Policy & Socio-Economics

This work investigates the impacts of variation management on the cost-optimal electricity system compositions in four regions with different pre-requisites for wind and solar generation. Five variation management strategies involving electric boilers batteries hydrogen storage low-cost biomass and demand-side management are integrated into a regional investment model that is designed to account for variability. The variation management strategies are considered one at a time as well as combined in four different system contexts. By investigating how the variation management strategies interact with each other as well as with different electricity generation technologies in a large number of cases this work support policy-makers in identifying variation management portfolios relevant to their context. It is found that electric boilers demand-side management and hydrogen storage increase the cost-optimal variable renewable electricity (VRE) investments if the VRE share is sufficiently large to reduce its marginal system value. However low-cost biomass and hydrogen storage are found to increase cost-optimal investments in wind power in systems with a low initial wind power share. In systems with low solar PV share variation management reduce the cost-optimal solar PV investments. In two of the regions investigated a combination of variation management strategies results in a stronger increase in VRE capacity than the sum of the single variation management efforts.

This paper looked at 39 hydrogen associations across Europe to understand which economic sectors support the hydrogen transition in Europe and why they do so. Several broad conclusions can be drawn from this paper. It is clear that the support for hydrogen is broad and from a very wide spectrum of economic actors that have clear interests in the success of the hydrogen transition. Motivations for support differ. Sales and market growth are important for companies pursuing professional scientific and technical activities as well as manufacturers of chemicals machinery electronic or electrical equipment and fabricated metals. The increasing cost of CO2 combines with regulatory and societal pressure to decarbonize and concerns from investors about the long-term profitability of sectors with high emissions. This makes hydrogen especially interesting for companies working in the energy transport steel and chemical industries. Another motivation is the ability to keep using existing fixed assets relevant for ports oil and gas companies and natural gas companies. More sector-specific concerns are a technological belief held by some motor vehicle manufacturers in the advantages of FCVs over BEVs for private mobility which is held more widely regarding heavy road transport. Security of supply and diversifying the current business portfolio come up specifically for natural gas companies. Broader concerns about having to shift into other energy technologies as a core business are reasons for interest from the oil and gas sector and ports.

Perhaps the most important lesson is that the hydrogen transition has already begun – but it needs continued policy support and political commitment. Carbon-intensive industries such as steel and chemicals are clearly interested and willing to invest billions but need policy support to avoid carbon leakage to high-carbon competitors before they commit. The gas grid is ready and many operators and utility companies are eager but they need clearance to experiment with blending in hydrogen. Hydrogen road vehicles still face many regulatory hurdles. There are several clusters that can serve as models and nuclei for the future European hydrogen economy in different parts of Europe. However these nuclei will need more public funding and regulatory support for them to grow.

The report “Hydrogen for Net Zero” presents an ambitious yet realistic deployment scenario until 2030 and 2050 to achieve Net Zero emissions considering the uses of hydrogen in industry power mobility and buildings. The scenario is described in terms of hydrogen demand supply infrastructure abatement potential and investments required and then compared with current momentum and investments in the industry to identify the investment gaps across value chains and geographies.

The report is based on the technoeconomic data of cost and performance of hydrogen technologies provided by Hydrogen Council members and McKinsey & Company as well as the Hydrogen Council investment tracker which covers all large-scale investments into hydrogen globally.

Deployment and investments in hydrogen have accelerated rapidly in response to government commitments to deep decarbonisation establishing hydrogen as a key component in the energy transition.

To help guide regulators decision-makers and investors the Hydrogen Council collaborated with McKinsey & Company to release the report ‘Hydrogen Insights 2021: A Perspective on Hydrogen Investment Deployment and Cost Competitiveness’. The report offers a comprehensive perspective on market deployment around the world investment momentum as well as implications on cost competitiveness of hydrogen solutions.

Hydrogen produced with renewable energy sources – or “green” hydrogen – has emerged as a key element to achieve net-zero emissions from heavy industry and transport. Along with net-zero commitments by growing numbers of governments green hydrogen has started gaining momentum based on low-cost renewable electricity ongoing technological improvements and the benefits of greater power-system flexibility.



Hydrogen-based fuels previously attracted interest mainly as an alternative to shore up oil supply. However green hydrogen as opposed to the “grey” (fossil-based) or “blue” (hybrid) varieties also help to boost renewables in the energy mix and decarbonise energy-intensive industries.



