IFF Unveils Green Hydrogen Plant in Spain

1. Solar Power

Solar power is becoming a cornerstone in transforming perfume manufacturing into a cleaner, low-emission process. By using on-site photovoltaic systems and power purchase agreements (PPAs), solar energy is not only powering factories but also enabling the production of green hydrogen. This shift replaces traditional, fossil-fuel-dependent gray hydrogen with a renewable alternative, marking a major step forward in sustainable manufacturing.

CO₂ Reduction

In November 2025, IFF (International Flavors & Fragrances) collaborated with Iberdrola to create a solar-powered green hydrogen plant at its facility in Benicarló, Spain. This facility is designed to produce 100 tons of clean hydrogen annually, which is used in hydrogenation reactions to create over 50 key fragrance ingredients like Cashmeran and Kharismal. The project eliminates 2,000 tons of CO₂ emissions each year and serves as a model for IFF’s other global sites. Jaime Gomezflores, Senior Vice President of Global Operations Manufacturing at IFF, explained:

"The Benicarló site’s new hydrogen production capability is a major shift from traditional ‘gray hydrogen’ production methods like steam methane reforming, which relies on fossil fuels and offsite production."

Research also supports this shift. In November 2024, scientists at the Max Planck Institute of Colloids and Interfaces showcased a method to simultaneously produce green hydrogen and acetal - a key ingredient in perfumery - from ethanol using solar energy. Dr. Vitaliy Shvalagin highlighted that 87 liters of ethanol could yield 72 liters of acetal and one kilogram of green hydrogen. This dual-output approach not only reduces environmental impact but also creates additional revenue streams to offset renewable energy costs.

Cost Efficiency

Solar energy is now one of the most affordable electricity sources globally. Between December 2022 and December 2023, global solar photovoltaic (PV) module prices dropped by 50%, making solar installations increasingly accessible. In the UK, for instance, the average payback period for solar installations is expected to decrease from 8 years in 2024 to just 6 years by 2026, with annual savings estimated at $995. Solar also dominated the renewable energy sector in 2024, accounting for 81% of all new capacity added worldwide.

For manufacturers, solar energy offers a buffer against fluctuating fossil fuel prices, which have surged by as much as 65% in certain regions since 2021. Walburga Hemetsberger, CEO of SolarPower Europe, emphasized its importance:

"In these times of political uncertainty, low-cost solar power ensures energy security and competitiveness to nations across the world."

Further cost reductions are anticipated, with panel prices expected to drop by 10–15% by 2026 due to global manufacturing overcapacities.

Scalability

Solar energy systems are highly scalable, making them ideal for large-scale perfume production. IFF’s Benicarló facility exemplifies this, using solar power to drive energy-intensive chemical reactions across its entire R&D and production operations. This approach supports the creation of more than 50 key fragrance ingredients while advancing the company’s goal of achieving net-zero emissions by 2040.

When paired with co-product strategies, such as the simultaneous production of hydrogen and acetal, solar systems become even more economically viable. These dual-revenue models not only enhance financial feasibility but also align with the broader movement toward renewable energy in manufacturing.

2. Green Hydrogen

Green hydrogen is changing the way fragrance manufacturers produce chemicals, offering a renewable alternative to the fossil-fuel-heavy gray hydrogen. Gray hydrogen, typically made through steam methane reforming of natural gas, is responsible for significant CO₂ emissions - about 830 million tons annually from the global hydrogen industry. By contrast, green hydrogen, created via electrolysis powered by renewable sources like wind or solar energy, provides a low-emission option for the hydrogenation reactions needed to synthesize fragrance molecules.

CO₂ Reduction

Producing green hydrogen on-site eliminates emissions tied to fossil fuel processing and the transportation of hydrogen from external suppliers. In November 2025, International Flavors & Fragrances (IFF) introduced the fragrance industry’s first on-site green hydrogen facility in Benicarló, Spain. This step is expected to cut around 2,000 tons of CO₂ emissions annually while supporting the production of over 50 essential fragrance ingredients, such as Cashmeran and Kharismal. Jose Antonio Rojas, Vice President of Operations for Global Fragrance Ingredients at IFF Scent, highlighted the significance of this shift and outlined future goals:

"We have replaced the ‘grey’ hydrogen - manufactured using natural gas - that’s typically used in fragrance manufacturing processes with green hydrogen, produced on-site via renewable solar and hydroelectricity. Next on the agenda, we plan to directly reduce CO₂ emissions by replacing the natural gas used in the site’s steam boilers with our green hydrogen."

This shift demonstrates how green hydrogen can extend beyond its role as a chemical feedstock to also serve as a renewable heat source, transforming multiple aspects of fragrance manufacturing.

