Japan's Hokuriku starts biomass co-firing test runs

Market: Biomass, Electricity
21/06/24

Japan's utility Hokuriku Electric Power started coal and wood pellet co-firing test runs in April, the company said today.

Hokuriku has been conducting co-firing test runs using coal and imported wood pellets at the 700MW Tsuruga No.2 unit in Fukui prefecture since April, with the 700MW Nanao-Ohta No.2 unit in Ishikawa prefecture to follow suit.

The company also plans to increase biomass co-combustion rates at these two major coal-fired power plants to 15pc by the April 2030-March 2031 fiscal year, which means a total of 210MW of capacity and 1.5mn MWh/yr of output based on biomass-fired generation.

Hokuriku expects its increased biomass co-firing rates to reduce CO2 emissions by 1mn t/yr compared with emissions from coal-firing for the same output, although it did not disclose the volume of wood pellets that will be burned. The company has been co-firing with coal and domestically-produced wood chips at Tsuruga since 2007 and at Nanao-Ohta since 2010, but its total biomass ratio was under 1pc.

Trump takes aim at state climate policies

Washington, 9 April (Argus) — US president Donald Trump is threatening legal action against state climate and clean energy policies, a move that sent environmental markets sharply lower early Wednesday. Trump on Tuesday directed the Department of Justice to consider taking action against any states and local laws that hamper the development or use of domestic energy resources, with a specific focus on climate-related policies. US environmental markets stumbled in response to the president's executive order, with California Carbon Allowances (CCAs) for December 2025 delivery trading as low as $22.51/metric tonne on the Intercontinental Exchange and December 2025 Regional Greenhouse Gas Initiative (RGGI) CO2 allowances as low as $16/short ton, after being assessed Tuesday at $29.31/t and $21.52/st, respectively. California Low Carbon Fuel Standard futures on ICE also traded as low as $48/t, after going as high as $65.50/t Tuesday. Fears about the Trump order also spilled into the renewable energy certificate (REC) markets. Vintage 2026 PJM Class I traded as low as $28/MWh on the exchange to start the session, but last traded at $33/MWh. Argus assessed the vintage at $34.60/MWh on Tuesday. Trump's order specifically calls out California's cap-and-trade program, as well as "extortion laws" from New York and Vermont that seek to levy fees against fossil fuel companies for responsibility for historical GHG emissions. Such climate "superfund" laws are also being considered by a number of other states. But he also suggests state permitting decisions and other laws could be targeted as well. His order suggests that many of these policies run afoul of the US Constitution by imposing "significant barriers" to trade and discriminating against out-of-state energy sources, or though "arbitrary or excessive" fines. "These state laws and policies weaken our national security and devastate Americans by driving up energy costs for families coast-to-coast, despite some of these families not living for voting in states with these crippling policies," Trump said. The president directed attorney general Pamela Bondi to report within 60 days on actions she has taken against state laws and to recommend any additional action by the White House or US Congress to stop enforcement of objectionable policies. Trump unsuccessfully attempted to sever the link between the California and Quebec carbon markets during his first term, on the grounds that it violated federal authority to establish trade and other agreements with foreign entities under the US Constitution. The office of California attorney general Rob Bonta (D) said it is reviewing Trump's order, and others he issued Tuesday that aim to bolster the use of coal-fired electricity. "But this much is clear: the Trump Administration continues to attempt to gut federal environmental protections and put the country at risk of falling further behind in our fight against climate change and environmental harm," the office said. "The California Department of Justice remains committed to using the full force of the law and tools of this office to address the climate crisis head on and protect public health and welfare." California earlier this year bolstered funding for its Department of Justice in anticipation of increased legal fights with the Trump administration. New York officials also said they are considering their next steps. The state participates in RGGI and has a renewable energy mandate, but it is also developing an economy-wide carbon market. "We are thoroughly reviewing the [executive order] to determine the potential impact to New Yorkers. The governor is committed to ensuring a clean, affordable and reliable energy grid in New York state," the office of governor Kathy Hochul (D) said.

