As the globe moves toward a net-zero carbon economy, green hydrogen is becoming an essential component of clean energy transition. Green hydrogen differs from traditional hydrogen sourced from fossil fuels in that it is produced by electrolyzing water, without producing greenhouse gases, with renewable energy sources (solar, wind, hydropower). Therefore, green hydrogen is an excellent fuel source with a very low carbon footprint. There are several technical, financial, and infrastructure obstacles to mainstream commercialization of green hydrogen. Addressing these obstacles will require significant research and development (R&D), and increasingly, partnership/collaboration has emerged as an important and prominent strategy to stimulate innovation in the sector.
Why Green Hydrogen Matters
Hydrogen is a flexible energy carrier applicable in power generation, transport, and industrial sectors. Green hydrogen is particularly viewed as important for decarbonizing hard-to-abate sectors such as steel, cement, and shipping. The IEA estimates that green hydrogen production will need to expand from 0.01 million tonnes in 2020 to over 90 tonnes by 2030 in order to meet global climate goals. To achieve this exponential growth, we will need to improve electrolyzer efficiencies, bring down costs, resolve storage issues, and establish supply chain systems.
The Role of R&D in Green Hydrogen
The green hydrogen value chain is complex and includes renewable electricity generation, electrolyzer manufacturing, storage, transport, and applications in the end-use stages of the value chain. Each stage has technological challenges:
- Electrolyzer efficiency: The current technologies such as proton exchange membrane (PEM) and alkaline electrolyzers have significant energy input requirements increasing costs for hydrogen production.
- Durability and reliability: Electrolyzers will be required to run thousands of hours, in a variety of operating conditions, and remain free from any performance degradation.
- Hydrogen storage and transport: Safe and cost-effective approaches for hydrogen compression and liquefaction and settings of transport are still under development.
- Integration with renewables: Intermittency of solar and wind based sources would require smart grid solutions and energy management systems to be advanced.
Investments in R&D aim to address these challenges that emphasize improvements in materials, scalable manufacturing strategies and the development of innovative storage solutions.
Collaboration as a Catalyst
No one organization can solve all the green hydrogen challenges. Collaboration through R&D partnerships involving governments, research institutions, energy companies, and technology start-ups will enable organizations to bring together expertise, share costs and financial risks, and help accelerate innovation. There are several advantages of partnership:
- Sharing risk and investment: New technology development involves substantial capital expenditures. Organizations can share development costs and reduce financial risk through collaboration.
- Accessing expertise and facilities: Organizations can benefit from systems that give them access to advanced labs, pilot plants, and expertise that a single organization may not have access to.
- Accelerating commercialization: Joint ventures and alliances can increase the speed of lab scale development of an innovation into commercialization of a market-ready product.
Leading Global Partnerships
Recent years have produced several notable R&D collaborations regarding green hydrogen, demonstrating a world commitment to green hydrogen:
- The Green Hydrogen Catapult
Established in 2020, the Green Hydrogen Catapult is a collaboration among prominent energy sector companies and utilities such as ACWA Power, Iberdrola, and Ørsted, that aims to bring the cost of green hydrogen below $2/kg in 2026, through collaborative innovation, scaling of electrolyser production, and advocating for policy changes.
- European Hydrogen Alliance
The European Union has set up borderless R&D collaborations called Hydrogen Europe. This collaboration includes universities, startups and leading companies and concerns R&D collaboration on collaborative projects around electrolyser efficiency, storage options and the integration of hydrogen with offshore wind.
- India’s National Hydrogen Mission
Green hydrogen is at the core of India’s strategic objectives, as demonstrated by the launch of the National Hydrogen Mission in 2021. This mission encourages R&D collaborations between public and private entities, focusing on developing native electrolyser sources, integrating hydrogen for industrial processes, and cost drop plans.
- Australia’s Hydrogen Hubs
Australia has developed various hydrogen hubs in which research institutions, mining companies, and renewable energy developers collaborate. The hydrogen hubs promote pilot projects, scaling, and developing hydrogen for export purposes.
Emerging Trends in R&D Partnerships
- Cross-industry collaboration
Energy companies, automotive producers and industrial users will collaborate to establish hydrogen value chains. An example is steel producers collaborating with electrolyzer manufacturers to deliver green hydrogen directly to steel facilities to help reduce carbon intensity in steelmaking.
- International R&D consortia
Green hydrogen will require uniformity, safety culture, and supply chains around the globe. International R&D consortia will help to share knowledge and speed up adoption across borders.
- University-industry partnerships
Universities can also engage in cutting-edge research on subjects such as materials science, electrochemistry, and energy systems. With joint programs and the industry, the research will be tested, validated, and commercialized quickly.
- Venture-backed innovation
Disruptive technology startups have begun to enter the green hydrogen space. Venture capital funding and incubator programs help those innovators connect to established players to deliver to market.
Challenges in Collaboration
Although promising, green hydrogen technology research and development partnerships have numerous obstacles they need to overcome:
- Concerns around intellectual property (IP): Sharing knowledge among several partners can create IP disputes to hamper innovation.
- Coordination management: With multi-party partnerships, project managers must navigate the complexities of scheduling, milestones, and budget with multiple parties.
- Regulatory uncertainties: Differing policies, subsidies, and safety standards across countries can create barriers to collaboration in joint R&D funded projects.
- Funding and commercialization: Many partnerships can list various forms of public funding that support the projects, but obtaining the financing required to transition to robust commercial deployment often requires significant capital investment from private sources.
Policy and Government Support
Governments are vital in catalyzing R&D partnerships through funding streams, tax incentives, and regulatory clarity. Notable policy initiatives include:
- R&D grants and subsidies: Funding reduces private investment risk.
- Infrastructure investment: Funding for pilot plants, hydrogen pipelines, and storage are now critical to feasibility.
- Standards and certification: Harmonization of both technical and safety standards promotes international cooperation.
- Public-private innovation programs: These demonstrate the value of structured collaboration by encouraging universities and private companies to develop co-designed technologies.
For instance, Japan, Germany, and the U.S. have developed national hydrogen strategies that address how to encourage collaborative R&D and pilot projects to exemplify rapid innovation.
Looking Forward
Green hydrogen may reshape the global energy transition space entirely. To meet the aggressive targets of governments and industry, new and innovative partnerships in research and development (R&D) will become increasingly important, and be the driving force behind scaling technologies, reducing costs, and pairing efficiencies across the integrated supply chain. As we create new pathways for collaboration we can expect:
- More sophisticated electrolyzers with significantly increased efficiencies that reduce capital costs that support scale-up.
- Integrated hydrogen ecosystems with production, storage, and end-use applications.
- Increased readiness to establish global supply chains and common safety protocols and standards.
- Increased start-up and SME activity that brings innovation and agility to the hydrogen value chain.
Moving to green hydrogen represents not only a technology challenge but a collaborative effort. The partnerships created through companies, R&D facilities, and government will define the rate at which green hydrogen transitions from niche offerings to a common energy tool. The global community can begin to create new pathways to solving problems and play a role in transitioning to a green hydrogen future through knowledge-sharing, pooling resources, and aligning strategies.
