Oil companies employed marine geologists and palaeoclimatologists in order to search effectively for oil and gas. They were generally in separate research sections, and being academics were at the leading edge of climate research. So it's not surprising that they were in line with other climate scientists at the time, with who they interacted. Of course the people that actually ran the oil companies weren't interested in any of that. They just wanted to know where the oil was. Which is why they should be forced to pay us back now for the damage they have done to the environment (what those people who ran the oil companies called "external costs"). |

Painfully slow process as other* bids need to be considered and the news is a bit behind but
Rolls-Royce seeks to progress mini nuclear plants by site visits
www.reuters.com/business/energy/rolls-royce-seeks-progress-mini-nuclear-plants-by-site-visits-2023-01-13/Recent share price rise is mostly due to their 'old' business, improved global optimism for air travel (in part due to lower energy prices) and appointment of a new CEO. So a 'hold' IMO although if you bought some below 70p then worth putting a bit of that cash in the bank IMO  * I wouldn't be surprised to see either a takeover bid or some form of collaboration but RR could (and IMO should) be awarded the first contract for a SMR very soon (but I have been saying that for a while and these things always take longer than hoped). |

“South Korea’s HD Hyundai is looking at building nuclear-powered cargo vessels as the industry seeks to end its dependence on polluting heavy fuel oil.
“We're thinking of putting nuclear into a ship for a zero carbon shipping future,” chief executive Ki-sun Chung says.
HD Hyundai is considering the shift to nuclear ahead of green regulations that will apply to global shipping from 2025. It is not alone.
“At the present time there are a number of organisations looking at nuclear in the marine space for both shipping and offshore applications,” says Mark Tipping of Lloyd's Register’s, an industry body that helps set safety standards in the shipbuilding industry.“
…
However, the pace of change is picking up. Shipping lines such as AP Moller-Maersk and CMA CGM are already placing contracts with Hyundai for vessels powered by alternative fuels, Chung tells The Telegraph.
…
A shift to nuclear-powered civilian shipping could reap dividends for Britain. Rolls-Royce has supplied the Navy with reactors for its submarines ever since the 1960s, and the Derby-based company is working on small modular reactor designs intended for civilian electricity generation.
…
For now, it is looking to launch alternative, non-nuclear fuels. Chung of HD Hyundai says his company is working on ships that could be powered by liquefied natural gas (LNG), methanol, ethane and even ammonia.
“We are also trying to bring in a hydrogen burning engine around 2025-2026,” continues Chung. “And beyond that we are also trying to introduce fuel cells into marine propulsion.””

Microsoft are trialling using hydrogen as backup power for their data centres, replacing diesel generators “ Microsoft turned to PEM fuel cells as a potential solution to the backup diesel generator challenge in 2018. PEM fuel cells are commonly used in the automotive industry because, like diesel engines, they are quick to turn on and off, and can follow a load up and down. That fast reaction and load following capability is well suited for backup power at datacenters, Monroe noted.
“We started looking at the projections of the costs and the availability of hydrogen and we started to really believe that this might be a solution. And, so, we built a vision. It took us from a rack to a row to a room to a datacenter,” he said.
In 2018, Microsoft collaborated with engineers at the National Renewable Energy Laboratory in Golden, Colorado, to power a rack of computers with a 65-kilowatt PEM fuel cell generator. Then, in 2020, the team hired Power Innovations in Salt Lake City, Utah, to build and test a system that could power 10 racks – a row – of datacenter servers for 48 consecutive hours with a 250-kilowatt hydrogen fuel cell system.
After that successful proof-of-concept demonstration, the team set out to prove the viability of a three-megawatt system, which is of sufficient size to replace a diesel generator at a datacenter.
…
James envisions a future where datacenters are outfitted with hydrogen fuel cells, hydrogen storage tanks and electrolyzers to convert water molecules into hydrogen with excess renewable energy. During periods of high energy demand or when the sun stops shining and the wind stops blowing, Microsoft can ramp up the fuel cells, taking the datacenter load off the grid, freeing up grid power for others to use.”news.microsoft.com/source/features/sustainability/hydrogen-fuel-cells-could-provide-emission-free-backup-power-at-datacenters-microsoft-says/ |