US tariffs may tighten Vietnam's wood pellet supply

US tariffs may tighten Vietnam's wood pellet supply

Singapore, 9 April (Argus) — Tariffs imposed on Vietnamese wood furniture exports to the US could pressure furniture production and tighten supply of byproducts, which are used to produce wood pellets in Vietnam. US president Donald Trump announced tariffs on nearly all US trading partners on 2 April, which took effect on 5 April, with only oil and other energy commodities exempt from the package. This means a sharp 46pc tariff has taken effect on Vietnamese exports, including wood products from the southeast Asian country. This could weaken US demand for Vietnamese wooden products, which could result in an overall cut in furniture production. Vietnam exported 53,000t of wooden furniture to the US in 2024, from 37,000t a year earlier, mirrored US customs data on furniture exports show. This accounted for nearly 12pc of Vietnam's overall wooden furniture exports last year. A drop in Vietnamese furniture exports and manufacturing would result in less process residues — such as sawdust and wood chips — made available for pellet producers. Manufacturers in southern Vietnam, which typically cater for the South Korean market, would be particularly affected because they use furniture residues as a key feedstock. But wood pellets sold to Japan, which are usually more expensive and certified for Japan's feed-in tariff market, mainly use wood chips from lumber processing as raw material. And trade data suggest that Vietnam does not export any lumber to the US, meaning there should be little impact on lumber-based wood pellet production. A drop in furniture residues would add to the pressure on an already-tight raw material market in Vietnam since the start of the year. A shortage in raw materials had caused a backlog in wood pellet loadings from before the Tet holiday in January. And unfavourable weather conditions have disrupted feedstock supply since February. It is still unclear whether the tariffs could be removed in the near future. Vietnam's secretary general of the ruling Communist Party To Lam proposed in a call with Trump on 4 April to remove all tariffs on US products. Trump posted on social media platform Truth that he looks "forward to a meeting in the near future". Impact on other biomass markets Other biomass market participants in Asia, such as palm kernel shell (PKS) traders, are also monitoring the impact from US tariffs. The most immediate risk faced is the uncertainty of foreign exchange rate fluctuations, which could hamper trading activity. But PKS traders and sellers said it was too early to determine an impact from tariffs and they have not seen any significant changes in the market, especially after the recent Idul Fitri holiday in Indonesia and Malaysia.

Trump issues executive orders to boost coal

Cheyenne, 8 April (Argus) — US president Donald Trump signed four executive orders today aimed at increasing the country's coal production and use, including directing agencies to possibly expand access to federal land and use emergency authority to keep coal-fired power plants open. The orders follow up on a pledge Trump made on 17 March to authorize his administration "to immediately begin producing Energy with BEAUTIFUL, CLEAN COAL." At the time of Trump's social media post, the White House did not elaborate on his plans. The executive orders signed today are primarily focused on US coal use and production. These include directing the chair of the National Energy Dominance Council to designate coal as a "mineral" covered under a previous executive order signed in March that uses emergency power granted under the Federal Power Act to fast track permit reviews for critical mineral projects. Today's orders also direct agencies to revoke policies that aim to move the US away from coal production or favor other generation resources over coal. This includes authorizing the Department of Justice to investigate state policies considered to be prejudicial against coal. The orders also direct agencies to identify coal resources on federal land and prioritize coal leasing on those lands, and orders the Secretary of the Interior to make it clear that a moratorium on federal coal leasing that was initially in effect from 2016-17 and reinstated from 2022-24 is no longer active. Trump also signed a proclamation allowing some coal plants to comply with a less stringent version of the EPA's mercury and air toxics standards for two years. Another order signed today directs the Secretary of Energy to "streamline, systemize, and expedite processes for issuing emergency orders under the Federal Power Act during forecasted grid interruptions." "We're slashing unnecessary regulations that targeted beautiful, clean coal" and "will end the government bias against coal", Trump said today before signing the orders at an event featuring coal miners and lawmakers from coal-producing states. The US is "going to produce energy the likes nobody has seen before." He said his administration is going to devise a "guarantee" that will ensure the industry and investment in coal projects will be protected from "the ups and downs" of politics, but did not elaborate on what that would be. Other parts of the orders have the Council of Environmental Quality assisting agencies in making some exclusions for coal under the National Environmental Policy Act, encourage coal-fired generation for artificial intelligence and call for the Secretary of Energy to consider whether coal used for steel production can be defined as a critical mineral. The orders also aim to promote coal and coal technology exports, including by possibly facilitating international offtake agreements for US coal. US coal exports rose in 2023 and 2024 but trading activity has faltered lately amid restrained steel production, limited coal-fired generation in some countries and uncertainty over recent tariffs and the US Trade Representatives proposal to charge Chinese-built and operated ships that do business in the US. The National Mining Association praised Trump's actions. "It's a stark shift from the prior administration's punitive regulatory agenda, hostile energy policies and unlawful land grabs," NMA chief executive officer Rich Nolan said before Trump signed the order. But environmental group Sierra Club warned the order will be costly. "Forcing coal plants to stay on line will cost Americans more, get more people sick with respiratory and heart conditions, and lead to more premature deaths," Sierra Club executive director Ben Jealous said.

