Researchers just cracked a major clean energy challenge: producing hydrogen at scale without using precious land or freshwater.
The University of Exeter team simulated a floating solar system in Oman that desalinates seawater and generates 1,755 kg of hydrogen daily at $9.5/kg. It's a game-changer for hot-climate regions.

Off-grid floating PV-desalination system for hydrogen production
Scientists have simulated a solar-powered hydrogen production system comprising 32,050 photovoltaic panels, a pumping system, a seawater reverse-osmosis desalination unit, an electrolyzer, and a hydrogen storage tank. Operation of the system in Oman could potentially yield a levelized cost of electricity of $0.05/kWh and a levelized cost of hydrogen of $9.5/kg.

@… Yes, I'm off grid, love my solar. Opposed to the AI trained on internet slop by amoral companies, not the concept.

I've got solar panels 5kWh battery installed!
The battery makes the largest impact. I can charge during low-CO2 off-peak time and avoid the grid during the peak hours.
The #solar output I get is underwhelming (bad roof orientation), but the battery is going to pay for the system. I could have gotten just the battery!

Letting EVs take a load off the grid could result in 'negative emissions' while saving drivers money
Letting electric vehicles strategically charge from and discharge to the grid could spark environmental and public health benefits for Americans, according to a new study from the University of Michigan and Carnegie Mellon University. The findings are published in the journal Environmental Science & Technology.

Rise in Chinese off-grid coal plants in Indonesia belies pledge to end fossil fuel support
A surge in the supply of Chinese-backed coal-fired power plants built to supply electricity to Indonesia’s fast-growing nickel mining and processing sector is undermining Beijing’s efforts to dial back support for fossil fuels, a study released Nov. 3 has found. In his speech to the U.N. General Assembly four years ago, China’s president, Xi Jinping, […]

MeshCore is opensource

On-Grid Equivalence of Continuous-Time Doubly Selective Channels: A Revisit of Bello's Models
Significant studies on communications over doubly selective channels have utilized on-grid DD channel models, which are previously investigated in Bello's seminar paper in 1963. The DD grid is typically specified by the bandwidth and time duration of the transmission frames. However, the physical channels are determined by the propagation environments and they are typically off-grid. Hence, there is often a gap between an actual physical channel and the on-grid model. This paper revisits the on…

Sharing the benefits of grid-scale batteries and solar/wind by trading in western US. The current 15 minute market in California Now going to day ahead market.
(I think made possible with recent massive grid-scale batteries allows evening out of renewables)
California now runs 5pm-8pm electricity use on batteries. Turn off more plants cuz can plan for a full day.
Thoughtful article on wholesale electricity grid coordination markets. Sounds dry, but cool:

Yes, Switzerland🇨🇭 loves ⛰️ peaks. But when it comes to solar power, it's okay to take a little bit off the top.
From 2026 onwards, (new) solar power installations must limit their peak capacity to 70%. This only slightly reduces production, but it does reduce the simultaneous load on the grid.

Neue Regeln bei der Einspeisung von Solarstrom
Die Energiewende ist in vollem Gang. Solaranlagen boomen und liefern immer mehr erneuerbaren Strom. Eine positive Entwicklung, die auf unsere Energie- und Klimaziele einzahlt. Doch wenn an sonnigen Mittagen alle Solaranlagen gleichzeitig Strom einspeisen, entstehen Leistungsspitzen, die das Stromnetz an seine Grenzen bringen. Es herrscht sozusagen Stau im Netz.

Aggregate Modeling of Air-Conditioner Loads Under Packet-based Control with Both On and Off Grid Access Requests

Aggregate Modeling of Air-Conditioner Loads Under Packet-based Control with Both On and Off Grid Access Requests
Coordination of distributed energy resources (DERs) can engender flexibility necessary to improve grid reliability. Packetized Energy Management (PEM) is a method for coordinating DERs, such as thermostatically controlled loads (TCLs) and electric vehicles, within customer quality-of-service (QoS) limits. In PEM, a DER uses local information to offer flexibility by sending a request to the DER coordinator to turn-ON or turn-OFF. Much work has focused on modeling and analyzing aggregations of DE…
