My highlight in June was the week spent in Cape Town with Amanda and Jon for Physical Separation '24 and Mill Circuits '24, both very enjoyable conferences, made even more enjoyable by the very unseasonable winter weather in Cape Town.

Our decision to hold these conferences in Cape Town, rather than in Falmouth, was vindicated by the awful train journey I experienced returning to Cornwall from London, where due to the usual industrial action the train was packed, with people standing in the aisles. So it will be good to be back at the Vineyard Hotel again in November for Process Mineralogy '24 and Critical Minerals '24 and to enjoy the amazing views each morning from the hotel bedroom window.
Luckily, when my flight was approaching Cape Town International it flew over Claremont and Newlands, with the same view of the mountain, but from a different perspective, looking over to the city centre. What a location for a conference!
Following the conferences Jon and I returned home to Luxembourg and Falmouth respectively, while Amanda took the short flight to Namibia for the SAIMM's Rare Earths conference, making the most of the pre-conference time to explore Namibia's amazing dunes. Her report on the conference will be published soon.
The following week Amanda was in Luxembourg, visiting Jon and family.

The Cape Town conferences unfortunately clashed with the UK Mining Conference in Cornwall, which was held, as last year, in Falmouth. By all accounts it was another great event, attended by 370 delegates, with 30 exhibitors. Although I was unable to report on the conference, Carly Leonidas, the European Editor of Engineering & Mining Journal has provided an excellent report, highlighting how key UK battery metal projects are edging closer to production.

In June the race was on for the next Government, which will be decided on Thursday. Labour leader Sir Keir Starmer's proposals for a publicly-owned company called Great British Energy to invest in clean and renewable energy are a central plank of Labour’s plans to entirely remove fossil fuels from UK electricity production by 2030, five years earlier than current government plans. But some energy analysts don’t think electricity decarbonisation as soon as 2030 is practically achievable as it would require the total installed UK offshore wind generating capacity to more than triple over the next six years. Solar electricity generation and onshore wind generating capacity would need to roughly double to replace the electricity currently provided by gas-fired power stations.
According to the experts, and reported by the BBC, one of the biggest obstacles in terms of hitting the 2030 target is not the cost of installing new solar panels and wind turbines, but the practical difficulty, due to planning regulations and local opposition, of upgrading the UK’s electricity grid network. No mention here, however, of the obvious fact that when the wind doesn't blow or the sun doesn't shine, gas is going to be needed, along with the steady supply of nuclear energy, to keep the lights on (posting of 11 December 2023). Unless, of course, when the wind blows strongly, and the sun shines brightly, the intention is to store excess energy in mega-batteries or produce an attractive energy source, green hydrogen?
And as usual, there is not a single mention of where the critical minerals, necessary for renewables, will come from, or of the huge amount of energy needed to mine and process them. As noted in the posting of 27 May renewable energy technologies, clean water, wastewater, electricity cannot exist without the most critical of metals, copper, which is likely to be the key commodity in the next few decades. Solar and wind farms, often spread out over large areas, require more copper per unit of power produced than do centralised coal and gas-fired power stations. Electric vehicles use more than twice as much copper as petrol cars do.
Although more copper is being recycled, it won’t be enough to cover demand, so the only alternative is to mine more and to develop secondary processing routes, as much copper and other critical metals are tied up in the tailings dumps of many years ago. It would be good to see some of the energy experts and politicians at Critical Minerals '24 in November!!

It is reported that to draw down, for example, the Scotwind licenses for build floating renewables to yield 30GW we need to be building one device every day between now and 2045. So far none have been built nor is there the transmission capacity to distribute the power nor has the investment for floating wind turbine or for harbour services been secured. So speaking for offshore wind, I would say its not feasible. The environmental surveys (which every one of 24 farm sites has to do for multiple factors) are yet to be agreed and executed . I believe with more time and commitment it is possible well beyond 2030.

My first comment, Barry. How sad that the current state of UK railways was a factor in holding an International conference somewhere else in the world!
ReplyDeleteI'll follow up with something about "net zero" later.

Hi Sam
DeleteThe increasing unreliability of the trains services wasn't the only reason for moving the conferences to Cape Town. There were other factors such as cost and delays in issuing visas, unreliable courier services delivering essential conference materials from our suppliers, and others. It's a shame we had to move the conferences, as Falmouth is a great location and we could not fault our new venue, the National Maritime Museum. So for the time being, until Britain mends itself, we will be at the excellent Vineyard Hotel.
