City Council receives 43-page report, ‘Port of Benicia – Facilities and Infrastructure Modernization Plan’
Benicia City Council learned about improvements needed to maintain the Port of Benicia, as well as potential work that could attract more seafaring customers – to the cost of $700 million.
Background: The City of Benicia received a $750,000 grant to develop a Port of Benicia Facilities and Infrastructure Modernization Plan. The consultant doing the work, GHD, presented parts of the plan to councilmembers at a city council meeting Tuesday. The grant came from regional government agencies, the Metropolitan Transportation Commission and the Association of Bay Area Governments.
The main takeaways: The port and surrounding area need work to maintain operations into the near future, like structural improvements to the pier, stormwater infrastructure, and nearby roads and intersections used by truck traffic related to port activities.

After “years of disrepair,” the City Council on Tuesday…
After “years of disrepair,” the City Council on Tuesday approved spending up to $1.6 million to fix and maintain the city’s aging solar panels for the next five years. There’s a caveat.
Background: The city has 10 solar arrays installed about 15 years ago to power a portion of city operations. Parts of the system have been broken for years, according to City Manager Mario Giuliani. The system of panels next to James Lemos Swim Center is completely down, for example. The only good they provide is shade until they’re fixed.
Giuliani stressed the need to get these fixed ASAP, saying “we’re losing money just from the four sites that are off.” Together, the system produces about $770,000 worth of electricity a year.
“By the way,” Giuliani said, City Hall, the Clock Tower and the Police Department building are on collateral for the loan to cover the cost of construction of the arrays back in 2011, which the city continues to pay off every year.
BenIndy highly recommends ‘Jumping Into Solutions’
By Pat Toth-Smith, November 7, 2023
I am pleased to announce the locally produced You Tube and Spotify podcast channel, “Jumping into Solutions” has three new episodes to help you GO ELECTRIC in your home. We feature local Benicians’ who have started on their own paths of reducing their carbon footprint by making their homes as energy efficient as possible. The episodes feature local co-hosts Kathy Kerridge and me, Pat Toth-Smith, neighbors and experts in their fields who answer complicated questions like, how does the technology work and can I afford it?
Switch Is On to Electric Heat Pumps | EP. 2
Here’s everything that you need to know about switching to the energy-efficient, electric water heater pumps and electric home heating/cooling pumps. This episode clears up the questions of how new electric heat pumps work, does it cost a lot of money to install, and can I remove my gas system after installing them?
BENEFITS of Home Solar Panels & Solar Battery Storage | EP. 3
This episode talks about the benefits of going solar at a time when reducing our carbon footprint is vital; it answers questions about affordability, rebates, how solar works with your energy provider, solar battery storage functions and how to use your battery in the event of a power outage? And discussions about the new PG&E changes involving NEM 2 and NEM 3.
Switch to Electric Induction Stoves from Gas Stoves | EP. 4
Did you know, induction electric stoves are more energy efficient than gas and electric stoves and can boil water or heat up food faster than both. They also are healthier than gas stoves because gas leaks can occur when idle and/or outgassing when in use. Many adverse health effects are related to this outgassing of toxic gasses that includes Benzene, Carbon Dioxide and also PM2.5, which can cause resp illnesses and other more serious diseases. Induction electric stoves are safer than gas or electric because energy is transferred to the pot by an electromagnetic field, and the stove turns off after the pot is removed. It answers questions like: How does induction work? What toxic, green-house gasses are released? Are there rebates?
Using air reduces overhead and materials costs compared with hydrogen storage.
Compressed air is stored during surplus times and fed back during peak usage.
Two new compressed air storage plants will soon rival the world’s largest non-hydroelectric facilities and hold up to 10 gigawatt hours of energy. But what is advanced compressed air energy storage (A-CAES), exactly, and why is the method about to have a moment?
Compressed air is part of a growingly familiar kind of energy storage: grid-stabilizing batteries. Like Elon Musk’s battery farm in Australia and other energy overflow storage facilities, the goal of a compressed air facility is to take extra energy from times of surplus and feed it back into the grid during peak usage.
Here’s how the A-CAES technology works: Extra energy from the grid runs an air compressor, and the compressed air is stored in the plant. Later, when energy is needed, the compressed air then runs a power-generating turbine. The facility also stores heat from the air to help smooth the turbine process later on.
While the efficiency of similar systems has hovered around 40 to 50 percent, the new system from Hydrostor, a major global leader in building hydroelectric storage, reportedly reaches 60 percent, according to Quartz.
Hydostor will store compressed air in a reservoir that’s partly filled with water to balance out the pressure. The whole system will hold up to 12 hours of energy for the grids where the two plants are planned. (The first plant will be built in Rosamond, California, while the second location is to be determined.)
Hydrostor energy storage facility
Why branch out from hydrogen to compressed air? While hydro storage is a great part of the global energy scene, storing massive amounts of water requires a ton of infrastructure that Hydrostor says uses a lot of energy it’s ultimately trying to save. That makes intuitive sense if you think about the relative force of water compared with even heavily pressurized air.
“Pumped hydro accounts for around 95 percent of the world’s grid energy storage and gigawatt-capacity plants have been in operation since the 1980s. The problem is that you need a specific type of location and a staggering amount of concrete to build a pumped hydro plant, which works against the goal of reaching net zero. Rotting vegetation trapped in dams also contributes to greenhouse gas emissions. Meanwhile, the biggest mega-batteries built so far are only in the 200 MW/MWh range, though installations bigger than 1 GW are planned.
Recharge reports that companies have built smaller existing CAES facilities over naturally occurring salt caverns. In contrast, Hydrostor will be digging new caverns to use for its larger facilities in California, just as engineers are constructing huge salt caves in Utah to store hydrogen.
The first of Hydrostor’s two plants is set to open in 2026, and the company says its system will last for about 50 years—making it a lot longer-lived than almost any energy storage of its kind. The near future of energy is likely made of a dozen different solutions that are all suited to different environments and situations, so adding compressed air to the portfolio simply makes sense.
