On Is Latin America and the Caribbean turning on to energy efficiency?

The Caribbean Renewable Energy Forum (CREF 2012)  will be co-hosted with the Government of Puerto Rico at the Ritz-Carlton, San Juan, from October 15th-17th.

The agenda for CREF 2012 is a microcosm for the conference as a whole, a place where Caribbean leaders sit alongside household names in international renewables development. For 2012, delegates will enjoy a particularly rich and diverse line-up of speakers tackling, as always, the defining issues confronting our region today. Topics to be covered will include

• Caribbean Ministerial Roundtable: the policy-makers' perspective
• Project Bankability - the view from the capital-providers
• Utilities & Distributed Generation: A wedding or a future apart?
• Puerto Rico - update and investment opportunities
• Regional Interconnection: practical, politicial, financial perspectives
• The Technological Landscape: what's new, what works, what are the costs?
• Waste-to-Energy - over-hyped or a long-term solution for the Caribbean?
• Case-study: The Atlantic Canada RE Experience - lessons learned and applications in the Caribbean.

On Can increased energy access levels go hand-in-hand with lowering our climate emissions?

The Green Industry Platform is a global high-level multi-stakeholder partnership intended to act as a forum for catalyzing, mobilizing and mainstreaming action on Green Industry around the world. It provides a framework for bringing together governmental, business and civil society leaders to secure concrete commitments and mobilize action in support of the Green Industry agenda.

By encouraging the more efficient use of energy and raw materials in manufacturing processes and services, the Platform will contribute both to cleaner and more competitive industrial development, and will help reduce pollution and reliance on unsustainable use of natural resources.

Business, governments and civil society organizations are invited to review and sign the Green Industry Platform's Statement of Support in order to indicate their willingness to become a member of the Platform.

On Can increased energy access levels go hand-in-hand with lowering our climate emissions?

Significant commitments to action in the context of the UN’s Sustainable Energy for All initiative (SE4ALL) recently announced include;

  • GDF Suez will invest in approximately 50 local energy entrepreneurship projects in developing countries by 2020. It will also increase both its own energy efficiency by 40% by 2017 as well as its installed capacity of renewable energy by 50% from 2009-2015.
  • d.Light Design, a social entrepreneur, is committed to providing solar lamps to 30 million people in more than 40 countries by 2015;
  • Ghana, one of the first countries to partner with the initiative, is developing a national energy action plan to support capacity-development and innovative financing mechanisms.
  • Barbados will increase its use of renewable energy to 29% of all electricity consumption by 2029;
  • The European Commission announced a new initiative called "Energising Development" that will provide access to sustainable energy services to 500 million people by 2030 and create a Technical Assistance facility supported by approximately USD $63 million over the next two years;
  • The United Nations Foundation is facilitating a global Energy Access Practitioner Network, bringing together more than 200 organizations from civil society to collaborate on the delivery of energy services and solutions related to electrification in a range of developing country contexts and;
  • Members of rock band Linkin Park have launched the "Power the World" campaign and aim to deliver one million signatures to world leaders at Rio+20 urging an end to energy poverty. The campaign also collects pledges for We Care Solar to deliver their novel Solar Suitcases to health care practitioners in need of reliable lighting.

On Which Nations Have Reduced Carbon Intensity the Fastest?

OK then, the UK did it by abandoning manufacturing, increasing imports, and switching from coal to natural gas (although I seem to remember that, during the Miners Strike, Thatcher imported massive amounts of coal from Poland...). Anyway, even with this amendment, I maintain the gist of my comment...

On Which Nations Have Reduced Carbon Intensity the Fastest?

So, Sweden and France achieved rapid rates of decarbonization of their economies principally by scaling up new nuclear power programs. The UK did it by abandoning manufacturing and increasing imports. And Ireland did it by abandoning its relatively energy-intensive agriculture sector. Really, not a great package to crow about -- a greater reliance on nuclear power and shifting the carbon cost of producing manufactured goods and food for export to other (developing) countries. Net result: global energy use and subsequent carbon output will increase....!!!!

On Ushering in a Hydrogen Economy

I am pasting below the reply to Nathan Wilson's comment sent by Dr. Mustafa Hatipoglu, Managing Director of UNIDO-ICHET (United Nations Industrial Development Organization - International Centre for Hydrogen Energy Technologies), who is not a member of this group.


The idea of using hydrogen as a fuel in transportation or in residential applications or other stationary applications has never been debunked. On the contrary, commercial applications have started in the recent years and will sharply increase after 2015. Those facts and recent developments can be found in the press releases of the related companies and the R&D institutes.

In 2009, the leading automotive companies such as Daimler, Toyota, Honda, Ford, General Motor, Hyundai, Kia, an Nissan produced a joint statement on the development of hydrogen fuel cell cars and their commercialization from 2015 onwards. About two months ago, Daimler and Toyota confirmed their plan to start commercialization in 2015. By 2020, the other companies will complete their commercialization plans.

In parallel with the automotive manufacturers, the ‘Hydrogen Mobility Initiative’ partners: Linde, Shell, Daimler, ENBW, OMV, Total, Vattenfall & NOW Gmbh National Organization Hydrogen and Fuel Cell Technology, announced their collaboration on spreading hydrogen fueling stations in Germany.

Thus, thee are not dreams but realities. One can find enough information if one enters the websites of those companies or participates in dedicated conferences and workshops.

As an example, HONDA/FCX-Clarity FC Car has a 100kW PEM Fuel Cell and 350 bar H2 Tank. Its driving range is close to 500 km. TOYOTA nowadays employs 700 bar H2 tanks and its driving range is a little more than 800 km. The websites of Honda, Toyota, Daimler and the others should be checked. Moreover, I have also ridden those cars in Japan. The performance, cold start, reliability and hydrogen storage problems of hydrogen fuel cell cars are already been solved. HONDA is also renting FCX-Clarity car in some countries (USA, Germany) at a monthly rate of 600 USD.

We should keep in mind that the energy storing capacity of hydrogen is almost three times more than that of gasoline. It means that the weight of hydrogen stored in compressed gas form in the car to drive a certain mileage is three times less than the weight of gasoline needed.

Currently, the automotive companies prefer to use compressed hydrogen (350 or 700 bar) in fuel cell cars. BMW selected liquid hydrogen to use in their prototypes, but later on gave up, since it is more costly than gaseous hydrogen.

Also, to produce hydrogen in a plant and then carry with lorries to fueling stations is not the way preferred by the gas companies. They prefer to produce hydrogen in site either by water electrolyzing or natural gas steam reforming.

Using ammonia as fuel in internal combustion engines and fuel cells is still under research. Can it be more efficient and feasible to convert hydrogen to ammonia and then reconvert it to hydrogen just for transporting? The toxic effect of ammonia is another issue but this should be cleared up over time. But, in any case, the automotive companies currently prefer to use compressed hydrogen as fuel for fuel cell cars.
