This $30 Million Yacht Is Very Luxurious + Has Hybrid Engines


New yachts are coming out of shipyards all the time. But few have inspired as much lust in recent memory as the the Columbus Sport 130-ft. Hybrid.
The Columbus was constructed by Palumbo Shipyards of Italy, with the intention is to have as small an impact on the environment as possible.
On the outside, this yacht is beautiful.
But the real innovations are within, including a very unique marine hybrid system.
[An earlier version of this story was written by Travis Okulski.]

Under the sleek exterior, the Columbus Hybrid has some clever tech.

 

So how is a hybrid system achieved in a ship? It cannot utilise regenerative braking like in a car.

 

Instead, hybrid means something a little different here. The ship can turn off its main engines and run solely on generators.

 

Yes, it moves much slower, but the constant RPM of the generators also consumes vastly less fuel than the main engines.

 

The generators power electric motors, so navigation becomes virtually silent.

 

While cruising, the some power from the big engines is stored to power the electric motors. Hence the hybrid system.

 

Along with the hybrid system, there is also a heavy emphasis on the use of aluminium in the construction.

 

Aluminium reduces the weight of the ship, which should then reduce consumption even further.

 

The cruising range of 5,000 nautical miles is nothing to sneeze at.

 

She can fit eight people in three staterooms and a master suite. There is also room for crew and a captain.

 

Decking is teak, and the large windows let in the light and scenery better than other yachts her size.

 

It's a very impressive yacht.

 

These yachts are out of this world...

The Battery Revolution: A Technology Disruption, Economics and Grid Level Application Discussion with Eos Energy Storage

Recent advancements in energy storage technology could finally make renewables, such as wind and solar, truly viable economic alternatives to fossil fuels when it comes to generating power. The ability to store power bridges the reliability gaps that occur with renewables, when, on any given day, the sun just doesn’t shine bright enough or the wind doesn’t blow hard enough to feed the hungry power grid.

So what is this amazing new technology? It’s batteries – yes, batteries.



But we aren’t talking about any old battery here; rather, we are talking about super batteries with the ability to store megawatt-sized loads, enough to power entire neighborhoods or towns if need be. While you could theoretically achieve the same result by stringing together the type of batteries used to power your laptop or smartphone, the cost of doing so would be economically prohibitive. But entrepreneurial companies, such as Ambri and Eos Energy Storage, are pursuing thenext generation of battery technology, with the aim of bringing storage costs down significantly for utilities.
So what is considered to be a reasonable cost? The analysts at Citibank believe that battery storage costs should be between $230/kWh to $150/kWh to be financially attractive enough to see these mega-batteries deployed in large numbers across the power grid. They say the industry should reach this level somewhere around 2030 and expects 240GW of power storage capacity to be deployed by then, which would be worth around $400 billion.
The folks over at Eos believe the future is now. They say that they can produce battery systems with the ability to reach costs as low as $160/kWh – storing power efficiently and inexpensively. Investors are now clamoring to get a piece of Eos. On Monday, the company announced that it had secured $15 million in financing from AltEnergy LLC, an energy technology and infrastructure focused investment firm, with plans to raise an additional $10 million with strategic investors, for total gross proceeds of $25 million.
With such industry interest in battery technology, I sat down with Philippe Bouchard, vice president of business development at Eos, to discuss grid-level storage and how technology is fuelling this new revolution in batteries. The following interview has been edited and condensed for publication.
When will batteries make their mark on the power industry? Do we have to wait ten or fifteen years to see any change?
What most people don’t realize is that batteries are already transforming the energy industry.

