About Green Hydrogen

Green hydrogen is emerging as a critical solution for addressing climate change, but to realize its full potential, policymakers, industry leaders, and investors must fund essential infrastructure and encourage research and development. Many developing countries view industrialization as a benchmark for economic growth and success. This includes large infrastructure investments in heavy industries like steel and cement, fertilizer and other chemical production, shipping, and aviation fuels.

Policies and regulations, such as the “Green Deal” in Europe or the Inflation Reduction Act in the United States, create policy and financial incentives to decarbonize these large and polluting industries. For advanced economies, this involves retrofitting existing industries to low-carbon energy sources while developing new green industrial sectors. The focus lies in funding a “safe switch” that does not jeopardize the already achieved industrialization standard.

Scaling up the share of renewables quickly can be achieved through solar and wind capacity to produce green hydrogen and its derivatives for use in these industrial sectors. Green hydrogen can be produced through the electrolysis of water with close to zero greenhouse gas emissions. This offers a promising solution for decarbonizing “hard-to-abate” industries and establishing green energy at scale. However, green hydrogen is currently expensive at $5 per kilogram, which is five times more expensive than fossil hydrogen (grey or black hydrogen).

For developing countries, the challenge involves de-risking investments in new energy technology and infrastructure to expand affordable energy access, ensure energy security, and attract investors to establish new industries. This, in turn, creates jobs, generates revenue, and increases tax income. This requires sound knowledge-based policy and regulation, coupled with market-making subsidy regimes. This is particularly important for the large investments required to scale green hydrogen. Besides financial risks, there are other challenges for green hydrogen: limited supply chains, safety concerns due to hydrogen’s high explosiveness, rapidly increasing renewables capacity, a shortage of skilled personnel to operate green hydrogen plants, and ramping up the manufacture of electrolyzers.

Although green hydrogen currently represents a small portion of the global energy mix, its use has a significant impact on emissions. For countries without fossil resources, green hydrogen also offers a path to higher energy security with lower carbon emissions.

Countries are beginning to define green hydrogen, specifying threshold carbon emissions and production sources necessary to classify hydrogen as “green.” This approach helps establish standards and regulations and develop policies for green hydrogen and electrolyzer manufacturing. For instance, India is actively promoting green hydrogen investments in targeted hubs, offering tax incentives and financing access to accelerate hydrogen merchant markets and the necessary transport infrastructure.

Green hydrogen investments can be grouped into three pathways: as a commodity with large-scale renewable energy production, to reduce carbon emissions in challenging areas, and at a distributed level for social and environmental impacts.

1. Green Hydrogen as a Commodity with Large-Scale Renewable Energy Production

This includes hydrogen valleys/hubs and ports infrastructure. However, the price differential between fossil and green hydrogen is a challenge for these investments. Investments in green hydrogen as a commodity require significant capital and policy support to develop the necessary infrastructure, such as large-scale electrolyzers and hydrogen storage facilities. Strategic locations, like ports and industrial hubs, are ideal for setting up these large-scale projects due to their existing infrastructure and high energy demands.

2. Green Hydrogen to Reduce Carbon Emissions in Challenging Areas

This pathway targets hard-to-abate industries like steel, cement, fertilizer production, aviation fuel, and marine transport. Projects in this space often make financial sense due to efficiency gains and potential carbon credit revenues. These industries are some of the most significant contributors to global carbon emissions, and transitioning to green hydrogen can drastically reduce their environmental impact. Investment in this area includes retrofitting existing industrial processes and developing new technologies that utilize green hydrogen.

3. Green Hydrogen at a Distributed Level

This includes green hydrogen production from agricultural and municipal waste and the related transport and filling infrastructure. Distributed projects that support the supply chain for green hydrogen have a much higher development dividend for social and environmental impacts, such as local jobs, reduced transportation emissions, and opportunities for digitization to change existing supply chains. Distributed green hydrogen projects are less sensitive to cost variations and can provide significant benefits to local communities, including energy independence and reduced pollution.

While distributed green hydrogen production is less sensitive to cost variations, larger-scale projects are profoundly impacted by cost. The hard-to-abate sectors require a thriving green hydrogen industry to fuel decarbonization. Providing rational subsidies to kick-start the green hydrogen economy requires understanding why fossil hydrogen is currently so much cheaper than green hydrogen. The answer lies in the massive subsidies that fossil fuels receive and the fact that their price does not reflect the damage caused by carbon emissions.

The real cost of carbon emissions ranges from $50 to $200 per ton of CO2, and there is no global price on carbon emissions, only corporate shadow pricing or tariff adjustments in some countries. Fossil hydrogen can be five to 20 times more polluting than green hydrogen, depending on the technology used. Green hydrogen’s lowest emission rate is 1 kilogram of CO2 for every 1 kilogram of hydrogen.

The price difference between green and fossil hydrogen does not include the real carbon impacts, which can range from five cents to five dollars per kilogram of hydrogen, depending on the type.

This market distortion slows the adoption of green hydrogen. However, the scaling up of green hydrogen production could lead to significant cost reductions, similar to the massive price reductions seen in the solar industry deployment. A competitive unadjusted price of $1.25 per kilogram is a possibility in the long term, but this requires substantial work and investment. Targeted subsidies for green hydrogen will be necessary until such cost reductions are achieved.

The transition to green hydrogen is not just an environmental imperative but a strategic investment in our collective future. It’s time for policymakers, industry leaders, and investors globally to support initiatives and policies that accelerate the adoption of green hydrogen, invest in the necessary infrastructure, and promote research and development in this field.

