Green Hydrogen for Local Economic Development
Green hydrogen is rapidly gaining global prominence as a crucial energy carrier for the future. Although much of today’s discussion focuses on hydrogen production and its export potential, domestic consumption of green hydrogen offers equally significant opportunities for local economic development—strengthening municipal infrastructure, creating skilled jobs, and stimulating new economic activities along various value chains. For many African countries, abundant solar and wind resources give cities a unique advantage, positioning them not only as innovation hubs but also as centers for technology transfer, workforce training, and industrial diversification. By integrating sustainable use of green hydrogen into urban planning, municipalities can enhance energy security, attract long-term investment, and build more resilient, climate-friendly local economies—ultimately becoming key drivers in the global clean-energy transition.
To advance the exchange of best practices and accelerate strategy development between African and German cities, Connective Cities hosted its second workshop on “Exploring the Potential of the Green Transition for Local Economic Development” held on 25–27 November 2025 in Mombasa. Representatives from Mauritania, Kenya, South Africa, and Germany participated. This edition focused on improving technological readiness for green hydrogen production, addressing local implementation challenges andstrengthening regional competitiveness among other readiness issues. The discussions further emphasized the importance of involving , and integrating universities, research institutions and start-ups as key drivers of job creation and innovation.
The City of Nakuru, Kenya presented its benchmark strategy to position itself as a model green city and a leading hub for green fertiliser production within is floriculture sector, reducing import dependency and supporting the emergence of new green industries. With its proximity to the rift valley geothermal vents, Nakuru is well positioned for cost- competitive green hydrogen production. The city aims to attract pilot projects, applied research initiatives, and local and international start-ups working along the green hydrogen value chain., reinforcing its long-term vision as a regional clean-energy and innovation hub.
Kenya has adopted a national Green Hydrogen Strategy and participates in regional African hydrogen initiatives. Mombasa, as a major port city, holds strategic significance for export logistics and coastal project siting. While early national activities have focused on potential assessments and pilot sites, coastal locations like Mombasa are increasingly viewed as gateways for logistics, export-oriented hydrogen production, and coastal renewable-energy projects. The city now seeks to leverage its strategic location to establish itself as a global player in hydrogen-powered logistics and to develop the port into a logistics cluster that attracts innovative local and international investment supported by a skilled workforce.
In South Africa, the Waterberg region in Limpopo forms part of the national “Hydrogen Valley,” stretching across Limpopo, Gauteng, and KwaZulu-Natal. Mining and industrial operations in the Waterberg–Mokopane corridor are being integrated into hydrogen and platinum-group-metal value chains. Recent feasibility studies and national green hydrogen planning have made the region increasingly attractive to investors. The local development vision is to integrate renewable energy generation with mining operations and downstream green hydrogen and green ammonia applications. This approach aims to link industrial decarbonisation and new export opportunities with local job creation and investment. Waterberg is also seeking to strengthen collaboration with universities by fostering local and international research partnerships to spur pilot projects and nurture green start-ups across emerging value chains.
Mauritania has become a high-potential green hydrogen country due to its exceptional wind and solar resources and favourable export position toward Europe. Several large-scale, export-oriented hydrogen and ammonia projects have been announced or are under development. While the national strategy prioritises export-driven green hydrogen production, it also emphasises renewable energy use to support domestic power grids and industry. However, as national projects advance, municipalities within Nouakchott—particularly Sebkha and Ksar, – continue to face high electricity costs, pollution, limited infrastructure, and the absence of clear municipal hydrogen strategies. These communes are not seeking merely to host hydrogen developments, they aim to participate meaningfully in shaping equitable, community-centered value creation within Mauritania’s emerging green hydrogen economy. The City of Nouakchott through its private sector and international partnerships, now seeks to position itself as an active player in his transition with a focus on modernizing urban services , strengthening governance, and building local private-sector capacity ultimately becoming a regional hub for green urban development, logistics, and industrial enterprises linked to the green hydrogen value chain.
The participating German cities also shared key insights and updates on their latest initiatives. Karlsruhe highlighted its hydrogen hub around the Rhine ports (H2iPortKA) and its strong research ecosystem in collaboration with the Karlsruhe Institute of Technology and the Fraunhofer Institutes. Particularly noteworthy is the dynamic start-up and spin-off environment, which demonstrates how the green transition can generate new jobs and investment for an entire region.
Heilbronn, well known as a centre for technology and hydrogen innovation within Germany’s automotive and engineering clusters, aims to use green hydrogen to diversify its industrial base, upgrade workforce skills, and anchor research-driven companies in the region. Heilbronn University and nearby Fraunhofer initiatives are expanding applied research and innovation centers—including those focused on hydrogen technologies—leveraging strong industry links for piloting and skills development.
The workshop underscored the vast opportunities emerging around green hydrogen production across regions endowed with abundant renewable energy resources.. However, cities and regions hosting these new green industries are often overlooked in national strategies that prioritize high-profile investments and export ambitions. Many localities remain uncertain of how they and their populations can directly participate in these developments. Significant technological and institutional gaps persist, and synergies between international high-tech initiatives and local realities are not automatic. As a result, municipalities are increasingly seeking models, international experiences, expertise, and partnerships to strengthen their capacity and create a level playing field:- one that enables prosperous, innovative and equitable local economies in which nations, investors, and communities all benefit alongside advancing technologies

