Swedish Wave Energy Tech Developer Attracts Funding

(WEC) that extracts energy from the vertical motion (heave) of the waves. The innovative elongated rectangular float is designed in a way that resembles the shape of a wave.Presently the development is at Technology Readiness Level 5/6 , the unit having been prototype tested in both wave tank and offshore in its basic version, scale 1:5. The funding will provide means for further fine-tuning of the float and PTO/machinery, to increase effectiveness and prolong lifetime for various components.According to the technology description on the European Commission's website, NoviOcean's Power Take-Off

which are already installed for sensors are adequate to ensure the reliable operation of the actuators. Up until now, Bosch Rexroth says, the operators of process systems have mainly relied on hydraulic cylinders in order to open and close subsea valves with a quarter turn and a defined force. With offshore installations, for example for oil and gas production, these cylinders are supplied by a  central hydraulic power unit with hydraulic pipes several kilometers in length. This solution uses a great deal of energy in order to compensate for the cumulated losses and it cannot control the movement

Environmental Groups Call on Norway to Stop Deep-sea Mining Plans

Six environmental organizations, including the World Wildlife Fund and Greenpeace, on Monday, called on Norway to stop plans to open ocean areas for deep-sea mining.The government in January launched a process to open areas on its extended continental shelf for exploring and producing minerals from the ocean floor, with plans to issue the first licenses as early as 2023."Minerals and metals for the green shift should be obtained from consumption reduction and better reuse on land, not from the depths of the sea where brutal mining can do irreparable damage to nature," the environmentalists

Fugro, MMT Tapped for Seabed Mapping Work at Danish Wind Energy Hub in North Sea

Dutch offshore survey firm Fugro and Sweden's MMT have won contracts with the Danish grid operator Energinet, to carry out seabed surveys for the Danish Energy Island project in the North Sea.The contracts follow an announcement by the Danish authorities in February that the country would build the first of its kind wind energy hub in the North Sea that promises to produce yet unseen amounts of green electricity, in what has been described as the largest construction project in Danish history.The energy hub - an artificial island - will serve as an offshore power plant gathering and distributing

“Since plans for our OceanVision project started in 2018, we have been preparing our industry leading Synthetic Aperture Sonar and 3D underwater laser scanning technologies to be used in a Robotics/Data as a Service (RDaaS) business model as opposed to a product only strategy," said Karl Kenny, Kraken President and CEO, in discussing the Letter of Intent to acquire PanGeo Subsea.

, it is notable that both wave and tidal technologies have taken major steps forward in recent years. Both are progressing towards commercial readiness – as standalone projects, but also as part of hybrid renewable technology deployments, co-located with shared infrastructure. For example, hybrid offshore floating wind and wave generation could, and should, be a game-changer for our shared ambition of a reliable and flexible electricity network in a carbon-neutral world.”Rémi Gruet, CEO of Ocean Energy Europe added: “It is a great pleasure to welcome Simon and Patrik as Co-Presidents

New Tech Deployed to Study Harmful Algal Blooms

A new research project aims to evaluate the potential efficacy of ultrasonic technology to mitigate harmful algal blooms (HABs) on Lake Agawam, village of Southampton.HABs are a growing environmental problem, affecting all parts of the world. Excessive nutrient pollution entering water bodies, especially phosphorus and nitrogen, drive the growth and spread of harmful algal blooms. Besides unpleasant tastes and odors, excessive HABs can seriously harm humans, pets, and aquatic organisms, and degrade water quality. Additionally, they can disrupt water treatment processes by clogging filters and pipes.

climate envoy, and former Environmental Protection Agency (EPA) Administrator Gina McCarthy was designated as the domestic climate czar. They have their work cut out for them, as the goal of simply meeting the present Paris Climate Agreement goals may not reduce GHG emissions to the required levels.Offshore wind will be a critical part of reaching the new domestic and international climate goals. President Biden recognizes this fact in the EO by promising to double offshore wind by 2030. Developers also recognize the connection by touting reductions in GHG emissions with each project.  Right now