By focusing on the three pathways of expanding green hydrogen investment—commodity production, reducing emissions in hard-to-abate sectors, and distributed production— we can pave the way for a sustainable and secure energy future.

Additionally, they support irrigation for agriculture and contribute to local ecosystems by providing habitats for wildlife. Notable examples of impoundment dams include the Hoover Dam in the United States and the Three Gorges Dam in China. 

Three Gorges Dam in China, is renowned for being the world’s largest hydroelectric power station in terms of installed capacity. This dam plays a crucial role in creating a significant reservoir on the Yangtze River, leading to substantial electricity generation and effective flood control. 

The Hoover Dam in the USA is situated on the Colorado River. This dam plays a vital role in forming Lake Mead while supplying electricity to millions of people in the southwestern United States.

2. Diversion dams

Diversion dams are structures built across rivers or streams to divert a portion of the water flow into canals, ditches, or other conveyance systems for purposes such as irrigation, municipal water supply, or industrial use. Unlike impoundment dams, diversion dams typically do not create large reservoirs but rather guide the water into specific pathways to meet various needs.

These dams help in efficiently directing water to agricultural fields, urban areas, or industrial facilities, thereby managing water resources effectively without significantly altering the river’s overall flow.

6. La Grande-1 in Canada, which is part of the James Bay Project in Quebec and is a run-of-river power station that uses the natural flow of the La Grande River for generating electricity.

3. Pumped storage dams

Pumped storage dams are a specific type of hydroelectric power system that involves two water reservoirs at different elevations. During periods of low electricity demand, electricity is used to pump water from the lower reservoir to the upper reservoir.

When electricity demand is high, water is released from the upper reservoir to the lower one, passing through turbines to generate electricity. This process allows the system to store energy and release it as needed, making it a highly effective method for balancing the supply and demand of electricity.

The following examples highlight the importance of pumped storage dams in providing reliable and flexible energy storage solutions to help manage the variability of electricity supply and demand.

1. Bath County Pumped Storage Station, Located in Virginia, USA, is one of the largest pumped storage facilities in the world with a capacity of 3,003 megawatts (MW).

2. Dinorwig Power Station, Situated in Wales, UK, has a capacity of about 1,728 MW and is known for its rapid response to electricity demand fluctuations.

3. Raccoon Mountain Pumped-Storage Plant, Located in Tennessee, USA, has a capacity of 1,652 MW and provides a significant energy storage capability for the region.

4. Goldisthal Pumped Storage Station in Germany. This plant has a capacity of 1,060 MW and is one of the largest in Europe.

5. Okutataragi Pumped Storage Power Station in Japan  has a capacity of 1,932 MW and plays a crucial role in stabilizing the country’s power grid.

Each variety of hydroelectric dam plays a pivotal role in the generation of renewable energy, making significant contributions to the global supply of electricity. Furthermore, they provide advantages such as energy storage and stability to the grid.

As with everything no energy source is perfect. Hydroelectric dams present several challenges, including significant environmental impacts such as disruption of local ecosystems and fish migration, and alteration of river flow patterns. They often require the displacement of communities, leading to social and economic disruptions.

Sedimentation can reduce reservoir capacity and affect downstream ecosystems, while the alteration of natural waterways can have broad ecological consequences. High construction and maintenance costs, along with the potential risk of catastrophic dam failures, add to the concerns.

Additionally, reservoirs can emit greenhouse gases like methane from decomposing organic matter. Water use conflicts may arise, particularly in arid regions, and indigenous communities often face displacement and disruption of their traditional lifestyles.

Moreover, the reliability of hydroelectric power is vulnerable to changes in water availability due to climate change. These challenges necessitate careful planning, management, and consideration of alternative energy sources to mitigate negative impacts.

Innovations in Hydroelectric Dams with countries as examples:

1. Fish-Friendly Turbines: Fish-friendly turbines are designed to minimize harm to fish and other aquatic organisms as they pass through hydroelectric plants. These turbines aim to reduce fish mortality and injury rates that are typically associated with conventional turbines. 

Fish-friendly turbines are an important development in sustainable hydropower, aiming to balance the need for renewable energy with the protection of aquatic ecosystems. Deer Island Hydroelectric Plant, Massachusetts, USA: This facility uses Alden turbines, designed to reduce fish mortality rates significantly. The turbines have a slower rotation speed and a shape that minimizes the risk of harming fish.

2. Small and Micro Hydropower: Small and micro hydropower systems generate electricity on a smaller scale compared to traditional large hydropower plants and are typically used in remote or rural areas.

Small hydropower systems produce between 1 MW and 10 MW, serving local grids, small communities, or industrial plants, while micro hydropower systems generate less than 100 kW, making them ideal for individual homes, small farms, or villages. Both types have lower environmental impacts, are easier to install and maintain, and are often more cost-effective for localized energy needs.

They provide a reliable, renewable energy source using the natural flow of water, making them a flexible and sustainable solution, especially in areas lacking grid access.

3. Pumped Storage Hydropower (PSH): Pumped storage hydropower is a type of hydroelectric power generation used to store and manage energy. It works by moving water between two reservoirs at different elevations. During periods of low electricity demand, excess energy from the grid is used to pump water from a lower reservoir to an upper reservoir.

When electricity demand is high, the stored water is released back to the lower reservoir through turbines, generating electricity. This system effectively acts as a large, rechargeable battery, storing energy in the form of gravitational potential energy and releasing it when needed. Pumped storage hydropower helps balance supply and demand, stabilizes the grid, and supports the integration of intermittent renewable energy sources like wind and solar power.