Green Hydrogen for Local Development
Naivasha, Kenya | 14–17 April 2025 – Green hydrogen is gaining global attention as a key energy carrier for the future. While much of the discussion centres on export potential, green hydrogen production also holds significant potential for local development—boosting municipal infrastructure and stimulating local economies, especially in Africa, where the continent’s high potential for solar and wind energy brings African cities in a unique position to become innovation hubs and key drivers in the global energy transition.
To foster exchange of experiences and best practices between African and German cities, Connective Cities organised the workshop “Exploring the Potential of Green Transition for Local Economic Development”, bringing together over 30 municipal professionals from both regions.
The role of cities in promoting green hydrogen
The workshop, which focused on the role of cities in advancing green hydrogen as a lever for sustainable economic growth, facilitated a peer-to-peer learning space for municipal actors to exchange experiences, address challenges, and explore pathways for green hydrogen adoption at the local level.
Municipal strategies and shared challenges
A central focus of the exchange was how technological innovation can align with local development needs. Discussions ranged from decentralised hydrogen production systems and seawater electrolysis to the use of organic waste as a renewable source. Especially for coastal or water-scarce cities in Africa, such technologies were seen as promising solutions to local resource constraints.
However, participants agreed that technology alone is not enough. Effective local hydrogen strategies require strategic urban planning, transparent land management, and strong community engagement. Several municipalities shared examples of inclusive planning processes, involving traditional authorities and local universities in shaping future-oriented land use plans and infrastructure projects.
Participants from countries including Namibia, South Africa, Mauritania, Kenya, and Germany presented concrete initiatives demonstrating how hydrogen projects can generate local value. The example of Arandis (Namibia) illustrated how targeted investment and strategic partnerships are enabling the town to position itself as a production hub for green hydrogen. In contrast, the Heilbronn region (Germany) focuses on the application and industrial use of hydrogen, building a regional value chain by attracting user industries and technology providers.
Furthermore, Karlsruhe (Germany) showcased a successful ecosystem for start-ups working in hydrogen technologies, supported by research institutions and public-private partnerships. Across all cases, one message became clear: municipal masterplans and coordinated strategic planning are essential for cities to fully benefit from the emerging hydrogen economy.
The discussions underscored the growing role of cities not only as implementers of national energy goals, but as active shapers of the green transition. The workshop aimed to empower municipalities to position themselves as testing grounds, innovation platforms, and investment destinations within a future green hydrogen economy.
Outlook and next steps
The workshop concluded with a strong call for municipal leadership in developing local hydrogen strategies that reflect both environmental ambitions and socio-economic priorities. Participants identified three key areas for action:
- Local value creation: Prioritising domestic use of hydrogen for local industries – such as fertiliser or building materials – rather than relying solely on export models.
- Education and skills development: Aligning vocational training and higher education programmes with future labour market needs in the hydrogen sector.
- Partnerships and knowledge exchange: Strengthening peer-to-peer learning and cooperation among municipalities through platforms such as Connective Cities.
Participants also highlighted that green hydrogen offers more than energy solutions – it can help create future-oriented jobs, stimulate innovation, and improve urban living conditions. By linking clean energy production with economic development, municipalities can promote both resilience and inclusivity.
The workshop in Naivasha confirmed that green hydrogen can become a key pillar of sustainable urban development – provided that cities take a proactive role. Where political commitment, technical capacity and community participation come together, green hydrogen has the potential to drive long-term prosperity and shared growth.
“Whether peer learning sessions, inspiring impulses or practical insights into hydrogen strategies, sustainable mobility and local project development – the variety of formats impressively demonstrated how much potential there is in partnership-based cooperation.“

Lörrach plans Germany’s first timber-built commercial area
In 2020 the town of Lörrach purchased the 8.5-hectare Lauffenmühle site which had formerly been home to a textile factory. The purchase was made possible by urban development grants worth €9.1 million from Germany’s federal government and the state of Baden-Württemberg.
Following discussions with the Potsdam Institute for Climate Impact Research, the idea arose of creating a timber-built climate-neutral commercial area on the site.
The historic factory buildings on the site and their stone facades are not protected monuments, but the project still plans to repair and retain their basic structure in order to utilise them for new commercial purposes. By doing this, the project hopes that people will be able to identify with the project, particularly in the surrounding areas.
The project can serve as a model for other municipalities in Germany and around the world, providing that entire commercial areas can be built of timber.

Banepa preserves traditional construction methods using bio-based materials
The historic town centre of Banepa in Nepal extends along a road for a distance of around 1.2 kilometres. Many of the houses have been in poor condition, making the town less attractive.
This good practice describes how the town of Banepa is restoring its historic centre and a retirement home using traditional construction methods. Bio-based building materials such as wood, bamboo, brick and clay are significantly more sustainable and earthquake-resistant than cement or concrete.
In order to allay the concerns of the local population, the municipality is first refurbishing one building to provide an example of the methods that will be applied to the others. It is working together with the Nepalese RP Foundation, which has over 25 years of experience in the renovation of historical buildings.
This good practice was presented at the Connective Cities dialogue event on climate-friendly construction with organic and recycled materials in Potsdam.