Cost Efficiency

Cost remains a key challenge. Green hydrogen currently costs between $4.50 and $12.00 per kilogram, compared to gray hydrogen’s $0.98 to $2.93 per kilogram. However, researchers are exploring ways to make it more affordable. For instance, the Max Planck Institute of Colloids and Interfaces has shown that producing 87 liters of ethanol can yield 72 liters of acetal - a valuable perfume ingredient - alongside one kilogram of green hydrogen in a single process. By selling the acetal, manufacturers can offset the cost of green hydrogen production. Dr. Vitaliy Shvalagin explained:

"To overcome that hurdle, the GH2 project is seeking to lower the cost of producing green hydrogen by manufacturing it alongside valuable chemicals like acetal which can be sold to offset manufacturing costs."

Additionally, on-site production reduces supply chain costs and transportation risks, offering greater cost predictability and operational safety.

Scalability

The ability to scale green hydrogen for large-scale manufacturing is already being demonstrated. At IFF’s Benicarló facility, a 10-year agreement with Iberdrola supports a 1.25 MW electrolyzer that produces 100 metric tons of clean hydrogen annually. This setup shows that renewable hydrogen can be integrated into existing production systems without disrupting operations. It supports both research and development and full-scale production while helping companies meet sustainability targets. This seamless integration of green hydrogen into various production stages sets the stage for broader decarbonization efforts.

Impact on Production Processes

Green hydrogen is also refining production processes. By replacing fossil fuels in key chemical reactions, it enhances operational control and reduces emissions. On-site electrolysis ensures a consistent and reliable hydrogen supply, reducing dependence on external suppliers. Furthermore, using green hydrogen in place of natural gas for steam boilers adds another layer of CO₂ reduction, moving the industry closer to fully renewable manufacturing systems.

3. Co — Product Strategies

Leveraging advancements in renewable energy, such as solar power and green hydrogen, co-product strategies aim to address the steep costs of green inputs by producing multiple valuable outputs simultaneously. This method turns costly waste into revenue-generating by-products, helping offset production expenses while advancing efforts to decarbonize and modernize fragrance manufacturing.

Cost Efficiency

The economic logic of co-product strategies is straightforward. Past examples highlight how generating both fuel and high-value chemicals can make green production more financially viable. For instance, selling co-products like acetal to fragrance and pharmaceutical companies helps offset the price gap between green hydrogen, which costs between €4.50 and €12.00 per kilogram, and traditional gray hydrogen, priced at €0.98 to €2.93 per kilogram.

The fragrance industry already benefits from co-product strategies in other sectors. Take the juice industry, which produces over 100,000 tons of orange oil and limonene as by-products each year. Similarly, the pulp industry generates turpentine, which accounts for about 15% of all fragrance materials. These examples demonstrate how co-products can lower raw material costs while aligning with circular economy principles. This approach integrates seamlessly with renewable production models at scale.

Scalability

By reducing input costs, co-product strategies also make large-scale applications more feasible. A notable example is Gucci’s April 2023 launch of "Where My Heart Beats", the first globally available fragrance made with 100% alcohol derived from recycled carbon emissions. This project utilized LanzaTech’s CarbonSmart technology, which captures and ferments steel mill waste gases to produce high-purity ethanol. Dr. Shimei Fan, Coty’s Chief Scientific and Sustainability Officer, led this initiative as part of Coty’s commitment to reducing absolute CO₂ emissions by 30% by 2030. This example shows how co-product strategies can support luxury-scale production while meeting ambitious environmental goals.

Impact on Production Processes

Adopting co-product strategies requires a fundamental shift in production workflows. Facilities must handle a variety of materials with exceptional precision. For example, automated bottling lines demand dosing accuracy within 1%, and robust CIP (Clean-in — Place) systems are essential to prevent cross-contamination. Producing inputs like green hydrogen on-site not only reduces reliance on unstable external supply chains but also improves cost predictability and Life Cycle Assessment scores for final ingredients. This approach transforms fragrance manufacturing from a linear process into a circular system where every output has purpose and value.

4. Biotechnology and Efficiency Improvements

Biotechnology relies on living organisms to produce fragrance molecules, offering a low-energy alternative to traditional methods. Unlike chemical synthesis, which requires high temperatures and pressures across multiple steps, biotechnology operates efficiently under mild conditions. This approach not only conserves energy but also aligns with the push toward renewable practices by significantly cutting emissions and energy use.

CO₂ Reduction

The environmental benefits of biotechnology are clear. Each year, approximately 1,650 tons of fragrance materials are produced globally using biotechnological methods, contributing to notable carbon savings.

Cost Efficiency

Biotechnology isn’t just about sustainability - it’s also about economic stability. Microbial biosynthesis enables the production of pure fragrance compounds on an industrial scale, bypassing the challenges tied to plant-based extraction, such as crop failures, weather fluctuations, and geopolitical issues. Unlike slow-growing aromatic plants, bacteria and yeast grow rapidly and deliver higher yields with simpler recovery processes. A prime example is Firmenich’s 2014 launch of "Clearwood", developed in partnership with Amyris. This was the first large-scale biotech-derived perfumery ingredient, providing a stable alternative to patchouli oil, which often faces supply chain instability. Additionally, biotech methods use far less land and water compared to traditional farming of aromatic crops.

