Battery storage stands out in Japan clean power auction

Japan's first auction for long-term zero emissions power capacity has attracted strong bidding interest with a plan to install battery storage, as investment in the power storage system is gaining momentum in line with expanded use of fluctuating renewable energy sources.

Japan launched the clean power auction system from the April 2023-March 2024 fiscal year, aiming to spur investment in clean power sources by securing funding for fixed costs in advance to drive the country's decarbonisation by 2050.

The first auction, which was held in January, has awarded 1.1GW capacity for battery storage, or 27pc of total contract capacity for clean power sources, excluding gas-fired generation that has been temporally included in the auction system to help ensure stable power supplies, nationwide transmission system operator Organisation for Cross-regional Co-ordination of Transmission Operator (Occto), which manages the auction, said on 26 April.

Bidding capacity for battery storage totalled around 4.6GW, the highest volume among any other clean power sources. This means the contract ratio for storage batteries was 24pc compared with the 100pc ratio for ammonia co-firing, hydrogen co-firing, biomass dedicated and nuclear capacity, along with gas-fired capacity.

Awarded capacity for battery storage as well as pumping-up electric power facilities reached 1.67GW, exceeding the 1GW sought by the auction.

Japan has secured a total of 9.77GW of net zero capacity through the 2023-24 auction. Contract volumes covered 1.3GW of nuclear, 199MW biomass, 577MW of pumping-up electric power, 770MW for ammonia co-firing and 55.3MW hydrogen co-firing, as well as 1.1GW of battery storage. This also included 5.76GW of gas-fired projects.

All winners under the auction can generally receive the money for 20 years through Occto, which collect money from the country's power retailers, although they need to refund 90pc of other revenue. The first auction saw total funding of ¥233.6bn/yr ($1.51bn) for decarbonisation power sources and ¥176.6bn/yr for gas-fired capacity.

Japan's battery requirements are expected to continue rising, with uncertainty over future nuclear availability likely to spur Tokyo to accelerate the roll-out of renewable energy to meet a 46pc greenhouse gas emissions reduction by 2030-31 against 2013-14 levels — a target still far above the 23pc recorded in 2022-23. Japan will need to install 38-41GW of renewable capacity, nearly triple actual output of 14GW in 2019.

Japan is looking to establish lithium-ion battery production capacity of 150GWh/yr domestically and 600GWh/yr globally by 2030. The trade and industry ministry projects the latter target will require 380,000 t/yr of lithium, 310,000 t/yr of nickel, 600,000 t/yr of graphite, 60,000 t/yr of cobalt and 50,000 t/yr of manganese.

Q&A: US' ACE Green bets on LFP batteries

Singapore, 9 May (Argus) — US-based battery recycler ACE Green Recycling has been focusing on the US market, particularly its upcoming Texas recycling site, and plans to run its lead-acid and lithium-iron-phosphate (LFP) battery recycling operations alongside each other in Texas. Argus spoke with ACE Green Recycling's vice-president of investments and strategy, Aaron Wee, about their Texas site, battery recycling gate fees in Europe and the black mass market. The interview is split into two parts and part two's edited highlights follow: What's your view on the US market? The US market for lead is [one of] the most attractive market in the world. It's where you can find possibly some of the cheapest scrap batteries for lead, and also get some of the highest premiums on refined and alloyed lead. In terms of lithium, obviously the US is either the second- or the third-largest economy for [electric vehicles] and lithium batteries in general. Nowadays, with the improvements in LFP battery technology, the range and energy density problems of the past are now not really an issue. We sort of predicted the shift towards LFP quite some time ago. Back when the recyclers were concerned about nickel-manganese-cobalt (NMC) because we're going to get nickel, we're going to get cobalt. That was a relatively easy win for a lot of recyclers. But for us, LFP was always going to be the battery of the future. In fact, in our Texas project, we've already [begun the process of acquiring] the land and the facilities to combine both our battery recycling technology stacks and to co-locate them in a single location. But lead will start first because lead is going to make money tomorrow. LFP might take a little bit of time before feedstock actually comes in. What does ACE think of gate fees, especially in Europe? Does it distort the long-term consideration when setting up battery recycling operations? From a commercial point of view, I think depending on the battery type, that would be €500-800/t of batteries for gate fees in Europe. This may or may not hold over the next couple of years as more recycling capabilities are deployed in Europe. We won't say no to just getting money to recycle them. But our ultimate goal is not to rely on gate fees as a commercial strategy. Moving forward, I don't think any company can rely on gate fees as a strategy. It just won't be tenable. Eventually, somebody's going to be able to do it cheaper and better than you. And if you rely on gate fees, that's the end game right there. Gate fees are usually correlated with the price of lithium. [If] the price of lithium goes up, then recyclers won't [need to] rely on [gate fees]. Chances are we're going to be looking at maybe $12,000/t of lithium carbonate, [or] maybe $11,000 by the end of this year. What does ACE feel about the current pricing mechanism of black mass, battery scrap or even lithium? The correlation between lithium prices and black mass is very strong. But black mass as a commodity is a little bit trickier to export to China because of the regulations. Once they accept black mass [imports], especially LFP black mass, that will have a significant change. There will also perhaps be a fall in prices in the rest of the world because now they can sell to China, not just internally in their own domestic markets. Depending on how trade barriers may or may not come up over the next couple of months, we should see a shift in how black mass is priced.

