LNG liquefaction technologies: an overview?
…total power rating, while a project launched by Equinor in 2022 will add a 420kV power line to supply this load from Norwegian hydro and reduce Norway’s total annual emissions…
Wind: aim higher?
This data-file contains a simple model for how wind speeds and wind power co-vary with altitude. 2x greater power could likely be harnessed by a kite at 300m than a…
Chemical Looping Progress?
Chemical Looping Combustion is a next-generation technology for carbon capture, with potential to “clean up” fossil fuel power and obviate CO2 emissions. Costs and energy penalties are dramatically lower than…
Shipping in batteries: the economics?
What if it were possible to displace diesel from high-cost, high-carbon “island” electricity grids, by charging up large batteries with gas- and renewable power, then shipping the batteries? This model…
Heliogen: concentrated solar breakthrough?
Heliogen has set a new record for concentrated solar power in November 2019, generating >1,000C temperatures from an array of c370 hexagonal mirrors, which are precisely controlled using computer vision….
MCFCs: what if carbon capture generated electricity?
…carbon separation technologies, which can be retrofitted to 4TW of pre-existing power plants, without adding $50/T of cost and 15-30% of energy penalties per traditional CCS. Pages 5-13 outline how…
The future of offshore: fully subsea?
…power from shore, fewer materials and the elimination of PSV/helicopter trips. The key engineering challenges for fully subsea systems, which remain to be resolved, are summarized on page 14. Who…
District heating: the economics?
District heating supplies residential or commercial consumers with centrally generated heat, waste heat from power generation (combined heat and power) or from other industrial processes. Capturing waste heat lowers CO2-intensity….
Net zero Oil Majors: worth the cost?
…method to lower Scope 1&2 CO2 emissions is to power c10% of operations with renewables. This will also cost $850/Tpa of CO2 that is saved, based on our economic models…
Green Hydrogen Economy: Holy Roman Empire?
This 16-page note models the green hydrogen value chain: harnessing renewable energy, electrolysing water, storing the hydrogen, then generating usable power in a fuel cell. Today’s end costs are very…
