have been 4 00:00:15,770 --> 00:00:18,660 burning fossil fuels like coal and oil 5 00:00:18,660 --> 00:00:21,170 to generate electricity. 6 00:00:21,170 --> 00:00:24,370 Hi, I'm Professor Nor Aisha Saidina Amin, 7 00:00:24,370 --> 00:00:26,170 professor of chemical engineering, 8 00:00:26,170 --> 00:00:30,530 and a visiting fellow with the MIT UTM Sustainable Cities 9 00:00:30,530 --> 00:00:31,770 Program. 10 00:00:31,770 --> 00:00:34,800 My research is focused on renewable energy, 11 00:00:34,800 --> 00:00:37,400 and today I am going to talk about climate 12 00:00:37,400 --> 00:00:39,690 change and renewable energy. 13 00:00:39,690 --> 00:00:42,340 The primary product of burning of fossil fuels 14 00:00:42,340 --> 00:00:44,300 is carbon dioxide. 15 00:00:44,300 --> 00:00:47,820 For centuries, the amount of carbon dioxide emissions 16 00:00:47,820 --> 00:00:51,980 in the atmosphere was 300 parts per million. 17 00:00:51,980 --> 00:00:55,480 But carbon dioxide have increased dramatically 18 00:00:55,480 --> 00:00:57,620 and reached an unprecedented value 19 00:00:57,620 --> 00:01:00,150 of about 400 parts per million. 20 00:01:00,150 --> 00:01:02,290 High levels of carbon dioxide emissions 21 00:01:02,290 --> 00:01:04,540 are linked to climate change, which 22 00:01:04,540 --> 00:01:08,420 has led to increasing temperatures, melting glaciers, 23 00:01:08,420 --> 00:01:12,120 rising sea level, changing rain and snow patterns, 24 00:01:12,120 --> 00:01:17,580 and also drought, floods, and other extreme events. 25 00:01:17,580 --> 00:01:20,150 Climate change is an important issue, 26 00:01:20,150 --> 00:01:23,410 and reducing carbon emission is a challenge. 27 00:01:23,410 --> 00:01:27,490 In December 2015, world leaders convened in Paris 28 00:01:27,490 --> 00:01:30,430 to discuss the reduction of carbon emissions and climate 29 00:01:30,430 --> 00:01:33,600 change impacts at a United Nations Global climate 30 00:01:33,600 -->

NOR AISHAH SAIDINA AMIN: One of the ways 42 00:02:16,440 --> 00:02:18,870 to address climate change is to replace 43 00:02:18,870 --> 00:02:22,710 fossil fuels with renewable energy for electricity 44 00:02:22,710 --> 00:02:24,050 production. 45 00:02:24,050 --> 00:02:27,310 Carbon emissions from renewable energy power plants 46 00:02:27,310 --> 00:02:31,500 are much lower compared to those that run with fossil fuels. 47 00:02:31,500 --> 00:02:34,860 According to the Energy Information Administration, 48 00:02:34,860 --> 00:02:37,270 although there are plenty of renewable resources 49 00:02:37,270 --> 00:02:42,220 available on Earth, only 10% of the world's energy output 50 00:02:42,220 --> 00:02:44,180 is from renewable sources. 51 00:02:44,180 --> 00:02:46,310 Types of renewable energy include 52 00:02:46,310 --> 00:02:49,720 solar, geothermal, wind, and biomass. 53 00:02:52,350 --> 00:02:53,970 There are many lessons that can be 54 00:02:53,970 --> 00:02:57,850 learned from Malaysia's success with using renewable energy. 55 00:02:57,850 --> 00:03:00,710 Given Malaysia's tropical biodiversity, 56 00:03:00,710 --> 00:03:04,520 conversion of biomass to energy is a promising approach 57 00:03:04,520 --> 00:03:07,572 to establishing sustainable energy production. 58 00:03:07,572 --> 00:03:09,030 JOHN WOODLEY: Malaysia will also be 59 00:03:09,030 --> 00:03:10,510 an excellent example where there is 60 00:03:10,510 --> 00:03:12,670 plenty of agricultural waste. 