Just delivered Dorian VLGC has Clean Marine scrubber


Scrubber fitted in Dorian VLGC Corvette meets EPA wash water pH requirements
Scrubber fitted in Dorian VLGC Corvette meets EPA wash water pH requirements
JANUARY 15, 2015 — Dorian LPG Ltd. (NYSE: LPG), Stamford, CT, has taken delivery of the ECO VLGC (Very Large Gas Carrier) Corvette from shipbuilder Hyundai Heavy Industries.
Corvette is Dorian's third newbuilding delivery, will initially trade in the spot market and is the first of 15 deliveries that the company expects in 2015.
The ship is fitted with an exhaust gas cleaning system (EGCS) provided by Clean Marine AS, Lysaker, Norway.
Clean Marine says the measurements of exhaust gas emission and washwater criteria are well below the required limits stated in the MEPC guideline 184(59). This ensures compliance with the 0.1% sulfur limit in place in ECAs since January 1 this year. The vessel is also compliant with the stricter US EPA requirements of a pH above 6 in washwater, measured at the outlet.
The vessel's class society ABS, on behalf of the Bahamas Flag, issued a formal letter on January 8, 2015, confirming that the EGCS complies with "Scheme B – EGC System Approval, Survey and Certification Using Continuous Monitoring of SOx Emissions" of the IMO Resolution MEPC.184(59), 2009 Guidelines for Exhaust Gas Cleaning Systems.
The approved EGCS will enable the new Dorian LPG vessel to comply with current and future legislation relating to sufur emissions without switching to more expensive fuels.
Scrubber frontJohn Lycouris, Chief Executive Officer at Dorian LPG (USA) said:
"Dorian LPG is proud to be the first within the gas carrier market to install the Clean Marine EGCS and we look forward to trading the Corvette with the considerable technological and environmental advantages over similar vessels in the market.
"The hybrid EGCS delivered by Clean Marine to Dorian LPG vessel Corvette is an advanced solution compliant with the stricter washwater regulations in U.S. waters. We are confident that EGCS will play an important role in moving the shipping industry to comply with the new sulfur regulations in ECAs, as well as with the global cap in 2020 in a cost competitive manner.
"We are pleased with the cooperation with Clean Marine during planning, delivery and commissioning of the system, and the Class and Flag State approval process has been quick and efficient."
The Clean Marine system's integrated fan and gas recirculation technology allows one EGCS unit to simultaneously serve all combustion units, including the boilers – this Allstream feature is valuable and cost-efficient for vessels with many exhaust sources.
The Clean Marine system onboard the Corvette cleans both sulfur oxides (SOx) and particulate matter emissions from the main engine, three auxiliary engines, and one boiler. In total, a single Clean Marine EGCS unit will manage five exhaust sources and clean 140.000 kilograms exhaust per hour.
The system supplied to Dorian LPG is a hybrid type that can operate seamlessly in both Open Loop and in Closed Loop (zero discharge mode).

Torqeedo Introduces Deep Blue Hybrid



Torqeedo Introduces high-powered Deep Blue product line into hybrid solution line.
More than simply propulsion, this is the first fully integrated system that acts as an energy supply for both the hybrid drive and all AC/DC electrical loads on board. This solution can harness solar, wind, plug-in and regenerative power in the system's high-capacity batteries, keeping generator runtime to a minimum.

Ample and always available electrical power presents many benefits. Large house loads, such as air conditioning and cooking, can be met by batteries alone, leaving owners to enjoy all the comforts of home with no generator noise or exhaust to spoil the serenity. Work and service boats can run large tools, winches and test equipment directly off the high-capacity batteries. Environmental research and monitoring vessels can access sensitive areas and take measurements in clean, quiet, and undisturbed water conditions.

The modular nature of the components means Deep Blue Hybrid can be configured to match the specific requirements of each application. It is available as inboard, outboard or saildrive in the 40-160 hp power classes, and as a single or twins.

"Taking existing Deep Blue components and adding the utility of multiple charging sources was the next logical development for this powerful system," said Steve Trkla, president of Torqeedo, Inc. "Deep Blue Hybrid offers all the benefits of pure electric propulsion, including an unprecedented level of luxury and utility on board, while allowing for extended motoring. It is proving to be a very compelling option for cruising sailboats between 40 and 80', as well as professionally operated vessels."

Great Ships of 2014: The Hybrid-Powered Semper Fi


The MV Semper Fi  from the Netherlands is an innovative European inland waterway vessel measures 361 x 37.7 x 12.1 ft. (110 x 11.5 x 3.7 m).

In cooperation with MARIN, the Netherlands Maritime Research Institute in Wageningen, the Dutch shipping company Carpe Diem Shipping developed the novel concept of Semper Fi , which reportedly is the first inland vessel that can simultaneously be propelled by a diesel engine and an electric motor – a unique combination, and one that has confirmed a 10%  savings in energy consumption.

The hybrid drive is not the only sensation of the SEMPER FI project. Contra-rotating rudder propellers of VETH Propulsion type VZ-900A-CR-VHD, optimize the propulsion system. Propellers turning in opposite directions offer the decisive advantage in that they are not only made for improved maneuverability but also for extremely quiet operation – an important criteria for inland shipping.
The streamlined tunnel and the variability of the propeller, which can be controlled in all directions, adds to the system’s efficiency and versatility. Thanks to an integrated exhaust post-treatment system with 4 SCRT which include catalytic converters and soot filters, the SEMPER FI makes an additional contribution towards minimizing noxious emissions in inland shipping. In this process, the combustion gases are chemically cleaned using the so-called AdBlue method. A urea-based liquid is injected to bind the exhaust particulates and reduce the levels of nitrogen oxides. The AdBlue exhaust post-treatment system was supplied to the Semper Fi project by Veth Propulsion. The drive consist of: two Scania engines DI16 (512 kW / 1800 rpm), two E-engines (330 kW / 1800 rpm), two generating sets, Scania DI16 (634 kVA / 1800 rpm), two frequency converters for propulsion,one  frequency converter for bow thruster, one static converter to supply power to the board net, all supplied by VETH Propulsion.

