New version of the Wärtsilä 31DF engine reduces methane emissions

Technology group Wärtsilä has introduced a new ultra-low emissions version of its already efficient Wärtsilä 31DF engine. When operating on LNG, this new version can further reduce methane emissions on a 50% load point by up to 56% and nitrogen oxide (NOx) by up to 86%. On a weighted average, this new technology can reduce

New technology for converting CO2 to CO holds potential

A new energy-efficient carbon dioxide capture technology that converts carbon dioxide to carbon monoxide under electro catalytic conditions under ambient temperatures in the presence of water has been developed with potential for application in the steel sector. In efforts to support India’s goal for net-zero emissions by 2070, the DST-supported National Centre of Excellence in

DNV and AL Group to cooperate on CCS feasibility study

Classification society DNV has entered into a Joint Development Project (JDP) with AL Group and its Singapore company Asiatic Lloyd Maritime LLP to explore the feasibility of carbon capture and storage (CCS) on board AL’s 7,100TEU containership and Kamsarmax bulk carrier newbuildings. Under the JDP, DNV will cooperate with AL on a techno economic study

Engineers develop process to make fuel from carbon dioxide

The search is on worldwide to find ways to extract carbon dioxide from the air or from power plant exhaust and then make it into something useful. One of the more promising ideas is to make it into a stable fuel that can replace fossil fuels in some applications. But most such conversion processes have

Wärtsilä begins strategic review of its energy storage, optimisation business

Wärtsilä Board of Directors has decided to initiate a strategic review of its Energy Storage and Optimisation (ES&O) business. The strategic review aims to assess options that would accelerate the profitable growth of the ES&O business in a way that benefits its customers, employees, and the value creation for Wärtsilä shareholders. As part of this

Carbon budget for 1.5°C will run out in six years

If humanity wants to have a 50-50 chance of limiting global warming to 1.5°C, we can only emit 250 another gigatonnes (billion metric tonnes) of CO₂. This effectively gives the world just six years to get to net zero, according to calculations in new paper published in Nature Climate Change. The global level of emissions

Black Sea’s green hydrogen holds promise as green fuel

Hydrogen sulfide, a toxic chemical that exists in significant quantities in the depths of the Black Sea, has long been considered a risk to the local marine ecosystem. But some experts believe it could be used as a source of clean energy equivalent to over 850 million tons of oil, with added ecological benefits. With

Wallem Group makes strides in decarbonisation

Wallem Group, a leading global maritime partner, is proud to have welcomed two dual fuel vessels, Angleviken and Askviken, into management in the last few months. The two LR2 tankers, delivered by Guangzhou Shipyard International, demonstrate Wallem’s commitment to building its expertise in managing and operating the vessels of the future and being a partner

Boskalis signs for methanol-ready dredger

Boskalis has become the latest in a long line of shipowners to sign up for methanol as an alternative fuel for one of its newbuilds. The Dutch dredging and marine engineering firm has contracted compatriot shipbuilder Royal IHC for the construction of methanol-ready and one of the largest trailing suction hopper dredgers in its fleet.

Need to fast track carbon capture to achieve for netzero

To achieve global net zero goals by 2050, the world has to urgently fast track capturing 7 billion tonnes of carbon dioxide per year, according to Wood Mackenzie research. According to their analysis, the current pace of carbon removal is on course to reach only 2 billion tonnes of CO2 by 2050 (base case scenario).
