Biofuel Myths and Realities

Wednesday, February 25th, 2009

Pamela Contag is a microbiologist who’s as comfortable in the lab as she is in the boardroom, dealing with the business of running a company. She has plenty of experience there, having helped found two startups: Cobalt Technologies and Xenogen. She also sits on the Department of Energy’s Biomass Advisory Board.

Contag is an astute observer of the biofuels industry. With much of the discussion today focused on second-generation biofuels, she points out that it’s still critical for people not to mix up biofuel feedstocks with human foodstocks. That sure spelled a lot of trouble during the first-generation corn-ethanol buildout, which alarmed the public and still dampens enthusiasm for the biofuels market.

Contag says there’s a list of myths that need to be addressed in order to keep biofuels on track.

“I think the three biggest myths are, one, technology or feedstock will solve our problem. The second is that climate change, energy security and water security are not somehow related. And the third myth is that solar energy to electricity is going to solve all of our problems.”

As for feedstocks, she says, “I don’t think we have the answer now. But I think we’ll have it in the next five years. What’s needed is for entrepreneurs and investors to look at smaller crops with a unified theme of being able to keep a lot of different seed crops. Think of crops as being renewable but also sustainable in terms of agricultural practices.”

Contag is putting her views to work in her latest startup, Cygnet Biofuels. The company is approaching biofuels with three core fundamentals: low energy, low water and local biomass. It wants to harvest local feedstocks and create fuels like biodiesel for communities, mirroring the early days of electrical utilities in the U.S. “Cygnet believes this isn’t an engineering project but an ecosystem project,” Contag says.

Part of Cygnet’s plan is to integrate a wide-variety of technologies into its power-generation plants, including solar, biodiesel, biobutanol, co-generation and digesters. In the company’s first phase, it plans to produce biodiesel with a business model that calls for extensive partnering to sell the company’s capabilities.

No doubt it will take several years to build out on a local biofuels model. But it sounds like an important step forward. –Lee Bruno

India’s Jatropha Tussle

Monday, December 1st, 2008

The Indian government has welcomed biofuels with open arms. Faced with a rapidly growing economy, the world’s second-largest population and an eye-watering fuel import bill, finding a renewable domestic power source has become a top priority.

The country’s recently-revised national biofuel policy, announced in September 2008, sets out the government’s intentions in black-and-white: to produce 20 per cent of the country’s diesel from crops by 2017, primarily from plantations of jatropha (Jatropha curcas). This means that the oilseed-bearing shrub, already introduced in some states, needs to be planted on an additional 14 million hectares of the country’s so-called ‘wasteland’. This has ignited fierce debate: supporters see the move as the solution to the fuel-versus-food conundrum, while critics are fearful that millions of peasants, who rely on these lands, will lose out.

Wasteland - a misnomer

A far cry from the post-industrial ‘brown field’ sites familiar to planners in the developed world, India’s wastelands have historical resonance. Classified in colonial times as areas that could not be cultivated and which were, therefore, unable to produce revenue, everything from forests to semi-jungle to wetlands fell into the category of ‘wasteland’. But, quite unlike the idea of a barren wilderness, these vast areas - comprising about 25 percent of India’s landmass - are more appropriately described as marginal lands, and have supported millions of the country’s poorest people for centuries.

Traditionally, local communities have looked after these lands as common resources, coming to depend on them for food, fodder, fuel wood and medicine. In terms of their day-to-day importance, the figures speak for themselves: around 20 percent of poor households’ income and over 60 percent of their fuel wood come from common property resources. In the mixed farming systems of the country’s semi-arid regions, some three-quarters of people depend on the commons for grazing. Nationwide, the India-based NGO Foundation for Ecological Security (FES) estimates that the commons contribute up to US$5 billion to poor rural households. And, with investment and proper management, the organisation believes the commons could supply a quarter of the country’s fodder needs. These commons also perform important ecological functions, providing habitats for wildlife, harbouring rainwater and absorbing greenhouse gases.

For whose benefit?

India’s common lands have been under threat for at least the past half-century, with between 25-50 per cent already lost due to population pressure and increasing degradation. Little wonder the proposed jatropha plantations are contentious. “By pursuing the energy security of the few - the middle classes and the rich - we are compromising the livelihood security of the poor,” laments Subrata Singh of FES.

The government has tried to find a win-win solution. In an attempt to help the poor share the rewards of the country’s anticipated biofuel boom, the expansion of jatropha production is taking place through the National Rural Employment Guarantee Scheme (NREGS). Under proposed plans, local communities will be paid to plant, tend and harvest the crop on common land. But critics argue that once jatropha is in the ground, livelihoods will become irrevocably tied to the productivity of the crop and the stability of its market price.

While jatropha supporters point to the crop’s near-magical ability to tolerate harsh, drought-like conditions, others have suggested that official estimates of its productivity on suboptimal land have been exaggerated. If the crop fails to live up to expectations the poor will have traded access to precious land in return for neither food, fodder, fuel, medicine - nor a source of income. “Eventually, planting these areas with biofuels might force people from the land,” continues Singh. “We are concerned they might become ecological refugees and migrate to urban areas for their livelihoods.”

FES has been working with state governments to help communities achieve legal recognition for the wasteland commons. It has already assisted communities in six states to establish long-term leases over the areas they depend on and is promoting investment in land restoration through the NREGS. The organisation is also working with the South Asia Pro-Poor Livestock Programme to document the value of the commons to poor livestock keepers, to protect the land and to help other communities diversify into animal husbandry.

Despite progress in these areas, India is simply too large for FES to protect all the affected communities and jatropha plantations have already swallowed-up pockets of common land. Significantly, in the same month that the government unveiled its new biofuels target, state-run refinery Bharat Petroleum announced plans to invest US$480 million in jatropha production. The race for ‘wasteland’ is well underway.
