Enhanced geothermal: technology challenges?
…heat and power, without geological/exploration risk. The closed loop system does not use hydraulic fracturing, does not exchange fluids with the formation, and thus does not suffer a risk of…
Electric vehicle charging: the economics?
This data-file models the economics of electric vehicle chargers. First, we disaggregate costs of different charger types across materials, electronic components, labor, permitting, fees, opex and maintenance (below). $599.00 – Purchase Checkout…
Proton exchange membrane fuel cells: what challenges?
…and the economics of hydrogen fuel cell vehicles (2x most costly than conventional vehicles per km, note here) and hydrogen fuel cells for power generation (10x more costly, note here)….
China: can the factory of the world decarbonize?
…industrial complex consumes more energy than the entire USA. China’s textile manufacturing industry alone consumes more energy than the entire power grid of Spain. We provide data by major sector…
Vertical greenhouses: the economics?
…flexibility to power grids. Vertical greenhouses could become carbon negative, if they are >75% powered by renewables, and increase yields per acre by c300x, as claimed by some CO2 enrichment…
Wind and solar capacity additions?
…technical papers. Bottlenecks that need to be overcome to reach these incredible growth numbers are not considered in the file, but in our other research, into metals, materials and power…
Cryogenic air separation: costs and energy economics?
This data-file calculates the costs of cryogenic air separation units, which are important in the production of industrial gases, ammonia, metals, materials, medical applications and new energy technologies such as…
Carbon accounting: philosophical investigations?
…in considering the relative CO2 fluxes that can be achieved with 1MWH of renewables (displacing coal power is best, conversion to hydrogen is materially worse) or 1kg of waste biomass…
Forest fires: what climate conclusions?
…more constructive on biomass power, in small quantities, where the burned material comes unequivocally from forest debris, which might otherwise exacerbate the risk of fires. But it is still debatable….
Aluminium production: energy economics?
…lower power prices, no landfill taxes, no CO2 prices and reasonable opex. A more challenging set of environmental standards can literally double the requisite aluminium price. This illustrates a key…
