Making the Impossible Possible

This blog sketches a vision on how to convert the largest crane vessel in the world - Sleipnir - owned by Heerema Marine Contractors, to a zero-emission vessel. Several promising carbon reduction measures are combined which are technically viable and based on matured technology, although scaling of existing technologies and cooperation with key partners is required. Key technologies include electrification, on-board batteries, solar panels, synthetic fuels, carbon capture and storage and possibly hydrogen.

Tesla Battery Day in 16 minutes

Elon Musk made some big announcements. The company is planning to get rid of Cobalt in their batteries and to manufacture its own “tabless” batteries, called 4860 cells. This type of battery is six times more powerful, and the range will be increased by 16 percent. The new battery technology will make a $25,000 Tesla car a reality.

Recycling vehicle batteries

Helen Czerski went to Wendeburg in Germany to see if it really is possible to recycle the materials in vehicle batteries. She shows how this new and rapidly growing industry is developing and coming up with some interesting results, with lithium-iron batteries being economically recycled up to 70% (91% including graphite). Please send this to all the people you know who say 'what about when we throw all these fancy batteries into landfill.

Tesla Virtual Power Plant: A Technical Guide

Colin Breck and Percy Link explore the evolution of Tesla's Virtual Power Plant (VPP) architecture. A VPP is a network of distributed energy-resources (often solar, wind, batteries) that are aggregated to provide smarter and more flexible power generation, distribution, and availability. Tesla's VPP consists of vertically integrated hardware and software, including both cloud and edge computing.

The Trouble with Cobalt by Joe Scott

Electric cars have a dark secret - cobalt. The element that is in almost all lithium-ion batteries is often considered a conflict mineral because half of all cobalt reserves are found in the Democratic Republic of Congo, a troubled region with over a century of instability. But is it as bad as the anti-EV crowd has led us to believe? What's the reality of the situation, and what are some of the solutions?

Transocean Spitsbergen goes Hybrid

In April 2019, the Transocean Spitsbergen successfully and sagely installed an electric Energy Storage System (ESS) of 5.6 [MW] on-board. This allowed the semi-submersible drillship to run in hybrid mode during DP3, reducing fuel consumption by about 15%. Economic incentives were provided in the fuel-clause and by the Norwegian NOx Fund.
