Germany steps up hydrogen production infrastructure
Germany is stepping up its hydrogen production infrastructure, as the economy and energy ministry this week announced a second round of calls for hydrogen test fields
The economy and energy ministry's head of energy policy Thorsten Herdan said that the second call for projects to qualify as test fields will be issued before parliament dissolves in the summer, ahead of federal elections in September.
Test fields will become a "fixed part of the energy transition, and of [the government's] energy research policy", Herdan said at the inauguration of the hydrogen "northern field test" (NRL) covering the states of Hamburg, Schleswig-Holstein and Mecklenburg Western Pomerania.
The NRL project is one of 20 field tests that qualified in the first round of calls.
"Green hydrogen will be needed in quantities impossible to conceive," federal economy and energy minister Peter Altmaier said at the NRL inauguration. Altmaier added that it is not about whether hydrogen will be produced in Brazil or in Morocco or in other countries, "but it is about [hydrogen] being produced all over the world".
The NRL field test, made up of 25 individual projects, was awarded €52mn ($62mn), of total investment costs of €300mn borne by the partners, which include utilities and industry companies. NRL will make an "important contribution to the roll-out of Germany's hydrogen infrastructure", Altmaier said.
NRL includes plans for eight electrolysers with a total electrolysis capacity of 42MW. This will make it possible for the north's strong winds to be used by industry, including Europe's largest copper producer Aurubis, based in Hamburg, and for heating and transport uses, the city state of Hamburg's prime minister Peter Tschentscher said. Tschentscher pointed out that Germany's north must curtail around 3TWh of renewable power every year due to grid bottlenecks.
Junior energy minister at the economy and energy ministry Andreas Feicht said that projects such as NRL will "lead to the development of processes, products and models", which will make it possible "for us not just to have and to use hydrogen, but also to have low-cost hydrogen".
Herdan said the needs of the hydrogen customer, "the customer's point of view", will now increasingly be at the centre.
Disagreement persists in Germany over the extent to which hydrogen consumption should be rolled out, over the role that should be given to other types of hydrogen — such as "blue" hydrogen — or to imported hydrogen, and whether to locate electrolysers close to renewables generation sites, or close to off-takers.
NRL manager Werner Beba said that Germany should first build up its hydrogen industry "on a large scale", and "then think about imports".
Olaf Lies, the energy and climate minister of Lower Saxony, also a northern state, this week said that the "correct order" should not be to first extend green hydrogen production, and to decarbonise only once there is enough green hydrogen in the system. Rather, blue hydrogen — produced from natural gas, of which the carbon is sequestered and stored — will be necessary for an interim period, Lies said.
The federal government so far supports green hydrogen only, including imports of green hydrogen.
Research institute Fraunhofer IEG acting director Mario Ragwitz this week at an event of the opposition Green Party suggested that Germany, or Europe, take up a "pioneering role" in developing guarantees of origin for green hydrogen.
Ragwitz cautioned that the domestic uptake of hydrogen remains unclear in some sectors, for instance the heating sector.
Germany's competitiveness is also viewed as an increasingly pressing issue. Tschentscher voiced his fears of Germany being left behind by Japan and China regarding hydrogen technology. "But when I look at the test field, then I feel that maybe we won't be left behind," he said at the inauguration.

Fire-hit biomass plant in Japan to start up in 2025
Fire-hit biomass plant in Japan to start up in 2025
Tokyo, 3 July (Argus) — Japan's 75MW Sodegaura biomass-fired power plant, operated by Osaka Gas, will begin commercial operations around April-September 2025, following delays caused by a silo fire in January 2023. The fire at the Sodegaura plant in Chiba prefecture happened during test runs, and Osaka Gas said on 3 July that the cause was the combustion of wood pellets stored for more than six months in two silos. The company has now put in place measures to reduce the risk of fires, including a nitrogen injection system that can prevent temperature increases. Other measures include bringing pellets out of silos to lower their temperature every three months or so, with the exact duration depending on the season and other conditions. The plant was initially supposed to begin commercial operations by the end of February 2023, but start-up was delayed by the fire. Osaka Gas only managed to put the fire out completely in May 2023. The company finished removing all remaining pellets from the silos in April this year — the pellets had absorbed sprayed water and swelled.

