Everything said about Rondo Energy, oldest first

Apr 9, 2024 bullish
Prediction Not checkable as stated
O'Donnell: Path is clear to decarbonize industrial heat within 15 years
“We see the path clear with what we're doing to decarbonize most of that within about 15 years, given the constraints on how fast wind and solar can be built, and there aren't meaningful production constraints on the brick materials that we use.”
John O'Donnell Apr 9, 2024 ▶ 27:07 The rise of heat batteries
Apr 9, 2024 bullish
Prediction Open · timeframe Dec 2030
O'Donnell: Intermittent renewable power will economically eclipse fossil fuels globally by 2030
“By 20 30 in most of the industrialized world, the conditions that exist in the six European countries where we're developing projects now in Australia and the half dozen US states, those market conditions exist in most of the industrialized world that you can …”
John O'Donnell Apr 9, 2024 ▶ 27:46 The rise of heat batteries
Apr 9, 2024 bullish
Assertion Supported
O'Donnell: Rondo heat batteries address 90% of global industrial heat
“The temperatures that today's Rondo heat batteries deliver serve about 90% of all the industrial heat used in the world.”
John O'Donnell Apr 9, 2024 ▶ 26:03 The rise of heat batteries
Apr 9, 2024 bullish
Assertion Supported
O'Donnell: 1,000°C bricks match lithium-ion energy density at one-tenth the cost
“And when you heat a brick to a thousand C, it stores as much energy per pound as a lithium ion battery. Costs 10 times less, lasts 10 times longer.”
John O'Donnell Apr 9, 2024 ▶ 9:11 The rise of heat batteries
Apr 9, 2024 bullish
Assertion Not checkable as stated
O'Donnell: Rondo heat batteries cost $5/kW marginally at 98% efficiency
“A round of heat battery is not a 2000 dollar or 1000 dollar a kilowatt electrolyzer that delivers heat at 50% efficiency. It's about five dollars a kilowatt on a marginal basis for these electrical wire heaters, and it's 98% efficient at turning electricity in…”
John O'Donnell Apr 9, 2024 ▶ 14:59 The rise of heat batteries
Dec 11, 2024 positive
Assertion Not checkable as stated
O'Donnell: Rondo has caused zero significant outages at Calgren
“Rondo has not caused five minutes of outage for Calgary since we started working there.”
John O'Donnell Dec 11, 2024 ▶ 10:08 A complex path for building heat batteries
Dec 11, 2024 positive
Disclosure
O'Donnell: Rondo is partnering with European utilities on heat-as-a-service
“Now, we have utilities that we're working with at scale in Europe who are combining these things to offer heat as a service to a customer.”
John O'Donnell Dec 11, 2024 ▶ 11:37 A complex path for building heat batteries
Dec 11, 2024 neutral
Disclosure
O'Donnell: Rondo Financed Initial Commercial Pilot on Balance Sheet
“Because this one was the size that it was. We financed this on balance sheet.”
John O'Donnell Dec 11, 2024 ▶ 13:19 A complex path for building heat batteries
Dec 11, 2024 bullish
Assertion Supported
O'Donnell: Rondo Brick Storage Holds More Energy Per Kilogram Than Lithium-Ion
“We store a little bit more energy per kilogram than a typical lithium-ion battery pack in brick”
John O'Donnell Dec 11, 2024 ▶ 15:32 A complex path for building heat batteries
Dec 11, 2024
Disclosure
O'Donnell: Rondo Energy Acts as Prime EPC on Early Projects
“In these early projects, we are prime. We are the prime EPC.”
John O'Donnell Dec 11, 2024 ▶ 20:05 A complex path for building heat batteries
Dec 11, 2024 bullish
Prediction Open · timeframe Dec 2027
O'Donnell: Full Calgren installation will be about 600 MWh
“Step one, this was a pilot for the full-size installation will be about 600 megawatt hours”
John O'Donnell Dec 11, 2024 ▶ 8:38 A complex path for building heat batteries
Dec 11, 2024 positive
Assertion Not checkable as stated
O'Donnell: Rondo uses identical core materials when scaling to 100+ MWh systems
“There are no changes in the materials. The materials that we used in making these first things are the materials that we're using in all the current things.”
John O'Donnell Dec 11, 2024 ▶ 27:28 A complex path for building heat batteries
Dec 11, 2024 neutral
Disclosure
O'Donnell: Rondo Sold Calgren Heat at a Discount to Gas Prices
“Here, just for simplicity, because it was on balance sheet, we said, fine, we will sell you heat at a discount to whatever the then gas price is.”
John O'Donnell Dec 11, 2024 ▶ 14:58 A complex path for building heat batteries
Dec 11, 2024 neutral
Insight
O'Donnell: Fifty-Kilogram Bricks Are Suboptimal for Grid-Scale Thermal Storage Construction
“A 50 kilogram brick is almost perfectly the wrong size. It takes two people to handle it, and there are a lot of them. So to the extent that we could make larger single bricks, we could reduce crane operations or people hours building these things.”
