Abstract:
Hydrogen has become one of the most debated topics in the energy industry. As an energy vector,[1] hydrogen has been touted as a possible path to decarbonize energy sectors that are considered difficult to electrify, such as heavy-duty transport. While hydrogen expansion faces challenges associated with introducing it into new sectors and decreasing the cost of green (or low-emission) hydrogen, major economies such as China, the EU, and the United States have been looking to integrate its use into their decarbonization strategies.[2] Demand for hydrogen could more than quintuple in a global net-zero-carbon-emissions scenario.[3] Given that hydrogen’s role is expected to increase significantly over the coming decade and expand into new sections of the energy system, it is essential to have more clarity on its current and future demand profile. The energy community is used to relying on statistics for more traditional fuels such as oil or natural gas; they enable analysts and investors to follow market developments, identify trends, and anticipate investment needs and opportunities. For policy makers, they can help to measure progress toward decarbonization objectives or against targets set within their hydrogen strategies as well as help them compare their activity with other countries’ developments. Understanding demand, production, and trade through data transparency is also a key element in energy security.

Abstract:
Hydrogen is seen as a means to decarbonise sectors with greenhouse gas emissions that are hard to reduce, as a medium for energy storage, and as a fallback in case halted fossil-fuel imports lead to energy shortages. Hydrogen is likely to play at least some role in the European Union’s achievement by 2050 of a net-zero greenhouse gas emissions target. However, production of hydrogen in the EU is currently emissions intensive. Hydrogen supply could be decarbonised if produced via electrolysis based on electricity from renewable sources, or produced from natural gas with carbon, capture, and storage. The theoretical production potential of low-carbon hydrogen is virtually unlimited and production volumes will thus depend only on demand and supply cost. Estimates of final hydrogen demand in 2050 range from levels similar to today’s in a low-demand scenario, to ten times today’s level in a high-demand scenario. Hydrogen is used as either a chemical feedstock or an energy source. A base level of 2050 demand can be derived from looking at sectors that already consume hydrogen and others that are likely to adopt hydrogen. The use of hydrogen in many sectors has been demonstrated. Whether use will increase depends on the complex interplay between competing energy supplies, public policy, technological and systems innovation, and consumer preferences. Policymakers must address the need to displace carbon-intensive hydrogen with low-carbon hydrogen, and incentivise the uptake of hydrogen as a means to decarbonise sectors with hard-to-reduce emissions. Certain key principles can be followed without regret: driving down supply costs of low-carbon hydrogen production; accelerating initial deployment with public support to test the economic viability and enable learning; and continued strengthening of climate policies such as the EU emissions trading system to stimulate the growth of hydrogen-based solutions in the areas for which hydrogen is most suitable.

Abstract:
The transition to a low-carbon energy system will likely shake up the geopolitical status quo that has governed global energy systems for over a century. Policymakers need to rethink the role their country could play in a new energy world. Renewables are widely perceived as an opportunity to shatter the hegemony of fossil fuel-rich states and democratize the energy landscape. Virtually all countries have access to some renewable energy resources (especially solar and wind power) and could thus substitute foreign supply with local resources. Our research shows, however, that the role countries are likely to assume in decarbonized energy systems will be based not only on their resource endowment but also on their policy choices. Renewable hydrogen is enjoying growing political and commercial momentum as a versatile and sustainable energy carrier with the potential to play a key role in the global transition to a low-carbon economy; and it is often described as the ‘missing link’ in global decarbonization—especially for energy intensive sectors where emissions are hard to abate and electrification is not the preferred solution, such as steel production, high-temperature industrial heat, shipping, aviation, and heat for buildings. But making renewable hydrogen a significant part of the world’s future energy mix will require defining new and innovative national and international policies while developing appropriate market structures aimed at spurring innovation along value chains; scaling technologies while significantly reducing costs; and deploying enabling infrastructure at scale. Success is possible, but this transformational effort will require close coordination between policy, technology, capital, and society to avoid falling into the traps and inefficiencies of the past. Renewable hydrogen can be used for both mobility and stationary applications. As a sustainable mobility energy carrier, it can power fuel-cell electric vehicles or be the base for synthetic fuels. In stationary applications, it can be used to store renewable energy, both at utility scale or off-grid, providing backup to intermittent renewable energy sources and serving as a carbon-free heating source. From a geopolitical perspective, whether future renewable hydrogen energy systems will be as concentrated as today’s oil and gas supply or decentralized like renewables is strongly related to future market structures, technology, and enabling infrastructure availability.