Long May You Run - The next growth area in energy has nothing to do with oil, wind, or solar.

It’s batteries.

The notion of a giant utility regarding the melting and refreezing ice cubes as a realistic way of storing power would have seemed fanciful a few years ago—or even 12 months ago.
But next year, pursuant to a deal announced with utility Southern California Edison in November, Ice Energy will install 2,000 of its $10,000 Ice Bear units throughout Orange County, California. Erected adjacent to air conditioners, they use cheap electricity at night to turn tap water into a 450-pound ice block. During the day, refrigerant liquid is funneled from air conditioners through the Ice Bear, which cools it off and sends it back to the AC unit. The process saves an amount of electricity equivalent to taking a 5-ton commercial air conditioner offline for six hours. “We’re able to provide cooling without using any electricity other than using the fan,” says chief executive officer Mike Hopkins. (Watch a video on how the machines work below.) In all, the Ice Bears will provide SCE with the equivalent of 26 megawatts of storage capacity—enough to power several thousand homes for a few hours.  
This is monumental for Ice Energy, a 12-year-old company based in Santa Barbara. “Until two years ago, the market for energy storage was really a R&D market,” Hopkins says. Ice Energy had conducted some 36 pilot programs—money-losing, time-consuming one-offs. This order, for three times the number of units it has deployed in its entire history, will transform Ice Energy into a viable, profitable company.

The deal, part of a larger transaction in which SCE purchased a large amount of storage capacity for the first time, highlights an important new trend in the power business. Utility systems face constant stress. Demand (and therefore price) can swing wildly over the course of a 24-hour period—starting off low in the cool hours of the morning, peaking in midday when the sun is hottest, and then tapering off again at night. For much of the past century, utilities dealt with demand surges by keeping “peaking” plants idling on standby—firing up noisy coal- and gas-burning turbines when demand surges and powering them down when it abates. But that’s an expensive and fossil fuel–intensive proposition.
It makes far more sense to treat electricity the way people in the desert treat water: harvest it in times of plenty, store it in convenient cisterns, and then release it in times of need. That hasn’t been an option, largely because batteries and other storage systems were very expensive. But the market has shifted rapidly in the past couple of years—in part because the private sector is making huge investments and strides in new technologies and in part because California is using mandates to conjure an energy-storage industry into being.
In the fall of 2013, the California Public Utilities Commission issued a mandate that will force the three giant investor-owned utilities in the state to add 1.3 gigawatts of energy storage capacity by 2020—a huge amount. Utilities, whose profits are regulated already, often look askance at such efforts. “We always balk at any sort of minimum requirement,” says Colin Cushnie, vice president for energy procurement and management at Southern California Edison, which will be compelled to add some 580 megawatts of storage. “We like to let the market dictate.”
Aiming to get ahead of the mandate, SCE dipped its toes in the water last year, sending out a request for 50 megawatts of storage capacity in February 2014 as part of a larger offer to acquire new generating capacity. Some 1,800 bids from storage providers materialized, with many of them at surprisingly low costs. For utilities, a megawatt of storage can be equivalent to a megawatt of production. So SCE ended up acquiring 264 megawatts of storage capacity—more than five times the amount it had initially plotted.
In addition to Ice Energy, SCE contracted with three large companies that provide different varieties of battery-based storage: 100 megawatts of free-standing battery capacity from AES , 50 megawatts of battery systems that fit inside buildings fromAdvanced Microgrid Solutions, and another 85 megawatts of storage from Stem, which relies on advanced predictive analysis to dial building and battery usage up and down.
What’s so great about storage? After all, batteries and the Ice Bear don’t create new power. But they’re less noisy and intrusive than power plants—and provoke much less NIMBYism. The Ice Bears, for example, reside unobtrusively on roofs and in mechanical rooms near existing air-conditioning equipment. They start up more rapidly than power plants. And they make it easier for systems to manage the rising amount of intermittent energy coursing through the system—wind power that ebbs in calm periods and solar power that goes dark at night. “It allows you to store energy at times when it is either less expensive to generate, or is cleaner energy, and then discharge it when you have a need for it,” SCE’s Cushnie says.
This is good news for companies like Ice Energy, but also for other entities in the business of providing power. The Imperial Irrigation District, which provides electricity and water to California’s Imperial Valley, was ordered to increase its reliability as part of a settlement after a blackout in 2011. A few years ago, says Bruce Townsend, superintendent alternative energy at the Imperial Irrigation District, the only way to do so “would have been through fossil-fuel generation.” But instead of building a new gas-powered plant, IID is constructing a 20 megawatt battery.

