ClearVue Technologies Limited (ASX: CPV)

has reported a transformative Q4 FY25 which is marked by major leadership renewal and collaborations to drive global growth and product innovation. Operational highlights included a two-year partnership with engineering leader erbasTM to integrate solar façades into sustainable building projects and a successful trial at Hong Kong’s EMSD headquarters demonstrating payback periods as low as 2.6 years and the potential to generate up to 125% of a building’s energy needs.

The company also formed a partnership with LandVac to co-develop solar vacuum insulated glazing, secured an approximately $600,000 contract for Sydney’s City Tattersalls Club redevelopment and entered the New Zealand market via a manufacturing and distribution agreement with Viridian Glass. ClearVue is contributing to a $20 million RMIT led smart greenhouse research project and ended the quarter with $3.7 million in cash after $1.34 million in net operating outflows primarily from R&D, manufacturing, marketing and staffing.

Carnegie Clean Energy Limited (ASX: CCE)

has reported significant progress in the quarter ended 30 June 2025, centered on advancing its ACHIEVE Programme which is key to commercializing its CETO wave energy technology. Major milestones included electrical and control system testing at SEI, manufacturing partnerships such as with SKF for Power Take-Off units and pre-deployment preparations at the Biscay Marine Energy Platform (BiMEP) in Spain. The company signed Memoranda of Understanding with BiMEP to develop a 6MW CETO wave energy array in Europe and with Chugachmiut to explore wave energy applications in remote Alaskan communities. In addition to that, Carnegie received €1.6 million in payments supporting the first European CETO deployment and continued its research collaboration with the University of Adelaide to improve control systems. Parallel to CETO, the MoorPower technology advanced with funding awarded for preliminary design work aimed at commercial aquaculture market deployment.

Carnegie ended the quarter with approximately $2.9 million in cash reserves after net operating outflows of $843,000 mainly relating to R&D, manufacturing, marketing and staffing. Investing activities generated a net cash inflow of $1.24 million and financing activities consumed $130,000. The company maintains a loan facility of $2.5 million due June 2026. Strategic investor engagement efforts continued with roadshows in Europe and North America to broaden its investor base and support commercial momentum. Carnegie's focus remains on delivering its ACHIEVE milestones, optimizing manufacturing and supply chains and scaling up commercial applications in both wave energy and related offshore markets.

Meridian Energy Limited (ASX: MEZ)

experienced strong hydro inflows and water storage levels through June 2025 with national hydro storage rising from 94% to 104% of the historical average by mid-July. The company’s June total inflows were 111% of the historical average helping keep catchment storage healthy including Waiau catchment inflows at 113% of average and Waitaki catchment storage at 87% of average. June generation increased 6.1% year on year which was driven by higher hydro and wind output despite a 54.2% decline in the average generation price compared to June 2024. National electricity demand in June rose 1.4% versus the previous year and is supported by greater retail sales volumes across most segments which were 7.9% higher compared to June 2024.

For Q4 FY25, Meridian's total inflows were 102% of the historical average which were 19% above Q4 last year with Waitaki catchment storage also up 37%. However, generation was 8.8% lower than the prior year’s Q4 amid an 18.6% decline in average electricity prices. Retail customer connections rose 9.6% year over year with total retail sales volumes up 2.9% at a 5.2% higher average price. Operating costs remained largely flat compared to the previous Q4 while capital expenditure was down 16.5%. Meridian announced an agreement with New Zealand Aluminium Smelters to end a demand response arrangement targeting completion by mid-August. The company continues to focus on managing generation, price variability and maintaining resource resilience amid evolving market and climatic conditions. In addition to that, Meridian recently agreed with major generators on a strategic energy reserve at Huntly Power Station to enhance system security and address fuel supply risks over the coming decade.

Mercury NZ Limited (ASX: MCY)

has reported FY25 generation of 7,906GWh which was down 11% from the prior year, reflecting lower hydro, wind and geothermal output. Hydro generation of 3,410GWh was 17% lower driven by 12th percentile Waikato catchment inflows and a below average Lake Taupō starting level. Wind generation fell 6% to 1,936GWh on reduced wind speeds while geothermal was 2% lower at 2,559GWh due to planned outages. In Q4 FY25, low lake levels and dry conditions early in the quarter reduced hydro output to 864GWh but late period inflows lifted catchment inflows to the 79th percentile improving storage heading into FY26. Market conditions saw average Auckland spot prices at $216/MWh in the June quarter with forward prices easing to $179/MWh for FY26–FY27.

The completion of the Karāpiro Hydro Rehabilitation Project in September 2025 will conclude a three-year programme, increasing hydro capacity by 16.5MW and delivering an estimated 32GWh in additional annual output. Mercury’s AI-powered Digital River platform has already boosted hydro efficiency with expected mean annual hydro generation lifted to 4,140GWh. Customer connections continued to grow with 578,000 electricity ICPs, 206,000 broadband/mobile services and 215,000 multi-product customers as at 30 June 2025. The company remains focused on cost discipline, operational efficiency and advancing its renewable generation pipeline targeting 3.5TWh of new output by 2030.

The company advanced its zero-emission vehicle and hydrogen infrastructure strategy with key milestones including the delivery of Australia’s first fully registered hydrogen prime mover to Barwon Water and the signing of a Master Supply and Distributor Agreement with GreenH2 LATAM, positioning it as preferred supplier for two major hydrogen projects in Mexico worth US$28 million.

New hybrid product designs like the HD100C Hybrid Coach and TG23 Hybrid Low Cab Rigid Truck were completed, targeting cost conscious operators transitioning to clean transport. The company remains focused on commercialising its vehicle pipeline, scaling hydrogen infrastructure sales globally and leveraging partnerships to drive growth across both domestic and international markets.
