…Wh/kg, while batteries today are 250 Wh/kg and will at best reach 1,250 Wh/kg (data here). We have evaluated sustainable aviation fuels, such as renewable jet, biogas-to-liquids, bio-ethanol-to-jet and e-fuels,…
How will food and energy shortages re-shape liquid biofuels? This 11-page note explores four questions. Could the US re-consider its ethanol blending to help world food security? Could rising cash…
…market sizing looks industry-by-industry, to break down possible capture volumes. We discuss each industry in turn – coal power, gas power, ethanol, steel, cement, et al., – on pages 9-12….
…from biomass is likely c30% lower in CO2 than conventional plastics, but around 2x more costly (research note here). The economics of the ethanol-to-ethylene chemical pathway are modelled here. Biomass-derived…
…facility, to understand whether CCS can ‘take the edge off’? Our conclusions are that many coal plants may be ‘too large’ to decarbonize with CCS, whereas many ethanol plants are…
…electro-reducing CO2 into C2s, such as ethylene, which is the chemical precursor to polyethylene [1]. The process has a Faradaic efficiency of 80%. It yields two-thirds ethylene, one-third ethanol, and…

…of US cropland is tied up in producing ethanol. Controversies and debates? Time for a humility moment. This model reflects our best estimates after 15 years of energy analysis, and…
…sources. For example propane boils at -42°C, methanol boils at 65°C and ethanol at 78°C. Past systems have historically also used fluorocarbons. Organic Rankine Cycles can be useful for waste…
