]]>Translation of Accio’s post below:
This Thursday we discovered first-hand Jolt Activated Electrodes, one of the most promising Catalan ‘deep techs’ in Europe and recognized as a Catalonia Exponential Leader in 2023, in a new edition of ACCIÓ’s ExponentialOpenDays.
Born as a spin-off from ICIQ, the company has developed an activated electrode technology that allows the production of green chemicals in a more efficient, durable and affordable way. An innovation that places the company at the forefront of the energy and green chemicals transition.
During the visit, Arturo Vilavella, COO and co-founder of Jolt, shared his vision of the future, the challenges of scaling an impactful technology and the international expansion plans of a company that already operates from its first plant in Barcelona and is collaborating with international partners to accelerate its growth.
The event, attended by around thirty Catalan companies, included a question and answer session, a guided tour of the facilities and a final networking session among all participants.

The signing ceremony was attended by Mr. Arturo, representing Jolt Solutions; Dr. Khodran Al-Zahrani, CEO of Dyar Al-Safwah; Mr. Abdulrahman Al-Qahtani, CEO of Jolt Green Chemical Industries; and Dr. Said Jubran Al-Qahtani, Chairman of Green Electrodes Consortium.
Statements from Participants:
Dr. Said Al-Qahtani affirmed that the plant will serve as a platform for technology localization and the empowerment of national talent, thereby strengthening the Kingdom’s position as a regional hub for green technologies. He also expressed his gratitude and appreciation to the Ministry of Energy, noting that its support and encouragement during previous visits played a pivotal role in motivating the company to bring this technology to the Kingdom and localize it.
Mr. Abdulrahman Al-Qahtani emphasized the company’s commitment to building a world-class facility that enhances the Kingdom’s role as a regional hub for advanced technologies, while Dr. Khodran Al-Zahrani expressed his delight in Dyar Al-Safwah’s participation in this pioneering industrial project with its engineering expertise.
Jolt in Saudi Arabia:
The plant will specialize in the production and refurbishment of high-performance catalyst-coated electrodes. It will also contribute to the Kingdom’s programs in green hydrogen, petrochemicals, refining, water treatment, eFuel, battery projects, water desalination, disinfection, chlor-alkali, and pipeline protection.
The plant is scheduled to commence operations in the second quarter of 2027. It will feature advanced automated production lines, dedicated research and development laboratories, and adopt environmentally friendly solutions such as wastewater reuse and solar integration. At full operational capacity, the plant will supply more than 750,000 square meters of electrodes annually.

]]>Traditionally, AWE systems have used a combination of nickel anodes and nickel Raney cathodes. The anode, typically not activated, has historically suffered from oxidation as the equipment cycles through voltage steps, resulting in a need to maintain a high baseload with limited shutdowns. This has also reduced the current density at which the equipment can operate, although lower current densities do lead to higher gas production efficiency (FIG.1).
Nickel Raney, a high-surface-area nickel coating deposited on the surface of an underlying nickel substrate, offers good levels of performance on the cathode but can be prone to early degradation. In some instances, nickel Raney may also be used on both the anode and cathode.
Most alkaline electrolyzers operate in the low current density realm (0.25A/cm2–0.5A/cm2), but there are exceptions. Some electrolyzer companies design equipment to operate at higher current densities in excess of 1A/cm2. Typically, this type of equipment uses a precious metal catalyst to achieve higher performance and must be iron-free, which can increase the cost of the stack.
When it comes to field deployment, the initial cost of the electrolyzer (including the stack) is a major capital expenditure (CAPEX) concern. However, the greatest impact on the levelized cost of H2 (LCOH) is the cost and amount of renewable electricity used in H2 production. The stack design and the components used in the stack have a big impact on this electrical efficiency. H2 project managers are often willing to pay more for original equipment if it uses less electricity per kilogram (kg) of H2 and maintains that efficiency longer (through higher-durability components, resulting in lower degradation and longer intervals between services). There is also an increasing demand for equipment with more flexibility to accommodate variable current from renewable energy sources.
FIG. 2 shows the impact of using more advanced electrodes on the specific energy consumption in kilowatt hours (kWh)/kg and kWh/normal cubic meters (Nm3). These values only consider the balance of stack (BoS), and it should be noted that there will be an effect from the balance of plant (BoP). Even so, changing the electrodes to next-generation designs can significantly reduce the energy consumption.
Newer coatings can also improve durability, even against repeat shutdown cycles as may be experienced when coupling electrolysis with renewable energy. Traditional electrodes are normally based on nickel-woven or expanded mesh. This is largely because of the limitations of older coating techniques such as electroplating, electrodeposition or thermal decomposition.
Modern coating techniquesa can coat much more complex electrodes based on nickel substrates, such as foam and felt. These higher-surface-area base materials, in conjunction with new generations of catalysts, lead to a combined effect in terms of performance advantages. The increased surface area provides an initial performance boost, and the greater catalyst deposition creates a compounded effect.
There are several new coating techniques being explored but given the scale of production demanded by gigawatt scale projects, there should be serious considerations to the cost and speed of the production. High-end, extremely high-performing electrodes can be created on a small scale by using exotic or complicated materials, or high energy-intensive or slow processes but often these cannot realistically be deployed at scale (FIG. 3).
In some cases, new coating techniquesa can scale faster and at lower cost than traditional methods, meaning they can support the gigawatt ambitions of many companies. Another key factor to increasing electrolyzer efficiency is reducing the downtime during service intervals. When possible, electrode production should occur as close to the deployed electrolyzer as possible to ensure short maintenance periods. If such a service was available, more frequent service intervals could be employed, ensuring the electrolyzer runs efficiently. Strategically distributed, small-scale modular electrode coating lines will be essential in the future.

]]>Vancouver, B.C. / Barcelona, ES | June 2, 2025: Two leading component suppliers in the field of Anion Exchange Membrane (AEM) electrolysers are teaming up to develop turnkey solutions for the faster adoption of this critical technology. Ionomr Innovations, a manufacturer of hydrocarbon-based membranes and ionomers, and Jolt Solutions, a manufacturer of nickel-based activated electrodes, signed a Memorandum of Understanding today.
The agreement involves integrating membranes and electrodes to generate knowledge which can be passed to the market to ease development activities and increase the performance, durability and ease manufacturing of AEM electrolysers. By providing thorough advice on the integration of these vital components, the end users will benefit from the wealth of knowledge generated by the companies.
The two companies have strong synergies, both recognized as leaders in the field. Both Jolt and Ionomr have already scaled production to support GW scale adoption of AEM electrolysis and can further scale as the market grows.
AEM electrolyser technology is widely recognized as the future of hydrogen production, offering the benefits of both PEM and AWE without the drawbacks. AEM technology uses no, or very low levels, of precious metals and can operate at elevated current densities giving them a smaller footprint and high Hydrogen production rate, while the membrane technology prevents hydrogen and oxygen mixing, allowing for rapid ramp rates and highly effective pairing with renewable technology.
