Electric vehicles: the road to cost parity?
Could electric vehicles deflate towards cost parity with ICEs in 2025-30, helping to re-accelerate EV adoption? This 13-page report contains a granular sum-of-the-parts cost breakdown for EVs vs ICEs. Then we consider battery deflation, power train deflation, small urban EVs, tax incentives, and the representativeness of low-cost Chinese EVs.

Electric vehicles: saturation point?
Energy transition technologies are often envisaged to follow S-curves: rapidly inflecting, then reaching 100% market adoption. However, this 17-page report argues electric vehicles will more likely saturate at 15-30% of sales in 2025-30. EVs were already at 15% of sales in 2023. So what would the more limited EV upside mean for energy and materials?

Purchasing power: what are generation assets worth?
There has never been more controversy over the fair values of power generation assets, which hinge on their remaining life, utilization, flexibility, power prices, rising grid volatility and CO2 credentials.

Oil demand: making millions?
What does it take to move global oil demand by 1Mbpd? This 22-page note ranks fifteen themes, based on their costs and possible impacts, to show where risks lie for oil markets, and where opportunities are greatest to drive decarbonization. We still think oil demand plateaus around 105Mbpd mid-late in the 2020s, before declining to 85Mbpd by 2050. But the risks now lie to the upside?

Natural hydrogen: going for gold?
Vast quantities of hydrogen are produced in the Earthโs subsurface, via the serpentinization of iron-containing Peridotite rocks. Gold, white and orange hydrogen variations aim to harness this hydrogen.

Methane leaks: by gas source and use
Methane leakage rates in the gas industry vary by source and use. Across our build-ups, the best-placed value chains are using Marcellus gas in CCGTs (0.2% methane leakage, equivalent to 6kg/boe, 1kg/mcfe, or +2% on Scope 3 emissions) and/or Permian gas in LNG or blue hydrogen value chains (0.3%). Residential gas use is likely closer to 0.8-1.2%, which is 4-6kg/mcfe, or higher as this is where leaks are most likely under-reported.
