                    [post_content] => As the world races to decarbonize its energy systems, the choice between transmitting green energy as electrons through high-voltage direct current (HVDC) lines or as molecules via hydrogen pipelines emerges as a critical decision. This paper considers this pivotal choice and compares the techno-economic characteristics of these two transmission technologies.

Hydrogen pipelines offer the advantage of transporting larger energy volumes, but existing projects are dwarfed by the vast networks of HVDC transmission lines. Advocates for hydrogen pipelines see potential in expanding these networks, capitalizing on hydrogen’s physical similarities to natural gas and the potential for cost savings. However, hydrogen’s unique characteristics, such as its small molecular size and compression requirements, present construction challenges. On the other hand, HVDC lines, while less voluminous, excel in efficiently transmitting green electrons over long distances. They already form an extensive global network, and their efficiency makes them suitable for various applications. Yet, intermittent renewable energy sources pose challenges for both hydrogen and electricity systems, necessitating solutions like storage and blending.

Considering these technologies as standalone competitors belies their complementary nature. In the emerging energy landscape, they will be integral components of a complex system. Decisions on which technology to prioritize depend on factors such as existing infrastructure, adaptability, risk assessment, and social acceptance. Furthermore, while both HVDC lines and hydrogen pipelines are expected to proliferate, other factors such as market maturity of the relevant energy vector, government policies, and regulatory frameworks around grid development and utilization are also expected to play a crucial role. Energy transition is a multifaceted challenge, and accommodating both green molecules and electrons in our energy infrastructure may be the key to a sustainable future. This paper’s insights underline the importance of adopting a holistic perspective and recognising the unique strengths of each technology in shaping a resilient and sustainable energy ecosystem.

                    [post_content] => If a hydrogen economy is to become a reality, along with efficient and decarbonized production and
adequate transportation infrastructure, deployment of suitable hydrogen storage facilities will be crucial.
This is because, due to various technical and economic reasons, there is a serious possibility of an
imbalance between hydrogen supply and demand. Hydrogen storage could also be pivotal in promoting
renewable energy sources and facilitating the decarbonization process by providing long duration
storage options, which other forms of energy storage, such as batteries with capacity limitations or
pumped hydro with geographical limitations, cannot meet. However, hydrogen is not the easiest
substance to store and handle. Under ambient conditions, the extremely low volumetric energy density
of hydrogen does not allow for its efficient and economic storage, which means it needs to be
compressed, liquefied, or converted into other substances that are easier to handle and store. Currently,
there are different hydrogen storage solutions at varying levels of technology, market, and commercial
readiness, with different applications depending on the circumstances. This paper evaluates the relative
merits and techno-economic features of major types of hydrogen storage options: (i) pure hydrogen
storage, (ii) synthetic hydrocarbons, (iii) chemical hydrides, (iv) liquid organic hydrogen carriers, (v)
metal hydrides, and (vi) porous materials. The paper also discusses the main barriers to investment in
hydrogen storage and highlights key features of a viable business model, in particular the policy and
regulatory framework needed to address the primary risks to which potential hydrogen storage investors
are exposed.

As a manufactured fuel, hydrogen can be produced in a decentralized way in most countries around the world. This means, even in a net zero economy, the global trade of hydrogen could look quite different to the current international trade in fossil fuels, including natural gas. With further declines in the costs of renewable electricity and electrolyzers, regions which have lower cost renewable electricity may develop an economic advantage in the production of low-cost hydrogen, but for hydrogen to become a globally traded commodity, the cost of imports needs to be lower than the cost of domestic production. Unlike oil or natural gas, transporting hydrogen over long distances is not an easy task. Hydrogen liquefaction is an extremely energy-intensive process, while maintaining the low temperature required for long-distance transportation and storage purposes results in additional energy losses and accompanying costs. The upside is that hydrogen can be converted into multiple carriers that have a higher energy density and higher transport capacity and can potentially be cheaper to transport over long distances. Among the substances currently identified as potential hydrogen carriers suitable for marine shipping, liquid ammonia, the so-called ‘liquid organic hydrogen carriers’ in general (toluene-methylcyclohexane (MCH) in particular), and methanol have received the most attention in recent years. This paper compares the key techno-economic characteristics of these potential carriers with that of liquified hydrogen in order to develop a better understanding of the ways in which hydrogen could be transported overseas in an efficient manner. The paper also discusses other factors, beyond techno-economic features, that may affect the choice of optimum hydrogen carrier for long distance transport, as well as the global trade, of hydrogen.

