Green Hydrogen and Emerging Cleantech Opportunities

While renewable electricity has made significant gains in power generation and transport, some of the world’s largest industrial sectors remain heavily dependent on fossil fuels. Industries such as steel, cement, chemicals, aviation and shipping require either extremely high temperatures or fuels with a much higher energy density than current battery technologies can provide. Green hydrogen has become a focal point in efforts to address this challenge. Produced by using renewable electricity to split water into hydrogen and oxygen, it offers a potential pathway for reducing emissions in sectors where direct electrification remains difficult.

For much of the past decade, green hydrogen struggled to gain commercial traction. Production costs were high, supporting infrastructure was limited and demand remained uncertain. Falling renewable energy costs, tighter emissions regulations and growing pressure on companies to decarbonise supply chains have altered that equation. Governments and private investors are now committing substantial capital to hydrogen projects, while manufacturers are evaluating how hydrogen could fit into long-term production strategies.

Beyond Hydrogen Production

This activity extends well beyond the production of hydrogen itself. Building an economy around the commodity requires new equipment, infrastructure and digital systems, opening opportunities across a broad range of cleantech sectors.

One area receiving a fair share of investment is electrolyser technology. Electrolysers are central to hydrogen production, and manufacturers are competing to improve efficiency while reducing dependence on costly materials such as platinum and iridium. Lower-cost, more durable systems will be critical if green hydrogen is to compete with conventional production methods.

The infrastructure challenge presents another set of opportunities. Hydrogen requires specialised storage, transport and handling systems, creating demand for engineering firms, equipment manufacturers and logistics providers. Ports, pipelines, storage facilities and export terminals are expected to account for a substantial share of investment as projects move from pilot scale to commercial deployment. Digital technologies are also becoming part of the hydrogen value chain. As buyers seek assurance that hydrogen has been produced using renewable energy, software platforms are being developed to track production data, monitor emissions and support certification requirements. These systems are likely to play an increasingly important role as international markets establish standards for low-carbon fuels.

The build-out of hydrogen capacity is also generating opportunities for companies operating in water infrastructure. Many proposed projects are located in regions with abundant solar and wind resources, where water availability can be a constraint. As a result, desalination and industrial water treatment are becoming important components of project development rather than standalone environmental considerations.

Industrial Investment Patterns

The implications extend beyond hydrogen production itself. Heavy industry has traditionally been built around access to raw materials, transport networks and fossil fuel supplies. Hydrogen is introducing a different calculation. In regions where renewable power can be generated at a lower cost, companies are exploring whether industries such as fertiliser production, steelmaking and chemical processing should be located closer to the energy source rather than the end market.

The idea is simple: instead of moving hydrogen to industrial centres, move some industrial activity closer to where hydrogen can be produced most competitively. If that approach gains traction, it could influence where new factories are built and where future industrial investment is directed.

There are still significant obstacles. Green hydrogen remains more costly than conventional fuels in most markets, while the pipelines, storage facilities and export infrastructure needed to support a large-scale industry are still limited. Cost reductions, larger production volumes and continued infrastructure buildout will play a major role in determining how quickly hydrogen moves into mainstream industrial use.

The Economics of Scale

Whether green hydrogen fulfils its promise as a large-scale industrial fuel remains dependent on cost, infrastructure and market demand. What is already clear, however, is that the sector is driving investment across a wide range of cleantech industries. From advanced manufacturing and industrial software to water treatment and logistics infrastructure, the technologies supporting hydrogen are becoming a market in their own right.
