First in USA: Tracy facility removes C02 from air, encases it in concrete
Tracy C)2
Stacks of trays of limestone powder that is being used to extract CO2 from the air.

 Growth will help clean the air.
That’s the idea behind Heirloom — the nation’s first commercial Direct Air Capture facility that celebrated its completion with a ribbon cutting Thursday in Tracy at 4750 South Holly Drive.

In a nutshell, the facility will capture CO2 from the atmosphere which is then embedded permanently in concrete.

Heirloom’s facility was constructed with union labor, is powered by renewable energy, will capture, store, and deliver CO2 removal credits.

Heirloom will work with partner CarbonCure so the CO2-enriched concrete is laid in the foundations of buildings and structures, with the added benefit of creating stronger concrete.
The Tracy facility was formally unveiled with US Secretary of Energy Jennifer M. Granholm, California Lieutenant Governor Eleni Kounalakis, San Joaquin County Board of Supervisors’ Chair Robert Rickman, and other officials in attendance.

 “Tracy is no stranger to the impacts of climate change, so we are excited to make history by welcoming Heirloom’s first commercial direct air capture facility to our community,” said Mayor Nancy Young.

“Not only have they brought innovative technology to Tracy to scrub our air of carbon, but they have also sponsored the planting of additional trees to enhance our urban forest. We are proud to be part of the solution when it comes to the impacts of climate change, as advancing ‘green projects’ and supporting climate initiatives are consistent with the goals set by our City Council to improve our quality of life here in Tracy.”

 The project generated 50 construction jobs.

It will initially yield 15 permanent, full-time green operations and maintenance jobs.

The Tracy facility is expected to pave the path for similar green technology careers around the country. .

By mid-century, experts indicate there will be a need to remove billions of tons each year – equivalent to 10-20% of today’s annual global emissions – in order to keep global temperature rise below 1.5°C.

Even if emissions stopped tomorrow, the CO2 that’s already in the atmosphere will take thousands of years to dissipate – all the while the planet will continue to warm.

Heirloom will permanently remove CO2 from the atmosphere. Direct Air Capture is the best solution available to do this today.

The process takes CO2 directly from the atmosphere, and then permanently and safely store the CO2 underground or in materials like concrete.

Limestone is made up of calcium oxide and CO2.

When CO2 is removed from limestone, the remaining calcium oxide acts like a sponge – absorbing CO2 so it can return to its natural limestone state.

The Heirloom technology accelerates the natural property of limestone, reducing the time it takes to absorb CO2 from years to 3 days.

It heats limestone mineral powder in a renewable-energy powered kiln to remove the CO2.

Heirloom’s partners then permanently and safely sequester the CO2 in deep geological reservoirs, or in long-lasting materials like concrete.

Once the CO2 is removed, the mineral powder is spread onto vertically-stacked trays and “treated” to optimize its ability to uptake CO2 in different environmental conditions.

Like repeatedly wringing a sponge, the process loop the limestone mineral powder through the system to continuously suck CO2 from the atmosphere – a cyclic process that not only lowers costs but also reduces how much limestone must be mined.

AVERAGE MANTECA PG&E BILL $237 HIGHER THAN MID
PG&E costs up $66 a month thanks to massive hikes in ‘24 while MID customers saw increases of several dollars
substation
The PG&E substation off of Elm Avenue that SSJID is seeking to acquire along with the rest of the distribution system within district boundaries.
PG&E customers in Manteca using 750 kilowatt hours of electricity each month are now paying $237 more a month than those households using the same amount of power in Modesto. The reason? Modesto is served by the Modesto Irrigation District.
