Hi Mike, thanks for the read. Rather tentative stuff with lots of hidden assumptions about the future, but does suggest that electric are ahead of hydrogen at the moment. These facts have a habit of changing quite suddenly or not progressing as expected, so we are still at the experimental, lets try everything and see what works stage.
Thanks for your interesting comments cc.
One lot of relatives are out for the afternoon and the next lot don't come until tomorrow so I needed something to read!
Electricity storage has long been the problem and no doubt we will continue to make progress, but hydrogen stores the power of electricty, being made by electricity but delivering its stored power by combustion. The real issue is capacity. renewables have made massive inroads into the electricity capacity, but the needed capacity is going to have to trable to replace petrol, diesel and domestic gas over the next couple of decades.
Higher building standards and the retrofitting of old houses and flats with better insulation and draught proofing, particularly in the private rented sector, remains the most cost effective quick win, but unfortunately our present government messed up its programme to do this spectacularly.
And of course in the very long term we may have fusion. In the medium term we need to use a wide range of developing technologies, but I don't think blue hydrogen should be one of them. As we wean ourselves off gas and petrol our electicity generating capacity will need to be expanded several times so there will be lots of gaps to plug. Hydrogen is likely to be used initially in gas pipe networks on the coast within easy reach of offshore wind.
Oil may have a long term future in making plastics but only if biological recycling technologies develop further.
I think we should be putting more resources into wavepower and geothermal at present
Hi Mike, yes I am aware of all the environmental and humanitarian downsides of electric cars. They are an intermediate solution to the problem of global warming, although battery technology may have further to go and may become more acceptable long term. Recent fast charging battery developments for instance are an example of limiting battery size which brings some benefits, but more is needed. Hydrogen technology and carbon capture are not quite there in my opinion and the whole blue hydrogen issue is questionable. I think we will probably need both in the medium term. Carbon offsets were a good way of raising awareness and may have marginal effects on carbon sequestration, but are largely fraudulent IMO and not particularly helpful at this stage of the climate crisis.
Thanks for the ITM suggestion. I am interested in investing in alternative power companies in the medium tern, but would like a little more progress with CASP before shifting in that direction.
The tax breaks are there as recompense for not building houses. Think of it as a carbon offset for holding CASP shares. My idea on that was to use the profits from CASP to buy an electric car and install solar power on the roof, but it hasn't quite worked out like that yet!
I downsized from a third of an acre (with a small bit of woodland at the end) 10 years ago and now have a small manageable urban back garden. Things you need as you get older: easy access to shops, doctors, hospitals, restaurants, cinemas, theatres, bus stops, railway stations and countryside.
Basically what has happened this afternoon is that the MMs have activated the safety over-ride cliutch on the ratchet ready for it to morph into a spinning top and lurch off in an unexpected direction next week.
I swapped teaching/ management for renovating a wreck of a house and getting involved with local authority partnership boards. Slowing down a bit now!
We're 7th on the share risers list this morning, although that's a bit misleading as it's based on the closing price of 3.24p. For some reason they used a single sale price late in the day which was below the closing spread. Strange!
There are some traders who watch the risers looking for a quick buck. Being in the top ten twice this week can do us no harm although may increase volatility.
While we have been excited by CASP climbing to 10th position on the risers board for no apparent reason, Brent has quietly sailed through the $70 mark, briefly touching $71 before settling back a little.
