Mitigating methane: what methods?

This data-file screens the methods available to monitor for methane emissions. Notes and metrics are tabulated for Method 21, Optical Gas Imaging, fixed sensors, ground labs, aircrafts, drones and satellites; including advances at the cutting edge of each method.

Emerging screening methods, such as drones and trucks are also scored, based on results from an excellent recent technical trial. The best drones can detect almost all methane leaks >90% faster than traditional methods.

Companies developing next-generation methane-mitigation technologies are screened, including 11 public  companies and 33 private companies. This peer group filed 150 patents in 2018-19. 8 companies seem particularly exciting to us.

Operators are also screened, across the dozen largest Energy Majors, to estimate their methane leaks and broader methane intensity across the supply chain.

Value in Use: CO2 intensities of household items?

We estimate costs and carbon intensities per use for twenty low-utilisation household objects: the average is $13 per use and 1.3kg of CO2, respectively. Both are high numbers.

The biggest determinant is the number of uses per item.  We fear that once purchased by a consumer, the average item on our list will be used just c20 times in its entire lifetime.

More extensive “sharing” will be enabled by drone delivery technologies, potentially saving $150bn of annual sales and 15MTpa of CO2 emissions across these 20 items items alone. Across the entire US economy the savings could reach $1trn and 100MT per year.

Distribution Costs: Ships, Trucks, Trains and Delivery Vans?

This data-file breaks down the financial and carbon costs associated with a typical US consumer’s purchasing habits. It covers container-ships, trucks, rail freight, cars and last-mile delivery vans; based on the ton-miles associated with each vehicle and its fuel economy.

We estimate the distribution chain for the typical US consumer costs 1.5bbls of fuel, 600kg of CO2 and $1,000 per annum.

The costs will increase 20-40% in the next decade, as the share of online retail doubles to c20%. New technologies are needed in last-mile delivery, such as drones.

Drones attack military fuel economy?

This data-file quantifies the fuel economies of typical military vehicle-types, as $1.7 trn per annum of global military activity consumes c0.7Mbpd of total oil demand on our estimates, which are also included in the data-file.

Military drones  are transformational. Almost all the incumbent military vehicles in our data-file have fuel economies below 1 mpg. But the Reaper and Predator drones, famous for their deployment in recent conflicts, have achieved 3mpg and 8mpg respectively. But small, next-generation electric drones will achieve well above 1,000 mpg-equivalent.

Swarms of small-scale electric drones could emerge as the most devastating military weapon of the 21st century, according to a book we read last year on the topic, arguing that “A swarm of armed drones is like a flying minefield…they are so numerous that they are impossible to defeat… each one presents a target just 4-inches across… and shooting down a $1,000 drone with a $5,000 missile is not a winning strategy”. Our notes on the book are included in the data-file.
