    Tonight at 9pm, BBC Two will be showing a program on geo-engineering techniques to 'save' the planet from global warming. Five of the world's top scientists propose five radical scientific inventions which could stop climate change dead in its tracks. The ideas include: a giant sunshade in space to filter out the sun's rays and help cool us down; forests of artificial trees that would breath in carbon dioxide and stop the green house effect and a fleet futuristic yachts that will shoot salt water into the clouds thickening them and cooling the planet.

    Hindustan Petroleum Corporation Limited is to build a biofuel production plant in the tribal belt of Banswara, Rajasthan, India. The petroleum company has acquired 20,000 hectares of low value land in the district, which it plans to commit to growing jatropha and other biofuel crops. The company's chairman said HPCL was also looking for similar wasteland in the state of Chhattisgarh. Zee News - Jan. 15, 2007.

    The Zimbabwean national police begins planting jatropha for a pilot project that must result in a daily production of 1000 liters of biodiesel. The Herald (Harare), Via AllAfrica - Jan. 12, 2007.

    In order to meet its Kyoto obligations and to cut dependence on oil, Japan has started importing biofuels from Brazil and elsewhere. And even though the country has limited local bioenergy potential, its Agriculture Ministry will begin a search for natural resources, including farm products and their residues, that can be used to make biofuels in Japan. To this end, studies will be conducted at 900 locations nationwide over a three-year period. The Japan Times - Jan. 12, 2007.

    Chrysler's chief economist Van Jolissaint has launched an arrogant attack on "quasi-hysterical Europeans" and their attitudes to global warming, calling the Stern Review 'dubious'. The remarks illustrate the yawning gap between opinions on climate change among Europeans and Americans, but they also strengthen the view that announcements by US car makers and legislators about the development of green vehicles are nothing more than window dressing. Today, the EU announced its comprehensive energy policy for the 21st century, with climate change at the center of it. BBC News - Jan. 10, 2007.

    The new Canadian government is investing $840,000 into BioMatera Inc. a biotech company that develops industrial biopolymers (such as PHA) that have wide-scale applications in the plastics, farmaceutical and cosmetics industries. Plant-based biopolymers such as PHA are biodegradable and renewable. Government of Canada - Jan. 9, 2007.

World premiere: biogas fuel cell powers and cools telecom server farm

Server farms have a voracious appetite for energy. On the one hand they use considerable amounts of electricity to function, while on the other hand they need vast amounts of cooling. Some have noticed that rising energy prices are becoming a heavy burden on the IT and telecom industry's servers, which form the backbone of the internet and of global telecommunications. Increases in the energy efficiency of new generations of servers don't keep up with rising energy costs.

In a world premiere, a large server farm in Germany is overcoming the problem by using [*German, or here, *German] what is arguably the cleanest and most efficient energy system currently in existence: a fuel cell that delivers both electricity and cooling, powered by locally produced carbon-negative biogas.

Earlier we reported on the hyper-efficiency of biogas powered fuel cells, which are far more feasible than their hydrogen powered counter-parts because hydrogen production is either costly and energy intensive (if derived from renewables or nuclear) or dirty (when derived from fossil fuels) (earlier post). Biogas can be made locally from the anaerobic fermentation of (waste) biomass and used directly in the high-temperature molten carbonate fuel cell (MCFC). These innovatie systems normally function as highly efficient 'combined heat-and-power' (CHP) units. But using simple physics, heat can be transformed into cold.

München based Power & Air Condition Solution Management GmbH & Co. KG (PACSM), a subsidiary of Deutsche Telekom AG, organises and manages the energy needs of this giant telecoms operator's T-systems server suite, located in the same city. In search of optimised energy solutions, PACSM collaborated with MTU CFC GmbH, the company that develops the biogas powered "Hot Module" we referred to earlier (see picture, click to enlarge). The "hot" segment is transformed into a cooling system by a heat-absorption machine: "power-heat-cold".

The system consists of a 250kW fuel cell and a heat-absorber which regulates the entire power and temperature needs for the server suite. The power-heat-cold coupling forms a closed loop of interacting sub-systems resulting in an energy efficiency that is twice that of ordinarily powered cooling systems.

Whereas in large conventional utility power systems, some 60% of the primary energy is lost as heat, in the biogas-powered fuel cell the thermal energy is used for cooling the servers. The MCFC generates hot air, reaching temperatures of up to 400°C, which is transformed into cold air by the absorption chamber. This kind of synergy can not be achieved in classic (turbine) engine driven power systems.

Carbon-negative with biogas
Remarkably, this entire system is powered by biogas from energy crops. As such, the system is already highly energy efficient, but the use of locally produced biogas reduces its total primary energy inputs even further: no need to import fossil fuels. The city of München is investing in biogas production using locally grown biogas crops (in Europe, different high-yield and dedicated biogas energy crops are being developed, such as biogas 'super' maize, sudan grass and sorghum hybrids, or tropical grass species). Use of the biogas results in a carbon-neutral fuel cell system. When municipal waste is used the concept could even become carbon negative:

Power & Air solutions is buying the biomethane from Schmack Biogas AG, world leader in green gas production systems (earlier post). Schmack produces biogas in nearby Pliening, where it is purified (the CO2 removed) to a natural gas grade fuel. In Pliening, Schmack feeds the methane into the natural gas grid which brings it to München and to the server suite's fuel cell.

The fuel cell
The Hot Module is a so-called 'molten carbonate fuel cell' which in essence consists of a cylindrical steel vessel, a catalytic burner and a mixing chamber. As with all fuel cells, the electrochemical process is based on a reaction between hydrogen gas and oxygen, which delivers electricity and heat. In the Hot Module, biomethane and steam are introduced at the anode. A catalytic reaction transforms the mixture into hydrogen. During this process, electrons are released at the anode and flow towards the cathode. The electricity that is generated in the process is captured. At the cathode side, carbon dioxide and ambient oxygen react with the electrons to form carbon-ions. These carbon-ions then flow immediately through the electrolyte to the anode. This closes the electrochemical loop.

After RWE Fuel Cell acquired from MTU CFC Solutions, the company has become a fully owned subsidiary of Tognum GmbH. This firm develops stationary, biofuel capable fuel cells for the production of climate-neutral power and heat. Together with its American partner company Fuel Cell Energy, the firm has installed some 35 Hot Modules. The currently marketed high temperature fuel cells deliver a combined 245kW of electricity and 180kW of heat (in a combined heat-and-power configuration). The electrical efficiency amounts to around 50%, considerably above conventional power systems (the efficiency of which ranges between 25 and 35%). In the CHP configuration, overall systems efficiency increases to around 80%.
