My terrain satisfies all the requirements but one, everyone wants to be in 1km range from the electric station
Why?
Just a quick brainstorm, or maybe it's a brain fart, on this topic. I was looking at the formula for determining the potential energy for a floating ocean weight drop system
Mwh storage =
(wt kg)(.6 factor for Archimedean of water)*(9.81)*(Meter depth)
3 600 000 000joules
Pilots on these types of systems have only accompanied offshore wind for the most part. Was thinking Cali coast u can get to 3000m depth pretty quickly ,30-40 miles out at some points. Some salvaged high displacement hulls for a few hundred thousand tons, dredged sand filled weights, tethering/mooring, submarine hvdc cable, high eff motors/gens... Seems like you could get to a very economical gwh/$, albeit not at the efficiency of battery storage? gravity and pumped hydro are in the 80%eff neighborhood i believe. I think you would lose some efficiency here with water friction and inverter/transmission losses. Any thoughts on why this wouldnt be a viable storage method serving connections on land as opposed to wind farms?
I felt like gravitricitys 3.3gwh in China at a $1bil+ was more of a fail than win since the cost is comparable to battery systems.
Paladin Energy (MCAP: $3.6B) is acquiring Fission Uranium for $1.1B, or $1.30/share, reflecting a 30% premium over FCU’s last closing price. This acquisition is consistent with our earlier prediction that majors would pursue M&A to secure long-term supply. Given that Russia contributes to 35% of global enriched uranium production, we believe the uranium supply chain remains highly vulnerable.
FCU is advancing a high-grade uranium project in the Athabasca Basin, hosting 130 Mlbs in resources. A recent feasibility study revealed an AT-NPV8% of $1.6B, using US$75/lbs uranium. PDN is paying 60% of the AT-NPV8%, or $7.4/lb, in line with the sector average.
I’m a new homeowner and looking into switching energy suppliers
I’d like some advice on how to best pick a new fixed tariff
The first problem I’ve run into is that I can’t find the MRPN number for gas on my rebel energy bill
I used meerkats to find a cheaper tariff so I might switch to eon but I’d like a few more options and I need the mrpn to get a direct quote to switch anyway
Economics and the weather were the main drivers influencing the production of energy in Canada during the first quarter of 2024. Here are a few highlights:
***
Au cours du premier trimestre de 2024, la production d’énergie au Canada a été principalement influencée par la conjoncture économique et les conditions météorologiques. Voici quelques faits saillants :
Is there any smart, creative, cost-effective and practical idea, to turn atmospheric heat into electric energy ?
Coming from a hot country, where average summer temperatures can reach 40c in some regions, i was very curious, is there a way to kill two birds with one stone.
Polysilicon:
The mainstream concluded price for mono recharge polysilicon is RMB 34/KG, while mono dense polysilicon is priced at RMB 32/KG and N-type polysilicon is currently priced at RMB 38/KG.
This week, producers are mainly fulfilling previous orders, while downstream ingot manufacturers continue to purchase based on demand. In the short term, ingot manufacturers' operation rates remain low, leading to sluggish polysilicon orders. Regarding production plans, some small producers are gradually resuming operations, and others are undergoing maintenance. However, new capacity from leading producers is still coming online, increasing overall production. Polysilicon inventory has slightly increased this week, primarily due to the continuous addition of new capacity. Currently, the price of industrial silicon is declining, slightly boosting the profits of polysilicon companies. However, they still face inventory build-up due to a supply and demand mismatch. As a result, polysilicon prices are expected to remain low.
Wafer:
The mainstream concluded price for M10 P-type wafer is RMB 1.20/Pc, while G12 P-type wafer is priced at RMB 1.75/Pc. The mainstream concluded price for M10 N-type wafer is RMB 1.10/Pc and G12 N-type is RMB 1.65/Pc. The mainstream concluded price for N-type G12R wafers is RMB 1.45/Pc.
Operation rates in the wafer sector remain low, but inventory consumption by wafer producers is effective, leading to a weekly decline in wafer inventory. However, demand for cells from the module sector is decreasing. The large capacity remains a concern, and if the utilization rates in the wafer sector rebound, cell inventory is expected to increase.
Regarding price trends, wafer inventory has gradually decreased, and some manufacturers have even raised their prices, though this has not been well-received by customers. The prices in both upstream and downstream sectors are below cost, making it challenging for wafer producers to increase prices. However, leading manufacturers are adopting pricing strategies to push smaller producers to clear out their capacity. In conclusion, the wafer sector may be the first to recover, but this recovery is limited, helping producers avoid losses rather than generating profits.
Cell:
The mainstream concluded price for M10 cell is RMB 0.300/W, while G12 cell is priced at RMB 0.320/W. The price of M10 mono TOPCon cell is RMB 0.30/W, while that of G12 mono TOPCon cell is RMB 0.35/W.
Affected by the module sector, orders for cell producers are slightly sluggish, impacting production plans in the cell sector. The benefits of TOPCon cell technologies have rapidly declined due to surplus capacity and weakening downstream demand. Additionally, aside from leading producers, others face immediate losses upon commencing production. This week, cell inventory is expected to continue rising. Regarding prices, as demand for modules declines, competition for orders among enterprises intensifies, putting future prices under continued pressure.
Module:
The mainstream concluded price for 182mm facial mono PERC module is RMB 0.80/W, 210mm facial mono PERC module is priced at RMB 0.82/W, 182mm bifacial glass PERC module at RMB 0.82/W, and 210mm bifacial glass PERC module at RMB 0.84/W. The mainstream concluded price for 182mm bifacial TOPCon modules is RMB 0.86/W, and 210mm bifacial HJT modules at RMB 1.00/W.
In the module sector, orders are sluggish, leading to reduced production plans and increased inventory. Overseas demand is expected to be limited as key regions enter the offseason. Additionally, the export volume from Southeast Asia to the USA is declining, which is difficult to compensate for. Domestically, the halting of policies related to residential PV projects in some provinces is negatively impacting residential solar installations, causing fluctuations in distributed PV capacity installations. Ground-based power plants are steadily progressing, but at a slow pace.
Some tier-2 and tier-3 manufacturers are lowering prices to secure more orders, while leading manufacturers have some flexibility in pricing. As a result, actual module prices may decline.
