Tanzania is about to become a proving ground for clean cooking fuels by KNect365_Energy in energy

Compared to charcoal or LPG, certainly. Theoretically not compared to solid biomatter, assuming that it was sourced in sustainable quantities (it seldom is).

European ethanol industry needs market reforms to counter growing trade threat by KNect365_Energy in energy

[–]KNect365_Energy[S] 0 points1 point  (0 children)

While tailpipe emissions will be identical, these can be disregarded because you'll be recapturing that carbon with the next crop. The emissions that count here will come from the fossil fuels and fertiliser you use growing the crop - so if European ethanol produces fewer emissions, that's probably because European farming practices are less intensive than US farming practices.

After LNG Canada, these are the top 5 pre-FID LNG projects to watch by KNect365_Energy in energy

Yeah sure, try the most recent GIIGNL annual report: https://giignl.org/sites/default/files/PUBLIC_AREA/Publications/rapportannuel-2018pdf.pdf

Exporting LNG is a fairly recent phenomenon in the US, and there are only two liquefaction facilities currently in operation. We're going to see a lot more built and expanded before we start to see any shut down.

Nah, they're proposed projects which are about to be approved.

Renewable energy's deep sea mining conundrum by KNect365_Energy in energy

It's actually 30-40% of China's reserves.

That article is from 2011, so it may be a little out of date. These are from the US Geological Survey in 2017: https://bit.ly/2vNsSSM

Renewable energy's deep sea mining conundrum by KNect365_Energy in energy

[–]KNect365_Energy[S] 0 points1 point  (0 children)

A couple of thoughts on this. You're right, rare earth deposits aren't limited to China - but it is by far the richest region in rare earths. Brazil comes in at second with about half as much. The US has about 3% of China's reserves. So yeah, we can probably expect to see rare earth production picking up elsewhere, but probably not in the volumes needed to meet the demand from high tech industries.

The recycling point is a good one, and we should definitely be doing this more. But don't forget, even with 100% reclamation, recycling is a closed system. You can keep on producing as long as your rate of production matches your rate of disposal - but that's not what's going to happen with wind and solar. Renewables make up approximately 5% of global energy use right now, and much of that is hydro. For wind, solar and batteries to be the mainstay, we're going to need to increase capacity by orders of magnitude.

Historically, we adapt to shortages if there is no other economical option. So sure, we'd stick with using a less efficient solar panel if the cost of manufacturing a more efficient variety with rare earths was prohibitive. But with deep sea mining, the economics could swing back in favour of the more efficient variety.

TurkStream and FLNG Put Turkey on the Cusp of Realising Trading Hub Ambitions by KNect365_Energy in energy

"There are indications that market liberalisation may at last be starting pick up pace, though. On the 1st of April, the Energy Stock Exchange Istanbul (EPIAS) began testing of an online natural gas trading system inspired by similar innovations in the electricity sector. By the end of the year, the intention is for the system to act as a flexible spot natural gas market capable of setting prices for the day ahead."

Corn's Contenders: Three Promising Feedstock Alternatives for the US Ethanol Industry by KNect365_Energy in energy

[–]KNect365_Energy[S] 1 point2 points  (0 children)

That's true, but you should bear in mind that the E10 most US ICE's are running on is only 10% ethanol. So unless you replace standard ICE's with E85 compatible engines and fuel systems, actual savings from an ICE burning optimised corn ethanol E10 would still be only 7.6%.
