More incentives needed to make green switch

Green technologies need the right incentives in place to be adopted on a wider scale making the case easier for operators to switch.

That was the key message of the Clean Technologies segment of TECH TOC at TOC Europe 2018 where talk of environmental regulations underpinned discussion.

Satu Kaivonen, environmental specialist at Konecranes, opened the segment by highlighting the benefits of the circular economy, which promotes selling value instead of material and functions on recycling, remanufacture, rental and leasing, reusing and maintenance and repair.

Speaking about how ports can support the circular economy, she said: “Working together as an industry, we can enable more efficient use of raw materials, increase energy efficiency and create value for our customers.”

However, she stressed any model used has to have the right incentives in place to make both economic and financial sense.

Electrification efficiency

Chris Pretorius, head of BD energy management at Siemens talked about the cost savings and energy efficiency that can be achieved with electrification.

He noted that a solution to the high cost of implementing and utilising shore power could be to use a self-contained mobile unit, using Siemens' SIHARBOR solution as an example.

He explained how to use hydrogen as an energy integrator to generate additional revenue streams based on refuelling stations, conversion of excess energy from Wind & PV parks, onsite local industry production and injection into local natural gas networks.

Balance is important

Looking at the power infrastructure of ports, Roberto Bernacchi, global product manager - shore-to-ship power & smart ports at ABB reinforced the message that “sustainable development in ports relies of achieving the optimum balance of costs and benefits,” adding that each project must be individually assessed to ensure CAPEX/OPEX optimisation.

Other companies participating in the segment included CVS Ferrari, CRESS Systems, Hyster, Volvo Penta and Liebherr.
