatic devices: by operator, by basin?
Methane leaks from 1M pneumatic devices across the US onshore oil and gas industry comprise 50% of all US upstream methane leaks and 20% of upstream CO2. This file aggregates the data. Rankings reveal operators with a pressing priority to replace >100,000 medium and high bleed devices, and other best-in-class companies.