Australian firms flag coal phase-out timeline concerns

Sydney, 9 May (Argus) — Energy utilities raised concerns that Australia's coal-fired power generation phase-out might be running on an unrealistic timeline, according to submissions to the National Electricity Market (NEM) review consultation process. Utilities AGL Energy, Alinta Energy, Delta Energy, Energy Australia, Origin Energy and Stanwell — which operate 10 of the 20 coal-fired power plants in Australia (see table) — submitted separate recommendations to the consultation launched late last year looking at wholesale market settings. This came after the conclusion of the Capacity Investment Scheme (CIS) tenders in 2027, and as Australia transitions to more renewables from its aging coal-fired plants. The Australian Energy Market Operator (Aemo) forecast the country will exit all coal-fired generation by 2038 in its Integrated System Plan (ISP) published in 2024. But Delta Energy predicts that this timeline will not be met, and views ISP's priority as emissions reduction targets rather than a realistic timeline. Insufficient capacity to replace the coal plants was a common issue flagged by these companies, with AGL saying this is partly because of uncertainty in the market leading to less investments. The utility plans to close all its coal plants by the end of June 2035. AGL was Australia's largest emitter of greenhouse gas emissions in the 2024 financial year, according to the Clean Energy Regulator (CER), followed by Stanwell, Energy Australia and Origin Energy. The transition could be supported using flexible dispatchable resources, according to Origin Energy. The coal phase-out means more variable renewable energy (VRE) is required, but VRE output will not necessarily match demand. "The NEM review must also consider the actions to facilitate the planned retirement of coal-fired power stations from the energy system, which will still be occurring in the NEM beyond the CIS," Stanwell warned. "The urgency of developing solutions cannot be overstated, as any indecision now would result in increased government intervention later, and a disorderly and costly NEM beyond the CIS." Gas-fired generation A few firms view gas-powered generation as critical in the transition away from thermal coal and in maintaining system reliability. It will provide back-up in times of renewable droughts, said Stanwell and AGL, and should be noted in discussions of the forward strategy. But Alinta Energy is cautious of the costs of gas-fired power plants, believing them to be the least costly for customers but not economically viable because of their exposure to global gas market prices. Alinta's suggestion is to reduce the market's dependence on high-cost facilities including gas-fired facilities. Mixed views on capacity market Some companies mentioned a capacity mechanism as a solution. Coal-fired facilities should be allowed to continue until they can be replaced, said Alinta Energy, and gas power plants are necessary. Energy Australia and Delta are calling for the NEM to stay technologically neutral in this process, keeping thermal coal exits in mind. A capacity market needs to be sustainable without government subsidies, Alinta Energy said, and exit strategies for government intervention should be clear from the beginning. But capacity markets can lead to higher costs for customers, according to AGL, because of potential over-procured capacity. "If a capacity mechanism was implemented, it would be important to consider the impact of any capacity incentive on the operation of the NEM and the appropriate level of the market price settings — a balance that may be difficult to strike," AGL noted. The expert independent panel leading the review will continue carrying out consultation, and is expected to make final recommendations to energy and climate ministers in late 2025.