61 00:03:12,670 --> 00:03:14,420 And it could be a wonderful idea to try 62 00:03:14,420 --> 00:03:19,730 to use that waste in a way which brings a little bit of value 63 00:03:19,730 --> 00:03:23,390 to your community, to the country, but at the same time, 64 00:03:23,390 --> 00:03:26,779 can help us to reduce carbon dioxide emissions. 65 00:03:26,779 --> 00:03:28,570 NOR AISHAH SAIDINA AMIN: Situated in Johor, 66 00:03:28,570 --> 00:03:32,210 the most southern state in peninsula Malaysia, Iskandar, 67 00:03:32,210 --> 00:03:35,030 Malaysia is a new development region that 68 00:03:35,030 --> 00:03:37,620 advocates low carbon emission. 69 00:03:37,620 --> 00:03:39,950 Most of its carbon dioxide emission 70 00:03:39,950 --> 00:03:43,140 are from the electricity and heating sector. 71 00:03:43,140 --> 00:03:46,000 As documented in their low carbon plan. 72 00:03:46,000 --> 00:03:49,030 Iskandar, Malaysia is projected to be a sustainable 73 00:03:49,030 --> 00:03:54,470 city by 2025 with only $18.9 million tons of carbon dioxide 74 00:03:54,470 --> 00:03:59,430 emissions, a 40% reduction from 2005 levels. 75 00:03:59,430 --> 00:04:02,280 How can this Iskandar, Malaysia achieve this target? 76 00:04:02,280 --> 00:04:05,280 One of the methods is to utilize waste 77 00:04:05,280 --> 00:04:09,790 from the oil pump industry to generate heat and electricity. 78 00:04:09,790 --> 00:04:13,870 Iskandar, Malaysia is easily accessible to large areas 79 00:04:13,870 --> 00:04:16,180 of oil palm plantation. 80 00:04:16,180 --> 00:04:20,350 The oil pump industry produces waste such as empty fruit bunch 81 00:04:20,350 --> 00:04:22,480 and palm oil mill effluent. 82 00:04:22,480 --> 00:04:26,400 Empty fruit bunch is the residue you produced when palm fruit is 83 00:04:26,400 --> 00:04:30,000 taken from a fresh fruit bunch in the initial process 84 00:04:30,000 --> 00:04:31,900 of a palm oil production. 85 00:04:31,900 --> 00:04:35,600 Palm oil mill effluent is the voluminous liquid waste 86 00:04:35,600 --> 00:04:39,240 that comes from the sterilization and clarification 87 00:04:39,240 --> 00:04:42,840 processes in milling oil palm. 88 00:04:42,840 --> 00:04:46,070 By utilizing waste, carbon dioxide emissions 89 00:04:46,070 --> 00:04:49,620 can be significantly reduced and make the air 90 00:04:49,620 --> 00:04:52,850 in the region cleaner and healthier. 91 00:04:52,850 --> 00:04:55,600 One way to measure carbon dioxide emissions 92 00:04:55,600 --> 00:04:58,230 is to use an integrated model that 93 00:04:58,230 --> 00:05:02,830 takes into account direct and indirect carbon dioxide 94 00:05:02,830 --> 00:05:04,100 emissions. 95 00:05:04,100 --> 00:05:06,590 The concept of the model used to probe 96 00:05:06,590 --> 00:05:10,980 quite a systematic and comprehensive carbon accounting 97 00:05:10,980 --> 00:05:13,730 to evaluate carbon performance, as well 98 00:05:13,730 --> 00:05:16,260 as to determine the potential carbon emission 99 00:05:16,260 --> 00:05:18,754 reduction in the process. 100 00:05:18,754 --> 00:05:21,820 The model calculates carbon dioxide emissions from three 101 00:05:21,820 --> 00:05:25,560 by biomass power plants-- the bio-xcell plant, Kulim group 102 00:05:25,560 --> 00:05:28,580 plant, and Ronser biogas plant. 103 00:05:28,580 --> 00:05:32,230 Initially, carbon accounting centers for each process 104 00:05:32,230 --> 00:05:34,900 is divided into smaller units. 