Lloyd's Register awards the first Technology Qualification Certificate for ocean energy to WaveRoller®
Innovative renewable technology gives confidence to a new form of approved ocean energy power generation.
Using Silicon in Lithium Ion Batteries to Increase Capacity
A key attribute of silicon in lithium ion batteries (LIB) is the higher capacity that Si can offer which leads to greater electric vehicle driving range or longer operating consumer electronics.

European offshore wind developers join forces with the Carbon Trust to slash costs of offshore wind
Nine of the largest offshore wind developers in Europe: DONG Energy, EnBW, E.ON, Iberdrola, RWE, SSE, Statkraft, Statoil and Vattenfall have signed up to the programme. Over the next four years the developers will collectively invest at least £6.4 million, boosted by a further £1.5 million from the Scottish Government, to bring new innovations to market that will help to ensure that the typical cost of offshore wind is below £100 per MWh by 2020.
Why Every Rooftop Solar System Needs Energy Storage
John Petersen for Investor Intel: Rooftop solar is an odd duck. A consumer buys an expensive capital asset with the expectation that he’ll recover his investment through lower electric bills. As a matter of metaphysics, he’s decided to go into the power business with the primary goal of satisfying the most important and discriminating customer on the planet. The value proposition he currently offers his local electric utility is:
I’ll buy less electricity from you because of my solar panels, but I need you on standby 24/7 to supply my nighttime needs and fill any weather related power production gaps;
Since my solar panels will frequently produce more power than I need, I want you to give me credit for any excess power production, let me draw equivalent power from you when I need it, and structure it all as a tax free swap;
You can, of course, bill me for any difference between what I deliver and what I take;
I’ll have no duty to buy a fixed amount of power from you or deliver a fixed amount of power to you, but you must supply whatever I need and take whatever I don’t need; and
You will be required to pay all of the costs associated with weather related production gaps and pass those costs through to your other customers.

Scripps Vessel Proves Viability of Renewable Fuel on 14,400-Mile Voyage
Chris Jennewein for Times of San Diego: A Scripps Institution of Oceanography research vessel has demonstrated the viability of renewable fuel by traveling 14,400 nautical miles over a 16-month period on renewable diesel.
The R/V Robert Gordon Sproul used a hydrogenation-derived renewable fuel called NEXBTL Renewable Diesel developed by Neste Oil in Finland. The experiment began in September 2014 and ran through December 2015, during which time the vessel used a total of 52,500 gallons.
“Part of the Scripps mission is to protect the environment, and one of the most significant changes that we could make in our ship operations involved moving toward the use of cleaner, renewable fuels,” said Scripps Associate Director Bruce Appelgate. “As scientists, we know we need to develop sustainable means of powering our ships to address pollution concerns as well as to mitigate future increases in fossil fuel costs.”
Renewable biofuel is nearly carbon-neutral and produces cleaner emissions, thus decreasing greenhouse gas emissions and improving air quality relative to fuels derived from petroleum. Cont'd...
