Small steps towards a giant leap! Parties to the Montreal Protocol continue discussions on HFCs

Last week saw another step towards a global agreement on the phase down of ozone depleting substances at the United Nations Conference Centre in Bangkok. The event started with a buzz around the new amendment proposals to the Montreal Protocol.

The week began with the Workshop from 20-21 April 2015 on Hydrofluorocarbon (HFC) Management and possible replacement solutions in their various uses, followed by the Thirty-fifth meeting of the Open-ended Working Group (OEWG 35) of the parties to the Montreal Protocol on Substances that Deplete the Ozone Layer, from 22-24 April 2015, which focused on HFC management. This event gathered over 350 delegates representing governments, UN agencies, groups and committees of experts on the Montreal Protocol, non-governmental organizations and the industrial sector…

Didier Coulomb, IIR Director, attended both these events as an Intergovernmental Organization representative.

The back-to-back Workshop (see below) and OEWG 35 were mandated to continue discussions on all issues related to HFC management, including an emphasis on high-ambient temperature and safety requirements, as well as energy efficiency.

The workshop focused on technical aspects of HFC management. Its conclusions were presented to OEWG 35 for further consideration and discussion by the Parties.

OEWG 35 opened on 22 April for focused discussions on HFCs. Delegates received an overview of the abundance, trends and projections of HFCs in the atmosphere and their implications; and an overview of HFC production, consumption patterns and trends.

The United Nations Environmental Programme (UNEP) received two amendments sent by North America (USA, Canada, Mexico) and by India. The North American proposal, similar to previous ones, showed a willingness for compromise while the Indian one proposed a 2030 start for HFC phase down in Article 5 countries (developing countries).

Other highlights included a draft proposal submitted by African states on processes to regulate HFC production and consumption, and EU willingness to submit another amendment proposal by the end of April 2015.

OEWG 35 ended the day with a debate regarding potential synergies with the UNFCCC (United Nations Framework Convention on Climate Change), followed by an initial discussion on possible policy objectives for any HFC management policy and legal framework under the Montreal Protocol.

On Thursday, 23 April, OEWG 35 spent most of the day debating previously mentioned key issues for discussions towards a possible HFC management policy and legal framework under the Montreal Protocol, including: phase-down, taking into account hydrochlorofluorocarbon (HCFC) phase-out; means to address sector- and country-specific challenges; strengthening existing means of implementation; and capacity-building, technology transfer, funding requirements and financial mechanism.

Senegal and Zimbabwe, on behalf of the Africa Group, submitted a conference room paper (CRP) which called for the creation of a contact group to consider proposals to amend the Montreal Protocol and suggested specific issues that should be considered by such a group.

Several countries (Arabic countries, Pakistan, Indonesia, some Latin American countries) showed reluctance to detailed discussion of the amendments presented since they felt that further reflection was needed. No agreement was made to create a formal contact group.

On the final day, informal discussions led to an agreement to continue work intersessionally before the next meeting in July 2015 in Paris, in an informal manner to study the feasibility and ways of managing HFCs, including challenges set out in an annex, with a view to the establishment of a contact group.

Although no concrete result was obtained, and more in depth talks are necessary, for the first time all the countries agreed to converse. It is very likely that if the parallel negotiations on climate change, to conclude in December in Paris, are successful, a decision to phase down HFCs under the Montreal Protocol in 2016 will be conceivable.

More about the workshop

Each workshop session, six in all, was opened by a brief presentation; during the first day the three sessions covered were:

  • “Challenges and opportunities in addressing high global warming potential (GWP) HFCs in the refrigeration sector”
  • “Challenges and opportunities in addressing high-GWP HFCs in the stationary air-conditioning and heat pump sector”
  • “Challenges and opportunities in addressing high-GWP HFCs in mobile air-conditioning”

Sessions were followed by feedback and discussion by a panel of technology stakeholders, with questions from the audience, including inputs from an online board for posting questions.

Cited during the workshop were the different barriers to low GWP refrigerants stemming from standards and costs as well as the need for training, safety awareness, and energy efficiency.

Equally important to participants were domestic legislation, industry initiatives, and accessibility to low-GWP alternatives to HFCs in Article 5 countries.

