Wind and solar getting more expensive - for good reasons

Image
 By Ian Page This is the price asked for a power purchase agreement which is rising because of too much demand! It's reached the dizzy heights of 3.4 cents per KW hour ( Irony- that's still very cheap compared with gas) The cost of producing wind and solar continues downward ( with some hiccoughs due to taxes and supply chain issues) Thus hopefully wind and solar are making more profits and will accelerate investment.

A rather clever engineering innovation to increase solar efficiency while producing heat energy on a roof

Ripple effect of gas prices

by Ian Page Natural gas prices have risen significantly for a complex of reasons. Either this is the long-term trend we anticipate (peak gas supposed to be 2021/22 some years ago) or just one of those things. However, it gives us an insight into the effects. The UK has relatively high gas prices and high volatility since it is at the end of the Russian pipelines and not in the EU - so shortages such as the current Russian reduction in gas supply, are multiplied since other countries take theirs first. There is some North Sea gas left but it’s diminishing. Finally, the UK gets LNG which is more expensive than piped gas normally because of the energy costs of liquefaction, transport cooling and regasification. In addition, one of the largest gas storage systems was closed last year reducing the strategic reserve and increasing volatility of prices As a result, two of the UK's fertilizer plants closed and grid electricity prices are about to rise significantly. (As a lot of the UKs el...

CO2 to ethanol

Image
 by Ian Page https://pubs.acs.org/doi/full/10.1021/jacs.1c03940 To survive we need to turn CO2 into a valuable input to processes (other than enhanced oil extraction and fizzy drinks) rather than something to be just buried to leak later. The more carbon atoms you can get to stick together the higher the value of the resulting products. CO2 to ethanol/ethyl alcohol is one of the critical must do paths but has proved difficult. This study shows that three catalysts, none of which is that good on their own, when put together at the atomic level in a particular way, produce impressive results. Zinc Oxide, copper, and cesium are all relatively available materials for this purpose. The paper probably has more details of the efficiency and yield. At least I hope so! Finding the catalysts and working out how it works involved some heavy cross disciplinary work and advanced tools, however it shows that binary and ternary ca (and perhaps higher) catalyst structures offer a massive field of ...
