Ammonia, Subscriber Content Weekly Roundup 2025 June 20 News in Brief ### June 23 – The US Supreme Court has ruled that fuel industry groups have legal grounds to challenge the Environmental Protection Agency (EPA) waiver that allowed California to implement its Advanced Clean Car I standards. The ruling challenges California’s quest to implement separate, more stringent pollution standards. ### June 20 – Rental power market in the UK, valued $335 million in 2024, is projected to grow at a rate of more than 5% and reach $451.10 Million by 2030. According to the Europe Rental Association (ERA), the power rental segment is highly fragmented, with the top four companies holding only one-third of the market. ### June 18 – Moody’s has rated Siemens Energy AG as ‘investment grade’ at Baa2 with a positive outlook (+) in its inaugural rating which affirms the company’s creditworthiness.In its rating, Moody’s noted Siemens Energy’s leading market positions, its broad geographic and product offering, the positive long-term market fundamentals alongside a growing order backlog and its strong liquidity profile and conservative financial policy. ### June 16 – Pratt &amp; Whitney (P&amp;W) has celebrated 100 years of innovation, highlighting its aeroderivative gas turbines which deliver high efficiency, fast starts, and low emissions for power generation. Over 2,000 aeroderivative units have been deployed globally, providing up to 60 MW each. ### June 6 – The former MAN Energy Solutions is now operating under a new name and has become ‘Everllence’. The company remains part of the Volkswagen Group, and its product and service portfolio stay unchanged. ### June 3 – MET Energia Italia and Eredi Gnutti Metalli have entered a 10-year Power Purchase Agreement (PPA) to offtake wind energy at a fixed price. The volume of electricity supplied under the PPA represents about 9% of the energy needs of Eredi Gnutti’ Brescia-based metallurgy plants. ### June 2 – California Independent System Operator (CAISO), the grid operator for most of the state, is increasingly curtailing solar- and wind-powered electricity generation as it balances supply and demand amidst rapid renewables capacity growth. In 2024, CAISO halted the dispatch of 3.4 million MWh of wind and solar output, a 29% increase year-on-year. ### May 30 – Wärtsilä is partnering with a power plant in the Brazilian city of Recife with a view to running a 4 MW engine on ethanol for 4,000 hours during a two-year pilot starting in April 2026. The Finish engine maker claims the tests will be ‘world-first trial’ in generating electricity with an ethanol-powered engine, though Petrobras and Vale ended a similar trial over high costs and low uptake. ### May 29 – Capstone’ Australian distributor, Optimal Group, has been selected as EPC contractor for a remote community power generation project in the Oceania region. Two Capstone C1000S microturbines will deliver an initial 2 MW of electricity to an isolated community, with the system designed to be scaled up 5 MW of power. ### May 27 – Extensive testing of Wärtsilä 4-stroke engine for ammonia fuel have helped optimise performance. Co-firing a 95% ammonia energy share now achieves up to a 90%reduction in greenhouse gas emissions compared to equivalent diesel engines. Recent tests proved ammonia to be a suitable fuel for the low-pressure Otto cycle concept, which Wärtsilä uses for dual-fuel engines running on LNG. ### May 23 – Kerrville Public Utility Board (KPUB) has selected MAN Energy Solutions to supply six 18V51/60G gas engines, providing a total capacity of 124 MW. The gas engines are used in a peak-load power plant in Texas, increasing grid stability. ### May 21 – ProPetro Holding’s PROPWR division has secured its inaugural contract to commit 80 MW of power generation capacity for a Permian-focussed E&amp;P operator starting from the third quarter of this year through 2026. Electricity will be supplied to a distributed microgrid installation, utilizing in-field gas. ### May 19 – Natural gas prices in the US are set to rise in the coming months as more LNG gets exported and gas-burn in the electric power sector increases seasonally. Government analysts forecast Henry Hub spot price will average nearly $4.20/MMBtu in the third quarter of 2025 – almost double the price from a year earlier. ### May 15 – Mitsubishi Heavy Industries (MHI) has installed and commissioned a new carbon capture pilot project at KEPCO’s Himeji No.2 power plant Japan. The LNG-fuelled plant consists of 6 units and has a maximum output of 2,919 MW. ### May 14 – New Fortress Energy (NFE) has executed a three-year charter agreement for the Energos Freeze FSRU, with Energía 2000 in the Dominican Republic. The 125,000 cbm floating storage and regas unit will be deployed at port of Manzanillo and is due operational in September 2025, providing fuel for local power generators and industry. ### May 13 – US electricity customers in states such as Hawaii and Connecticut paid more than $200 per month for electricity in 2024 – more than twice as much as customers in states such as New Mexico and Utah. According to the EIA, the average electric monthly bill for U.S. residential customers was $144. ### May 12 – Sembcorp has been contracted to provide gas, electricity and utility services to Aster Chemicals and Energy. The deal is worth at more than 650 million Singapore dollars (US$500.23 million), with works focussing on Aster’s refining and chemical facilities on Pulau Bukom and Jurong Island. ### May 8 – Reliance NU Suntech, part of Reliance Power, has sealed a 25-year power purchase agreement with Solar Energy Cop of India (SECI) to deliver 930 MW of electricity. The intermittent solar power supply will be backed up by a 465 MW/1,860 MW battery energy storage system – all at a fixed tariff of 3.53 Indian Rupees (₹) per kWh. ### May 7 – Hitachi Energy will deliver the world’s first sulfur hexafluoride (SF6)-free 550 kV gas-insulated switchgear to the Central China Branch of the State Grid Corporation of China (SGCC). The move towards clean switchgear helps decarbonize the Chines power grid and contributes towards the country’s target of reaching carbon neutrality by 2060. ### May 5 – French cleantech firm Revcoo, a French cleantech start-up, has developed a new technology to capture CO2 directly from factory chimneys.
