Fossil fuels

Source: BP Statistical Review 2022, published by Visual Capitalist January 31, 2023 Coal Production If all the coal produced in 2021 were arranged in a cube, it would measure 2,141 meters (2.1km) on each side—more than 2.5 times the height of the world’s tallest building. China produced 50% or more than four billion tonnes of … Les mer

Sol i Sahara

Det dukker fra tid til annen opp tullete tegninger av små frimerker i Afrika, for å illustrere hvor lite som skal til for å dekke verdens energi-behov med solceller. La oss regne på det. Vi tar utgangspunkt i verdens tredje største solcellepark: Pavagada Solar Park i India. The 400MW/1,6GWh Moss Landing Energy Storage Facility er … Les mer

Havvind i Norge

I 2023 går startskuddet for norsk satsning på havvind. Det er snakk om to områder: NVE anslår 30 millioner / MW for faste og 50 millioner / MW for flytende vind. energimeldingen som den norske regjeringen la frem, er NVE sitert på at bunnfast havvind på Sørlige Nordsjø II kan bygges med en levetidskostnad (LCOE) … Les mer

Biosphere 2

Could humans maintain an ecosystem on the Moon or Mars? In 1991, 8 researchers locked themselves inside this 3.14-acre sealed structure in the Arizona desert for 2 years to test just that. It remains the largest and longest experiment of its kind, ever.Biosphere 2 was built to be an isolated, self-sufficient ecosystem, modelled after the … Les mer

Realpolitik

Alexander Stahel My view: unless the West get its decarbonisation targets & deadlines in line with China (& India), reducing CO2 is 100% risk and 0% reward. What drives policy? In short: @IPCC_CH. Scientists there believe an increase of 1.5C is the “safe limit” for global warming while higher temperatures may change the environment and, … Les mer

Energikommisjonens optimisme

Energikommisjonen la fram rapporten sin i februar 2023. Den handler ikke om konkrete prosjekter, men beskriver 40TWh ekstra som realistisk i løpet av de neste sju årene. La meg forsøke å tegne et bilde av hva det er: Statnett sier: Motstanden mot vindkraftutbygging på land og begrenset potensial for vann- og solkraft, gjør at havvind … Les mer

SAF – sustainable aviation fuel

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

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 (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
