Ensuring the success of cold chains - new GIZ-Proklima study available

Research shows that an estimated 30% of global food production perishes in post-harvest losses. Rising temperatures, population growth and increased urbanization are magnifying the need for adequate cooling. A recent concept paper by the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH examines the barriers and recommendations for food cold chains of fruit and vegetables, dairy, meat, and fish in developing countries.

The study identifies a comprehensive approach involving a broad range of stakeholders pivotal in ensuring the success of a cold chain; shortcomings at any level may jeopardize a cold chains' viability as a whole. Capacity building and training, access to a reliable and affordable energy supply, policy and regulation and improved access to financing are the key building blocks for a functioning cold chain.

The study was carried out by Proklima and HERA (Poverty-oriented Basic Energy Services) of GIZ, and funded by the German Federal Ministry for Economic Cooperation and Development (BMZ). Further details of the study with projects in various developing countries can be downloaded here.

Installing solar cooling plants in Jordan: a practitioner’s handbook

As in most countries, Jordan`s demand for air conditioning is expected to double by 2030 in comparison to 2015. The increase is due to several factors such as a general increase in living standards or the generally increasing temperatures due to climate change. Solar thermal driven refrigeration and air-conditioning (RAC) is particularly attractive to high ambient temperature countries with a high rate of solar radiation.

Within a GIZ-project, two solar thermal cooling units using absorption technology and dry re-cooling were installed in Amman and Petra in 2015. Following this successful installation, a practitioner's handbook describing the planning and implementation of solar thermal cooling technologies has been developed. The guide supports engineers, technicians and maintenance personnel in understanding the available technological options and functionality of the individual components of solar cooling appliances.

The handbook was realized by the project Solar Cooling in Industry and Commerce (SCIC) of GIZ in cooperation with the Ministry of Jordan, and financed by the German Federal Ministry for Environment, Nature Conservation, Building and Nuclear Safety (BMUB). The guide can be downloaded here.

GIZ’s new guidance paper and infographic on advancing NDCs through RAC

Policymakers are guided in their efforts to address their country's RAC&F (RAC and foam) sector, and to include it in their nationally determined contributions (NDCs). It has been estimated that a reduction in the production and consumption of hydrofluorocarbons (HFCs) may provide between 6 and 10% of the total greenhouse gas (GHG) reductions by 2050.

In reaction to the recent developments under the Paris Agreement and the Kigali Amendment, the GIZ-project Cool Contributions fighting Climate Change has published a new guidance for policymakers in the climate, ozone, and energy efficiency sector. The guidance supports the development of strategies to reduce GHG emissions in the RAC&F sector. In many countries, this sector is responsible for an increasingly large share of emissions, which can be mitigated effectively at a low cost. Phasing-out HFCs and improving the energy efficiency in the RAC&F sector can significantly contribute to reaching the climate goals drafted in NDCs, and hereby contribute to reaching the 2°C target set forward in the Paris Agreement.

An infographic summarizing and visualizing the guidance was also published. The poster includes the key steps to introducing climate-friendly and energy-efficient cooling, and the Sustainable Development Goals which are hereby supported. Both the guidance and infographic were published on behalf of the BMUB.

The guidance and poster can be found here:

Project News

GIZ installs first CO2-Ammonia Cascade System in Mauritius

Since 2016 the Université de Mascareignes of Mauritius is providing training on CO2 as a natural refrigerant to contractors and students. The installation of a CO2-Ammonia plant is used to demonstrate the feasibility of climate-friendly, energy-efficient cooling technologies, and to advance the eradication of HFCs. As a small island developing state, Mauritius is bearing proportionally large hardships due to global warming.

With the CO2-Ammonia installation, the country is showcasing its commitment towards a greener world. Not only does the installation demonstrate the feasibility and cost effectiveness of natural refrigerants, but simultaneously a pool of technicians and engineers needed to handle this kind of equipment is being trained. This is a fundamental step for capacity building, and an important step for the transition of hotels and supermarkets to natural refrigerants. University academics are aspiring for the first supermarket installations by 2017. The first CO2-Ammonia plant on the island was installed by GIZ and funded by the BMZ.

Green Cooling Africa Initiative on track

Kenya, Namibia and Ghana have completed their Tier 2 IPCC RAC sector inventories after data verification workshops held in February and March 2017. The inventories will be used to create technological roadmaps to support future funding and mitigation activities in the countries' RAC sectors.

The respective inventories in Kenya, Namibia and Ghana were carried out under the Green Cooling Africa Initiative (GCAI). During the workshops, the data collected based on Tier 2 IPCC methodology was presented and verified, the feedback of relevant stakeholders was integrated and country-specific barriers and requirements were identified. Mauritius has made the fastest progress; the inventory has already been completed and the technology roadmap is in the process of being established.

In Kenya, Namibia and Ghana technology roadmaps based on the completed inventories and including policy recommendations will be formulated and used as grounds for future funding of mitigation actions for the RAC sector. The GCAI is implemented by GIZ and funded by the Climate Technology Centre & Network (CTCN) in Namibia and Mauritius and BMUB in Kenya and Ghana.

Cinnamon-fueled air conditioning: Green cooling Technology Partnership in Sri Lankan Hotels

The tourism sector is a front runner of Sri Lanka's economy; according to the Central Bank of Sri Lanka, the travel and tourism sector accounted for over 10% of the island's overall GDP in 2015. Simultaneously, it is one of the major contributors to the national greenhouse gas (GHG) emissions. A leading hotel chain on the island embarks on an innovative path to reduce its GHG emissions in a climate-friendly way.

The energy efficiency of most hotel facilities in Sri Lanka is low, such that the resulting environmental and climate impacts are considerably greater than those caused by buildings of a similar size. Given its growing significance, mitigation efforts in the RAC sector can contribute significantly to reaching the country's climate targets.

The Jetwing Hotel Group with properties spread across the island was selected as one of three technology partnership projects by the Green Cooling Initiative, implemented by GIZ and funded by the BMUB. The project proposes four key mitigation strategies, which could reduce the GHG emissions by around 50%.

At the hotel Jetwing Blue located in Negombo, an absorption chiller using steam generated in a cinnamon wood-burning boiler has been installed. Cinnamon wood is one of the four most sustainable fuel woods of South Asia due to its cropping cycle of just 6 months, and it is relatively cheap. Only the bark of the tree is used for cinnamon production, such that the wood which would otherwise be wasted lends itself to being used as fuel for cooling purposes.