This report from the International Renewable Energy Agency (IRENA) outlines the main barriers that inhibiting green hydrogen uptake and the policies needed to address these. It also offers insights on how to kickstart the green hydrogen sector as a key enabler of the energy transition at the national or regional level.



Key pillars of green hydrogen policy making include:

• National hydrogen strategy. Each country needs to define its level of ambition for hydrogen outline the amount of support required and provide a reference on hydrogen development for private investment and finance.
• Setting policy priorities. Green hydrogen can support a wide range of end-uses. Policy makers should identify and focus on applications that provide the highest value.
• Guarantees of origin. Carbon emissions should be reflected over the whole lifecycle of hydrogen. Origin schemes need to include clear labels for hydrogen and hydrogen products to increase consumer awareness and facilitate claims of incentives.
• Governance system and enabling policies. As green hydrogen becomes mainstream policies should cover its integration into the broader energy system. Civil society and industry must be involved to maximise the benefits.
• Subsequent briefs will explore the entire hydrogen value chain providing sector-by-sector guidance on the design and implementation of green hydrogen policies.

This study seeks to answer a simple question: will we have enough renewable electricity to meet all of the EU's decarbonisation objectives and if not what should be the priorities and how to address the remaining needs for energy towards carbon neutrality? Indeed if not the policy push for green hydrogen would not be covered by enough green electricity to match the “energy efficiency and electrification first” approach outlined in the system integration communication and a prioritization of green electricity uses complemented by other solutions (import of green electricity or sustainable fuels CCS...) would be advisable [1]. On one hand we show that the principle “Energy efficiency and electrification first” results in an electricity demand which will be very difficult to satisfy domestically with renewable energy. On the other hand green hydrogen and other sustainable fuels will be needed for a carbon neutral industry for the replacement of the fuel for aviation and navigation and as strategic green energy reserves. The detailed modelling of these interactions is challenging given the large uncertainties on technology and infrastructure development. Therefore we offer a “15 minutes” decarbonization scenario based on general and transparent technical considerations and very straightforward “back-of-envelope” calculations. This working paper contains the calculations and assumptions in support of the accompanying policy brief with the same title which focuses instead on the main take-aways.

The policy module of the FCHO presents an overview of EU and national policies across various hydrogen and fuel cell related sectors. It provides a snapshot of the current state of hydrogen legislation and policy. Scope: While FCHO covers 38 entities around the world due to the completeness of the data at the moment of writing this report covers 29 entities. The report reflects data collected January 2019 – December 2019. Key Findings: Hydrogen policies are relatively commonplace among European countries but with large differences between member states. EU hydrogen leaders do not lag behind global outliers such as South Korea or Japan.

The utilization of hydrogen energy is important for achieving a low-carbon society. Japan has set ambitious goals for hydrogen stations and fuel cell vehicles focusing on the introduction and dissemination of self-refuelling systems. This paper evaluates public trust in the fuel equipment and self-handling technology related to self-refuelling hydrogen stations and compares it with that for widespread gasoline stations. To this end the results of an online survey of 300 people with Japanese driver licenses are reported and analyzed. The results show that trust in the equipment and self-handling is more important for the user than trust in the fuel. In addition to introduce and disseminate new technology such as hydrogen stations users must be made aware of the risk of using the technology until it becomes as familiar as existing gasoline station technology.

In its new report Making the Hydrogen Economy Possible: Accelerating clean hydrogen in an electrified economy the ETC outlines the role of clean hydrogen in achieving a highly electrified net-zero economy. The report sets out how a combination of private-sector collaboration and policy support can drive the initial ramp up of clean hydrogen production and use to reach 50 million tonnes by 2030.<br/>Clean hydrogen will play a complementary role to decarbonise sectors where direct electrification is likely to be technologically very challenging or prohibitively expensive such as in steel production and long-distance shipping. The report highlights how critical rapid ramp-up of production and use in the 2020s is to unlock cost reductions and to make mid-century growth targets achievable.<br/>This report is part of the ETC’s wider Making Mission Possible Series – a series of reports outlining how to scale up clean energy provision within the next 30 years to meet the needs of a net-zero greenhouse gas emissions (GHG) economy by mid-century. The reports in the series analyse and set out specific actions required in the next decade to put this net-zero by 2050 target within reach.
