Work done by the Swiss Federal Institute of Technology in Lausanne using short burst of photothermal energy on biomass to produce hydrogen yet keeping the carbon intact, is shown in this Science article in The Hindu. These experiments and others are looking at the use of hydrogen as a form of renewable energy. Hydrogen has an impressive energy storage capacity which makes it an attractive source for renewable energy.

To get a clearer picture of the potential and problems with alternative fuels one has to cut through the political lobbying aspects to get an idea of what is doable without environmental consequences. There are many issues connected to the new mandate Congress is writing up for use of 9 billion gallons of fuel made from biomass in 10 years by 2017 and 21 billion gallons by 2022. Since it takes about 700,000 tons of biomass to produce 50 million gallons according to one energy analyst it would require the movement of 126 million tons of biomass from biomass growing areas to biomass plants that convert it into fuel in 2017. This would mean burning energy for transport and would require development of the logistics. The technology isn't here yet but scientists know that biomass can be converted into fuels resembling gasoline or diesel based on the molecular chemistry. Environmentalists and national security groups have joined together to push for this sweeping mandate that the Energy department estimates can replace a third or more of the country's gasoline needs by 2017 or 2022 as the fuel efficiency fuel savings also kick in by that time. The idea is to growthe types ofplant material and straw, switchgrass, that would require very little water and fertilizer to grow. Its the challenge scientists have to take on. And to use tree trimmings, corn stubble and certain kinds of garbage thats a biomass for conversion into fuel. Today about 7 billion gallons of ethanol are made in the USA after Congress passed a law in 2005. Its used mainly as an additive and replaces about 4% of the gasoline used in the USA. Congress new mandate on ethanol calls for an additional 8 billion gallons of ethanol from corn by 2015, in 8 years. Right now corn prices are soaring and corn used as feed for livestock is becoming costlier for meat producers causing them to complain and because it takes about 20 million acres of corn to produce these are acres that cant produce vegetable or fruit or other grain and food producers and processors are complaining that this raises the prices they pay for the inputs they use. So there is a lot of lobbying going on back and forth and some of the statements reflect this. The petroleum industry also does'nt like the idea of nonpetroleum based products and hasnt been too enthusiastic about this mandate and hasnt really made the conversion to their refining and distribution networks for widespread use of these alternative fuels. But Congress is determined and public opinion polls reflect the concerns of a public that is upset about nothing being done about the nationa's dependency on foreign oil. For this see the recent Business Week link. All this is going on while the price of ethanol has slumped and corn price inpouts for ehtanol production are soaring making ethanol less profitable, and see the recent link to the WSJ for this. Congress is responding to grassroots public opinion that wants something done and just as the auto industry learned by its failed lobbying on fuel efficiency the petroleum and other industries are just going to have to live with it it seems. ...

A Berlin based think tank, German Institute for Economic Research, says Germany could end its dependence on energy imports by winter of 2022. That is much sooner than mid-2024 as Economy Minister Habeck has stated.The issue has serious urgency as the war continues in April in Ukraine entering a new and more dangerous phase in the east. And every day oil and gas imports by European Union gives Russia $16 million for coal, $434 million for natural gas, and $489 million for oil, a total of close to $1 billion every day.  With new missile attacks on civilian buildings this is one way for European Union to shoulder some of the burden that it has not done so far. DIW think tank says this could be done with decreased industry and household consumption that could generate about 18-26% savings of the demand for Russian natural gas, suggesting that households turn down thermostats and use less warm water, and industry turn to alternative fuels such as coal and biomass. Another saving is from increased supplies from Norway and the Netherlands of liquefied natural gas (LNG). Increased supplies from Norway alone says DIW could cover 20% of current annual imports of gas from Russia. Instead of waiting to build new infrastructure, the new LNG terminals on the coast which face long construction times and eventually falling demand for natural gas which make them financially untenable, the best approach is to use existing infrastructure in LNG terminals in the Netherlands, Belgium and France to increase volume in EU pipelines. Such action would cover 25% of demand for Russian natural gas. Other action is get more efficient use of the European pipeline system to increase German gas imports from Algeria, Libya and other North African nations vis southern EU nations. ...

A significant part of the haze and air pollution in New Delhi, India, comes from crop burning in the neighboring Punjab and Haryana region. Here the Hindu newspaper looks at the practice that has not changed even after a 2015 government and NGT order banning the practice. This report cites data from the state of Punjab showing 65% of the 1.85 million farming families in the Punjab are small and marginal farmers. The problem is that the rice paddy harvest leaves 19.7 million tons of paddy straw in the fields and the farmers see burning this as a quick way to avoid incurring the cost of machinery and labor. The Punjab government is required to provide machinery to farmers for preventing the burning. Farmers say it has not provided this. Punjab government seeks funding from the central government in Delhi for meeting the cost. Till then marginal farmers continue their old ways creating a thick haze over New Delhi. Solutions proposed are having more biomass plants to generate energy and use the paddy straw, a Happy Seeder variety that takes works with the straw, and shifting to Basmati rice instead of the common rice crop. The way Indian democracy works political parties have remained wary of collectively working out solutions, letting the problem continue.  ...

VW and Daimler both take equal investment share in biofuel company Chroen in Germany. Chroen is in the field of second generation BTL or biomass to liquid, synthetic biofuel. The convictions in Germany are that corn and other agricultural product based fuels are not going to be environmentally friendly as they the process of making fuel from corn takes as much energy and causes as much pollution as it saves. So no carbon dioxide reduction balance is possible with corn based fuel in the view of researchers at VW. Second generation biofuels use wood, plant stalks, or straw, as the raw materials.
