Solar Boat with Electric Engine Makes 7,200-Mile Trip

A custom vessel designed by Capt. Jim Greer completed a 7,200-mile voyage running solely on solar panels, batteries and an all-electric propulsion system.

The vessel, RA, is a 48-ft. trimaran named for the sun god of ancient Egypt. It is propelled by a Torqeedo Cruise 10.0 kW motor and a pair of smaller Cruise 4.0 kW outboards. The electric motors draw power from two banks of batteries—one with four 12V AGM batteries in a 48V configuration, and the other with eight of the same batteries also in a 48V configuration. The batteries are recharged from the array of 20 245-W solar panels on the roof of the cabin.

The Great Loop voyage took RA from Florida up the East Coast, through the Great Lakes, down the Mississippi and across the Gulf of Mexico, finishing the trip at Sand Bar Island, Florida. It was completed in two segments with a break in Waterford, New York. Greer said this was the first time a solar-powered all-electric boat has completed the Great Loop.

“No doubt about it, electric is the wave of the future.” — Capt. Jim Greer

Greer estimates that the cost of fuel for a similar size boat would have been at least $10,000 for the Great Loop.

“Not only did we save money on fuel, we achieved zero emissions, demonstrating that boating doesn’t have to pollute the air or water with emissions from a combustion engine.”

Carbon Risks to Ship Financiers Detailed in Executive Report

An executive report released this month details the complicated relationship of ship-financing banks, their risk premiums and lending portfolios with energy-efficient ship design, split incentives for owners and the monitoring, reporting and verification (MRV) requirements from the IMO and the EU.

The report was published by the Carbon Pricing Leadership Coalition (CPLC), an organization geared toward tracking carbon effects on prices. CPLC is governed by leaders from around the world in government, business and civil organizations. The World Bank serves as the CPLC secretariat.



Wind and Solar System Offers Promise for Sustainable Eco Ships

The Aquarius Eco Ship uses the Aquarius MRE integrated wind and solar power system developed by Eco Marine Power to create a more sustainable shipping vessel with reduced fuel consumption and lower emissions. The Eco Ship concept includes an advanced integrated system of rigid sails, marine-grade solar panels, energy storage modules and marine computers that automatically position the rigid sails to make use of current weather conditions.

The concept can be applied to most ship sizes and types including bulkers, oil tankers, survey ships, passenger ferries, cruise ships, Ro-Ro ships, car carriers and unmanned surface vessels. Aquarius Eco Ship can also be fitted with other fuel saving measures such as an advanced electrical propulsion system, air lubrication, an optimized hull design and waste heat recovery technologies. Fuel cell technology could also be incorporated into the design.

Webinar Today on DoD Funding Opportunity for Environmental Science, Technology R&D

The Department of Defense’s (DoD) Strategic Environmental Research and Development Program (SERDP) is seeking to fund environmental research and development proposals.

SERDP Acting Executive Director Dr. Herb Nelson and Deputy Director Dr. Andrea Leeson will host an informational webinar about the funding opportunity today, September 25, 2017, from 1:30 – 2:30 p.m. ET. 

SERDP is DoD’s environmental science and technology program, planned and executed in partnership with DOE and EPA with participation by numerous other organizations.  The program invests across the broad spectrum of basic and applied research, as well as advanced development.

The SERDP program requests proposals is in the following areas:

Environmental Restoration — Research and technologies for the
characterization, risk assessment, remediation, and management of
contaminants in soil, sediments and water.

Resource Conservation and Resiliency — Research that advances DoD’s
management of its installation infrastructure in a sustainable way.

Weapons Systems and Platforms — Research and technologies to reduce,
control and understand the sources of waste and emissions in the
manufacturing, maintenance and use of weapons systems and platforms.

Proposals are due October 19, 2017 by 2:00 p.m. ET.