Washington advances carbon market linkage plans
Washington advances carbon market linkage plans
Houston, 2 July (Argus) — Washington regulators are moving forward with plans to further align the state's cap-and-trade program with the California-Quebec carbon market. The state Department of Ecology has released for public comment two draft rules related to holding limits, biofuel emissions and electricity imports that are intended to smooth the way for linkage ahead of formal discussions with California and Quebec regulators that could kick-off next year. The first draft rule, issued on Monday, would revise general cap-and-trade program mechanics, such as raising the holding limit for allowances issued each year for general market participants to 25pc from 10pc should the programs link. It would also revise emissions exemption for biofuels, recently authorized by state lawmakers, of 30pc lower greenhouse gas (GHG) emissions than comparable petroleum fuels and allow Ecology to add an exemption standard used by a linked program, for a two-part standard. Washington set the ball rolling on its ambition to link with the Western Climate Initiative (WCI) partners California and Quebec last year in hopes that creating a larger North American carbon market will help reduce compliance costs. The state legislature authorized Ecology to make the changes in legislation adopted earlier this year . The program costs became a significant issue last year, when Washington Carbon Allowances (WCAs) rose as high as $70/metric tonne (t) in the secondary market. California and Quebec agreed in March to explore adding Washington to the WCI, but progress is unlikely to happen this year as California regulators first focus on updating the state's cap-and-trade program. In the interim, Ecology said it is still considering other amendments that could help with linkage, including moving the state's compliance periods, which run on a four-year cycle, to the three-year cycle used in the linked market. But California and Quebec are considering shifting their compliance periods to either four years or two years for 2026-2030, and then to either five years or alternating between three-year and two-year periods after 2030 to align with their respective statutory targets, which Ecology will have to take into account. Washington has set a target to cut GHG emissions by 45pc by 2030 compared with 1990 levels, and reach net-zero emissions by 2050. The program cap-and-trade program covers industrial facilities, power plants, natural gas suppliers, and other fuel suppliers with emissions of at least 25,000 t/yr. Ecology is accepting feedback on its linkage rulemaking through 27 September, with a public meeting set for 10 July. Imports and reports In a separate rulemaking announced last week, the state is considering expanding reporting requirements and covered emissions under the program to included imported electricity from centralized electricity markets (CEM). The state is required under its Climate Commitment Act to adopt a methodology for imported electricity by 1 October 2026. The proposed amendments would come into play in 2027, allowing regulators to assign GHG emissions to imports of electricity from CEM and for the state to better understand how the imports may affect its climate goals. Under the proposed amendments, regulators would increase allocations of no-cost allowances to electric utilities. The state issues no-cost allowances to electric and natural gas utilities, and industrial entities, to mitigate the cost of decarbonization. Electric utilities must consign an increasing portion of these allowances to state auction starting in 2027 and must use this revenue for projects to benefit customers through projects like energy transition billing credits. Regulators estimate that bringing CEM importers under the cap-and-trade program will result in an aggregated annual compliance cost of around $7mn-$119mn, depending on allowance prices, which regulators expect will fall as emissions declines outweigh imports over time, according to a preliminary regulatory analysis released last month. The proposed changes reflect estimates last year by the state Department of Commerce that 43pc of the state's electricity supply by 2050 will come from imports, driven by Washington moving its electricity away from fossil fuels to renewables sourced from within and outside the state to meet the goal of decarbonizing the state's grid by 2045. Ecology will accept feedback on its proposed rules for imported electricity through 20 August, with final adoption planned in December.