First gas container for the LNG Hybrid Barge reaches the Port of Hamburg

In the coming year, the HUMMEL (bumblebee) LNG Hybrid Barge will enable Becker Marine Systems to supply low-emission power to cruise ships lying at port in Hamburg. The first container with LNG (Liquefied Natural Gas) fuel has now arrived in the Hanseatic City.
As part of the LNG Hybrid Barge’s testing programme, the first gas container for the marine fuel was delivered on Monday. “The testing of the gas engines at the Port of Hamburg is a first for both the classification society and participating authorities”, said Dirk Lehmann and Henning Kuhlmann, both Managing Directors of the global market leader for high-performance rudders.
The gas container from Shell Ganor, represented by Mr. Aksel Skjervheim, Marine LNG Business Development Manager, was formally delivered to Becker Marine Systems at the Blohm + Voss shipyard. The container with the marine fuel had previously made the journey from the Fluxys LNG Terminal in Zeebrugge, Belgium to Hamburg.
The barge works like a floating power plant and uses low-emission LNG (Liquefied Natural Gas) to supply environmentally-friendly energy to cruise ships. Compared to conventional marine diesel with 0.1% sulphur content, sulphur dioxides and soot are no longer emitted. Emissions of nitrogen oxides and carbon dioxide are also significantly reduced.
The LNG Hybrid Barge, developed by Becker Marine Systems and recently christened the
HUMMEL (bumblebee), will officially commence operations at the Port of Hamburg at the beginning of the cruise season in spring 2015.

Carnival Corporation's AIDA Cruises: Dr. Monika Griefahn Christened World’s First LNG Hybrid Barge in Hamburg


The world’s first LNG hybrid barge of Becker Marine Systems was christened with the name “Hummel” on October 18, 2014, at Grasbrook Quay in HafenCity Hamburg. The godmother of the inaugural event for the floating LNG power plant for environmentally friendly energy supply of cruise ships was Dr. Monika Griefahn, Chief Sustainability Officer at AIDA Cruises. The co-founder of Greenpeace Germany and former Minister of Environment of Lower Saxony has been involved in sustainability and environmental protection for more than 30 years.

“With this pilot project, Becker Marine Systems and AIDA Cruises are together setting an example for environmental and climate protection, not only for the city of Hamburg but also for the entire maritime industry,” said AIDA President Michael Ungerer. “With the LNG hybrid barge, we have again demonstrated that environmental protection and economic interests are not a contradiction for us.”

Thanks to the use of the floating LNG power plant, emissions and particle discharge will be significantly reduced. Compared to the use of conventional marine diesel with 0.1 percent sulfur content, no sulfur oxides and no soot particles are emitted. Nitrogen oxide emissions will be reduced by up to 80 percent and carbon dioxide emissions by 30 percent.
As part of the inaugural event, the plug connection between the LNG hybrid barge and AIDAsol was successfully tested. With the start of the new cruise season in the spring of 2015, it is planned to supply the AIDAsol for the first time with electricity produced from liquefied natural gas (LNG) while it is berthed in the port of Hamburg.

All ships of the AIDA fleet which were put into service in 2007 or later are already prepared for the use of shore power. Since 2007 the company has voluntarily used only marine diesel with 0.1 percent sulfur content for the production of energy on board its fleet in the Port of Hamburg. This has been required by law for all seagoing vessels in European ports only since 2010.

In the summer of 2013, the company adopted an additional investment program in the amount of 100 million euros for the use of state-of-the-art environmental technologies. The core of the program is a comprehensive filter system for reducing exhaust gas emissions. With this unprecedented technology for exhaust treatment, emissions of soot particles, nitrogen oxides, and sulfur oxides will be reduced by 90 to 99 percent for the first time. It is not just the two new AIDA ships that will be put into service in 2015 and 2016 that will be equipped with this technology developed within the Carnival Group. The ships of the existing fleet will also be gradually retrofitted with this filter system.
In the spring of 2016, the first ship of the new AIDA generation, AIDAprima, will be moored for the first time in its future home port of Hamburg. 

AIDAprima is the first cruise ship with a shore power connection, a comprehensive system for exhaust gas aftertreatment, and a dual fuel engine. This can be operated with conventional fuel or LNG, depending on availability.
As a cruise line and tour operator, AIDA Cruises operates and markets one of the world’s most state-of-the-art and environmentally friendly fleets, currently comprising 10 cruise ships. The ships are operated in compliance with the highest international quality, environmental, and safety standards. The AIDA fleet will be expanded to 12 ships by 2016. Since 2007 the company has published its annual Sustainability Report, which is based on the international GRI standard. More information is available here.