The second day of the workshop also presented three sessions covering the following topics:

  • "Challenges and opportunities in addressing high-GWP HFCs in the foam sector"
  • Part 1, "Costs of conversion, intellectual property rights, accessibility to low-GWP alternatives and timeline of availability for new technologies"
  • Part 2, "Energy efficiency, safety, industry’s response to low-GWP policies"
  • "Key conclusions relevant to policymaking on technical management of HFCs"

Among the points highlighted during this second day were the capabilities of industry to provide much needed low-GWP solutions and technologies; regulatory certainty is required in order to accelerate investment and the move to low GWP.

Ammonia and CO2 refrigeration technologies at the forefront

Ohrid 2015:  Building on the success of previous conferences held biennially since 2005, the 6th in the series attracted a wide scope of key industry stakeholders, ranging from manufacturers, end users to research institutions.

From 40 different countries, participants seized the opportunity to meet and exchange with experts from well-known international companies such as Johnson Controls (Sabroe), GEA Refrigeration, Mayekawa (Mycom), Bitzer, Dorin, Baltimore Aircoil, Evapco, Guentner, Lu-Ve Group, Garden City Ammonia Group, Danfoss, Int. Copper Alliance, Friterm, RV Cooling Tech, EPTA and Unilever, to name but a few.

In light of the intense debate on the F-Gas regulation and its implementation worldwide, as well as proposed amendments to the Montreal Protocol for the phase-down of HFCs, the conference provided the ideal forum for the exchange of knowledge on ammonia and CO2 technologies, and their combination, as the most viable option in future.

In a region where ammonia was, and still is, a traditional refrigerant, this event provided the perfect opportunity to introduce CO2 as a refrigerant and focused on:

  • greener alternatives
  • advancing future green technologies
  • economic benefits of these technologies.

Similarly, as the event was held in a country where refrigeration and related technologies are becoming increasingly important, it attracted many from developing countries where similar matters are of equal concern, presenting strategic opportunities for many.

The focus

Held on 16-18 April 2015 in Ohrid, Macedonia, the 6th Ammonia and CO2 Refrigeration Technologies Conference triumphed once again. It aimed to clarify future uncertainties regarding both the Montreal and the Kyoto Protocols and environmental regulations applicable to natural refrigerants.

This year the conference provided an enhanced programme including CO2 refrigeration technologies which focused on the global trend towards using natural refrigerant. More specifically ammonia, carbon dioxide and hydrocarbons used in various refrigeration applications worldwide.

Consequently, conference participation increased, from approximately 100 individuals in the past to 140 participants this year.

Of all refrigerants applied today, ammonia and CO2 are the oldest; having been used since the 19th century. With the development and use of more ammonia and CO2 refrigerants, the event remains in line with growing trends towards employing environmentally friendly refrigeration technologies.

The programme

With the 53 high quality research papers submitted from 23 countries, the scientific and technical programme covered issues at the heart of new technologies and applications of ammonia and CO2 as refrigerants.

Topics included:

  • Design of modern ammonia (NH3) systems and technological innovation
  • Design of carbon dioxide (CO2) refrigeration and heat pump systems
  • New innovative components
  • Energy efficiency of ammonia and CO2 refrigerating systems
  • Applications of ammonia and CO2 refrigeration
  • Absorption machines
  • Ammonia and CO2 systems in developing countries
  • Technical and safety issues; Guidelines and training materials
  • Public awareness of the image and benefits of natural refrigerants.

Keynote speakers

As in previous years, the 6th Ammonia and CO2 Refrigeration Technologies Conference did not fail to impress with a b line-up of international keynote speakers and lectures delivered by:

  • Andy Pearson, UK, Star Refrigeration Ltd on “Why is ammonia such a good refrigerant?”
  • PredragHrnjak, USA, University of Illinois on “In-tube evaporation of CO2: visualization and effect of oil”
  • Armin Hafner, Norway, SINTEF Energi AS on “2020 Perspectives for CO2 refrigeration and heat pump systems”
  • Eric Smith, USA, Int. Institute of Ammonia Refrigeration on “Navigating the regulatory environment and opportunities for new technologies in the U.S.”
  • Maurice Young, UK, Maurice Young Consulting Ltd on “The compliance of ammonia refrigeration plants with the dangerous substances and explosive atmospheres regulations 2002 (DSEAR) as required by the EU ATEX directives”

During the closing ceremony Prof. Risto Ciconkov (see photo), president of the conference Organizing Committee, stated “Instead of being occupied with a phase-down of HFC gases, drop-in refrigerants, retrofit of systems, environmental taxes, restrictions, calculations of F-gas quotas, let’s start with a new approach: PHASE-IN of natural refrigerants.”
