""We need new nuclear to deliver a golden age of clean energy abundance," energy secretary Ed Milliband said at the time of the investment's announcement, "because that is the only way to protect family finances, take back control of our energy, and tackle the climate crisis."
The idea that nuclear will solve all of our problems, has to be challenged. Nuclear does not address the now out of control heat input to the planet from the ongoing use of heat engines to create energy, particularly electricity. Net zero argues that the overall problem is that the heat entering our atmosphere during daylight hours is retained by carbon dioxide CO2 gas at 400+ ppm, so the first thing to describe is something that has long been well known in the glasshouse industry, that increasing the CO2 input to the plant growth area inside the glasshouse both increases the quantity of plant product, and in doing so, dramatically reduces the level of CO2 within the glasshouse. The growing plants adsorb the CO2; for example you can find detailed research that shows during daylight, the adsorption in fact reduces CO2 by half. That the early morning level of 400 ppm reduces to ~200 ppm during daylight hours, and it is not until the sun sets, (and the greenhouse temperature reduces back to night time temperatures), that the CO2 levels retain their 400 ppm level. Just this simple example clearly demonstrates what is a fatal (for the planet), flaw in the concept of net zero; that there is insufficient CO2 within the planet atmosphere during daylight to retain the heat of the day.
Then we need to turn to another aspect of this debate, the sun only shines upon the area of the planet during daylight; so for two thirds of the rotation of the planet the heat reduces as the CO2 increases.
When we look at an century old technology of the power station, of creating heat, with coal, oil, gas, nuclear or even fusion, we observe water being boiled to produce very high pressure steam which drives the turbine to drive the electricity generator; which creates waste steam at a lower pressure and temperature which has to be condensed back to water to be returned to the boiler to create more steam. That is a "Heat Engine", no different to the same technology driving all fossil fuel burning vehicles. We know a lot about the development of heat engines, where for example the heat efficiency of a well managed coal fired power station, is much better than a nuclear powered power station, where the latter has to add the need to keep cool the nuclear pile; but it is generally accepted that ALL such power stations have to remove more than 60% of the heat generated as waste heat, either into the atmosphere, or by pumping water from the surrounding sea to cool the waste steam back to water. For example the new nuclear power plants being built at Hinkley Point in Somerset in the UK need a huge diameter tunnel, 2.8 miles long to deliver 120,000 litres per second of warm water, ~12 Degrees warmer than the input temperature, back out into the surrounding sea. For every 1GW of electricity generated, ~ 2.8 GW of heat is delivered back into the sea. Very importantly, not during daylight hours, but continually 24 hours of each day for the next 60 years.
Now understand that these power station heat engines are the cause of rapidly growing air and sea temperatures; particularly sea temperatures which are driving the rapid increase in dramatic episodes of severe rainfall; rain that stems from the higher sea temperatures creating equally rapid increases in evaporation of the sea surface which drive the increase in rainfall.
So going nuclear is not going to do anything about the heat generated by power stations. that our problem is the strange belief of those suggesting the solution is the reduction of CO2, when there is no debate about the heat source, and about the simple well known fact that during daylight, CO2 decreases due to adsorption by plant life.
All of us are facing the need to stop the use of ANY form of heat engine to create an energy source; or completely lose control of the climate of the planet.
Please think about that when next time there is a report about a massive rain storm destructively washing through a town or city; or again when the air temperature reaches the point where we humans cannot survive, and forest fires burn all surrounding surface plant growth.
We have no option; we must stop the use of heat engines. Period!
