St. George’s, Grenada, Thursday May 31st, 2018. On Tuesday May 29th, 2018, Grenada became the 37th country among the 197 Parties to the Montreal to ratify the historic Kigali Amendment to the Montreal Protocol on sunbstances that deplete the ozone layer.

The Ozone Secretariat, based in Nairobi, Kenya, has confirmed receipt of notification from the United Nations Headquarters in New York on the deposition of the instruments of ratification from Grenada.  The Ozone Secretariat has already extended congratulations to the Government of Grenada on this milestone achievement.

In addition to been the 37th Party to ratify the Kigali Amendment, Grenada is the third country in the Caribbean to achieve early ratification, behind Trinidad and Tobago whose was the first and Barbados, the second.

20180524_130113St. George’s, Grenada, Thursday May 24th, 2018: The Government of Grenada is the receipient of thirty (30) mini splits air-conditioning units from the Government of Germany, through the implementing agency GIZ, to be used for a demonstration project to promote the use of natural refrigerants in Grenada.

This initiative is part of the Cool Contributions fighting Climate Change (C4) Project that is executed by the National Ozone Unit in the Energy Division of Ministry of Infrastructure Development, Public Utilities, Energy, Transpot and Implementation. This demonstration project, which is the first of its kind in the Caribbean, seeks also to promote energy efficiency in the cooling sector and to reduce direct and indirect emissions of greenhouse gases (GHG). The project will collect, compare and analyze data between, already installed units using synthetic refrigerants and the new systems using natural refrigerants, R-290. The information gathered from the project would be used to drive a robust public awareness and educational campaign to promote the use of natural refrigerant technology.

The NOU has already engaged entities in the private and public sector to participate in the demonstration project.  The air conditions received (20, 18,000 BTU/h and 10, 12,000 BTU/h) operates with the natural refrigerant R-290 (propane). Natural refrigerants are one of the recommended alternatives to replace the high global warming refrigerants and have the following advantages:

  • Greater energy efficiency
  • very good thermodynamic properties
  • no negative impact on the environment
    • zero ozone depleting potential (ODP)
    • very negligible global warming potential (GWP,2)
  • Requires less refrigerant charge (40%)
  • Quieter operation (less noise)
  • lower operating pressures (extends the life of the compressor)

The AC units were received by the Honorable, Gregory Bowen, Minister under whose portfolio the National Ozone Unit falls.  During the brief hand over ceremony, Minister Bowen expressed the government’s gratitude to the Government of Germany and GIZ and reiterated that the use of these energy efficient AC units can reduce the demand for electricity by 50% and make it more afffordable for ordinary citizens. He further lamented, that energy efficiency and environmental preservation should be a priority in the context of reducing green house gas emissions, especially when the global demand for comfort cooling is expected to triple by the year 2050.

Also attending the ceremony was Permanent Secretary, Patricia Clarke, Head of GIZ, Grenada, Dieter Rottenburer and National Ozone  Offcier, Leslie Smith and the public and private sector participant of the project.

 

 

 

Friday May 18th, 2018, St. George’s, Grenada:  Two local appliance stores in St. George’s are joining forces with the National Ozone Unit (NOU) and the Cool Contributions fighting Climate Change (C4) Project to promote the use of Natural Refrigerants in refrigeration systems.

The NOU is providing magnetic stickers to to the two appliance stores to be affixed to every refrigerator that is purchased using the natural refrigerants, R-600a.

This initiative is part of the NOU’s trust to replace the high global warming refrigerants, (such as R-134a), that is used in these appliances with alternatives that are environmentally friendly and at the same time more energy efficient.

R-600a (isobutane) is used as a replacement for R-12 and R-134a refrigerants in domestic refrigerators and small commercial refrigerators. This refrigerant has an ozone depleting potential (ODP) of zero and a negligible global warming potential (GWP) of 2.  Additionally, it has very good thermodynamic properties and very good cooling capacity.

Other advantages of this type of refrigerators are:

  • very energy efficient
  • cheaper and requires less refrigerant charge,
  • operate at  lower pressures and extends the life of the compressors
  • operates with less noise (quieter)

The two companies participating in this initiative are Courts grenada Limited (UNICOMER) and L A Purcell.

St. George’s, Grenada: The National Ozone Unit (NOU) in collaboration with GIZ, under the “Cool Contributions fighting Climate Change” (C4) Project, recently launched two (2) publications on Natural Refrigerants.

The publications are aimed at sensitizing the public on the application of natural refrigerants as one of the long term, environmentally friendly, energy efficient alternative technology available for the refrigeration and air conditioning (RAC) sector.

One of the publications provides technical information designed to update the technicians and importers of RAC equipmet and refrigerants, while the other contains general information and is directed to the end users of RAC equipment.

Natural refrigerants have been used for decades but have become increasingly popular in recent times as a longer term, environmentally friendly (ODP=0, GWP=2)*, with energy  efficiency advantages. The NOU together with the C4 Project is promoting the widespread use of natural refrigerants in Grenada. Ultimately the goal is to reduce the use of green house gases (GHGs) and the emissions from the energy input required to operate RAC equipment. This will contribute towards Grenada meeting its Nationally Determined Contributions (NDCs) as well as its other commitments under the Kigali Amendment to the Montreal Protocol.

The publications feature three of the most commonly used natural refrigerants: hydrocarbons, carbon dioxide and ammonia, which are used in a wide range of applications including, domestic refrigerators, unitary/split air condition systems and commercial and industrial refrigeration systems, among others.

The publications are also part of the NOU’s public awareness and educational outreach program to promote the use of low GWP alternatives in the refrigeration and conditioning sector in Grenada.

St. George’s, Grenada. May 15th, 2018: Stakeholders in the refrigeration and air conditioning (RAC) sector in Grenada met on Tuesday May 15th, 2018, at the conference room of the Grenada Bureau of Standards (GDBS) during a National Public Consultation organized by the National Ozone Unit (NOU) in collaboration with the GDBS to provide comments and to discuss the draft standard for the Safe use, Handling, Storage and Transportation of Refrigerants, including Flammable Refrigerants.

Participants at the consultation represented a wide cross section of the RAC sector, including: the Grenada Refrigeration, Air Conditioning and Ventilating Association (GRAVA), servicing companies, importers, training institutions, Customs, Chamber of Industry and Commerce and end users.

Chairperson of the technical committee for the development of the draft standard and National Ozone Officer, Mr. Leslie Smith, during his introductory remarks lamented on the importance for having the standard in place in light of the introduction of low global warming potential (GWP) alternatives into the country, many of which have concerns with toxicity, flammability and high operating pressures.  He further indicated that this initiative is a clear indication that Grenada is leaving no stone un-turned to convince the manufacturers of these RAC equipment that all the necessary measures are being put  in place to ensure the safe application of these technologies. This situation has been identified as one of the barriers hindering the uptake of such technologies. Additionally, the NOU has been responsible to providing training for over 80% of the RAC technicians in Grenada in natural refrigerant technology.

This national consultation was essentially a second attempt to acquire public comments on the draft standard, since the official period for public comments ended on March 31st, 2018. With the comments provided from the consultation, the final draft will be submitted to the Council of the GDBS for approval.  This will be the second standard to be approved for the RAC sector following the establishment of the standard for the labeling of refrigerant containers that was established in September 2016.
