| The Visual Capitalist: "A Visual Crash Course on Geothermal Energy" |
This session of the radio show shares my conversation with Ted McIntyre, Franklin resident and climate activist. We recorded this via the Zoom conference bridge Tuesday, October 25, 2022.
In this episode our conversation covered the following topics:
Microgrids
South Carolina residential building auto based
DPU and municipal aggregation approval cycle
Building code, stretch code revisions pending
Offshore cable system
Mother Jones says ‘microgrids’ are good
This discussion continues our journey understanding the MA roadmap toward net zero and while it helps me “make sense of climate”, we hope it helps with your understanding as well.
If you have climate questions or Franklin specific climate questions, send them in and we’ll try to answer them in a future session.
The conversation runs about 40 minutes. Let’s listen to my conversation with Ted

microgrid - Merriam Webster added the word in September

teaser to come back to microgrids
South Carolina massive residential building underway in 'low country' outside of charleston.
no mass transit, while 55 housing is being built, all are hostage to the automobiles
not sustainable for net zero, or for those 55+ who as they age are going to be standed out there
municipal aggregation, we have it, others can't get it
public ownership of utilities I don't think it the answer, we need to ensure appropriate board and oversight of the utilities doesn't create/continue the fossil fuel domination

Hard to find a good contractor.--- this will be important as we go forward in MA>
offshore cable system, rather than extending electric grid above ground

| Eversource/Framingham pilot construction update |
"Often described as a giant tower of Jenga blocks, Boston University’s Center for Computing and Data Sciences shows no outward signs of leading the race to sustainable energy design. No rooftop wind turbines grace its heights; no solar panels are mounted on the multiple roof decks jutting out from the building’s core.What makes this building unique lies deep underground, where water circulating through 31 geothermal boreholes will supply 90 percent of its heating and cooling needs when the building opens, as scheduled for later this year. Through a process called geothermal heat exchange, water pumped from 1,500 feet underground will draw upon the near-constant temperature that prevails beneath the earth’s surface – 50 to 60 degrees Fahrenheit year-round.
Even on the coldest New England days, water prewarmed by the earth will be circulated through heat pumps that will further raise its temperature to deliver heat where needed. On warmer days or in heavily occupied spaces where heat builds up even in winter, the heat exchangers will draw on the earth’s cooler temperature to provide air conditioning."

| Making Sense of Climate with Ted McIntyre #12 |
Via National Grid US:
"In Massachusetts, we have submitted our Geothermal Program Implementation Plan to the Department of Public Utilities for approval. Anyone wishing to comment on our plan may submit written comments to the DPU by 5:00 p.m. on Friday, July 29th, 2022. ngrid.com/3Hz1hsf "
You can find the National Grid plan referenced -> https://www.nationalgrid.com/document/146251/download
From their plan:
"National Grid’s vision for fossil-free heat targets a hybrid approach. Just as we have decarbonized electricity with wind and solar, we can decarbonize the gas system with renewable natural gas and green hydrogen."
 |
| Comments open for National Grid's Geothermal Program Implementation Plan until July 29, 2022 |
"Miles below ground, where pressures are intense and temperatures far exceed the boiling point of water, dense layers of super-hot rocks offer the promise of a natural, inexhaustible supply of clean energy.
Environmentalists have long dreamed of a way to reach those depths to tap the potential geothermal energy in those rocks, but the technological and financial barriers have been too great.
Now, officials at an MIT spinoff say they believe they’ve figured out how to drill as deep as 12 miles into the Earth’s crust, using a special laser that they say is powerful enough to blast through granite and basalt. "

FM #709 = This is the Franklin Matters radio show, number 709 in the series.
This session of the radio show shares my conversation with Franklin resident and climate activist Ted McIntyre. We recorded this via the Zoom conference bridge Jan 20, 2022.
We cover the following topics within the realm of climate change
As we did not get to cover all the points of the legislation, stay tuned we’ll schedule at least another session.
The recording runs about 38 minutes, so let’s listen to my conversation with Ted McIntyre. Audio link -> https://franklin-ma-matters.captivate.fm/episode/fm-709-ted-mcintyre-making-sense-of-climate-change-01-20-22

"Untapped potential: There's enough heat inside the earth to meet total global energy demand twice over. But harnessing it requires drilling deep underground and transforming that heat into a usable form of energy. That's difficult and expensive, which is why geothermal power only makes up only about 0.3% of electricity generation worldwide, despite the fact it's more consistent than virtually every other form of renewable energy. However, it's now getting a boost, thanks to a $84 million Department of Energy project to build four demonstration plants. They'll test enhanced geothermal systems, an experimental form of the technology.
Exhausted supplies: The most accessible geothermal resources in the US have been tapped, and it's hard to figure out how many more potential sites may be out there, and where they might be. Some researchers and startups are trying to expand into new places by pumping fluid into impermeable rock to force cracks open. This creates space where water is free to move around and heat up, producing the steam needed for power.
Barriers: Despite geothermal's vast potential, reaching these resources won't be easy. The process has been shown to trigger earthquakes, and despite the injection of government cash, financing geothermal projects can also be a challenge. "

| What it will take to unleash the potential of geothermal power |
"A half-hour’s drive from Iceland’s capital city, Reykjavik, one happens upon a scene straight out of a science fiction movie: Plumes of white steam billow above the Hellisheiði volcanic region. The air is suffused with the unmistakable stench of sulfur — several thermal springs, their mineral-rich waters a favorite of local bathers, are nearby. The rays of a waning sun are no match for the thick cloud cover that hangs over the rough terrain on a crisp early autumn day.It is here that the future and the present collide in a structure about two stories high. This is the Orca Plant, the world’s largest facility for capturing carbon dioxide directly from the air and storing it deep underground. The steam we see is being released into the sky from geothermal drilling sites. The captured CO2 is mixed with water and injected into those holes in the ground.The Orca Plant, built, owned, and operated by the Swiss company Climeworks, kicked into whirring, carbon-sucking life last month, fueled by geothermal energy from Iceland’s ON Power. While Orca is not the first of its kind in the world, its size and potential have sparked expectations for a revolution in CO2 capture and storage, as well as hope for our rapidly warming planet."

The region is a hub of innovation in realms ranging from climate to food science and is home, most notably, to the Orca Plant, the world's largest carbon capture facility, which began operating last month.MATJAŽ KRIVIC |