Mitsubishi joins Philippine coal plant phaseout project

Osaka, 9 May (Argus) — Japanese trading house Mitsubishi has agreed to join a project to phase out a coal-fired power plant in the Philippines, aiming to generate carbon credits through the Transition Credits mechanism along with Japan's Joint Crediting Mechanism (JCM). Mitsubishi and and its Hong Kong-based subsidiary Diamond Generating Asia (DGA) has agreed to join Philippine energy firm Acen, GenZero — a subsidy of Singapore state-owned investment firm Temasek — and Singapore conglomerate Keppel to phase out the 246MW South Luzon coal-fired plant in Batangas, the Philippines, and replace it with a clean power facility. The initial deal for this project was signed by Acen, GenZero and Keppel in August 2024. Acen is now seeking to decommission the coal-fired plant by 2030, instead of the previous target of 2040. It is still unclear what types of clean power sources will then be deployed. But renewables such as solar or onshore wind, alongside storage batteries, could be possible, a Mitsubishi spokesperson told Argus . The partners aim to leverage Transition Credits (TCs) for the early retirement of the plant. TCs are high-integrity carbon credits generated from the emissions reduced through retiring a coal-fired plant early and replacing this with clean energy. The South Luzon project is expected to be one of the first converted coal-fired plants in the world to generate TCs. The project is expected to generate carbon credits equivalent to 19mn t of CO2 emissions reduction over 10 years, the Mitsubishi spokesperson told Argus . Mitsubishi plans to include this project in the JCM mechanism, as the Philippines has been Japan's JCM partner country since January 2017. The company is already marketing the carbon credits in Japan, assuming the credits will be verified under the JCM, while also hoping to sell them in Singapore and the Philippines. Verified carbon reductions or removals under the JCM can be quantified on an international basis. Some of the JCM credits issued from such mitigation efforts will be used to achieve Japan's nationally determined contributions (NDCs), while ensuring double counting is avoided on the basis of corresponding adjustments between countries and consistency with the guidance on co-operative approaches referred to in Article 6.2 of the 2015 Paris climate agreement. JCM credits could be also traded under the Japan's green transformation emission trading system (GX-ETS), which will be officially launched in autumn of 2027 . The GX-ETS adopts the cap-and-trade programme, with the government allocating free allowances for each eligible entity every year. Japan is still highly dependent on coal-fired generation, although Tokyo has pledged to phase out inefficient coal-fed plants by 2030. Coal-fired output accounted for 32pc of the country's total power generation in 2024, according to data from the trade and industry ministry. When asked by Argus where there is the potential for the introduction of the Transition Credits mechanism in Japan, the spokesperson said Mitsubishi has not ruled out the possibility, but added there have been no discussions on this for now.

Japan’s Erex to build biomass power plant in Cambodia

Tokyo, 8 May (Argus) — Japanese renewable energy developer Erex aims to start constructing a 50MW biomass-fired power plant in Cambodia in mid-2025, the company told Argus today. The plant in southern Cambodia's Kampong Speu province will be the first biomass-fired power project for Erex in the country. It is scheduled to start commercial operations in the 2027-28 fiscal year, and will burn domestic wood chips and agricultural residues to generate around 350 GWh/yr. The Cambodian government will purchase all the electricity generated at the plant for 25 years after its start-up. Erex plans to build up to five biomass-fired power plants which will burn domestic biomass fuels, as well as several wood pellet factories in Cambodia. The government expects these projects to raise the country's energy security. Erex on 23 April began commercial operations at the 20MW Hau Giang biomass-fired power plant in southern Vietnam, its first biomass-fired power project in the country. Erex aims to construct up to 18 biomass-fired power plants in Vietnam, following Hau Giang. The company has already started constructing two 50MW plants in northern Vietnam. Erex also started wood pellet production at its first factory in Vietnam in March, with a capacity of 150,000 t/yr. The company plans to build up to 20 wood pellet factories in the country. Erex's profits from projects in Vietnam and Cambodia are expected to grow rapidly and could account for more than half of its total profits by around 2030, according to the company, and the projects would also contribute to both countries' decarbonisation efforts.

Australian renewable projects gain power grid access

Sydney, 8 May (Argus) — A total of 10 renewable energy projects have been granted access to a power grid in New South Wales (NSW), Australia, to avoid over 10mn t/yr of CO2 equivalent (CO2e) of emissions by 2031, the NSW state government said today. The 10 private solar, wind and battery storage projects will connect to the Central-West Orana Renewable Energy Zone (REZ) , a 20,000 km² area about 400 km west of state capital Sydney that will avoid 10.29mn t/yr of carbon emissions, according to the state's energy minister. Construction of the 240 km transmission line connecting the renewable energy projects to the national electricity market will start in mid-2025 and is estimated to cost A$3.2bn ($2.1bn). The 10 projects will provide total renewable energy and storage capacity of 7.15 GW, capable of powering over half the households in NSW by 2031. The Central-West Orana REZ is expected to be completed by December 2028 and is part of the NSW's transition to renewable energy. The REZ is expected to generate 15,000 GWh/yr of energy when fully operational, around 5pc of the total 273,000 GWh generated in the country in 2023, according to the Australian Department of Environment. The REZ improves the state's chances of meeting its target of reducing emissions by 50pc from 2005 levels by 2030 through lowering its reliance on coal-fired generation, which accounted for 70pc of fuel used in NSW in May 2024-April 2025. Australia's largest coal-fired power station Origin's 2,880 MW Eraring provides 18pc of the state's electricity and will close in August 2027, around a year before the expected completion of the Central West Orana REZ project.
