Concentrating solar energy first emerged on the renewable vitality area just some years in the past, and critics had been fast to go on the assault. Nonetheless, followers of the expertise cast forward. Now all that onerous work is about to repay, and the EV battery provide chain may very well be a beneficiary.
At this writing, Russian President Vladimir Putin appears intent on murdering as many individuals in Ukraine as he can. Tens of millions are fleeing and in want of help. To assist refugees from that battle and others, donate to Medical doctors with out Borders or different dependable assist organizations.
The Concentrating Photo voltaic Energy Benefit
Because the identify suggests, concentrating solar energy methods acquire photo voltaic vitality that displays from fields of specialised mirrors known as heliostats, or from lengthy, curved metallic buildings known as parabolic troughs. The mirrored vitality is targeting a specialised oil, molten salt, or different transportable medium, to generate excessive warmth to be used in working numerous industrial processes.
Producing steam to run an influence plant is the first use case for concentrating solar energy, which raises the query of why not merely use photo voltaic panels to generate electrical energy. That’s a great query. The reply is that the transportation medium in a concentrating solar energy system additionally doubles as an vitality storage medium.
All else being equal, a concentrating solar energy system may retailer sufficient photo voltaic vitality to tide itself over for night-time hours, and coordinate with different renewable vitality methods to ship electrical energy on similar 24/7 functionality anticipated of fossil and nuclear energy vegetation.
Whereas the Obama administration promoted next-generation nuclear expertise, it additionally counted on concentrating solar energy to showcase the flexibility of US innovators to push the renewable vitality envelope into 24/7 territory.
On the time, critics charged that concentrating solar energy methods had been too costly and complicated, however the prize of 24/7 dispatchability was a tempting one again then, and now Russia’s homicidal rampage by Ukraine has raised large new purple flags over the safety dangers inherent in each fossil and nuclear vitality methods.
Nuclear Vitality vs. Concentrating Photo voltaic Energy
Particularly, Russia’s assault on nuclear services in Ukraine demonstrates how simple it may be for one rogue nation to threaten a whole continent with widespread catastrophe. The unprovoked conflict has undercut the argument that nuclear vitality ought to play an important function in speedy world decarbonization.
The nuclear argument had gained pressure because the 2015 Paris Settlement on local weather change took form, with prime US investor Invoice Gates main a pack of A-list financiers within the newly hatched Breakthrough Vitality Coalition and its sister agency, Breakthrough Vitality Ventures.
Breakthrough’s deal with nuclear vitality is not any shock, contemplating that Gates can be a backer of the nuclear agency TerraPower. Nevertheless, in tune with Breakthrough’s broader mission of vitality innovation, Gates was additionally an early backer of the concentrating solar energy startup Heliogen.
So, how do the 2 Gates ventures stack up? TerraPower’s modular design nonetheless seems to be in the “experiment” section. A proposal is within the pipeline to construct the primary one in Wyoming with a hearty help from the US Division of Vitality, however critics have questioned whether or not new designs can keep away from the associated fee and effectivity points which have bedeviled the nuclear business within the US.
Even when all goes based on plan will probably be years, maybe a long time, earlier than the modular design angle pitched by TerraPower can show itself available on the market.
In the meantime, Heliogen already seems to be one leap forward.
The Modular Resolution
When it comes to the modular strategy to manufacturing, Heliogen may very well be the TerraPower of the concentrating solar energy area, solely with a a lot higher likelihood of bringing its modular enterprise mannequin to market.
The primary backside line subject with each nuclear and concentrating solar energy is that prices are greater when every venture will depend on site-specific tailoring. If modular elements can manufactured in amount at a central location and shipped out, prices ought to drop considerably.
For concentrating photo voltaic, that opens up the potential for co-locating photo voltaic operations with industrial services, and that’s what Heliogen seems to take into consideration.
Heliogen first crossed the CleanTechnica radar again in 2019, when it burst out of stealth mode.
“Whereas TerraPower has been pitching nukes, the Heliogen analysis group has been hammering away in deepest secrecy at its analysis facility in Lancaster, California, with the intention of growing a concentrating solar energy system that may ship temperatures of greater than 1,000 levels Celsius,” we noticed. “Studying between the strains of Heliogen’s first ever press launch, that places the brand new photo voltaic system in direct competitors with fossil fuels for high-heat industrial processes together with cement and metal manufacturing.”
How Does It Work?
Heliogen’s contribution to the concentrating solar energy area is the appliance of excessive effectivity supercritical carbon dioxide expertise. The essential thought is to shrink the dimensions of elements, decrease prices, and promote modularity.
Final December was a busy month for Heliogen. The corporate went public and finalized the phrases of a $39 million Vitality Division award, geared toward supporting the corporate’s plans for its first new business scale manufacturing plant, to be situated in Lengthy Seashore, California.
“The Firm will apply the funds acquired from the DOE in direction of a commercial-scale facility leveraging its AI-enabled concentrated photo voltaic expertise,” Heliogen defined. “Particularly, the DOE funds will help the implementation of Heliogen’s distinctive concentrated photo voltaic expertise which {couples} its AI-powered heliostat area with a supercritical carbon dioxide (sCO2) energy cycle.”
“Steam-based energy cycles are sometimes utilized in thermal vitality vegetation to transform warmth into electrical energy, however superior sCO2 cycles will attain greater efficiencies at decrease price with a smaller footprint and lowered water use,” Heliogen added. “With its quite a few superior applied sciences, the Heliogen system is anticipated to unlock the manufacturing of low-cost, close to 24/7 carbon-free electrical energy, highlighting the potential for concentrated photo voltaic expertise to energy business and speed up the clear vitality transition in america and past.”
The EV Battery Angle
Heliogen introduced the launch of preliminary work on its new manufacturing facility final month, and it gained’t be lengthy earlier than we discover out whether or not or not this factor works. The corporate is aiming for a Q3 startup this 12 months, and the primary heliostats to roll off the meeting line are already slated for Heliogen’s first venture, which seems to be a mine in Boron, California, below the Rio Tinto umbrella.
As described by Rio Tinto, the Boron mine is one among solely two “world class” websites for borates on this planet. The mine has been working since 1927 and concentrating solar energy will give present it with a possibility to scale back its carbon emissions by about 7%.
That’s excellent news for electrical car followers who’re involved in regards to the carbon footprint of the EV supplies provide chain.
In an fascinating twist, final 12 months Rio Tinto additionally revved up an indication facility on the Boron website, geared toward recovering lithium from waste rock. If all goes based on plan, the mine will assist contribute battery-grade lithium to the home EV provide chain, so keep tuned for extra on that.