24. China: The Renewable Hydrogen Superpower?

Abstract:
President Xi Jinping’s pledge during the 2020 United Nations General Assembly, that China would reach peak carbon dioxide emissions by 2030 and achieve carbon neutrality before 2060, is a significant step in the fight against climate change. Since China is the world’s top contributor of greenhouse gases, there is no doubt that Beijing needs to be front and center of any effort to curb global emissions. In 2019, China accounted for almost 30 percent of global emissions, about twice as much as the second largest emitter, the United States.1 But while U.S. emissions have been on an overall decline since 2007,2 China’s have increased, raising concerns over whether Beijing can actually deliver on its targets. This reality should not distract from the fact that China is also the world’s top developer of renewables and other clean energy technologies. For example, China was the world’s largest installer of photovoltaics (PV) by 2013 and, in less than two years, also became the global leader in solar module manufacturing. At the same time, China leveraged its industrial might and economies of scale to drive down modules’ costs—which, by the end of 2018, were 90 percent lower than only ten years before. In this context, renewable hydrogen could significantly accelerate China’s transition to a low-carbon economy, increasing the likelihood of meeting its carbon neutrality goal. Renewable hydrogen offers significant advantages for China. It can help Beijing meet its climate and pollution goals—at a time when coal continues to dominate—while avoiding increased reliance on imported fuels. As a readily dispatchable means of storing energy, hydrogen can help to address intermittency and curtailment issues as renewable energy increases its share of China’s energy mix. As a sustainable mobility energy carrier, it can power fuel-cell electric vehicles or be the base for synthetic fuels. Finally, renewable hydrogen can open new avenues for developing clean technology manufactured goods for both internal and export markets. Today, most of China’s hydrogen is produced from coal via 1,000 gasifiers, accounting for 5% of the country’s total coal consumption. Hydrogen costs vary significantly as a function of production technology and prices of fossil fuels and electricity. Production from coal remains the lowest cost option: about 30 percent cheaper than hydrogen from natural gas. Therefore, reducing the carbon footprint of coal-based hydrogen will be critical in a low-carbon economy. In the medium term, coal-based hydrogen with carbon capture, utilization and storage will likely remain China’s lowest-cost clean hydrogen production pathway. Hence, the underlying question is whether Beijing will prioritize cost considerations or put its full industrial might behind the development and deployment of renewable hydrogen. In March 2019, the Chinese government took a significant step forward by announcing measures to promote the construction of hydrogen facilities for new energy vehicles. Wan Gang, who is known as China’s “father of the electric car,” called for China to “look into establishing a hydrogen society” and “move further toward fuel cells.”3 Given that Gang made a similar call two decades ago on vehicle electrification, which played a key role in China’s current battery electric vehicles market dominance, close attention is warranted.

25. Sustainable Mobility: Renewable Hydrogen in the Transport Sector

Abstract:
The transportation sector is the second-largest source of CO2 emissions, after electricity and heat generation, accounting for about 25 percent of global emissions.1 However, it is also one of the most challenging to decarbonize due to its distributed nature and the advantages of fossil fuels in terms of high energy densities, ease of transportation, and storage. Moreover, the degree of difficulty in decarbonizing varies significantly across the sector, making the challenge even more daunting. So far, emissions reduction strategies have focused on improving vehicle and system-wide efficiencies, mode switching, and electrification. The latter is proving relatively easy for smaller vehicles that travel shorter distances and carry lighter loads. However, sector-wide decarbonization pathways will require a transition to low-carbon fuels and the deployment of enabling infrastructure to support innovation at scale. Renewable hydrogen holds promise in sustainable mobility applications, whether by powering fuel-cell electric vehicles (FCEVs) like cars, trucks, and trains or as a feedstock for synthetic fuels for ships and airplanes. Fuel cells convert hydrogen-rich fuels into electricity through a chemical reaction. FCEVs use a fuel cell, rather than a battery, to power electric motors, and operate near-silently and produce no tailpipe emissions. Hydrogen-powered vehicles offer key advantages, including shorter refueling times, longer ranges, and a lower material footprint compared to lithium battery-powered alternatives. However, high costs of ownership and a lack of enabling infrastructure are key challenges that must be addressed through policy support, technological innovation, and financial investment. Hydrogen can complement existing efforts to electrify road and rail transportation and provide a scalable option for decarbonizing shipping and aviation. Figure 1 summarizes the mobility segments for which battery electric vehicles (BEVs), FCEVs, and vehicles running on bio- or hydrogen-based synthetic fuels are most applicable.

Abstract:
Clean hydrogen is experiencing unprecedented momentum as confidence in its ability to accelerate decarbonization efforts across multiple sectors is rising. New projects are announced almost every week. For example, an international developer, Intercontinental Energy, plans to build a plant in Oman that will produce almost 2 million tons of clean hydrogen and 10 million tons of clean ammonia.1 Dozens of other large-scale projects and several hundred smaller ones are already in the planning stage. Similarly, on the demand side, hydrogen is gaining support from customers. Prominent off-takers such as oil majors like Shell and bp, steelmakers like ThyssenKrupp, and world-leading ammonia producers like Yara are working on making a clean hydrogen economy a reality. Despite the optimism surrounding clean hydrogen, key uncertainties remain. One of hydrogen’s attractions is that it can provide carbon-free energy in multiple sectors—transport, heating, industry, and electricity generation. But this advantage also creates uncertainties. The infrastructure needed in an economy in which hydrogen is primarily used as a transport fuel is very different from one in which its primary value is as a heating fuel. Today no major hydrogen pipeline networks exist,2 and no liquified hydrogen ships are in commercial operation. There is a true chicken and egg problem. If there is no infrastructure to move hydrogen, will investments in supply and demand happen at the pace needed to meet national decarbonization targets? This challenge raises an even more pressing question: what should be the respective roles of the public and private sectors in deploying enabling infrastructure at scale?

