viability

Three major offshore wind projects in New York have been cancelled because of the unavailability of technology critical to the projects. The projects were part of NYSERDA‘s third offshore wind solicitation and were provisionally awarded last October. The projects, which totaled more than 4 GW of clean energy, were supposed to begin commercial operation in 2030.

The projects were Attentive Energy One, intended to benefit historically marginalized communities in New York City; Community Offshore Wind, a farm located 64 miles offshore that would power 500,000 homes; and Excelsior Wind, which would have powered 700,000 homes.

What happened is GE Vernova – a GE spinoff energy equipment company – decided to no longer develop its new 18 MW Haliade-X wind turbines and instead concentrate on its lower-powered models which already have ample demand. The material changes to the three projects using the turbines made them no longer viable and the developers and their partners could no longer come to terms. As a result, NYSERDA decided to not go forward with the awards.

While this represents a significant blow to the offshore wind industry and to New York’s renewable energy goals, NYSERDA said that it remains committed to advancing New York’s offshore wind industry and expects to announce new plans and additional projects in the near future.

In the bigger picture, 2023 was a record year for wind power; the world installed 117 gigawatts of new wind capacity. This year has seen the first major offshore wind farms come online in the US.

A new bio-composite material made from date palm fiber biomass could be used to produce sustainable, lightweight and low-cost parts for the automobile and marine industries.

A team of researchers from the UK has developed a date palm fiber polycaprolactone composite that is completely biodegradable, renewable,sustainable and recyclable, in contrast to synthetic composite materials reinforced by glass and carbon fibers. The team tested the mechanical properties of the material and found that it achieved better low-velocity impact resistance than traditional man-made composites.

The idea would be to use the material in non-structural auto parts such as car bumpers and door linings. The result would be to reduce the weight of vehicles, contributing to less fuel consumption and lower emissions. The new material can be produced using less energy than glass and carbon fibers and is biodegradable and therefore easier to recycle.

Date palm fibers are one of the most available natural fibers in many parts of the world. The trees produce a large quantity of agricultural waste, which is mostly burned or land-filled,causing serious environmental problems.

Convincing industry to use a new class of materials such as natural-fiber reinforced composites is challenging. First it is necessary to obtain consistent,reliable properties from the material. Then the industries need to work closely with the developers to test the materials and convince themselves of the viability of using them. The team, led by researchers at the University of Portsmouth, has been working with industry to test the viability of parts made from a variety of other sustainable materials as well including flax, hemp, and jute. Someday, our cars may have bumpers made from agricultural waste.
