Keep Commitment To Transition To Low-Carbon Economy, Urges UN Climate Change Office

August 26, 2016 Webmaster

The United Nations (UN) climate change secretariat has added its voice to concerns being raised about a proposal made by China’s Jiuquan Iron and Steel Company (JISCO) for the construction of a coal-fired plant in St Elizabeth.

The proposal was announced after JISCO completed a deal to acquire the Alpart alumina factory from Russian company, UC Rusal. The new Chinese owners plan to upgrade the plant with an aluminum smelter that would be powered by a 1,000-megawatt coal-fired plant.

Based on calculations provided by the CoalSwarm Global Plant Tracker, a 1,000 megawatt coal plant would produce 5.6-5.8 million tonnes of CO2 annually, increasing Jamaica’s emissions of CO2 by 79-82 per cent. Greenpeace campaigner Lauri Myllyvirta has said that the construction of the plant would violate the Paris Agreement signed under the UN Framework Convention on Climate Change (UNFCCC).

Commenting on the possible impact of the proposed coal plant on Jamaica’s UNFCCC standing, Nick Nuttall, UNFCCC spokesperson, pointed out that Jamaica had submitted an ambitious national climate action plan to the UN aimed at achieving a nearly eight per cent emission reduction by 2030. He also argued that the action plan promised commitments of greater investment in greener sources of homegrown energy such as wind and solar power rather than increases in oft-imported fossil fuels.

He argued that economic growth and job creation were not antithetical to environmental protection.

“Many complex choices will be made by governments over the years and decades to come, including with regard to energy sources, but today, there is an ever clearer consensus that overcoming poverty and growing GDP, which are critical for developing countries, can go hand in hand with generating new kinds of high-tech jobs; creating healthier, less polluted societies and a transition to a low carbon economy …,” he said in an email response to The Gleaner.

Prime Minister Andrew Holness has said that the Government is committed to balancing its economic-growth aspirations with its environmental and international commitments.

Comments solicited from Jamaica’s mission to the UN and the Ministry of Foreign Affairs were not forthcoming up to press time.

Engineer Says Alpart Could Be Operated Solely On Renewable Energy

August 24, 2016 Webmaster

Consulting engineer Howard Chin is making the case for the Alpart plant, which was recently acquired by Chinese firm Jiuquan Iron and Steel Company Ltd (JISCO), to be operated entirely using renewable energy.

JISCO has announced plans to invest US$2 billion to expand the plant which will see the addition of an aluminium smelter powered by a coal-fired plant.

Chin has, however, argued that the heat that would be generated from the coal-fired plant could be detrimental to aquatic, plant and animal life in and around the Black River area, and as such, renewable-energy sources should be considered.

“Cooling the power plant and running the bauxite refinery requires a lot of water. How hot would the Black River become downstream of Alpart? Hot enough to kill animal life? Certainly, NEPA (National Environment and Planning Agency) is not answering these questions which have to be answered. Nor do they have the technical capability to do so,” Chin said in an emailed response to The Gleaner.

STORAGE POWER PLANT

In recognition of the problem of storage capacity associated with renewables, Chin explained that a large pumped hydroelectric storage power plant could be used to power the alumina plant in the first instance.

“It could be done using a large renewable energy system backed up by a pumped storage system,” he said.

Pumped hydroelectric storage facilities store energy in the form of water in an upper reservoir, pumped from another reservoir at a lower elevation. During periods of high electricity demand, power is generated by releasing the stored water through turbines in the same manner as a conventional hydropower station. During periods of low demand, the upper reservoir is recharged by using lower-cost electricity from the grid to pump the water back to the upper reservoir.

Turning his attention to the Bayer Process, which would be used to produce aluminium should the Chinese go ahead with plans to build a smelter at Alpart, Chin observed that the heat given off could be transferred to the alumina refinery, which requires it in large quantities. According to the former Jamaica Institution of Engineers president, the smelter could also be powered by renewable energy.

“The alumina refinery needs a lot of heat. The aluminium smelter needs electricity and ends up giving off a lot of heat. Frankly, it might be possible to run the combined alumina and aluminium refining plant on a mostly very large renewable-energy system and a very large pumped storage system, and moving the heat from where it is produced to where it is needed,” he said.
