Batteriteknologi

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. Flow battery Flow batteries could emerge as a breakthrough technology for stationary storage as they do not show performance degradation for 25-30 years and are capable of … Les mer

We will destroy the earth in the name of «Green Energy» Follow along and I will explain. MiningWatch Canada is estimating … Les mer

Mining our way to energy transition

Vi trenger 4,5 milliarder tonn kobber, seks ganger alt kobber vi hittil har gravd ut. Det er også fem ganger mer enn de kjente reservene og med dagens kapasitet for kobberutvinning vil det ta 190 år. Dette tar ikke inn at man også må utvide overføringsnettet. Det er kun snakk om kraftkildene, og det er … Les mer

Syntetisk drivstoff

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

No plans

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.

Green hydrogen

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

The four pillars of modern society

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. It was estimated that the cement manufacturing … Les mer

Karbonfangst

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

What, if Anything, is Wrong with Extreme Wealth?

Ingrid Robeyns 1. Introduction Over the past decades, scholars have shown that economic inequalities are widening. Perhaps best-known of all is the work of Thomas Piketty (2014), who showed that disparities in wealth have been increasing in many countries, due to the improvement of the financial position of the 1% best off or more specifically … Les mer

Hvor langt kommer vi

Solar and wind energy are notably expected to play a major role in this decade, accounting for up to a third of emission reductions. Net zero by 2050 scenarios from the IEA, IRENA and BP all agree that installed solar and wind capacities must be close to About 200 GW of new solar PV and … Les mer
