To some, the word 'nuclear' conjures up images of mushroom clouds and Chernobyl. So a nuclear battery may sound downright dangerous. But, in fact, nuclear batteries have been safely powering pace-makers, satellites and underwater systems for years. They boast an extremely long life and high energy density compared to typical batteries. However, they are also large and heavy: or at least they were.
Researchers at University of Missouri (MU) are working on a smaller, lighter model. Jae Kwon and his research team are developing a battery that is currently the size and thickness of a penny. However, the battery's small size is not the only innovation; it also utilizes a liquid semiconductor rather than a solid one.
"The critical part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure of the solid semiconductor," Kwon said. "By using a liquid semiconductor, we believe we can minimize that problem."
Working in collaboration with J. David Robertson, a chemistry professor and the associate director of the MU Research Reactor, Kwon is working to build and test the battery at the MU research facility. He hopes to increase the battery's power while continuing to shrink its size. In fact, Kwon said the battery could eventually be thinner than the thickness of human hair.

Swire Energy Services' acquisition of ALL NRG marks its second wind-focused deal this year, as Vestas secures 58MW order for wind project in Australia

Swire Energy Services (SES) has bought Danish wind services provider ALL NRG for an undisclosed fee, with SES becoming sole owner of ALL NRG  wind and solar division. 

The company currently operates across wind markets in Europe and Asia. ALL NRG was established in 2014 by Nordic private equity firm, Via Equity, by the acquisition of four prominent energy-related companies: APRO Wind, VB Enterprise A/S, Q-Star Energy A/S and WTG Partners A/S.  

Manfred Vonlanthen, CEO of Swire Energy Services, said: “This acquisition, alongside the investment of BladeInsight in June of this year, positions Swire Energy Services firmly within the wind industry. ALL NRG has an impressive track record and is a trusted service provider, with access to over 600 highly qualified technicians. 

“With this competence, in combination with our global reach and our long-term experience operating safely in the offshore environment, we will be able to service OEMs, operators, and owners with a full spectrum of specialist services for wind projects globally. We welcome Michael Thatt and his team and look forward to developing our service offering together in line with our strategic vision for wind services within SES.” 

Via Equity is happy to see the ALL NRG services continuing under new ownership and we are certain SES will have great opportunities to excel in the very promising market for wind and solar, added Peter Thorlund Haahr, partner at Via Equity. 

This is the second wind focused acquisition for Swire Energy Services this year, and forms part of the company’s long-term strategic objective to grow its renewable energy sector offering to support customers through the energy transition.  

ALL NRG will be rebranded Swire Energy Services, which will roll out across the organisation from August 3. 

Vestas wins 58 MW wind project order in Australia

In partnership with Global Power Generation, a subsidiary of the multinational power company Naturgy Group, Vestas has secured a 58MW deal for Crookwell 3 Wind Farm in New South Wales, Australia. The project will feature 16 V126-3.45 MW wind turbines in 3.6 MW operating mode which Vestas will supply and install.

Upon completion, Vestas will also deliver a 15-year Active Output Management 5000 (AOM 5000) service agreement. This agreement will optimise energy production while also providing long-term business case certainty.

“As the largest installer and maintainer of wind turbines, both globally and nationally, we are pleased that customers like Global Power Generation (Naturgy Group) continue to choose our leading technology, market experience and broad service solutions”, said Purvin Patel, President of Vestas Asia Pacific.

“Global Power Generation (Naturgy Group) is a globally valued customer to Vestas”, said Peter Cowling, Head of Vestas Australia and New Zealand. “We look forward to championing their ambitious vision of sustainability in Australia through the successful delivery of Crookwell 3 Wind Farm, and our remaining projects which are currently in progress. 

Once again, Global Power Generation is very pleased to partner with Vestas as OEM and long-term maintenance provider for Crookwell 3 Wind Farm, added Pedro Serrano, Chief Business Development Officer, Global Power Generation (Naturgy Group). Delivery of the wind turbines is expected to occur in the second quarter of 2022, with commissioning to commence in Q4 2022.

Last month leading CEOs from the global wind industry united to call on G20 members to show leadership in the climate crisis by raising national ambitions and urgently laying out concrete plans for increased wind energy production to replace fossil fuels (click here).