French EdF develops more nuclear supply contracts
French EdF develops more nuclear supply contracts
Paris, 2 July (Argus) — French state-owned utility EdF has signed five letters of intent for long-term nuclear supply contracts for power-intensive industries, EdF executive director Marc Benayoun said at the Europ'Energies conference in Paris today. The five nuclear power supply contracts represent over 10 TWh/yr of consumption and will last for at least 10 years. Payment will be upfront. "We are still far from the [24TWh] maximum that we were aiming for but, in a context of low prices, some actors prefer medium-term contracts", Benayoun said. The utility had signed three letters of intent for nuclear power supply contracts as of April, including one with steel manufacturer Arcellor Mittal and another with green iron consortium GravitHy . French nuclear power supply contracts — or CAPNs — are designed for power-intensive industries, defined by the share of energy expenses in their revenue. French state-owned rail company SNCF consumes an average of 9 TWh/yr of power so does not fall under the power-intensive category, making it ineligible for a CAPN. Discussions on widening the scope of CAPNs have been ongoing with EdF, SNCF operations director Khadidja Haned Bouaddou told Argus . Nuclear supply contracts will partly replace France's Arenh scheme, under which EdF is obliged to sell nuclear power at a fixed price to competitors. The Arenh mechanism is due to expire at the end of next year. The French state reached a deal with EdF at the end of last year that sets a price for nuclear power sales, but the agreement has not yet become law. The prices of the contracts could be renegotiated, French economy minister Bruno Le Maire said recently. France's current parliamentary elections add further uncertainty to the future of the mechanism. EdF has concluded 2,000 contracts for around 40TWh, or 11.7 TWh/yr, of power over 4-5 years, with the power coming not only from its nuclear fleet. This compares with the 20TWh of power that the utility had sold as of the beginning of April . In parallel, the utility is conducting pay-as-clear auctions for delivery in 2028-29, offering 1-5MW. But the auction has not cleared, as prices have decreased and bids received by EdF were below its reserve price, Benayoun said. Power-intensive industries union Uniden president Nicolas de Warren welcomed the initiative of the auctions and said they represent a complementary source of supply.

Italy’s NECP eyes 11pc of power demand from nuclear
Italy’s NECP eyes 11pc of power demand from nuclear
London, 2 July (Argus) — Italy aims to generate at least 11pc of its power demand from nuclear energy by 2050 and could double that amount if necessary as part of efforts to meet its climate goals. In its new national energy and climate plan (NECP) sent to Brussels yesterday, Rome said its "conservative" scenario envisioned installing 8GW of nuclear power capacity using mainly small modular reactors but also fusion plants. Italy could build as much as 16GW of nuclear capacity depending on developments across the energy system, according to the document. The ‘with-nuclear' option would provide savings of around €17bn ($18.3bn) compared with not using it. It would also mean less gas consumption tied to carbon capture and storage (CCS) technology. Italy banned nuclear power in a referendum in 1987 after the Chernobyl disaster, but the current right-wing government of Giorgia Meloni has voiced its support for the technology. Last year it set up the national platform for sustainable nuclear power to map out a timeline for a possible return to nuclear power. In confirmation of targets set last year , Rome said it aimed to install a total of 131GW of renewable energy capacity by 2030, compared to 58GW in 2021, with a view to meeting 63pc of power demand and 39.4pc of total energy consumption. Most of the new capacity will be solar photovoltaic (PV), with 79GW expected to be installed driven by new subsidies and easier permitting. Wind capacity is expected to contribute 28GW, with offshore wind providing just 2.1GW. The plan envisages the development of contracts for difference (CfDs) through auctions for larger plants, as well as a framework to boost power-purchasing agreements (PPAs). Italy's NECP also maps out the development of electricity grids and cross-border interconnections. "The long-term risk is that the tight renewables penetration targets and the CfD mechanism established by the EU to deliver incentives could lead to a negative impact on spot prices, currently driven in Italy by the price of natural gas and carbon allowances," Italian broker Equita said. The current final revision of Italy's NECP comes after a cross-sector and public consultation. It was submitted to the European Commission for approval on 1 July, a day after the deadline required by EU law.
