And down under, milestones continue to fall in Australia’s rapidly evolving electricity grid, with rooftop solar meeting all of South Australia’s native or underlying demand in the early afternoon on Saturday.

For now, it keeps two gas units running at low capacity to maintain grid security, but that need will be redundant once the new link to NSW is completed in a few years time.

You may have caught wind about head winds in the U.S. offshore wind development arena this week.

Anyways, a VP at Ørsted wrote this:

"Offshore wind is said to be in the middle of a perfect storm for exactly the reasons that all hit our US projects: supply chain delays, increasing interest rates and tax regimes that continue to support fossil fuel and are at best neutral to, but often detrimental to, the development, construction and operation of renewable energy."

In the models with only short-duration lithium-ion batteries available, over 60 GW of battery capacity is built by 2040 to shift renewable generation and meet peak demand. However, this capacity only provides 538 GWh of energy storage.

Whereas when long-duration and multi-day storage are available, total storage capacity needs drop to around 40 GW. But critically, total energy storage capacity grows nearly 10x to over 5,000 GWh.

Stellantis N.V. and Controlled Thermal Resources Holdings, Inc. (CTR) has announced a major investment of over $100 million from Stellantis to advance the development of CTR’s Hell’s Kitchen project, the world’s largest geothermal lithium project with a total resource capacity to produce up to 300,000 metric tons of lithium carbonate equivalent each year.

The 35-MW geothermal power plant of Sosian Energy in the Menengai geothermal field in Kenya has started supplying electricity to the national grid. Menengai hopes to develop a combined capacity of 105 MW.

Electricity from it is being sold at a rate 6.9 US cents per kWh. This is a competitive price and is expected to help displace expensive power generating capacity mostly from thermal plants.

The German government is looking at further developing deep geothermal energy to create a nationwide climate-neutral heat supply by 2045. According to studies, deep geothermal energy could generate around 300 terawatt hours of heat annually from an installed capacity of 70 GW -- more than half the future heat demand of all buildings.

Geothermal and ground coupled heat pumps use in the U.S.is growing too.

Newsmast is new to Mastodon and #mastodonenergy. We’re a knowledge-based platform pooling facts, data and ideas. Built on Mastodon’s open-source technology, bringing together academics, journalists, charity workers and people who know their stuff from across the fediverse.

Newsmast is made up of curated communities of interest, where we seek out and follow experts to lead the conversation; together with diverse voices, marginalized communities and people on the ground.

I like how Sankey diagrams can highlight how much wasted energy there is but this one that Mark Z. Jackson lumps in with .

Isn't that a mistake since the nuclear is the heat-based system of producing electricity so therefore accounts for almost all of that wasted energy (pollution)?

After posting this I thought I should add the tag as well as wondering about adding a third level of info that adds the energy used to create the energy generators too?

I so wish that would migrate to because of the discussion going on around Sammy Roth's nice new article in the @latimes on rooftop solar in relation to solar farms.

Anyways, my 2 cents is that building out our distribution grid requires the political will to combat entrenched and powerful forces along with a lot of NIMBYism which is impacting the solar farm industry significantly too. So, I like reducing demand on the grid by adding and at POU.

Back onto the subject of the new disruptive arbitrage industry in

Battery storage capacity for
California ISO is now over 5GW.

Report for end of May showed 4,885 MW of installed storage.
caiso.com/Documents/Key-Statis

Another 548 MW came online in June - so total is now 5,433 MW.

And since the capacity is near 4 hours, that's potentially 21 GWHs of clean electricity being time shifted - often twice a day. h/t @CommercialSolarGuy

Welcome to the Fediverse from that foul site. We don't have an algorithm determining what we see so we have to create our timelines ourselves by following plenty of other posters.

If you understand this reference you might consider following this account for example, ELoon runs his network as bad as does or at least check the hashtag occasionally.
