The transition to renewable energy sources is a critical step towards a sustainable future. However, the intermittent nature of renewable energy sources such as wind and solar poses a significant challenge to the stability of power grids. This is where the role of energy storage systems, particularly Vanadium Redox Flow Batteries (VRFBs), becomes crucial. VRFBs are increasingly recognized as a key technology for integrating renewable energy into power grids and ensuring a reliable, uninterrupted power supply.
Vanadium Redox Flow Batteries operate on a simple principle. They store energy in two tanks filled with a liquid vanadium electrolyte solution. The energy is released or stored by pumping the electrolyte across a membrane where a chemical reaction takes place. This process can be repeated thousands of times without significant degradation, making VRFBs a highly durable energy storage solution.
One of the most significant advantages of VRFBs is their scalability. The amount of energy they can store is limited only by the size of the electrolyte tanks. This makes them ideal for large-scale, grid-level energy storage. They can be scaled up to store energy from large wind farms or solar power plants, smoothing out the supply and demand imbalances caused by the variable nature of these renewable energy sources.
Another key advantage of VRFBs is their long lifespan. Unlike other types of batteries, VRFBs do not degrade significantly over time. This is because the vanadium electrolyte does not wear out or degrade, unlike the materials used in other types of batteries. This means that VRFBs can provide reliable energy storage for decades, making them a cost-effective solution in the long term.
Moreover, VRFBs offer a high level of safety. The vanadium electrolyte is non-flammable and non-explosive, reducing the risk of accidents. Furthermore, because the energy is stored in a liquid form, there is no risk of a sudden release of energy, as can happen with other types of batteries.
In addition to these advantages, VRFBs also have a high efficiency rate. They can charge and discharge at close to 100% efficiency, meaning that almost all the energy stored in them can be used. This is particularly important for renewable energy integration, as it ensures that as much of the generated energy as possible is used.
The role of VRFBs in renewable energy integration is becoming increasingly important as the world moves towards a more sustainable energy future. They offer a reliable, scalable, and safe solution for storing energy from renewable sources and ensuring a stable power supply. As the technology continues to develop and become more cost-effective, VRFBs are set to play a crucial role in the transition to renewable energy.
Hopefully some of the projects include batteries and some of those batteries are vrfb.

South Africa expects more than 5,500 megawatts (MW) of additional renewable energy projects to come online by 2026, electricity minister Kgosientsho Ramokgopa said on Tuesday.
He added that 66,000 MW of wind and solar projects were under development across the country.
South Africa is in the midst of its worst electricity crisis ever, with households and businesses facing hours of daily scheduled power cuts due to repeated breakdowns at state utility Eskom's ailing fleet of coal power stations.
But some analysts have started to turn more optimistic that the government will make progress in reducing the intensity of the power cuts, helping the rand currency recover from a record low touched on June 1.
I sometimes read things I'm going to post and know immediately how certain parties will use it to push a narrative but I'm not sure I would like to pick and choose what to post as it's out there just waiting to be found anyway.
I'm comfortable with what I've invested in BMN, happy with the operational progress and have time on my side to wait for the investment to bare fruit. I learnt early on with investing that my personal investment horizon will never, ever align with how a business actually progresses. I also found that moaning on a board every day made absolutely no difference to a share price but it did affect my mental health as I would get more angry, frustrated and sad. I'm now in a place where it doesn't affect me, which is great :)
I know people will potentially be concerned about the fact it uses a 10th of the vanadium a normal vrfb uses but as vanadium is the major cost of vrfb batteries then it could really accelerate the take up of these solid state batteries. If they are then able to then extended to other applications like ev's the extra volume created by increased usage would more than cover a lower v content in the batteries.
So although these batteries use 1/10th the vanadium of vrfb's this technology opens up more everyday uses so increasing the potential market further according to the MK Plus website

The IRP 2019 does not include an allocation for nuclear besides 1 860 MW for Koeberg’s life extension and states only that preparations for a nuclear build programme to the extent of 2 500 MW should commence “at a pace and scale that the country can afford”.
The department tells Engineering News that nuclear is included as one of the technologies in the IRP 2019 that the technical model should consider.
It also claims that the policy proposes that the nuclear power programme be implemented at a modular scale, as opposed to a fleet approach and that technological developments in the nuclear space should be taken into account.
Several commentators have already raised concerns about the potential content of the draft IRP 2023 in light of Mantashe’s ongoing push for additional nuclear, gas and coal in the future plan, despite several studies showing that the least-cost electricity mix would be based on solar and wind, supported by flexible generators and storage.
Nevertheless, the Democratic Alliance’s Kevin Mileham lambasted the delay in the publication of the IRP, which he said formed part of a pattern of under delivery by Mantashe when measured against the performance agreement targets that had been set for him in the area of energy, and which the Minister had signed.
These targets ranged from finalising a just energy transition framework, facilitating the procurement of new generation and supporting a recovery in Eskom’s energy availability factor, to ensuring Eskom’s unbundling and the security of supply of liquid fuels.
“The reality is he [Mantashe] is failing on just about every single measure,” Mileham noted.