The higher cost of green hydrogen in comparison to its competitors is the most important barrier to its increased use. Although the cost of renewable electricity is considered to be the key obstacle, challenges associated with electrolysers are another major issue that have important implications for the cost reduction of green hydrogen. This paper analyses the electrolysis process from technological, economic, and policy perspectives. It first provides a comparative analysis of the main existing electrolyser technologies and identifies key trade-offs in terms of cost, scarcity of materials used, technology readiness, and the ability to operate in a flexible mode (which enables them to be coupled with variable renewables generation). The paper then identifies the main cost drivers for each of the most promising technologies and analyses the opportunities for cost reduction. It also draws upon the experience of solar and wind power generation technologies with respect to gradual cost reduction and evaluates development paths that each of the main electrolyser technology types could take in the future. Finally, the paper elaborates on the policy mechanisms that could additionally foster cost reduction and the overall business development of electrolyser technologies.

This paper analyses whether ammonia can be viewed as an economically efficient and technologically suitable solution that can address the challenge of large-scale, long-duration, transportable energy storage in the decarbonized energy systems of the future. It compares all types of currently available energy storage techniques and shows that ammonia and hydrogen are the two most promising solutions that, apart from serving the objective of long-term storage in a low-carbon economy, could also be generated through a carbon-free process. The paper argues that ammonia, as an energy vector of hydrogen, is preferable to pure hydrogen from economic, environmental, and technological perspectives. It then analyses the available ammonia generation techniques, identifying conditions under which zero-carbon ammonia makes sense economically, and briefly highlights policy prerequisites for such production to be attractive for investors. Given the current state of the industry, large-scale deployment of green ammonia is unlikely to happen without policy supports such as adequate carbon taxes and/or alternative incentives. In the absence of such policies, green ammonia is only likely to make small-scale advances in the energy system, in areas with extremely low-cost renewable energy production or a significant surplus of generated energy.

This paper considers this pivotal choice and compares the techno-economic characteristics of these two transmission technologies. Hydrogen pipelines offer the advantage of transporting larger energy volumes, but existing projects are dwarfed by the vast networks of HVDC transmission lines. Advocates for hydrogen pipelines see potential in expanding these networks, capitalizing on hydrogen’s physical similarities to natural gas and the potential for cost savings. However, hydrogen’s unique characteristics, such as its small molecular size and compression requirements, present construction challenges. On the other hand, HVDC lines, while less voluminous, excel in efficiently transmitting green electrons over long distances. They already form an extensive global network, and their efficiency makes them suitable for various applications. Yet, intermittent renewable energy sources pose challenges for both hydrogen and electricity systems, necessitating solutions like storage and blending. Considering these technologies as standalone competitors belies their complementary nature. In the emerging energy landscape, they will be integral components of a complex system. Decisions on which technology to prioritize depend on factors such as existing infrastructure, adaptability, risk assessment, and social acceptance. Furthermore, while both HVDC lines and hydrogen pipelines are expected to proliferate, other factors such as market maturity of the relevant energy vector, government policies, and regulatory frameworks around grid development and utilization are also expected to play a crucial role. Energy transition is a multifaceted challenge, and accommodating both green molecules and electrons in our energy infrastructure may be the key to a sustainable future. This paper’s insights underline the importance of adopting a holistic perspective and recognising the unique strengths of each technology in shaping a resilient and sustainable energy ecosystem.