Microsoft are trialling using hydrogen as backup power for their data centres, replacing diesel generators ... Tesla is only the business is it today due to massive tax credits and Biden is 'bunging' hydrogen, creating not only supply but also demand from the 'wait and see' (what's in it for me) crowd:
Biden’s Inflation Reduction Act makes green hydrogen profitable at scale, Goldman Sachs says
www.cnbc.com/2022/11/30/the-ira-makes-green-hydrogen-profitable-at-scale-goldman-says.htmlNB As pointed out in previous comments then the recent, huge recent drop in nat.gas prices does pose a risk of a return to 'dither and delay' but great to see 'boost it like Biden' trickling down to the demand side. |

davem - minewater geothermal has huge potential. In terms of the available energy, it was recently assessed by a Durham University study as offering up to 25% of total UK heat demand, which is pretty staggering, for a 'free' naturally replenishing heat source, and the location of the exhausted coal beds coincides nicely with plenty of demand. However, the problem is the economics. I've worked on a number of these schemes and the capital costs are substantial, for a start, but there is also the issue of the power required for the extraction, circulation and and heat pumps. I haven't revisited the numbers recently, but current power prices would likely make any such schemes uneconomic, even if the capital costs were covered, but if we're serious about net zero, it's not beyond the wit of man to create fixed electricity tariffs for such systems to ensure viability.

"The UK is wasting a lot of wind power" blog posting by Archy de Berker archy.deberker.com/the-uk-is-wasting-a-lot-of-wind-power/A useful discussion on why the lack of grid capacity between Scotland and England means we cannot make full use of wind power generation and why it will get worse in future. |

A useful discussion on why the lack of grid capacity between Scotland and England means we cannot make full use of wind power generation and why it will get worse in future. A pretty good and fairly concise article - well worth a read. But I think your conclusion above is a bit pessimistic? It *needn't* get worse in future, it's largely dependent on a grid upgrade and the other points mentioned in the article. |

leftieliberal - yes, that's a good post. We've been in discussion with National Grid about the E2DC link and their plans to add connection capacity at the southern end. The area around Hawthorn Pit is heavily constrained, but still offers good opportunities for generation if the grid issues are sorted, but the E2DC infrastructure won't come online until at least 2028. It was first mooted around ten years ago, and it's just gross incompetence that this hasn't been conceived, planned and built by now.

Not really, national grid has no particular interest in guaranteeing Uk energy supplies. It wants to maximise its profits, which might very well mean energy shortages! Apart from that, obviously, government has placed obstacles in the construction of new infrastructure instead of expediting it. |

A pretty good and fairly concise article - well worth a read. But I think your conclusion above is a bit pessimistic? It *needn't* get worse in future, it's largely dependent on a grid upgrade and the other points mentioned in the article. See section 1 of the report cited in the blog post www.drax.com/wp-content/uploads/2022/06/Drax-LCP-Renewable-curtailment-report-1.pdf and particularly the paragraph at the top of page 9: Hence, we would not expect this reduction to continue in future. Offshore wind capacity in GB is set to scale up drastically from 10GW in 2020 to meet the new government target of 50GW by 2030. The Scottish government is targeting 11GW by 2030 (increasing from 1GW of existing capacity in 2020)[6], and the ScotWind auction in January 2022[7] exceeded expectations by awarding option agreements to 25GW of Scottish offshore wind projects. The transmission infrastructure investment is expected to lag behind this wind capacity deployment, and there is likely to be a corresponding increase in wind curtailment. National Grid ESO’s modelling shows a significant increase in network constraint costs through to the end of the decade[8], and this analysis was produced prior to the government’s new ambitions being announced, which are likely to increase costs further.

Related to above then more "yes, and" solutions include increased capacity on existing transmission cables: National Grid trials new technology which allows more renewable power to flow through existing power lineswww.nationalgrid.com/national-grid-trials-new-technology-which-allows-more-renewable-power-flow-through-existing-powerFull use of the 'day' (and other time periods) that has relevance to location of 'storage' (can't quickly find a link for people to read but should be obvious that 'shifting' can be far more efficient that it currently is) Future international interconnectors (notably Norway to England, the collective are less keen on significant increase in other interconnections other but appreciate a few more would be useful). Again should be obvious. Possibly the only thing that hasn't been discussed before is what would happen if Scottish electricity became a lot cheaper (on a relative basis). Sounds great until you consider issues such as Scottish wind farms would then become less economically viable (on a relative and quite likely absolute basis), Indy, etc. Although if you have Real World interests in electricity generation in S/E England then 'fine by my' NB Above are all "yes, and" additions that each help a bit towards a 'known, known' problem and have mostly been discussed before, so back to Real World and new stuff pour moi. PS and another link I might have posted before. Still in 'beta' test but for anyone who thinks they know better, they can play around with what they would do: www.nationalgrideso.com/future-energy/the-pathway-2030-holistic-network-design/interactive-map |

Key is to enable power to get from where generated to where most consumed? |

Key is to enable power to get from where generated to where most consumed??? One outcome of a crude locational pricing approach would be the opposite: stop making so much electricity where it is not consumed + start making more electricity where it is consumed = less need for interconnectors (including additional Scotland-England capacity) NB I'm simply highlighting that of all the "yes, and" options then 'locational pricing' is a tricky one - although if combined with other significant changes to electricity pricing (that I don't have time to go into at the moment) then one that I wouldn't oppose. |