Abstract:
Hydrogen is the most promising vector for harnessing North Africa’s largely untapped renewable energy potential. Low-carbon hydrogen produced in North Africa can play an important role in enabling the European Union and Italy to reach their increasingly ambitious decarbonisation targets as a complement to electrification and locally produced renewables. It is estimated that the EU could achieve cost savings by producing at least part of its future renewable energy needs in neighbouring high-yield regions. Italy is set to play a particularly important function as both a gateway and a catalyst for North African hydrogen exports. In turn, North Africa stands to benefit from hydrogen both as a source of revenues and as an instrument of diversification, industrialisation and local economic development. This would in turn improve social resilience, increase political stability, reduce the risk of radicalisation and limit migration flows. Italy has a particularly strong strategic interest in all of these areas, given its geographic location in the Central Mediterranean and marked exposure to social, political and security developments in North Africa. North African hydrogen could also create profitable business opportunities for several Italian companies. In sum, hydrogen can contribute to fighting climate change while preserving positive trade interdependence across the Mediterranean. Strong coordination between the private sector and policy-makers is going to be key to abate costs along the hydrogen value chain and launch successful international hydrogen trade schemes.

Abstract:
A rainbow of colors currently dominates almost every conversation on the transition to a low-carbon economy: green, grey, blue, turquoise, pink, yellow[1] - an ever-increasing palette to describe the same colorless, odorless, and highly combustible molecule, hydrogen. The only difference is the chemical process used to produce it. The colors of hydrogen are crucial for the energy transition because each production pathway generates different amounts of greenhouse gas emissions. For example, while grey hydrogen, produced from fossil fuels, yields up to 20 tons of carbon dioxide per ton of hydrogen, green hydrogen, produced from renewable energy sources like solar and wind, yields no emissions. Furthermore, although these colors all refer to the same molecule, production costs differ: green hydrogen remains substantially more costly today. With aggressive development and deployment of electrolyzers and other hydrogen technologies at scale, green hydrogen could become cost-competitive with blue hydrogen, produced from natural gas with carbon capture, by 2030 in many countries.[2] Overall, the rate at which green hydrogen costs decrease will also depend on government policies and incentives, such as carbon pricing and tax credits. Therein lies a critical challenge for the successful transition to a low-carbon economy. As energy systems increasingly evolve from centralized to decentralized, from “grey” to “green,” stakeholders will need to efficiently account for and track emissions and green molecules in a transparent, secure, and standardized way, and must be able to do so along value chains from production to consumption.

Abstract:
European countries are at a crossroads on their path to carbon neutrality. Today, they are at the forefront of the global clean hydrogen race but going forward they would be better served by collaborating instead of working alone. Overall, the European Union (EU) is highly competitive in clean technologies manufacturing and thus well-positioned to benefit from the emergence of global hydrogen markets. But a narrow focus on short-term cost considerations could drive member states to implement national roadmaps with little or no coordination among themselves and hence little or no chance of competing globally. As a bloc, the EU has pledged to reach carbon neutrality by 2050. Clean hydrogen is a cornerstone of this transformational effort; accordingly, in July 2020, the EU adopted its hydrogen strategy with the ambition of deploying open and competitive clean hydrogen markets for all energy sectors and segments by 2050.1 Success hinges around implementing a cohesive long-term strategy to address a fundamental ques- tion and its associated challenges: where could the EU source competitive and secure renewable hydrogen supplies? As our previous research shows, all countries have access to renewable resources (such as solar or wind), to different degrees, and could produce some renewable hydrogen locally. However, while resource-rich countries, such as Spain, could evolve into regional exporters, no EU member state has the potential to become a global export champion. At the same time, North African countries, such as Morocco, are well-situated to act as key suppliers to the EU. Furthermore, imports from resource-rich regions like North America could help to address security of supply concerns.2 Today, EU hydrogen demand stands at 7.8 million tons per year (Mt/yr), equivalent to about 10% of global demand. Germany and the Netherlands are the largest consumers, accounting for over a third of EU demand, followed by Poland, Spain, Italy, Belgium, and France, which consume about 0.5 Mt/yr each.3 According to available projections, as hydrogen use grows across all economic sectors, EU hydrogen demand could reach 76 Mt/yr by 2050. But while the EU strategy sets clear targets on electrolyzer deployment by 2030, it provides very few details on how the bloc could meet demand—and at what cost—by 2050.

Abstract:
Hydrogen is positioned as a strong candidate for fulfilling the carbon-neutrality objective set out in the European Green Deal, provided that it is able to compete on a level-playing field with other technologies favoring sector coupling. Pushing the envisioned hydrogen economy past its tipping point necessitates a conducive EU regulation, repurposing of existing large-scale EU networks, along with additional investments, as well as strategic partnerships with the EU’s third-country suppliers. This paper aims to outline the role of hydrogen as a component of the decarbonization of the European natural gas sector, in the context of an integrated energy system.