US mid-Atlantic gas prices may rise on cold

New York, 8 April (Argus) — Spot natural gas prices across the mid-Atlantic this week may rise on an increase in heating demand resulting from colder weather. The mid-Atlantic in the week ending on 12 April was forecast to have 148 population-weighted heating degree days (HDDs), up by 37pc from a week earlier and 12pc more than the seasonal norm, according to the US National Weather Service (NWS). Below-average temperatures were expected across the northeast US, eastern midcontinent and southeastern Canada through 11 April, according to the private forecaster Commodity Weather Group. Normal seasonal weather was expected in all those regions from 12-16 April, the forecaster noted. The May price at Transco zone 6 in New York was $3/mmBtu, and the 12-month strip was $4.54/mmBtu, according to Argus forward curves. Mid-Atlantic spot prices last week rose on an increase in weather-related demand, despite the 31 March official end to the winter heating season. The Transco zone 6 New York index in the week ended on 4 April averaged $3.37/mmBtu, up by 9pc from a week earlier and 5pc higher than the April bid week price. The Tetco M-3 index over the period averaged $3.32/mmBtu, up by 10pc from a week earlier and 3pc higher than the April bid week price.

Colombia's renewables grow, but gap looms

Bogota, 7 April (Argus) — Development of non-conventional renewable (NCRE) generation has picked up in Colombia, but the pace is still not fast enough to cover a projected generation shortage by 2027-2028. Colombia will likely reach 2.55GW in installed NCRE such as solar and wind — excluding large hydropower — by the end of 2025, up from 1.88GW at the end of 2024, Colombian renewable association SER director Alexandra Hernandez told Argus at the Colombia Genera conference held last week in Cartagena. About 670MW from 19 medium and large NCRE plants worth $500mn will likely come online in 2025, Hernandez noted. Of that total, 30MW in two projects came online in January and the balance of 640MW is under construction, according to Hernandez. The plants will reduce emissions by 1.1mn metric tonnes (t) CO2/yr compared with conventional generation. For 2026, 419MW in NCRE could come online. NCRE will comprise a 12pc share of Colombia's generation capacity in 2025, up from 10pc in 2024. But Colombia will fail to meet its target of 6GW in NCRE by August 2026, when the administration of president Gustavo Petro ends, former minister of mines and energy Amylkar Acosta said. Colombia will likely will end 2026 with 3GW, Hernandez noted. This comes despite Petro's support for renewable energy and ambitions to phase out hydrocarbons use. Much of the NCRE development is focused on the dry, windswept department of La Guajira that borders Venezuela and juts into the Caribbean. US firm AES' will start building the first 259MW phase of its 1.1GW Jemeiwaa Ka'I wind complex there later this year, AES's general manager Federico Echavarria said at the Colombia Genera conference. "Our biggest bet is La Guajira," Echavarria said. Last year, Colombia's environmental regulator Anla approved a transmission line connecting 648MW of planned wind capacity in the La Guajira area to the national grid. The 500kV Casa Electrica-Colectora transmission line and substation will connect with Grupo de Energia de Bogota's 500kV Colectora transmission line. Colectora has begun construction and should come online in 2026, a delay from its original 2022 start date. La Guajira has Colombia's greatest renewable power potential, including 21GW of wind power potential, according to state planning agency UPME. But delays to key transmission projects and lengthy community consultations impeded development. Italian power company Enel suspended indefinitely construction of a 205MW wind farm in the Windpeschi region, but state-controlled oil company Ecopetrol is seeking authorization to buy it. Projects advancing in other departments include the 200MW Orquidea solar project in the Caribbean province of Bolivar, which recently earned an environmental permit that clears the way for construction. Running out of time But this new generation capacity will not cover an expected supply shortfall. Colombia is forecast to have a gap of around 2,000MW by 2027-2028 assuming baseline consumption, and 3,000MW-6,000MW if demand rises further, several electricity associations have said. Renewables could help fill this gap, as the construction is fairly quick once permits are secured, the renewables group SER said. But 47pc of renewable power companies were unable to complete their planned investments in 2024, with permitting delays among the top reason, the group found in a member survey. Permits from the government's mining and planning unit UPME takes nine months, compared with the two months stipulated by the law. Regional entities take twice as long to issue a permit than the legal limit. The government will push to do more, energy and mines minister Edwin Palma said in Cartagena. "We are convinced and committed to ensuring that expansion projects are carried out," he said. "We will work with the ministry of the interior to expedite licenses."