105 00:05:34,900 --> 00:05:38,450 Next, the total monthly carbon emission equivalent 106 00:05:38,450 --> 00:05:41,550 is determined, followed by calculation of the carbon 107 00:05:41,550 --> 00:05:44,890 dioxide emissions and carbon emission index 108 00:05:44,890 --> 00:05:47,710 across the carbon performance indicators. 109 00:05:47,710 --> 00:05:50,490 Strategies for reduction of carbon emissions 110 00:05:50,490 --> 00:05:52,070 are then implemented. 111 00:05:52,070 --> 00:05:54,280 The five main emission contributors 112 00:05:54,280 --> 00:05:57,860 are identified as carbon performance indicators. 113 00:05:57,860 --> 00:06:02,660 These are fuel, water, and electricity consumption. 114 00:06:02,660 --> 00:06:06,720 And also waste water and solid waste generation. 115 00:06:06,720 --> 00:06:10,030 Empty fruit bunch is fed into Bio-Xcell Plant 116 00:06:10,030 --> 00:06:13,990 to generate steam and electricity. 117 00:06:13,990 --> 00:06:17,180 Empty fruit bunch is shredded and then formed 118 00:06:17,180 --> 00:06:19,490 as solid pellets. 119 00:06:19,490 --> 00:06:22,510 The pellets are used as fuels for the boilers 120 00:06:22,510 --> 00:06:23,990 to produce steam. 121 00:06:23,990 --> 00:06:28,100 The steam turbine then generates electricity. 122 00:06:28,100 --> 00:06:32,010 Meanwhile, Kulim and Ronser utilize palm oil mill effluent. 123 00:06:32,010 --> 00:06:35,850 The effluent is retained in an anaerobic digester 124 00:06:35,850 --> 00:06:37,580 to produce bio gas. 125 00:06:37,580 --> 00:06:41,480 The gas runs the turbine to generate electricity. 126 00:06:41,480 --> 00:06:43,650 The total monthly carbon dioxide emissions 127 00:06:43,650 --> 00:06:45,920 before and after the implementation 128 00:06:45,920 --> 00:06:50,040 of the reductions strategies are exhibited in figure one, 129 00:06:50,040 --> 00:06:54,660 showing a 27% emissions reduction at Bio-Xcell, 130 00:06:54,660 --> 00:06:59,920 15% at Kulim, and 41% at Ronser. 131 00:06:59,920 --> 00:07:02,750 Figure two compares the carbon emission index 132 00:07:02,750 --> 00:07:06,170 after implementing the reduction strategies. 133 00:07:06,170 --> 00:07:08,940 In general, all performance indicators 134 00:07:08,940 --> 00:07:12,450 show reduced emissions after innovative strategies 135 00:07:12,450 --> 00:07:14,020 are implemented. 136 00:07:14,020 --> 00:07:16,520 In Bio-Xcell, the carbon emission index 137 00:07:16,520 --> 00:07:21,110 for fuel and water consumption decreased significantly 138 00:07:21,110 --> 00:07:25,540 after solid, empty fruit bunches replaced the shredded ones. 139 00:07:25,540 --> 00:07:28,345 In addition, a reduction of solid waste generation 140 00:07:28,345 --> 00:07:31,550 in runs of bio gas was also registered 141 00:07:31,550 --> 00:07:35,070 after water from the effluent is recycled. 142 00:07:35,070 --> 00:07:37,910 Carbon dioxide emissions can be easily predicted 143 00:07:37,910 --> 00:07:39,790 using the income model. 144 00:07:39,790 --> 00:07:42,930 A power plant that utilizes biomass contributes 145 00:07:42,930 --> 00:07:46,470 less to climate change since the carbon dioxide released 146 00:07:46,470 --> 00:07:49,470 is absorbed by trees through photosynthesis. 147 00:07:49,470 --> 00:07:51,530 The process is cyclical. 148 00:07:51,530 --> 00:07:53,560 The industry could play a big role 149 00:07:53,560 --> 00:07:55,600 in reducing carbon dioxide emissions 150 00:07:55,600 --> 00:07:58,620 by switching to renewable energy for generating electricity. 151 00:07:58,620