Mineral Resources and Energy Minister Gwede Mantashe has pulled back from his statement that the release of the revised Integrated Resource Plan, which he has dubbed IRP 2023, is imminent, revealing during his Budget Vote on Tuesday that the draft will be presented to Cabinet only in the second quarter of this financial year.
Government’s financial year runs from the start of April to the end of March, implying that the presentation to Cabinet will be made between July and September.
In an earlier briefing of lawmakers on May 9, Mantashe acknowledged that government had failed to meet its initial deadline of March for the release of the draft IRP, but asserted that “it is going to happen now”.
Speaking in Parliament on May 16 against the backdrop of intense loadshedding, Mantashe again described the IRP as South Africa’s blueprint policy for electricity generation and confirmed that it was currently under review.
The department confirmed with Engineering News that the draft IRP would go through the government’s economic cluster for inputs before it progressed to Cabinet.
"Once the Cabinet approves the revised IRP, the normal public policy development process will be undertaken.
"The process entails consultations with the mining and energy sector, interested and affected parties and South Africans at large.
"It is anticipated that the final revised IRP will be approved and Gazetted for implementation during the course of the 2023/24 financial year."
Mantashe added that, while the review was under way, government would continue to procure additional electricity informed by the existing policy.
He announced that the following procurement programmes would be launched during the current financial year:
Bid windows seven (BW 7) and eight (BW 8) of the renewable procurement programme, at 5 000 MW apiece, with a request for proposals (RFP) for BW 7 to be issued in the second quarter and for BW 8 in the fourth quarter;
Further RFPs for a combined 1 230 MW of battery storage to be issued in the second and fourth quarters;
An RFP for 3 000 MW of gas-to-power in the second quarter; and
An RFP for the procurement of 2 500 MW of nuclear energy in the fourth quarter.
In her address, Deputy Minister Dr Nobuhle Nkabane said the department had recently drafted a framework that would “ensure that the procurement of the 2 500 MW of nuclear energy is completed by the year 2024”.
While the proposed nuclear procurement was not surprising given Mantashe’s vocal support for the technology, the firm RFP deadline implied that government was likely to include a specific allocation for nuclear in IRP 2023.
“Unlocking the national grid at speed and scale is key, in the PCC’s view, to vast swaths of the transition (including many “just” elements), and funding in the implementation plan should be aligned with National Treasury’s evolving policy, paying particular attention to the need to simplify the public-private partnerships for financing of infrastructure.”
SOCIAL OWNERSHIP MODELS
Olver also stressed that the PCC was keen for new social ownership models to be facilitated in the generation sector, as new renewable energy, battery storage and other peaking capacity was introduced.
He said that various stakeholders, but especially labour, were concerned about the dominant role of the private sector in the evolving electricity supply industry and that alternative ownership models should also be “nursed” under the JET-IP.
The report notes that, while the JET-IP flags the importance of energy affordability for development, it says very little about how this will be secured through social ownership models, notwithstanding the opportunity that will be created by the PCC’s estimate that between 50 GW and 60 GW of new renewables will be required by 2030 to stabilise South Africa’s electricity supply.
“[It] is important to consider how the JET-IP could better address the ownership balance in the context of institutional constraints in terms of electricity generation, financing, and a lack of transparency.”
The PCC acknowledges that social forms of ownership are unlikely to match the scale of private investment in the coming five to ten years.
“Nevertheless, even if relatively small, the coming five-year window should see some increased focus in an implementation plan that allows nongovernmental organisations and unions to work to deliver this – while government creates a conducive environment for the creation, operation and funding of wider ownership models.”
Meanwhile, Olver was relatively sanguine about the ability of South Africa to meet its decarbonisation commitments, despite the likelihood of the coal decommissioning schedule being revised in light of intense loadshedding and the low prospect of alternative capacity being added in time to close the supply gap.
He indicated that the poor performance of the coal fleet meant that South Africa was already in line with the decarbonisation trajectory outlined in its Nationally Determined Contribution and that delaying the dead-stop date of certain units was, thus, almost immaterial.
That said, the least-cost solution for South Africa would be to close the coal units in line with their dead-stop dates, as it was extremely expensive to extend their life further.
In addition, once South Africa added sufficient new renewables, storage and peaking capacity, Olver believed there might be potential to “opportunistically” close more expensive coal units down ahead of their official decommissioning dates.

The Presidential Climate Commission (PCC) is recommending that alternative investment models, including public-private partnerships (PPPs), be explored to expand and strengthen South Africa’s electricity grid “at speed and scale”, given the centrality of the grid to unlocking the energy transition, as well as the just components of the transition.
However, it also stresses that there is no intention to privatise the National Transmission Company of South Africa (NTC), which is in the process of being established as a separate entity under Eskom Holdings.
Instead, the proposal is that the private sector help finance, build and operate new grid infrastructure under the ownership and control of the NTC.
“Grid capacity is a national priority to solve, not only for our transition needs, but also for our short-term emergency to solve loadshedding,” the PCC says in ‘A Critical Appraisal of South Africa’s Just Energy Transition Investment Plan’, or JET-IP.
The report, which has been drafted following three months of intensive public consultation with labour, business and community stakeholders, argues that the grid should be the key focus of the JET-IP in the coming five years and that the implementation plan should be fully aligned with Eskom’s Transmission Development Plan, or TDP.
The JET-IP implementation plan is currently being finalised and is expected to be published soon, drawing on the recommendations arising from the consultation process, during which stakeholders also agreed that the just elements of the plan had been inadequately prioritised and that sections on skills development, economic diversification, mine rehabilitation and worker support should be substantially reviewed, and investments increased.
In addition, the PCC recommends that the electric vehicle and green hydrogen components of the plan be located within a national industrial strategy which sets out fiscal incentives and enabling infrastructure to grow the sectors, rather than to use the JET-IP as a replacement for such policy support.
On the transmission network, the PCC says the JET-IP needs to clearly indicate how the grid expansion will be financed, despite the constraints on public sector funding.
“It may be worth exploring alternative models for new investments in the State-owned transmission grid,” PCC secretariat executive director Dr Crispian Olver said at the report’s release.
The report notes that PPP funding models, with appropriate risk sharing, have been proven effective globally and in Africa and “can be a highly bankable, solid credit investment for the private sector”.
It also notes that National Treasury called for a PPP transmission development model to be explored urgently in the February Budget.
