Ole A contradition in terms? Forbruk i 2022: 7,9 million barrels/day = 1,25 mrd liter/dag = 458 mrd liter/år = 365 mill tonn/år. An estimated 1 billion dry tons of biomass can be collected sustainably each year in the United States, enough to produce 50–60 billion gallons of low-carbon biofuels (= 210 mrd liter/år). 1 tonn jet fuel … Les mer
IEAs Net Zero Emissions scenario anslår at batterikapasiteten vil øke fra 27 (+9 siste år) GW i 2021 til 780 GW i 2030 og 3500 GW i 2050 (3,86 TW egentlig, med 6 h kapasitet = 23,2 TWh). Flow battery Flow batteries could emerge as a breakthrough technology for stationary storage as they do not … Les mer

A plant will use 20 megawatts to produce 8000 tons of transportation fuel per year, This method will avoid producing 28,600 tons of CO2 annually from fossil fuels. 20 MW 24/365 is equivelant to 175 GWh/year. That could power electric cars for 1000 million kilometers or produce enough diesel to power fossile fuel cars 167 … Les mer
The energy transition has no plan – just goals Doug Houseman (Principal Consultant at Burns & McDonnell) about energy storage. Doug is a leader and visionary in grid and utility modernization.
What do we need? According to the International Renewable Energy Agency (Irena), the world will need 19 exajoules of green hydrogen in the energy system in 2050 — between 133.8 million and 158.3 million tonnes a year. Recharge calculations show that producing such a volume would require at least 6,690TWh of dedicated electricity every year … Les mer
These four are responsible for 17% of all energy consumed and 25% of CO2 emissions. Cement 4,4 billion tons A typical modern plant consumes 4 GJ of energy to produce one ton of cement, while the cement production in the world is about 3.6 billion tons per year.

Greit om du kan plukke det fra industri du ikke kan leve uten, men fangst fra friluft er det mest fjollete til dags dato. One run takes about four hours and the process needs ~2,000 kWh of thermal energy and ~650 kWh of electricity to capture one tonne of CO2. The CO2 thus separated from ambient air is also mixed with water and … Les mer
