Oil and War: ten conclusions from WWII?
…trucks are all highly energy-intensive. For example, a tank achieves a fuel economy of around 0.5 miles per gallon. Thus, Erwin Rommel wrote that “neither guns nor ammunition are of…
Hydrogen: overview and conclusions?
…have evaluated electro-fuels, green methanol, sustainable aviation fuels, hydrogen trucks, again finding CO2 abatement costs above $1,000/ton. Again, we think transportation can be decarbonized cost-effectively via other means. (3) How…
Solid state batteries: will they change the world?
Solid state batteries promise 2x higher energy density than traditional lithium ion, with 3x faster charging and lower risk of fires. Thus they could re-shape global energy, especially heavy trucks….
Energy storage: top conclusions into batteries?
…in long-distance power transmission, decarbonized gas, next-gen nuclear; fully decarbonizing future grids while keeping costs below 10-20c/kWh. (7) Density will improve, but not enough for mass deployment of battery trucks,…
Hydrogen: lost in transportation?
Transporting hydrogen will be more challenging than for any other commodity ever commercialised in the history of global energy. This 19-page note reviews the costs and complexities of cryogenic trucks,…
Energy Technologies and Energy Transition
…They can be revolutionary. Heavy vehicles will remain fossil-fuelled with energy savings from hybridization. Green hydrogen trucks: delivery costs? (Jul-2020, 18-pages) Remote possibilities: working from home? (Mar-2020, 21-pages) Electric Vehicles…
US Vehicle Fleet: fuel economy, masses and vehicle types?
…2022 The vehicle mix has also shifted away from small and efficient sedans towards larger and less efficient SUVs and trucks. The average vehicle has grown from 1.4 tons at…
Vehicle fleets: service life and retirement age by vehicle type?
…expected for buses and heavy trucks, at c15-years, while the longest service lives are expected for new planes, ships and trains at 25-35 years. The longest-lasting vehicles in our data-set…
The Ascent of LNG?
…there further upside? One might expect, in an overview of LNG technologies, to find incremental upside in road vehicles: either directly in LNG-fired trucks, in gas-fired vehicles, or to produce…
Vehicles: fuel economy and energy efficiency?
Vehicle fuel economy and energy efficiency are quantified in this data-file, looking across different transportation types: cars, trucks, buses, hybrids, electric vehicles (EVs), hydrogen cars, planes, trains, helicopters, plus other…