Scalability

Scaling biotechnological solutions is essential for the industry’s renewable ambitions. The biodegradable microencapsulation market is projected to grow from $283 million in 2025 to $601 million by 2034, with efficiency improvements increasing from 65% to 88% over the past five years. However, current challenges remain. Biotech options are still 25–35% more expensive than synthetic alternatives, have shorter shelf lives of 12–18 months compared to 24–36 months for synthetic products, and require about 15% higher distribution costs due to cold chain logistics. Additionally, some biodegradable capsules may degrade prematurely in tropical climates, posing further challenges.

Impact on Production Processes

Incorporating biotechnology into production workflows supports the industry’s renewable shift. Transitioning to biotech processes often requires rethinking traditional workflows. For instance, decarbonizing electricity for biotech operations is simpler and less expensive than decarbonizing the high-temperature steam needed for chemical synthesis. Moreover, the mass balance approach allows companies to integrate renewable feedstocks into current systems without requiring new infrastructure, enabling reduced emissions to be attributed to specific products. With identical quality and performance to their conventional counterparts, biotech ingredients can be seamlessly adopted by fragrance houses.

Advantages and Disadvantages

Renewable methods in fragrance manufacturing come with their own set of benefits and challenges. Let’s break down some key approaches and their trade-offs.

Solar power is highly effective for reducing carbon emissions through Power Purchase Agreements, making it a scalable solution for facility operations. However, adapting steam-based chemical processes to use renewable heat remains prohibitively expensive.

Green hydrogen offers a significant reduction in CO₂ emissions, as illustrated by IFF’s facility in Benicarló. Despite its potential, cost remains a major hurdle - producing green hydrogen costs between €4.50 and €12.00 per kg, while fossil-based gray hydrogen ranges from €0.98 to €2.93 per kg. Dr. Vitaliy Shvalagin notes that, although green hydrogen has a simpler production process, it’s far more expensive than its fossil-based counterpart.

Co-product strategies, using a mass balance approach, provide a practical and cost-efficient way to reduce emissions. A notable example is BASF and Givaudan’s September 2025 initiative, which cut carbon footprints by 10–15% by incorporating renewable feedstocks into existing production lines. This "drop-in" method avoids the need for new infrastructure, addressing the fact that over 95% of fragrance emissions originate from raw materials and upstream production.

Biotechnology offers an energy-efficient way to create high-value molecules under mild conditions. However, scaling this method remains a challenge. With an annual capacity of just 1,650 tons, biotechnology falls far short of the industry’s 640,000-ton demand. Additionally, higher production costs make it less economical for widespread use.

Here’s a snapshot of how these approaches compare in terms of CO₂ reduction, cost efficiency, scalability, and production impact:

Currently, 76% of the fragrance industry’s 640,000 annual tons come from petrochemicals, while only 24% of materials are both fully renewable and biodegradable. By combining these methods, the industry can take meaningful steps toward reducing its reliance on fossil-based inputs and achieving broader decarbonization goals.

The Shift Toward Sustainability in Fragrance Production

The fragrance industry is standing at a critical juncture. With about 76% of the 640,000 tons of perfumery ingredients produced annually still derived from petrochemical sources, transitioning to renewable energy is no longer optional - it’s essential for both the planet and the industry’s future.

Several renewable energy strategies are already leading the way. For instance, IFF’s Benicarló facility demonstrates the potential of green hydrogen. Producing 100 tons of green hydrogen annually, this initiative has cut 2,000 tons of CO₂ emissions while supporting over 50 essential fragrance reactions. This facility highlights how renewable energy can revolutionize production. Dr. Vitaliy Shvalagin emphasized that leveraging co-products from chemical processes could help counterbalance the higher costs associated with green hydrogen.

Another promising approach is the mass balance method. By seamlessly incorporating renewable feedstocks into existing production lines, this strategy addresses over 95% of fragrance-related emissions, making it a game-changer for the industry.

Beyond energy, ingredient sourcing is undergoing a transformation. Regenerative agriculture and innovative extraction methods are reshaping how ingredients are gathered. A standout example is Intact Regenerative’s facility near Orléans, France, which produces perfume alcohol from legumes. This process uses 75% less water and cuts emissions by more than 80%. Similarly, Valentino’s "Private Talk" fragrance, launched in February 2025, employs Osmobloom technology. This cutting-edge method extracts ingredients using only air - eliminating the need for water or solvents - to create a more sustainable production process.

These advancements are setting the stage for the fragrance industry to achieve its ambitious 100/100 goal: 100% renewable and biodegradable materials by 2030. By combining on-site renewable energy, smart co-product strategies, and innovative extraction methods, the industry is redefining its environmental footprint and moving toward a more sustainable future.
