EMEC Completes Tidal, Hydrogen and Battery Demonstration
turbine, vanadium flow batteries supplied by Invinity Energy Systems, and an ITM Power 670 kW electrolyser, at EMEC’s onshore site on the island of Eday.Multiple energy flow scenarios were trialed. During high generation periods, power from the O2 was used to charge the battery system, supply electricity directly to the electrolyser and export power to the grid. When tidal generation was low, the battery system discharged power to the electrolyser to keep the electrolyser operating.This approach effectively smoothed out the cyclical nature of tidal energy, enabling on-demand electricity to power
PacWave Inks ‘Historic’ US Wave Power Purchase Deal
PacWave, administered by Oregon State University, has signed a power purchase agreement with the Bonneville Power Administration (BPA), paving the way for wave-generated electricity to be supplied to the U.S. grid for the first time.The agreement marks a major step for CalWave, which will deploy its xWave technology at the PacWave test site. The company said the project represents its move from research and development into commercial operations after previously exporting power only to a microgrid at the Scripps Institution of Oceanography during a 2021–22 open-ocean deployment.The five-year
Dieseko, CorPower Joint Project to Streamline Offshore Anchor Installations
funding, the project will combine Dieseko’s vibro hammer technology with CorPower’s next-generation anchor concepts.The work supports future deployment of CorPower’s wave energy arrays located within and around offshore wind farms, where anchors provide the foundation for large-scale electricity generation from waves.The collaboration focuses on further optimization of CorPower’s UMACK anchor, a universal offshore anchor system. Integration of Dieseko’s vibratory installation methods aims to streamline deployment, reduce environmental impact and lower the Levelized Cost of
Jasmund Substation Nears Baltic Sea Installation After Topside and Jacket Load-Out
which holds the full EPCIC scope covering engineering, procurement, construction, installation and commissioning. OSS Jasmund is the first of three offshore substations the consortium is delivering for 50Hertz.Once operational, the Jasmund substation will have a capacity of 300 MW, supplying renewable electricity to around 260,000 households. It will serve as the grid connection point for the Windanker offshore wind farm, located northeast of Germany’s island of Rügen.Earlier this year, the HSI joint venture completed the rollout of the topside and lifted transformers at the Stormpolder yard
NKT Completes Export Cable Repair at Beatrice Offshore Wind Farm
, which was hired for the repair job following an unplanned transmission outage that occurred in April 2025 on one of two of Beatrice’s Transmission Capital Partner (TCP) owned export cables.The malfunction reduced the site’s export capacity by 50%, affecting the transmission of renewable electricity for around 450,000 U.K. households.The cable, which was not manufactured by NKT, was repaired using NKT’s adaptive rigid sea joint (ARSJ). Central to the swift turnkey repair were two of those joints, which were mobilized from NKT’s stock within days.The joints are designed to work
Study: Allseas SMR Tech Seen as Key Maritime, Industry Decarbonization Tool
energy at the point of use could support the Dutch grid by easing congestion, unlocking €46 billion in additional economic activity and avoiding as much as €14 billion in high-voltage grid investments out of the €121 billion planned through 2050.The reactor is designed to deliver clean electricity at prices competitive with fossil and renewable sources, while supplying industrial heat of up to 650°C at lower cost than gas turbines or renewable heat technologies. The report said these features significantly improve the energy security of Dutch industry.Allseas’ SMR could enable
EU-Backed Project Deploys OTEC Demonstration Unit off Canary Islands
such as the historic Mini-OTEC and OTEC-1 projects, deployed in the late 1970s and early 1980s off Keahole Point in Hawaii, which used a U.S. Navy barge and a converted World War II T2 tanker, respectively.OTEC is a renewable technology that harnesses the ocean’s thermal gradient to generate electricity. Warm surface seawater is used to vaporise a working fluid, driving a turbine to produce energy, while cold deep-sea water condenses the fluid, creating a continuous cycle.This phase involved deploying the platform’s cylindrical hull at the Oceanic Platform of the Canary Islands (PLOCAN)
Fugro Concludes Site Investigations for TenneT’s Offshore Grid Links
for transmission system operator (TSO) TenneT Germany, to support the development of the LanWin1 and LanWin2 offshore grid connection projects.These projects are part of TenneT Germany’s 2 GW program, a major initiative that aims to connect at least 14 offshore connection systems to the onshore electricity grid, delivering clean energy to up to 35 million European households.The LanWin2 cable route required a range of onshore and nearshore investigation activities to support project development. Fugro’s new GroundIQ service enabled low-impact geophysical surveys, including electrical resistivity
Climate Tipping Points are Being Crossed, Scientists Warn
, the biosphere,” said environmental scientist Tim Lenton at the University of Exeter, who is the lead author of the report.SOME POSITIVE SIGNSLenton noted positive signs when it came to phasing out the fossil fuels most responsible for climate change. Renewables, for example, accounted for more electricity generation than coal this year for the first time, according to data from the nonprofit think tank Ember.“Nobody wants to be just traumatized and disempowered,” Lenton said. “We still have some agency.”The scientists implored countries at November's COP30 to work toward
