The Smart Green Shipping Alliance, SGSA, is an award winning, collaboration of SMEs, large corporations pioneering maritime renewables.  


 Renewable energy improves shipping's economic resilience. It can fundamentally change the economic dynamics of ships' performance. Once technology to harness it is installed significant amounts of propulsion is free, abundant and exclusively available to that particular ship. This allows bunker buyers to hedge commodity fuel risks, improve predictability of cash-flow whilst reduced fuel consumption increases operational flexibility.  

The cost of renewables is tethered only to the cost of technology, and we can see from the evolution of renewables in power generation how rapidly those costs can fall. Commodity fuels, be they fossil, bio or synthetic, are inextricably linked to inherently volatile markets. 

For shipping the renewable energy of choice, of course, is wind. Over thousands of years humankind has facilitated global trade through wind powered ships.

Wind power made our world

We have three strands of interconnected work:

FAST tech harnesses the wind

TRADEWIND values the wind

RE:SURGE monetises the wind

A 21st century sailing ship will be as different from the Cutty Sark as a Model T Ford is to a Tesla, or a 3MW offshore wind turbine is to a Dutch windmill.

Modern ships equipped to harness infinitely available wind that works in conjunction with super-efficient engines can meet the stringent schedules demanded by modern shippers.

The Paris Agreement means that new ships operating today, which have a typical 30-year lifetime, need to work in a zero-emission world.

The International Maritime Organisation commits to reducing GHG emissions by 50% by 2050


Shipping is a complex and interconnected system. We collaborate across the shipping world. We work with ship owners, operators, shipping law and insurers, financiers and, most critically, end-users – the people who own the cargo. They give us the parameters around which to design - the size of ship, it’s speed, routes, loading and discharge ports.

The European Climate Foundation and the UCL shipping consultancy UMAS enable deep understanding of the existing maritime system. At the technology development end, SGSA works with world-leading racing yacht designers at Humphreys Yacht Design and Wolfson Unit at Southampton University combining their expertise with commercial naval architects and marine engineers at world-leading ship yards. We work with Lloyds Register to ensure the new designs are classed swiftly.

Beyond that we weave in knowledge from aviation, defence, Formula One and land based renewable energy systems.
