  • Heavy truck costs: diesel, gas, electric or hydrogen?

    Heavy truck costs: diesel, gas, electric or hydrogen?

    Heavy truck costs are estimated at $0.14 per ton-kilometer, for a truck typically carrying 15 tons of load and traversing over 150,000 miles per annum. Today these trucks consume 10Mbpd of diesel and their costs absorb 4% of post-tax incomes. Electric trucks would be 20-50% most costly, and hydrogen trucks would be 45-75% more, which…

  • MIRALON: turquoise hydrogen breakthrough?

    MIRALON: turquoise hydrogen breakthrough?

    MIRALON is an advanced material, being commercialized by Huntsman, purifying carbon nanotubes from the pyrolysis of methane and also yielding turquoise hydrogen. This data-file reviews MIRALON technology, patents, and a strong moat. Our model sees 15% IRRs if Huntsman reaches a medium-term cost target of $10/kg MIRALON and $1/kg H2.

  • Density of gases: by pressure and temperature?

    Density of gases: by pressure and temperature?

    The density of gases matters in turbines, compressors, for energy transport and energy storage. Hence this data-file models the density of gases from first principles, using the Ideal Gas Equations and the Clausius-Clapeyron Equation. High energy density is shown for methane, less so for hydrogen and ammonia. CO2, nitrogen, argon and water are also captured.

  • Pressure swing adsorption: energy economics?

    Pressure swing adsorption: energy economics?

    Pressure swing adsorption purifies gases according to their differing tendencies to adsorb onto adsorbents under pressure. Pressure swing adsorption costs $0.1/kg when separating pure hydrogen from reformers, and $2-3/mcf when separating bio-methane from biogas. Our cost breakdowns include capex, opex, maintenance, zeolite replacement, compression power and CO2 costs.

  • Transporting green hydrogen as ammonia or toluene?

    Transporting green hydrogen as ammonia or toluene?

    Green hydrogen could be converted into ammonia, shipped like LPGs, then cracked back into green hydrogen in a developed world country. The best case costs are around $10/kg, while generating an IRR of 10%, with full, round-trip energy efficiency of c60%.

  • Plug power: green hydrogen breakthroughs?

    Plug power: green hydrogen breakthroughs?

    Our Plug Power technology review is drawn from the company’s recent patent filings, which offer some of the most detailed disclosures we have ever seen into the manufacturing of PEM electrolysers and fuel cells, underlying catalyst materials, membranes and their manufacturing. One patent seems like a breakthrough. Other patents candidly presented challenges.

  • US Refinery Database: CO2 intensity by facility?

    US Refinery Database: CO2 intensity by facility?

    This US refinery database covers 125 US refining facilities, with an average capacity of 150kbpd, and an average CO2 intensity of 33 kg/bbl. Upper quartile performers emitted less than 20 kg/bbl, while lower quartile performers emitted over 40 kg/bbl. The goal of this refinery database is to disaggregate US refining CO2 intensity by company and…

  • Green hydrogen trucks: delivery costs?

    Green hydrogen trucks: delivery costs?

    We have modelled full-cycle economics of a green hydrogen value chain to decarbonize trucks. In Europe, at $6/gallon diesel, hydrogen trucks will be 30% more expensive in the 2020s. They could be cost-competitive by the 2040s. But the numbers are generous and logistical challenges remain. Niche adoption is more likely than a wholesale shift.

  • Gas pipelines, CO2 pipelines, hydrogen pipelines?

    Gas pipelines, CO2 pipelines, hydrogen pipelines?

    This model captures the energy economics of a pipeline carrying natural gas, CO2 or hydrogen. It computes the required throughput tariff (in $/mcf or $/kg) to earn a 10% IRR. Hydrogen tariffs must be 2x new gas pipelines and 10x pre-existing gas pipelines. CO2 disposal is more economic at scale.

  • Hydrogen: lost in transportation?

    Hydrogen: lost in transportation?

    Transporting hydrogen will be more challenging than any other energy commodity ever commercialised. This 19-page note reviews the costs and complexities of cryogenic trucks, pipelines and chemical carriers (e.g., ammonia). Midstream costs will be 2-10x higher than natural gas, while up to 50% of hydrogenโ€™s embedded energy may be lost in transit.
